A payment plan (also called an instalment arrangement or a time-to-pay arrangement) is the negotiated agreement by which a tax debtor pays a liability in pieces over time rather than in one lump. In Zimbabwe the legal root of the power is not a special "payment-plan section"; it is the ordinary payment provision itself. Section 71(1) of the Income Tax Act [Chapter 23:06] provides that tax "may be paid in 1 sum or in instalments of equal or varying amounts as may be determined by the Commissioner, having regard to the circumstances of the case". That single clause — the Commissioner's discretion to spread payment — is the statutory foundation of every debt-management instalment plan ZIMRA grants.

It is essential to distinguish two different "instalment" regimes that students constantly confuse. The first is the statutory instalment regime for provisional tax in Section 72: every provisional taxpayer pays current-year income tax in four Quarterly Payment Dates (QPDs) — 10% by 25 March, 25% by 25 June, 30% by 25 September and 35% by 20 December of the relevant year of assessment (Section 72(7)). That is a mandatory, pre-scheduled spreading of the charge before it ever becomes a debt — not a remedy for a debtor in arrears. The second is the discretionary payment plan for an existing debt under Section 71(1): the Commissioner agrees to accept an overdue (or about-to-be-overdue) liability in instalments. This lesson is principally about the second, but it teaches the first because Section 72 is both the model of "tax in instalments" and a frequent source of the very debts that later need a plan. A useful third variant sits between them: under Section 72(14) (inserted by the Finance Act of 2017) a taxpayer who qualifies as a "small or medium enterprise" may, on application, pay provisional tax monthly, one month at a time in advance — a softer instalment cadence for smaller businesses.

The most important — and most misunderstood — feature of any payment plan is what it does not do. A payment plan does not stop interest. Under Section 71(2) interest, at a rate fixed by the Minister by statutory instrument, runs on "so much of the tax … as from time to time remains unpaid" from the due date until the tax is paid in full. An instalment arrangement merely schedules the capital repayments; the unpaid balance keeps accruing interest throughout. The only way interest is switched off is if the Commissioner exercises the special-circumstances proviso to Section 71(2) and "extend[s] the time for payment of the tax without charging interest" — and MR Bank Ltd v ZIMRA 19-HH-779 confirms that a deliberate misapplication of funds is not a "special circumstance" deserving that indulgence. So the default rule is: plan or no plan, interest keeps running.

A payment plan is also the principal vehicle through which the pay-now-argue-later rule is softened. Because Section 69 (income tax) and Section 36 of the VAT Act [Chapter 23:12] provide that the obligation to pay is not suspended by an objection "unless the Commissioner so directs", a debtor disputing an assessment cannot stop collection merely by objecting (Mayor Logistics (Pvt) Ltd v ZIMRA 14-CC-007). In practice the Commissioner's "direction" to suspend is frequently granted on terms — a part-payment plus an instalment plan for the balance. The payment plan is thus not only a debt-management tool but the price of breathing room while a dispute runs.

The conditions of a plan are administrative, not statutory: ZIMRA's Debt Management practice (operated through the TaRMS Self-Service Portal) expects the debtor to apply before the due date (the revenue is far more receptive before arrears harden), to disclose the full liability across all tax heads, to keep current obligations current while paying off the old debt, and to honour every instalment on time. A plan in good standing preserves the taxpayer's tax clearance (ITF 263) — covered in the Tax Clearance Certificates lesson — which is itself often the liquidity lifeline the plan depends on. The default consequences are severe and immediate: a missed instalment causes the arrangement to lapse, the entire remaining balance becomes due at once, the enforcement ladder resumes (demand → garnishee under Section 58 / VAT Section 48 → attachment and sale → civil judgment), the ITF 263 is liable to revocation, and any amnesty (TA01) or voluntary-disclosure (VDA01) relief that was conditioned on the plan is invalidated — because the relief is granted subject to a condition subsequent of full performance. The lesson that follows walks Section 71(1) and Section 72 clause by clause, distinguishes the regimes, shows worked USD instalment schedules (with the running-interest overlay), integrates the case law, and maps the default cascade.

