For many taxpayers, settling a tax bill in one lump sum can feel daunting, particularly during periods of financial pressure. HMRC recognises that circumstances vary and offers several structured paths to spread payments across manageable instalments. These routes differ depending on the type of tax involved, the size of the liability, and whether the taxpayer is an individual, a self-employed person or a company. While interest will usually apply, the supported payment methods can prevent penalties and reduce financial stress.
This guide outlines the recognised options available when you find yourself unable to pay your tax bill on time. It explains how each approach works, what HMRC expects, and how to stay within the rules.
Understanding HMRC’s Time to Pay Arrangements
A Time to Pay (TTP) arrangement is the most widely used method of spreading overdue tax. According to HMRC’s 2024/25 Annual Report, more than 913,000 individuals were using a TTP arrangement, covering around £6.16 billion of tax debt. These figures underline how common it is for taxpayers to need extra time to settle what they owe.
A TTP plan is not something that HMRC must grant automatically; it is a negotiated agreement. In most cases, the arrangement lasts for around 12 months. Longer plans are possible, although these only arise in exceptional situations and require managerial approval within HMRC.
Eligibility for Self-Employed Taxpayers
Those who are self-employed can apply online provided that:
- The latest self assessment return has been filed
- The total outstanding debt is below £30,000
- No other HMRC debts or existing payment plans are in place
- The application is submitted within 60 days of the payment deadline
If these conditions are met, the online system allows you to spread payments over a default 12-month period. Where the situation falls outside these criteria, the individual must contact HMRC by phone, after which a formal written agreement may follow. Applicants must also disclose their income and expenditure, as HMRC uses this information to assess how much you can realistically pay.
When a Time to Pay Arrangement Might Be Refused
HMRC may decline or cancel a TTP arrangement if a taxpayer has a record of submitting returns late, has ignored previous correspondence, or has failed to update HMRC about changes in their financial situation. If a proposal is rejected, the taxpayer may face additional interest charges or penalties, and HMRC may begin enforcement action to secure the debt.
Using Time to Pay for Other Forms of Tax
TTP arrangements are not limited to self assessment. They can apply to arrears of VAT, PAYE, Class 4 National Insurance and corporation tax. The conditions, however, are more stringent. Businesses often need to demonstrate that they are viable and supply evidence such as bank statements and cashflow forecasts. The aim is to show HMRC that although the business cannot pay the full amount immediately, it remains a going concern.
PAYE Coding Adjustments for Employees
Employees and pension recipients with an underpayment of £3,000 or less will usually see HMRC collect the shortfall through their tax code for the following year. This reduces the person’s tax-free allowance and spreads the liability across 12 months. This method is interest-free and happens automatically unless the taxpayer indicates on their return that they prefer not to settle the debt through their code.
This approach is simple and avoids the need for a separate instalment plan. It also enables employed individuals to spread the cost without setting up a direct debit or dealing with HMRC directly.
Short-Term Deferrals
In rare situations, HMRC may permit a very short extension without a formal arrangement. This only happens where the difficulty is temporary and beyond the taxpayer’s control, such as suddenly being admitted to hospital. Even in these cases, HMRC must be contacted as soon as possible.
Budget Payment Plans for Future Bills
A Budget Payment Plan (BPP) is a voluntary option that helps taxpayers build funds towards their next self assessment liability. Payments can be weekly or monthly and must be made by direct debit. Unlike a TTP arrangement, the BPP applies only to future liabilities and can only be set up when the taxpayer’s HMRC account is fully up to date.
Although BPPs offer peace of mind, they do not carry interest, meaning you might receive a stronger return by saving in a deposit account instead. The value of a BPP lies in its predictability, not in financial gain.
Avoiding Late Payment Penalties
Interest begins to accrue from the moment tax becomes overdue, but penalties only arise on specific trigger dates. If a self assessment bill remains unpaid 30 days after the deadline, HMRC applies a 5% late payment penalty. The same charge can follow again at six months and twelve months after the deadline.
For a tax bill due on 31 January 2026, the first 5% penalty would fall on 2 March 2026. However, this penalty can be avoided if a Time to Pay arrangement is in place by that date and the taxpayer keeps up with the agreed instalments. Interest will continue to apply, but penalties will not.
This demonstrates how critical it is to approach HMRC early. The sooner you act, the more options will be available and the fewer extra charges will arise.
When to Seek Advice
Anyone struggling to pay a tax bill should act well before the due date where possible. Leaving matters until reminders or enforcement notices begin to arrive limits the flexibility HMRC can offer. A professional adviser can help you prepare the information HMRC expects, assess which payment method best suits your situation, and ensure that any application reflects your circumstances clearly and accurately.
