Tax credit muddle

[TryingToForgeAnewLife]

Hi. I am getting in a muddle and would appreciate help! I started claiming TC June 2017. As of April 2018 my payments dropped as according to the original award paperwork they seemed to expect a rise in salary. I used my 2017 P60 to give them my original figures but l'm wondering if l have given the wrong figures.

I have two P60 - one from my main job and the other from overtime. I added them together to get the total that l earned. Was that correct?

Also what amount do l put down from the P60? Is it the amount that is stated in "This Employment" box (this is the same figure as the Total for Year also on the P60)?

I have looked on the Gov Gateway and the amounts on there match my P60 "This Employment"/"Total for Year" figures

Many thanks

Sounds right to me. Just read through the notes online and check you aren't able to make any deductions eg charity donations or private pension. They are only interested in taxable pay.

Many thanks for your reply.

I managed to get an online chat with them and they confirmed that l do add together all my P60 from the Total for year and give them that figure.

Now interestingly... my salary in 17/18 has dropped from 16/17 but when l updated my tax credits (and then started thinking I'd used the wrong figures)... my award has decreased too

My 18/19 provisional award is also less as they used an estimate which included a payrise. I won't be getting one (Nhs!) but again when l updated that on line, my recalculated amounts are still less than what l have been getting
