HMRC Time to Pay: Can You Spread Your Self Assessment Tax Bill?

Receiving a large Self Assessment Tax Bill can be worrying, particularly if you are struggling with cash flow or have not set aside enough money to meet your tax obligations. Whether you are self-employed, a landlord, a company director or someone earning additional income, an unexpected tax payment can create significant financial pressure.

Fortunately, HM Revenue and Customs (HMRC) offers a solution for eligible taxpayers who cannot pay their tax liabilities in full.

Through an HMRC Time to Pay arrangement, you may be able to spread your outstanding Self Assessment Tax Bill over affordable monthly instalments rather than paying everything immediately.

However, these arrangements are not automatically approved. HMRC will assess your financial circumstances, and interest may continue accumulating while you repay the outstanding balance.

In this comprehensive guide, we explain how HMRC Time to Pay works, who qualifies, how to apply, what happens if you miss payments and how to avoid unnecessary penalties.

What Is HMRC Time to Pay?

HMRC Time to Pay is a payment arrangement designed to support taxpayers experiencing financial difficulties.

Rather than requiring an immediate lump-sum payment, HMRC may allow you to repay your outstanding tax liability through regular monthly instalments.

For example, if your Self Assessment Tax Bill is £6,000, you might propose paying £500 per month over 12 months, plus applicable interest.

The arrangement does not reduce or cancel your tax liability. Instead, it provides additional time to settle what you owe.

According to the official HMRC Time to Pay guidance, payment arrangements are considered based on whether taxpayers can realistically afford the proposed repayments.

HMRC generally expects individuals to repay outstanding liabilities as quickly as reasonably possible.

Consequently, Time to Pay should be regarded as temporary financial assistance rather than an interest-free borrowing facility.

The earlier you discuss payment difficulties with HMRC, the greater your opportunity to agree a manageable solution before additional penalties or collection action arise.

When Is Your Self Assessment Tax Bill Due?

Understanding your tax payment deadlines is essential when considering whether you need a repayment arrangement.

For most individuals completing Self Assessment, there are two principal payment dates.

31 January: The deadline for paying any outstanding balancing payment for the previous tax year and the first payment on account towards the current tax year.

31 July: The deadline for making the second payment on account towards the relevant tax year.

For example, the balancing payment for the 2025/26 tax year is normally due by 31 January 2027.

Some individuals face unexpectedly high January bills because they must pay both their previous year’s outstanding liability and an advance payment towards the following tax year.

Suppose your first Self Assessment Tax Bill is £5,000, and you are required to make payments on account.

Your January payment could total £7,500, consisting of your £5,000 liability and an additional £2,500 advance payment.

For further information, review the official Self Assessment payment deadlines.

Understanding these obligations early can help you manage cash flow and avoid financial surprises.

Who Qualifies for HMRC Time to Pay?

HMRC considers payment arrangements for individuals who genuinely cannot settle their outstanding tax liabilities immediately.

However, approval depends on your circumstances and your ability to maintain an affordable repayment schedule.

You may qualify if:

• You are unable to pay your outstanding tax liability in full.
• You can demonstrate genuine financial difficulties.
• You have sufficient income to maintain regular instalments.
• Your proposed repayment schedule is affordable.
• You provide accurate information about your finances.
• You cooperate with HMRC and maintain agreed payments.

Self-employed individuals, landlords, freelancers and taxpayers with irregular earnings may find these arrangements particularly useful.

For example, a landlord facing unexpected property repairs might temporarily lack sufficient funds to pay their tax liability.

Similarly, a sole trader experiencing delayed customer payments may require additional time to settle their Self Assessment Tax Bill.

HMRC considers the circumstances of each applicant individually.

You can review the requirements for setting up an HMRC payment plan before applying.

Can You Set Up an HMRC Payment Plan Online?

Eligible taxpayers can apply for a payment arrangement through HMRC’s online service without necessarily speaking directly to an adviser.

The online facility is designed to simplify applications for taxpayers who meet the relevant eligibility conditions.

