HMRC charges an automatic £100 penalty for a late Self Assessment return, even if you owe no tax at all. The online filing deadline is 31 January, and it does not move. Beyond three months late, HMRC adds £10 a day, up to £900 more. This is why your return needs to be prepared with enough time to check it, not rushed together in the final week of January.
We handle registration, expense and relief claims, and the return itself for sole traders, landlords, and company directors across Slough. Clients with clean bookkeeping throughout the year get a faster, more accurate return, since the figures are already reconciled before we start. If you rent out property, we also coordinate this with your landlord accounting to keep rental income reporting consistent.
The £100 penalty applies the moment the clock passes midnight on 31 January, whether or not you owe HMRC a penny. Many people assume a penalty only applies if tax is unpaid, and are caught out by a return that was simply late. This is exactly why the return itself matters as much as the payment. We build in a review stage before every submission, so nothing is filed at the last minute.
This service is built for anyone in Slough who needs to report income HMRC does not already tax at source.
We register you for Self Assessment and obtain your Unique Taxpayer Reference if you do not already have one.
We check every allowable expense and relief against your records, so you are not overpaying.
Your return is prepared, checked, and filed online well ahead of the 31 January deadline.
Any HMRC query relating to your return is handled directly by us.
The online filing deadline is 31 January, following the end of the tax year on 5 April. Paper returns are due earlier, on 31 October.
