Danes are often told the Portugal treaty is gone; it is not. It was Denmark's treaty with Spain that ended, not the one with Portugal. The Denmark-Portugal treaty is in force, but it is unusual: it lets Denmark keep taxing Danish pensions even after you move, so the planning is about credit relief and documentation rather than a clean exit. The sections below take the treaty, the pension rule, and the Danish exit charges in order. This is general guidance, not advice, and figures should be confirmed for your year.
Why Danish Movers to Portugal Face a Specific Corridor
Denmark kept its treaty with Portugal, so you are not exposed to uncapped double taxation the way a Swede is. But the Denmark-Portugal treaty lets Denmark keep the right to tax many Danish pensions, the occupational and private pensions built up with Danish tax relief, even when you live in Portugal. Portugal also taxes the pension as your country of residence, and because IFICI does not exempt pensions, the two overlap, relieved by a credit rather than by one country standing back.
On the way out, Denmark can charge an exit tax on certain assets and a separate charge on cashing in some pension schemes. So the corridor is: rely on the treaty, plan the pension where Denmark keeps a claim, and watch the Danish exit charges.
Denmark Kept Its Treaty with Portugal (Unlike Sweden)
It is worth stating plainly because the confusion is common: Denmark did not terminate its tax treaty with Portugal. The treaty signed in 2000 is in force. The Nordic treaty that ended over the pension dispute was Sweden's, and Denmark's own terminated treaty was the one with Spain, not Portugal.
Because the treaty is in force, relief works through it, but the direction depends on the income category. For pensions covered by the treaty's special Danish pension rule, Danish guidance describes Denmark reducing Danish tax by Portuguese tax. For other Danish-source income, Portugal may relieve the overlap through its foreign-tax credit. In every case, the credit only relieves tax you have actually paid and can document, so paperwork matters.
Pensions: Denmark Keeps the Taxing Right
This is the defining feature for Danish movers. The treaty's general rule taxes pensions in your country of residence, Portugal. But it lets Denmark keep taxing a Danish occupational or private pension where that pension was built up with Danish tax relief, which is typical of Danish workplace and rate-pension schemes. In practice, then, many Danish pensions remain taxable in Denmark under limited tax liability even after you become a Portuguese resident, while Portugal also taxes the same pension as a resident, and because IFICI does not exempt foreign pensions, at progressive rates.
What stops this being double taxation is the treaty relief mechanism, but for these Article 18 pension cases the Danish Tax Agency describes Denmark reducing Danish tax by Portuguese tax, not the other way around. The catch is documentation: the credit relieves only tax actually paid and evidenced in the other country, and a nil result in one country is treated as a deliberate benefit rather than a waiver, so keeping clear records of what each country has taxed is essential. A Danish public-service pension is taxable only in Denmark.
Ceasing Danish Tax Residency: the Exit Tax and Pension Afgift
Danish full tax liability generally rests on having a home available in Denmark, and it does not end until you genuinely give that up. A retained dwelling can keep you fully taxable in Denmark and create real dual taxation, while Danish guidance treats a holiday home used only for holidays differently. After departure you usually move to limited tax liability, under which Denmark still taxes Danish-source income, including Danish pensions.
Two Danish charges to plan for: an exit tax can treat gains on shares and certain other assets as realised on departure, broadly where you were fully taxable in Denmark for at least seven of the last ten years; and a separate charge can apply if you terminate or cash in certain capital or old-age pension schemes. On the other side, once full Danish liability ends you can usually apply to stop the Danish tax on pension-fund returns. Confirm the current rules for your specific schemes.
Danish Dividends and Property
Danish dividends to a non-resident are withheld at the high domestic rate, and the treaty rate is obtained by reclaim rather than automatically at source, so expect to file for the difference. Portugal then taxes the dividend as your resident income and credits the Danish tax. Danish real estate stays taxable in Denmark because that is where the property sits, with Portugal taxing the same income and giving relief. As with the pension, the discipline is documentation: claim the treaty rate, and record the Danish tax so Portugal gives the credit.
Coordinating Skat and Finanças
Keeping Danish pensions, shares, or property usually means Danish filings as a non-resident alongside Portuguese filing, with the treaty deciding who taxes what and which country gives relief. The work is planning the residency cessation and the exit charges, getting the pension and dividend treatment documented, and making both filings rely on the same facts so the credit is given for the right amount. A signed Position Memo gives you and any Danish adviser one position to file from.

Frequently Asked Questions
Did Denmark Terminate Its Tax Treaty with Portugal?
No. The Denmark-Portugal treaty is in force. The confusion comes from Sweden, which did terminate its Portugal treaty, and from Denmark's own terminated treaty with Spain. For Danes moving to Portugal, the treaty applies and relief is by credit.
Where Is My Danish Pension Taxed?
In many cases, both countries. The treaty's general rule is residence-taxation, but it lets Denmark keep taxing a Danish occupational or private pension built up with Danish tax relief, which is typical, while Portugal also taxes it as your country of residence because IFICI does not exempt pensions. Treaty relief prevents true double taxation; for Article 18 pension cases Danish guidance describes Denmark reducing Danish tax by Portuguese tax. A Danish public-service pension is taxable only in Denmark.
Do I Pay a Danish Exit Tax When I Leave?
You may. Denmark can treat gains on shares and certain assets as realised when your full tax liability ends, broadly where you were fully taxable in Denmark for at least seven of the last ten years, and a separate charge can apply to cashing in certain pension schemes. A retained Danish home can also keep you fully taxable. The position should be checked before departure.
Does IFICI Cover My Danish Pension?
No. IFICI, the regime that replaced NHR, does not exempt foreign pensions; Portugal taxes them at progressive rates. Because the treaty also lets Denmark tax some pensions at source, the planning is about getting the treaty relief and records right, not avoiding tax in one country.
How Is Double Taxation Relieved Between Denmark and Portugal?
By a treaty credit, so the same income is not taxed twice in full. For Danish pensions covered by the treaty's special Article 18 rule, Danish guidance describes Denmark reducing Danish tax by Portuguese tax. Other Danish-source income can have a different relief direction, including Portuguese foreign-tax credit. The credit only relieves tax actually paid and documented, so keeping records of what each country has taxed is essential to avoid an unrelieved overlap.
