Child Tax Credit question?

Question

If my salary changes do I need to send proof of the new amount and also do I need to send a copy of my P60 at the end of the tax year, ty

Answer 1

Technically you only have to report changes in income of 25,000 p.a.

That said I always think it best to write informing HMRC of new details.

Answer 2

no you don't need to send copies.

you don't need proof either.

at the end of the year you look at the p60 so u can put the right amount on the form but they don't need to see it