A tax liability does not always arrive at a convenient moment. A business may have a genuinely assessed debt — VAT it charged but could not remit because a customer defaulted, income tax on a profitable year whose cash was reinvested, PAYE caught up in a liquidity squeeze — and yet lack the cash to pay it all at once. The State's interest is in collecting the revenue, ideally in full; a debtor pushed into insolvency by an unaffordable lump-sum demand may pay nothing. The payment plan is the pragmatic bridge: ZIMRA accepts the debt over a schedule the debtor can actually meet, the revenue is collected (with interest), and the business survives to keep generating future tax.

This is why the power lives in the payment provision (Section 71) rather than the enforcement provisions. It is a management-stage tool, sitting in the debt lifecycle established in the Introduction to Tax Debt Management lesson: creation → management/payment → enforcement → extinguishment. The payment plan is the principal instrument of the management stage — the cooperative alternative to the coercive enforcement ladder. A debtor who engages early and secures a plan steps off the enforcement escalator; a debtor who ignores the debt is pushed up it (demand → garnishee → attachment).

Why the topic is examinable and audited

Payment plans test whether a candidate understands three interacting rules at once:

• the discretion to spread payment (Section 71(1));
• the interest that never stops (Section 71(2) and its proviso); and
• the pay-now-argue-later overlay (Section 69 / VAT Section 36), because plans are so often the vehicle for a suspension on a disputed debt.

ZIMRA debt-management interest is high because a well-run plan converts a doubtful debt into a collected one, while a poorly policed plan simply delays enforcement and lets interest balloon. For the practitioner, advising on when to seek a plan, what terms to accept, and how to avoid the catastrophic default cascade is core competence.

Terminology used in this lesson

• Payment plan / instalment arrangement / time-to-pay arrangement — a Commissioner-approved schedule to pay an existing tax debt in instalments under Section 71(1).
• Provisional tax / QPD — the mandatory four-instalment regime for current-year income tax under Section 72 (Quarterly Payment Dates).
• Instalment — one scheduled payment under either regime.
• Default — failure to pay an instalment on time, which causes a discretionary plan to lapse.
• Acceleration — the consequence of default: the whole remaining balance falls due immediately.
• Good standing — a plan being honoured on schedule, which preserves the ITF 263 and any conditional relief.

B.1 Section 71(1) — the discretionary instalment power

Section 71(1) of the Income Tax Act [Chapter 23:06] ("Appointment of day and place for payment of tax") reads:

"Tax shall become due and payable on such date and shall be paid on or before such days and at such places as are fixed or prescribed by or under this Act or, where no such time or place is so fixed or prescribed, as may be notified by the Commissioner, and may be paid in 1 sum or in instalments of equal or varying amounts as may be determined by the Commissioner, having regard to the circumstances of the case: Provided that nothing herein contained shall deprive any taxpayer of the right to pay his tax through the post."

The load-bearing words are "in instalments of equal or varying amounts as may be determined by the Commissioner, having regard to the circumstances of the case". Three points follow:

1. The power is a discretion of the Commissioner — the taxpayer has no right to a plan; he must apply and persuade. The Commissioner weighs "the circumstances of the case" (the debtor's cash-flow, history, the debt's collectability).
2. The instalments may be of "equal or varying amounts" — the plan can be back-loaded, front-loaded, stepped or level. This flexibility lets the schedule track the debtor's expected cash-flow (e.g. smaller instalments now, larger after a seasonal upturn).
3. The provision is annotated in the Act with Mayor Logistics (Pvt) Ltd v ZIMRA 14-CC-007 — the pay-now-argue-later authority — signalling that the instalment discretion and the suspension discretion are administered together.

