Belgium VAT Calculator (TVA / BTW)

Belgian VAT — known as TVA (taxe sur la valeur ajoutee) in French and BTW (belasting over de toegevoegde waarde) in Dutch — is a consumption tax levied on most goods and services sold in Belgium. Every VAT-registered supplier adds TVA/BTW to their prices; every business buyer can generally reclaim the tax they paid from the Belgian Federal Tax Authority (SPF Finances / FOD Financien). Understanding which rate applies — and how to split a price into net and tax components — is essential for preparing invoices, filing quarterly VAT returns, and planning purchase decisions.

This calculator handles both directions of the computation in one place. In Add VAT mode you supply a net amount and the tool returns the TVA/BTW charge and the gross price a customer will pay. In Remove VAT mode you supply a gross (tax-inclusive) amount — for example a retail sticker price — and the tool works backwards to show the underlying net and the embedded VAT element. All four Belgian VAT rate bands are available as a dropdown.

Belgium’s four VAT rate bands

Belgium operates under the EU VAT Directive and uses four distinct rates:

• 21% — Standard rate. This is the default. If a supply is not explicitly listed under a reduced or zero rate, it is taxed at 21%. Electronics, clothing, household goods, professional services, software licences, and most business-to-business transactions all fall here.

• 12% — First reduced rate. Introduced primarily for restaurant and catering services. When you pay a restaurant bill in Belgium, 12% TVA/BTW is included. This band also covers certain demolition and reconstruction works in designated urban renewal zones, phytopharmaceutical (crop-protection) products, and margarine.

• 6% — Second reduced rate. Covers basic necessities that Belgian law treats as social or essential goods: food and non-alcoholic drinks for home consumption, medicines, printed books, newspapers, public transport (bus/train/tram/metro), water from the mains network, and renovation works on private dwellings that are at least ten years old. Agricultural inputs (seeds, fertilisers) also attract 6%.

• 0% — Zero rate. Applies mainly to cross-border movements of goods within the EU (intra-community supplies) and exports outside the EU. The recipient in another EU country accounts for VAT in their own jurisdiction.

How the calculation works

Adding VAT (net to gross):

Gross = Net multiplied by (1 + rate / 100)

TVA/BTW = Gross minus Net

Removing VAT (gross to net):

Net = Gross divided by (1 + rate / 100)

TVA/BTW = Gross minus Net

Both formulas are exact — there is no rounding until the final display step, which follows standard commercial rounding to two decimal places (half-up).

Worked example

A Brussels-based web agency issues an invoice of 1,000 euros net for a software development project. The service does not qualify for any reduced rate, so the standard 21% applies.

1. Select Add VAT mode.
2. Enter 1000 in the amount field.
3. Choose 21% — Standard rate from the dropdown.

Result:

The client pays 1,210 euros. The agency collects 210 euros on behalf of the Belgian state and declares it in their next VAT return.

Now suppose a sole trader received a catering invoice for 726 euros gross (VAT included). The caterer applies the 12% rate.

1. Select Remove VAT mode.
2. Enter 726 in the amount field.
3. Choose 12% — First reduced rate.

Result:

The net element of 648.21 euros is the deductible business expense; 77.79 euros is the VAT that a VAT-registered sole trader could potentially reclaim.
