UK VAT Rates in 2025
The UK has three VAT rates that apply to different types of goods and services:
| Rate | Percentage | Applies To |

| Zero Rate | 0% | Most food, children's clothing, books, newspapers |
How to Add VAT to a Price
When you need to calculate the VAT-inclusive price from a net (ex-VAT) price:
(for 20% VAT)
Example: Adding 20% VAT
Your product costs £100 before VAT:
- £100 × 1.20 = £120 including VAT
- VAT amount = £100 × 0.20 = £20
Quick VAT Addition Table
| Net Price | VAT (20%) | Gross Price |
|---|---|---|
| £50 | £10 | £60 |
| £100 | £20 | £120 |
| £250 | £50 | £300 |
| £500 | £100 | £600 |
| £1,000 | £200 | £1,200 |
| £5,000 | £1,000 | £6,000 |
How to Remove VAT from a Price
When you have a VAT-inclusive price and need to find the net amount:
VAT Amount = Gross Price - Net Price
(for 20% VAT)
Example: Removing 20% VAT
A product costs £120 including VAT:
- £120 ÷ 1.20 = £100 net price
- VAT amount = £120 - £100 = £20
Common Mistake!
Don't calculate VAT by taking 20% off the gross price! £120 - 20% = £96, which is wrong.
Always divide by 1.20 (or multiply by 100/120) to get the correct net price of £100.
VAT for Different Rates
Here are the formulas for all VAT rates:
| VAT Rate | Add VAT (Multiply by) | Remove VAT (Divide by) |
|---|---|---|
| 20% Standard | × 1.20 | ÷ 1.20 |
| 5% Reduced | × 1.05 | ÷ 1.05 |
| 0% Zero Rate | × 1.00 | ÷ 1.00 |
VAT Registration Threshold 2025
From 1 April 2024, the VAT registration threshold increased:
Current VAT Thresholds (2025/26)
- Registration threshold: £90,000 (taxable turnover in 12 months)
- Deregistration threshold: £88,000
You must register for VAT if:
- Your VAT taxable turnover exceeds £90,000 in any 12-month period
- You expect your turnover to exceed £90,000 in the next 30 days alone
Voluntary VAT Registration
Even below the threshold, you can voluntarily register for VAT. This allows you to reclaim VAT on business purchases and can make your business appear more established. However, you'll need to charge VAT to customers and complete quarterly VAT returns.
What is VAT Exempt vs Zero-Rated?
These terms are often confused but have different implications:
| Type | VAT Charged | Claim Back VAT? | Examples |
|---|---|---|---|
| Zero-Rated | 0% | Yes, on inputs | Most food, children's clothes, books |
| Exempt | None | No | Insurance, education, health services |
| Outside Scope | N/A | No | Wages, dividends, donations |

- Unique invoice number
- Your business name and address
- Customer's name and address
- Description of goods/services
- Net amount (excluding VAT)
- VAT rate(s) applied
- Total VAT amount
- Gross total (including VAT)
VAT Return Deadlines
Most VAT-registered businesses file quarterly returns:
Key Deadlines
- Return filing: Within 1 month and 7 days after the quarter end
- Payment: Same deadline as the return
- Method: Most businesses must use Making Tax Digital (MTD) software
Reclaiming VAT on Business Expenses
VAT-registered businesses can reclaim VAT on:
- Stock and raw materials
- Business equipment (computers, machinery, furniture)
- Office supplies
- Professional services (accountancy, legal fees)
- Business travel expenses
- Business vehicle costs (with restrictions)
You Cannot Reclaim VAT On:
- Business entertainment
- Items for personal use
- Purchases without valid VAT invoices
- Non-business expenditure
VAT Flat Rate Scheme
Small businesses (turnover under £150,000) can use the Flat Rate Scheme, which simplifies VAT by applying a fixed percentage to total turnover:
Instead of calculating exact VAT on each transaction, you pay a set percentage (varies by industry, typically 8-14.5%) of your gross turnover to HMRC.
Benefit: Less paperwork and potentially keeping the difference.
Drawback: Cannot reclaim VAT on most purchases.

UK VAT: Important Facts and Figures
Value Added Tax is one of the UK Government's largest revenue sources, generating approximately 161 billion pounds in the 2023-24 financial year according to HMRC statistics. The standard rate of 20% has remained unchanged since January 2011, when it was raised from 17.5%. There are currently around 2.5 million VAT-registered businesses in the UK, and any business with taxable turnover exceeding the VAT registration threshold of 90,000 pounds (from April 2024) must register for VAT.
The UK operates a destination-based VAT system, meaning exports are zero-rated while imports are subject to VAT. Following Brexit, goods imported from the EU became subject to import VAT for the first time since 1993. For small online retailers selling to UK consumers, the rules changed significantly: overseas sellers must now register for UK VAT if their goods are valued at 135 pounds or less, with online marketplaces responsible for collecting VAT on behalf of sellers in many cases. The Making Tax Digital programme requires all VAT-registered businesses to keep digital records and submit VAT returns using compatible software, a requirement that became mandatory for all VAT-registered businesses from November 2022.
