What is the standard Belgian corporate tax rate?

The standard corporate income tax (CIT) rate in Belgium is 25%. This applies to all taxable profits of companies that do not qualify for the SME reduced rate.

What is the SME reduced rate and who qualifies?

Qualifying SMEs pay 20% on the first €100,000 of taxable profit; any profit above that is taxed at 25%. To qualify, a company must (among other conditions) have at least one manager paid a minimum salary of €45,000, have fewer than 100 FTE employees, not be part of a group with a large consolidated balance sheet, and not be a holding or investment company.

Does this calculator include the crisis surcharge?

No. Belgium abolished the 2% crisis surcharge (crisisbijdrage) as of the 2021 tax year (income year 2020). This tool reflects the current rates without any surcharge.

Is taxable profit the same as accounting profit?

Not necessarily. Taxable profit is your accounting result adjusted for Belgian tax add-backs and deductions (e.g., disallowed expenses, investment deductions, notional interest deduction). Enter the tax-adjusted figure for an accurate result.

Does Belgium have a minimum tax base?

Yes. Since 2023, large companies (taxable base above €1 million) are subject to a minimum tax base rule that limits the use of certain deductions to 70% of the taxable base exceeding €1 million. This tool computes tax on the full profit figure you enter and does not apply that limitation automatically.

Can I use this for a branch or permanent establishment?

Belgian branches of foreign companies pay CIT on Belgian-source profits at the same 25% standard rate. The SME reduced rate generally does not apply to branches. Use the standard company option for branches.
