Corporate income tax in Belgium 2026: 25%, the 20% SME rate, the best structure

Last reviewed: November 2026 · Reviewed by Stéphane Gombauld, tax expert, technologist and digital nomad

You are deciding whether to run your activity through a Belgian company, or you already own one and want to check the 2026 rules. Belgium's headline rate is average for Europe, but the SME rate, the participation exemption and the reduced dividend routes make a company attractive for many freelancers and founders. This guide gives you the rates, the conditions, the dividend maths and the residence trap.

Belgium corporate income tax in 2026: the key figures

Is this guide for you?

Read on if you…

• are a freelancer earning enough that a BV/SRL may beat the 50% personal rate;
• already own a Belgian company and want to pay yourself efficiently in 2026;
• run a foreign company and spend most of your time in Belgium.

Probably not your case if you…

• are a sole trader with profits under about EUR 50,000 (the personal route is usually simpler, see business expenses in Belgium);
• work for a multinational and need the group's Pillar Two position.

How is a Belgian company taxed?

A company is a Belgian tax resident if its registered seat, principal establishment or place of effective management is in Belgium. Resident companies pay corporate income tax on worldwide profit. Non-resident companies pay tax only on profit attributable to a Belgian permanent establishment or Belgian real estate.

Taxable profit starts from the accounting profit under Belgian GAAP, then adds back non-deductible costs (disallowed car costs, 31% of restaurant bills, fines) and removes exempt items (dividends under the participation exemption, innovation income). The rate is a flat 25%. There is no municipal surcharge for companies and no separate trade tax.

The notional interest deduction was abolished for financial years from 2023. The innovation income deduction survives: 85% of net income from patents, copyrighted software and similar IP is exempt, giving an effective rate of 3.75% on qualifying profit.

Do you qualify for the 20% SME rate?

The reduced rate applies to the first EUR 100,000 of taxable profit. To qualify, your company must be a small company under the Code of Companies and Associations and pass four tests:

1. Minimum director salary: the company pays at least one individual director a gross salary of EUR 50,000 in 2026, or a salary at least equal to the company's taxable profit if that is lower. From 2026 the threshold is indexed, and benefits in kind may only make up 20% of it.
2. Ownership: shares are not held 50% or more by other companies.
3. Not a financial company: shareholdings do not exceed 50% of paid-up capital plus taxed reserves (participations of 75% or more are ignored).
4. Dividend limit: dividends paid do not exceed 13% of paid-up capital.

Failing any one test puts all profit at 25%. The salary test is the one that catches owner-managers who prefer dividends. Our legal forms of business in Belgium guide explains how the BV/SRL fits these rules.

Which structure: comparison matrix

How do you get money out of the company?

This is where the real tax rate is decided. Profit taxed at 20% or 25% is then taxed again when it reaches you.

Salary

Deductible for the company, taxed in your hands at 25% to 50% plus municipal tax, plus self-employed social security of 20.5%. Expensive above the EUR 50,000 needed for the SME rate, but it builds pension rights.

Dividends

The standard withholding tax is 30%. Two SME routes cut it:

• VVPRbis: dividends on shares issued in cash from 1 July 2013 by a small company are taxed at 20% for distributions from the second financial year after the contribution and 15% from the third year.
• Liquidation reserve: the company sets aside profit and pays a 10% tax immediately. Distributions after a waiting period carry a further 5% (reserves built up to 2025) or 6.5% (reserves built from 2026), with the waiting period cut from 5 to 3 years. On liquidation, no further tax is due.

Combined with the 20% rate, VVPRbis gives an overall burden of about 32% on EUR 100 of profit: 20 in corporate tax, then 15% of the remaining 80. That compares with over 50% on the same income earned personally.

Benefits in kind and expenses

A company car, phone, laptop or housing provided to you is taxed as a benefit in kind. Costs that serve the business are deductible under the rules in business expenses in Belgium.

When does Belgium treat your foreign company as Belgian?

