Partial exemption VAT: what happens if your business has taxable and exempt sales?

If your business makes both taxable and exempt sales, VAT can quickly become more complicated than a standard quarterly return. You may be charging VAT on some income, not charging VAT on other income, and paying VAT on costs that support both sides of the business.

That is where partial exemption VAT comes in.

For many businesses, the issue is not the sales VAT. It is the VAT you reclaim on your costs. If a cost relates to taxable sales, you can usually reclaim the VAT. If it relates to exempt sales, you usually cannot. If it relates to both, you need a fair method to work out how much VAT you can recover.

This is where getting support from a VAT return accountant can help you avoid mistakes, missed claims and unnecessary HMRC problems.

What does partial exemption mean?

You are partly exempt if your VAT-registered business makes both taxable and exempt supplies and has costs that relate to both.

Taxable sales include standard-rated, reduced-rated and zero-rated supplies. Exempt sales are different. You do not charge VAT on them, but they can restrict how much input VAT you can reclaim.

A simple example is a business that provides VATable consultancy services but also receives exempt rental income. Another example could be a company that sells taxable products while also making exempt financial or insurance-related supplies.

The important point is this: zero-rated sales are still taxable sales. Exempt sales are not.

Why partial exemption matters

Partial exemption affects your input VAT, which is the VAT you pay on business purchases and expenses.

You usually need to split your VAT costs into 3 groups:

Costs linked only to taxable sales
You can usually reclaim the VAT in full.

Costs linked only to exempt sales
You usually cannot reclaim the VAT.

Mixed or overhead costs
These support both taxable and exempt activity, so you need to apportion the VAT.

Mixed costs can include rent, utilities, software, phone bills, accountancy fees, marketing, general office costs and other overheads. This is often where businesses get caught out, because they assume all VAT on general expenses is recoverable.

If you use VAT return filing services, your accountant can review these costs before your return is submitted, rather than trying to fix the issue later.

How do you calculate how much VAT you can reclaim?

Most partly exempt businesses use the standard method unless HMRC has approved a special method.

Under the standard method, you usually calculate the percentage of taxable sales compared with total sales, then apply that percentage to your residual input VAT. In plain English, you are working out how much of your shared business costs support taxable activity.

For example, if 75% of your sales are taxable and 25% are exempt, you may be able to reclaim 75% of the VAT on shared overhead costs, depending on your exact position.

This sounds simple, but the detail matters. Some supplies may need to be excluded from the calculation if they distort the result. Some costs may need to be treated directly rather than included in the shared pot. If the standard method does not give a fair outcome, a different approach may be needed.

This is one reason why professional VAT accountants services can be useful for businesses with mixed income.

What is the de minimis rule?

The de minimis rule can help smaller partly exempt businesses recover all their input VAT, including VAT linked to exempt supplies, if the exempt input VAT is below the permitted limits.

In broad terms, your exempt input VAT must be no more than £625 per month on average and no more than half of your total input VAT for the relevant period.

If you pass the test, you may be treated as fully taxable for that period and reclaim all input VAT. If you fail, the VAT linked to exempt supplies is normally restricted.

This is not something to guess. You still need proper records and a clear calculation. If you reclaim too much VAT and HMRC later reviews your return, you may need to repay VAT, with possible interest and penalties depending on the circumstances.

What happens at the year end?

Partial exemption is not only a quarterly issue. Your VAT recovery during the year is usually provisional. At the end of your partial exemption year, you need to complete an annual adjustment.

This adjustment compares what you reclaimed during the year with what you were actually entitled to reclaim based on the full year’s figures. You may end up reclaiming more VAT, or you may need to repay some.

This can be frustrating if you have treated VAT returns as separate one-off tasks. In reality, partial exemption needs a joined-up view across the year. Good bookkeeping makes a big difference, especially if your taxable and exempt income changes from one period to the next.

If you are already using cloud software, a certified QuickBooks accountant can help make sure income and costs are coded properly from the start.

Common partial exemption mistakes

A common mistake is treating exempt sales like zero-rated sales. They are not the same. Zero-rated sales can still allow VAT recovery. Exempt sales can restrict it.

Another mistake is reclaiming all VAT on overheads without checking whether those overheads support exempt activity. This can happen easily when bookkeeping is rushed or when the person preparing the VAT return does not fully understand the business.

Some businesses also forget the annual adjustment. They submit each VAT return, move on, and only realise later that their year-end position should have been reviewed.

You should also be careful if your business changes. Taking on a new exempt income stream, buying property, adding rental income, changing your service mix or restructuring your activities can all affect VAT recovery.

This is where experienced vat accountants can help you look beyond the numbers on one return.

What records should you keep?

You need clear records showing how your VAT has been treated. That includes sales invoices, purchase invoices, VAT receipts, bank records, bookkeeping reports, partial exemption calculations and annual adjustment workings.

You should be able to show which costs relate to taxable sales, which relate to exempt sales and which are shared. If you cannot explain your calculation, it will be much harder to defend your VAT position if HMRC asks questions.

Businesses using VAT returns services often benefit from having the calculation reviewed regularly, especially where income streams change during the year.

When should you get help?

You should get help if you make exempt sales, receive rental income, work in financial services, provide mixed services, deal with property, or are unsure whether your VAT recovery is correct.

You may also need advice if you are growing, opening in a new location, changing software or catching up on old VAT returns. As experienced accountants in Slough, Asmat & Co supports businesses that need practical, clear guidance rather than confusing VAT jargon.

If your business is based nearby, their team also includes accounting firms in Reading support for local businesses that need help with VAT, bookkeeping and tax compliance.

Partial exemption can also affect wider reporting. If your VAT figures are wrong, your year-end accounts and tax position may also need a closer look. That is why it can be useful to combine VAT support with tax return accounting services and regular bookkeeping.

For businesses with employees, payroll and VAT deadlines often fall close together, so joined-up support such as payroll accountant services in Slough can help keep everything organised.
