VAT Flat Rate Scheme Calculator

A simplified VAT scheme for businesses under £150,000 turnover. Apply a single flat percentage to gross sales instead of tracking input VAT line by line.

You charge customers at the normal 20% rate. You pay HMRC the flat rate (4%–14.5% by sector) on gross turnover. Most input VAT cannot be reclaimed separately. The aim is to reduce bookkeeping for small businesses. Capital purchases over £2,000 on a single invoice are an exception and can still be reclaimed.

VAT-registered businesses with expected taxable turnover under £150,000 excluding VAT in the next 12 months.

You leave when total turnover including VAT exceeds £230,000 in any 12-month period. Several activities are barred: groups, divisions, anyone who has left the scheme in the last 12 months. Apply by including the scheme choice on the VAT1 registration form or by writing to HMRC if already registered.

16.5% — applied to gross turnover regardless of sector if your spending on relevant goods is below the threshold.

You are a limited cost trader if spending on goods is less than 2% of gross turnover, or less than £1,000 a year. Relevant goods means physical items consumed by the business — not services, vehicles, fuel for own use, capital items, food and drink. The test is applied every VAT period, so you can move in and out of LCT status.

Newly VAT-registered businesses get a 1 percentage point discount on the sector rate for the first 12 months.

A management consultant on 14% pays 13% in year one. The discount applies even if LCT — 16.5% becomes 15.5%. The 12 months count from the date of VAT registration, not the date you joined the Flat Rate Scheme. Apply automatically on quarterly returns; HMRC does not check separately.

Flat rate VAT = gross turnover (including VAT charged) × sector rate.

Example: a graphic designer on 14%, net turnover £40,000, charges 20% VAT giving £8,000. Gross turnover £48,000. Flat rate VAT owed = £48,000 × 14% = £6,720. The £1,280 difference is kept by the business. Apply the rate against gross, not net — this catches many first-time users out.

Often no, especially for limited cost traders. Service businesses with very low purchases and a non-LCT sector rate can save £1,000–£3,000 a year.

The 16.5% LCT rate usually leaves you no better off than standard accounting and can leave you worse off if you have significant input VAT to reclaim. Run the numbers using your prior-year actuals before joining. The calculator above does this automatically against an industry-average input VAT estimate.

Not normally — except capital purchases of £2,000 or more (including VAT) on a single invoice.

The flat rate bakes in an average input VAT recovery. The capital exception covers vehicles bought outright, IT equipment bundles, machinery, office furniture sets. The capital item must be for business use, not for resale. Enter the reclaim in Box 4 of the VAT return as normal.

Pick the sector that best fits your main business activity from the HMRC list of 55 categories.

If nothing fits, use the catch-all "Any other activity not listed elsewhere" at 12%. HMRC expects an honest classification — repeated misclassification can trigger a compliance review. If you change activities significantly, change the sector rate and notify HMRC at the next VAT return.

Mandatory exit when total turnover (including VAT) in a 12-month period exceeds £230,000.

Also if you anticipate exceeding £230,000 in the next 30 days. Voluntary exit allowed at any time by writing to HMRC. Once you leave, you must wait 12 months before rejoining. Plan ahead — switching mid-quarter requires recalculating output and input VAT for the changeover period.

No — but the Flat Rate Scheme has its own cash-basis option built in.

You choose at registration whether to apply the rate to invoiced turnover or to cash received. Most small service businesses pick the cash basis to avoid funding VAT before customers pay. The choice is between flat-rate-invoice-basis and flat-rate-cash-basis. Standard cash accounting (Notice 731) is a separate scheme.

Goods used exclusively for the business — stock for resale, raw materials, parts, consumed office supplies.

Excludes: services of any kind, vehicles and their running costs, fuel for own use, capital expenditure, food and drink (own or staff), goods for resale that are leased or hired, and any goods with mixed business and personal use. The test is per VAT period — you can move in and out of LCT status quarter to quarter.

Yes — charge customers at the normal rate (20% standard, 5% reduced, 0% zero-rated) as usual.

The flat rate only affects what you pay HMRC, not what you charge. Your invoices look identical to standard accounting invoices — VAT number, rate, VAT amount, net and gross totals all shown. Customers reclaim the VAT they paid you in the normal way. The difference between VAT charged and flat rate VAT paid is your retained margin.
