National insurance contributions
National Insurance contributions are paid on earnings from employment and self-employment, including profits above the relevant thresholds, and they help build entitlement to certain state benefits and the State Pension.
National Insurance is not payable on income such as savings interest, dividends, rental income, or pension income, and no contributions are due where earnings fall below the minimum thresholds.
Different classes of National Insurance apply depending on whether income arises from employment or self-employment, and contribution requirements depend on the level of earnings or profits.
