Corporation Tax Bridge Loans for UK SMEs
A corporation tax bridge loan lets a UK limited company borrow a short-term lump sum to meet its HMRC corporation tax bill on time, then repay over a fixed term of three to twelve months. It preserves working capital, avoids late-payment interest, and keeps the company's compliance record with HMRC clean.
What is a corporation tax bridge loan?
A corporation tax bridge loan is a short-term unsecured or lightly secured facility taken out specifically to fund a company's corporation tax liability before or on the due date set by HMRC, typically nine months and one day after the accounting period ends. The loan amount mirrors the tax bill, and repayment is spread over three to twelve monthly instalments.
Unlike an overdraft, the facility is ring-fenced for a single purpose, which makes underwriting straightforward and approval decisions fast. Specialist lenders can often release funds quickly once they have a signed tax computation or accountant's letter confirming the liability. Interest is charged only on the outstanding balance, so early repayment reduces the total cost. The FundBiz enquiry form is for limited companies, LLPs and partnerships with four or more partners.
Why SMEs use tax bridging rather than savings
Many profitable companies arrive at their tax payment date with cash tied up in stock, outstanding invoices or a recent capital purchase, making a dedicated bridge loan a practical tool rather than a sign of distress. Retaining working capital in the business often produces a better return than holding a large tax reserve in a low-yield current account.
If the business can deploy that capital at a higher margin than the cost of borrowing, funding the tax bill at a fixed monthly cost can be financially rational. The key is comparing the net cost of the loan against the opportunity cost of liquidating working capital or drawing down a more expensive revolving facility.
HMRC late-payment interest versus loan cost
Failing to pay corporation tax on time triggers HMRC late-payment interest, charged at the bank base rate plus 4 percentage points (currently 7.75% per annum) and calculated daily on the overdue amount. For a sixty thousand pound bill that is three months late, the interest charge alone runs to over a thousand pounds before any formal recovery proceedings begin.
A short-term bridge loan for the same amount and period typically carries a monthly fee or interest rate that, when annualised, depends on the lender and the company's credit profile (see our indicative business loan interest rates ranges). At first glance that looks more expensive, but the bridge loan is repaid in instalments rather than as a lump sum, smoothing cash flow, and it keeps the company's HMRC compliance record intact, which matters if a future HMRC interaction becomes necessary.
Which lenders offer corporation tax bridging in the UK?
Several specialist and alternative lenders offer tax loan products for UK limited companies. The market breaks into three categories: dedicated tax loan providers, broader short-term business loan platforms, and accountant-referred facilities. Dedicated providers offer tax-specific products requiring little more than the CT600 computation and three to six months of bank statements. Broader platforms will fund a tax payment as part of a general working capital draw. Some accountancy practices have panel agreements and can refer clients directly. Challenger banks such as OakNorth and Allica Bank may consider larger facilities within a broader relationship banking context.

Eligibility and what lenders check
Lenders set their own minimum trading history, and larger unsecured facilities usually need a longer track record. The tax liability must be confirmed in writing, usually through a signed CT600 or an accountant's letter.
Lenders review three to six months of business bank statements to assess turnover and existing debt. A personal guarantee from the directors is standard for unsecured facilities. CCJs registered within the past 24 months can restrict access to mainstream lenders, though specialist brokers can route declined applications to a secondary panel. The company must be current on VAT and PAYE; an existing HMRC debt in these areas can count heavily against an application.

| Short-term loan platform | £5,000 to £500,000 | 24 to 48 months | 12 months | Yes |

Step by step
- Obtain the finalised corporation tax computation or a written liability confirmation from your accountant, showing the amount due and the deadline.
- Check your company's credit file via Companies House and a commercial credit reference agency to identify any CCJs before applying.
- Confirm all VAT and PAYE accounts with HMRC are current, as outstanding debts in these areas can count heavily against an application.
- Approach lenders or a broker and share your bank statements, filed accounts and the tax liability letter.
- Compare at least two or three lender quotes on total repayable, not just headline rate.
- Sign the agreement, confirm funds have cleared, then make the HMRC payment and keep written confirmation of settlement.
- Set up the monthly repayment and ensure the loan interest is coded correctly in your accounting software from the outset.
This is an illustrative scenario, not a real client case. A manufacturing limited company had a corporation tax bill of forty-eight thousand pounds due in November. Cash was committed to a large raw materials order placed the month before. The finance director arranged a nine-month bridge loan through a broker, approved in 18 hours, at a fixed monthly cost. The HMRC payment was made on time and the working capital remained intact to fulfil the materials order.
Frequently asked questions
Can I use a corporation tax bridge loan if my company has a CCJ?
A CCJ registered in the past 24 months will usually cause a decline at mainstream lenders. Specialist lenders can still consider adverse credit, though rates are higher. It is worth comparing the cost against an HMRC Time to Pay arrangement before proceeding.
Is a personal guarantee always required for a tax bridge loan?
For unsecured facilities below half a million pounds, most UK alternative lenders require at least one director to provide a personal guarantee, which means personal assets could be at risk if the company defaults. Some lenders accept a debenture over company assets as partial security in place of a full guarantee, particularly on larger facilities, negotiated case by case.
How does a tax bridge loan affect my company's credit rating?
The loan appears as a short-term liability on your balance sheet and is recorded with commercial credit reference agencies once the lender files the data. Provided repayments are on time, the facility can have a neutral or modestly positive effect. Missed repayments register as adverse data and make future borrowing harder or more expensive.
What is the difference between a corporation tax bridge loan and HMRC Time to Pay?
HMRC Time to Pay is a direct instalment arrangement with HMRC at its late-payment interest rate with no arrangement fee. A bridge loan involves external borrowing at a higher rate but delivers the full payment to HMRC on time, preserving the compliance record. Time to Pay is worth exploring first, but HMRC does not guarantee approval.
How quickly can I receive funds from a corporation tax bridge loan?
Specialist lenders can often release funds quickly once a complete application is submitted, including bank statements, the tax liability letter and signed agreement documents. Delays usually arise from incomplete documentation rather than underwriting complexity. If the deadline is imminent, applying through a broker with existing lender relationships shortens the process.
Is the interest on a corporation tax bridge loan tax deductible?
For a company, interest is dealt with under the loan relationship rules. Borrowing to pay corporation tax may not count as a trading purpose, but interest on it can still be relieved as a non-trading loan relationship debit, subject to the usual restrictions (HMRC Corporate Finance Manual, CFM30170). Confirm the position with your accountant.
