Emergency Tax

How does one claim back emergency tax and can it be done online with ros

If you have had your cert of tax credits sent to your employer they should refund you any overpaid amount through your pay. If you have not done this yet you should contact your tax office asap. Also make sure you are claiming all the tax credits you are entitled to.

If you do not receive a refund through your pay then you can register for paye self service and make a claim after the tax year end (31st December).
