Remortgage to Pay a Tax Bill

Why Homeowners Remortgage to Pay Tax Bills

Tax bills can arise for many reasons, and they are not always predictable. Self-employed individuals and company directors often face large self-assessment bills, while selling a second property or receiving an inheritance can trigger unexpected tax liabilities.

Common types of tax bills that lead homeowners to consider remortgaging include:

• Self-assessment income tax — particularly large balancing payments or payments on account
• Capital gains tax (CGT) — arising from the sale of a second property, shares or other assets
• Inheritance tax (IHT) — payable on estates above the nil-rate band threshold
• Corporation tax — for company directors who may need to settle liabilities personally
• VAT arrears — for business owners who have fallen behind on their obligations

HMRC charges interest on late payments and can impose penalties that escalate over time. If you cannot pay your tax bill promptly, the amount you owe can increase significantly. Remortgaging allows you to clear the debt in full and replace it with a mortgage payment that may be more manageable on a monthly basis.

It is worth noting that while remortgaging can solve the immediate problem, you are effectively converting an unsecured debt into one secured against your home. This is a significant decision that should not be taken lightly, and professional financial advice is strongly recommended before proceeding.

HMRC Payment Plans and Time to Pay Arrangements

Before committing to a remortgage, it is important to understand that HMRC offers its own payment arrangements for taxpayers who are struggling to pay on time.

A Time to Pay (TTP) arrangement allows you to spread your tax bill over a period of up to 12 months, though longer periods may be agreed in certain circumstances. You can apply for a TTP arrangement by contacting HMRC directly, and in some cases, you can set one up online for self-assessment debts of up to £30,000.

The advantages of a Time to Pay arrangement include:

• No need to secure the debt against your property
• Quick to arrange compared to a remortgage
• HMRC may agree to pause enforcement action while the plan is in place
• Interest is charged at a lower rate than many commercial loans

However, HMRC interest is not always lower than mortgage rates, and the repayment period is typically much shorter. If your tax bill is substantial — tens of thousands of pounds or more — the monthly payments under a TTP arrangement may still be unaffordable.

In these situations, remortgaging can provide a longer repayment period and lower monthly payments, even though you will pay more in total interest over the life of the loan. Comparing the total cost of both options with a financial adviser is the best approach.

It is also worth considering that HMRC may decline a TTP request if they believe you have assets — such as property equity — that could be used to settle the debt. Having explored and been refused a TTP arrangement may actually strengthen your case for remortgaging, as it demonstrates you have considered all available options.

How the Remortgaging Process Works for Tax Bills

Remortgaging to pay a tax bill follows the same general process as any other remortgage, though there are some specific considerations to be aware of.

Step 1: Assess your equity position. You need to know how much equity you have in your property. This is the difference between your home's current market value and your outstanding mortgage balance. Most lenders will allow you to borrow up to 85-90% of your property's value.

Step 2: Check your current mortgage terms. If your existing mortgage has early repayment charges (ERCs), the cost of switching could be significant. Calculate whether the benefit of remortgaging outweighs these charges.

Step 3: Speak to a mortgage adviser. A whole-of-market adviser can search across hundreds of lenders to find a deal that suits your circumstances. They will also advise on how much you can realistically borrow based on your income and commitments.

Step 4: Declare the purpose of the funds. When applying, you will need to tell the lender that the additional borrowing is to pay a tax bill. Most lenders will accept this as a legitimate purpose, though some may ask for supporting documentation such as your HMRC statement of account.

Step 5: Complete the remortgage. Once approved, the process typically takes four to eight weeks. On completion, the additional funds are released and you can use them to settle your HMRC liability immediately.

Timing is critical when dealing with tax bills. If your payment deadline is approaching, let your adviser know so they can prioritise your application. In the meantime, it may be worth contacting HMRC to explain that you are arranging funds, as this can sometimes prevent enforcement action being initiated.

