Norway is consistently among the world's highest-taxed countries, but its tax system is more structured than the headline rates suggest. The combination of a 22% base tax and the progressive trinnskatt (step tax) produces an effective top rate of around 47.4% — but the actual burden depends heavily on income level, deductions, and whether you qualify for Norway's simplified PAYE scheme designed for new arrivals.
This guide covers how Norway's dual tax system works, the PAYE scheme for simplicity, social security contributions, how tax residency is determined, and what US citizens need to know about their ongoing US filing obligations.
According to the Skatteetaten (Norwegian Tax Administration), Norwegian income tax operates on two parallel tracks applied to the same income:
A flat 22% is applied to all taxable income (alminnelig inntekt — general income). This covers employment income, business income, capital income (dividends, interest, capital gains), and pension income. Standard deductions are applied before calculating alminnelig inntekt, including a personal allowance (personfradrag) of approximately 88,250 NOK and an employment deduction (minstefradrag) of up to 104,450 NOK.
The trinnskatt is an additional progressive tax applied on top of fellesskatt, calculated on gross personal income (personinntekt) — a broader measure that does not benefit from most deductions. The 2026 trinnskatt steps are approximately:
| Income (NOK) | Step Tax Rate |
|---|---|
| Under 208,305 | 0% |
| 208,305–292,850 | 1.7% |
| 292,851–670,000 | 4.0% |
| 670,001–937,900 | 13.6% |
| 937,901–1,350,000 | 16.6% |
| Above 1,350,000 | 17.6% |
Note: Norway adjusts trinnskatt thresholds annually. Verify current thresholds at Skatteetaten.no.
Additionally, employees pay 7.8% trygdeavgift (national insurance) on employment income. Self-employed pay 11.0%. The combined burden at high income levels (22% fellesskatt + 17.6% trinnskatt + 7.8% trygdeavgift) reaches approximately 47.4%.
Norway operates a PAYE (Pay As You Earn) scheme specifically designed for foreign workers arriving in Norway. Under the PAYE scheme, your entire tax and national insurance obligation is settled through a single flat deduction of 25% from your gross salary — no annual return required.
The PAYE scheme is available to:
You can use PAYE for your first two income years in Norway. After that, you transition to the standard system and must file an annual return.
At lower income levels (below approximately 600,000 NOK), the standard system with deductions often produces a lower effective tax rate than the 25% PAYE flat. At higher income levels, PAYE may be simpler and comparable. The trygdeavgift (7.8%) is included within the PAYE 25% — it is not an additional deduction.
One key difference: under PAYE, you cannot claim deductions (mortgage interest, home office, etc.). If you have significant deductions available, the standard system is likely better. Consult with a Norwegian tax adviser to compare your specific situation.
Norway determines tax residency on two timescales:
You become a Norwegian tax resident if you spend 183 days in Norway within any 12-month period. Norway uses a rolling 12-month window (not a calendar year), making it stricter than some countries. Partial days count as full days.
Once you have spent 270 days in Norway within any 36-month period, you are subject to full Norwegian tax residency and worldwide income taxation with no ability to claim non-resident status for treaty purposes without strong evidence of residency elsewhere.
To cease Norwegian tax residency, you must: leave Norway and demonstrate you have established residency elsewhere. Norwegian residency does not end automatically when you leave — you must notify the tax authorities and demonstrate you have a permanent home abroad and no longer maintain strong Norwegian ties. For the first 1–3 years after departure, Norway may still claim residency unless you have a firm establishment abroad.
Norway has a specific exit rule: if you move to a low-tax country, Norwegian residency is maintained for an additional period unless you can demonstrate real economic ties to the new country.
Norwegian social security (trygd) provides extensive benefits including healthcare (free at point of use), parental leave, unemployment insurance, and pension. Contributions are:
The employer contribution (arbeidsgiveravgift) is a major component of Norway's total labour cost. At the standard 14.1% rate, the total cost of employing someone at 700,000 NOK is approximately 798,700 NOK.
Once enrolled in the Norwegian National Insurance Scheme (Folketrygden), expats are entitled to the same benefits as Norwegian citizens, including:
Norway pre-fills most employees' tax returns (skattemelding) using data from employers and banks. The process:
If you are on the PAYE scheme, you do not need to file an annual return — your 25% deduction is the final settlement. You will receive an annual statement confirming the amounts deducted.
Employees who arrived or departed Norway during the year file as partial-year residents and must declare worldwide income for the resident period.
US citizens working in Norway must still file annual US federal tax returns. Norway's high tax rates generally mean the Foreign Tax Credit eliminates most or all US tax liability on Norwegian employment income — but filing is still required.

Transfer Money From Norway →The trinnskatt is a progressive step tax applied on top of Norway's base 22% flat tax. It is calculated on gross personal income (before most deductions) and ranges from 1.7% at low-mid incomes to 17.6% above approximately 1,350,000 NOK (~€120,000). Combined with the 22% base tax and 7.8% national insurance, the effective top rate is approximately 47.4%.
The PAYE scheme lets new foreign workers in Norway pay a flat 25% of gross salary as their entire tax and national insurance obligation — no annual return required. It's available for your first two income years. At lower incomes (below ~600,000 NOK), the standard system with deductions often produces a lower rate. At higher incomes, PAYE is broadly comparable and much simpler. Assess with a Norwegian tax adviser.
You become a Norwegian tax resident when you spend 183 days in Norway within any rolling 12-month period. Note: Norway uses a rolling 12-month window, not a calendar year. After 270 days within 36 months, full residency applies. Registering with a Norwegian municipality (folkeregisteret) also triggers tax residency.
At approximately 900,000 NOK (around €78,000), the combined rate is roughly: 22% fellesskatt on taxable income (after deductions) + 16.6% trinnskatt on gross income at that bracket + 7.8% trygdeavgift. Effective total tax rate is approximately 37–42% depending on deductions claimed. Use the Norway Tax Calculator for a personalised estimate.
Yes. Once enrolled in the Norwegian National Insurance Scheme (Folketrygden) — which happens automatically upon taking up employment and paying trygdeavgift — expats have the same access to the public health system as Norwegian citizens. GP access via the fastlege (regular GP) system and hospital treatment are free or at minimal cost. A GP registration fee (fastlegeskifte) may apply initially.
In most cases, yes. Norway's effective income tax rate (37–47%) exceeds the US rate on most income levels, so Foreign Tax Credits from Norwegian taxes paid typically eliminate US tax liability on that same income. However, you must still file Form 1040 annually. The Norway-US tax treaty provides additional protection. Consult a US expat tax specialist to confirm your specific situation.
The employer arbeidsgiveravgift varies by region: the standard rate in Oslo and most urban areas is 14.1% of gross salary. This is a significant additional cost on top of gross salary. Some northern Norwegian zones (Troms, Finnmark) attract 0% employer NI to incentivise employment — a meaningful consideration for remote workers whose employer is based in those areas.
