Norway Income Tax 2026 — Complete Guide
Norway combines a flat 22% base income tax with a progressive surtax (trinnskatt) and 7.9% social security. The base tax applies after a personal deduction (NOK 79,600) and minimum deduction (minstefradrag). Trinnskatt applies to total gross personal income without these deductions, creating a hybrid progressive system.
2026 Trinnskatt Steps
Step 1: 1.7% on NOK 208,050 – 299,700
Step 2: 4.0% on NOK 299,700 – 670,000
Step 3: 13.6% on NOK 670,000 – 937,900
Step 4: 16.6% on NOK 937,900 – 1,350,000
Step 5: 17.6% on income above NOK 1,350,000
Personal allowance (personfradrag): NOK 88,250
Base tax: 22% × max(0, income − minstefradrag − NOK 88,250)
Minstefradrag: 46% of income, max NOK 109,950
Social security: 7.9% of gross income
Step 2: 4.0% on NOK 299,700 – 670,000
Step 3: 13.6% on NOK 670,000 – 937,900
Step 4: 16.6% on NOK 937,900 – 1,350,000
Step 5: 17.6% on income above NOK 1,350,000
Personal allowance (personfradrag): NOK 88,250
Base tax: 22% × max(0, income − minstefradrag − NOK 88,250)
Minstefradrag: 46% of income, max NOK 109,950
Social security: 7.9% of gross income
Example — NOK 650,000, Class 1
Minstefradrag: min(650,000×46%, 109,950) = NOK 109,950
Base tax: (650,000 − 109,950 − 79,600) × 22% = 460,450 × 22% = NOK 101,299
Trinnskatt Step 1: (292,850−208,051) × 1.7% = NOK 1,442
Trinnskatt Step 2: (650,000−292,850) × 4.0% = NOK 14,286
Social security: 650,000 × 7.9% = NOK 51,350
Total: ~NOK 168,377 | Effective: 25.9% | Take-home: NOK 481,623
Base tax: (650,000 − 109,950 − 79,600) × 22% = 460,450 × 22% = NOK 101,299
Trinnskatt Step 1: (292,850−208,051) × 1.7% = NOK 1,442

Frequently Asked Questions
How does Norway's trinnskatt (bracket tax) work in 2026?
Trinnskatt is a surtax added on top of Norway's 22% flat base tax. For 2026 it has 5 steps: 1.7% on income NOK 208,050–299,700; 4.0% on NOK 299,700–670,000; 13.6% on NOK 670,000–937,900; 16.6% on NOK 937,900–1,350,000; and 17.6% on income above NOK 1,350,000. Each step is progressive — you only pay the higher step on the income within that range, not on all income.
What is Norway's personal allowance (personfradrag) for 2026?
The personfradrag (personal deduction) is NOK 88,250 for 2026. This amount is deducted from gross income before calculating the 22% flat base tax. However, trinnskatt applies to total personal income before this deduction — so you may pay trinnskatt even if your income is near the threshold. The personal allowance effectively makes the first ~NOK 88,250 free from the base income tax.
What social security (trygdeavgift) does an employee pay in Norway?
Norwegian employees pay 7.9% in trygdeavgift (social security contribution) on their gross salary in 2026. This is collected by the employer via payroll (skattemelding). There is a minimum income threshold below which the rate drops to 0 and a reduced rate of 5.1% applies on certain pension income. Employers additionally pay arbeidsgiveravgift (~14.1% in most of mainland Norway, varies by region).
How is Norway's flat 22% base tax calculated?
The 22% base tax (alminnelig inntekt) applies to the same income after subtracting the personal deduction (NOK 79,600) and standard deductions such as minstefradrag (minimum deduction, max NOK 109,950 for employment income at 46%). So the base tax is: 22% × max(0, income − min(income × 46%, 109,950) − 79,600). This differs from trinnskatt which applies to total gross personal income without the minimum deduction.
What is the top effective tax rate in Norway for 2026?
For very high earners (above NOK 1,350,000), the marginal rate stacks to: 22% base tax + 17.6% trinnskatt + 7.9% social security = 47.5% marginal rate. However, in practice the effective rate is lower because the base tax uses deductions (personfradrag NOK 88,250 + minstefradrag) and trinnskatt applies progressively. There is also a separate 0.95% wealth tax on net wealth above NOK 1.7 million, which further increases the effective burden for asset-holders.
