Renouncing US citizenship? Get the tax right first: compliance, exit tax and Form 8854.
Before you renounce US citizenship, the IRS expects you to be up to date on the last five years of filing. Our US attorneys and IRS Enrolled Agents get you compliant first, calculate any exit tax, and file Form 8854, all in one firm.

Renounce US citizenship: the order of steps
Why tax compliance comes before you renounce US citizenship.
Many Americans, and many ‘Accidental’ Americans, who have lived outside the United States for years find it harder and harder to report worldwide income to the US. Some decide to renounce US citizenship.
When you renounce, the US may charge an expatriation tax, or “US exit tax”. One of the triggers is not having met your US tax obligations for the last five years. So if you are behind, you catch up first, then expatriate.
Form 8854 confirms that five-year compliance and lists your assets. It is filed with your US return for the year you expatriate.
Your net worth is over $2 million. Or your average US tax liability over the last five years is above $178,000 (adjusted for inflation). Or you cannot certify five years of US tax compliance. It can also apply to long-term green card holders: 8 of the last 15 years.
Before and after
Before and after you renounce US citizenship with the right tax help

Before: wanting out, but not sure of the tax
- Years abroad, still reporting worldwide income to the US
- Not sure if you are fully compliant for the last five years
- Worried the exit tax applies to you
- Do not know what Form 8854 needs

After: compliant, calculated, expatriated
- Five years of US filing brought up to date first
- Exit tax calculated, with planning where it helps
- Form 8854 prepared and filed on time
- A smooth exit, with US attorneys and EAs in one firm
Expatriation tax services
What we do when you renounce US citizenship.
Compliance first
If you are behind, we catch you up, for example through the streamlined procedures where eligible, before you expatriate.
Exit tax calculation
We work out whether the US exit tax applies and what it would be, based on a deemed sale of your assets.
Form 8854
The Expatriation Information Statement, prepared and filed with your final-year return. Failing to file it can mean a $10,000 penalty.
Planning above $2 million
If your net worth is over the $2 million trigger, there are planning opportunities that may help.
Green card holders
Long-term residents can face the exit tax too. A card left in a drawer still counts until it is formally given up.
Accidental Americans
Dual citizens from birth may be outside the $2 million trigger in some cases. We check whether that applies.

Questions
Renouncing US citizenship and tax: common questions.
Do I have to pay tax to renounce US citizenship?
Not always. The US exit tax applies if you meet one of the triggers: net worth over $2 million, average tax liability above $178,000 (adjusted for inflation), or not being compliant for the last five years.
What is Form 8854?
The Expatriation Information Statement. It establishes that you have expatriated, confirms five years of tax compliance and lists your assets. It is filed with your income tax return for the year you expatriate.
I am behind on US filing. Can I still renounce?
You can, but being non-compliant is one of the exit tax triggers. That is why we get you compliant first. See streamlined filing compliance procedures.
I am an ‘Accidental’ American. Does the exit tax apply?
If you were a dual citizen at birth, still hold the other citizenship and have had no substantial contacts with the US, the $2 million trigger may not apply. We check your facts.
I have a green card but left the US years ago. Am I affected?
Possibly. Green card holders for 8 of the last 15 years are long-term residents, and remain liable for US tax until the card is formally given up.
