Most families who come to Bali for a year think first about schools, a villa, and the rhythm of the days. The question of where they are taxed arrives later, usually as a quiet worry rather than a plan. It is worth meeting early. The mechanics are not frightening once they are laid out, but they are real, and they touch the year both at its start and at its end — including the part most people forget, which is going home.

What follows is the broad shape of it: how Indonesia comes to regard a long-staying visitor as a tax resident, what that changes, and how the country you have come from tends to treat your departure and your return. It is written to make you a better-informed client of a good accountant — not to replace one.

Read this first

This note is general guidance, not tax advice. It describes how these rules commonly work, not how they will work for you. Tax outcomes turn on the fine detail of your own circumstances — your nationality, where your income comes from, what you own, and the treaty between your country and Indonesia.

Before you act on anything here, confirm it with a qualified tax specialist in both Indonesia and your home country. We are glad to introduce you to advisers who do this work. For a family staying a year, Indonesian tax residency is not a risk to avoid; it is a fact to plan around.

The simple version: the 183-day line

Indonesia treats you as a tax resident once you are present in the country for more than 183 days within any twelve-month period — or earlier, if you arrive plainly intending to live here for a while. The 183 days need not be continuous; they are simply totted up across the rolling year from your arrival, and part-days, such as the day you land, generally count as whole days.

For a family taking a full year, this is not a borderline question. You will cross the line, comfortably, somewhere around the sixth month. The honest planning assumption for a twelve-month stay is that you will become an Indonesian tax resident during the year — so the sensible question is not whether, but what it means.

What changes when Indonesia counts you as resident

The defining change is reach. A non-resident is taxed by Indonesia only on income that arises in Indonesia. A resident is, in principle, taxed on worldwide income — salary, business profits, investment income and gains, wherever in the world they are earned or paid. That is the shift that matters, and it is why the year deserves a conversation with someone qualified before it begins.

Indonesian personal income tax is progressive. As at mid-2026 the rates for residents run in bands from 5 per cent on the first slice of annual taxable income up to 35 per cent at the top, stepping through 15, 25 and 30 per cent in between. A resident registers for a tax number — the NPWP — Nomor Pokok Wajib Pajak, the Indonesian taxpayer identification number — and files an annual return. These are indicative figures; rates and thresholds change, and your adviser will apply the current ones.

A genuine relief — but read the conditions

Indonesia offers certain newly-arrived foreigners a valuable concession: for up to the first four years of residency, they can be taxed only on Indonesian-source income rather than worldwide income.

It is not automatic and not universal. It is aimed at people with particular skills or expertise, comes with conditions, and is generally not available to those who instead rely on a tax treaty to protect the same income. Whether your circumstances fit is exactly the kind of question to put to an Indonesian tax specialist before you arrive — the answer changes the shape of your whole year.

The safety net: double-tax treaties

The prospect of two countries taxing the same income sounds alarming, and it would be, were it not for double-tax agreements. Indonesia has a wide network of them — with the United Kingdom, most of Western Europe, Australia, New Zealand, Canada, the United States and many more. Their job is to stop the same income being taxed twice, and to settle which country has the first or only claim.

Two ideas do most of the work. The first is the tie-breaker: when both countries could call you resident, the treaty decides which one wins, usually by looking at where your permanent home, your family and your closest ties sit. The second is the credit: where both may tax, the country with the secondary claim typically gives credit for the tax already paid to the other, so you pay the higher of the two rates rather than both in full. The detail varies treaty by treaty, which is precisely why this is specialist work.

Where you have come from

Becoming an Indonesian resident is only half the picture. The other half is how your home country treats the fact that you have gone. Some countries let you fall out of their tax net cleanly for a year; others hold on tight, and one holds on regardless of where on earth you live. What follows is a broad orientation — the headline of each story, not the fine print.

United States. Uniquely, the US taxes its citizens and green-card holders on worldwide income wherever they live. You keep filing every year. Relief comes through the Foreign Earned Income Exclusion (up to USD 132,900 of qualifying earned income per person for the 2026 tax year) and foreign tax credits — which usually reduce or remove the bill, but the filing obligation never goes away. Foreign-account reporting continues too.

United Kingdom. Residence is decided by the Statutory Residence Test. A clean year abroad can make you non-resident, often via ‘split-year treatment’ from your date of departure — but UK ties, and especially a home kept available to you, can keep you resident. A property left ready for your use is the classic trap.