B.2 Section 71(2) — interest never stops (and the only switch-off)

Section 71(2) provides that where tax is not paid on the due date:

"interest, calculated at a rate to be fixed by the Minister, by statutory instrument, shall be payable on so much of the tax or an instalment of the tax … as from time to time remains unpaid by the taxpayer … beginning on the date specified by the Commissioner … and ending on the date the tax … is paid in full: Provided that in special circumstances the Commissioner may extend the time for payment of the tax without charging interest."

This is decisive for payment plans. The interest clock attaches to whatever "remains unpaid", so a plan that stretches payment over months means interest accrues over those months on the declining balance. The plan reduces capital over time; it does not pause interest. The only relief from interest is the proviso — the Commissioner's discretion to grant an interest-free extension in "special circumstances". The reach of that proviso is narrow: MR Bank Ltd v ZIMRA 19-HH-779 held that a deliberate misapplication of funds is not a special circumstance justifying interest-free time. The rate is fixed by statutory instrument — see SI 212 of 2022 (gazetted 19 December 2022, backdated to 1 December 2022) — the percentage of which is not stated in the Act and must be verified.

B.3 Section 72 — the mandatory provisional-tax instalment regime

Section 72 ("Payment of provisional tax") is the other instalment regime — a statutory, pre-scheduled spreading of current-year income tax. Its mechanics:

• Section 72(2): where a person's taxable income includes an amount on which PAYE is not withheld, that person "shall pay provisional tax on that amount in 4 quarterly instalments". (Annotated Redan Petroleum (Pvt) Ltd v ZIMRA 23-HH-637 — provisional tax is paid through the year, not at year-end.)
• Section 72(3): the provisional taxpayer submits, with a return, an estimate of total taxable income for the year.
• Sections 72(4)–(5): if no estimate is filed, or the Commissioner is dissatisfied with it, he may estimate/increase it, and that estimate is "final and conclusive" — though Section 72(6) makes such a decision subject to objection and appeal.
• Section 72(7) — the QPD schedule:

(A proviso, inserted by the Finance (No. 2) Act 10 of 2022, adjusts these dates where the Commissioner has accepted a non-December year-end under Section 37(13).) - Section 72(8) — set-off allocation: once the year's tax is determined, the Commissioner sets off provisional tax paid against, successively, (i) the tax the person is liable to pay, then (ii) "any other tax or amount due and payable", refunding any balance. This successive set-off is the statutory root of the "oldest-debt-first" allocation discussed in the Payment of Tax Liabilities and Taxpayer Account Management lessons. - Sections 72(9)–(10) — short-payment deemed unpaid: Section 71(2) interest applies to any QPD remaining unpaid after its date; and by Section 72(10) if an instalment paid is less than the prescribed percentage of the tax actually due, the deficit is deemed provisional tax remaining unpaid from that QPD — so under-estimating exposes the taxpayer to interest from the early dates. - Section 72(11) — interest waiver: the Commissioner may waive interest where the taxpayer, "through special circumstances", could not pay, or under-estimated by not more than 10%, or for "any other sufficient cause" (SZ (Pvt) Ltd v ZIMRA 20-HH-142). - Section 72(13)–(14) — de minimis and SME monthly: Section 72(13)(a) exempts taxpayers below a prescribed taxable-income threshold; Section 72(14) (inserted by the Finance Act of 2017, w.e.f. 23 March 2017) lets a qualifying small or medium enterprise pay provisional tax monthly, one month at a time in advance.

B.4 The pay-now-argue-later overlay

Section 69(1) (income tax) and Section 36 (VAT) provide that the obligation to pay is not suspended by an objection or appeal "unless the Commissioner so directs". A payment plan is the usual form such a direction takes: the Commissioner agrees to suspend enforcement of (part of) a disputed debt on condition of an immediate part-payment and an instalment schedule for the rest. The constitutional validity of pay-now-argue-later was upheld in Mayor Logistics (Pvt) Ltd v ZIMRA 14-CC-007.

