Hi! James here.
Your tax return? Consider it done.

What is a Self Assessment

Self Assessment is a system HM Revenue and Customs (HMRC) uses to collect Income Tax.

If you have income that isn’t taxed through a pay-as-you-earn (PAYE) scheme, you’ll probably need to submit a personal tax return. If you’re self employed or a sole trader and your turnover was more than £1,000 or you’re in a business partnership, you must complete a return.

Filing is as easy as 1,2,3
