Are vouchers for surveys completed taxable and to be put on a self-assessment tax return? I often do surveys in return for small voucher amounts, and these build up over the course of a year, eg around £100 in total and are mostly Amazon vouchers.
I sometimes also do surveys for small cash payments and will declare these on my tax return, but am unsure about voucher payments.
I do this alongside my main job (I am self-employed, ie not PAYE, and complete a tax return).
Are these voucher amounts to be put on a tax return?
