HMRC Income Tax Arrears

Falling behind on your income tax payments can feel overwhelming, especially when HMRC is the creditor. If you’ve missed a Self Assessment deadline, received an unexpected tax bill or your circumstances have changed and payments have become unaffordable, HMRC income tax arrears can quickly become difficult to manage.

HMRC has some of the strongest debt recovery powers of any creditor in England, Wales, and Northern Ireland. Unlike a catalogue company or credit card provider, HMRC can take action without going to court, so acting sooner rather than later is essential.

If you’re dealing with HMRC tax debt, you’re not without options. An Individual Voluntary Arrangement (IVA) is one formal debt solution that can include your tax debt alongside other personal and business debts, consolidating what you owe into one affordable monthly payment and giving you a clear path forward.

What are HMRC Income Tax Arrears?

HMRC income tax arrears are money owed to HM Revenue and Customs when you haven’t been able to pay your tax by the required deadline. This can happen through the Self Assessment system, where you’re responsible for calculating and paying your own tax, or through an underpayment identified by HMRC on a PAYE tax code.

Penalties and interest begin to build from the moment a payment is missed, which means the amount you owe can grow quickly if left unaddressed.

However, income tax arrears can be included in formal personal debt solutions. As an unsecured creditor in personal insolvency proceedings, HMRC can participate in an IVA, which means your tax debt could be consolidated alongside other debts into one manageable monthly payment.

Types of HMRC Income Tax Arrears

Self Assessment Arrears

If you’re self-employed, a company director or you have income that isn’t taxed at source, you’ll need to complete a Self Assessment tax return each year. If the tax owed isn’t paid by the 31 January deadline, HMRC will issue penalty notices and charge interest on the outstanding balance. Self Assessment arrears are the most common form of income tax debt.

PAYE Underpayment

Employees pay income tax through the Pay As You Earn (PAYE) system, where tax is deducted automatically by an employer. However, if your tax code was incorrect, you had more than one job at the same time or you received untaxed income during the year, HMRC may calculate that not enough tax was collected. They’ll then issue a Simple Assessment or a P800 letter asking you to pay the shortfall.

Payments on Account

Self Assessment taxpayers are often required to make advance payments towards the following year’s tax bill, known as payments on account. These are due in January and July each year. If your income dropped but your payments on account weren’t reduced, or if you simply couldn’t afford them, the unpaid amounts become arrears in their own right.

Penalties and Interest

HMRC adds automatic penalties for late filing and late payment, as well as daily interest on unpaid tax. These charges can significantly increase the amount you owe beyond the original tax bill, particularly if the debt has been outstanding for some time.

Causes of HMRC Income Tax Arrears

HMRC income tax arrears can build up for a number of reasons, and it doesn’t always come down to carelessness or overspending.

Not Setting Aside Enough for Your Tax Bill

Without an employer deducting tax at source, it can be easy to spend money that should have been saved for your tax bill. This is one of the most common reasons self-employed people fall into income tax arrears. By the time the January deadline arrives, the funds simply aren’t there.

Poor Record Keeping

Keeping accurate records of your income and expenses throughout the year is essential for getting your taxes right. Gaps in record keeping can lead to errors in your tax return, missed deductions or an inaccurate picture of what you owe, all of which can result in an unexpected bill from HMRC.

Additional or Unexpected Income

Income from renting out a property, selling assets, freelance work or other sources outside your main employment can create a tax liability you weren’t expecting. If this income isn’t declared or the tax isn’t set aside, arrears can build up quickly.

Changes in Circumstances

Illness, job loss, relationship breakdown or a sudden drop in income can all make it impossible to pay a tax bill that was manageable when it was first issued. Life doesn’t always go to plan, and HMRC arrears can mount up through no fault of your own.

Using Tax Money to Cover Other Bills

When cash flow is tight, it can be tempting to dip into money set aside for tax to cover more immediate expenses. This is a short-term fix that creates a longer-term problem, as the tax bill doesn’t go away, and HMRC will pursue what’s owed.

Changes in Business Income

Fluctuating income is a reality for many self-employed people. A strong year can be followed by a difficult one, and if your payments on account were based on higher earnings, you may struggle to meet them when income drops. Managing these swings without building up arrears takes careful planning.

If you’re dealing with HMRC tax debt, you’re not without options. A self-employed IVA can include your HMRC tax debt alongside other personal and business debts, consolidating what you owe into one affordable monthly payment while allowing you to carry on trading.

What happens if I don't pay my HMRC income tax arrears?

If you fall behind on income tax payments, HMRC will usually follow these stages:

Payment reminders: HMRC will write to you asking you to pay the outstanding amount, including any penalties and interest that have already been added.

