Eg: Your total Payer Class 1 National Insurance liability for the year is £ 2000.00 the Employment allowance lowers your Payer Class 1 National Insurance each time you run payroll in contrast to your total liability.

You can claim Employment Allowance at any time during the tax year.

If you are continuing a claim from the tax year to the tax year , you must send an EPS in month 1.

If you make a late claim and have a large unused Allowance, you will need to ask HMRC to do one of the following: offset the unused balance against other current or future PAYE liabilities so, wherever possible, the unused balance of the Allowance does not go waste, or give you a refund of any unused balance of the Allowance provided you do not have any other liabilities.
