Tax Rebate

[malagabob]

My accountant told me after calculating 2013/14 tax return, how much he can get me in rebate. He did not ask at the time ,and I did not mention it that I am in receipt of pension.
As I am of retirement age but worked beyond 65 my pension is liable for tax as it took me over how much I can earn. He has now been informed I am in receipt of state pension.
My accountant now says I am due a lot less.
Can he get me the initial amount back, and leave it up to me to pay any tax owed by Jan 31st 2015, or does he need to submit the amended return. TIA

I am not certain but I'd have thought it's best to submit the amended return, otherwise HMRC may suspect you are trying to evade tax.

Yes, factor is quite right. You have a duty to accurately declare your circumstances to HMRC. If you (or your accountant) has made an error tell them immediately.
