What sort of NI do I pay?

NI is payable only on earned income not on rents, dividends or other investment income.

As an employee you pay class 1 NI as a percentage of earnings.

As a self employed person you pay class 2 NI which is a flat weekly rate regardless of the level of earnings. You also pay class 4 NI which is a percentage of earnings and is part of the tax we calculate for you.
