Income Tax Brackets & Reform Simulator
Compare current tax brackets with proposed new tax reforms (including the new 24% intermediate rate, threshold adjustments, and increased personal allowances).
Current Tax Scale (2026)
Personal allowance: 30k PLN | 12% up to 120k | 32% above 120k
Proposed 3-Tier Reform (2027)
12% up to 130k | New 24% tier (130k-150k) | 32% above 150k
Scenario: 60k Allowance
60,000 PLN tax-free allowance | 12% up to 120k | 32% above 120k
Scenario: 180k Threshold
30,000 PLN allowance | 12% up to 180k | 32% above 180k
How Does the 3-Tier Progressive Income Tax Reform Work?
Progressive tax systems use marginal tax brackets where higher rates only apply to income earned above specific thresholds. The proposed reform introduces an intermediate 24% bracket to eliminate the steep cliff between 12% and 32%.
Tax Bracket Reforms in Other Countries
🇩🇪 Niemcy: Kalte Progression
Niemcy corocznie waloryzują progi podatkowe i kwotę wolną (Grundfreibetrag), aby inflacja nie wpychała pracowników w wyższe progi bez realnego wzrostu płac.
🇬🇧 Wielka Brytania: Fiscal Drag
W Anglii kwota wolna (£12,570) jest zamrożona do 2031 r., co generuje tzw. ukryty podatek. W Szkocji wprowadzono aż 6 elastycznych progów podatkowych (19%–48%).
🇺🇸 USA: Koniec ulg TCJA
W USA wygasają stawki podatkowe z reformy TCJA 2017. Bez przedłużenia przez Kongres, stawki powrócą do wyższych poziomów sprzed 2018 roku.
About Calculator
The Income Tax Brackets & Reform Calculator models progressive taxation structures, bracket creep, and proposed tax reform scenarios. It compares standard 2-tier tax scales with proposed 3-tier models introducing intermediate tax brackets and adjusted tax-free allowances.
Marginal tax rates apply only to income within specific tranches. When a new bracket (such as a 24% intermediate rate) is introduced between existing 12% and 32% thresholds, it eliminates steep marginal cliffs and protects middle-income purchasing power.
Frequently Asked Questions (FAQ)
What is bracket creep (fiscal drag)?
Bracket creep occurs when inflation increases nominal earnings, pushing taxpayers into higher tax brackets without any real increase in purchasing power.
How does the proposed 2027 3-tier tax scale work?
Income up to 30,000 PLN is tax-free. Earnings from 30k to 130k are taxed at 12%, earnings from 130k to 150k at 24%, and earnings above 150k at 32%.
What is the difference between marginal and effective tax rate?
The marginal rate is the tax paid on your last earned currency unit. The effective tax rate is total tax paid divided by total income.
