Japan Real-Estate Contract Stamp Duty in 2026: What Buyers Pay
For real-estate transfer contracts created through March 31, 2027, Japan continues reduced stamp-duty rates for qualifying documents over ¥100,000; the tax depends on the contract amount written in the document, and a signed duplicate can itself become taxable.
Japan’s stamp duty (印紙税) on a real-estate sale contract is a tax on the document, not a percentage of the property’s assessed value. For qualifying real-estate transfer contracts created through March 31, 2027, the National Tax Agency continues reduced stamp-duty rates when the amount written in the contract exceeds ¥100,000.
The practical buyer trap is that document handling matters: a signed “copy” or duplicate can itself become a taxable document if it was created to prove the contract. That makes stamp duty a small line item compared with acquisition or registration tax, but an easy one to mishandle at signing.
The 2026 rule in plain English
The National Tax Agency classifies real-estate sale agreements as taxable documents. The amount of tax depends on the contract amount stated in the document.
For qualifying real-estate transfer contracts over ¥100,000 created between April 1, 2014 and March 31, 2027, reduced rates apply under the current relief.
That relief is time-limited, so a contract created after March 31, 2027 should not be budgeted using the current reduced table unless the law is extended again.
Stamp duty is based on the written contract amount
Do not confuse stamp duty with registration tax or annual property tax.
For a normal real-estate sale contract, the NTA says the relevant stated amount is generally the sale amount written in the document. If a document states that land worth ¥6 million is being sold for ¥5 million, the stated amount for stamp-duty purposes is ¥5 million.
That means the tax base is not the fixed-asset assessed value used for registration and license tax, and it is not the annual taxable standard used for fixed-asset tax.
Current reduced rates buyers commonly encounter
Under the NTA’s current real-estate relief table, common reduced stamp-duty amounts include:
- over ¥100,000 up to ¥500,000: ¥200
- over ¥500,000 up to ¥1 million: ¥500
- over ¥1 million up to ¥5 million: ¥1,000
- over ¥5 million up to ¥10 million: ¥5,000
- over ¥10 million up to ¥50 million: ¥10,000
- over ¥50 million up to ¥100 million: ¥30,000
Higher contract amounts continue on the NTA’s published table.
For many home purchases, the stamp-duty amount is therefore modest relative to the property price, but it still belongs in the closing-document workflow.
A worked example
Assume a buyer signs a paper sale contract for a Japanese home with a stated price of ¥32 million in 2026.
Under the current reduced table, a real-estate transfer contract over ¥10 million and up to ¥50 million carries ¥10,000 of stamp duty.
This ¥10,000 is not calculated from the property’s assessed value and is separate from:
- real-estate acquisition tax;
- registration and license tax;
- fixed-asset and city-planning tax;
- brokerage, judicial-scrivener and lender fees.
For those other transaction taxes, see Engawa’s 2026 registration-tax guide and 2026 acquisition-tax guide.
The duplicate-copy trap
A common assumption is that only the document labelled “original” can be taxable.
The NTA says that a document labelled copy, duplicate or transcript can still be a taxable contract when its form shows that it was created to prove the agreement. A duplicate bearing the parties’ signatures or seals is a classic example.
So if buyer and seller each keep a separately executed paper counterpart, do not assume one of them is automatically outside stamp duty merely because it says “copy.”
The correct treatment depends on how the documents are created and used.
Why document form matters
Stamp duty applies to taxable documents. That makes the contract-production method important in a way that is different from transaction taxes triggered by the acquisition itself.
Before signing, ask the broker or legal professional handling the transaction:
- how many executed paper originals or counterparts will be created;
- who will retain each executed document;
- which documents require revenue stamps;
- whether any separately signed duplicate could itself count as a taxable document.
This is a procedural question worth resolving before execution rather than after the parties have already created multiple signed copies.
Do not mix stamp duty with registration tax
These taxes sound similar because both can arise near closing, but they answer different questions.
Stamp duty taxes specified documents based on their contents and stated amount.
Registration and license tax arises when ownership, mortgage and other rights are registered, generally using the fixed-asset-tax assessed value for real-estate ownership registrations or the secured claim amount for a mortgage.
A buyer’s closing estimate should therefore keep the two on separate lines.
Buyer checklist before contract signing
Before the sale agreement is executed:
- Confirm the stated purchase price in the contract.
- Check the current NTA stamp-duty band for that amount.
- Confirm the contract creation date because the current reduced real-estate rates run only through March 31, 2027 under published law.
- Ask how many executed paper counterparts will exist.
- Do not assume a signed duplicate is tax-free.
- Keep stamp duty separate from acquisition, registration and annual property taxes in the transaction budget.
- Have the broker, judicial scrivener or tax professional confirm unusual document structures before execution.
For an all-in estimate, use Engawa’s Japan closing-cost calculator, then verify the actual document tax against the signed contract structure.
