Norway taxes residents on a dual system: a 22% flat 'base tax' (fellesskatt) on all income, plus a progressive trinnskatt (step tax) reaching 17.8% at the highest band. Combined top effective rate is approximately 47.4%. New arrivals can use the simplified PAYE scheme β a flat 25% deduction covering income tax plus national insurance β for their first two years in Norway.

Introduction
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% β 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.
Section 01
How Norway's Tax System Works: Fellesskatt + Trinnskatt
According to the Skatteetaten (Norwegian Tax Administration), Norwegian income tax operates on two parallel tracks applied to the same income:
Track 1: Fellesskatt (General Tax / Base Tax)
A flat 22% is applied to all taxable income (alminnelig inntekt β 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 114,540 NOK and an employment deduction (minstefradrag) of 46% of wages, up to 95,700 NOK (2026).
Track 2: Trinnskatt (Step Tax / Bracket Tax)
The trinnskatt is an additional progressive tax applied on top of fellesskatt, calculated on gross personal income (personinntekt) β a broader measure that does not benefit from most deductions. The 2026 trinnskatt steps (Skatteetaten) are:

Note: Norway adjusts trinnskatt thresholds annually. Verify current thresholds at Skatteetaten.no.
National Insurance (Trygdeavgift)
Additionally, employees pay 7.6% trygdeavgift (national insurance) on employment income in 2026. Self-employed pay 10.8%. The combined marginal rate at high income levels (22% fellesskatt + 17.8% trinnskatt + 7.6% trygdeavgift) reaches 47.4%.
Section 02
The PAYE Scheme: Simplified Tax for New Arrivals
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 β no annual return required.
Who Can Use PAYE
The PAYE scheme is available to:
Foreign employees working in Norway for the first time
Employees who have not previously been Norwegian tax residents
Those who have been away from Norway for a continuous period (returning expats)
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.
PAYE vs Standard: Which Is Better?
At lower income levels (below approximately 670,000 NOK on 2026 rates), the standard system with deductions produces a lower effective tax rate than the 25% PAYE flat. Above that level, PAYE's flat 25% is usually cheaper as well as simpler. The trygdeavgift (7.6%) is included within the PAYE 25% β 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.
Section 03
Tax Residency in Norway
Norway determines tax residency on two timescales:
Immediate Residency (183-Day Rule)
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.
Full Residency After 270 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.
Ending Norwegian Tax Residency
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 β you must notify the tax authorities and demonstrate you have a permanent home abroad and no longer maintain strong Norwegian ties. For the first 1β3 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.
Section 04
Social Security and Employer Costs
Norwegian social security (trygd) provides extensive benefits including healthcare (free at point of use), parental leave, unemployment insurance, and pension. Contributions are:
Employee trygdeavgift: 7.6% of gross employment income (2026)
Employer arbeidsgiveravgift: varies by region, ranging from 0% (northern zones) to 14.1% (main zones) β most employers in Oslo/Bergen pay 14.1%
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.
Benefits for Expat Employees
Once enrolled in the Norwegian National Insurance Scheme (Folketrygden), expats are entitled to the same benefits as Norwegian citizens, including:
Free healthcare at public hospitals and GPs (GP system β fastlege)
Unemployment benefits (dagpenger) after 12 months of contributing
Pension accrual
Parental leave pay (up to 49 weeks at full salary)
Section 05
Filing and Key Dates
Norway pre-fills most employees' tax returns (skattemelding) using data from employers and banks. The process:
In April, Skatteetaten publishes your pre-filled return online via skatteetaten.no
Review and correct if needed β particularly for foreign income, investment accounts, or moving year deductions
File by April 30
Tax settlement (skatteoppgjΓΈr) is issued in June/July
Any underpayment is due on the settlement date; overpayments are refunded with interest
If you are on the PAYE scheme, you do not need to file an annual return β 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.
Section 06
US Citizens in Norway
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 β but filing is still required.
Form 1040: Required annually for all US citizens regardless of Norwegian residency
Foreign Tax Credit: Norwegian income taxes (roughly 25β40% effective at typical expat salaries, with a 47.4% top marginal rate) exceed US rates at most income levels, so additional US tax is rarely owed on employment income
FEIE: The Foreign Earned Income Exclusion (up to ~$132,900 in 2026) is an alternative to FTC β not combinable with FTC on the same income, but sometimes beneficial at lower income levels
FBAR: Required if Norwegian bank accounts exceed $10,000 at any point during the year
Living in Norway as a US citizen means filing in both countries. Greenback's expat CPAs handle your Form 1040, FBAR, and Foreign Tax Credit optimisation for your Norwegian income β so you're never paying more tax than you have to.
β Not the cheapest option β best for complex situations and expats who want a dedicated CPA.
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 17.8% above 1,467,200 NOK (~β¬130,000) in 2026. Combined with the 22% base tax and 7.6% national insurance, the top marginal rate is 47.4%.
Q
What is the PAYE scheme in Norway and should I use it?
The PAYE scheme lets new foreign workers in Norway pay a flat 25% of gross salary as their entire tax and national insurance obligation β no annual return required. It's available for your first two income years. At lower incomes (below ~670,000 NOK on 2026 rates), the standard system with deductions produces a lower rate. At higher incomes, PAYE's flat 25% is usually cheaper and much simpler. Assess with a Norwegian tax adviser.
Q
When do I become a Norwegian tax resident?
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.
Q
What are Norway's income tax rates at β¬80,000?
At approximately 900,000 NOK (around β¬78,000), the combined marginal rate is: 22% fellesskatt on taxable income (after deductions) + 13.7% trinnskatt on gross income at that bracket + 7.6% trygdeavgift = 43.3%. The effective total tax rate is approximately 29% (about NOK 262,000) with the standard 2026 deductions. Use the Norway Tax Calculator for a personalised estimate.
Q
Is healthcare free for expats in Norway?
Yes. Once enrolled in the Norwegian National Insurance Scheme (Folketrygden) β which happens automatically upon taking up employment and paying trygdeavgift β 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.
Q
Can I use the Foreign Tax Credit to eliminate US taxes on Norwegian income?
In most cases, yes. Norway's effective income tax rate (roughly 25β40% at typical expat salaries) 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.
Q
What is the employer national insurance rate in Norway?
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 β a meaningful consideration for remote workers whose employer is based in those areas.
