If you own a rental property in Japan, the tax you owe is not based on the total rent you collect. It is based on fudōsan shotoku (不動産所得, "real estate income"): your annual rental income minus your allowable expenses. This distinction surprises many international owners who assume Japan taxes gross rent the way some jurisdictions do. For salaried employees who also earn rental income, a kakutei shinkoku (確定申告, annual final tax return) becomes mandatory once this real estate income exceeds 200,000 yen (approx. USD 1,300 as of 2026-08) in a calendar year. This guide walks through every tax that applies to Japanese rental income, how to calculate income tax and resident tax, which expenses are deductible and which are not, the filing process and required documents, and the penalties for not filing — everything an owner, whether based in Japan or investing from abroad, needs to plan a full tax year.
Key Takeaways
- What is taxed is not your gross rent, but fudōsan shotoku (不動産所得) — rental income minus deductible expenses.
- Salaried employees must file a kakutei shinkoku (確定申告) once real estate income exceeds 200,000 yen (approx. USD 1,300) a year; even below that line, a separate resident tax filing is still required.
- National income tax uses a chōka ruishin zeiritsu (超過累進税率, progressive bracket system) that rises with taxable income, while resident tax (住民税, jūminzei) runs at roughly a flat 10%.
- Choosing aoiro shinkoku (青色申告, the "blue return" system) unlocks a special deduction of up to 650,000 yen (approx. USD 4,200) and a three-year carryforward of losses; the full benefit requires owning at least 5 buildings or 10 units — a scale threshold known informally as the gotō jisshitsu kijun (5棟10室基準).
- Failing to file triggers a mushinkoku kasanzei (無申告加算税, late-filing penalty) of 15–20%, and if the tax office judges the omission intentional, a jūkasanzei (重加算税, heavy additional tax) of 35–40% applies instead.
What Taxes Apply to Rental Income in Japan?
Owning an apartment (アパート) or condominium unit (マンション) that generates rent in Japan triggers more than just income tax. This is a distinctly Japan-specific tax stack compared to many single-tax-on-rent jurisdictions: five separate taxes can apply to a single rental property, each with its own timing. Unlike countries where rental tax obligations are consolidated into one annual bill, Japan separates national income tax, resident tax, consumption tax, fixed asset tax, and a one-time acquisition tax, each administered by a different authority. Understanding all five — not just income tax — is what lets an owner forecast annual cash flow accurately.
| Tax | What triggers it, and when | Key point |
|---|---|---|
| Income tax (所得税, shotokuzei) | Levied annually on real estate income | At the scale of 5 buildings or 10 units (5棟10室基準), income is reclassified as jigyō shotoku (事業所得, business income), which widens the range of deductible expenses and available deductions |
| Resident tax (住民税, jūminzei) | Levied annually, based on the prior year's income | Income tax has a 200,000 yen (approx. USD 1,300) exemption threshold, but resident tax does not — it applies regardless of amount |
| Consumption tax (消費税, shōhizei) | Applies once taxable sales reach 10,000,000 yen (approx. USD 64,500) or more | Residential leasing alone is tax-exempt; check that the lease explicitly states "residential use" (住宅用) |
| Fixed asset tax and city planning tax (固定資産税・都市計画税) | Billed every year simply for owning the property | Properties inside an urbanization promotion area (市街化区域) also owe city planning tax |
| Real estate acquisition tax (不動産取得税, fudōsan shutokuzei) | One-time, at the time of purchase | The bill typically arrives six months to a year and a half after acquisition — budget for it as a delayed, one-time cash outflow |
Of these five, fixed asset tax is the fixed cost with the most direct, year-after-year effect on what you actually keep. For a full breakdown of how it's calculated and when the bills arrive, see our guide: How Japanese Fixed Asset Tax Is Calculated, and When You Pay It.
Keeping Rental Income Private From Your Employer: Resident Tax Options
This is the single most common question we hear from salaried clients: will my employer find out about my rental income? In Japan, resident tax on side income is normally collected the same way as tax on your salary — deducted directly from your paycheck (特別徴収, tokubetsu chōshū, "special collection") — which can reveal a jump in your resident tax bill to HR. The fix is simple: on the tax return, you can elect futsū chōshū (普通徴収, "ordinary collection") for the resident tax owed on rental income, which sends you a separate payment slip instead of routing it through payroll. This is a checkbox on the return itself, not a separate application, so anyone concerned about their employer noticing should confirm this election at filing time.
What Is Real Estate Income (Fudōsan Shotoku)? How It Differs From Rental Income
Fudōsan shotoku (不動産所得, "real estate income") is your annual rental income minus your annual deductible expenses — it is not the rental income itself. This is the single most important distinction for an international owner to internalize, because it means two owners collecting identical rent can owe very different amounts of tax depending on how carefully they track expenses.
