Missed the 31 January deadline, or behind on several years? It is fixable, and the sooner it is dealt with the less it costs. We file your outstanding returns, deal with HMRC, appeal penalties where there is a reasonable excuse, and arrange Time to Pay if you cannot clear the bill at once.
Late Self-Assessment, UK
HMRC charges an automatic £100 penalty the moment a Self Assessment return is late, even if you owe no tax. After three months it adds £10 a day, up to £900. At six months and again at twelve months it adds a further 5% of the tax due or £300, whichever is greater. On top of that, late payment of the tax itself attracts interest and its own 5% surcharges at thirty days, six months and twelve months. The penalties stack quickly, which is exactly why the worst thing to do is nothing.
Your Tax Help Accountants brings late filers back on track every week. Whether you have missed one deadline or have several years of arrears, a missing UTR or a stack of HMRC letters, we take it over. We register or re-register you, file every outstanding return in the right order, agree a Time to Pay arrangement with HMRC if the tax cannot be paid immediately, and submit penalty appeals where there is a reasonable excuse. Most cases are fully back on track within four to six weeks, and the stress lifts the moment someone else is handling it.
The penalties only grow with time, but they stop the moment your returns are filed. The single most expensive thing you can do is keep putting it off, the cheapest is to deal with it now.
What We Handle
One missed year or several, we file every outstanding return in the correct order and bring your whole position up to date.
We deal directly with HMRC, respond to penalty notices and correspond on your behalf as your authorised agent, so the letters stop landing on you.
Where there is a reasonable excuse, illness, bereavement, HMRC error and more, we appeal the penalties and frequently get them reduced or cancelled.
If you cannot clear the tax at once, we negotiate a Time to Pay instalment arrangement with HMRC so it is spread over manageable months.
Never registered, or lost your UTR? We register or re-register you for Self Assessment and get your UTR so filing can begin.
While bringing you up to date we claim the expenses and reliefs that were missed, which often reduces the bill the penalties were calculated on.
Multi-year arrears feel overwhelming, which is exactly why people leave them, and the penalties grow while they do. It is far more routine to fix than it feels. We have brought clients back from five and six years of missed returns. We sort the filings, deal with the penalties, and arrange a payment plan if needed, so it becomes a closed chapter rather than a constant worry.
Recent Client Outcome
A self-employed courier came to us with three years of unfiled returns and a drawer of HMRC penalty letters he had stopped opening. He assumed the bill would be enormous and had frozen, which only made it worse as the daily and six-month penalties accrued.
We registered as his agent, requested his UTR details, and filed all three years in order, claiming the mileage and costs he had never recorded, which brought the actual tax down significantly. We then appealed the penalties on the years where there were grounds and negotiated a Time to Pay arrangement for the balance.
The claimed expenses and the successful appeals roughly halved what he owed in penalties and tax combined, and the Time to Pay plan spread the rest over manageable monthly instalments. He is now filed on time each year and no longer dreads the post.
