Norway

Norway uses a dual income tax system separating ordinary income (alminnelig inntekt) and personal income (personinntekt). Ordinary income is taxed at a flat 22%. On top of this, a progressive surtax (trinnskatt) applies in four steps: 1.7% on income above NOK 208,050, 4.0% above NOK 292,850, 13.6% above NOK 670,000, and 16.6% above NOK 937,900. Social security contributions for employees (trygdeavgift) are 7.9% of gross income. Employer contributions (arbeidsgiveravgift) are 14.1% in most areas, with reduced rates in designated zones to encourage economic development in northern and rural Norway. Norway's petroleum wealth funds a generous welfare state. The Government Pension Fund Global (the world's largest sovereign wealth fund, exceeding $1.5 trillion) provides fiscal stability. Personal tax deductions include a standard deduction for employment income, commuting costs, and union dues. Capital gains are taxed at 22%, with an uplift factor of 1.72 applied to dividends and capital gains from shares (effective rate approximately 37.8%). VAT is 25% with reduced rates of 15% (food) and 12% (transport, cultural). The corporate tax rate is 22%. Norway has tax treaties with over 80 countries.