Under HMRC’s established Self Assessment online arrangements, qualifying debts have generally been limited to £30,000, with repayment usually expected within 12 months.

Other conditions, including the age of the debt, outstanding returns and existing HMRC payment arrangements, can also affect eligibility.

However, these conditions may change, so taxpayers should check the requirements displayed by HMRC when applying.

If you cannot use the online service, this does not necessarily mean your application will be rejected.

You may still be able to discuss an individually assessed repayment arrangement directly with HMRC.

To check your eligibility, visit the official HMRC online payment plan service.

How Long Can You Spread Your Self Assessment Tax Bill?

The repayment period depends on your outstanding balance, financial position and HMRC’s assessment of affordability.

Although online arrangements are generally aimed at shorter repayment periods, individually negotiated agreements can sometimes last longer.

HMRC confirms that there is no universal maximum duration for a payment plan.

The length depends on what you owe and what you can realistically afford.

Consider the following illustrative examples:

Outstanding Tax	Repayment Period	Monthly Payment
£3,000	6 months	£500
£6,000	12 months	£500
£9,600	12 months	£800
£12,000	18 months	£666.67
£24,000	24 months	£1,000

These examples exclude interest, are for illustration only and do not represent guaranteed repayment periods.

HMRC generally expects taxpayers to clear debts as quickly as they reasonably can.

Longer arrangements may require additional financial information and stronger evidence explaining why a shorter repayment schedule would be unaffordable.

How Does HMRC Assess What You Can Afford?

Before approving a Time to Pay arrangement, HMRC may review your income, household expenditure, savings and outstanding financial commitments.

The purpose is to determine how much you can realistically contribute towards the tax debt each month.

HMRC may consider your:

• Employment or self-employment income.
• Rental profits and other taxable earnings.
• Mortgage or rent payments.
• Household bills and essential living costs.
• Existing loan repayments.
• Savings and available investments.
• Business expenses and financial commitments.
• Expected future changes in income.

According to HMRC’s affordability guidance, taxpayers will usually be asked to pay approximately half of their remaining monthly disposable income towards outstanding tax.

For example, if your household income exceeds essential expenditure by £800 monthly, HMRC might consider repayments of approximately £400.

However, the final amount depends on your individual circumstances.

HMRC may also expect you to use available savings or assets to reduce your debt.

Preparing an accurate income and expenditure assessment before applying can significantly improve the quality of your proposal.

How to Apply for HMRC Time to Pay

Applying for a payment arrangement involves several straightforward steps.

Step 1: Submit Your Tax Return

Ensure your relevant Self Assessment return has been completed and submitted.

HMRC needs to establish the outstanding liability before considering an appropriate repayment arrangement.

You can find instructions on submitting your Self Assessment tax return.

Step 2: Check Your Outstanding Balance

Access your HMRC online account and review your Self Assessment statement.

Check whether the amount includes balancing payments, payments on account, previous debts, interest or penalties.

The official Self Assessment statement guidance explains how your outstanding balance is presented.

Step 3: Calculate Affordable Instalments

Review your income, essential expenditure and financial commitments.

Determine how much you can reasonably pay each month without compromising essential living costs or future tax obligations.

Step 4: Submit Your Application

Use the HMRC Time to Pay application service.

You may need your Unique Taxpayer Reference, bank account information and details of your income and expenditure.

If you cannot arrange payments online, contact HMRC directly.

Step 5: Maintain Your Repayments

Once approved, make the agreed instalments on time.

Keep confirmation of your arrangement and monitor your remaining balance.

If circumstances change, contact HMRC promptly to discuss whether your repayment schedule can be adjusted.

Does HMRC Charge Interest on Time to Pay?

Yes. An important consideration is that HMRC generally continues charging late-payment interest while an outstanding tax liability remains unpaid.

Even when a Time to Pay arrangement has been approved, interest normally accumulates on the remaining balance.

This means spreading your Self Assessment Tax Bill can increase the overall amount payable.

For example, someone repaying £10,000 over 12 months will generally pay more than £10,000 because interest accrues during the repayment period.