B.5 The deemed-debt foundation and VAT parallels

Every plan presupposes a debt: by Section 77(1) unpaid tax "shall, when it becomes due or is payable, be deemed to be a debt due to the State". For VAT, the same instalment logic flows from Section 38 (manner of payment) and the Commissioner's general administrative discretion; VAT also offers a deposit/provisional-payment route (Section 38(2)–(3)) by which a registered operator can pay an amount on account to stop or slow the running of the penalty/interest engine while a final figure is settled. VAT interest and the 100% late-payment penalty under Section 39 continue to accrue on the unpaid balance exactly as income-tax interest does under Section 71(2).

C.1 The anatomy of a payment plan

A payment plan under Section 71(1) has the following moving parts:

1. An ascertained debt. There must be a liability that is due and payable (Section 77(1)). If the debt is disputed, the plan typically runs alongside an objection, with the Commissioner directing a suspension under Section 69/VAT Section 36 on the plan's terms.
2. An application. The taxpayer applies — in practice through the TaRMS Debt Management module — disclosing the full liability and proposing a schedule supported by cash-flow evidence. The discretion is the Commissioner's "having regard to the circumstances of the case".
3. A schedule. Instalments of "equal or varying amounts" over an agreed period. A level schedule pays the same each period; a stepped schedule tracks expected cash-flow.
4. The interest overlay. Interest under Section 71(2) (income tax) or the VAT Section 39 / Fifth Schedule engine continues to run on the declining balance throughout, unless the Commissioner grants the special-circumstances interest-free extension (proviso to Section 71(2)). The debtor should therefore prefer the shortest affordable schedule — every extra month is extra interest.
5. Conditions of good standing. Pay each instalment on time; keep current obligations current; do not incur new arrears. A plan in good standing preserves the ITF 263 clearance.
6. The default trigger. Miss an instalment and the plan lapses; the balance accelerates (becomes immediately due); enforcement resumes.

C.2 Why "interest never stops" reshapes the advice

Because interest runs on the unpaid balance, the total cost of a debt rises the longer it is stretched. The practitioner's job is to balance affordability (a schedule the debtor can actually meet, avoiding default) against cost (the shorter the schedule, the less interest). A 24-month plan that the debtor can comfortably service may cost more in interest than a 6-month plan — but a 6-month plan the debtor defaults on is far worse (acceleration + enforcement + clearance loss). The optimum is the shortest schedule the debtor can reliably honour, with a buffer.

The one lever that changes this calculus is the special-circumstances interest-free extension (proviso to Section 71(2); for QPDs, the Section 72(11) waiver). Where the debtor's default arose from genuine special circumstances — not a deliberate choice to use ZIMRA as a cheap lender (MR Bank 19-HH-779) — the Commissioner may extend time without interest. A well-evidenced application for that proviso can be worth more than any rescheduling.

C.3 The provisional-tax regime as both model and debt-source

Section 72 is the State's own instalment plan, imposed on every provisional taxpayer. It illustrates the instalment principle perfectly: spread the year's tax across four dated payments so neither the taxpayer nor the fiscus faces a single year-end shock. But it is also a major source of the debts that later need a Section 71(1) plan: a taxpayer who under-estimates (Section 72(3)) or short-pays a QPD finds the deficit deemed unpaid from the early date (Section 72(10)), accruing interest, and arriving at year-end as an arrears balance. Understanding Section 72 is therefore essential to understanding where payment-plan debts come from and how the Section 72(8) successive set-off allocates payments once the year is determined.

