What Is the UK VAT Registration Threshold in 2026?

The UK VAT registration threshold is £90,000 of taxable turnover in any rolling 12-month period, as set by HMRC and frozen at this level through at least April 2026 under the Spring Budget 2023 announcement. This is not a calendar-year limit — it applies to any trailing 12-month window, which catches many growing businesses off guard.

The £90,000 threshold has been in place since April 2024, when it rose from £85,000. HMRC's Spring Budget 2023 confirmed the freeze will hold until at least 2026, meaning fiscal drag is pulling thousands of small businesses into VAT registration each year as revenues rise with inflation.

Key threshold facts:

• Mandatory registration threshold: £90,000 taxable turnover (rolling 12 months)
• Deregistration threshold: £88,000 — you can apply to deregister if turnover falls below this
• Voluntary registration: Available at any turnover level below £90,000
• Time to register: You must notify HMRC within 30 days of the end of the month in which you exceeded the threshold (HMRC VAT Notice 700/1)
• Effective registration date: The first day of the second month after you exceeded the threshold

Threshold comparison table:

| Threshold Type | Amount | Notes | |---|---|---|| | Mandatory VAT registration | £90,000 | Rolling 12-month taxable turnover | | Deregistration threshold | £88,000 | Apply if turnover drops below this | | EU VAT registration (example: Germany) | €22,000 | For comparison — much lower | | Australia GST threshold | AUD $75,000 | £38,000 at mid-2026 rates | | India GST threshold | ₹20 lakh (£18,000) | Varies by state and business type |

According to HMRC's VAT statistics (2023-24), approximately 2.6 million businesses are registered for VAT in the UK. Independent research by the Federation of Small Businesses (FSB) found that around 130,000 businesses are estimated to be trading just below the threshold to avoid VAT obligations — a behaviour economists call "bunching."

When Do You Have to Register for VAT in the UK?

You must register for VAT when your taxable turnover exceeds £90,000 in any rolling 12-month period, not just the financial year. HMRC checks turnover on a month-by-month rolling basis, so a sudden spike in sales — even in a single quarter — can trigger mandatory registration.

The two triggers HMRC uses:

1. Historic test: At the end of any month, if your VAT-taxable turnover for the previous 12 months exceeds £90,000, you must register. Notify HMRC by the 30th day of the following month. Your effective VAT date is the first day of the second month after you exceeded the limit.
2. Future test: If you have reasonable grounds to believe your taxable turnover will exceed £90,000 in the next 30 days alone (e.g., you've just won a large contract), you must register immediately — before the 30-day period begins.

What counts as taxable turnover?

• Standard-rated sales (20%)
• Reduced-rate sales (5%)
• Zero-rated sales (0%) — these still count toward the threshold even though the VAT rate is zero
• Sales of business assets

What does NOT count:

• Exempt supplies (e.g., most financial services, insurance, residential property lettings)
• Outside-scope supplies
• One-off sales of capital assets used within the business

A 2024 HMRC compliance report noted that late VAT registration is one of the top five compliance errors for small businesses, with penalties starting at 5% of the VAT due if you register between 9 and 18 months late, rising to 15% for delays over 18 months.

KARR's turnover tracker monitors your rolling 12-month taxable sales automatically and alerts you when you approach the £90,000 threshold, giving you time to prepare — rather than scrambling after the fact.

How Does Making Tax Digital (MTD) for VAT Work?

Making Tax Digital (MTD) for VAT requires all VAT-registered businesses to keep digital records and submit VAT returns using HMRC-recognised MTD-compatible software. MTD for VAT has applied to all VAT-registered businesses since April 2022, with no remaining exemptions except in very limited cases (e.g., insolvency).

MTD for VAT is not optional — it is a legal requirement under The Value Added Tax (Amendment) Regulations 2018 (SI 2018/261). Filing a paper VAT return when you are MTD-mandated is treated as a failure to submit, which triggers a penalty under HMRC's new penalty points regime (effective January 2023).

What MTD for VAT requires:

Requirement	Detail
Digital record-keeping	All VAT transactions must be recorded digitally — no manual spreadsheets unless bridging software is used
Digital links	Data must flow digitally between records and your VAT return with no manual re-keying
MTD-compatible submission	VAT returns must be submitted via HMRC-approved software or API
Record retention	Digital VAT records must be kept for 6 years
Frequency	Standard: quarterly. Annual Accounting Scheme: annually.

HMRC's penalty points system (post-January 2023):

• 1 point per missed submission
• 4 points triggers a £200 fixed penalty + £200 for each subsequent miss
• Late payment interest: Bank of England base rate + 2.5%
• Late payment penalties: 2% after 15 days, 4% after 30 days, additional 4% annualised after 31 days

As of 2024, HMRC had issued over 800,000 penalty points to VAT-registered businesses under the new regime, according to figures released under Freedom of Information requests by tax software firm Avalara. Compliance rates for MTD VAT returns are above 97% for businesses using dedicated software, versus approximately 88% for those relying on spreadsheet bridging tools.

KARR submits VAT returns directly to HMRC via the MTD API, maintaining a fully digital audit trail from invoice to submission — no bridging software needed.

Which Software Is MTD-Compatible for UK VAT?

MTD-compatible VAT software must connect directly to HMRC's API to pull obligation data and push VAT return submissions. HMRC publishes a list of recognised software on GOV.UK. As of June 2026, there are over 600 products listed, but most small business owners need only a handful of core features.

