These days, both personal tax returns and corporation tax returns are generated by us using software which has been approved by HMRC. The process includes the creation of a unique IR Mark which is established by applying a formula to the data in the return. This means that every tax return has a totally unique IR Mark.
We ask clients to check tax returns carefully to ensure that all income has been declared and that all allowances have been claimed. When you are satisfied that the return is correct and complete, HM Revenue & Customs will accept authorisation electronically.
We are permitted to file electronic tax returns only when we are satisfied that the IR Mark on our digital file is the same as the one on the document that you have approved. If any amendment is required to a tax return, then a fresh document needs to be prepared and sent out again for approval. That’s because the IR Mark changes after even the most elementary revision.
The Self Assessment tax return deadline normally falls ten months after the tax year ended, and you need to ensure it is submitted by 31 Jan. Please remember that in law, the responsibility for filing a tax return on time and for paying tax lies with you the taxpayer.
There are automatic penalties for late tax returns, so we encourage clients to approve them as soon as possible. Once submitted, we can provide details of the electronic proof of receipt.
