Portugal vs Norway tax in 2026: what a Norwegian in Portugal stops paying

Residence: Norway’s three-year shadow

Norway keeps a person tax-resident until they have been abroad three full years without spending more than 61 days a year in Norway and without a home there (shorter for people resident less than ten years). Until then, Norway taxes worldwide income and wealth — unless the treaty makes you resident of Portugal, which the Norwegian administration accepts on a Portuguese certificate of residence issued under the treaty. Portugal’s own test is 183 days in a twelve-month window or a habitual home (IRS Code, art. 16.º).

The Norwegian rulings on NHR residents are the warning: people taxed in Portugal on a limited basis were held not to be treaty-resident here, and Norway taxed everything. Ordinary Portuguese residence, with worldwide taxation, satisfies article 4.

• 22 % + bracket tax up to 17,8 % + 7,6 % — Norway's layers; 12,5 % to 48 % + 11 % in Portugal
• 1,0 % to 1,1 % Norwegian wealth tax above NOK 1,9 million; none in Portugal
• Private-sector pensions: Portugal only; basic NIS pension and public-sector pensions: Norway keeps taxing at 15 %
• NOK 3 million of latent gains free of exit tax; the rest payable within 12 years

Income tax, side by side

A Norwegian on NOK 900 000 (about 77 000 €) pays roughly 29 % in Norway after the minimum and personal deductions; in Portugal about 22 000 € of IRS plus 8 500 € of contributions, 40 % — Portugal is heavier on high salaries because Norway’s flat 22 % base and modest bracket tax beat Portugal’s 44,6 % band. On pensions, dividends and wealth the picture reverses: no wealth tax, 28 % instead of 37,84 %, and joint filing for couples. The social security and VAT page covers the contributions and the 25 % VAT.

The 2011 convention, as Skatteetaten applies it

The Norwegian tax administration publishes the list for Portugal:

Exempt in Norway (taxable in Portugal only): pensions and disability benefits linked to previous private-sector employment — supplementary NIS pensions paid by NAV, occupational pensions, company-paid pensions — and public-sector pensions when the recipient is a Portuguese citizen.

Taxable in Norway at 15 % withholding: the basic pension of the National Insurance Scheme, NIS disability benefits, public-sector pensions of non-Portuguese citizens, pensions linked to previous business activity, private pensions not linked to employment, annuities, war pensions. Portugal taxes these too and credits the Norwegian tax.

Exemption requires a certificate of residence under the treaty from Finanças and an application for a tax-deduction card with a lower rate. Dividends: 5 % at source for a company holding at least 10 % for twelve months, 15 % otherwise; interest and royalties 10 %; property where it stands; gains on shares in the residence state — after the exit tax. The treaty page reads the articles.

Leaving Norway: the exit tax

For moves from 20 March 2024, latent gains on shares, funds, options and similar assets — including foreign pension accounts treated as investments — are taxed on departure above a NOK 3 million basic deduction, with a choice between paying at once, in instalments over twelve years, or deferring the whole amount for twelve years; the liability lapses if you return within that period. Moves within the EEA need no security. Portugal then taxes gains from the original cost at 28 % on the real sale, with no credit for the Norwegian exit tax. Share savings accounts (ASK) and unit-linked policies are outside the exit tax but inside Portuguese tax on their income.

Companies and VAT

Norway: corporate tax 22 %, VAT 25 % (15 % on food, 12 % on transport, hotels and culture). Portugal: 19 % in 2026 (17 % from 2028), 15 % on the first 50 000 € for SMEs, VAT 23 / 13 / 6 %. See corporate tax.

Property and inheritance

Buying in Portugal: IMT by bracket (7,5 % flat while you are still non-resident since 25 May 2026, refundable within two years of becoming resident) plus 0,8 % stamp duty; IMI 0,3–0,45 % of the tax value; AIMI above 600 000 €. Norway abolished inheritance tax in 2014; Portugal charges 10 % stamp duty with spouses, children and parents exempt. A Norwegian home kept after the move is Norwegian-taxed on rent (art. 6) and, while Norwegian residence lasts, counted for wealth tax.

Special regimes

NHR closed on 1 January 2024. IFICI gives 20 % for ten years on Portuguese income from listed activities and exempts foreign income with progression; pensions are excluded — which is what makes a Portuguese resident “liable to tax” for the treaty and unlocks the Norwegian exemptions above.
