Need help with tax

[Mummyto2boys0512]

The last 3 months my partner has been over taxed. Long story with job situation. They taxed him a extra £1000 this month and a extra £800 last month. He rung inland revenue and they've said he can claim in the next tax year. So how do we do it, has anyone done it online before? Or rung? Or so we just wait for a cheque. They've told him he'll get the money back but we need it ASAP.

He can submit a tax return for 2014-15 as soon as the tax year ends next week. They should process it quickly and you get a cheque or bank transfer a few days after confirmation.

How do I do that? Online? I've looked into it online need to register with post office or experience to identify you. Any know why?

Experian that should say

Register for self assessment on line. You need the tax details, ni number etc. although if it is the employer's mistake, they should be able to pay him back.

Can I do this even if he isn't self employed? Will I have to wait until the new tax year before I claim for the last 2 months?

Self Assessment is different to registering as self employed. If there is doubt as to the accuracy of PAYE deductions he should speak to HMRC and determine whether Self Assessment is the best route to recouping it. DH had to do an annual return anyway but got a refund within a month last year for an overpayment. Once he registers for SA he would be expected to submit one until HMRC determine otherwise.
