Thanks for the responses. Peter please see below; I have copied and pasted from hmrc website;
'Making changes 12 months after the deadline
Write to HMRC to tell them about a change to your tax return if the deadline was more than 12 months ago.
Include in your letter:
the tax year you’re correcting
why you think you’ve paid too much or little tax
how much you think you’ve over or underpaid
You can claim a refund up to 4 years after the end of the tax year it relates to. If you’re making a claim, also include in your letter:
that you’re making a claim for ‘overpayment relief’
proof that you’d paid tax through Self Assessment for the relevant period
how you want to be repaid
a signed declaration saying that the details you’ve given are correct and complete to the best of your knowledge'
Since posting the question on Here, I have spoken with HMRC again, I explained to the advisor on the phone the situation and how advice previously given contradicts what I see on the website, I was told to FOLLOW THE WEBSITE!. I asked if I sent a amended return signed and dated by the client will this be accepted and I was told no as they need a letter from the client. I intended to send the return with a covering letter from us, but don't want to waste my time if this will only be rejected. Can't get the client to sign a letter as he is abroad till February.
