This lesson assembles everything the TaRMS Essentials course has taught into a single repeating rhythm: what a Zimbabwean taxpayer actually does, in order, every month, on the Tax and Revenue Management System (TaRMS) and its Self-Service Portal (SSP). The earlier lessons taught each return and each payment as a separate skill. A real finance function does not experience them separately — it experiences a cycle that comes around every thirty days, with quarterly and annual obligations layered on top. Mastering the cycle, not just the individual forms, is what produces a permanently clean compliance record and an always-valid tax clearance.

The backbone of the month is two dates. By the 10th of each month, the prior month's PAYE (Form P2) and the whole REV 5 family of withholding-type remittances fall due — REV 5 (withholding taxes), REV 5A (presumptive tax), REV 5B (IMTT), REV 5C (mining royalties), plus Digital Services Withholding Tax (DSWT), presumptive rental income tax, and the minerals levy. The PAYE 10th deadline is fixed by the Thirteenth Schedule, paragraph 3 of the Income Tax Act [Chapter 23:06]. Then the VAT 7 and its payment fall due on the 15th under Section 28(1) of the VAT Act [Chapter 23:12] — a date shortened from the 25th by the Finance (No. 2) Act 7 of 2024, Section 33, with effect from 1 January 2025. This is the lesson's most important warning: ZIMRA's own Zimbabwe Tax Compliance Calendar and the VAT 7 guide still print the 25th, and they are outdated. The Calendar itself states the saving rule — "where this calendar and the legislation appear to conflict, the legislation prevails" — so the correct VAT date is the 15th.

On top of the monthly drumbeat sit the quarterly Provisional Tax (QPD) instalments on the ITF 12B, paid on the 10/25/30/35 split at 25 March, 25 June, 25 September and 20 December (Income Tax Act Section 72(7)), and the annual obligations — the ITF 12C self-assessment return and final income-tax balance, due 30 April for a 31 December year-end (four months after year-end), and the year-end PAYE reconciliation on the ITF 16. Event-driven items — objections (30 days from an assessment), Special CGT (within 30 days of transfer), refund withdrawals and voluntary disclosures — sit outside the recurring cycle and are handled as they arise.

Two rules cut across the entire routine. Currency: where a taxpayer earns in both USD and ZiG, every monthly remittance splits into a USD stream and a ZiG stream that must be filed and paid separately — Section 37AA of the Income Tax Act (and Section 38 for VAT) prevents netting across currencies, and Section 38A penalises paying VAT in the wrong currency. Working-day adjustment: deadlines on the 10th, 15th/25th and 20th include the same day, and where a deadline lands on a weekend or public holiday the next working day is the effective deadline (ZIMRA practice — verify against the current Public Notice).

The SSP turns this calendar into a workflow. Each month the routine is: open Tax Return Management → Pending, work the obligations the system has raised for the period, complete and Submit each return (not merely Save Draft), then go to Payments and settle each liability per currency using the SSP-generated reference, and finally check Notifications and tax-clearance status before closing the month. Do that, in that order, every month, and the compliance routine becomes a fifteen-minute discipline rather than a recurring emergency.

Because the SSP online help (default.htm) is unreachable (it serves an empty JavaScript shell), the screen-level steps below are grounded in the local ZIMRA External Guides (Self-Service Portal, VAT 7, Form P2, ITF 263) and the prior lessons of this course, with ` flags on live-help-only specifics. The deadlines are grounded in the Compliance Calendar cross-checked against the Acts, and every conflict is surfaced rather than smoothed over.

Most tax teaching is organised by tax head — here is VAT, here is PAYE, here is income tax. That is how the law is written and how you learn it. But it is not how compliance is lived. A working bookkeeper does not "do VAT" and then, separately, "do PAYE". She works a month: payroll closes, supplier invoices are captured, the bank is reconciled, and out of that single body of monthly data flow several different returns and payments, each with its own form, its own deadline, and its own currency split. The month — not the tax head — is the true unit of compliance.

