The fee is $2,350. That is rarely the expensive part

Figures relate to tax year 2025-26 (UK) · 2025 (US)

The headline figure is easy to find. Giving up American citizenship carries an administrative fee of $2,350, which is among the highest consular charges levied anywhere in the world.

People budget for that number and stop. It is visible, it never changes, and it appears on every page about the subject. So it feels like the answer.

The real renunciation cost is the work that has to happen before you can attend the appointment at all. Five years of returns, a possible exit charge and a final year that nobody can prepare in an afternoon.

Key takeaways

• The consular fee is $2,350 and does not vary.
• Five years of US tax compliance must be in place first.
• Catch-up filing is usually the largest professional cost.
• The exit tax applies only to covered expatriates.
• A dual status final year and Form 8854 follow afterwards.
• You need another nationality before you can proceed.
• Twelve months is a realistic timeline from start to finish.

What is the total renunciation cost?

For a straightforward case with clean filings, usually the fee plus a few thousand pounds of professional work. For someone with years of missed returns and a complicated balance sheet, it can run well into five figures.

The spread is wide because only the fee stays constant. Everything else in the renunciation cost depends on how compliant you already are and how complex your assets have become.

According to IRS guidance on expatriation, the tax obligations run to the date you give up the citizenship and the final filings follow in the ordinary way. None of that work is optional.

Why does compliance drive the cost?

Because you must certify five years of American tax compliance to avoid becoming a covered expatriate. You make that certification under penalty of perjury, so it has to be true rather than convenient.

Someone already filing annually has very little to do. Someone who has never filed needs a catch-up submission covering several years of returns and six years of foreign account reports.

That gap is where the renunciation cost actually sits. Our guide to the cost of streamlined filing sets out what the catch-up itself typically runs to.

A worked example

The figures below are illustrative. They use round numbers so you can follow each step and substitute your own.

Sarah has lived in Edinburgh for fifteen years and has never filed an American return. She earns £55,000, holds a workplace pension and has about £180,000 in savings and investments.

She needs a streamlined submission first: three years of returns and six years of account reports. Because British rates exceed American ones, those returns produce almost no actual tax.

Her net worth sits well under $2 million and her average American tax is negligible, so she is not a covered expatriate and no exit charge arises. The deemed sale never applies to her.

Her total renunciation cost is the $2,350 fee, the catch-up work, and a dual status final return the following year. The tax itself is close to nothing.

What does the fee actually buy?

The administrative processing of your loss of nationality and the certificate that documents it. It covers the consular officer's time, the review in Washington and the issuing of the document.

It buys no tax advice, no filing and no part of the preparation. Those sit outside the consulate entirely and form the larger share of the renunciation cost.

The fee is payable at the appointment and is not refundable if you change your mind afterwards. It also applies per person, so a family pays it several times over.

The cost components compared

The table sets out where the money actually goes. Only the first row never moves.

When does the exit tax add to the bill?

Only where you are a covered expatriate, which means failing one of three tests on net worth, average tax liability or five year compliance. Most people in Britain fail none of them.

Where it does apply, the charge is a deemed sale of your worldwide assets with an exclusion covering roughly the first $890,000 of gain for 2025. Above that the tax can be substantial.

Our guide to the exit tax and Form 8854 covers the calculation. Modelling it early is what tells you whether the number is real.

How long does the process take?

Around twelve months from starting the work to holding the certificate, though the components run at very different speeds. The tax clean-up is the long pole and the appointment itself takes under an hour.

Appointment availability has historically been the bottleneck in London. Waiting lists have run to several months at times, and whichever date you accept fixes your expatriation date.

The certificate arrives some months after the appointment, because Washington reviews the file before issuing it. You are no longer American from the date of the oath regardless.

Can you do it from inside America?

No. Renunciation must take place abroad, in front of a diplomatic or consular officer, which is why the appointment happens at a consulate. The law gives no domestic route and no exception for people already living there.

For someone living in Britain that is simply convenient. For an American resident wanting to leave the system, it means travelling abroad to do it.

The consulate you use does not have to be in your country of residence, though in practice most people use the nearest one.

Do you need another nationality first?

Effectively yes. Renouncing without another citizenship leaves you stateless, and consular officers will spell out the consequences at length before they let you proceed. Most people in Britain already hold a British passport by this stage.

For someone who already holds a British passport this is a non-issue. For an American in Britain on a visa or with settled status, the British citizenship has to come first.

Naturalising as British takes its own time and has its own cost. Our guide to becoming British before renouncing covers how the two sequence.

What happens at the appointment?

