Does Costa Rica Tax US Retirement Account Withdrawals?
No. This is the single most important thing to understand, and it comes down to one concept: territorial taxation.
Costa Rica taxes only income that originates within Costa Rica. Your 401(k), traditional IRA, Roth IRA, pension, and Social Security are all US-sourced income. Costa Rica has no claim to any of it. This applies whether you hold temporary residency, permanent residency, or are spending time in the country on a tourist visa.
There is no US-Costa Rica tax treaty. But you do not need one here because Costa Rica's domestic tax code, which taxes only territorial income, already excludes your US retirement distributions from Costa Rican taxation.
The US side is where the tax picture gets more interesting.
How Are Traditional 401(k) and IRA Distributions Taxed?
Distributions from traditional 401(k) plans and traditional IRAs are taxed by the United States at ordinary income tax rates, regardless of where you live. The tax treatment does not change because you split time with Costa Rica.
For 2026, the federal income tax brackets for a single filer are:
| Taxable Income | Tax Rate |
|---|---|
| Up to $11,925 | 10% |
| $11,926 to $48,475 | 12% |
| $48,476 to $103,350 | 22% |
| $103,351 to $197,300 | 24% |
| $197,301 to $250,525 | 32% |
| $250,526 to $626,350 | 35% |
| Over $626,350 | 37% |
(Source: IRS Revenue Procedure 2025-11)
If your traditional 401(k) distribution is $80,000 and that is your only income, you are paying a blended effective rate across those brackets. You will owe federal taxes on every dollar. Costa Rica adds nothing on top.
The mistake people make is assuming that splitting time abroad somehow reduces or eliminates the US tax obligation on these distributions. It does not.
What About Roth IRAs?
This is where the math gets genuinely compelling for families planning a cross-border life.
Qualified Roth IRA distributions are tax-free in the United States. A "qualified distribution" means you are at least 59 1/2 and the account has been open for at least five years (IRS Publication 590-B).
Costa Rica does not tax them either, because they are US-sourced.
That means qualified Roth IRA distributions are taxed by nobody. Zero percent. Both countries.
For families building toward a life that splits time between the US and Costa Rica, the Roth IRA is the most powerful retirement vehicle available. Every dollar in a Roth is a dollar you keep, in full, on both sides of the border.
How Do Traditional and Roth Accounts Compare for Cross-Border Families?
| Factor | Traditional IRA / 401(k) | Roth IRA | Roth 401(k) |
|---|---|---|---|
| US tax on contributions | Tax-deductible | After-tax (no deduction) | After-tax (no deduction) |
| US tax on qualified distributions | Ordinary income rates (10-37%) | Tax-free | Tax-free |
| Costa Rica tax on distributions | None (US-sourced) | None (US-sourced) | None (US-sourced) |
| RMDs required? | Yes, starting at age 73 | No (during owner's lifetime) | Yes, but can roll to Roth IRA to avoid |
| FEIE applies? | No | No | No |
| Best for cross-border? | Adequate | Optimal | Strong (roll to Roth IRA) |
The difference is stark. Traditional accounts generate taxable income every year you take distributions. Roth accounts generate none. When you are already paying for two households, managing currency exchange, and covering international insurance, eliminating an entire tax liability is a significant financial advantage.
Do Required Minimum Distributions Still Apply?
Yes. If you hold traditional 401(k) or traditional IRA accounts, you must begin taking Required Minimum Distributions at age 73 under the SECURE 2.0 Act (IRS guidance on RMDs). This applies regardless of where you live.
RMDs are calculated based on your account balance at the end of the prior year divided by a life expectancy factor from the IRS Uniform Lifetime Table. You cannot skip them. Failure to take a required distribution results in a 25% excise tax on the amount not withdrawn (reduced from 50% under SECURE 2.0, and further reduced to 10% if corrected within two years).
RMDs are taxed as ordinary income by the US. Costa Rica does not tax them.
Roth IRAs have no RMDs during the owner's lifetime. This is another reason the Roth is the preferred vehicle for cross-border retirement. You control the timing and amount of withdrawals entirely.
The Roth Conversion Ladder: The Pre-Departure Tax Strategy
"The Roth conversion window before departure is the single most valuable tax move families can make. You have a finite number of years where your income is lower, your bracket is favorable, and you can systematically convert traditional retirement money into tax-free Roth money. Once that window closes, you are stuck with the tax profile you built." Brennan Vitali, CFP, Vitality Wealth Planning
Here is how it works.
