How to Calculate VAT Manually
Understanding the math behind Value Added Tax is vital for accurate accounting and invoicing. Here are the two core formulas used by our tool:
Adding VAT (Net to Gross)
Multiply your net amount by (1 + VAT rate). For 20% VAT: **Net x 1.20**.
Removing VAT (Gross to Net)
Divide your gross amount by (1 + VAT rate). For 20% VAT: **Gross ÷ 1.20**.
For more complex scenarios involving historical rates or specific exemptions, you can also refer to external resources like Calculate VAT UK for alternative calculation methods.
Current UK VAT Rates
*Different rates apply specifically to items like children's car seats (5%) and most food or publications (0%).
VAT Registration
You must register for VAT if your taxable turnover exceeds **£90,000** over any 12-month period.
Voluntary registration is possible even if your turnover is lower, which can be beneficial if you sell mostly to other VAT-registered businesses.
Flat Rate Scheme
Designed for small businesses with turnover under **£150,000**. You pay a fixed percentage to HMRC based on your industry.
While you can't reclaim input VAT on most purchases, it simplifies bookkeeping significantly.
Payment Deadlines
VAT returns are typically submitted every 3 months. Payment is due **1 month and 7 days** after the end of the VAT period.
Late payments incur significant surcharge penalties ranging from 2% to 15% of the tax due.