A consular officer confirms you understand the consequences, you complete the paperwork and you take the oath of renunciation. It is deliberately formal because the act has to be voluntary and informed.

Some consulates require two appointments, one to explain and one to swear. Others handle it in a single visit depending on local practice.

You surrender your American passport at that point. Bring your British passport, because you will leave as a British citizen only.

What filings come afterwards?

A dual status return for the year of expatriation and Form 8854 alongside it. The return splits the year at the expatriation date and is more involved than an ordinary one.

Form 8854 is the piece that actually closes the tax relationship. Without it you remain a covered expatriate regardless of your numbers.

Our guide to US tax after renouncing covers what continues and what stops.

Is it cheaper to do nothing?

Over a long enough period, rarely. Annual compliance for an American in Britain costs more each year than people expect, and that cost repeats for life. The renunciation cost is a single payment against a recurring one.

Set the one-off renunciation cost against twenty or thirty years of annual preparation, PFIC reporting and foreign account filings. The arithmetic usually favours leaving, particularly for younger people.

In our practice the people who regret renouncing are those who did it for tax reasons alone and later wanted to work in America. The decision is permanent and that is the real consideration.

What should you budget for?

The consular fee, the catch-up work if you have filing gaps, the final dual status return, and any valuations the asset schedule needs. Those four components cover nearly every case we see.

Add contingency where you own a business, hold property in several countries or have interests in trusts. Those are the situations where the work expands.

Get a fixed quote for the catch-up before committing, because it is the component with the widest range and the one most likely to surprise you.

Can children renounce too?

They can, but the bar is high and gets higher the younger they are. A consular officer has to be satisfied the decision belongs to the child rather than the parent, which is difficult to establish below the mid teens.

A minor who renounces also keeps the right to reclaim citizenship within a window after turning eighteen. That makes the act less final for them than for an adult.

The fee applies to them in full regardless, which is part of why family renunciation cost adds up so quickly.

Does the fee ever change?

It has moved before and could again. The charge rose sharply in 2014 and has been the subject of litigation and proposals to reduce it since, without any change so far.

Plan on the current figure rather than waiting for a cut. People have been expecting one for several years.

The renunciation cost you budget for should be the published figure today.

Check the current amount before your appointment, because it falls due on the day and in the local equivalent.

What if you cannot afford the exit tax?

A deferral election exists for specific assets, letting you postpone the charge until you actually sell. It requires adequate security, usually a bond, and interest runs on the deferred amount throughout.

In practice the security requirement defeats most people. It is worth exploring where a single illiquid asset drives the charge and rarely worth it otherwise.

The alternative is restructuring before you go, which is why modelling the number early matters so much.

Does the timing within the year matter?

It does, in two ways. The exit tax uses asset values on the day before expatriation, so market levels on that single date drive the whole computation. The split of your final year shifts with it as well.

The split of your final year also shifts. Renouncing in January leaves almost the whole year outside the American system, while December leaves almost none of it.

Where income is uneven across the year, that split can matter more than the date itself.

What does the certificate look like?

A formal document confirming loss of nationality, issued after Washington approves the file. It carries the date of your oath rather than the date of issue, which is the date everything else keys off.

Banks and institutions ask for it for years afterwards, usually with no warning. It is the single document that proves you are no longer American.

Institutions rarely accept anything else as proof.

Scan it, store a copy separately from the original, and keep it permanently.

How to plan it

1. Confirm you hold or can obtain another nationality.
2. Establish which American tax years are outstanding.
3. Get a quote for bringing those filings up to date.
4. Complete the catch-up submission before anything else.
5. Value your worldwide assets against the $2 million threshold.
6. Model the exit tax if you are anywhere near it.
7. Book the consular appointment once compliance is in place.
8. File the dual status return and Form 8854 the following year.

Mistakes and penalties we see on renunciation cost

The first is budgeting for the fee alone. It is the smallest controllable number in the exercise for anyone with filing gaps.

The second is booking the appointment before finishing the catch-up. The certification then fails and a simple exit becomes a covered expatriation.

The third is forgetting that the fee is per person. A family of four pays nearly ten thousand dollars in consular fees alone.

The fourth is treating the final return as an afterthought. It falls due nearly a year later and people have often stopped thinking about any of it by then.

How US UK Tax Accountants helps

We tell you the full cost before you commit, not the fee in isolation. That means scoping the catch-up, modelling the exit tax where it might bite, and quoting the final year properly.

Then we do the work in the right order, so you satisfy the certification test before ever booking an appointment. Our expatriation service covers the whole sequence.
