Hope you can help!
We have a director who is an employee, so we have ignored the fact that he is a director for this tax year so far.
My problem is that he received a bonus this month (this will be the only month he receives extra) and last year when we used HMRC's software, it resulted in him having an underpayment when it came to month 12, so am trying to make sure we don't have the same problem this year. I have just calculated month 5 to see what the figures are, and ignoring him as a director just goes back to what he was paying in months 1-3, and flagging him up as a director means he is paying even less from month 5 onwards! Having worked out what his total gross pay will be for the year, I used HMRC's "Director's Annual Earnings Period Check" and based on what he is paying, it will leave him with an underpayment at the end of the year of £280.27! Am I missing something? Can I do the check that HMRC software does to work out NIC on a cumulative basis, as I can't see how to do this? I tried checking the APP box but this did not seem to have any effect when recalculating.
For 11 months this director/employee earns £2539 and for one month only he earns £6462 = £34391. According to HMRC, he should be paying £3153.36 NIC for the year.
Hope this makes at least a little sense
