Do I Need to Charge VAT as a Sole Trader?

If your VAT-taxable turnover goes over £90,000 in a rolling 12-month period, you usually need to register for VAT and start charging VAT on taxable sales.

The important bit is that VAT registration is based on turnover, not profit. That makes this a threshold you need to watch even if your margins are thin.

The simple rule

If your VAT-taxable turnover goes over £90,000 in a rolling 12-month period, you usually need to register for VAT.

It is based on sales, not profit
The period is rolling, not just your tax year
You normally register after crossing the threshold

Turnover vs profit

This catches a lot of sole traders out. A business with £92,000 of sales and £45,000 of expenses still has £92,000 of turnover.

VAT looks at the taxable sales figure before expenses.

When voluntary registration helps

Voluntary registration can be useful if your customers are mostly VAT-registered businesses and you have VATable expenses to reclaim.

When it may hurt

If your customers are individuals, adding VAT can make your prices feel more expensive unless you absorb some of the cost yourself.

Example sole trader scenarios

£72,000 turnover: usually below compulsory registration.

£91,000 turnover: likely registration needed.

£95,000 turnover with £45,000 profit: still likely registration needed, because VAT uses turnover.

Frequently asked questions

Do sole traders need to charge VAT?

Only if they are VAT-registered. Registration is usually required when VAT-taxable turnover goes over the VAT registration threshold.

Is VAT based on turnover or profit?

VAT registration is based on VAT-taxable turnover, not profit. Your costs do not reduce the turnover figure for threshold purposes.

What is the UK VAT registration threshold?

The UK VAT registration threshold is £90,000 of taxable turnover over a rolling 12-month period.

Can I register for VAT before I have to?

Yes. Voluntary VAT registration can make sense if you want to reclaim VAT on business expenses or mainly sell to VAT-registered customers.

Do I charge VAT on every sale?

Not always. Some sales may be zero-rated, exempt, or outside the scope of VAT.

What happens if I register late?

You may need to pay VAT from the date you should have registered, and penalties can apply.

Can I cancel VAT registration later?

You may be able to deregister if your taxable turnover falls below the deregistration threshold.

How do I calculate VAT backwards?

Use a VAT calculator to remove VAT from a VAT-inclusive price. For standard 20% VAT, divide the gross price by 1.2 to get the net amount.