This matters because the failures taught in the previous lesson (Common TaRMS Pitfalls) are almost all rhythm failures: a deadline missed because two taxes had different due dates, a nil return skipped because the month was quiet, a draft left unsubmitted because the routine had no final "check it went through" step. A taxpayer who has internalised the routine — who knows that the 10th is the REV 5 / P2 cluster, the 15th is VAT, the 25th of March/June/September and the 20th of December are QPDs, and the 30th of April is the annual reckoning — simply does not make those mistakes. The routine is the antidote to the pitfalls.

It also matters for tax clearance, the prize that ties the whole course together. As established in Automatic Tax Clearance and reinforced in Common TaRMS Pitfalls, a valid clearance under Section 80A of the Income Tax Act, evidenced by the ITF 263, is a status that is on only while every head is compliant. The monthly routine is precisely the maintenance schedule that keeps that status on. Miss one cluster — one late P2, one unfiled nil VAT 7 — and the status flips off across all heads at once. Run the routine faithfully and the clearance simply stays green, month after month, with no special effort.

This lesson is therefore a scheduling and orchestration lesson, not a new-form lesson. It assumes you already know how to file a VAT 7 (see End-to-End VAT Workflow in TaRMS) and a P2 (End-to-End PAYE Workflow in TaRMS); what it adds is the sequence, the cadence, and the SSP click-path that ties them into one repeatable monthly operation, plus the quarterly and annual overlays and the cross-cutting currency and working-day rules.

The compliance calendar is not arbitrary — every date in it is fixed by a provision. Knowing the provision behind each date is what lets you resolve conflicts (like the VAT 15th-vs-25th) correctly.

The monthly cluster — due the 10th

• PAYE (Form P2) — Thirteenth Schedule, paragraph 3, Income Tax Act [Chapter 23:06]. The employer's remittance of tax withheld from employees is due by the 10th of the month following payment.
• Withholding taxes (REV 5), IMTT (REV 5B), presumptive tax (REV 5A), mining royalties (REV 5C), minerals levy, presumptive rental income tax, and Digital Services Withholding Tax (DSWT) — all remitted by the 10th of the following month per the Compliance Calendar's monthly view. Each rests on its own charging provision (the various withholding-tax sections of the Income Tax Act and the IMTT/presumptive regimes of the Finance Act); the unifying administrative fact is the 10th-of-the-month deadline and, for several, the shared REV 5 series of remittance forms.

VAT — due the 15th (the conflict to get right)

• VAT 7 and payment — Section 28(1), VAT Act [Chapter 23:12]. Due by the 15th day of the month after the end of the tax period. The section's amendment history records the migration 5 → 10 → 15 → 20 → 25 → 15, the final move from the 25th to the 15th made by the Finance (No. 2) Act 7 of 2024, Section 33, w.e.f. 1 January 2025.
• The conflict, resolved. ZIMRA's Compliance Calendar (monthly view) and the VAT 7 guide §2.2 still print the 25th. They are outdated. The Compliance Calendar's own "How to use" section and disclaimer both state: "Where this calendar and the legislation appear to conflict, the legislation prevails." The correct date is therefore the 15th, on the Calendar's own terms.
• VAT categories — Section 27. The tax period depends on the registered category: Category C files monthly; Categories A and B file two-monthly on staggered cycles (Category A on the Jan-Feb / Mar-Apr… pairs; Category B on the Nov-Dec / Feb-Mar… pairs, per the Calendar). The 15th-of-the-following-month rule applies to whichever period closed.
• VAT on imported services — Section 13. Accounted for on the VAT 7 (the "single most-missed line", subject to the Section 13(5)(a) carve-out) on the same cycle.
• Nil returns — Section 28(2). A registered operator files even when no tax is payable (Packers International 16-SC-028).

Quarterly — the QPDs on the ITF 12B

• Provisional tax — Section 72, Income Tax Act. Income tax for the year is paid in advance in four Quarterly Payment Dates (QPDs) on the ITF 12B. The Compliance Calendar states the 10/25/30/35 split with instalments at 25 March, 25 June, 25 September and 20 December (the December QPD on the 20th). Each instalment is a percentage of the estimated annual tax for the current year of assessment. `

Annual — the reckoning

• Self-assessment return and final balance — ITF 12C, Section 37A. For a 31 December year-end, the ITF 12C annual self-assessment return and the final balance of income tax (after the four QPDs) are due 30 April — four months after year-end. For a non-December year-end accepted under Section 37(13), shift the QPD and ITF 12C dates by the same number of months.
• Year-end PAYE reconciliation — ITF 16. The employer reconciles the twelve monthly P2s to the ITF 16 (formerly the P.6) after year-end (see End-to-End PAYE Workflow).

