VAT return deadlines vary by client depending on their VAT stagger group and VAT scheme. For accountants managing a mixed portfolio, keeping track of which client is due when requires either a well-maintained system or the kind of mistake that generates a late filing surcharge. This article explains exactly how the deadlines work.
VAT stagger groups and what they mean
HMRC divides VAT-registered businesses into three stagger groups (1, 2, and 3), which determines which months their VAT quarters end. The quarter-end months for each group are:
| Stagger group | Quarter-end months | Deadline months |
|---|---|---|
| 1 (March stagger) | March, June, September, December | 7 May, 7 Aug, 7 Nov, 7 Feb |
| 2 (April stagger) | April, July, October, January | 7 June, 7 Sep, 7 Dec, 7 Mar |
| 3 (May stagger) | May, August, November, February | 7 July, 7 Oct, 7 Jan, 7 Apr |
The deadline is one calendar month plus 7 days after the end of the VAT quarter (for online returns and payment). For businesses paying by Direct Debit, HMRC extends the collection date by a further 3 days, but the filing deadline remains the same.
Annual Accounting Scheme
Businesses on the Annual Accounting Scheme file one VAT return per year (not four). The return is due 2 months after the end of their annual accounting year. Interim payments are made on account throughout the year (9 monthly payments of approximately 10% of the prior year's bill, starting in month 4, or 3 quarterly interim payments). The balancing payment is due with the annual return.
The Annual Accounting Scheme is common for smaller businesses with relatively stable VAT liabilities. The reduced filing frequency can be a relief for clients but means a larger single reconciliation at year-end.
Cash Accounting Scheme
The Cash Accounting Scheme allows businesses to account for VAT on the basis of payments received and made, rather than on invoices issued. The quarterly deadlines are the same as standard accounting — the difference is in how the figures are calculated, not when they are due.
The new VAT penalty regime (from 1 January 2023)
HMRC replaced the default surcharge regime with a points-based penalty system from 1 January 2023. The key elements are:
- Late submission penalties: Each late return earns a penalty point. A threshold of points (4 for quarterly filers, 2 for annual filers) triggers a £200 fixed penalty, plus £200 for each subsequent late return.
- Late payment penalties: If the VAT owed is paid 1–14 days late, no penalty applies (but interest accrues). 15–30 days late: 2% of the outstanding amount. After 30 days: a further 2% (totalling 4%). After 31 days: daily rate of 4% annualised.
- Late payment interest: Accrues from the payment due date at the Bank of England base rate plus 2.5%, regardless of when a penalty applies.
The points reset after four consecutive on-time returns (quarterly filers) or two (annual filers). The regime rewards catching up — but the fastest way back to zero is a consistent string of on-time filings.
Tracking VAT deadlines across a client portfolio
For accountants managing clients across all three stagger groups, the practical challenge is that 12 VAT deadlines fall across the year and no two clients necessarily share the same one. A monitoring tool that can track each client's stagger group and flag the approaching deadline is significantly more reliable than a shared calendar or reminder spreadsheet.
