Do You Still Owe State Taxes After Leaving the US for Costa Rica?

Do States Keep Taxing You After You Leave the Country?

The short answer for most states: no. When you establish domicile somewhere else, including in a foreign country like Costa Rica, most US states stop claiming taxing authority over you. Your federal tax obligations continue because the IRS taxes US citizens on worldwide income regardless of where they live. But states work differently.

States tax based on residency and domicile, not citizenship. Once you can demonstrate that you have severed your connection to a state and established a new permanent home, that state generally has no further claim to your income.

The problem is that "most states" is doing a lot of work in that sentence. Several states make it genuinely difficult to leave. And the difference between a clean break and a messy audit can come down to paperwork you filed, or forgot to file, before you left.

Which States Let Go Easily?

The majority of US states follow a straightforward rule: if you are no longer domiciled in the state and do not maintain a permanent place of abode there, you are not a resident for tax purposes. You may still owe tax on income sourced from within that state (rental income from a property you own there, for example), but your worldwide income is no longer their business.

States with no income tax make this even simpler. If your last US domicile was in Florida, Texas, Nevada, Wyoming, Washington, Alaska, South Dakota, Tennessee, or New Hampshire, there is no state income tax to sever in the first place.

For everyone else, the process involves filing a final part-year resident return in your departure year, then filing as a nonresident (or not at all) going forward, assuming you have no remaining source income in that state.

Which States Are "Sticky"?

Some states have earned a reputation for making it difficult to leave. They have aggressive tax authorities, broad definitions of residency, or specific statutory rules that keep former residents in the system longer than expected.

"California is the state that catches the most families off guard. People assume that once they're physically out of the country, California is done with them. The Franchise Tax Board does not see it that way. They will audit you years later if they think you left loose ends." Brennan Vitali, CFP, Vitality Wealth Planning

Here is a state-by-state breakdown of the most problematic states for people planning to split time between the US and Costa Rica:

State	Tax Authority	What Makes It Sticky	Key Rule
California	Franchise Tax Board (FTB)	Presumes you remain a resident until you prove otherwise. Broad definition of domicile. Active audit program targeting departing residents.	Safe harbor requires 546+ consecutive days outside CA under employment contract (CA Rev & Tax Code 17014). Without contract, domicile change requires accumulated evidence.
New York	NY Department of Taxation and Finance	183-day rule plus "permanent place of abode" test. Audits former residents aggressively.	If you maintain a home in NY and spend 184+ days there, you are a statutory resident regardless of where your domicile is (NY Tax Law 605(b)).
New Mexico	NM Taxation and Revenue Department	Treats anyone domiciled in NM as a resident for the entire year, even if they leave mid-year.	If you are domiciled in NM on January 1, you may owe tax for the full year. You must establish domicile elsewhere before year-end to break the cycle (NMSA 7-2-2).
South Carolina	SC Department of Revenue	Requires affirmative steps to abandon domicile. Default assumption is that you remain a resident.	SC uses an "intent to return" test. If you maintain property, keep voter registration, or retain a SC driver's license, the state considers you domiciled there (SC Code 12-6-30).
Virginia	VA Department of Taxation	Broad statutory residency. Domicile is "sticky" and can be difficult to change without clear documentation.	VA defines domicile as your "fixed, permanent and principal home" and requires clear evidence of abandonment plus establishment of new domicile (VA Code 58.1-302).
Connecticut	CT Department of Revenue Services	183-day rule with "permanent place of abode" threshold.	If you maintain a CT home and spend 184+ days in CT, you are a statutory resident. Also taxes income sourced from CT for nonresidents.
Minnesota	MN Department of Revenue	Presumes continuing residency unless you demonstrate a "permanent" move. 183-day rule applies.	MN considers 26 factors to determine domicile, including home ownership, voter registration, and where you receive mail (MN Statute 290.01).

What Does "Establishing Domicile in Costa Rica" Mean for State Tax Purposes?

Domicile is a legal concept, not just a physical location. It means the place you intend to make your permanent home, the place you intend to return to when you are away. For state tax purposes, changing your domicile requires two things: physically being in the new location and intending to stay there permanently.