Cross-cutting rules

• Currency — Section 37AA (income tax/PAYE) and Section 38 (VAT). Dual-currency earners run a USD stream and a ZiG stream for every remittance, filed and paid separately; Section 38A penalises wrong-currency VAT payment.
• Working-day adjustment. Deadlines include the same day; weekend/holiday deadlines roll to the next working day (ZIMRA practice — `).
• Event-driven items — objections (30 days from assessment, Section 62 income tax / Section 32 VAT); Special CGT (within 30 days of transfer); refund withdrawals; VDA01 voluntary disclosure (per Public Notice). These are not part of the recurring cycle but interrupt it when triggered.

The routine has a natural shape across the month. Think of it in four phases.

Phase 1 — Early month (days 1–7): close the books and gather the data

Nothing can be filed correctly until the prior month's data is closed. In the first week:

1. Close payroll for the prior month and produce the per-employee PAYE figures per currency (USD table for USD pay, ZiG table for ZiG pay — Section 37AA). Capture taxable benefits in remuneration (omitting them makes the employer personally liable — see Common TaRMS Pitfalls).
2. Capture all supplier invoices and sales for the VAT period, separating standard-rated, zero-rated and exempt supplies, and isolating imported services (Section 13) and input tax that is supported by a valid fiscal tax invoice (Section 16 read with Section 12).
3. Identify the month's withholding events — contractor payments without clearance (30% under Section 80, on REV 5), IMTT on electronic transactions (REV 5B), any presumptive, royalty, rental or DSWT triggers.
4. Reconcile the bank so that the figures you are about to declare match what actually moved, and in which currency.

This phase is off-system bookkeeping; the SSP work in phases 2–3 is only as good as the data prepared here.

Phase 2 — By the 10th: file and pay the monthly cluster

This is the busiest deadline of the month. On the SSP:

1. Log in and open Tax Return Management → Pending. The system raises the obligations due for the period — the P2 and any REV 5 / REV 5A / REV 5B / REV 5C / DSWT / rental returns applicable to you.
2. Open the P2, verify Part A (TIN, period, due date auto-populated as the 10th), complete Part B lines 1–5 — (1) total remuneration including benefits, (2) number of employees excluding Section 80 contractors, (3) gross PAYE from the tables, (4) AIDS Levy at 3% of the tax (line 3), (5) total = 3 + 4 — then Submit. If you pay in both currencies, do this twice: a USD P2 and a ZiG P2.
3. Complete each applicable REV 5-series return for the period and Submit.
4. Go to Payments → New Payment, generate the instruction for each liability, and pay per currency using the SSP-generated reference. Confirm each obligation flips to paid.

Everything in this phase shares the 10th deadline, so it is handled as one sitting. The discipline is to do all of it — not just the P2 — and to Submit and pay, not merely save.

Phase 3 — By the 15th: file and pay VAT

1. Open Tax Return Management → Pending and select the VAT 7 for the closed tax period (check the period header — wrong-period filing is a classic pitfall).
2. Verify Part I particulars (note: TIN is not the VAT number) and tick the correct return type (Local / Imported / Special / Diplomatic).
3. Complete Part II output tax (including the Section 13 imported-services line), Part III input tax (only against valid fiscal invoices; apply Section 16(2) denials and Section 16(3) apportionment), Part IV net (output − input − Section 50A VAT-withheld credit ± Section 44 carry-forward), and Part V the currency split.
4. Save Draft, review, then Submit.
5. Go to Payments → Balance and pay each currency stream separately by the 15th — never net USD against ZiG (Section 38 / 38A).

File the nil VAT 7 here too if the period was empty (Section 28(2)).

