Why it can be the cheaper option

Missing a tax deadline means HMRC interest and potentially penalties, plus the risk of escalation. Borrowing to pay on time replaces those charges with the cost of the finance — which, for a short-term facility, can be less than the accumulating HMRC cost, especially once penalties are in play. It also keeps you in good standing with HMRC, which matters for future dealings. See using a loan to pay a tax bill.

The comparison to run

Weigh the total cost of financing the bill over the time you need against the total HMRC interest and penalties you would otherwise incur, plus the value of avoiding escalation. For a short delay the gap may be small; for a longer one, or where penalties apply, borrowing often wins clearly. Do the sum rather than assuming — see finance for a VAT bill and for corporation tax.

Doing it well

Match the finance to the bill: a short-term facility or loan sized to the tax due and repaid over a period your cash flow can manage. Do not stretch a one-off tax bill over years, paying interest long after the bill is settled. And treat a recurring inability to meet tax bills as a signal to look at the underlying cash flow, not just to keep borrowing. See planning around cash flow.

Compare the finance cost against HMRC's on the true cost calculator, and if it pays, apply.

Frequently asked questions

Is it better to borrow or arrange a Time to Pay with HMRC?

It depends on the cost of each. HMRC's own arrangements may carry interest too, so compare the total cost of a Time to Pay arrangement against financing the bill externally. Sometimes borrowing is cheaper and cleaner; sometimes an HMRC arrangement suits better. Run both totals, and factor in the value of keeping the finance and the HMRC relationship in good order.

Should I make a habit of borrowing to pay tax?

No — borrowing to meet a one-off tax squeeze is reasonable, but a recurring inability to fund tax bills points to a deeper cash-flow problem that more borrowing will not fix. If it keeps happening, address the underlying cash flow: set aside tax as it accrues, tighten credit control, or reassess pricing. Use finance as a bridge, not a permanent substitute for provisioning tax.
