Tax Scale vs other tax forms

The tax scale (general principles) is the default tax form in Poland. An entrepreneur can change it to flat tax or lump-sum tax by submitting a declaration by the 20th of the month following the month of earning the first revenue, or by February 20th of the tax year.

Advantages of the tax scale

The tax-free amount of 30,000 zł means you pay no tax on income up to this amount. You can file jointly with your spouse, use deductions (for children, internet, thermal modernization) and deduct donations. This is the most beneficial form for annual income below 120,000 zł.

Disadvantages of the tax scale

For income above 120,000 zł per year, the rate increases to 32%. Health insurance contribution is 9% of income and is not deductible, which at high incomes represents a significant burden. In such cases, it is worth considering flat tax (19%) or lump-sum tax.