Phase 4 — End of month: monitor and reconcile

1. Open Notifications and read every item — assessments, audit correspondence, public notices. An assessment starts a 30-day objection clock (Section 62 / Section 32) whether or not you open it, so this is not optional housekeeping.
2. Check tax-clearance status (ITF 263 / Section 80A). If it is anything other than valid, find and cure the default immediately.
3. Reconcile what you filed and paid against your books, and file the acknowledgements. This closes the loop and is your audit defence.

The quarterly and annual overlays

On top of the monthly cycle, four times a year the QPD (ITF 12B) lands — 25 Mar / 25 Jun / 25 Sep / 20 Dec — requiring an estimate of the year's tax and payment of the relevant instalment (10/25/30/35). Once a year, by 30 April, the ITF 12C annual self-assessment and final balance are due, and the ITF 16 PAYE reconciliation is prepared. These overlays attach to the same SSP modules (Tax Return Management for the return, Payments for the money) and obey the same currency and working-day rules; they simply do not recur monthly.

Why the order matters

The phases run in deadline order — 10th, then 15th, then end-month monitoring — so that the busiest cluster is handled first and nothing is left to the day it is due. Reversing the order (doing VAT first, payroll later) risks the 10th cluster slipping. The routine's power is entirely in its sequence and its completeness: same steps, same order, every month.

Individuals (employees and sole traders)

A pure employee has almost no monthly routine — the employer withholds PAYE and remits the P2. The individual's cycle is annual: confirm the employer's reconciliation, and where there are multiple employers or private deductions, file an ITF 1 to reconcile. A sole trader on self-assessment has a lighter monthly footprint (often no VAT if below the US$25,000 threshold, no employees) but still carries the quarterly QPDs (ITF 12B) and the annual ITF 12C by 30 April. For this taxpayer the "routine" is really four QPD dates plus one annual return — but missing a QPD still breaks clearance, so the cadence discipline matters just as much.

SMEs and partnerships — the full cycle

The Compliance Calendar's own profile of a typical small-to-medium company (VAT-registered, has employees, on self-assessment, no mining or gaming licence) is the canonical case: 28 monthly + 4 quarterly + 4 annual = 36 recurring filings a year. Take Acme Cables (Pvt) Ltd from the workflow lessons, dual-currency. A representative January 2026 for Acme:

• By 10 Feb: USD P2 and ZiG P2 for January payroll, plus REV 5 for any contractor withholding and REV 5B for IMTT — each filed and paid in its currency.
• By 15 Feb: the December VAT 7 (Category C, monthly) — USD stream netting USD 1,200 payable (output 30,000 − input 27,000 − WHT 1,800) and ZiG stream ZiG 252,000 (output 810,000 − input 510,000 − WHT 48,000), paid separately (figures reconciled to the VAT 7 guide in End-to-End VAT Workflow). Note the trap: Acme's bookkeeper, reading ZIMRA's Calendar, would diarise 25 Feb and file ten days late — the routine must use the 15th.
• End Feb: read Notifications, confirm the ITF 263 status is valid, reconcile.
• Overlay: nothing this month, but 25 March brings the 1st QPD (ITF 12B) and 30 April brings the ITF 12C and ITF 16 — Acme's finance team diarises these the moment the year opens.

The partnership variant is the same monthly machinery, with the partnership filing its own returns and the partners carrying the income-tax/QPD layer individually.

Large corporates and multinationals

For a large operator the cadence is identical but the volume and delegation differ. The monthly cluster may include DSWT every month (offshore SaaS — Microsoft 365, AWS, Google, Adobe — triggers Digital Services WHT), substantial IMTT, and multi-entity VAT across categories. The routine is typically run by a shared-service team under delegated SSP credentials — which, as Common TaRMS Pitfalls warned, binds the group under Section 80J, so the end-of-month monitoring phase (clearance status, notifications) becomes a governance control, not a clerical afterthought. Multinationals also feel the currency rule most acutely: every one of the 28 monthly filings potentially doubles into USD and ZiG streams, so the routine is built around per-currency discipline from the start.

