If you run a VAT-registered limited company in the UK, you will know the rhythm: you collect VAT on every sale, you reclaim VAT on every purchase, and every quarter (or month) you pay HMRC the difference. The arithmetic is straightforward; the cashflow is not. A VAT bill that lands the same week as payroll, supplier deposits and a slow-paying customer is a genuine problem. This article is the practical guide.
First — what HMRC will do
HMRC’s “Time to Pay” arrangement is a real, formal option for businesses that can demonstrate genuine short-term cashflow difficulty. You phone the Business Payment Support Service (0300 200 3835) BEFORE the payment deadline, explain the position, and agree a phased repayment plan — typically over 3-12 months. The arrangement carries interest at HMRC’s published rate (currently around 7.75%, recalculated periodically) and a 5% surcharge if the original payment was missed first.
This is the cheapest option in almost every case. Ring HMRC before you ring anyone else.
Where HMRC won’t help
HMRC won’t engage on Time to Pay if:
- You’ve already had a Time to Pay arrangement in the recent past for the same kind of bill.
- The position isn’t a genuine short-term cashflow squeeze (i.e. the business isn’t actually generating the cashflow it’ll need to repay).
- You missed the deadline already and didn’t make contact — in that case you’re into surcharges and a hardened position.
If HMRC won’t engage, short-term finance is the next real option.
Where short-term finance fits
A short-term business loan from a fintech lender can bridge a single VAT bill. The mechanics: take the loan to cover the bill, pay HMRC on time, then repay the loan from the next 4-12 weeks of trading. You avoid HMRC surcharges, you keep your filing record clean (important for future Time to Pay if you ever need it), and you have a defined repayment schedule.
The cost comparison is roughly: HMRC Time to Pay at 7.75% APR vs a fintech short-term loan at much higher headline APR but spread over 30-90 days. On a £3,000 VAT bill, the £ cost is usually in the £100-£250 range either way — close enough that the deciding factor is often “can I get HMRC to engage”.
What we’d argue against
Two things we wouldn’t recommend: paying a VAT bill on a personal credit card (you almost always lose protections and the % rate is high), and ignoring the bill in the hope that the next month’s trading covers it (HMRC surcharges escalate, your bank rating deteriorates, and the conversation gets harder).
How to make the call
- Calculate the £ bill, the date it’s due, the days between now and then.
- Phone HMRC’s Business Payment Support Service. Ask about Time to Pay. Note their answer.
- If they decline, get a short-term-loan quote that matches the cashflow shape (the Credicorp business loans calculator will quote against a 30/60/90-day term).
- Compare the £ totals and the repayment shapes. Pick whichever costs less AND fits the next 90 days of cashflow.
