If your 2009/10 self assessment tax return has already been submitted (well done!), you should have received a self assessment statement this week. This statement includes a payslip and instructions on the back with all the possible methods of payment.
If you have only recently submitted your return (or, like many others, still in the last minute panic of trying to submit before the 31 January deadline!), you can pay your bill online here:
Get in touch if you need any more information on how to pay the bill. Make sure you do it before 31 January. If you are unable to make the payment before 31 January, call HMRC's business payment support service (0845 302 1435) to see if they are able to assist you in arranging a payment plan.
