How to Add VAT to a Price

When you need to calculate the VAT-inclusive price from a net (ex-VAT) price:

Price including VAT = Net Price × 1.20
(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 PriceVAT (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:

Net Price = Gross Price ÷ 1.20
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 RateAdd 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:

  • 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.

Frequently Asked Questions About UK VAT

Do I need to register for VAT if my turnover is below the threshold?
No, VAT registration is only mandatory when your taxable turnover exceeds 90,000 pounds in any rolling 12-month period (as of April 2024). However, you can voluntarily register at any turnover level. Voluntary registration can be beneficial if you sell mainly to VAT-registered businesses, as it allows you to reclaim VAT on your business purchases. The trade-off is the administrative burden of submitting quarterly VAT returns and maintaining compliant digital records under Making Tax Digital rules.
What is the VAT Flat Rate Scheme and who can use it?
The VAT Flat Rate Scheme is a simplified method where you pay a fixed percentage of your gross turnover to HMRC instead of calculating the difference between output and input VAT. The percentage varies by business sector, ranging from 4% for retailing food to 14.5% for computer and IT consultancy. You can join the scheme if your VAT-taxable turnover is 150,000 pounds or less (excluding VAT). New businesses in their first year of VAT registration receive a 1% discount on the flat rate. While simpler, the scheme may not suit businesses with significant VAT-eligible purchases.
Can I claim VAT back on business expenses in the UK?
Yes, if you are VAT-registered and use the standard VAT accounting method, you can reclaim VAT (input tax) on most business-related purchases. This includes office supplies, professional services, equipment, and business travel. However, there are exceptions: you cannot reclaim VAT on business entertainment, company cars (unless used exclusively for business), or goods purchased for personal use. You must hold valid VAT invoices as evidence. For purchases under 250 pounds, a simplified VAT invoice is acceptable; for larger amounts, a full VAT invoice showing the supplier's VAT number is required.
