Businesses over £90,000 turnover must register for VAT, but HMRC may grant exceptions if the increase is temporary.

A business must register for VAT if either of the following applies:

1. At the end of any month, its taxable turnover in the previous 12 months has exceeded £90,000; or
2. At any point, it is reasonable to expect that taxable turnover in the next 30 days alone will exceed £90,000.

If a business temporarily exceeds the VAT registration threshold, they may be able to apply for an exception from VAT registration with HMRC. This applies if their taxable turnover has gone over the threshold in the last 12 months, but the business can show it will not go over the deregistration threshold (£88,000) in the next 12 months. This exception must be applied for by contacting HMRC to request and complete forms VAT1 and VAT5EXC. It’s important to note that this is different from a full VAT exemption.

Once an application is submitted, HMRC will respond within 40 working days to confirm approval or refusal. If approved, the business will not be registered for VAT at that time but will remain required to monitor their turnover monthly in case their circumstances change, and VAT registration is required. If the exception is denied, HMRC will register a business based on the information provided, and the business will be required to account for VAT from the date their liability began.

When considering VAT on entertainment provided solely to directors or partners of a business it is generally not recoverable as VAT Input Tax.

HMRC considers that directors and partners are not in need of entertainment to motivate themselves, so such costs are not for business purposes. However, exceptions apply for subsistence costs (e.g., meals or accommodation during business travel), and no apportionment is needed when directors or partners attend general staff events.

In contrast, VAT incurred on entertainment for employees, such as staff parties, team-building events, or outings, is usually considered by HMRC as a business expense and can be fully recovered.

In cases of mixed entertainment, where both employees and non-employees (e.g., guests) are present, the VAT must be apportioned. Only the portion relating to employees is recoverable. VAT on entertainment for non-employees is generally blocked, unless the guest is an overseas customer, in which case input tax is not blocked, but output tax may apply.

Issuing a VAT invoice without registration or authorisation can lead to HMRC penalties, even if it is done by mistake.

A penalty may be charged by HMRC when an individual or business issues an unauthorised VAT invoice showing or including VAT without being allowed to do so. The invoice does not need to be a formal VAT invoice; it only needs to show an amount that is shown as VAT or includes an amount attributable to VAT.

An unauthorised person is anyone who is not registered for VAT, not part of a VAT group, or not otherwise authorised to act on behalf of a taxable person, such as an insolvency practitioner or an auctioneer selling goods to recover a debt. Common examples include businesses operating below the VAT registration threshold, individuals who issue VAT invoices after deregistration or businesses who begin charging VAT before being VAT registered. Farmers who are not certified to use the VAT agricultural flat rate scheme, but issue flat rate invoices may also face penalties.

A penalty may be avoided if the person has a reasonable excuse for the error. However, unauthorised issuing of VAT-related invoices is treated seriously and may result in financial penalties.

Not all goods and services carry a 20% VAT, knowing the right rate can save costly mistakes.

When a VAT-registered business issues an invoice to their customer, they must ensure that they charge the correct rate of VAT. Whilst most businesses in the UK charge VAT at the standard rate of 20% there are a number of different VAT rates and exemptions to be aware of. This includes the reduced VAT rate of 5% and the zero rate (0%).

There are two other categories that the supplies of goods and services can fall under:

• Exempt – where no VAT is charged on the supply. Examples of exempt items include the provision of insurance, postage stamps and health services provided by doctors. If a business only sells VAT-exempt goods and services, they cannot register for VAT.
• Supplies that are 'outside the scope' of the UK VAT system altogether. These supplies are beyond the realm of the UK VAT system, and you cannot charge or reclaim VAT on these supplies. Examples include goods or services you buy and use outside of the UK, statutory fees (such as the London Congestion Charge) and goods you sell as part of a hobby.

If a business has made an error in charging VAT, then this needs to be corrected. The timing and amount of an error can impact on how the issue is resolved.

There are also penalties if you charge VAT to your customers before you are officially VAT registered. VAT registration is only required for eligible businesses earning more than £90,000 per year although businesses under the threshold can voluntarily apply for a VAT registration.

New rules mean late VAT filings and payments now trigger points, fines and interest charges.

The VAT late filing penalties regime changed for accounting periods beginning on or after 1 January 2023. Under the new system, there are now distinct and separate penalties for late filing of VAT returns and for the late payment of VAT liabilities.

The revised system operates on a points-based approach. A taxpayer receives one penalty point for each VAT return that is submitted late. Once a specific threshold of points is reached, a financial penalty of £200 is charged and the taxpayer is notified.

The penalty thresholds based on VAT return frequency are as follows:

• For monthly VAT returns, the threshold is five penalty points.
• For quarterly VAT returns, the threshold is four penalty points.
• For annual VAT returns, the threshold is two penalty points.

For example, a business that files VAT returns on a quarterly basis will receive a £200 penalty once it accumulates four late submission points. To remove the penalty points and return to a clean compliance record, the taxpayer must submit all VAT returns on time for a continuous period of twelve months. There are also statutory time limits after which a penalty point cannot be issued for a particular late return.

Late payment penalties are applied separately. If VAT remains unpaid between 16 and 30 days after the due date, a first penalty of 2% of the outstanding tax is charged. If the VAT is still unpaid 31 days or more after the due date, a second penalty of 4% of the outstanding amount applies.

In addition, late payment interest is charged from the day payment becomes overdue until it is paid in full.
