Invoicing and the Qualified Invoice (Inbosu) System
The Qualified Invoice System Japan introduced in October 2023 controls whether a corporate client can claim consumption-tax credit on your freelance invoice.12 If your buyers are taxable businesses, your registration status now shapes every fee negotiation.
Procedures, fees, and requirements can change. Confirm current details at the National Tax Agency invoice system site. This article is general information, not legal, tax, or immigration advice; for your specific case, consult a licensed tax accountant (税理士, zeirishi).
Overview
This article is for freelancers who invoice corporate clients for services performed in Japan and whose annual taxable sales sit at or below 10M yen.3 It covers the national qualified-invoice regime, the registered-issuer number, and the register-or-stay-exempt decision.
The regime is uniform nationwide. Consumption tax is national law administered by the National Tax Agency, so no ward or city office applies a local variant.12 What varies company to company is commercial negotiation, not the tax rule itself.
Whether you may freelance at all depends on your status of residence, which this article does not decide. It assumes you are already permitted to work as a sole proprietor and focuses only on invoicing mechanics.
Who this affects most
The heaviest impact falls on business-to-business (B2B) sellers whose buyers are taxable enterprises.12 Those buyers need a qualified invoice from a registered issuer to claim their input credit, so an unregistered freelancer's invoice costs the client money even when the fee looks identical.
Sellers whose buyers are final consumers face a different calculus. Consumers and exempt buyers hold no input credit to lose, so registration pressure tracks your client mix rather than your revenue alone.2
How the system changed B2B consumption tax
Before and after October 2023, a taxable business computes payable tax the same way: output tax collected on sales minus input tax paid on purchases and expenses.14 The invoice system changed the evidence required for the subtraction, not the subtraction itself.
Under the new method, the buyer-side credit generally requires retaining prescribed books plus the qualified invoice itself.12 A purchase without a qualified invoice generally yields no credit, which is why the seller's registration status now travels with every B2B invoice.
The following picture shows the credit chain from the buyer's side.
What buyers need to claim the credit
The buyer must receive a qualified invoice from a registered issuer and retain it with the prescribed books, except in statutorily difficult cases.12 Buyers computing under simplified taxation or the 2割特例 (niwari tokurei, "20 percent special measure") do not need to retain received invoices for the computation itself.12
Transitional relief softens the landing. For purchases from exempt and other non-issuer sellers made from 1 October 2023 to 30 September 2029, the buyer may credit a fixed proportion of the deemed input amount (80 percent and 50 percent bands; confirm current figures with the National Tax Agency, as of 2025-04-01).2 A further standing relief lets buyers credit a fixed proportion of deemed input without invoice retention through 30 September 2031 (as of 2025-04-01).1
That relief is capped per supplier. For taxable periods starting on or after 1 October 2024, purchases from a single exempt seller above 1B yen tax-inclusive per year or fiscal year lose transitional coverage on the excess (as of 2025-04-01).2 Most freelancers never approach that line, but corporate clients with concentrated outsourcing check it.
What a qualified invoice must show
A qualified invoice is not a fixed government form.12 Any document carrying the prescribed items counts, whether it is titled an invoice, a receipt, a delivery slip, or structured data.
Each invoice must carry six items: the recipient's name, your name plus registration number, the transaction date, the transaction detail (flagging reduced-rate items), the total consideration per rate plus the applicable rate, and the consumption-tax amount per rate (as of 2025-04-01; confirm current figures with the National Tax Agency).15 Missing any item means the document is not a qualified invoice, even when the fee and total look correct.
As an issuer you must deliver a qualified invoice when a taxable counterparty requests one, except where delivery is statutorily difficult.2 You must also retain a copy of every invoice you issue, generally for 7 years from two months after the day following the end of the relevant period (as of 2025-04-01).5
The T-prefix registration number
Only a business registered by the competent tax office may issue qualified invoices.2 After screening, the tax office notifies your registration number (登録番号, tōroku bangō, "registration number") and publishes the number with your name on the public disclosure site.2
The number takes two shapes. Businesses holding a corporate number receive T plus the corporate number, while all other businesses (including sole proprietors) receive T plus 13 digits.2 Clients use this number to verify your issuer status on the disclosure site before booking the credit.
A one-minute disclosure-site check at onboarding prevents a common first-invoice rejection, where accounts payable holds payment because the T-number on the invoice does not yet resolve. Send the number with your first invoice and invite the check.
Terminology
- 適格請求書 (tekikaku seikyūsho, "qualified invoice"), commonly shortened to インボイス (inboisu, "invoice") 2
- 適格請求書発行事業者 (tekikaku seikyūsho hakkō jigyōsha, "qualified invoice issuer") 2
- 登録番号 (tōroku bangō, "registration number") 2
The under-10M exemption and the new pressure to register
Businesses whose base-period taxable sales are 10M yen or less are generally exempt from consumption-tax liability.3 For a sole proprietor, the base period is the year before last, so 2024 sales decide 2026 status under the ordinary rule.3
Registration defeats that exemption. A registered issuer owes consumption tax regardless of base-period sales.23 An exempt freelancer who registers mid-period becomes taxable from the registration date to the period end for sales in that span under the transitional measure covering periods that include 1 October 2023 to 30 September 2029.23
This differs from the ordinary taxable-enterprise election, which generally takes effect from the following period.3 Invoice registration under the transitional measure takes effect from the registration date itself, so the timing choice has immediate filing consequences.
| Item | Status | Detail |
|---|---|---|
| Base-period sales 10M yen or less, unregistered | Exempt | No consumption-tax filing duty under the ordinary rule3 |
| Registered issuer, any base-period sales | Taxable | Filing and payment duties apply; simplified regimes below soften computation only23 |
| Exempt seller's invoice to a taxable buyer | No buyer credit | Buyer absorbs the embedded tax outside the relief bands covered above2 |

Why clients care whether you are registered
Where you are unregistered, your taxable client cannot credit the consumption tax embedded in your fee (outside the transitional bands and simplified regimes).2 The client absorbs that cost, which is why procurement teams now ask every freelancer for issuer status before renewing a contract.
