If you’re a tax resident in Sweden, the government cordially reminds you that your income is no longer yours, but a global collaborative effort. Whether it's a rental property in Italy or a side hustle in Seoul, Skatteverket (the Swedish Tax Agency) views every cent on Earth as potential Swedish revenue. They graciously provide "tax treaties" to prevent double taxation — a generous administrative maze that ensures you don't lose your money twice.
foreign income tax

Many internationals who move here assume that their tax obligations are limited to their local salary, which is actually a common misconception.
Becoming a tax resident in Sweden triggers a far broader set of requirements under its worldwide taxation model, which requires disclosure of your total global income — regardless of where that money was generated.
Understanding this obligation is essential to avoiding unexpected tax liabilities and ensuring compliance during annual reporting.
If you are a tax resident in Sweden, you are taxed on your global income. This means you must report and potentially pay tax on money earned anywhere in the world, including:
- salary from a foreign employer
- dividends from foreign stocks
- rental income from property abroad
- capital gains
- business income
- pensions
Sweden may consider you fully tax liable (obegränsat skattskyldig) if you:
- live in Sweden
- stay in Sweden continuously for 6 months or more
- have significant ties to Sweden after moving abroad
Your circumstances determine which rules apply. Once you become fully tax liable, Sweden generally expects you to declare your worldwide income, including income earned or taxed in another country.
This is where declaring income and paying tax become two separate questions.
Being fully tax liable doesn't necessarily mean you will pay Swedish tax on every item of foreign income. The outcome depends on the type of income, the applicable tax rules and any tax treaty between Sweden and the country where the income arose.
1
declare the income
You may need to report foreign income on your Swedish tax return, even if tax has already been paid abroad.
2
determine whether sweden can tax it
Swedish domestic law and any applicable tax treaty determine whether Sweden has the right to tax that particular income.
3
account for foreign tax
If both countries can tax the income, relief may be available to prevent double taxation. This can involve a foreign tax credit (avräkning av utländsk skatt), an exemption or another treaty mechanism. A credit is generally subject to limits and conditions, so you may not always recover the full amount of foreign tax paid.
Reporting foreign income does not automatically mean paying tax on it twice. You must first establish what needs to be declared, which country has the right to tax it and what relief is available.
1
employment income
This is subject to municipal tax (typically 30–34%) and a state tax of 20% on income exceeding the threshold (SEK 643,000 for 2026).
2
capital income
Investments, dividends, and capital gains are generally taxed at a flat rate of 30%.
the situation
You move to Sweden. You have a Swedish salary, a US stock portfolio, and rental income from Spain.
- Swedish salary: SEK 500,000
- US dividends: SEK 100,000 (assume 15% US withholding tax = SEK 15,000 paid)
- Spanish rental income: SEK 120,000 (assume 19% Spanish tax = SEK 22,800 paid)
- Total taxable income (reported to Skatteverket): SEK 720,000
the calculation
- Sweden calculates tax on SEK 720,000 (let’s assume a 35% average tax rate for this example = SEK 252,000 total tax due)
- Apply Foreign Tax Credits (AVR):
- You subtract the tax already paid abroad: 252,000 (Swedish Tax) – 15,000 (US) – 22,800 (Spain) = SEK 214,200 remaining tax to pay to Sweden
- The "gap" reality:
- If Sweden's tax rate on that specific income is higher than the foreign country's rate, you pay the difference to Skatteverket
- If Sweden's tax rate is lower (rarely the case), you generally do not get a refund from Skatteverket for the extra tax you paid abroad. You are capped at the Swedish tax level
rule 1: the 6-month rule
- If you work abroad for a Swedish employer for at least 6 months and fulfill specific criteria regarding your time spent outside of Sweden, that income may be exempt from Swedish tax
rule 2: short-term workers (s.i.n.k.)
- If you are in Sweden for less than 6 months and qualify as a non-resident, you may pay the SINK tax — a flat rate of 25% — instead of standard progressive taxation
rule 3: tax treaties
- Sweden maintains bilateral agreements with many countries. These treaties determine which nation has the primary right to tax specific types of income

- Declare foreign income annually, even if it is not taxable in Sweden
- Convert everything to SEK using the exchange rate at the time of the transaction or the year-end average, depending on the asset type
- Figure out what tax rules apply to you, specifically: The final tax burden depends heavily on your residency status, the specific type of income, and the tax treaty in place with the source country
- Foreign trades: If you see your foreign trades pre-filled on your tax return, double-check your omkostnadsbelopp (acquisition cost) immediately. The tax agency may have the sales data, but they often lack the cost basis data, which could lead to you paying way more tax than you actually owe

do I really have to declare income if I’ve already paid tax on it in my home country?
Yes. Being a tax resident in Sweden means Skatteverket (the Swedish Tax Agency) wants to see the full picture of your global finances. You must declare the income, but you then use the 'foreign tax credit' process to ensure you aren't paying the same tax twice. Failing to report it — even if it's 'tax-neutral' — can trigger audits or penalties.
can I deduct losses on foreign investments if I lose money?
Generally, yes, but with limitations. You can deduct 70% of a loss on listed shares or funds, but these losses can usually only be offset against gains from the same type of assets (e.g., a stock loss against a stock gain). It’s not a 1:1 deduction against your salary, so keep meticulous records of your buying and selling prices.
what currency exchange rate should I use for my tax return?
You should use the official annual average exchange rate provided by the Swedish Central Bank (Riksbank) for the specific tax year. Do not use the exact rate from the day the money hit your account unless you have a specific reason to (like an isolated, large transaction). Using the Riksbank annual average is the standard, accepted method for most foreign income.
what if I move to sweden partway through the year?
You generally become a tax resident from the date you arrive and establish a 'home.' You are then responsible for declaring your worldwide income from that date forward. Income earned before you moved to Sweden is usually not subject to Swedish tax, but it is important to clearly document your move-in date with Skatteverket to avoid confusion.
is there an app or 'easy' way to do this if I have many foreign accounts?
Because Sweden is not connected to every foreign bank’s API, you will likely have to manually enter your foreign holdings into your Swedish tax return.
why do I see my foreign trades on my tax return?
Skatteverket is increasingly receiving data directly from international brokers, and you may see some trades or dividend information already populated in your return. However, do not assume this is complete or correct.
While the data might appear, it is your legal responsibility to ensure it is accurate. Foreign brokers often report information in a way that doesn't perfectly map to the Swedish K4 form (the form used for calculating capital gains/losses). You may still need to:
- verify the acquisition costs: The pre-filled data might be missing your original purchase price (especially if the asset was moved or bought years ago), which leads to an incorrect tax calculation
- check currency conversions: You must ensure the currency conversions were handled using the correct rates
- add missing items: The system may catch the "big" trades but miss smaller ones, dividends, or specific fees