Real Estate Income = Annual Rental Income − Annual Deductible Expenses
The accounting period runs from January 1 to December 31 — Japan's tax year matches the calendar year, unlike jurisdictions that use a fiscal year offset from January. Tax owed is determined the following year, when the return for that calendar year is filed. Two owners with identical gross rent can end up keeping very different net amounts, purely based on how precisely they track expenses.
What Counts as Rental Income
"Rental income" is broader than the monthly rent check. The following must also be tallied as income for tax purposes:
- Reikin (礼金, non-refundable "key money" paid by the tenant), management fees, and lease renewal fees (更新料, kōshinryō)
- Parking space income
- Fees for hosting a mobile-carrier antenna installation on the building
- Income from vending machines on the property
- Electricity and water charges collected from tenants as shared-facility fees (共益費, kyōekihi)
The items most often missed are vending machine income and antenna fees, because they frequently land in a different bank account from the rent itself. The safest way to avoid an omission is to reconcile every account that receives money — not just the account tied to a specific property — against the full year's deposits.
How Unpaid (Delinquent) Rent Is Treated
Japan's rule here differs from a simple cash-basis approach: even if a tenant falls behind on rent, the amount they owed is still recorded as income for the year it was due, not excluded just because it was never actually received. Only once the debt is formally confirmed as uncollectible can it be booked as a loss. This means the paperwork trail matters — keep a clear record of when the arrears occurred and when they were confirmed uncollectible, so the filing treatment is defensible.
Which Expenses Are Deductible, and Which Are Not?
Claiming expenses directly reduces taxable income, which makes it the foundation of legitimate tax planning for a Japanese rental property. But not everything qualifies, and drawing the line incorrectly is one of the most common triggers for a tax office inquiry.
Deductible Expenses
| Expense category | Details |
|---|---|
| Taxes | Fixed asset tax, city planning tax, real estate acquisition tax, and stamp duty on documents (income tax and resident tax themselves are not deductible) |
| Insurance premiums | Fire insurance, earthquake insurance, and other property-related policies |
| Outsourcing / management fees | Fees paid to a property management company (typically around 5% of rent) |
| Professional fees | Fees paid to a licensed tax accountant (税理士, zeirishi) or judicial scrivener (司法書士, shihō shoshi) |
| Depreciation (減価償却費, genka shōkyaku-hi) | Spread over the building's statutory useful life: 22 years for wood-frame construction, 34 years for steel-frame, 47 years for reinforced concrete (RC) |
| Repair costs | Wallpaper replacement, equipment repair, cleaning fees, contributions to a repair reserve fund, and restoration costs at move-out (原状回復費用, genjō kaifuku hiyō) |
| Advertising | Costs of recruiting new tenants |
| Loan interest | Interest on borrowed funds and loan arrangement fees |
| Other | Transportation costs for property inspections and management, and real-estate reference books |
Non-Deductible Expenses
- The principal-repayment portion of a loan (only the interest portion is deductible)
- Income tax and resident tax themselves
- Personal living expenses for the portion of a building you occupy yourself
- Costs of obtaining a qualification or license unrelated to acquiring the real estate
The most common error by far involves loan repayment. Treating the entire monthly repayment as a deductible expense understates real estate income — a mistake that compounds every year of the loan. Request the amortization schedule from your lender and separate principal from interest before tallying expenses.
How Is Tax on Rental Income Calculated?
Calculating National Income Tax
National income tax is calculated in three steps:
- Real estate income = Rental income − Deductible expenses
- Taxable income = Real estate income + Other income − Applicable deductions
- Income tax = Taxable income × Tax rate − Deduction amount
The tax rate follows a chōka ruishin zeiritsu (超過累進税率, "excess progressive rate") that climbs in steps as taxable income rises — conceptually similar to progressive brackets used in many countries, though Japan's specific thresholds and rates are its own. The main brackets are:
| Taxable income | Rate |
|---|---|
| Up to 1,950,000 yen (approx. USD 12,600) | 5% |
| Up to 3,300,000 yen (approx. USD 21,300) | 10% |
| Up to 6,950,000 yen (approx. USD 44,800) | 20% |
| Above 40,000,000 yen (approx. USD 258,000) | 45% |
The brackets between these thresholds, and the deduction amount that applies at each level, are published by the National Tax Agency (国税庁, Kokuzeichō) in its official quick-reference income tax table. Major categories of deduction include the basic deduction, social insurance premium deduction, medical expense deduction, spousal deduction, dependent deduction, and — specific to rental property owners who file under the blue-return system — the aoiro shinkoku special deduction (青色申告特別控除) of up to 650,000 yen (approx. USD 4,200). Because these deduction amounts change with tax reform, always confirm the current-year figures on the Kokuzeichō website before calculating.
