Parallel permie role for a short period - tax computations

[Craig@Clarity]

Put aside another 20% tax due to HMRC by 31 Jan 12. I don't think there is any need to increase your POA for July 11.

Craig,

Thanks very much for your reply. Yes, for the parallel short permanent employment tax was deducted at BR @20%.

I am a higher rate tax payer. Should I compute the taxes now -without waiting for the personal tax return- considering both employments and request for increase in the Second instalment due in July 2011?

You will effectively have 2 employment so either your Limited company will have a BR tax code or your short parallel employment will. It's probably likely that the perm job will have a BR (Basic Rate) tax code as it would be deemed to be second employment and your salary taxed at 20% income tax for that 1 month stint. If you have underpaid income tax, it will be sorted out on your personal tax return. You will probably not receive a P60 from the perm job as the P45 will have all the details on it already when you leave.

Alongside contracting, if we take short permanent employment and discontinue, how do we merge the PAYE/NI computations.

Eg.,

6 April 2010 - 5 April 2011 - Director in Limited company
1 Jan 2011 - 31 Jan 2011 - Parallel permanent employment ended and P45 issued.

Should the limited company's P60 issued for the period ending 5th April 2011 take into account the salary/taxes paid in permanent employment?