The precise amount depends on the interest rate, repayment dates and outstanding balance.

HMRC interest rates can change, so it is important to check the applicable rate when estimating repayment costs.

You can access the official HMRC late-payment interest rates.

Paying more than the minimum agreed instalment, where affordable and appropriately allocated, can reduce the period during which interest accumulates.

Therefore, Time to Pay provides flexibility but should not be confused with an interest-free payment facility.

Can Time to Pay Help You Avoid Late-Payment Penalties?

One significant advantage of arranging Time to Pay promptly is the possibility of avoiding certain late-payment penalties.

Under the established Self Assessment rules, penalties are generally calculated at 5% of the relevant unpaid tax at three stages:

• Thirty days after the payment deadline.
• Six months after the deadline.
• Twelve months after the deadline.

However, an acceptable Time to Pay arrangement can prevent relevant penalties arising during the period covered by the agreement.

According to HMRC’s official Time to Pay penalty guidance, a suitable arrangement proposed within 30 days of the payment deadline can prevent the relevant late-payment penalties.

Arrangements made later may still prevent subsequent penalties, but they do not automatically cancel penalties already incurred.

Importantly, penalties and interest are separate matters.

Even where an arrangement prevents late-payment penalties, interest generally continues accumulating.

Read the full Self Assessment late-filing and late-payment penalty rules.

What Happens If You Miss a Time to Pay Instalment?

Missing an agreed instalment can create additional complications, although HMRC does not necessarily cancel an arrangement immediately.

HMRC may contact you to understand why the payment was missed and whether a revised schedule would be appropriate.

However, repeated missed payments could result in the arrangement being withdrawn.

If your agreement is cancelled, HMRC may request immediate repayment of the outstanding balance.

Further collection action could also follow.

For example, if you lose employment income or experience an unexpected business expense, contact HMRC before your next payment becomes due.

Explain the change in circumstances and provide an updated financial assessment.

HMRC’s guidance on changing a payment plan explains that arrangements may sometimes be extended or shortened when circumstances change.

Maintaining communication with HMRC is essential when experiencing repayment difficulties.

Can You Apply If You Owe More Than £30,000?

Yes. Owing more than £30,000 does not automatically prevent you from obtaining an HMRC Time to Pay arrangement.

Although this amount has traditionally been the threshold for the standard online Self Assessment facility, larger liabilities may be considered through direct discussions with HMRC.

For substantial debts, HMRC may request more detailed information about your finances.

This could include business cash-flow forecasts, household expenditure, savings, available assets and anticipated income.

HMRC may also question how the outstanding liability arose and what steps you have taken to prevent further arrears.

A realistic repayment proposal supported by accurate financial information is particularly important.

Where the debt is substantial or the circumstances are complicated, professional accounting assistance may help you prepare an appropriate proposal.

However, approval remains at HMRC’s discretion.

Can You Reduce Your Payments on Account Instead?

Before applying for Time to Pay, consider whether your Self Assessment Tax Bill includes payments on account that may be unnecessarily high.

Payments on account are advance payments towards your next tax liability, generally based on your previous year’s relevant tax calculation.

If your income has decreased, you may be entitled to reduce these advance payments.

For example, suppose your previous year’s liability was £8,000.

Your payments on account would normally be £4,000 each.

If your estimated liability for the following year is only £4,000, you may be able to reduce each payment to £2,000.

This could substantially ease your immediate financial pressure.

However, reductions must be based on reasonable estimates.

If your eventual liability is higher than the reduced amounts, HMRC may charge interest on the underpayment.

You can review HMRC’s payments on account guidance or use the official SA303 reduction procedure.

This option is particularly relevant for sole traders experiencing reduced profits or landlords whose taxable rental income has fallen.

HMRC Time to Pay vs Budget Payment Plan

Although both facilities allow regular payments, they serve different purposes.

Time to Pay is designed to help taxpayers manage outstanding tax liabilities they cannot settle immediately.

A Budget Payment Plan, by contrast, allows eligible taxpayers to make voluntary weekly or monthly payments towards their next Self Assessment bill.