C.4 Default and acceleration — the cascade

A discretionary plan is exactly that — discretionary. It rests on the debtor's performance. On default (a missed or short instalment):

1. The plan lapses. The indulgence is withdrawn.
2. Acceleration. The whole remaining balance is immediately due and payable (it was always a "debt due to the State" under Section 77(1); the plan merely deferred enforcement of parts of it).
3. Enforcement resumes up the ladder: demand → garnishee (Section 58 / VAT Section 48 — appointing the debtor's bank, employer or customers as agents, with no prior notice, CARS 17-HH-110) → attachment and sale → civil judgment (Sections 77–79).
4. ITF 263 revocation. A plan in good standing kept the clearance alive; default exposes it to revocation, which detonates the Section 80 30% withholding-on-contracts and Section 80A/60B gates discussed in the Tax Clearance Certificates lesson — often a larger bleed than the debt itself.
5. Conditional-relief invalidation. Where a VDA01 voluntary-disclosure or TA01 amnesty relief was granted conditioned on paying per a schedule, the relief is subject to a condition subsequent of full performance: missing the schedule invalidates the relief, reviving the penalties and interest it had waived. (Principal is never waived in the first place — see the Write-Offs and Remission and Taxpayer Engagement & Compliance lessons.)

The lesson of the cascade is that a payment plan is a discipline, not a holiday. The debtor must treat each instalment as immovable and renegotiate early if circumstances change, because silence-then-default is far costlier than a proactive variation request.

The figures below are illustrative. The interest figures use an assumed annual rate applied to the declining balance and are flagged accordingly; the actual rate must be taken from the governing statutory instrument (see VERIFY flag).

D.1 Individual / sole trader — a level six-month plan

Facts. Tendai owes assessed income tax of USD 6,000, due since 30 April 2025 and unpaid. He applies under Section 71(1) for a six-month level plan of USD 1,000/month beginning 31 May 2025. The Commissioner agrees but (no special circumstances) interest under Section 71(2) continues to run on the declining balance.

Capital schedule and illustrative interest (assumed nominal annual rate r; monthly interest = balance × r/12):

The capital is cleared in six months. Interest is additional and accrues on each month's balance — so Tendai's total outlay exceeds USD 6,000 by the cumulative interest. Two practical points: (a) a shorter schedule (say four months of USD 1,500) would cost less interest; (b) if Tendai's default arose from genuine special circumstances, he should apply for the interest-free extension under the proviso to Section 71(2) rather than simply accept a rescheduling — that, not the schedule, is where the saving lies.

D.2 SME — VAT debt plan, and the cost of default

Facts. Pamberi Hardware (Pvt) Ltd owes USD 12,000 in VAT (principal plus the Section 39 penalty and interest already accrued). It secures a four-month plan of USD 3,000/month. It pays months 1 and 2 (USD 6,000) but misses month 3.

Consequence of default. The plan lapses. The remaining USD 6,000 accelerates and is immediately due. ZIMRA, without prior notice, serves a Section 48 VAT garnishee on Pamberi's bank (CARS 17-HH-110 applies equally to the VAT twin), sweeping available balances. Pamberi's ITF 263 is revoked, so its customers must now withhold 30% under Section 80 on contract payments — a bleed that can dwarf the USD 6,000. The lesson: the plan was Pamberi's protection; the missed instalment cost it far more than the instalment itself. Had cash-flow tightened, Pamberi should have renegotiated the schedule before month 3 fell due, not defaulted silently.

D.3 SME — monthly provisional tax under Section 72(14)

Facts. Zviko Traders qualifies as a small or medium enterprise (Section 2B of the Charging Act). Rather than face four lumpy QPDs, it applies under Section 72(14) to pay provisional tax monthly, one month at a time in advance. Suppose its estimated annual provisional tax is USD 12,000.

Effect. Instead of 10%/25%/30%/35% on the four QPDs, Zviko pays roughly USD 1,000/month in advance, smoothing the burden across twelve months and reducing the risk of a year-end arrears shock. This is not a debt plan (there is no arrears) but a cash-flow-friendly instalment cadence for the current charge — the gentlest of the three instalment regimes.