A Roth conversion takes money from a traditional IRA or 401(k) and moves it into a Roth IRA. You pay income tax on the converted amount in the year of conversion. After that, the money grows tax-free and comes out tax-free in qualified distributions.
The strategy is to do this in stages over 3-5 years before you begin splitting time with Costa Rica, while your income may be lower during the transition period. If you have left a W-2 job, taken a sabbatical, or are in a gap year before your next chapter, your taxable income drops and you can convert at the 12% or 22% bracket instead of the 32% or 35% bracket you were in while working.
The 5-year rule matters. Each Roth conversion has its own 5-year clock. If you withdraw converted funds before five years, the earnings portion may be subject to tax and a 10% penalty if you are under 59 1/2 (IRS Publication 590-B). Planning your conversion timeline 5+ years before you need the money is critical.
A Practical Example
A couple in their mid-50s plans to begin splitting time with Costa Rica in 5 years. They have $800,000 in traditional IRAs and $200,000 in Roth IRAs.
- Year 1-5: They convert $100,000-$150,000 per year from traditional to Roth, paying tax at the 22-24% bracket
- Year 6+: They begin withdrawing from Roth accounts tax-free in both countries
- Result: Instead of paying 32-35% on forced RMDs in their 70s, they paid 22-24% voluntarily in their 50s and converted $500,000-$750,000 to permanently tax-free status
The math is straightforward. The discipline to execute it is the hard part.
Does the Foreign Earned Income Exclusion Help with Retirement Income?
No. The Foreign Earned Income Exclusion (FEIE) under IRC Section 911 applies only to earned income, which the IRS defines as wages, salaries, and self-employment income.
Retirement distributions are not earned income. They are deferred compensation or investment returns. The FEIE does not apply to:
- 401(k) distributions
- IRA distributions (traditional or Roth)
- Pension income
- Social Security benefits
- Investment income (dividends, interest, capital gains)
- Annuity payments
If your retirement income is your primary income source, the FEIE provides zero benefit. This is a common misconception among people planning a move abroad. The exclusion is relevant for remote workers and business owners with earned income, not for retirees living on distributions.
How Is Pension Income Taxed?
Pension income from a former US employer follows the same rules as traditional 401(k) and IRA distributions. It is taxed by the US at ordinary income tax rates. Costa Rica does not tax it because it is US-sourced income.
There is no special treatment for pensions. Whether your pension comes from a private employer, a state government, or the federal government, the US tax treatment is the same. If there were a US-Costa Rica tax treaty, pension income might receive specific treaty provisions. There is no such treaty, but again, Costa Rica's territorial system means this gap does not create double taxation.
If you receive a pension from a Costa Rican employer, that would be Costa Rica-sourced income and subject to Costa Rican tax. For most families reading this, that scenario does not apply.
What Should You Do Before You Leave?
The planning window matters more than most people realize. Here is what the timeline looks like:
5+ years before departure:
- Begin Roth conversions at favorable tax brackets
- Model your projected retirement income to determine optimal conversion amounts
- Confirm your investment accounts will work with a foreign address
2-3 years before departure:
- Accelerate conversions if bracket space allows
- Review your overall tax picture including state tax obligations
- Ensure each conversion batch has started its 5-year clock
1 year before departure:
- Final conversion batch
- Confirm RMD strategy for any remaining traditional accounts
- Engage a cross-border tax professional who understands both US tax code and Costa Rica's territorial system
After departure:
- Continue taking RMDs from any remaining traditional accounts (US-taxed, CR-exempt)
- Draw from Roth accounts tax-free in both countries
- File US taxes annually, the obligation does not end
- Understand your full retirement comparison picture
The Bottom Line
Your US retirement accounts are not taxed by Costa Rica. That is the good news, and it is significant. But they are still taxed by the United States, and the type of account determines how much you pay.
Traditional 401(k)s and IRAs create a mandatory, taxable income stream through RMDs. Roth IRAs create a flexible, tax-free income stream with no RMDs. The difference compounds over decades, and for families splitting time between two countries, the Roth advantage is even more pronounced because neither country taxes the distributions.
The Roth conversion ladder before departure is the highest-impact planning move available. It is not complicated. It just requires time, discipline, and a plan that starts years before you board the plane.
If your retirement accounts are sitting in traditional vehicles and you are thinking about a cross-border life, the clock on your conversion window is already ticking.
