The plan is the easy part. Paying it from a British bank is not.

An agreement to pay a tax balance over time rather than in one go. Two forms exist: a short-term arrangement measured in days, and a long-term instalment agreement paid monthly. Both leave interest running on whatever remains outstanding.

The IRS sets the dividing lines on its payment plans page. A short-term plan pays the amount owed in 180 days or less, and individuals can apply online while owing less than $100,000 in combined tax, penalties and interest.

A long-term instalment agreement spreads monthly payments instead. Online application is available where you owe $50,000 or less in combined tax, penalties and interest and have filed all required returns.

So the short-term route carries the higher threshold and the shorter timescale. That combination suits someone waiting on a payment rather than someone rebuilding over a year.

For the long-term route, yes, and the IRS states that condition directly alongside the dollar threshold. Filing all required returns forms part of qualifying to apply online, which catches people whose whole reason for needing a plan is that several years went unfiled.

That catches people who came to us precisely because several years were outstanding.

The order is therefore fixed: catch up the filings, then arrange the payments. Our article on Streamlined filing covers the route back for anyone with years missing.

The IRS sets out the filing dates themselves on its when to file page, including the automatic extension for citizens abroad.

Nothing at all for the short-term plan, whether you apply online, by phone, by mail or in person. Setup fees do apply to the long-term agreement, varying with how you apply and how you choose to pay, though they stay modest against most balances.

Those fees are modest against most balances, and they are not the reason to choose one route over the other.

Interest matters more. It runs on the outstanding balance under either plan, so the shorter arrangement costs less overall.

Yes, and the thresholds do not shift because you live abroad. What shifts is the practicality of each step, starting with the online account most applicants use. Identity verification assumes American documents and credit histories, which British records do not always satisfy.

Identity verification assumes American documents and credit histories, so records held in Britain often fall short.

Where the online route will not complete, Form 9465 is the paper application for an instalment agreement.

Allow weeks rather than days for the paper route, and keep proof of posting.

This is the real obstacle from abroad, and it deserves settling before anything else. The IRS lists Direct Pay from a checking or savings account among its methods, which assumes an American account that many people living in Britain closed years ago.

Card payments work from anywhere and carry processing fees, which add up across twelve monthly instalments. The IRS lists every route on its payments page.

International wire transfer is possible and slower, with its own reference requirements.

So decide the mechanism before you commit to a monthly figure, because the cost of moving the money is part of the cost of the plan.

If you still have one, yes, at least until any plan finishes. It makes each monthly payment straightforward and avoids card processing fees entirely. Closing the last American account and then discovering you need it is the sequence we see most often.

Closing it and then needing it is the sequence we see most often.

Where none exists, price the card fees into the plan rather than discovering them later. Twelve payments with a percentage fee each time is a real number.

Remember that the account still counts towards your own foreign account reporting while it stays open, though a US account is not a foreign one for that purpose.

It reduces rather than removes them. The failure-to-pay charge continues at a lower rate while an instalment agreement is in place, and interest continues regardless of any arrangement. The failure-to-file penalty sits separately, and nothing about how you pay touches it.

The failure-to-file penalty is separate and is not affected by any payment arrangement.

That asymmetry is why filing on time matters even when you cannot pay. Our article on reasonable cause penalty relief covers when the IRS will drop a penalty altogether.

The agreement can terminate, the full balance becomes payable again, and collection activity resumes. Reinstating an agreement is possible and involves more administration than simply keeping the original one, so contact the IRS and revise the plan rather than missing a payment.

Reinstating an agreement is possible and involves more administration than keeping the original one.

Where circumstances change, contact the IRS and revise the plan rather than missing a payment. Revision is a normal process; default is not.

It affects what each instalment costs you rather than what it settles. The plan runs in dollars, and every payment converts from sterling at whatever rate applies that month, so an arrangement that felt comfortable in January can bite by June.

So a plan agreed comfortably in January can feel different in June.

Leave headroom in the monthly figure for that movement, particularly on a twelve-month arrangement.

Our guide to exchange rate rules covers how conversion works for the return itself.

Yes, and it is almost always worth doing. Interest accrues on the outstanding balance, so any early payment reduces the total cost of the arrangement. There is no advantage in sticking to a schedule once the money exists to clear it.

There is no advantage in sticking to a schedule once the money exists.

Where a lump sum arrives part way through, pay it against the balance and let the remaining instalments finish sooner.

Tell the IRS the payment is against the balance rather than a future instalment, and keep the confirmation. Misapplied payments are tedious to trace from abroad.

Not directly, because the two authorities operate independently and neither takes the other into account. You can hold arrangements with both at once. The one connection worth noting is credit timing, since a foreign tax credit follows tax actually paid.

The one connection is credit timing. A foreign tax credit follows tax actually paid, so spreading a bill across years changes when relief becomes available.

Mention any arrangement to whoever prepares the other return. It rarely changes the decision and it does change the paperwork.

Then the online route closes and the process becomes a conversation rather than a form. Larger balances can still be paid over time, though the IRS asks for financial disclosure first, so prepare real figures before making contact.

Financial disclosure is part of that, so prepare figures before making contact.

This is also the point at which professional help pays for itself, because the submission is substantive rather than administrative.

Work through this in order, because each step gates the next.

States run their own arrangements, on their own terms, and an IRS payment plan does nothing for them. Anyone who left America with a state balance outstanding may face two separate negotiations.

Each state publishes its own process, and the thresholds differ sharply between them.

Deal with the federal balance first, then the state. The federal position usually dominates the arithmetic.

Check whether the state considers you resident at all for the years in question. Sometimes the answer removes the balance rather than scheduling it.

Set up the payment so it leaves automatically wherever possible, and diary each instalment anyway. A missed payment from a time zone eight hours away takes longer to fix than to prevent.

Keep the agreement letter and every payment confirmation together.

Review the plan once the next return is filed, because a new balance can interact with the existing agreement.

In our practice, plans fail for administrative reasons far more often than financial ones.

Take an illustrative case. An American in Bristol files three late returns and ends up owing about $14,000 including penalties and interest.

The balance sits comfortably inside the online threshold for a long-term agreement, and all returns are now filed, so the application itself takes minutes.

Her difficulty lies in payment: no US account remains open, so card fees would apply monthly. She opts for a shorter plan with larger payments by wire. The figures are illustrative; the mechanics drove the decision.

First, applying for a long-term plan with returns still outstanding. Second, choosing a twelve-month plan without pricing the payment method.

Third, closing the last American bank account before the plan ends. Fourth, assuming an agreement stops penalties entirely.

Fifth, setting a monthly figure with no headroom for the exchange rate. Sixth, missing a payment rather than asking to revise.

Seventh, arranging an IRS payment plan while the next year's liability is already building. A plan settles what you owe today and nothing about what April will add to it.

We get the filings current first, because the long-term route depends on it, then work out which threshold your balance falls under. Only then do we look at the monthly figure.

Our US federal return service covers the returns, and we set out the payment mechanics for someone banking in Britain before you commit to anything.

Tell us the balance and which returns are outstanding, and we will set out the order.
