Costa Rica tax residency rules: who counts as resident in 2026

Last reviewed: November 2026 · Reviewed by Stéphane Gombauld, tax expert, technologist and digital nomad

You spend part of the year in Costa Rica and wonder whether that makes you a tax resident, and what follows if it does. This guide explains the legal test, how days are counted, what changes between resident and non-resident, and where treaties come in.

Costa Rica tax residency rules in 2026: the key figures

Is this guide for you?

Read on if you…

• split your year between Costa Rica and another country;
• earn some income from Costa Rica, such as rent, a local client or a local company;
• need to know which country can tax you, and on what.

Probably not your case if you…

• want a step-by-step move plan (see our practical guide to obtaining tax residency in Costa Rica);
• are looking for Panama's rules instead – start with tax residency in Panama.

Who is a tax resident in Costa Rica?

Article 2 of Ley 7092 lists who counts as a resident taxpayer. For individuals, two groups matter:

1. People physically present more than 183 days in the tax year, continuously or not. This is the rule for almost every expat.
2. Costa Rican nationals in the diplomatic or public service abroad, who stay resident while posted.

Companies and branches registered in Costa Rica are residents too. That matters if you run a Costa Rican entity – see legal forms of business in Costa Rica.

How the days are counted

The law speaks of a stay "of more than 183 days". There's no detailed counting rule for partial days in the law. The safe reading: any day you're physically in Costa Rica counts.

The count runs per calendar year. Since the 2019 reform (Ley 9635), the tax year runs 1 January to 31 December. Before, it ran October to September. Old guides still quote the old period.

What doesn't decide residency

• Your immigration status. A DIMEX residence card isn't proof of tax residency.
• Owning a home. Unlike Mexico or Spain, Costa Rica has no "home available" test in domestic law.
• Nationality. Costa Rican citizens abroad aren't resident unless they're on official duty.

What changes when you become resident?

Less than you'd think. Costa Rica uses a territorial principle: it taxes income generated in Costa Rica, by anyone. So residency mainly decides how local income is taxed, not whether foreign income is taxed.

Here's the catch for remote workers. Territorial means where the income is produced. If you work physically in Costa Rica, Hacienda may argue the income is Costa Rican-source, even if paid from abroad. The digital nomad law (Ley 10008) exempts qualifying remote workers, which removes that doubt for them.

What if two countries claim you?

This is where Costa Rica differs from most. It has few comprehensive tax treaties. Spain, Germany and Mexico are the main ones in force.

With a treaty

The treaty tie-breaker settles dual residency in a fixed order:

1. Permanent home – where you have a home available to you at all times.
2. Centre of vital interests – basically where your life is: family, main business, social ties.
3. Habitual abode – where you spend more time.
4. Nationality, then agreement between the two tax authorities.

Without a treaty

Both countries apply their own rules in full. Your home country may still tax your worldwide income. Costa Rica taxes only your local income. In practice, double tax hits only Costa Rican-source income, and only if your home country gives no credit.

Costa Rica signed the OECD multilateral convention on mutual assistance. It exchanges bank information with many countries under the CRS standard. Assume your home country will see Costa Rican accounts. More detail in our page on Costa Rica's international tax treaties.

How do you prove your status?

Proving you are resident

Hacienda can issue a certificado de residencia fiscal – a tax residency certificate – to registered taxpayers. You'll need it to claim treaty benefits abroad. Request it through Hacienda's online platform.

Proving you are not resident

Keep entry and exit stamps, flight tickets and your lease abroad. If you stay at or under 183 days, these records are your defence. The burden of proof is on you.

Common mistakes (and what they cost)

• Using the old October–September tax year → you miscount your 183 days and file for the wrong period.
• Treating your DIMEX as tax residency → you claim resident status (or deny it) on the wrong basis and lose treaty relief.
• Assuming territorial means remote work is tax-free → possible reassessment of local-source income, with interest and penalties.
• Ignoring your home country's rules → with no treaty, your old country may keep taxing your worldwide income in full.
• Not keeping travel records → you can't rebut a residency claim when either authority asks.

Frequently asked questions

What is the 183-day rule in Costa Rica?

You're a Costa Rican tax resident if you're physically present more than 183 days in the calendar year, under article 2 of Ley 7092. Days are added up across the year, so they don't need to be consecutive. At 183 days or fewer, you're a non-resident and only your Costa Rican-source income is taxed, through withholding.

Does being a Costa Rican tax resident mean I pay tax on worldwide income?

No. Costa Rica is territorial: residents and non-residents are taxed only on income produced in Costa Rica. Foreign investment income stays outside the net. The open question is work physically done in Costa Rica for foreign clients, which Hacienda may treat as local-source unless you hold the digital nomad status.

Can I be a tax resident of Costa Rica and another country at the same time?

Yes. Each country applies its own rules. If there's a treaty, such as with Spain, Germany or Mexico, the tie-breaker decides using permanent home, vital interests, habitual abode and nationality. Without a treaty, both apply in full, though Costa Rica only ever taxes your local income.

Does owning property in Costa Rica make me a tax resident?

No. Costa Rican law has no home-ownership test. Only the 183-day physical presence count matters for individuals. But the property's rental income and any gain on sale are Costa Rican-source and taxed, whether you're resident or not. Rental income is taxed at 15% on 85% of gross rent.

How do I get a Costa Rican tax residency certificate?

You request a tax residency certificate from the Ministerio de Hacienda through its online platform. You normally need to be registered as a taxpayer and meet the 183-day test. The certificate is what a foreign tax authority or payer asks for before granting treaty benefits, such as reduced withholding.
