Personal income tax, Portugal vs Denmark: contribution, brackets, ceiling

Denmark in 2026, layer by layer

1. Labour market contribution: 8 % of salary and business income, before anything else.
2. Personal allowance: DKK 54 100 free of income tax.
3. Bottom-bracket tax 12,01 % plus municipal tax (set by each municipality, about 25 % on average) on all taxable income.
4. Middle-bracket tax 7,5 % on personal income above DKK 641 200 (after the contribution).
5. Top-bracket tax 7,5 % above DKK 777 900.
6. Additional top-bracket tax 5 % above DKK 2 592 700.
7. Tax ceiling 44,57 % on the ordinary layers, so the marginal rate reaches about 52 % with the top bracket and 57 % with the additional one, plus the 8 %.

Share income (dividends and gains) is taxed separately at 27 % up to DKK 79 400 and 42 % above. Interest and other capital income join ordinary income.

Portugal in 2026

11 % social contributions on the whole salary; then the specific deduction (4 587 € or the contributions if higher); then nine brackets from 12,5 % (to 8 342 €) to 48 % (above 86 634 €), with a solidarity surcharge of 2,5 % above 80 000 € and 5 % above 250 000 €. Dividends, interest and gains at 28 % flat by default. Couples may file jointly and split.

• 8 % + about 37 % on a Danish salary from the first krone above the allowance; 11 % + 12,5–48 % in Portugal
• Middle and top brackets from DKK 641 200 and 777 900 (about 86 000 € and 104 000 €); Portugal's 48 % from 86 634 €
• Ceiling in Denmark; none in Portugal
• 27 / 42 % vs 28 % on dividends and share gains

Worked examples (single employee)

Danish figures use the 8 % contribution, the DKK 54 100 allowance and 37 % (bottom plus an average municipal rate) before the employment deduction and other allowances that lower them by a few points; Portuguese figures use the tariff after the 11 % contributions, before personal credits, at 7,46 DKK per euro. Portugal is lighter on modest and middle salaries; Denmark’s ceiling makes it lighter above about 90 000 €.

Where the systems differ

• What the contribution buys. Denmark’s 8 % is a tax; health, pensions and unemployment are financed from general taxation, and unemployment insurance is voluntary (A-kasse). Portugal’s 11 % funds a contributory pension, sickness and unemployment cover.
• Capital income. Denmark’s 27 % / 42 % share tax against Portugal’s flat 28 %, with Portugal excluding 10 %, 20 % or 30 % of gains on listed securities after two, five or eight years and exempting crypto after a year.
• Pensions. Danish pensions of a Portuguese resident stay taxable in Denmark under the treaty; Portugal taxes them too and credits the Danish tax. A pension taxed at 37 % in Denmark and at 25 % in Portugal costs 37 %.
• Couples. Portugal’s splitting against Denmark’s individual taxation with a transferable allowance — Portugal is markedly lighter for a one-earner couple.
• Property. Denmark’s property value tax and land tax against Portugal’s IMI on a formula value.
