The substantive rules of the preceding lessons — the charge, timing, value, documentation — converge on a periodic act of compliance: the return. Part V of the VAT Act [Chapter 23:12] (Sections 27–31) organises it. Section 27 divides registered operators into four tax-period categories: Category A (two-month periods ending January, March, May, July, September, November), Category B (two-month periods ending February, April, June, August, October, December), Category C (monthly — compulsory for large operators whose 12-month taxable supplies exceed the statutory threshold, available on written application, and imposable on repeat defaulters), and Category D (periods approved on application for operators whose trade consists solely of agricultural, pastoral or other farming activities below the farming threshold, and analogous separately registered branches). The Commissioner allocates A/B so the two categories are approximately equal in number (smoothing national filing flows) and may move operators between them; category-change events must be notified under Section 25 (Registration lesson). The thresholds carry a tangled amendment history (Finance Acts 10 of 2020, 7 of 2021 and 8 of 2022; the Fourth Schedule to SI 273 of 2003) — date-stamp any figure before use.
Section 28 is the operative duty: for every tax period the operator must furnish a return in the prescribed form and calculate and pay the tax (or compute the refund). The statutory deadline has been a moving target: successively extended from 5 to 25 days through 2009–2012, then shortened by Section 33 of the Finance (No. 2) Act 7 of 2024, with effect from 1 January 2025, to the period ending on the 15th day of the first month after the tax period. The 2026 administration layers a tighter operational cycle on top: ZIMRA's Public Notice 23 of 2026 (citing SI 81 of 2025 and the Finance Act 7 of 2025) required Category A and C returns for the period ended 31 March 2026 by 10 April 2026, with payment by 15 April 2026 — returns online on the TaRMS Self-Service Portal, input tax claimed only through FDMS-validated fiscal invoices auto-populated into the Invoice Management Module, VAT withholding certificates attached where Section 50A agents withheld, and payment in the currency of trade. A return is due for every period whether or not tax is payable or a refund is due (Section 28(2) — ZIMRA v Packers International (Pvt) Ltd 16-SC-028); the Commissioner may extend time in particular cases (Section 28(3), subject to Section 38).
The supporting cast: Section 29 (special returns — the seller under a power of sale (Section 7(1) — Imposition lesson) files a prescribed return within 30 days of the sale, pays the tax out of the proceeds, copies the owner, and both exclude the transaction from their Section 28 returns); Section 30 (the Commissioner may demand further or other returns from any person; and — inserted by the Finance (No. 2) Act 7 of 2024, w.e.f. 1 January 2025 — procuring entities (PRAZ, ministries, departments and tender-procuring organisations) must file monthly tender-award returns by the 10th detailing tenders awarded and values); and Section 31 (assessments — the Commissioner's power to fix the liability where returns are absent, incomplete or not credible, examined in the VAT Assessments and Audits lessons). Section 38 governs the manner of payment: tax is paid in full within the Section 13/28/29 time; where the amount cannot be accurately calculated for reasons beyond the operator's control, the Commissioner may accept a deposit of the estimated liability as a provisional payment, trued up on final determination; and the currency rule — payment follows the currency of the underlying trade: foreign-currency receipts oblige foreign-currency VAT remittance (subsection (4), with the editor's note on SI 142 of 2019: the ZWL's legal-tender entrenchment neither invalidates forex receipts nor relieves the forex payment obligation).
Default is priced by Section 39: failure to pay by the deadline attracts a civil penalty equal to 100% of the tax plus interest at the prescribed rate (per Schedule 5 to SI 273 of 2003; SI 53 of 2021 prescribing the foreign-currency interest rate from 26 February 2021) for each month or part-month — the regime applied in VSL (Pvt) Ltd & 3 Ors v ZIMRA 19-HH-023, V v ZIMRA 19-HH-643 and E.J (Pvt) Ltd v ZIMRA 19-HH-528 — with improperly obtained refunds clawed back as deemed unpaid tax carrying the same penalty and interest. The ZIMRA Comprehensive Guide to the VAT 7 documents the return's field-level mechanics, and the 2026 public notices (01, 07, 11 and 23 of 2026) fix the operational calendar at the 15.5% rate era. Compliance, in short, is a four-question discipline each period: which category am I, what goes in the return, by when must I file and pay, and in which currency?
