# The 20.42% Nobody Budgeted For: Withholding Tax on Japanese Rental Income for Overseas Owners
Most overseas buyers model their Japanese rental yield on gross rent minus expenses. Then the first payment arrives and it's 79.58% of the figure in the lease.
Nothing has gone wrong. This is Japanese withholding tax on domestic-source income, and if your tenant is a company, it applies automatically. What surprises people is not that the tax exists — it's that it's deducted from gross rent rather than profit, and that most owners eventually get a large chunk of it back.
Here is how the rule actually works, when it bites, and what to do about it.

## The rule in one paragraph
Rent paid for real estate located in Japan to a non-resident individual or a foreign corporation is domestic-source income. The person paying the rent must withhold 20.42% at source and remit it to the tax office by the 10th of the following month. The landlord receives 79.58%.
The 20.42% breaks down as:
- 20% national income tax
- Plus the 2.1% special reconstruction surtax applied on top of that (20% × 1.021 = 20.42%)
The obligation sits on the payer, not the owner. Your tenant is the withholding agent. If they get it wrong, the tax office pursues them.

## The exemption that decides everything
There is one carve-out, and it does most of the practical work:
- No withholding is required where the tenant is an individual who is renting the property to live in themselves, or for a relative to live in.
Read the conditions carefully, because both halves matter:
- The tenant must be an individual, not a company
- The use must be residential, for the tenant or a relative
An individual renting your unit as an office, a studio, or a base for their sole proprietorship does not qualify. The exemption is about residential use by a natural person, not about the tenant's size.
So in practice:
- Apartment let to a private individual as their home: no withholding, you receive 100%
- Same apartment let to a company as employee housing: withholding applies
- Office, retail unit, warehouse, or whole-building commercial lease: withholding applies
- Land leased to a company: withholding applies

## Where it catches people out
Master lease and sublease arrangements
This is the one that surprises even experienced owners. If you put your residential unit into a master lease or sublease with a management company, that company is now the party paying you rent. It is a corporation. The individual-residential exemption looks at who pays you, not at who ultimately occupies the unit.
- Result: a purely residential property under a sublease arrangement is subject to 20.42% withholding, even though a direct lease to the same occupant would not be.
Key money and premiums
Withholding is not limited to monthly rent.
- Non-refundable key money and lease premiums are treated the same way and are subject to withholding when paid
- Refundable security deposits are not, while they remain refundable — but any portion later retained by you rather than returned changes character at that point
Becoming non-resident mid-tenancy
The most common failure in the market. An owner lives in Japan, signs a lease, then relocates overseas. From the date they become non-resident, withholding is required — and the tenant usually has no idea.
- The change is often never communicated by the management company
- The tenant under-withholds for months or years without knowing
- When it surfaces, the tenant faces back tax, a penalty for failure to withhold, and late payment interest
- They will then come to you for reimbursement, and that conversation is rarely pleasant
If you are moving abroad and keeping a tenanted property, notifying the tenant and the management company is not a courtesy. It protects you from a claim later.

## The part most owners miss: this is not your final tax
The 20.42% is a payment on account, not a settlement. It is calculated on gross rent because the tax office has no visibility into your expenses at the point of payment. Your actual liability is calculated on net rental profit when you file.
Deductible against your rental income:
- Depreciation on the building portion
- Loan interest
- Fixed asset tax and city planning tax
- Management and leasing fees
- Repairs and maintenance
- Insurance premiums
- Accounting and tax agent fees
Depreciation is usually the decisive item. Japanese buildings depreciate on short statutory lives, and second-hand properties are often on a heavily shortened remaining life. Taxable profit routinely comes in far below gross rent — which means 20.42% of gross frequently overshoots the real liability.
A rough illustration for a property let to a corporate tenant:
- Gross annual rent: 10,000,000 yen
- Withheld at source over the year: 2,042,000 yen
- Deductible expenses: 3,000,000 yen
- Blue return deduction, where available: 650,000 yen
- Resulting taxable income: roughly 5,900,000 yen
- Income tax plus surtax on that: roughly 760,000 yen
- Refund on filing: roughly 1,280,000 yen
In this example the owner has advanced the Japanese government more than 1.2 million yen interest-free for up to fifteen months. That is a real cash flow cost, and it is entirely recoverable — but only if you file.
One note on the blue return deduction: the larger deduction requires your holding to reach business scale under the standard test, roughly five detached buildings or ten rental units, together with proper bookkeeping and electronic filing. Below that threshold the deduction is much smaller. Owners of a single unit should not assume it.