That commercial consequence has no statutory price tag. No NTA source fixes a renegotiation outcome such as a flat percentage cut, so any "rate difference" arithmetic in a negotiation is illustration, not a tax-office bill.2
NTA sources establish only the lost-credit mechanism, not a fixed discount rate. Presenting a fee reduction as legally required overstates the source and weakens your position if the client checks.
Register or not: the decision framework
Registering converts you into a taxable enterprise with consumption-tax filing and payment duties.12 Two relief regimes reduce the computation burden without removing the filing duty: the 2割特例 for newly registered small businesses and simplified taxation for qualifying small sellers.26
The 2割特例 lets a small business that newly registered at the invoice-system opportunity pay 20 percent of output tax instead of computing actual input (covering periods falling between 1 October 2023 and 30 September 2026) (as of 2025-04-01; confirm current figures with the National Tax Agency).24 Simplified taxation lets a qualifying issuer compute input tax from output tax using a deemed purchase rate, with service freelancers in the 5th category using 50 percent, available where base-period sales are 50M yen or less and a prior election was filed (as of 2025-04-01).6
The decision turns on client mix rather than pride in the number. Map your revenue before choosing, then revisit when the mix shifts.
Register and pay consumption tax
Registration is the stable path where most revenue comes from taxable corporate clients who value the input credit.2 You preserve the client's credit at the cost of becoming taxable, which keeps renewals procedural rather than renegotiated line by line.
After registering, you take on issuer duties beyond the number itself. You must issue on a valid taxable-counterparty request and retain copies, and failure to issue on request breaches an issuer duty.2
Stay exempt and negotiate the difference
Staying exempt remains lawful.2 You simply cannot issue qualified invoices, and each taxable client decides how to handle the lost credit: absorb it, renegotiate the fee, or move the work elsewhere.
Because no source fixes the outcome, frame the talk around arithmetic rather than statute. Show the client the embedded-tax illustration for your fee band, invite their procurement rule, and record whatever you agree in the contract rather than in the invoice memo.
How to register and start issuing
Registration means filing the invoice-issuer registration application (適格請求書発行事業者の登録申請書, tekikaku seikyūsho hakkō jigyōsha no tōroku shinseisho, "registration application") with your competent tax office.2 The e-Tax web version walks through the form in question-and-answer format, while paper filing remains available.27
E-Tax use needs advance preparation: a digital certificate such as a My Number Card plus a user identification number.2 After screening, the tax office notifies your registration number and publishes the number with your name on the public disclosure site.2
Becoming an issuer pulls your sales from the registration date into the consumption-tax return. Budget for the filing itself (and for professional fees if you outsource it), not only for the invoice template change.
Registration timing and effective date
Under the transitional measure for periods including 1 October 2023 to 30 September 2029, an exempt business that registers becomes an issuer from the registration date.2 The ordinary taxable-election timing from the following period does not apply to this path.3
Because this research pass could not verify a standard day-count lead time in fetchable NTA text, this article states no fixed application lead time. File early with your competent tax office and confirm the effective date on your notice rather than counting backwards from a desired invoicing date.
Good to know
A corporate client discount request is negotiation, not a tax bill
A demand framed as "10 percent off because of the invoice system" cites no statute. NTA sources establish only that the buyer loses the input credit outside the relief bands; they fix no discount rate.2 Treat the request as commercial negotiation, compare it against what the client relationship is worth, and get any agreed adjustment into the contract terms.
Registering mid-year pulls sales into the tax return
Registration is not a template change alone. It defeats the under-10M exemption and pulls period sales from the registration date into the consumption-tax return.23 The 2割特例 and simplified taxation soften the computation but leave the filing duty itself in place, so price the compliance cost (bookkeeping time or accountant fees) before registering.246
B2C-only sellers face a different calculus
Where buyers are final consumers or exempt businesses, no input credit exists to lose.2 A designer selling only to individuals or an instructor billing only exempt schools faces structurally less registration pressure than a subcontractor billing taxable agencies. Revisit the choice if your mix shifts toward corporate work.
Transitional relief expires on fixed dates
Buyer-side relief for non-issuer purchases covers 1 October 2023 to 30 September 2029, with the 1B-yen-per-seller annual cap applying from periods starting on or after 1 October 2024 (as of 2025-04-01; confirm current figures with the National Tax Agency).2 Seller-side 2割特例 relief covers periods falling between 1 October 2023 and 30 September 2026 (as of 2025-04-01).24 Calendar checks beat memory; confirm current figures with the National Tax Agency before quoting dates to a client.
