## How to calculate VAT

| You know | You want | Formula at 21% |
| --- | --- | --- |
| Amount excluding VAT | The VAT | amount × 0.21 |
| Amount excluding VAT | Amount including VAT | amount × 1.21 |
| Amount including VAT | Amount excluding VAT | amount ÷ 1.21 |
| Amount including VAT | The VAT | amount ÷ 121 × 21 |

A common mistake: taking 21% off an amount that includes VAT. 21% of €121.00 is €25.41, but it holds €21.00 of VAT. So always divide by 1.21.

## Which rate applies?

- **21%** is the standard rate. It applies to most services and products, such as consultancy, design, software and repairs.
- **9%** applies to food, drinks without alcohol, books and some labour-intensive services, such as hairdressers.
- **0%** mainly applies to export outside the EU and to supplies to businesses in other EU countries.

If you are unsure about the rate for a product or service, check the VAT table of the Tax and Customs Administration (Belastingdienst).

## Questions

### How do I get the VAT back out of an amount that includes VAT?

Divide the amount by 1.21 for the amount without VAT. The difference is the VAT. At 9% you divide by 1.09.

### Do I round the VAT per line or per invoice?

Both are allowed, as long as you do it consistently. Round to whole cents.

### Is what I enter stored?

No. The calculation happens when the page loads and nothing is stored.