## What you need to have in place
A tax agent in Japan
Non-residents must appoint a tax administrator and file the notification with the relevant tax office. This is the person who receives correspondence, files on your behalf and handles payment or refund. Without one, you have no functioning channel with the tax authority and refunds have nowhere to go.
An annual filing
- The filing window runs from 16 February to 15 March for the preceding calendar year
- Non-residents with Japanese-source income above the available deductions are required to file
- This is also the only mechanism by which over-withheld tax is refunded
A Japanese bank account, ideally
Refunds and rent both need somewhere to land. Opening an account as a non-resident is considerably harder than opening one while still resident, which is a strong argument for doing it early.
Withholding exemption certificate
A certificate relieving the payer of the withholding obligation does exist, but it is aimed at non-residents carrying on business through a permanent establishment in Japan. A passive overseas owner of one or two units will generally not qualify. Worth asking about if your holdings are substantial; not worth building a plan around otherwise.

## Tax treaties will not help you here
Owners from Hong Kong, Singapore, Taiwan and elsewhere often assume a treaty will reduce or eliminate the 20.42%. It will not.
Under the standard treaty article on income from immovable property, the country where the property sits retains the right to tax. Japan's treaty network follows this. There is no reduced rate to claim and no benefit in filing a treaty application form for rental income.
Where a treaty may matter is on your home-country side, in relieving double taxation through a foreign tax credit. That is a question for your own advisers, not for the Japanese tax office.

## The parallel rule on sale
The same logic applies when you exit, at a different rate.
- Sale of Japanese real estate by a non-resident: the buyer withholds 10.21% of the gross sale price
- Exemption: where the buyer is an individual acquiring the property as a residence for themselves or a relative, and the price is 100 million yen or less
Note that this is 10.21% of the sale price, not of the gain. On a 50 million yen sale that is 5.1 million yen withheld regardless of whether you made a profit. You recover the excess by filing, but you should plan your cash position around the gross figure, not the net.
A corporate buyer never qualifies for the exemption, whatever the price or the intended use.

## Is there a way around it?
Holding through a Japanese company is the structural answer, because a domestic corporation is not a non-resident and rent paid to it is not subject to withholding. It also opens up corporate deductions and a different treatment on exit.
But it is not free:
- Corporate income tax filings each year, with accountant fees to match
- Per-capita local tax payable even in a loss-making year, typically around 70,000 yen at the minimum
- Formation costs, a registered address, and a representative
- Different, and not always better, treatment of capital gains on sale
For a single small unit this rarely pays for itself. For a portfolio, a hotel asset, or a commercial building with corporate tenants, it usually deserves a proper look before acquisition rather than after.

## Looking ahead to 2027
The reconstruction surtax that produces the 0.42% portion is being restructured from January 2027. The rate drops from 2.1% to 1.1%, with a new 1% defence surtax introduced alongside it.
- The combined add-on stays at 2.1%
- The withholding rate on rent therefore remains 20.42%
- The reconstruction surtax period is extended by ten years, so the long-run total is higher even though the annual rate is unchanged
Nothing in your rent calculation changes. It is worth knowing so that a change in the wording on your withholding statements does not cause alarm.
---
## The practical takeaway
- If your tenant is a company, expect 79.58% and plan cash flow accordingly
- If your tenant is an individual living there, expect 100% and check that nobody is withholding by mistake
- If you are in a sublease arrangement, expect withholding regardless of who occupies the unit
- Whichever applies, appoint a tax agent and file annually. The withheld amount is very often more than you actually owe, and the only way it comes back is through a return
The 20.42% is not a tax on foreign owners. It is a collection mechanism, and treating it as a permanent cost rather than a timing difference is what turns an inconvenience into a genuine loss of yield.
