Electronic contracts and Japan’s stamp duty: is a stamp needed?
Why an electronic contract needs no Japanese revenue stamp, when a printout or paper original becomes taxable, and which paper contracts still need one.
The short answer: an electronic contract needs no revenue stamp
A contract concluded and kept as electronic data needs no revenue stamp. In a published Q&A, Japan’s National Tax Agency says stamp tax applies only to the “documents” in the table of taxable documents and an electronic record is not a document, so a record e-mailed to a counterparty is not taxed. A signed PDF or a contract signed online is the same.
If a freelance designer and a client sign a service agreement online, there is nothing to stamp; printed twice and sealed by both parties, it may count as a contract for work (class 2), taxed on the amount stated.
Only paper “taxable documents” are taxed
The Stamp Tax Act taxes the documents in its Appended Table 1 and makes their creator liable (Articles 2 and 3). A taxable document is one of the twenty listed kinds, made between the parties to prove what it records, and not exempt.
The NTA’s basic circular (section 44) says a taxable document is “created” when the taxable matter is put on paper and the paper is used for its purpose, such as handing it over; an electronic contract does neither, so no taxable event occurs. A 2008 Fukuoka Regional Taxation Bureau ruling confirms that e-mailing an order acceptance as a PDF creates no taxable document.
Printing a copy, and what counts as an original
Printing a signed electronic contract for your files triggers no tax. Tax Answer No. 7120 explains that a document sent by fax or e-mail stays with the sender as the original, so the recipient’s printout counts as a copy and is not taxable.
The same page warns that a copy becomes taxable if it carries the signature or seal of both parties or of the party other than its holder, or a party’s certification that it matches the original; sealing a printout again, or handing over a paper original after e-mailing the PDF, makes it taxable.
If you sign on paper: the classes that need a stamp
Whether a paper contract needs a stamp depends on its class: real-estate transfers (class 1), contracts for work such as construction contracts and order acceptances (class 2), basic agreements for continuing transactions such as an ongoing service agreement (class 7), and receipts for sales proceeds (class 17).
Amounts are set in bands by the sum stated; real-estate transfer and construction contracts created between 1 April 2014 and 31 March 2027 carry reduced rates; the NTA’s table of stamp tax amounts has the figures.
An NDA covering only confidential information is not taxed if it fits none of the twenty classes; the test is content, not title, so one that also commissions work or fixes a fee may be taxable.
What going electronic does not change
Stamp tax is separate from whether a contract was formed or can be proved; laws requiring paper or consent still apply. The Construction Business Act (Article 19) requires a construction contract’s terms to be written, signed or sealed and exchanged, and allows an electronic method only with the counterparty’s consent. The Freelance Act (Article 3, in force since 1 November 2024) requires a commission’s terms to be stated at once in writing or electronically and, with limited exceptions, a paper copy without delay if the freelancer asks after an electronic disclosure.
Record keeping also remains: a business that must keep books for tax and exchanges contract data electronically must keep that data under the Electronic Books Preservation Act’s electronic-transaction rules; a printout alone is not enough (see our record-keeping guide).
QuoteBill E-Contracts, and what to check before sending
QuoteBill E-Contracts creates a simple electronic signature with an audit trail and issues a signature certificate, QuoteBill’s own record, with an evidence file anyone can check. It is not an advanced or qualified electronic signature, does not verify who signs, is not a timestamp authority or a retention system certified under any law, and does not judge stamp tax; nothing here is legal or tax advice. Before moving a service agreement or an NDA online, check these points.
- Complete the contract as data; afterwards, do not hand over a printed original or seal and certify a printout.
- Check whether a law requires paper or consent, as for construction work or a freelance commission.
- Save the completed PDF and evidence file yourself under the electronic-transaction retention rules.
- If a document is hard to classify, ask the NTA’s consultation desk or a tax accountant.
