The mechanics are that the allowance will be obtained via standard payroll software and HMRC’s RTI system. A facility will be added to the RTI Employer Payment Summary referring to the allowance in the form of a “yes/no” indicator, with payroll software providers doing the same. The employer then offsets the allowance against each monthly Class 1 secondary NICs payment until fully claimed or the tax year ends. For the following tax year the allowance is available against NICs as the liability arises during the year.
For a small company rewarding working shareholders by way of dividends, the current thinking is that from 6 April 2014 it will usually be best to receive remuneration of £10,000 per annum instead of limiting it to the NIC secondary threshold of (currently) £7,696 as is normally done. This is because earnings of £10,000 will fully utilise the new level of personal allowance, whereas dividends effectively waste the allowance. We will do the calculations for you, to reflect your own circumstances.