Costs, Risks and Important Considerations

While remortgaging can provide relief from an immediate tax problem, it is essential to understand the full financial picture before proceeding.

Total cost of borrowing: By spreading your tax bill over your mortgage term — which could be 20 or 25 years — you will pay significantly more in total interest than you would by settling the bill directly or through a short-term arrangement. For example, adding £30,000 to a 25-year mortgage at 5% interest would cost approximately £22,500 in interest alone.

Your home is at risk: Unlike an unsecured tax debt, a mortgage is secured against your property. If you cannot keep up with repayments, your home could be repossessed. This is a fundamental change in the nature of the debt that should not be underestimated.

Impact on loan-to-value ratio: Increasing your mortgage balance raises your LTV, which could affect your ability to access the best interest rates in future. If property values fall, you could find yourself in a position where you owe more than your home is worth.

Fees and charges: Remortgaging involves costs including arrangement fees, valuation fees, and legal fees. Some deals include free legal work and valuations, but arrangement fees can range from a few hundred to several thousand pounds.

Tax advice: If your tax bill is the result of a complex situation — such as a business dispute or an HMRC investigation — it is important to ensure the underlying tax issue is fully resolved before remortgaging. There is little point in releasing equity to pay a bill that may change as a result of ongoing negotiations.

A qualified financial adviser can help you weigh up these factors and determine whether remortgaging is genuinely the best solution for your specific circumstances.

Alternatives to Remortgaging for Tax Bills

Remortgaging is not the only way to fund a large tax payment. Depending on your circumstances, one of the following alternatives may be more appropriate.

HMRC Time to Pay arrangement: As discussed above, this allows you to spread payments over a shorter period without securing the debt against your property. Contact HMRC on 0300 200 3835 to discuss your options.

Personal loan: For smaller tax bills, an unsecured personal loan could be simpler and quicker to arrange. Interest rates will typically be higher than a mortgage, but you avoid tying the debt to your home and the repayment period is shorter.

Secured loan (second charge mortgage): This allows you to borrow against your property without changing your existing mortgage. It can be useful if you have a competitive rate you do not want to lose or if early repayment charges make remortgaging expensive.

Further advance: Your current lender may offer additional borrowing on your existing mortgage without requiring a full remortgage. This can be quicker, though the interest rate may differ from your current deal.

Savings or investments: If you have savings, ISAs or other investments, it may be more cost-effective to use these rather than taking on additional debt. Consider the opportunity cost and any tax implications of withdrawing investments.

Business funding: If the tax bill relates to your business, you may be able to arrange commercial finance, a business loan or an overdraft facility to cover the payment.

Each option has different implications for your overall financial position. A comprehensive review with a financial adviser will help you identify the most suitable and cost-effective approach.

Getting Professional Help with Tax-Related Remortgages

Dealing with a large tax bill and a remortgage simultaneously can be complex. Getting the right professional support makes the process significantly smoother and helps ensure you make informed decisions.

A mortgage adviser who has experience with tax-related borrowing can help you navigate the application process, find a lender who is comfortable with the purpose of the funds, and secure the best deal available for your circumstances.

An accountant or tax adviser can help you understand the nature of your tax liability, check that the amount demanded by HMRC is correct, and advise on whether any reliefs or allowances might reduce the bill. They can also help with future tax planning to reduce the risk of a similar situation arising again.

If HMRC has initiated enforcement action — such as a distraint notice or a charging order against your property — a tax investigation specialist may be needed to negotiate on your behalf and protect your interests.

The key is to act quickly. HMRC penalties and interest charges accumulate over time, so the sooner you address the problem, the less it will cost you. Even if you are not sure whether remortgaging is the right option, speaking to an adviser early gives you the information you need to make a confident decision.

Many mortgage advisers offer free initial consultations, so there is no cost in exploring your options. The peace of mind that comes from having a clear plan to deal with your tax liability is invaluable.
