What is the standard rate of UK VAT?

The UK standard rate is 20% as of 2026. Most goods and services are charged at 20%. A 5% reduced rate applies to some items (energy, child car seats), and zero rates apply to most food, books and children's clothing.

What is the flat rate scheme?

The Flat Rate Scheme lets eligible small businesses (turnover under £150,000 ex VAT) pay HMRC a fixed percentage of their gross turnover instead of the usual input/output VAT calculation. The percentage depends on industry.

What is reverse charge VAT?

Reverse charge shifts the VAT accounting from the supplier to the customer. It's used for some construction services and most B2B services bought from outside the UK. The customer accounts for both input and output VAT on their return.

Most UK businesses file quarterly. Your filing dates depend on which VAT quarter group you are in. The deadline is one calendar month and seven days after the quarter-end.

UK VAT Returns: A Practical Guide

The five UK VAT rates

20% standard rate — most goods and services.
5% reduced rate — domestic energy, mobility aids for the elderly, child car seats, some renovations.
0% zero-rated — most food (not catering), books, newspapers, children's clothing, public transport. Still appears on the return; just charged at 0%.
Exempt — finance, insurance, education, health, postage. Not on the return at all.
Outside the scope — wages, transactions with non-VAT-registered overseas customers (sometimes), MOT tests.

Schemes you might use

Standard accounting

Charge VAT to customers (output VAT). Reclaim VAT on purchases (input VAT). Pay HMRC the difference quarterly. The default scheme.

Flat Rate Scheme

Pay HMRC a fixed percentage of your gross turnover (turnover including VAT) instead of tracking input/output. Simpler admin. Good for service businesses with low VAT-able expenses.

Cash accounting

Pay output VAT only when customers pay you (not when invoiced). Reclaim input VAT only when you pay suppliers. Helps with cash flow.

Annual accounting

File one return a year, paying installments throughout. Less paperwork — but you don't get money back until year-end if you've overpaid.

Reverse charge: when you account for VAT on someone else's behalf

Reverse charge applies in two main scenarios for UK businesses:

CIS construction services — between VAT-registered subcontractors and contractors. Subcontractor doesn't charge VAT; contractor accounts for it.
Imported services from overseas — if you buy SaaS, advertising or consulting from a non-UK provider, you typically self-account for the VAT.

On the return, reverse-charge transactions appear in both output and input VAT, netting to zero — but they affect Box 6 (sales) and Box 7 (purchases). Get this wrong and your return looks suspiciously off-balance.

The 9 boxes on a VAT return

VAT due on sales and other outputs
VAT due on EU acquisitions (Northern Ireland only)
Total output VAT (Box 1 + Box 2)
VAT reclaimed on purchases and other inputs
Net VAT to pay or reclaim (Box 3 minus Box 4)
Total value of sales excluding VAT
Total value of purchases excluding VAT
EU goods sales (Northern Ireland only)
EU goods acquisitions (Northern Ireland only)

Common mistakes

Reclaiming VAT on entertainment — generally not allowed except for staff entertainment.
Wrong tax point — VAT date is normally the invoice date, not the payment date (unless on cash accounting).
Mixing rates on a single line — split each line by its actual VAT rate, don't blend.
Missing reverse-charge entries in Box 1 and Box 4 — even though they net out, both must be reported.
Pre-registration VAT — you can reclaim VAT on goods purchased up to 4 years before registration (and services up to 6 months) but it's often missed.