Calculating Resident Tax
Resident tax (住民税, jūminzei) is a simpler calculation: a rough flat rate of about 10% of income. An income of 6,000,000 yen (approx. USD 38,700) works out to roughly 600,000 yen (approx. USD 3,870) in resident tax. The practical difference from national income tax is that resident tax has no 200,000-yen exemption — it applies even when real estate income is 200,000 yen (approx. USD 1,300) or less.
For the bigger picture of how much rental income you actually keep after every tax and expense, see: How Japanese Real Estate Investment Works: Understanding Rental Income.
When Is a Kakutei Shinkoku (Tax Return) Required?
The threshold is measured against income, not revenue. If annual rental income is 1,000,000 yen (approx. USD 6,450) but deductible expenses total 850,000 yen (approx. USD 5,480), real estate income is only 150,000 yen (approx. USD 970) — and a salaried employee at that level does not need to file an income tax return at all.
When Filing Is Required
- Salaried employees whose real estate income exceeds 200,000 yen (approx. USD 1,300) a year
- Sole proprietors and freelancers who have any real estate income at all
- Anyone earning rental income from multiple properties
When Filing Isn't Required — and Why You May Still Want To
- Salaried employees whose real estate income is 200,000 yen (approx. USD 1,300) or less a year (a separate resident tax filing is still required)
- Cases where deductible expenses exceed rental income, producing a loss
A loss year is exactly when filing is most valuable, not least. Japan allows son'eki tsūsan (損益通算, "profit-and-loss offsetting"), which lets a real estate loss offset salary income directly — refunding tax you already overpaid through payroll withholding. This matters most in the year of a major renovation, or a year when several tenant turnovers stack up genjō kaifuku (原状回復, restoration-to-original-condition) costs at once. Filers using aoiro shinkoku (青色申告) get an additional benefit: any loss that isn't fully absorbed by that year's salary income can be carried forward for three years.
Aoiro Shinkoku vs. Shiro Shinkoku: Which Filing System Is Better?
Between Japan's two individual tax-filing systems, aoiro shinkoku (青色申告, literally "blue filing," Japan's elective bookkeeping-based return) is the clearly stronger option, thanks to its special deduction and loss carryforward. Its one cost is that it requires double-entry bookkeeping (複式簿記, fukushiki boki) rather than the simpler records shiro shinkoku (白色申告, "white filing," the default system) allows — but modern accounting software has largely closed that gap in practical effort.
| Item | Aoiro Shinkoku (Blue) | Shiro Shinkoku (White) |
|---|---|---|
| Special deduction | Up to 650,000 yen (approx. USD 4,200) | None |
| Bookkeeping method | Double-entry bookkeeping | Simplified records are sufficient |
| Loss carryforward | Up to 3 years | Not available |
| Advance registration | Required (business commencement notice + blue-return approval application) | Not required |
Reaching the full 650,000-yen (approx. USD 4,200) deduction requires operating at the gotō jisshitsu kijun (5棟10室基準) scale — at least 5 buildings, or 10 individual units. Below that threshold, a smaller deduction of 100,000 yen (approx. USD 650) is still available, which means even an owner starting with a single condominium unit has a reason to choose aoiro shinkoku over the default system.
The Kakutei Shinkoku Process and Required Documents
The kakutei shinkoku filing window runs every year from February 16 to March 15, covering the previous calendar year's income. The process follows five steps:
- Tally annual rental income: sum monthly rent, reikin key money, renewal fees, parking income, and all other items covered above.
- Tally annual deductible expenses: work from receipts and statements to capture every qualifying expenditure without omission.
- Calculate real estate income: subtract deductible expenses from rental income.
- Prepare the settlement statement and the return: shiro shinkoku filers complete an income-and-expense statement (収支内訳書); aoiro shinkoku filers complete a blue-return settlement statement (青色申告決算書); both figures then transfer onto the tax return itself. The Kokuzeichō's online preparation portal walks through each field.
- Submit the documents: choose between e-Tax (Japan's electronic filing system), postal mail, or delivering the return in person to the tax office. e-Tax accepts submissions 24 hours a day and removes the need to visit a tax office at all — a practical advantage for owners filing from overseas.
Choosing aoiro shinkoku requires a step before any of the above: the blue-return approval application (青色申告承認申請書) must be filed within two months of starting the rental business. Miss that window, and the filing defaults to shiro shinkoku for that tax year regardless of intent — there is no retroactive election.