For example, someone expecting a £6,000 annual tax liability might contribute £500 monthly towards their upcoming payment.

By saving gradually through HMRC’s payment system, they may reduce the amount outstanding when the payment deadline arrives.

To establish a Budget Payment Plan, you generally need to be up to date with your previous Self Assessment payments.

The arrangement does not automatically change statutory payment deadlines.

If your accumulated contributions are insufficient, you must still pay the remaining balance when due.

More information is available through HMRC’s Budget Payment Plan guidance.

For taxpayers with predictable income, regular advance payments can be an effective way to avoid future cash-flow difficulties.

What If HMRC Rejects Your Payment Proposal?

HMRC may reject a Time to Pay application if the proposed instalments are unrealistic or the information supplied is insufficient.

A refusal does not necessarily mean there are no further options.

You may be able to review your budget, identify additional available funds or present a revised proposal supported by clearer financial information.

If your income fluctuates, provide evidence explaining seasonal variations or expected future receipts.

You should also check that your tax calculation is accurate and that all legitimate allowances and deductions have been included.

An appropriately authorised accountant can assist with reviewing liabilities, preparing forecasts and communicating with HMRC.

However, any revised proposal must remain realistic.

Agreeing to unaffordable instalments simply to obtain approval could create greater financial difficulties later.

Can HMRC Take Enforcement Action for Unpaid Tax?

If you ignore outstanding tax liabilities or fail to engage with HMRC, enforcement action may eventually follow.

Depending on the circumstances, HMRC may use debt collection agencies, recover amounts from earnings, take action against certain assets or pursue legal proceedings.

In serious cases, insolvency proceedings may also be considered.

The consequences can be financially significant, particularly where collection costs or further liabilities arise.

HMRC normally attempts to contact taxpayers before taking stronger recovery action.

Its official guidance on what happens if you do not pay HMRC explains the potential collection procedures.

Where possible, discussing payment difficulties early provides a better opportunity to find a manageable solution.

Ignoring HMRC correspondence should never be treated as an effective strategy.

How to Avoid Future Self Assessment Tax Problems

Although Time to Pay can provide temporary relief, preventing future tax difficulties is equally important.

Consider implementing the following financial habits.

Set aside money for tax. Transfer an appropriate percentage of your earnings into a dedicated savings account.

Prepare your tax return early. Knowing your liability months before the deadline provides additional time to plan.

Review your payments on account. Ensure advance payments reflect your expected income where reductions are justified.

Maintain accurate records. Reliable bookkeeping makes it easier to calculate profits and identify legitimate deductible expenditure.

Monitor your cash flow. Consider upcoming tax payments alongside business expenses and personal financial commitments.

Seek professional advice. An accountant can help estimate tax liabilities and identify potential cash-flow pressures before deadlines approach.

HMRC also recommends filing your Self Assessment return early, allowing more time to understand and budget for the amount due.

Consistent tax planning can substantially reduce the risk of unexpected liabilities.

Frequently Asked Questions

Can I spread my Self Assessment Tax Bill over 12 months?

Potentially, yes. Eligible taxpayers may arrange monthly instalments through HMRC. The repayment period depends on eligibility, affordability and whether the arrangement is made online or negotiated directly.

Does HMRC automatically approve payment arrangements?

No. HMRC considers your financial circumstances, outstanding liabilities and ability to maintain repayments before agreeing to an arrangement.

Can I apply before my Self Assessment payment deadline?

You should contact HMRC as soon as you anticipate payment difficulties. The standard online facility may have specific eligibility conditions, but early discussions can help establish your options.

Will Time to Pay stop interest charges?

No. Late-payment interest generally continues accruing on outstanding tax until the liability has been settled.

Can I repay my outstanding balance early?

Yes. Paying outstanding amounts sooner can reduce the interest charged. Ensure additional payments are correctly allocated and check any necessary changes to your agreed instalments.

Can an accountant arrange Time to Pay for me?

An appropriately authorised accountant can assist with reviewing the liability, preparing supporting financial information and communicating with HMRC about payment difficulties.
