How much to set aside for taxes
Enter your average monthly income. We work out how much of it to put aside each month for income tax and a sole trader’s contributions.
How the calculation works
From an average month we work out the whole year: the contributions to the social and health insurers, paid every month, and the income tax, paid after the year ends together with the tax return. We spread the tax over 12 months so the money is ready when it is due.
Contributions follow income with a delay: each July they are adjusted to the previous year’s income, so when your income grows they go up from July. For the exact figure, use the contributions calculator

Frequently asked questions
When is income tax paid?
The tax for a year is due by the deadline of the tax return, usually 31 March of the following year. If your tax for the previous year was over €5,000, you pay advances during the year: quarterly, or monthly above €16,600 (§34 of the Income Tax Act).
What if my income grows during the year?
Set aside according to the higher income. Tax is computed on the whole year, and your contributions go up from July of the following year according to what you earned.
What if I am a VAT payer?
You pay the VAT on your invoices separately, monthly or quarterly, and this calculation does not include it: enter your income without VAT. A VAT payer for the whole year also cannot claim flat-rate expenses.
Where should I keep the money?
Simplest is a separate account: when a customer pays you, move the calculated share there straight away, so the money is still there when the tax is due.
