Question for mranchovy here relating to your question above redrosa..
Is it possible for income earned in her au pair position to be taken into account as 'other income' in her tax code that is given to her in the other job. This assumes the OP doesn't register as an employer at all (if the APs earnings are below the LEL), and the AP contacts the tax office to request her Au Pair earnings are dealt with in this way..?? If it is possible then it may be the easiest solution for the OP.
If not... then my interpretation (based on three au pairs we've had with other jobs though we've dealt with them in a couple of ways, and from mranchovy's comments above) is that (a) you can register as an employer and put in null declarations for her, or (b) if she definitely has no job when you take her on, then don?t register and let her sort it all out at the end of the tax year through her own self assessment.
Option (a) may give your au pair more opportunity to have more net pay in her hand throughout the year. Option (b) assumes you do not need to keep abreast of someone who works for you has taken an extra job (which I always thought was true but the HMRC website is a little misleading as posted above).
If you decide to operate PAYE then your au pair will receive a tax code against each job separately.
Operating PAYE means: -
- It ensures (as long as you get in there first) you don't need to become the 2nd employer so avoid having to transfer PAYE payments to HMRC (though you?ll still need to declare null payments I think).
- It gives your au pair the chance to contact HMRC and ask for her tax codes to be altered to allow any portion of unused allowance she has with you to be applied to the 2nd job. She could also ask for the tax allowance to be shared across each job i.e. if she was only earning a minimal amount in her extra job.
As the PAYE you need to pay is none or very little, you only you only need to submit the declarations quarterly and you can actually now put in a null payslip online to indicate you have no PAYE or NICs due to pay.
If you do get in first and are her main employer then you will initially have all of the tax allowance in the corresponding tax code 647L.
Any 2nd job will have the BR tax code (assuming basic rate of tax is being paid) and all of her earnings in that 2nd job will be taxed at the basic rate. Your au pair can then sort out her tax situation across both jobs in order not to pay too much tax (at least until self assessment would gibe her a refund anyway).
Let's say your au pair arrives and you are paying her below the lower earnings threshold (currently £97). You choose not to register as an employer because you don't need to. There is no tax or NI contributions to be made and there is no need to register her earnings using the P11 forms etc.
Later your au pair gets a 2nd job (this is assuming she is not from Romania or Bulgaria as she wouldn't be legally allowed to work as an employee for some other business). In completing the P46 declaration, your au pair ticks that she has another job.
This 2nd employer then uses the BR code and taxes her at the basic rate against all of her earnings from that employment (BR assumes all of her personal allowance is fully utilised by her 1st job). This would means she should contact the tax office and ask for her unused allowance of £125 - £70 = £55 to be transferred over into the tax code for her 2nd job.
If she waits until year end to submit her self assessment tax form and get a rebate, she will probably need to provide evidence that in her job with you, you really did only pay her £70 a week.
