- VAT return and payment deadline: 1 month and 7 days after period end
- HMRC stagger groups: 1, 2, or 3 — dictates your quarter-end months
- MTD for VAT: mandatory for all VAT-registered businesses since April 2022

VAT return periods and stagger groups
HMRC assigns every VAT-registered business to one of three stagger groups. Your stagger determines which months your VAT quarters end in:
| Stagger | Quarter-end months | Filing deadline example |
|---|---|---|
| Stagger 1 | January, April, July, October | Period to 31 Jan → due 7 March |
| Stagger 2 | February, May, August, November | Period to 28 Feb → due 7 April |
| Stagger 3 | March, June, September, December | Period to 31 Mar → due 7 May |
You can request a specific stagger when registering for VAT. Stagger 3 (March/June/September/December) is popular because it aligns with the standard UK tax calendar and many accountants' workflows.
Filing and payment deadlines
Both the VAT return and the payment are due one calendar month and seven days after the end of your VAT period. The deadlines are identical — there is no grace period for payment after filing.
| Period end | Filing and payment deadline |
|---|---|
| 31 March | 7 May |
| 30 June | 7 August |
| 30 September | 7 November |
| 31 December | 7 February |
Direct Debit: Set up a Direct Debit for VAT in your HMRC business tax account. HMRC collects automatically three days after the standard deadline, removing the risk of missed payments. The Direct Debit must be set up before the current period's deadline — it does not apply retroactively.
The 9 boxes on the VAT return
The standard VAT100 return has 9 boxes. Most sole directors only actively complete four or five — the others are zero or auto-calculated:
| Box | What it contains | Notes |
|---|---|---|
| Box 1 | VAT charged on your sales (output tax) | Your sales invoices total × VAT rate |
| Box 2 | VAT on EU acquisitions (reverse charge) | Zero for most UK-only businesses |
| Box 3 | Total output VAT (Box 1 + Box 2) | Auto-calculated |
| Box 4 | VAT reclaimed on purchases (input tax) | VAT paid on business expenses |
| Box 5 | Net VAT payable or reclaimable (Box 3 − Box 4) | The amount you pay HMRC or receive |
| Box 6 | Net value of all sales (ex-VAT) | Your turnover figure for the period |
| Box 7 | Net value of all purchases (ex-VAT) | Your business expenses and purchases |
| Box 8 | Value of goods supplied to EU customers | Zero for most UK-only businesses |
| Box 9 | Value of goods acquired from EU suppliers | Zero for most UK-only businesses |
Flat Rate Scheme: FRS users calculate Box 1 differently — it is your FRS percentage × VAT-inclusive (gross) turnover, not the standard 20% of net sales. Box 6 still shows your net (ex-VAT) turnover. Input VAT is generally not reclaimable under FRS (except capital goods over £2,000).
Worked example: standard rate quarterly VAT
IT consultant, VAT-registered, standard rated services. April–June quarter.
| Item | Net (ex-VAT) | VAT at 20% |
|---|---|---|
| Sales invoiced to clients (Box 6) | £25,000 | £5,000 → Box 1 |
| Software subscriptions (business) | £800 | £160 |
| Broadband (business portion) | £120 | £24 |
| Professional training course | £500 | £100 |
| Total input VAT (Box 4) | £284 | |
| VAT payable (Box 5) | £4,716 |
This return and payment of £4,716 are both due by 7 August.
Making Tax Digital for VAT
Since April 2022, all VAT-registered businesses must keep digital VAT records and submit returns using MTD-compatible software. You cannot manually type figures into HMRC's online portal. Your accounting software submits directly via HMRC's API.
Compatible software includes FreeAgent, Xero, QuickBooks, Sage, and others. If you prefer spreadsheets, bridging software sits between your spreadsheet and HMRC's API — allowing compliant filing without switching to a full accounting package.
What counts as digital records under MTD?
For each sale and purchase, you must digitally record: the date, supplier or customer name, the net amount, and the VAT amount. You do not need to scan or upload every invoice image — but the key data must be entered into your MTD software at or near the time of the transaction.
Correcting errors on submitted VAT returns
Errors found after submission are dealt with in one of two ways:
- Small errors (net error below £10,000, or below 1% of turnover up to a maximum of £50,000): adjust on your next VAT return by adding or subtracting the correction in Boxes 1 or 4
- Larger errors: complete form VAT652 (voluntary disclosure) and submit to HMRC. Voluntary disclosure before HMRC discovers the error significantly reduces penalties
Alternative VAT schemes: Annual Accounting
The Annual Accounting Scheme reduces your filing obligation to one return per year. You make interim payments (9 monthly or 3 quarterly estimated payments) throughout the year, with a balancing payment or repayment when the annual return is filed. Eligible if taxable turnover is below £1.35 million. Good for directors who want to smooth cash flow and reduce quarterly admin.
Common mistakes
- Filing on time but paying late: both the return and payment share the same deadline — missing either triggers penalties
- Claiming VAT on non-business purchases: HMRC scrutinises input tax claims — only claim VAT on genuinely business-purpose expenditure
- Forgetting the fuel scale charge: if the company pays for any personal fuel in a company car, a fuel scale charge applies and must be added to Box 1
- Submitting via the wrong channel: logging into the VAT portal and manually typing figures is no longer MTD-compliant — the submission must come from your software
