Portugal vs Denmark tax in 2026: what a Dane in Portugal keeps paying to Denmark

Residence: a home or six months

Denmark makes you fully liable when you have a home available in Denmark or stay there six consecutive months; full liability ends when the home is given up. Portugal starts residence after 183 days in a twelve-month window or from the day you keep a home that looks like a habitual residence (IRS Code, art. 16.º). The convention breaks a tie by permanent home, centre of vital interests, habitual abode and nationality. A Dane who keeps the house in Aarhus and lets it on a lease of less than three years keeps a Danish home — the three-year lease is the test Danish practice applies.

• 8 % + 12,01 % + municipal tax — the Danish base; middle and top brackets add 7,5 % each from DKK 641 200 and 777 900, and 5 % more above DKK 2,59 million
• 12,5 % to 48 % in Portugal, with 11 % social contributions instead of Denmark's tax-financed system
• Danish pensions stay Danish under article 18 — the residence state credits
• 10 % / 10 % / 10 % treaty ceilings on dividends, interest, royalties; 27 % / 42 % Danish share tax against 28 %

Income tax, side by side

A Dane on 400 000 DKK (about 53 600 €) pays roughly 37 % all-in in Denmark; in Portugal the same salary costs about 13 000 € of IRS plus 5 900 € of contributions, 35 %. Above 800 000 DKK the Danish ceiling matters and Portugal’s uncapped 11 % narrows its lead. The personal income page works the figures.

The 2000 convention

• Pensions (art. 18): payments under Danish social security legislation (folkepension, ATP) may be taxed in Denmark; private and occupational pensions are taxable in the residence state unless the contributions were deducted from taxable income in Denmark or paid by an employer without being taxed — which describes almost every Danish pension scheme — in which case Denmark may tax them. In practice every Danish pension of a Portuguese resident remains taxable in Denmark, Portugal taxes it too as the residence state, and Portugal credits the Danish tax up to its own (art. 81.º).
• Government pensions (art. 19): Denmark only.
• Dividends, interest, royalties: 10 % at source. Denmark’s domestic 27 % on dividends falls to 10 % for a Portuguese resident on a reclaim; Portugal’s 28 % falls to 10 % for a Dane.
• Property: where it stands. Shares: residence state — with Denmark’s exit tax applied first.
• Relief: credit in both countries. The treaty page reads the articles.

Leaving Denmark: the exit tax

Shares and securities worth DKK 100 000 or more on the day you leave are deemed sold; the gain is taxed at 27 % / 42 %. You can defer by request (form 04.065 or in E-tax by 1 July of the following year), without security for a move within the EU, reporting the portfolio yearly; the deferred tax falls due as you sell or receive dividends. Portugal then taxes gains from the original cost at 28 % with no credit for the Danish exit tax on the earlier deemed sale. Danish pension savings and property are outside the exit tax.

Companies and VAT

Denmark: corporation tax 22 %, VAT 25 % with no reduced rate. Portugal: IRC 19 % in 2026 (17 % from 2028) with 15 % on the first 50 000 € for SMEs, VAT 23 / 13 / 6 %. See corporate tax for Danish companies.

Property and inheritance

Buying in Portugal: IMT by bracket (7,5 % flat while you are still non-resident since 25 May 2026, refundable when you become resident within two years) plus 0,8 % stamp duty; IMI 0,3–0,45 % of the tax value yearly; AIMI above 600 000 €. Inheritance: Portugal charges 10 % stamp duty with spouses, children and parents exempt; Danish estate duty (boafgift, 15 % for close family, 36,25 % for others) applies to the estate of a person domiciled in Denmark and to Danish property.

Special regimes

NHR closed on 1 January 2024; Danish pensions never benefited from it in full because the treaty let Denmark tax them anyway. IFICI gives 20 % for ten years on Portuguese income from listed activities and exempts foreign income with progression for people not resident here in the previous five years — a Dane hired by a certified start-up or a qualifying exporter keeps Danish dividends at 10 % Danish tax and nothing Portuguese. Pensions remain outside.
