🇵🇱 Poland — Flat Tax Health Insurance Deduction in 2026

How does flat tax health insurance differ from the tax scale?

Under Poland's flat 19% tax (podatek liniowy), health insurance is 4.9% of taxable income — roughly half the tax scale's 9% rate. And unlike the tax scale, where health insurance isn't deductible at all, flat tax lets you deduct a portion of what you pay, capped at 14,100 PLN/year. And a minimum also applies. It was 314.96 PLN for January 2026 and is 432.54 PLN/month from February through December.

What do I give up to get the lower rate?

The 30,000 PLN tax-free allowance and any joint-filing benefit with a spouse — flat tax applies 19% from the first zloty of taxable income, with no 0% band at the bottom. You still deduct real, documented business expenses, same as the tax scale.

And at high income, "flat 19%" is not the whole bill, the separate 4% solidarity levy applies to the portion of the relevant annual base above 1,000,000 PLN.

When does flat tax actually beat the tax scale?

Roughly above 175,000 PLN/year in the zero-expense, full-ZUS scenario — below that, the tax scale's tax-free allowance keeps it cheaper despite the higher 9% health rate. Real business costs shift the crossover because both methods deduct them.