Formal demand: If the debt remains unpaid, HMRC will issue a formal notice requiring payment. At this stage the debt can be referred to HMRC’s debt management teams.

Debt collection agency: HMRC may pass your debt to an external debt collection agency to pursue payment on their behalf.

Field force officers: HMRC can send enforcement officers to your home or business to take control of goods, which can then be sold to recover what you owe.

County Court Judgment: HMRC can apply to court for a CCJ, which gives them further legal tools to recover the debt and will appear on your credit file.

Bankruptcy petition: As a last resort, HMRC can petition for your bankruptcy if the debt remains unpaid. This is one of the most serious outcomes and has significant long-term consequences.

Ignoring letters and demands from HMRC will make your situation worse. If you respond to them early, HMRC may agree a Time to Pay arrangement, a payment plan that lets you clear the debt in instalments. Speaking to a debt consultant or Insolvency Practitioner can also help you understand your options before enforcement action begins.

Will HMRC income tax arrears affect my credit score?

HMRC income tax arrears don’t automatically appear on your credit file in the same way that a missed credit card, utility bill or loan payment would. HMRC doesn’t report debts directly to the main credit reference agencies, so simply having a tax bill outstanding won’t show up on your credit report.

However, if HMRC takes enforcement action, the consequences can affect your credit score:

County Court Judgments will appear on your credit file for 6 years and can make it difficult to access credit, mortgages or other financial products
Bankruptcy stays on your credit file for 6 years from the date of the order and has serious long-term implications for your finances
A charging order on your property, which HMRC can apply for following a CCJ, will also be recorded and affect your ability to remortgage or sell

The key is to act before enforcement reaches these stages. If you contact HMRC early or explore formal debt solutions such as an IVA, you’re more likely to resolve the debt before it creates lasting damage to your credit file.

Can HMRC income tax arrears be written off?

It’s possible to have a portion of your income tax debt written off through a formal debt solution, but the debt won’t disappear on its own. You’ll need to take action.

Unlike some consumer debts, this type of tax arrears doesn’t become statute-barred in the same way. HMRC operates under tax legislation rather than the standard Limitation Act, which means they have longer to pursue what’s owed and the usual 6-year rule doesn’t apply in the same way.

However, formal personal insolvency solutions can result in a proportion of your income tax debt being written off. Subject to creditor approval, an IVA could write off up to 73% of your qualifying debt once you’ve completed the arrangement.* The exact amount depends on your circumstances and what your creditors agree to.

If you find yourself struggling in this situation, speaking to a debt consultant or Insolvency Practitioner is a sensible first step. They can review your situation and help you understand which debt solutions are available to you.

Debt Solutions for HMRC Income Tax Arrears

If you’re struggling with income tax arrears, there are lots of formal debt solutions that can help you deal with what you owe and regain control of your finances.

Individual Voluntary Arrangement (IVA)

An IVA is a formal, legally binding arrangement with your creditors that lets you bring all of your qualifying debts, including your tax arrears, into a single monthly payment you can afford. Your Insolvency Practitioner negotiates the terms with HMRC and your other creditors on your behalf. Once the IVA is in place:

HMRC is legally prevented from taking any further enforcement action
All interest and penalties stop increasing from the date of approval
Your monthly payment is set at a level based on your actual income and outgoings
Any qualifying debt that remains at the end of the arrangement is written off, subject to creditor approval**

An IVA is worth considering if your total unsecured debt is £7,000 or more, you have a steady income and something left over each month after covering essential costs. If you own a property, the equity you hold may determine if your IVA runs for 5 or 6 years.

Debt Relief Order (DRO)

If your total debt is under £50,000, your assets are limited and you have very little income left after covering essentials, a DRO could provide relief. Your tax arrears can be included, the arrangement pauses your debts for 12 months, and if your financial position hasn’t changed by then, everything included is cleared. Applying for a DRO is now free in England and Wales.

Debt Management Plan (DMP)

A DMP allows you to make lower payments each month across your debts based on what you can afford. It’s an informal arrangement with no legal standing, which means HMRC retains the right to contact you and continue adding interest throughout. It’s generally better suited to people facing temporary financial pressure rather than debts they have no realistic prospect of clearing.

Bankruptcy

Bankruptcy can clear income tax arrears and most other unsecured debts, typically within 12 months. It’s a serious step that can result in the sale of assets and carries a 6-year mark on your credit file.

Learn More

Breathing Space

The Breathing Space scheme provides 60 days of protection during which HMRC must halt enforcement action and can’t add further interest or penalties to your income tax debt. This gives you time to get proper advice and work out a longer-term plan without the pressure of active creditor contact.
