Hi. I have sent off my tax return for 14/15 but I think I may have to amend it. Last December I did a one off job for another company and they paid me via their payroll. It was for £700 but I was paid £560 as they deducted the tax, NI etc. So my question is, how do I enter this on my tax return? I included the £560 in my figures but I didn't do it as a separate income. I'm a bit confused as I have already paid the tax on it.
Any advice welcome, thanks.
