An HMRC Time to Pay arrangement is a payment plan that lets you clear a tax bill in monthly instalments instead of in one go. You can often set one up yourself online if you owe Self Assessment tax, or by phone for other taxes, and HMRC will ask about your income, spending and any savings or assets before agreeing an amount. Interest keeps running on the outstanding balance throughout, currently at 7.75% from 9 January 2026, so the sooner you contact HMRC the less it costs overall.
What is HMRC Time to Pay?
Time to Pay is HMRC's name for a payment plan on an overdue tax bill, set out on its If you cannot pay your tax bill on time guidance. Rather than paying the full amount by the due date, you agree to pay it off in monthly instalments. HMRC checks whether the plan is affordable for you based on what you earn and what you spend. If you cannot agree a plan, HMRC will ask you to pay the amount you owe in full.
This is not automatic and it is not a write-off. You still owe the tax, and interest continues to accrue on the unpaid balance until it is cleared.
Can I set up a payment plan myself?
Yes, for many Self Assessment bills you can use HMRC's online payment plan service to check eligibility and set up instalments without speaking to anyone. To use it you need the reference number for the tax you cannot pay (usually your Unique Taxpayer Reference from a letter HMRC has sent you), a UK bank account you are authorised to set up a Direct Debit from, and details of your income and spending.
If your bill is not yet overdue and you simply want to spread the cost of your next Self Assessment bill, a Budget Payment Plan is a separate, different route worth knowing about.
If you cannot set up a plan online, for example because your debt is a different tax or the online tool does not cover your situation, you contact HMRC directly and talk it through.
What does HMRC ask about?
HMRC wants a realistic picture of what you can afford, not just what you would like to pay. The table below sets out what it asks for and why.
As a broad guide, HMRC's own guidance says you will usually be asked to pay around half of what is left over each month after your fixed outgoings, though this depends entirely on your figures. You can offer to pay more than that if you want to clear the debt faster and pay less interest overall.
What if I have used independent debt advice already?
If you have already been through independent debt advice, for example from Citizens Advice, and have a Standard Financial Statement, HMRC will accept this as evidence of your income and outgoings rather than asking you to go through the exercise again.
How long does a payment plan last, and what if my circumstances change?
There is no fixed time limit on a Time to Pay arrangement. How long it runs for depends on how much you owe and what you can realistically afford each month. If anything changes, for better or worse, you should contact HMRC: a plan can be made longer or shorter, and if HMRC becomes aware your circumstances have improved it may get in touch to discuss revising your repayments.
If you miss a payment, HMRC will contact you to find out why and, where possible, will try to rearrange the plan with you rather than cancel it outright. If you cannot pay a further tax bill while a plan is running, contact HMRC: it may be possible to fold the new bill into the existing arrangement.
What happens if I do not contact HMRC at all?
HMRC will always try to make contact if you miss a tax payment, including by letter, text, and sometimes a visit to your home or workplace. If you do not respond, or you cannot agree a plan, HMRC's enforcement options include instructing a debt collection agency, taking payments directly from your wages or pension, taking or selling belongings you own, taking money directly from a bank or building society account, court action, bankruptcy proceedings, or, for a business tax debt, action to close down the company. Any costs involved, such as auction fees, are normally added to what you owe. HMRC says it will explain your rights, costs and options before taking any of these steps.
Worked example
Example. Consider a self-employed decorator who owes £4,800 in Self Assessment tax after a slower year for work, with the balancing payment due on 31 January. He knows he cannot pay it in full by the deadline. In week one he logs into his HMRC online account and checks whether he is eligible to set up a plan through the online service, using his Unique Taxpayer Reference from his statement of account.
The online tool asks for his monthly income and his fixed outgoings, rent, van costs, utilities, so it can work out what is realistically left over. He has no significant savings to draw on first. Based on his figures, he is offered a plan spread over several months by Direct Debit. He knows interest will keep accruing on the outstanding balance at HMRC's current rate until it is cleared, so he chooses to pay slightly more than the minimum offered each month to bring the total interest down. He also flags that he has a VAT bill due later in the year, so that if he cannot pay it in full he knows to contact HMRC promptly rather than let it become a separate, unmanaged debt.
What to do in week one
Do not wait until the deadline has passed to think about this. If you already know you cannot pay, start now
Working out the numbers and making first contact is something most people can do themselves. Where it helps to have an adviser is when the debt spans more than one tax, when a company is involved and directors are being asked to put in personal funds, or when the amount HMRC is asking for does not match your own understanding of what you owe. If the wider issue is one of ongoing tax planning rather than a single overdue bill, that is worth a separate conversation once the immediate payment position is settled. If HMRC has also opened a formal check alongside the payment issue, our tax investigations page covers how that process works.
