Everyone plans the arrival. Almost nobody plans the departure — and the departure is where the money is. Turkey's 20-year exemption has people pricing Istanbul from Barcelona, London, and a dozen American cities, and in every one of those conversations the hard questions are the same: when does your old country actually let go of you, what does it charge on the way out, and how do you time the landing so Turkey's clock starts when you want it to? I'm writing this as someone mid-corridor myself — a US citizen, Spanish tax resident, with the Turkish option on my own spreadsheet — so the Spain section below is the one I've lived against; the UK section is assembled from the statutory tests; the US section is the one that follows me personally wherever I go.
The universal sequence
Strip away jurisdiction detail and every clean move has the same skeleton: (1) end the old residency in a way you can prove, (2) start the new one at a date you chose deliberately, (3) file Turkey's exemption claim in that first year. The failure modes are equally universal: leaving "in your head" while the old country's tests still capture you; letting the two residencies overlap into a treaty fight you didn't plan for; and — new since July — becoming a Turkish tax resident and missing the İstisna Belgesi deadline at the end of that same calendar year. Hold that skeleton; here's the flesh, country by country.
Leaving Spain: all-or-nothing years and a paper trail Hacienda respects
The single most important fact about Spanish is that Spain has no split-year treatment: you are Spanish-resident for an entire calendar year or not at all. Trip any of the tests — 183+ days in Spain, your center of economic interests here, or the spouse-and-minor-children presumption — and January-to-December is Spain's, including whatever you earned after "moving" to Istanbul in May. The planning consequence is blunt: a Spain-to-Turkey move wants a year boundary. Leave early enough in the year that you stay under every Spanish test, or accept that the move effectively happens on January 1 of the following year — and note the happy symmetry that a genuine early-year arrival can make that same year your first Turkish residency year under the six-month test.
The exit paperwork is unglamorous and decisive. File Modelo 030 to notify Hacienda of your change of fiscal address; deregister from the padrón; keep evidence of the new life (Turkish lease or title, permit, utility contracts); and obtain a Turkish tax residency certificate for the first full year — the document Spanish tax offices actually ask for when they test a departure. Spain presumes continuity: without an affirmative record, you're resident until proven otherwise, and the burden runs the wrong way. Anyone leaving toward a low-tax destination should expect the file to be read skeptically and build it accordingly.
Two Spanish specifics deserve their own line. The exit tax (Article 95 bis): if you've been Spanish-resident for 10 of the last 15 years and hold shares worth over €4 million — or over €1 million in a single company where you own more than 25% — Spain taxes the unrealized gains at departure, at savings rates of 19–28%. Turkey is outside the EU/EEA, so the EU deferral mechanics don't help; below the thresholds, no exit tax applies, but the 10-of-15 clock is worth checking before your equity grows into the trap. And the Beckham cohort: if you're on the impatriate regime, its expiry is a natural exit ramp — the year your six-year window closes is the cleanest year boundary you'll ever get, which is exactly the calendar arithmetic we ran in the Beckham-vs-7582 comparison.
Leaving the UK: the SRT giveth, and the five-year rule waiteth
The UK is the mechanical one. The Statutory Residence Test decides residency by counting days against your "ties" (home, work, family, 90-day history), which means a UK exit can be engineered with a calendar and honesty about your visit patterns — a luxury Spain doesn't offer. Better still, the UK allows split-year treatment in qualifying cases: start full-time life abroad mid-year and the tax year divides, with the overseas part outside UK taxation. The planning is real but so is the discipline: your permitted UK day count after departure depends on your remaining ties, and the people who fail the SRT post-exit are almost always the ones who kept the London flat and the habits that go with it.
The trap with a delay on it is temporary non-residence: leave for five years or less, realize gains or take certain dividends while away, and the UK taxes them in the year you return as if you'd never left. A Turkey stint framed as "a few years of 0% then home" walks straight into it. If your plan involves crystallizing gains under Turkish residency, the five-year clock — and the fact that Turkey's exemption gives you no foreign tax credit to soften any UK charge — belongs in the model before you sell anything.
Leaving the US: you don't — you bring it with you
For US citizens there is no exit, only relocation: worldwide taxation, the 1040, , and all board the plane with you, and Turkey's exemption — as the pillar's US section lays out — mostly converts Turkish tax savings into US tax owed, since untaxed foreign income generates no . The genuinely actionable US-side work is different and twofold. First, the state layer: states like California, Virginia, South Carolina, and New Mexico are notoriously reluctant to release domiciliaries who keep ties — a driver's license, a spare bedroom, a registered vehicle can each anchor a state filing obligation from six thousand miles away. Sever deliberately (many movers re-domicile in a no-tax state first) and document it. Second, the clock: the foreign earned income exclusion runs on the physical-presence or bona-fide-residence tests, both of which reward a clean, documented departure date and punish the half-moved year. None of this is Turkey-specific — it's the standing tax hygiene of being an American abroad, applied to a new coordinate.
Landing in Turkey: the arrival is a tax event you schedule
Everything this site has published about the Turkish side compresses into four scheduling rules. Pick your first residency year on purpose — domicile-on-arrival claims the arrival year; the six-month presence test claims it only if you land early enough; the mapper does the arithmetic. Check the lookback before you commit — three clean calendar years with no Turkish domicile or disqualifying liability, where prior wage or business ties are fatal and passive investment history is protected. File the application in year one — form EK-1, due by the end of your first residency year (end of February following, for November–December arrivals), forfeited if late. And open the practical rails early — the bank account, the tax number, the lease in an open neighborhood — because every one of them is easier before you need it than after.
The overlap year — old country ending, Turkey beginning — is where treaties earn their keep. Spain and the UK both have modern treaties with Türkiye; if both countries claim the same year, the tiebreaker cascade (permanent home, center of vital interests, habitual abode, nationality) assigns it, and the documentation you kept decides how that conversation goes. The US treaty exists too, though for citizens the keeps the IRS in the picture regardless. Transition years are the one place in this whole process where I'd call professional help non-optional — the fee is noise against the cost of an overlap year argued badly. (When we've vetted exit advisors for these corridors, we'll say so here — and disclose the relationship.)
FAQ
Can I be tax resident in Spain and Turkey in the same year?
Easily — Spain's all-or-nothing year plus Turkey's six-month test makes overlap the default for mid-year moves. The Spain–Türkiye treaty tiebreaker then assigns the year based on facts you control: where the permanent home is, where life's center of gravity sits. Plan the move so the answer is obvious.
Does Spain's exit tax apply to me?
Only if you've been Spanish-resident 10 of the last 15 years and hold shares above €4 million total, or above €1 million with a stake over 25% in one company. Below those lines there's no charge — but the thresholds test your holdings at departure, so founders and equity-heavy professionals should check before the numbers grow.
I'm British — can I sell my portfolio tax-free from Turkey?
Turkey won't tax qualifying foreign gains under Law 7582 — but if you return to the UK within five years, the temporary non-residence rules tax those gains on re-entry, and Turkey's no-credit design means nothing offsets it. The plan only works if the departure is genuinely long.
As a US citizen, is there any point in the Turkish exemption?
Tax-wise it's muted — the US taxes your worldwide income regardless, and the exemption's savings largely become US tax owed. The case for Turkey is then lifestyle, cost base, and the state-tax and FEIE hygiene you'd want anywhere abroad. Go in with honest arithmetic, not the brochure's.
