Tax residence in the Czech Republic for Singapore taxpayers

The Czech Republic treats you as resident if you have a permanent home (bydliště) there, or if you stay at least 183 days in a calendar year — then from 1 January. It does not look at the centre of vital interests. Singapore decides your status for the calendar year with 183 days or more of presence or employment. If both countries claim you, Art. 4(2) of the Singapore–Czech Republic Agreement decides; salary follows a 183-day rule over any twelve-month period (Art. 15(2)).

When Czech Republic treats you as a tax resident

Czech law does not test the centre of vital interests: a permanent home in the Czech Republic (bydliště) or 183 days of presence is enough.

You have a permanent home in the Czech Republic (bydliště), so under Czech law you are a Czech tax resident from the day that home arose, wherever your family lives.
You spent 183 days or more in the Czech Republic in the calendar year — you are a Czech tax resident for the whole year, retroactively from 1 January.

When you are a non-resident

You are in the Czech Republic only to study or for medical treatment — under § 2(3) ZDP you are a non-resident even after 183 days.
No permanent home in the Czech Republic and fewer than 183 days — you are a Czech non-resident. Czech-source income (including pay for work physically done in the Czech Republic) is still taxed there.

Where the rules of the Czech Republic clash with Singapore tax rules

Collision: a Czech home is enough for Czech residence. Czech law does not look at the centre of vital interests: a permanent home in the Czech Republic makes you resident even if your family and economic life are in Singapore (NSS, 10 Afs 195/2017). If Singapore also treats you as resident, Art. 4(2) of the Singapore–Czech Republic Agreement decides: permanent home; with a home in both countries, centre of vital interests; if that cannot be determined, or you have a permanent home in neither, habitual abode; then nationality. If you are a national of neither country, the competent authorities decide by mutual agreement; the text does not deal expressly with a national of both. The steps are applied in sequence (NSS, 1 Afs 239/2017).
Collision: 183 days in the Czech Republic while resident in Singapore. After 183 days the Czech Republic treats you as resident for the whole calendar year from 1 January, while Singapore may treat you as resident for the same year on other grounds — as a citizen or Permanent Resident who normally lives in Singapore, or under IRAS's two- or three-year rules in the year you move. Under Art. 4(2) of the Agreement, if your only permanent home is in Singapore you are a resident of Singapore for treaty purposes. But under the GFŘ methodology even a rented flat in the Czech Republic can be a permanent home — then the centre of vital interests decides.

What else to know

Calendar year in both countries — but a rolling 12-month period for salary. Singapore and the Czech Republic both decide residence for the calendar year. Singapore: 183 days or more of presence or employment, normal residence as a citizen or Permanent Resident, or IRAS's two- and three-year rules. The Czech Republic: at least 183 days (every day begun counts), which make you resident retroactively from 1 January, or a permanent home (bydliště) from the day it arises. The 183-day test for salary in Art. 15(2)(a) of the Agreement counts the days you are employed in the Czech Republic in any twelve-month period — including days of arrival and departure, and weekends, holidays and related business trips after which the work resumed there (Art. 15(3)).
Working in the Czech Republic while resident in Singapore: 183 days in any 12 months (Art. 15(2)). Pay for work physically performed in the Czech Republic is Czech-source income even if the employer is from Singapore (§ 22(1)(b) ZDP). If Singapore is your treaty residence, the Czech Republic does not tax it only if all three conditions of Art. 15(2) are met: you are employed there for not more than 183 days in any twelve-month period (counted under Art. 15(3)), the pay comes from an employer who is not a Czech resident, and it is not borne by a permanent establishment or fixed base the employer has in the Czech Republic. Otherwise the Czech Republic taxes the pay for Czech work days. In Singapore such pay is foreign-sourced income, generally exempt for a resident individual (s. 13(7A)); where Singapore does tax it, the Czech tax is credited (Art. 22(1)).
How Singapore and the Czech Republic relieve double taxation. If Singapore is your state of residence, Czech income is generally not taxed in Singapore — foreign-sourced income received by a resident individual is exempt (s. 13(7A)); where Singapore does tax it, the Czech tax is credited against the Singapore tax on that income (Art. 22(1)) — claim the foreign tax credit in your Singapore return. Under para. 1 of the 1997 Protocol, a Czech exemption or reduced rate under the Agreement on income that Singapore taxes only when remitted applies only to the amount remitted to or received in Singapore. If the Czech Republic is your state of residence, it deducts the Singapore tax paid, up to the Czech tax attributable to the income Singapore may tax (Art. 22(2)(a); § 38f ZDP).
Year of moving: the Czech Republic splits the year under a treaty, Singapore does not. The Czech Republic recognises split-year residence under a treaty (dělená rezidence): for part of the year you may be a resident of Singapore for the Agreement, for part a Czech one. Singapore has no split year: your status is decided for the whole calendar year, although IRAS's two- and three-year rules can make a short first or last year a resident year. Match the periods so the same income is not taxed twice without relief.

How dual residence is resolved

If both countries treat you as a resident, Art. 4(2) of the treaty applies: Agreement between the Government of the Republic of Singapore and the Government of the Czech Republic for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income (signed at Singapore on 21 November 1997), with Protocol, as amended by the Protocol of 26 June 2013 and modified by the MLI. The tests are applied in order — permanent home, centre of vital interests, habitual abode, nationality, and finally mutual agreement between the tax authorities.

Questions

Does a flat in Prague make me Czech resident?

It can: a permanent home in the Czech Republic is enough under Czech law, whatever your days or centre of interests. If Singapore also treats you as resident, the Agreement decides — starting with where you have a permanent home.

How are the 183 days for salary counted?

Art. 15(2)(a) counts the days you are employed in the Czech Republic in any twelve-month period, including days of arrival and departure, and weekends, holidays and related business trips after which the work resumed there (Art. 15(3)).

What if habitual abode does not decide and I am a national of neither country?

Then the competent authorities of Singapore and the Czech Republic settle the question by mutual agreement (Art. 4(2)(d)). The text does not deal expressly with a national of both.

Case law

Nejvyšší správní soud (Supreme Administrative Court, Czech Republic), 10 Afs 195/2017-57, 16/07/2018 — The Income Taxes Act does not use the concept of a centre of vital interests: what matters for bydliště is a permanent home in the Czech Republic with the intention to live there permanently; family abroad is irrelevant under domestic law.
Nejvyšší správní soud (Supreme Administrative Court, Czech Republic), 7 Afs 251/2014-40, 22/01/2015 — Bydliště is not the same as a registered address or ownership of real estate — these are only indirect indications; a conclusion based on registration alone, without weighing work, studies and family abroad, cannot be reviewed.