Required Documents and Where to Obtain Them
To avoid a last-minute scramble, it helps to know in advance where each document comes from:
| Document | Where to obtain it |
|---|---|
| The tax return form | Tax office / Kokuzeichō website |
| Income-and-expense statement / blue-return settlement statement | Tax office / Kokuzeichō website |
| Withholding tax statement (源泉徴収票, gensen chōshūhyō) | Your employer |
| Real estate sale-and-purchase agreement | Received at the time of purchase |
| Fixed asset tax payment notice | Mailed by the municipality |
| Loan amortization schedule | The lender |
| Fire insurance policy | The insurance company |
All filing-related documents, including expense receipts, must be retained for seven years. Among the properties we manage, February is reliably when questions about annual income-and-expense records spike. Owners whose monthly management reports are already formatted for direct use in tax filing find this season far less demanding. If you'd like to rethink your management setup with this in mind, see: Building a System That Reduces the Burden of Rental Property Management.
What Happens If You Don't File?
Where filing was legally required and skipped, penalties are added on top of the original tax owed:
- Mushinkoku kasanzei (無申告加算税, non-filing penalty): 15–20% of the tax due is added.
- Kashō shinkoku kasanzei (過少申告加算税, under-reporting penalty): applies when the filed amount was less than the actual tax owed.
- Entaizei (延滞税, late-payment interest): accrues daily from the day after the filing deadline until the tax is actually paid — the longer the delay, the larger the amount.
- Jūkasanzei (重加算税, heavy additional tax): where the tax office determines the omission was intentional concealment, this steep 35–40% penalty applies instead of the standard non-filing penalty.
The moment an omission is discovered, filing an amended return (修正申告, shūsei shinkoku) stops the late-payment interest from continuing to grow. Because every day of delay makes the outcome worse, acting early is consistently the lower-cost path, even for owners managing property from a different country and time zone.
Points to Get Right Before You File
- Nenmatsu chōsei (年末調整, the year-end payroll adjustment) does not substitute for it: even a salaried employee whose employer handles year-end payroll adjustment still needs a separate kakutei shinkoku if they have rental income.
- Gather documents early: reissuing a withholding statement or other records can take time. Checking what you already have on hand in January, well before the filing window opens, avoids a February scramble.
- Avoid over-claiming expenses: spending unrelated to the rental business, or transportation and entertainment costs you cannot explain, are exactly what draws a tax office inquiry. Disciplined, defensible expense records also matter for how favorably banks view you when you next seek financing.
- Cross-check against landlord-tenant rules: operational decisions like genjō kaifuku (原状回復, restoration-to-original-condition) at move-out or rent adjustments also affect your tax outcome. Understanding Japan's Legal and Regulatory Framework for Rental Property Management makes it easier to justify the expenses you claim.
Where to Turn When You Need Help
Not trying to handle everything alone is, in practice, the most effective tax-saving move available. There are three standard places to turn:
- The tax office consultation desk: free advice, including guidance on how to fill out the forms.
- A licensed tax accountant (税理士, zeirishi): effective once judgment calls get complex, such as managing multiple properties or structuring tax planning.
- Tax filing software: lets you build a return simply by following on-screen prompts, and pairs particularly well with the double-entry bookkeeping that aoiro shinkoku requires.
Summary
Tax on Japanese rental income has to be understood as a system, not a single tax: national income tax and resident tax sit at the center, but consumption tax and fixed asset tax are part of the same picture. What's actually taxed is not gross rent but fudōsan shotoku (不動産所得) — rental income minus deductible expenses. Get three things right — correctly distinguishing deductible from non-deductible expenses, meeting the requirements for aoiro shinkoku, and filing on time — and the amount you actually keep changes meaningfully. Because Japanese tax law is revised on an ongoing basis, always confirm current-year rates and deduction amounts on the Kokuzeichō website before making a filing decision. When a judgment call is genuinely unclear, consult a zeirishi (税理士) or INA&Associates.
Frequently Asked Questions
Do I need to file a tax return if my rental income is 200,000 yen or less?
If you're a salaried employee, a national income tax return is not required, but a separate resident tax filing still is. And if the property operated at a loss, filing is actually advantageous — son'eki tsūsan (損益通算) lets you offset that loss against salary income and receive a refund.
Do I need to file even if I own just a single condominium unit?
It can be. The deciding factor is not the number of units you own but the amount of income: for a salaried employee, it comes down to whether real estate income exceeds 200,000 yen (approx. USD 1,300) a year. Even below that threshold, a separate resident tax filing is still required.
What expenses are not deductible against rental income?
The principal-repayment portion of a loan, income tax and resident tax themselves, and personal living expenses for any self-occupied portion of the property are all non-deductible. Qualification costs unrelated to the rental business, and unexplained or excessive transportation and entertainment expenses, also draw scrutiny.
Should I choose aoiro shinkoku or shiro shinkoku?
As a general rule, aoiro shinkoku is the stronger choice. At the gotō jisshitsu kijun scale — 5 buildings or 10 units — it unlocks the full 650,000-yen (approx. USD 4,200) special deduction and a three-year loss carryforward. Even at a smaller scale, the 100,000-yen (approx. USD 650) deduction is still available, which makes filing the approval application in advance worthwhile.