For someone splitting time between the US and Costa Rica, establishing domicile in Costa Rica means demonstrating through objective evidence that Costa Rica is your primary home. States look at factors like:

• Where you maintain a home. If you keep a furnished house in your former state, that state has ammunition to argue you never left.
• Voter registration. Remaining registered to vote in a state signals intent to return.
• Driver's license. Keeping an active state driver's license is one of the easiest things auditors look for.
• Professional licenses. If you hold a license in a state and keep it active, that state may claim you.
• Where you receive mail. A mailing address in your former state can be used against you.
• Where your financial accounts are. Bank accounts and safe deposit boxes in the former state count.
• Where your family lives. If your spouse and children remain in the state, your domicile claim becomes much weaker.
• Community ties. Club memberships, religious organization membership, social organizations.

The strongest position is to cut as many of these ties as possible before leaving. Some families make the mistake of leaving quietly and assuming nobody will notice. Tax authorities notice.

What About the Pension Source Rule?

One of the most important federal protections for people leaving a state is 4 USC Section 114, sometimes called the "pension source rule." This federal law prohibits states from taxing retirement income of nonresidents.

This covers:

• 401(k) and 403(b) distributions
• IRA distributions (traditional and Roth)
• Pension payments from defined benefit plans
• Deferred compensation plans (457 plans)
• Military retirement pay

What it does NOT cover:

• Income from real property located in the state
• Business income sourced to the state
• Wages earned while physically working in the state

So if you leave California for Costa Rica and start taking 401(k) distributions, California cannot tax those distributions once you are no longer a California resident. This is federal law, and it overrides state tax codes.

The catch: you must actually be a nonresident. If California's FTB successfully argues that you never truly left, the pension source rule does not protect you because you are still classified as a resident.

How to Cleanly Sever State Tax Ties Before Leaving

The goal is to create a paper trail so clear that no state auditor can credibly argue you remained a resident. Here are the concrete steps:

Before you leave:

1. File a change of address with the US Postal Service. Forward mail to a family member or a mail forwarding service, not a PO Box in your old state.
2. Surrender your state driver's license. Get an international driving permit or a Costa Rican license once you are eligible.
3. Cancel voter registration in your former state. You can still vote in federal elections as a US citizen abroad using the Federal Post Card Application (FPCA).
4. Close or transfer bank accounts in your former state. Open accounts elsewhere or use a national bank without a state-specific presence.
5. Update your address with every financial institution, insurance company, and government agency.
6. Notify your state's tax authority if they have a formal departure process. California's FTB does not have a formal "departure form," but filing a final part-year return with clear documentation helps.

After you leave:

1. File a part-year resident return for your departure year. Report income only through your departure date as a resident.
2. Keep records of your travel, your Costa Rica lease or property documents, and your residency application timeline.
3. Avoid spending more than 183 days in your former state in any calendar year. Many states use day-count thresholds as a bright-line test.
4. Do not maintain a "permanent place of abode" in your former state. If you keep a home there, rent it out rather than keeping it available for personal use.

What If You Split Time Between the US and Costa Rica?

Many families who spend time in Costa Rica do not cut US ties completely. They keep a home in the US, spend winters in Costa Rica, and split the year between the two. This creates genuine complexity.

If you maintain a home in a sticky state and spend significant time there, you may remain a statutory resident regardless of where you claim domicile. New York's 183-day rule is the most well-known example: maintain a home in New York and spend 184 or more days there, and you are a New York resident for tax purposes, full stop.

The safest approach for someone splitting time is to establish US ties in a no-income-tax state (Florida is the most popular choice) and maintain Costa Rica as your primary international base. This eliminates state income tax exposure entirely while allowing flexibility in how you split your time.

What About State Taxes on Costa Rica-Sourced Income?

If you earn income in Costa Rica, your former state generally cannot tax it once you have established nonresidency. Costa Rica's territorial tax system means only Costa Rica-source income is taxed by Costa Rica. And once your US state no longer considers you a resident, they have no claim to your worldwide income either.

The exception is income sourced to the state itself. If you own rental property in California, California will tax that rental income regardless of where you live. If you run a business with operations in New York, New York will tax the portion of income attributable to New York. This is source-based taxation, and it follows the income, not the taxpayer.

The Bottom Line

Most states will let you go once you demonstrate a clean break. The states that cause problems are the ones with aggressive tax authorities and broad residency definitions, especially California, New York, and a handful of others.

The cost of getting this wrong is real. A California FTB audit on a departing resident can result in back taxes, penalties, and interest going back years. New York's audits are similarly thorough. And the burden of proof is on you to demonstrate that you left.

This is one of those areas where the planning you do before departure matters more than anything you can fix after the fact.
