HMRC payment demand: what it means and how to handle it

What this letter usually means

A payment demand is HMRC asking you to pay tax they believe is owed and unpaid. It might relate to Self Assessment, VAT, PAYE, Corporation Tax or another tax. The letter will usually show the amount, the period it relates to, and how to pay. It may also mention interest, which continues to build up until the balance is cleared.

It is worth knowing that a demand is not always based on figures you have confirmed. Sometimes HMRC raise a demand on estimated or out of date figures, for example where a return is outstanding and HMRC have issued their own estimate, known as a determination. That means the amount demanded can be too high, too low, or simply wrong, and it is always worth checking before you pay or panic.

The key message is calm but clear. A demand is a serious letter that should not be ignored, but it is also one you can usually resolve, either by correcting it, paying it, or arranging to pay over time.

Who it affects

Anyone who owes tax can receive a payment demand. That includes the self employed and sole traders, landlords, company directors, and businesses of every size. People who file Self Assessment are a common group, particularly where a payment on account has been missed or a balancing payment has fallen due. Our Self Assessment guide explains how these payments arise.

Demands often follow a missed deadline. If a return was filed late, paid late, or not filed at all, HMRC may issue a demand alongside penalties and interest. You can read more about how charges build up on our HMRC penalties guide, and about the key dates on our UK tax deadlines page.

Cash flow problems are common and nothing to be ashamed of. Many people receive a demand simply because money was tight at the wrong moment. HMRC deal with this situation all the time, which is exactly why arrangements to pay in instalments exist.

What you must not ignore

Ignoring a payment demand is the one route that almost always makes things worse. If a demand is left unanswered, HMRC can escalate. They may pass the debt to a debt collection agency, take control of your goods through a process known as distraint, or take court action to recover the money. In serious cases there are further enforcement powers. Interest continues to run throughout.

None of this happens instantly, and most of it can be avoided by simply engaging. HMRC would generally far rather agree a sensible way for you to pay than escalate. The trigger for escalation is usually silence, not the existence of the debt itself.

So even if you cannot pay, do not put the letter in a drawer. Contact HMRC, or have an accountant contact them for you, well before the payment date. Doing so keeps the situation in your hands and protects you from the more aggressive recovery steps.

What you may need to gather

Before you respond, it helps to have the facts in front of you so you can check whether the demand is right and, if needed, show HMRC you can stick to an arrangement. Useful items include:

• The demand letter itself, and any earlier statements or notices
• Copies of the tax returns for the period in question
• Confirmation of any payments you have already made, with dates
• Your bookkeeping records or accounting software figures
• A simple picture of your income and outgoings, if you may need Time to Pay
• Details of any return that is still outstanding

If the demand is based on an estimate because a return is missing, filing the actual return is often the fastest way to replace the estimate with the correct figure. Keeping your bookkeeping up to date makes all of this far quicker and helps you respond with confidence.

What to do, step by step

A demand feels less overwhelming when you work through it in order.

• Open it and read it carefully. Note the amount, the period, the payment date and how to pay.
• Check it is correct. Compare it with your returns and records. Is it based on actual figures or an estimate?
• If it looks wrong, work out why, for example a missing return or a payment not recorded, and contact HMRC to correct it.
• If it is right and you can pay, pay by the date shown to stop interest building up further.
• If you cannot pay in full, ask HMRC about a Time to Pay arrangement to spread the cost in instalments.
• Do not ignore the payment date. Engage before it passes, even if only to explain your position.
• Keep records of every call, letter and payment.

If any of this feels daunting, an accountant can check the demand, deal with HMRC and negotiate an arrangement on your behalf.

A worked example

Before paying, Daniel checks the figure against his actual records and realises the estimate is much higher than his real profit for the year. He brings his bookkeeping up to date and files the outstanding return. Once the actual figures are in, the correct tax is significantly lower than the demand, because the estimate had assumed earnings he never made.

The corrected amount is still more than Daniel can pay in one go. Rather than ignore it, he contacts HMRC and asks for a Time to Pay arrangement, offering monthly instalments he can realistically afford based on his income and outgoings. HMRC agree. Interest still runs on the outstanding balance, but the debt is now under control, the threat of escalation is removed, and Daniel has a clear path to clearing it. Checking the demand first saved him from overpaying, and engaging early gave him a manageable plan.

When to speak to an accountant

It is worth speaking to an accountant as soon as a demand arrives, particularly if the amount looks wrong, if a return is outstanding, or if you know you cannot pay in full. The earlier you act, the more room there is to correct mistakes and agree a sensible arrangement before any escalation begins.

An accountant can check whether the demand is accurate, file any missing returns to replace estimated figures, deal with HMRC on your behalf, and negotiate a Time to Pay arrangement that fits your real circumstances. If the demand sits alongside penalties or a wider review, they can help with that too. Our compliance check guide covers what to do if HMRC are also looking into your records.