D.4 Provisional-tax QPD schedule and the short-payment trap (Section 72(7), (10))

Facts. A company estimates provisional tax of USD 40,000 for the 2025 year of assessment. The statutory QPDs apply:

The trap. Suppose the company pays only USD 2,000 on the 1st QPD (instead of USD 4,000). By Section 72(10) the USD 2,000 deficit is deemed provisional tax remaining unpaid from 25 March, and Section 72(9) applies Section 71(2) interest to it from that date. The shortfall does not wait politely for year-end — it begins accruing interest in March. At year-end, Section 72(8) sets off all provisional tax paid against the final liability, then against "any other tax or amount due and payable", refunding any excess. A taxpayer who under-estimated by no more than 10% may seek an interest waiver under Section 72(11) (SZ (Pvt) Ltd v ZIMRA 20-HH-142).

D.5 Large corporate — a plan as the price of a Section 69 suspension

Facts. A manufacturer disputes a USD 1.2 million assessment and lodges an objection. Because Section 69 means the obligation to pay is not suspended by the objection (Mayor Logistics 14-CC-007), ZIMRA is entitled to enforce now. To stop a garnishee on its operating accounts, the corporate negotiates a suspension on terms: it pays USD 600,000 immediately and agrees an instalment plan for the disputed balance, on condition that ZIMRA directs a suspension under Section 69 pending the objection. If the objection later succeeds, a due adjustment is made under Section 69(2) (refund with interest); if it fails, the plan simply continues. The payment plan here is not a debt-management afterthought — it is the mechanism by which the corporate buys the suspension that an objection alone could never deliver.

• Mayor Logistics (Pvt) Ltd v ZIMRA 14-CC-007 (Constitutional Court) — Upheld pay-now-argue-later. Annotated in the Act under Section 71(1). Establishes that an objection does not suspend the obligation to pay; the Commissioner's discretion to suspend (and the instalment discretion under Section 71(1)) is what creates room for a plan on a disputed debt. The doctrinal anchor for D.5.
• MR Bank Ltd v ZIMRA 19-HH-779 — On the proviso to Section 71(2): the Commissioner may extend time for payment without charging interest only in special circumstances, and a deliberate misapplication of funds is not such a circumstance. Defines the narrow gateway to interest relief — the single most valuable thing a payment-plan applicant can sometimes obtain.
• SZ (Pvt) Ltd v ZIMRA 20-HH-142 — On the Section 72(11) interest waiver for provisional tax: confirms the Commissioner's discretion to waive interest where the taxpayer was, through special circumstances, unable to pay, under-estimated by not more than 10%, or had other sufficient cause. The provisional-tax twin of the Section 71(2) proviso.
• Redan Petroleum (Pvt) Ltd v ZIMRA 23-HH-637 — Annotated under Section 72(2): provisional tax is paid in quarterly instalments through the year, not at the end of the year. Confirms the mandatory, pre-scheduled character of the QPD regime and distinguishes it from a year-end settlement.
• Central African Road Services (Pvt) Ltd v ZIMRA 17-HH-110 — The garnishee authority: no prior notice to the debtor before appointing an agent. Relevant because default on a plan revives enforcement, and the first enforcement step is frequently a no-notice garnishee. (See the Garnishee Orders lesson.)
• Afritrade International Limited v ZIMRA 21-SC-003 — Representative-taxpayer authority; relevant where a plan is negotiated by a public officer/representative on behalf of a company (Sections 53–56), and where personal liability (Section 56) can arise if funds earmarked for tax are diverted instead of paid under the plan.

(Zimbabwe's payment-plan rules are predominantly statutory and administrative; where no on-point case exists, the position rests on Section 71, Section 72 and ZIMRA's Debt Management practice rather than on invented authority.)

