# 🇵🇱 Poland — Can I Deduct Expenses Under Flat Tax in 2026?

2026-07-26 — Podnikio Team

Yes — Poland's flat 19% JDG tax lets you deduct real documented business expenses, exactly like the tax scale. Ryczałt is the one method that doesn't.

## Can I deduct real business expenses under Poland's flat tax?

Yes. Flat tax (*podatek liniowy*) lets you subtract **actual, documented costs incurred to earn, preserve, or secure business revenue**, and the 19% rate applies to the resulting income. But normal statutory exclusions and limits still apply — for example to private expenditure, representation, cars, depreciation, and transactions that do not meet the business-purpose test — so "legitimate" is not an unlimited category.

## How is this different from ryczałt?

**Ryczałt taxes gross revenue directly, with no expense deduction at all.** This is the single biggest structural difference between Poland's four JDG-adjacent options: tax scale and flat tax both deduct real costs; ryczałt doesn't, no matter how large your genuine expenses are.

## So when does that matter?

If you have significant deductible costs — subcontractors, equipment, software licenses — flat tax (or the tax scale) will usually beat ryczałt even at a low ryczałt rate, because ryczałt has no mechanism to reflect those costs at all. Ryczałt is most attractive specifically when your real costs are low relative to revenue.
