Time to Pay: What Happens When You Cannot Pay the Bill

HMRC will spread a bill over instalments in many cases. Interest still runs — but an agreed arrangement generally stops the escalation that follows non-payment.

A tax bill that cannot be paid produces a particular kind of paralysis. The bill is known, the deadline is known, and the instinct is to say nothing until something changes. That instinct is the expensive one, because HMRC's response to non-payment is very different from its response to a request for time.

Time to Pay is the formal arrangement for spreading a liability over instalments. It is routine, it is granted in large numbers every year, and it exists because HMRC would rather collect a bill slowly than not at all.

Ask before the due date, not after. An arrangement agreed before a payment falls due is straightforward. One negotiated after enforcement has started is harder, and by then penalties may already have been charged.

What HMRC Will Ask

Propose a schedule you can actually meet. A plan agreed optimistically and broken in month three is worse than a longer plan honoured, because a defaulted arrangement is much harder to replace.

Getting the Bill Right First

Before arranging to pay something, check that it is owed. Two situations recur:

  1. Payments on account calculated from a better year. Where your income has genuinely fallen, they can be reduced — see payments on account. Reducing them too far attracts interest, so base it on a realistic estimate.
  2. A P800 built on estimated figures. Savings interest in particular is sometimes estimated rather than actual — see the P800 calculation.

Correcting an overstated liability is a better outcome than arranging to pay it in instalments.

If You Live Abroad

Living overseas does not exclude you from an arrangement, and it does not put a UK debt out of reach either — the UK has recovery arrangements with a number of jurisdictions and a liability does not lapse because you moved. The practical issues are the same ones that affect everything else about dealing with HMRC from abroad: making payments cheaply and on time, and being reachable. See paying HMRC from abroad and HMRC online access from abroad.

Beware Who You Ask for Help

Tax debt attracts firms offering to negotiate on your behalf for a fee, some of which do little that you could not do yourself in a phone call. Before paying anyone, try the direct route: HMRC has a dedicated line for payment problems and self-serve options for smaller amounts. If the situation is genuinely complex, an accountant or a free debt advice charity is a better first call than an unsolicited approach.

Frequently Asked Questions

Will HMRC let me pay in instalments?

Often, yes. Time to Pay arrangements are routine and granted in large numbers each year. HMRC would rather collect a bill over time than not at all, provided your returns are up to date.

Does interest stop under a Time to Pay arrangement?

No. Interest continues to accrue on the outstanding balance. What an arrangement generally avoids is late payment penalties and the escalation that follows non-payment.

What if I cannot afford the instalments I agreed?

Contact HMRC before you miss one. A defaulted arrangement is significantly harder to replace than an existing one is to renegotiate, so propose a schedule you can meet in the first place.

Can I get an arrangement if I live abroad?

Yes. Living overseas does not exclude you, and it does not put the debt out of reach either, since the UK has recovery arrangements with a number of jurisdictions.
