Moving to the US From Cyprus: Your First US Tax Year

Relocating from Cyprus? The US decides tax residence by its own tests, your first year is usually split in two, and the US-Cyprus treaty settles dual residence. Here is how each piece works.

Quick answer

When does someone moving from Cyprus start paying US tax on worldwide income?

From the residency starting date: the first day in the US in a year you meet the substantial presence test, or the first day as a permanent resident under the green card test (IRS Pub 519). Before that you are a nonresident, so the first year is usually dual-status. If you are also resident in Cyprus, Article 3 (Fiscal Residence) of the treaty decides which country you are resident in for treaty purposes.

At a glance

When you become US resident: Green card test or substantial presence test (Code section 7701(b))
First year: Usually dual-status: nonresident, then resident
Treaty tie-breaker: Article 3 (Fiscal Residence)
Social security agreement: None on the SSA list
Accounts in Cyprus: FBAR, Form 8938 and PFIC rules can apply once resident

Your dual-status first year

Your first US year is usually split. Before your residency starting date you are a nonresident, taxed only on US income; from that date you are a resident, taxed on worldwide income, including anything earned in Cyprus after the date. This is a dual-status year (IRS Pub 519).

Under the substantial presence test, the starting date is generally your first day in the US that year; up to 10 days can be ignored if you kept a closer connection and tax home abroad.
Under the green card test, it is the first day you are in the US as a permanent resident.
If you arrive late in the year and miss both tests, the first-year choice can let you be treated as resident for part of it: 31 days in a row in the US and presence on 75% of the days from then to year end, and you must meet the substantial presence test the following year.

Arriving from Cyprus: which test applies

There is no form that makes you a US tax resident. It happens automatically under Code section 7701(b) once you pass either test (IRS Pub 519). A green card does it from the first day you are in the US with permanent resident status. Without one, the substantial presence test does it once you have 31 days this year and 183 weighted days over three years.

Someone arriving from Cyprus with no earlier US days needs to arrive by early July and stay for the rest of the year to pass the substantial presence test in the first year. The calculator shows the date for your arrival.

Resident in both countries: the US-Cyprus treaty tie-breaker

During the move you can be resident in both Cyprus and the US under each country's law. Article 3 (Fiscal Residence) of the treaty has the tie-breaker for someone resident in both countries: it looks first at where you have a permanent home available, then at the further tests the article lists, in the order it sets them. If the treaty makes you a resident of Cyprus, you can be taxed as a nonresident of the US for the treaty's purposes, but that position must be disclosed on Form 8833 under Treas. Reg. section 301.7701(b)-7 (IRS Form 8833).

Green card holders should be careful: a long-term resident who claims treaty residence abroad this way may be treated as having expatriated under section 877A (IRS).

Reporting what you keep abroad

Do not close everything in Cyprus in a hurry, and do not forget it either. As a US resident you report foreign accounts on the FBAR and Form 8938 when they pass the thresholds, and many investment funds bought in Cyprus fall under the PFIC rules (IRS). Details: FBAR and FATCA; Form 8938.

Common questions

When do I become a US tax resident after moving from Cyprus?

When you meet the green card test or the substantial presence test (31 days this year and 183 weighted days over three years). Your residency starting date is generally your first day in the US that year, or your first day as a permanent resident.

What if I am resident in both Cyprus and the US?

Article 3 (Fiscal Residence) of the treaty breaks the tie, starting with where you have a permanent home. Claiming treaty residence in Cyprus on a US return needs Form 8833.

Do I report my accounts in Cyprus after moving to the US?

Once you are a US resident, yes: the FBAR when foreign accounts total more than US$10,000, Form 8938 above higher thresholds, and PFIC rules for many foreign funds.

Is there a US social security agreement with Cyprus?

No, Cyprus is not on the SSA list of agreement countries.
