Do I have to file at home while living in Japan?
It depends on residence, not on address — except for US citizens and green-card holders, for whom the answer is yes regardless of where they live. We settle the residence question first, because every other answer follows from it.
Is there a treaty between my country and Japan?
Treaty networks change with each protocol and each multilateral-instrument position, so we confirm the treaty in force for your specific year with the issuing authority rather than relying on a published summary. Where there is none, unilateral relief and domestic law do the work instead.
I own property in Japan. Where is the rent taxed?
In Japan, because that is where the property sits. The complication is the base: gross-rent withholding takes no account of mortgage interest, tax or repairs, so a leveraged property can face tax on turnover. An election onto net profit, where it exists, is what fixes that — and it has its own timing.
When does Canada treat me as resident again after Japan?
On the date your ties resume, which is a question of fact rather than of paperwork. A lease or a purchase, a spouse and children arriving, a health card, a job that starts, and the day the shipping container is cleared all point at a date, and they do not always point at the same one. Pick the date the facts most clearly support, write down why, and then use it consistently on everything: the part-year return, the credit claim for the Japanese tax, and the valuation of what you owned when you arrived. The common error is choosing the flight date because it is easy to remember.
Do I have to file a final Japanese return before I leave?
Usually there is a closing obligation in Japan for the part of the year you were there, and it is much easier to deal with while you still hold a Japanese address, a Japanese bank account and a payroll contact who answers. Leaving it until after the move turns a routine filing into a correspondence exercise across two time zones. Ask your employer for the year-to-date payroll record before your last day, keep the residence certificate or its equivalent, and settle any balance before the account closes. We work backwards from the departure date when we plan the order of the filings.
I moved home in September — which country taxes my Japanese salary?
Split it by where the duties were performed and by the residence dates on each side. Salary earned for work done in Japan while you were resident there generally belongs to Japan; what you earn after the move belongs to the country you have come back to. The friction is in the overlap: a bonus paid after you left for work done before you left, unused leave paid out on termination, and a final payroll run that lands in the new month. Each is sourced by the period it was earned in, not by the date the money arrives.
Will my Japanese pension be taxed once I am back in Canada?
Once you are resident again, your worldwide income comes within the Canadian charge, and a pension paid from Japan is part of that. Japan may also tax it at source. The treaty in force for your year decides which side gives way and to what extent, and where both tax the same amount, the usual relief is a credit on the residence country's return rather than exemption at source. Two practical points: the payer needs your correct address and status on file, and the credit is claimed for the year the foreign tax relates to, not the year you happened to notice it.
What happens to my Japanese bank and brokerage accounts when I return?
They become foreign accounts the moment your residence changes, and that changes what you report at home rather than what you can hold. Residents are generally required to disclose foreign holdings above a reporting threshold each year, and income arising in those accounts is reportable whether or not it is brought across. Closing an account is not the only option and is often the wrong one, particularly where a Japanese pension or a lease deposit still has to be paid into it. What matters is that the accounts appear on the return from the first year of residence rather than being noticed in a later one.
I never filed at home while I was in Japan — what do I do now?
Bring the years up to date in order, oldest first, rather than filing the current year and hoping the rest goes unnoticed. Most systems have a route for voluntary correction, and it is materially better than being asked. The work is usually less than people fear: the Japanese payroll records and bank statements carry most of what is needed, and foreign tax already paid is generally creditable, so the balance owing is often smaller than the gross income suggests. Start by establishing which years you were actually resident, because that decides how many returns are in scope.
Does keeping a bank account or a house make me resident?
A house available to you is one of the strongest indicators, especially with family living in it. A bank account on its own is a secondary tie that matters only in aggregate. Authorities weigh the whole picture: dwelling, spouse and dependants first, then accounts, licences, memberships and registrations. Leaving with a suitcase while the family home stays occupied rarely ends residency. See keeping a home while abroad.
Can exit tax exposure be reduced before expatriating?
The levers are timing and facts, not a filing position. The certification test rewards having five clean years behind you, which takes planning rather than paperwork. Where assets are held, when gains are realised, and how deferred compensation and retirement interests are structured all change the outcome, and the effect of gifts before departure has to be weighed against the separate regime for gifts and bequests from covered expatriates. This is planning that needs a runway of years. See departure planning timelines.
