I have just taken on a sole trader who pays his wife for (genuinely) helping in the business. The total amount is above the LEL but below the PAYE threshold. The workload varies during the year and during several months she does a lot more work than at other times, though she does something every month.
Is it OK to pay her an averaged monthly wage rather than for the actual hours worked? She will have to pay NICs during some months if the latter.
I know in some jobs such as teaching the pay is averaged over the year despite school holidays etc.
Thanks for any advice.