1. Believing a plan stops interest. It does not. Section 71(2) interest runs on whatever "remains unpaid" until paid in full. Only the special-circumstances proviso switches it off (MR Bank 19-HH-779). Quote a client a plan's cost including the running interest, and apply for the interest-free extension where the facts support it.
2. Confusing provisional-tax QPDs with a debt plan. Section 72 QPDs are a mandatory spreading of the current charge (10%/25%/30%/35% on 25 Mar/25 Jun/25 Sep/20 Dec); a Section 71(1) plan is a discretionary arrangement for an existing debt. They are different instruments with different consequences.
3. Under-estimating provisional tax. A short QPD is deemed unpaid from its date (Section 72(10)) and accrues interest from then — it does not wait for year-end. Estimate realistically; if you under-estimate by no more than 10%, seek the Section 72(11) waiver.
4. Defaulting silently. A missed instalment lapses the plan and accelerates the whole balance, reviving enforcement (garnishee, attachment) and exposing the ITF 263 to revocation. If cash-flow tightens, renegotiate before the instalment falls due — never just miss it.
5. Letting current obligations slip while paying off old debt. A plan covers a specific debt; incurring new arrears (a missed current VAT or PAYE) breaches good standing and can collapse the arrangement. Keep current obligations current.
6. Treating the plan as suspending a dispute. A plan does not decide the objection. If the assessment is disputed, the plan runs alongside the objection, and the suspension of enforcement exists only because the Commissioner directed it under Section 69/VAT Section 36 — withdraw the plan's performance and the suspension falls away.
7. Forgetting the conditional-relief link. Where VDA01 or TA01 relief was granted on a payment schedule, the relief is subject to a condition subsequent: default invalidates the penalty/interest relief. The plan is load-bearing for the relief, not incidental to it.
8. Applying too late. ZIMRA's Debt Management practice is far more receptive before the due date and before arrears harden. Lodging the application early (ideally before default) both improves the terms and preserves the ITF 263.

Work through the questions one at a time. Choose an answer and it is graded immediately, with an explanation and the provision it comes from. Your progress is saved, so you can stop and resume.

• The power to grant a payment plan for a debt is Section 71(1) of the Income Tax Act [Chapter 23:06] — tax "may be paid in 1 sum or in instalments of equal or varying amounts as may be determined by the Commissioner". It is a discretion, not a right; the taxpayer must apply.
• A plan does not stop interest. Section 71(2) runs interest on the unpaid balance until paid in full; the only switch-off is the special-circumstances interest-free extension (proviso to Section 71(2)), narrowly construed (MR Bank 19-HH-779). Prefer the shortest affordable schedule, and pursue the proviso where the facts support it.
• Distinguish the mandatory provisional-tax QPD regime (Section 72: 10%/25%/30%/35% on 25 Mar/25 Jun/25 Sep/20 Dec) from a discretionary debt plan (Section 71(1)). QPDs spread the current charge; a plan reschedules an existing debt. Under-estimated or short-paid QPDs are deemed unpaid from their date (Section 72(10)) and accrue interest then.
• Section 72(14) lets a qualifying SME pay provisional tax monthly in advance — the gentlest instalment cadence. Section 72(8) sets off provisional tax successively against the year's tax then "any other tax or amount due", the root of oldest-debt-first allocation.
• A plan is the principal vehicle for a Section 69 / VAT Section 36 suspension on a disputed debt — an objection alone never suspends collection (Mayor Logistics 14-CC-007). The plan is often the price of breathing room.
• Default is catastrophic: the plan lapses, the balance accelerates, enforcement resumes (garnishee → attachment), the ITF 263 is revoked, and any VDA01/TA01 relief invalidated as a failed condition subsequent. Apply early, keep current obligations current, and renegotiate before missing an instalment — never default silently.

ZIMRA guidance

• Comprehensive Guide to the ZIMRA Self-Service Portal (TaRMS) — Debt Management module: lodging instalment arrangements (ideally before the due date) and monitoring the taxpayer ledger.
• Comprehensive Guide to the ITF 263 — ZIMRA External Guide — a plan in good standing preserves tax clearance; default exposes it to revocation.
• Comprehensive Guide to the VDA01 Voluntary Disclosure Application and Comprehensive Guide to the TA01 Tax Amnesty Application — relief conditioned on a payment schedule (condition subsequent; default invalidates relief; principal never waived).
• Zimbabwe Tax Compliance Calendar — QPD and remittance due dates (note the QPD presentation conflict flagged above; the Act governs).
