Self Employed Tax Calculator 2020-2021

Self employment profits are subject to the same income taxes as those taken from employed people. The key difference is in two areas, National Insurance Contributions and the ability to deduct expenses and costs before calculating any deductions.

Self employed people pay a lower rate of NIC (National Insurance) contributions called Class 4 national insurance. They also pay a weekly fixed rate Class 2 NIC.

Class 2 NICs can be avoided if self employment profits are below the exemptions limit.
