The 7 essential tax topics
For a self-employed person in Belgium, seven areas account for most tax decisions and obligations in 2026. Each has its own page with scales, worked examples and trade-offs.
The table below links to each sub-pillar: you can read this hub as an introduction and dive into the topic that concerns you.
Own name or company: what is the tax impact?
Switching to a company (mainly an SRL/BV since the 2019 Companies and Associations Code) profoundly changes your taxation. The 50% marginal personal income tax rate is replaced by corporate income tax at 20 or 25%, but cash taken out of the company is taxed again on the way out (remuneration via personal income tax, or dividends via withholding tax on movable income).
The trade-off becomes relevant from around €60,000 to €80,000 of net annual income, with an effect that is all the stronger if you can leave part of the profit in the company (investment property, IPC, liquidation reserve).
See the details in SRL, switching to a company and SRL dividends.
The 5 most powerful tax optimisation levers
Taken together, these five levers allow a self-employed person in Belgium with ~€80,000 of net income to reduce their annual tax bill by €8,000 to €18,000 depending on their profile, without any aggressive optimisation or exotic arrangements.
[01] PLCI/VAPZ, free supplementary pension for the self-employed
Premium of up to €4,086.34 (standard) or €4,701.54 (social) in 2026, 100% deductible. Typical saving of 50-70% of the premium paid (personal income tax + social security contributions). See the PLCI guide.
[02] IPC, individual pension commitment (through a company)
Reserved for company directors, capped by the 80% rule. Allows €20-30k/year to be deducted from corporate income tax depending on the director's remuneration. See the IPC guide and the 80% rule.
[03] Actual expenses vs flat-rate business expenses
Above ~€15,000/year of documented actual expenses, switching from the flat rate to actual expenses reduces the taxable base by several thousand euros. See deductible expenses.
[04] Liquidation reserve (SRL)
Profit after corporate income tax transferred to a liquidation reserve: 10% when it is set up, then 9.8% withholding tax on movable income after 3 years. Total cost 18% against 30% for a standard dividend. See SRL dividends.
[05] Choice of business vehicle
A fully electric car in a company = still 100% deductible in 2026 (vs 0% for combustion-engine cars). Low benefit in kind. See company car.
The 2026 tax calendar
Four deadlines shape the year of a self-employed person in Belgium: the VAT return (monthly or quarterly), advance tax payments (4 quarters), the personal income tax return (until October online with specific income) and the NISSE contribution adjustments (Q4 of year N+2 on the income of year N).
- 20 January · 20 April · 20 July · 20 October 2026, quarterly VAT return and payment (quarterly scheme).
- 10 April · 10 July · 10 October · 20 December 2026, advance tax payments (reducing the surcharge applied when no payments are made).
- 31 October 2026, personal income tax return (2025 income) online via MyMinfin for a return with specific income (business profits, professional profits, director's remuneration). On paper, the deadline was 30 June 2026. Details in our article on the tax return deadline.
- Q4 2026, NISSE social security contribution adjustment for the 2024 tax year (final income).
Common mistakes to avoid
Three mistakes come up often in the tax files of the self-employed in Belgium: underestimating social security contributions (provisional calculation vs N+2 adjustment), forgetting advance tax payments (statutory surcharge of ~6% on the balance due), and choosing the wrong company vehicle (a combustion-engine car with a high benefit in kind and 0% deductibility from 2026).

Taxation FAQ
Frequently asked questions about taxation for the self-employed in Belgium
A self-employed person working in their own name pays personal income tax (IPP/PB) on a progressive scale of 25%, 40%, 45% and 50%. The 50% marginal rate applies above around €49,840 of net taxable income, to which the municipal surcharges (≈ 7.5%) are added, bringing the effective marginal rate to around 53.75%.
The statutory flat rate is calculated automatically on a sliding scale (30%, then 11%, 3%, 0%), capped at around €6,070. Above around €15,000 of actual expenses a year (supporting documents required), switching to actual expenses becomes worthwhile. They are declared in the "business expenses" annex on Tax-on-web.
The trade-off between working in your own name and an SRL/BV typically tips between €60,000 and €80,000 of net annual income. A company gives access to corporate income tax at 20% (SME, subject to conditions) or 25%, against a 50% marginal personal income tax rate, but it adds costs (accountant, filings with the Crossroads Bank for Enterprises (CBE), administration) and makes taking cash out via dividends more complex.
All expenses directly linked to the activity: office (rent or a share of your home), vehicle, phone/internet (business share), continuing training, professional insurance (liability, income protection), accountant's fees, NISSE social security contributions, PLCI/VAPZ premiums, equipment purchases, professional books and subscriptions. The key rule: supporting documents (invoices) and a direct link to the activity.
The standard Belgian VAT rate is 21%. Three reduced rates exist alongside it: 6% (food, books, medicines, certain property works), 12% (social housing, on-site restaurant meals excluding drinks), 0% (intra-EU exports). Below €25,000 of turnover excluding VAT, the small business exemption means you do not charge or deduct VAT.
For an IPC premium to be tax-deductible for the company, the total pension (statutory + supplementary) must not exceed 80% of the director's last normal gross annual remuneration. This rule therefore caps the total of PLCI + IPC + group insurance premiums and is a condition for deduction from corporate income tax.
The standard withholding tax on movable income is 30%. The VVPRbis regime lowers this rate to 18% (15% until 30 June 2026) for dividends on cash contributions to SMEs (registered shares, fully paid up, from the 3rd financial year). The liquidation reserve brings it down to around 15% effective if the profit is left in reserve for 5 years before distribution.
Since 2026, the deductibility of combustion-engine cars bought by the company has fallen to 0% (law of 25 November 2021 on greening the tax treatment of mobility). Only fully electric cars remain fully deductible, with a gradual sliding scale from 2027 (95%, 90%, 82.5%, 75%, 67.5%).
Annual BIK = catalogue value × [5.5% + (actual CO₂ − reference CO₂) × 0.1%] × 6/7 × age coefficient. The 2026 statutory minimum is around €1,690 a year. The 2026 reference CO₂ figures are 58 g/km for diesel and 70 g/km for petrol. The age coefficient falls from 100% to 70% after 60 months.

How does taxation work for the self-employed in Belgium?
Taxation for the self-employed in Belgium rests on two regimes depending on your status: if you work in your own name (as a natural person), you pay personal income tax on your net profit (turnover minus expenses) on a progressive scale from 25% to 50%; if you work through an SRL/BV, the company first pays corporate income tax (20% SME rate or 25%), then you are taxed yourself on your remuneration (personal income tax) and/or on dividends (withholding tax on movable income).
On top of this come NISSE social security contributions (≈ 20.5% of net income, paid via the National Institute for the Social Security of the Self-employed, INASTI/RSVZ) and VAT (21% standard rate, except under the small business exemption below €25,000 excluding VAT). Understanding how personal income tax, corporate income tax, contributions, VAT and withholding tax on movable income fit together is the basis of any optimisation.