A scheduling lesson is, by nature, governed by statute and administrative practice rather than by contested case law — the dates come from the Acts and the Calendar, not from disputed interpretation. Honesty requires saying so. The cases that do bear on the routine are those that price the failure to keep it:

• Packers International (Pvt) Ltd v ZIMRA (16-SC-028). Confirms the duty to render even a nil return (VAT Section 28(2)) — the authority behind the "file every period, even quiet ones" discipline that is central to the routine.
• Trek Petroleum (17-SC-056). On the finality of an assessment once the 30-day objection window closes — the reason the end-of-month monitoring phase is not optional: an unread notice still runs the clock.
• Endeavour Foundation (95-SC-095). On remission of PAYE penalties — relevant when a routine slip causes an under-remittance, showing penalty consequences are not always absolute.
• Delta Beverages (16-HH-378). On mandatory 60-day income-tax refund interest (Section 48), contrasted with the discretionary VAT refund interest (Section 45) — relevant when the routine produces a refund position rather than a payment.

There is no case law on the SSP click-path or the calendar dates themselves; those are administrative facts. This lesson states them from the Acts and the Compliance Calendar, with the VAT-deadline conflict resolved on the Calendar's own "legislation prevails" rule rather than by any judicial pronouncement.

The general pitfalls were catalogued in the previous lesson; here are the ones that arise specifically from the rhythm:

1. Pacing VAT to the 25th. The Calendar and VAT 7 guide say 25th; the law (Section 28(1), as amended) says 15th. Build the routine on the 15th.
2. Treating the 10th as "PAYE day" only. The 10th is the whole REV 5 cluster — P2, REV 5, REV 5A/B/C, DSWT, rental. Filing the P2 and forgetting the IMTT or contractor WHT is a default.
3. Skipping the quiet-month nil returns. A quiet month is still a filing month (Section 28(2); Packers International).
4. Forgetting the overlays. The monthly rhythm is so habitual that the quarterly QPD and annual ITF 12C / ITF 16 get overlooked. Diarise them separately at year-open.
5. Single-currency thinking. Running one blended figure where USD and ZiG should be two streams (Section 37AA / Section 38) — every remittance, not just VAT.
6. No working-day buffer. Filing or paying on the exact deadline when it falls on a weekend/holiday, or relying on a late-night transfer that values the next day (Sections 80I–80L). Build in a day or two.
7. No end-of-month monitoring step. Skipping the Notifications / clearance check means assessments age past the 30-day window and clearance breaks unnoticed.
8. Save Draft as the last step. A routine that ends at Save Draft files nothing — the routine must end at Submit + pay + confirm.

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 month, not the tax head, is the unit of compliance. Run the same four-phase routine — close the books → file/pay the 10th cluster → file/pay VAT by the 15th → monitor Notifications and clearance — every month.
• Two backbone dates. The 10th is the REV 5 / P2 cluster (PAYE, WHT, IMTT, presumptive, royalties, DSWT, rental). VAT is the 15th (Section 28(1), shortened from 25th by FA(No.2)7/2024 Section 33 w.e.f. 1 Jan 2025) — ZIMRA's Calendar and VAT 7 guide still say 25th and are outdated; legislation prevails on the Calendar's own rule.
• Overlays. QPDs (ITF 12B) at 25 Mar / 25 Jun / 25 Sep / 20 Dec (10/25/30/35, Section 72); annual ITF 12C + final balance by 30 April and ITF 16 reconciliation (31 Dec year-end; Section 37(13) shifts non-December year-ends).
• Currency is never netted. Every remittance splits into USD and ZiG streams, filed and paid separately — Section 37AA (income tax/PAYE), Section 38 / 38A (VAT).
• Working-day rule. Deadlines include the same day; weekend/holiday deadlines roll to the next working day (ZIMRA practice — verify against current Public Notice). Build a buffer; don't rely on a deadline-night transfer.
• Finish the routine. End each return at Submit, each payment with the SSP reference per currency, and each month with the Notifications + clearance check — the monitoring phase catches the silent 30-day objection clock (Section 62 / Section 32; Trek) and any broken clearance (Section 80A / ITF 263) before they harden.
• Big picture. A faithfully kept monthly routine is the cheapest tax-risk control a Zimbabwean business has: it pre-empts almost every pitfall, keeps the ITF 263 permanently green, and converts compliance from recurring crisis into quiet habit.
