Quick answer

When does someone moving from Ukraine 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 Ukraine, Article 4 (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 4 (Residence)
Social security agreement: None on the SSA list
Accounts in Ukraine: FBAR, Form 8938 and PFIC rules can apply once resident

The two US residency tests

Test	You are a US tax resident if	Source
Green card	You hold lawful permanent resident status at any time during the calendar year	Pub 519
Substantial presence	31 days this year and 183 weighted days over 3 years (all of this year, one third of last year, one sixth of the year before)	Pub 519

These come from Code section 7701(b). A work visa, a student visa or a move for family from Ukraine all go through the same two tests; some visa holders can exclude days. Try the calculator.

The treaty tie-breaker

Article 4 (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.

Point	What it means
Who uses it	People resident in both Ukraine and the US under each country's own rules, typically in the year of the move
How it is claimed	Form 8833 with the US return, under Treas. Reg. section 301.7701(b)-7 (IRS)
Risk for green card holders	Long-term residents may be treated as expatriated under section 877A

The first US return after Ukraine

The first US return after leaving Ukraine is rarely a normal one.

Situation	What applies
Arrived mid-year and passed a test	Dual-status year: nonresident before the residency starting date, resident after it
Arrived late and passed neither test	Nonresident for the year, unless the first-year choice applies (31 consecutive days and 75% presence, plus the substantial presence test next year)
Married to someone still in Ukraine	Special rules let some couples choose to file as residents for the whole year

Accounts left in Ukraine

Keeping a Ukrainian bank account or pension after the move is normal, but from your residency starting date the US wants to know about it. The reports are the FBAR, Form 8938 and, for many non-US funds, the PFIC rules on Form 8621 (IRS). Thresholds and deadlines: FBAR and FATCA, Form 8938.

Where these rules come from

The IRS lists the 1994 income tax treaty. General effective date (IRS Table 3): treaty Jan. 1, 2001 (IRS treaty documents for Ukraine; treaty text; IRS Table 3).
Residence and tie-breaker: Article 4 (Residence).
Saving clause: paragraph 3 of Article 1 (General Scope).
Article 19 (Pensions), pensions.
Article 24 (Relief from Double Taxation), relief from double taxation.
Article 15 (Dependent Personal Services), employment income.

US law

US residency tests and starting dates: Code section 7701(b) (IRS Pub 519).
Treaty residence for dual residents: Treas. Reg. section 301.7701(b)-7, Form 8833 and section 6114; long-term residents: section 877A (IRS Form 8833).

The rules of Ukraine on leaving the country also apply; check them with a local adviser.

Common questions

Am I a US tax resident in my first year after leaving Ukraine?

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 Ukraine and the US?

Article 4 (Residence) of the treaty breaks the tie, starting with where you have a permanent home. Claiming treaty residence in Ukraine on a US return needs Form 8833.

Do I report my accounts in Ukraine 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 Ukraine?

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