How the calculation works
- VAT is collected for the State and paid over: it passes through your account without being yours.
- The salary is a deductible expense for the company. On it you pay your self-employed social contributions: 20.5% up to €75,024.54 of income, 14.16% up to €110,562.42, nothing above (2026 scale).
- Personal income tax is calculated after contributions and a 3% flat-rate expense allowance (maximum €3,200): 25% up to €16,720, 40% up to €29,510, 45% up to €51,070 and 50% above, with a tax-free allowance of €11,180, then municipal tax.
- Corporate tax applies to the remaining profit: 25%, or 20% on the first €100,000 for an SME that meets the conditions.
- What is left belongs to the company. To take it out, more tax is due: see Investing through a company or as an individual?
What the simulator does not do
It is an estimate for a single director with no dependent children who has completed their first three years as self-employed. It does not take into account:
- personal tax reductions (children, pension savings, service vouchers…) or a couple's situation;
- benefits in kind (car, housing, computer) or the employer's own expense reimbursements;
- the time lag of social contributions, first paid on a provisional basis and adjusted later;
- VAT recovered on your purchases, carried-forward losses or notional interest.
Tax and contribution scales change every year. Have your salary and company structure checked by an accountant.

3 questions to check what you remember. Click an answer: the explanation appears straight away.
Question 1 of 3Why is VAT not a cost for the company?
The VAT you charge the customer passes through your account and is paid over to the State.
Question 2 of 3An SME pays a €30,000 salary for €80,000 of taxable profit, after its first 4 financial years. Which corporate tax rate?
The salary is below €50,000 and below the profit: the reduced rate is lost.
Question 3 of 3Which form of pay builds your statutory pension?
Only pay subject to social contributions builds statutory pension rights.
Frequently asked questions
How much do I keep from €100 invoiced through a company?
It depends mainly on your salary and expenses. With €100,000 of turnover, €10,000 of expenses and a €60,000 gross salary, you keep about €34 net per €100 invoiced, and €24 stays in the company, before the tax due to take it out.
Do I have to pay myself at least €50,000?
To keep the reduced 20% corporate tax rate, an SME must pay at least one director €50,000 gross a year, or at least the amount of its taxable profit, except during its first four financial years. Raising your salary to reach it is not always worthwhile.
Does the simulator work for a sole trader without a company?
No. As an individual, the whole profit is subject to progressive tax and social contributions; there is no corporate tax and no money left in a company.