Australia. Residency hinges on more than day-counting: the ‘domicile’ and ‘permanent place of abode’ tests look at whether you have genuinely set up life elsewhere. A single year, with a home and ties retained in Australia, often is not enough to cease residency — so worldwide income may remain taxable at home.

New Zealand. You stay tax-resident as long as you keep a ‘permanent place of abode’ — a home you retain a continuing connection to — regardless of days away. Ceasing residency generally needs both no such home and a long absence (over 325 days in twelve months). A one-year stay usually leaves NZ residency intact.

Canada. Residency turns on residential ties — home, family, belongings. Genuinely severing them can trigger a ‘departure tax’: a deemed sale of certain worldwide assets at market value on the day you leave, with tax on the paper gain, though the charge can often be deferred until you actually sell. For a temporary year, many keep ties and stay resident instead — a deliberate choice to make with an adviser.

Germany, France and the Netherlands. Each taxes residents on worldwide income and decides residency on where your life is centred — home, family, work — more than on a day-count. Leaving for a single year while keeping a home and family base often means you remain resident; the relevant treaty with Indonesia then prevents double taxation.

Switzerland. Residency follows your settled home and centre of vital interests. Cantonal rules and any lump-sum arrangements add their own wrinkles, so a Swiss-resident family should treat a year abroad as a question for their cantonal adviser rather than a settled answer.

“A single year abroad, with a home and family ties kept at home, frequently leaves your home-country residency in place — in which case the treaty, not a clean break, is what protects you from double tax.”

The United States is the exception that taxes you wherever you are. None of this is a reason to worry; it is a reason to map your own position before you fly.

While you are here

In practice, a well-advised family year tends to involve a short list of sensible steps rather than a heavy compliance burden. Knowing what is on the list is most of the comfort.

Register if required. If you become resident, you will likely need an Indonesian tax number and an annual return. Your visa and work status shape what is required; an Indonesian adviser will tell you what applies.

Keep clean records. A simple record of days in and out of Indonesia, and of where your income arises, makes every later question easier to answer — for both countries.

Mind the source of income. Whether you continue to earn from a home-country job, a business, or investments changes the picture considerably. This is the single most important thing to brief your adviser on.

Don’t drop the home-country thread. Most countries still expect a filing in your year of departure, and some throughout. Staying current at home is part of leaving well.

When the year ends and you go home

The return deserves as much thought as the departure, and usually gets less. Two things are worth holding in mind. The first is that your home country will, at some point in your journey back, begin to count you as resident again — and the timing of that, relative to when you stop being an Indonesian resident, decides where any income earned around the move is taxed. A clean handover beats an overlap.

The second is timing around income and assets. If you are due a bonus, a sale, a distribution, or any sizeable one-off, when it lands — while you are an Indonesian resident, in the gap, or after you are home again — can change which country taxes it and at what rate. These are answerable questions, but only in advance. Decided after the fact, they are simply outcomes.

The quiet ones to remember

Re-establishing home-country residency can itself have consequences — the unwinding of any departure-tax position, or the treatment of gains that accrued while you were away.

Foreign-account and asset reporting obligations often outlast the move in both directions; they tend to be about disclosure rather than extra tax, but missed deadlines carry their own penalties. Keep your records from the Bali year for several years after you return. The questions, if they come, come later.

What to take to your accountant

If this note does one useful thing, let it be this: it should let you walk into a first meeting already knowing the questions. A specialist can answer them quickly when they are framed well.

  • Will I become an Indonesian tax resident during the year, and from roughly when?
  • Does the four-year foreign-source concession apply to my situation, or am I better protected by the treaty?
  • Will I remain tax-resident in my home country for the year — and if so, how does the treaty divide things up?
  • What, if anything, do I need to register and file in Indonesia?
  • Is there a departure-tax or deemed-disposal issue when I leave home, or when I return?
  • How should I time any bonus, sale, or large one-off income around the move, in both directions?
  • What records should I keep, and for how long, on both sides?

A year in Bali is, in the end, a year of living somewhere fully — and being taxed somewhere is part of living somewhere fully. Met early and with the right adviser, it is a settled, unremarkable matter: a number of sensible steps, taken in order, that let the rest of the year be about the things you came for. It is one of the threads we help families pick up before they fly, alongside the family visa and the true cost of the year.

One last word. Everything above is general and may not fit your circumstances. It is not tax, legal or financial advice, and nothing here should be acted on without confirmation. Tax law changes, and the right answer for your family depends on details this note cannot see. Please verify all of it with a qualified tax specialist in both Indonesia and your home country before you make any decision. We are happy to introduce you to advisers we trust, and to help you prepare for that first conversation.
