VAT (Value Added Tax) is one of the most significant taxes UK businesses deal with. Whether you're approaching the registration threshold or considering voluntary registration, understanding the rules, deadlines, and penalties is essential for staying compliant with HMRC.
This comprehensive guide covers everything you need to know about VAT registration and returns for the 2025/26 tax year, including the current thresholds, how Making Tax Digital affects your filing, and the new points-based penalty system.
Who Needs to Register for VAT?
You must register for VAT if:
- Your taxable turnover exceeds £90,000 in any rolling 12-month period (compulsory registration)
- You expect your turnover to exceed £90,000 in the next 30 days alone
- You receive goods from the EU worth more than £90,000
- Your business is based outside the UK but you supply goods or services to the UK
You may choose to register voluntarily if your turnover is below the threshold. This is often worthwhile if:
- Your customers are mainly VAT-registered businesses (B2B)
- You want to reclaim VAT on significant business purchases or start-up costs
- It adds credibility and professionalism to your business
⚠️ Important
You must register within 30 days of the end of the month in which you exceeded the threshold. Late registration can result in penalties and backdated VAT liabilities.
VAT Thresholds & Rates for 2025/26
| Threshold / Rate | Amount |
|---|---|
| Compulsory registration threshold | £90,000 |
| Deregistration threshold | £88,000 |
| Standard rate | 20% |
| Reduced rate | 5% |
| Zero rate | 0% |
Most goods and services are charged at the standard rate of 20%. Some items qualify for the reduced 5% rate (e.g., domestic fuel, children's car seats) or zero rate (e.g., most food, children's clothing, books).
Certain supplies are exempt from VAT entirely, including insurance, education, and health services provided by registered practitioners.
How to Register for VAT
You can register for VAT online through HMRC's Government Gateway. Here's the step-by-step process:
- Create a Government Gateway account if you don't already have one
- Gather your information: business details, bank account, estimated turnover, and date you exceeded (or expect to exceed) the threshold
- Complete the online registration at gov.uk — this typically takes around 15-20 minutes
- Receive your VAT registration certificate — usually within 30 working days, containing your VAT number and effective date
- Start charging VAT from your effective date of registration
💡 Tip
You can backdate your registration by up to 4 years. This means you can reclaim VAT on eligible purchases made before you registered — useful for businesses with significant start-up costs.
Making Tax Digital (MTD) for VAT
Since April 2022, all VAT-registered businesses must comply with Making Tax Digital, regardless of turnover. This means:
- Digital record-keeping — you must keep your VAT records digitally using MTD-compatible software
- Digital submissions — VAT returns must be filed through MTD-compatible software, not manually via the HMRC website
- Digital links — data must flow digitally between software programs (no manual copying between spreadsheets)
Popular MTD-compatible software includes Xero, QuickBooks, FreeAgent, and Sage. Most offer affordable plans for small businesses and integrate directly with HMRC.
📋 MTD Compliance Checklist
- Sign up for MTD through your HMRC business tax account
- Choose and set up MTD-compatible software
- Ensure digital links between all record-keeping tools
- Submit your first return through the software (not HMRC portal)
VAT Return Deadlines & Payment Dates
Most VAT-registered businesses file quarterly returns. Your return and payment are due 1 calendar month and 7 days after the end of your VAT quarter.
| VAT Quarter Ending | Return & Payment Deadline |
|---|---|
| 31 March 2026 | 7 May 2026 |
| 30 June 2026 | 7 August 2026 |
| 30 September 2026 | 7 November 2026 |
| 31 December 2026 | 7 February 2027 |
If you pay by Direct Debit, HMRC will collect payment approximately 3 working days after the deadline — but you must still submit your return on time.
Businesses with annual VAT liabilities over £2.3 million must make payments on account (monthly instalments).

Since January 2023, HMRC uses a points-based penalty system for late VAT submissions, replacing the old default surcharge. Here's how it works:
Late Submission Penalties
- You receive 1 penalty point for each late return
- Once you hit the points threshold, you get a £200 penalty for that and every subsequent late return
- The threshold varies by filing frequency: 2 points (annual), 4 points (quarterly), 5 points (monthly)
Late Payment Penalties
| Days Late | Penalty |
|---|---|
| 1–15 days | No penalty (but interest accrues from day 1) |
| 16–30 days | 2% of outstanding VAT at day 15 |
| 31+ days | 2% of VAT at day 15 + 2% of VAT at day 30, plus daily rate of 4% per year |
🚨 Key Change
Unlike the old surcharge system, late payment interest now accrues from day 1 at the Bank of England base rate plus 2.5%. Even a payment one day late will incur interest charges.
Common VAT Mistakes to Avoid
- Late registration — Monitor your rolling 12-month turnover regularly. Exceeding the threshold without noticing can lead to backdated VAT bills and penalties.
- Claiming VAT on non-business expenses — Only reclaim VAT on purchases used wholly for business purposes. Mixed-use items require apportionment.
- Incorrect VAT rates — Applying the wrong rate (e.g., standard instead of zero-rate on children's clothing) can lead to over or under-charging.
- Missing the Flat Rate Scheme savings — If your turnover is under £150,000, the Flat Rate Scheme can simplify your VAT accounting significantly.
- Poor record-keeping — Under MTD, you must keep digital records for at least 6 years. Missing invoices mean you can't reclaim the VAT.
- Forgetting to deregister — If your turnover drops below £88,000, consider deregistering to avoid the administrative burden.
- Not using the annual accounting scheme — Eligible businesses can make interim payments and file just one return per year instead of four.
Popular VAT Schemes
HMRC offers several special schemes that can simplify VAT accounting or improve cash flow for eligible businesses:
| Scheme | Eligibility | Benefit |
|---|---|---|
| Flat Rate Scheme | Turnover under £150,000 | Pay a fixed % of turnover — simpler calculations |
| Cash Accounting | Turnover under £1.35m | Pay VAT only when you receive payment from customers |
| Annual Accounting | Turnover under £1.35m | File one return per year with interim payments |
| Margin Scheme | Second-hand goods dealers | Pay VAT only on the profit margin, not full sale price |
