Quick answer
UK SMEs can fund a tax bill through dedicated VAT or corporation-tax loans, general unsecured term loans, merchant cash advances, or - often best - an HMRC Time to Pay arrangement. Time to Pay is usually the cheapest option when you can demonstrate ability to clear the debt over up to twelve months. Specialist tax-funding products work well when cashflow is otherwise healthy and you want to preserve working-capital lines.
Why tax bills create a specific cashflow problem
Corporation tax, VAT and PAYE bills land on fixed dates regardless of how the trading month went. Unlike supplier invoices, you cannot renegotiate the date and you cannot stretch the terms. HMRC charges interest and, after a while, penalties. The result is a recurring, predictable cashflow squeeze that catches SMEs out more than almost any other working-capital pinch.
Most tax-bill funding decisions come down to a choice between paying HMRC interest (Time to Pay), borrowing externally to pay HMRC in full, or some combination. The right answer depends on the size of the bill, the urgency, and whether the underlying cashflow is sustainable.
Time to Pay (TTP)
HMRC's Time to Pay arrangement spreads a tax bill over a set period, typically up to twelve months for SMEs. There is no formal credit search; HMRC wants to see that you can realistically meet the agreed instalments. Interest is charged at HMRC's published rate, which is usually below typical commercial finance rates but not always - check the current rate before assuming.
TTP is administratively light, does not show up on commercial credit bureaus the same way a new loan does, and preserves your working-capital lines for other uses. The trade-off is that HMRC will not agree to extended terms repeatedly without good reason, and an unmet TTP can damage future engagement with HMRC.
Specialist VAT and corporation-tax loans
Several UK lenders offer short-term loans specifically for tax bills, with terms typically aligned to the next quarter or year. They tend to decision quickly because the use of funds is clear and the repayment is short. Costs vary, but they are often priced more competitively than a generic unsecured loan because the risk profile is constrained.
These products work well when the bill itself is one-off (a strong year producing a big corporation-tax payment) and cashflow over the next three to twelve months is healthy. They suit businesses that want to keep their existing working-capital facility free for the rest of the operation.
When to use other products
A general unsecured term loan can fund a tax bill alongside other working-capital needs, particularly when the bill is symptomatic of a broader cashflow pinch rather than a one-off event. An MCA can cover an urgent VAT or PAYE bill in days if you have card revenue, but the effective cost is higher.
Invoice finance against unpaid sales can be a strong route if the underlying cashflow problem is debtor delay rather than poor margin. Funding a tax bill from cash that is already earned but not yet collected is structurally cheaper than borrowing it from scratch.

- MCAs work for urgent bills but cost more.

Frequently asked questions
- Will applying for a tax loan hurt my credit?
- Like any commercial loan, it usually involves a hard search. The loan itself, once active, sits on your business credit file.
- Can I get a tax loan with bad credit?
- Sometimes, but pricing tightens and a personal guarantee is more likely. Some lenders consider adverse with explanation; others do not.
- Is Time to Pay automatic?
- No. You have to request it through HMRC's online service or by phone. They will ask about your ability to meet the schedule.
- What happens if I cannot pay HMRC at all?
- Engage early. HMRC's enforcement tools are significant, but they are also more flexible when contacted proactively than when ignored.