Here's the trap for digital nomads. If you own a company in Estonia, Dubai or Delaware and take its decisions from your flat in Brussels, Belgium can treat the company as resident because its place of effective management is here. It then owes 25% on worldwide profit, with penalties for the years it did not file. The foreign country may still tax it, and relief depends on the treaty.

Even without full residence, your activity in Belgium can create a permanent establishment of the foreign company, so the profit you generate here is taxed here. The right order is to choose where you will actually live, then the entity. Heavnn's business setup service handles that sequence across countries, and our tax residency in Belgium guide covers the personal side.

Moving a Belgian company's seat abroad triggers an exit tax: the company is treated as liquidated and unrealised gains are taxed at 25%, with instalment payment possible for moves inside the EEA.

When and how do you file and pay?

• Financial year: usually the calendar year, but any 12-month period is allowed.
• Return: filed online via Biztax within 7 months of year-end; for a 31 December year-end that means by the end of September 2027 for 2026 profits.
• Prepayments: due on 10 April, 10 July, 10 October and 20 December. Paying nothing in advance costs a surcharge of 6.75% of the tax; small companies are exempt from the surcharge for their first 3 financial years.
• Withholding tax: declared and paid within 15 days of the dividend date.
• Annual accounts: filed with the National Bank within 7 months of year-end.
• UBO register: beneficial owners registered and confirmed annually.

Common mistakes (and what they cost)

• Paying yourself EUR 45,000 to save social security. The SME rate is lost and the full profit is taxed at 25%: EUR 5,000 extra on EUR 100,000.
• Skipping prepayments in year 4. A 6.75% surcharge on the whole tax bill, for no benefit.
• Taking dividends in year 1 under VVPRbis. The 15% rate needs patience; early distributions pay 30%.
• Running a foreign company from Belgium without declaring it. Belgian residence of the company, 25% tax, 10-year audit period and increases up to 200%, as set out in tax fraud regulations of Belgium.
• Lending company cash to yourself. Interest is imputed at the official rate and taxed as a benefit in kind, and the loan draws audit attention.

Frequently asked questions

What is the corporate tax rate in Belgium in 2026?

The standard rate is 25%. Small companies pay 20% on the first EUR 100,000 of taxable profit and 25% above, if they pay a director at least EUR 50,000 and meet ownership and activity tests. There is no municipal or regional surcharge on company profits, and no separate trade tax.

How are dividends from a Belgian company taxed?

Withholding tax is 30% by default. Small companies can pay dividends at 15% under VVPRbis on shares issued in cash from July 2013, from the third financial year after the contribution. Alternatively, a liquidation reserve costs 10% up front and 6.5% on distribution after 3 years, or nothing on liquidation.

Is a BV/SRL better than being a sole trader in Belgium?

Usually from about EUR 60,000 to 80,000 of annual profit. Below that, accounting costs of EUR 2,000 to 4,000 a year and the mandatory director salary eat the saving. Above it, the 20% rate plus 15% dividends gives a combined burden around 32% to 36%, against 50% plus municipal tax personally.

Does Belgium have a participation exemption?

Yes. Dividends received from a holding of at least 10%, or with an acquisition value of at least EUR 2.5 million, held for 1 year in a normally taxed company, are 100% exempt. Capital gains on the same holdings are exempt from corporate tax. The government announced tighter conditions for large companies from 2026.

When is the Belgian corporate tax return due?

Within 7 months of the end of the financial year, filed online through Biztax. For a company closing on 31 December 2026, that means the end of September 2027, subject to the dates FPS Finance publishes each year. Prepayments fall due on 10 April, 10 July, 10 October and 20 December of the financial year.

Can a non-resident own and run a Belgian company?

Yes. There is no nationality or residence requirement for shareholders or directors of a BV/SRL. The practical issues are a Belgian bank account, a registered office, and tax residence: if the company is managed from abroad, that country may tax it. Belgian tax residence follows the place of effective management, not the registered address.
