The following are some Calculators which provide indicative Tax & National Insurance liabilities. The figures provided are indicative only and no guarantee is given to their accuracy, or liability accepted for any decisions made resulting from their use. If in doubt please seek guidance from a suitably qualified Tax expert.
For taxpayers who are both employed and self employed there is an annual maximum for Class 4 National insurance contributions, to ensure that the taxpayer is not penalised for paying National Insurance under both the Class 1 and Class2/4 systems. The calculation is fairly lengthy to complete by hand. This calculator will output the Maximum Class 4 NI due and indicate whether there is likely to be a refund due. You need only select the relevant financial year, then input the total Class 1 and Class 2 NI paid in the year in question, along with the total assessable profits.
