The VAT threshold for UK businesses in 2026/27 is £90,000 in taxable turnover over a rolling 12-month period. Businesses must register with HMRC when their taxable turnover exceeds this amount. Registration is also required when taxable sales are expected to exceed £90,000 within the next 30 days alone.
The current VAT deregistration limit is £88,000. Registered businesses may apply to cancel their registration if they expect taxable turnover below this amount over the following 12 months. These rules affect pricing, cash flow, tax reporting and financial planning. This guide explains the current figures, registration deadlines and practical steps for UK businesses.
The VAT registration limit increased from £85,000 to £90,000 on 1 April 2024. It remains unchanged for the 2026/27 tax year. Businesses must compare their taxable turnover with the current limits rather than their profits or total income. The VAT threshold UK businesses must monitor includes standard-rated, reduced-rated and zero-rated taxable supplies.
The following table summarises the current rules.
A business already registered for VAT cannot automatically deregister when turnover falls below £90,000. HMRC applies a separate deregistration test.
Taxable turnover includes the value of qualifying supplies made by a business, excluding VAT.
These generally include:
VAT-exempt supplies and transactions outside the scope of UK VAT generally do not count towards the registration limit.
For example, qualifying zero-rated food sales count towards taxable turnover. However, most exempt insurance services do not.
Businesses providing different types of goods or services should review their VAT classifications carefully. Incorrect classifications may affect registration decisions and future reporting obligations.
HMRC does not use a fixed calendar year or accounting year to determine compulsory registration. Instead, businesses must review taxable turnover at the end of each month, covering the preceding 12 months. This means a business may exceed the limit at any point during its financial year.
A company approaching the VAT registration threshold should review monthly sales figures and upcoming contracts regularly.
Consider a business with the following taxable turnover figures:
These figures are illustrative.
In this example, the business first exceeds the limit during May 2026. It must normally notify HMRC by 30 June 2026. Its effective registration date will generally be 1 July 2026.
Manual spreadsheets can become difficult to maintain when a business issues numerous invoices each month. Cloud accounting software can support more reliable turnover monitoring.
Platforms such as Xero and QuickBooks allow businesses to record sales, categorise transactions and generate financial reports.
A practical monitoring process should include:
A business should not rely entirely on bank deposits when calculating taxable turnover. Payment dates and taxable supply dates may differ.
At Apex Accountants, our bookkeeping services help businesses maintain accurate transaction records, reconcile accounts and prepare financial reports for VAT monitoring.
Crossing the registration limit during a financial year creates immediate responsibilities. Businesses cannot automatically delay registration until their accounting year ends. Knowing when to register for VAT depends on two separate HMRC tests.
A business is required to notify HMRC within 30 days of the end of the month if its taxable turnover exceeds £90,000 in the previous 12 months.
Registration generally takes effect on the first day of the second month after the threshold was exceeded. For example, a business crossing the limit during September 2026 must normally notify HMRC by 30 October 2026. Its effective registration date will generally be 1 November 2026.
A separate rule applies when a business expects taxable sales to exceed £90,000 within the next 30 days alone. Registration takes effect from the date the business first had reasonable grounds to expect those sales. The business must notify HMRC by the end of that 30-day period. This can affect businesses receiving substantial orders or entering high-value contracts.
Several financial and reporting responsibilities begin once registration becomes effective.
1. VAT must be accounted for on taxable supplies
Businesses must account for VAT at the appropriate rate from their effective registration date.
2. Customer invoices may need updating
Businesses cannot issue VAT invoices until they receive their VAT registration number. Interim invoices may require adjustments once registration is confirmed.
3. Eligible input VAT may be reclaimed
Businesses may reclaim qualifying VAT on purchases, subject to HMRC rules and supporting evidence.
4. Digital records become compulsory
VAT-registered businesses must generally maintain digital records and submit returns using Making Tax Digital-compatible software, unless exempt.
5. VAT returns must be submitted
Most businesses submit quarterly VAT returns. The usual submission and payment deadline is one calendar month and seven days after the reporting period ends.
Late registration can result in unpaid VAT liabilities and potential penalties.

A registered business may apply for voluntary deregistration if it expects taxable turnover £88,000 or less during the following 12 months. HMRC may request evidence supporting the forecast. This could include reduced trading activity, cancelled contracts or changes in business operations.
The VAT threshold UK businesses follow for compulsory registration should not be confused with the lower deregistration limit. Businesses must continue meeting their reporting obligations until HMRC confirms the effective cancellation date. Deregistration may also become compulsory if a business stops making taxable supplies.
A business may exceed £90,000 because of a temporary increase in trading activity. HMRC may grant an exception from registration when the business demonstrates that taxable turnover will not exceed £88,000 during the following 12 months. The business must apply for this exception and provide supporting evidence.
Temporary increases do not automatically remove compulsory registration obligations.
Voluntary registration may benefit businesses with taxable turnover below the compulsory limit. It may be particularly relevant to businesses purchasing substantial amounts of VAT-rated equipment, materials or professional services.
However, registration also introduces administrative responsibilities.
Businesses below the VAT registration threshold should compare potential input VAT recovery with additional costs before registering voluntarily.
A business mainly supplying VAT-registered companies may experience different pricing effects from one selling directly to consumers.
VAT registration can affect selling prices, operating margins and working capital.
The main UK VAT rates for 2026/27 are:
A business provides a standard-rated service priced at £100 before VAT.
After registration, the customer invoice would normally show:
Alternatively, maintaining a VAT-inclusive selling price of £100 leaves approximately £83.33 before VAT.
This difference can affect profitability when prices cannot easily be increased.
Businesses should also account for wider operating expenses when preparing cash flow forecasts.
For example, eligible businesses occupying premises in England may qualify for business rates relief. Employers must also budget for payroll expenses using the applicable National Insurance rates and categories.
These obligations are separate from VAT registration but remain relevant to business cash flow.
Once registered, businesses must maintain reliable accounting records and meet HMRC reporting requirements.
Making Tax Digital for VAT generally requires businesses to keep relevant records digitally and submit returns through compatible software. Records should include sales, purchases, VAT amounts and relevant adjustments.
Most VAT records must be retained for at least six years.
Businesses should reconcile sales, purchases and VAT balances before filing each return. Particular attention should be given to credit notes, zero-rated transactions, exempt supplies and reverse charge arrangements.
Late VAT returns can result in penalty points and financial penalties. Late VAT payments may also attract penalties and interest.
A compliance calendar can help businesses track submission dates and payment obligations.
New premises, changes to trading activities and substantial contracts may affect VAT responsibilities. Businesses should review their position before making significant operational changes.
