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.
Tax scale for sole proprietorship — a comprehensive guide
The progressive tax scale (skala podatkowa) is the default taxation method in Poland, available to both employees and sole proprietors. For B2B entrepreneurs, it offers a tax-free allowance and the ability to use numerous deductions, but comes with a 32% rate on higher income. Here is everything you need to know about using the tax scale for your business in 2026.
How Does the Tax Scale Work in 2026?
Under the tax scale, your business income (revenue minus tax-deductible costs minus ZUS social contributions) is taxed progressively. The first 30,000 PLN of annual income is tax-free thanks to the tax-reducing amount of 3,600 PLN (12% of 30,000 PLN). Income from 30,001 PLN to 120,000 PLN is taxed at 12%, and everything above 120,000 PLN is taxed at 32%. As a sole proprietor, you pay monthly or quarterly PIT advance payments based on cumulative income. The health insurance contribution is 9% of your income (minimum 432.54 PLN based on the minimum wage of 4,806 PLN) and is not deductible from tax or income.
Tax Brackets: 12% and 32%
Poland's two-bracket system creates a clear threshold at 120,000 PLN of annual income. Below this amount, you pay 12% PIT minus the tax-reducing amount (effectively making income up to 30,000 PLN tax-free). Once your income exceeds 120,000 PLN, you pay 10,800 PLN (12% on the 90,000 PLN taxable portion of the first bracket) plus 32% on every zloty above 120,000 PLN. For example, an entrepreneur with annual income of 180,000 PLN pays: 10,800 PLN + 32% of 60,000 PLN = 30,000 PLN in PIT. The effective tax rate rises as income grows, reaching approximately 25% at 300,000 PLN of annual income.
Tax-Free Amount: 30,000 PLN
The 30,000 PLN tax-free allowance is one of the biggest advantages of the tax scale over flat tax and lump-sum tax (neither of which offers this benefit). In practical terms, this means 3,600 PLN less tax per year (30,000 PLN x 12%). For a sole proprietor earning 100,000 PLN annually, this reduces the effective tax rate from 12% to about 8.4%. The allowance is applied automatically through the monthly tax-reducing amount of 300 PLN subtracted from each PIT advance payment. If you also earn income from employment, make sure you do not apply the tax-reducing amount twice.
Who Benefits Most from Tax Scale?
The tax scale is generally optimal for sole proprietors with annual income below 120,000 PLN, especially those who can leverage deductions such as the child tax credit (up to 2,700 PLN per child), joint filing with a spouse, internet costs deduction, IKZE retirement contributions, or the thermal modernization relief. It is also the best choice for entrepreneurs whose spouse has little or no income, as joint filing effectively doubles the 12% bracket to 240,000 PLN. Conversely, single high earners above 120,000 PLN typically save money by switching to flat tax (19%) or lump-sum tax.
Tax Scale vs Other Tax Forms
Compared to the 19% flat tax, the tax scale wins for income below ~120,000 PLN but loses above that due to the 32% rate plus 9% health insurance. The flat tax charges only 4.9% health insurance (partially deductible up to 14,100 PLN), making it more attractive at higher income levels. Lump-sum tax can be even cheaper for low-cost businesses (like IT at 12% of revenue), but it does not allow deducting business costs and offers no tax-free amount or joint filing. The optimal choice depends on your specific income level, business costs, and personal situation. You can switch tax forms by notifying the tax office by February 20th of the tax year.

When is the progressive tax scale worth choosing?