Key MTD software comparison:

Software	Starting Price	MTD VAT	Offline Mode	Non-Accountant UX	UK Pricing
KARR	Free / £12/mo	✅ Direct API	✅ Offline-first PWA	✅ Guided wizard	Free, Pro, Business
QuickBooks	~£14/mo	✅	❌	✅	£14–£38/mo
Xero	~£15/mo	✅	❌	Moderate	£15–£55/mo
FreeAgent	~£19/mo	✅	❌	✅	£19/mo
Sage 50	~£30/mo	✅	Partial	Moderate	£30+/mo
Excel + Bridging	Variable	✅ (bridging)	✅	❌	£0–£15/mo

What to look for in MTD VAT software:

• Direct HMRC API connection (not just bridging)
• Automatic VAT calculation on invoices and purchases
• Digital record-keeping that satisfies HMRC's "digital links" requirement
• Bank feed integration for transaction categorisation
• VAT return review screen before submission
• Audit trail and submission receipt storage

A 2025 survey by the Institute of Chartered Accountants in England and Wales (ICAEW) found that 61% of small business owners found MTD compliance more time-consuming than expected in the first year, but that this dropped to 23% once they had an integrated software workflow in place.

KARR's "What Happened?" guided wizard lets business owners record sales, purchases, and expenses in plain English — the software handles VAT codes, digital links, and MTD submission automatically. No accounting degree required.

What Are the Benefits and Costs of Voluntary VAT Registration?

Voluntary VAT registration below £90,000 turnover is worth considering if your customers are VAT-registered businesses (who can reclaim the VAT you charge) or if you incur significant VAT on purchases. It is a legitimate strategic choice — not just a compliance obligation.

Benefits of voluntary registration:

• Reclaim input VAT on business purchases, potentially saving 20% on costs
• Appear more established to B2B customers (VAT numbers signal business scale)
• Avoid retrospective registration penalties if you misjudge your turnover
• Access to cash accounting and flat rate VAT schemes from the outset

Costs and obligations:

• You must charge VAT on all taxable supplies (may make you less competitive with non-VAT-registered competitors selling to consumers)
• Quarterly MTD VAT return filing obligation begins immediately
• Digital record-keeping requirement applies from day one
• Deregistering later requires HMRC application and can create complications

VAT Flat Rate Scheme (FRS) — quick reference:

• Available if taxable turnover is under £150,000
• You charge customers 20% VAT but pay HMRC a fixed percentage (varies by sector: e.g., 12.5% for consultants, 9.5% for manufacturers)
• Simpler administration but you cannot reclaim input VAT on purchases (except capital assets over £2,000)
• HMRC's flat rate percentages are published in VAT Notice 733

HMRC data from 2022-23 shows approximately 380,000 UK businesses use the Flat Rate Scheme, making it one of the most widely adopted VAT simplification measures available to small businesses.

FAQ

Q: What is the UK VAT registration threshold in 2026? A: The UK VAT registration threshold in 2026 is £90,000 in taxable turnover over any rolling 12-month period. This has been frozen at £90,000 since April 2024 and is confirmed through at least April 2026 per HMRC's Spring Budget 2023 announcement.

Q: Does zero-rated turnover count toward the £90,000 VAT threshold? A: Yes. Zero-rated sales — such as most food, children's clothing, and books — count as taxable turnover for registration purposes even though no VAT is charged. Only exempt supplies (e.g., residential rent, most financial services) are excluded from the threshold calculation.

Q: What happens if I don't register for VAT on time? A: HMRC will charge a late registration penalty of up to 15% of the VAT due from the date you should have registered. You will also owe all the VAT you should have collected from customers — even if you didn't charge them — plus interest. HMRC can assess up to 20 years of back VAT in cases of deliberate non-registration.

Q: What is Making Tax Digital (MTD) for VAT? A: MTD for VAT is HMRC's mandatory digital record-keeping and filing regime. All VAT-registered businesses must keep digital VAT records and submit returns via HMRC-approved MTD-compatible software. It has applied to all VAT-registered businesses since April 2022 under SI 2018/261.

Q: Can I use a spreadsheet for MTD VAT? A: You can use a spreadsheet combined with HMRC-approved "bridging software" that creates a digital link to HMRC's API. However, manual re-keying between your spreadsheet and the bridging tool is not permitted — HMRC requires digital links throughout. Purpose-built software like KARR is simpler and removes the bridging step entirely.

Q: What is the VAT Flat Rate Scheme and is it worth it? A: The Flat Rate Scheme (FRS) lets you pay HMRC a fixed percentage of your gross turnover instead of calculating VAT on every transaction. It simplifies administration but means you cannot reclaim input VAT on purchases. It suits service businesses with low VAT costs; product businesses usually benefit more from standard VAT accounting.

Q: How often do I need to file a VAT return? A: Most VAT-registered businesses file quarterly VAT returns. If you join the Annual Accounting Scheme (available under £1.35m turnover), you file annually but make interim payments. All filings must be via MTD-compatible software regardless of frequency.

Q: Does KARR support MTD VAT filing for UK businesses? A: Yes. KARR connects directly to HMRC's MTD API to submit VAT returns without bridging software. It tracks rolling 12-month turnover, applies correct UK VAT rates, maintains a digital audit trail, and sends threshold alerts when you approach £90,000 — all within its Free, Pro (£12/mo), and Business (£29/mo) plans.
