Client-Side Withholding (Gensen Choshu)

Client-side withholding (Gensen Choshu) is the system where your Japan-based client deducts income tax from your freelance fee before paying you and remits it to the tax office on your behalf.¹ The transfer that arrives is smaller than the invoice, and the missing slice is a prepayment of your own income tax, not a client discount or platform fee.¹²

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at the National Tax Agency 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 receiving payments from Japan-based clients who want to understand why part of the invoice never arrives and what happens to it next.³¹ It covers resident individuals providing withholding-subject services inside Japan, which is the common freelance case.³

The mechanism is national Income Tax Act law, so there is no ward or city variance in the rates or the payer duty.³¹ One boundary still varies by person: tax residence turns on domicile and length of stay, not on visa label or nationality alone, and non-resident Japan-source payments follow a different withholding framework with possible treaty relief that this article does not cover.⁴

Which payments trigger withholding

Only certain payment types trigger withholding. The question is never whether you issued an invoice; it is whether the underlying work falls into a category the law lists.³⁵

Payment types on the defined list

For resident recipients, the listed range includes manuscript and lecture fees, fees to holders of specified qualifications such as attorneys, certified public accountants, tax accountants, and judicial scriveners, entertainment and performance fees, and the remaining categories on the scope page.³ Translation, writing, lecture, and design work fall inside the manuscript-fee and design-fee group that freelancer guidance treats as the main withholding-subject categories.³⁶²

Labels do not control the outcome. Amounts paid under names such as honoraria, research, interview, or travel-equivalent fees are still subject when their substance matches remuneration, and payment in goods or other economic benefit counts the same as cash.³ Two carve-outs matter in practice. Exam-question drafting and answer-grading fees are excluded from manuscript fees.⁶ Prize money to contest winners and reader-column contributions counts as manuscript fees in principle, but a single payment of 50,000 JPY or less to one person may skip withholding (as of 2025-04; confirm current figures with the National Tax Agency).³⁶

Amounts a payer remits directly to a carrier or hotel for ordinary-range travel and lodging sit outside remuneration, and the same exclusion applies to professional-fee payments for ordinary-range transport and lodging paid straight to the provider.³⁷

Terminology

• 源泉徴収 (gensen chōshū, "collection at the source; withholding at source")¹
• 報酬・料金等 (hōshū ryōkin-tō, "remuneration and fees")³
• 源泉徴収義務者 (gensen chōshū gimusha, "withholding agent; person obliged to withhold")¹

Who must withhold and when no withholding applies

Any payer of withholding-subject income, including companies, cooperatives, unincorporated associations, and individuals, is a withholding agent.¹ In practice your client is usually a company, so the duty clearly applies.

An individual payer who is not a salary payer, or who pays salaries only to two or fewer live-in domestic workers, need not withhold on professional remuneration except for hostess-type payments.⁸ A salaried employee who pays a tax accountant for a personal return is the worked example: no withholding is required there.¹ So the same service can carry withholding from a corporate client and none from a private client, and that asymmetry is normal.⁸¹

Service-fee payments to a domestic corporation sit outside this resident-individual scope; the only corporation-recipient case listed is the racehorse prize paid to a corporate racehorse owner.³

How the 10.21 percent rate works

The 10.21 percent rate combines 10 percent income tax with the 2.1 percent reconstruction special income tax surcharge, and the 20.42 percent rate combines 20 percent with the same surcharge (as of 2025-04; confirm current figures with the National Tax Agency).¹ The surcharge applies to income arising from 2013-01-01 through 2037-12-31 and is collected together with the income tax.¹

The 1M JPY threshold and the 20.42 percent portion

The threshold applies per single payment amount, labeled 支払金額 (=A) in the rate table (as of 2025-04).⁶ A series of 500,000 JPY invoices each uses the 10.21 percent rate even when the yearly total passes 1M JPY, because each payment is measured on its own.⁶

Payment amount A (single payment)	Withholding	As of	Notes
1M JPY or less	A x 10.21 percent	2025-046	Standard freelance case
Above 1M JPY	(A minus 1M JPY) x 20.42 percent + 102,100 JPY	2025-046	Excess portion uses the higher rate
Example: 1.5M JPY manuscript fee	204,200 JPY	2025-046	(1.5M minus 1M) x 20.42 percent + 102,100 JPY

The table above states the full 2025-04 rate picture; confirm current figures with the National Tax Agency before relying on it for a large invoice. Fractions under one yen in the computed tax are rounded down, never up (as of 2025-04).⁶⁷

A single large payment jumps the deduction discontinuously

Once one payment crosses 1M JPY, every yen above the line uses 20.42 percent (as of 2025-04).⁶ Milestone sizing is a commercial decision, not a withholding election, so price a 1.2M JPY single invoice with the higher slice in mind.

Consumption-tax handling on the withholding base

When the remuneration amount includes consumption and local consumption tax, the tax-inclusive amount is the withholding base in principle.³⁶⁷ When the invoice clearly separates the fee from the consumption-tax amount, the fee alone may serve as the base.³⁶⁷ This separation treatment is unchanged after the Qualified Invoice system launch.³⁶

The Qualified Invoice system governs consumption-tax input credits, not income-tax withholding, so invoice registration neither creates nor removes withholding liability.⁵

An unseparated invoice raises the withholding on the same deal

Two invoices for identical work produce different net transfers when one separates consumption tax and the other does not, because the unseparated one is measured tax-inclusive (as of 2025-04).³⁶ Always break the fee and the tax onto separate lines.

What your client does after withholding

Your client calculates the tax at payment time, subtracts it from your fee, and remits it to the tax office on your behalf.¹ The payer-side process closes with a withholding record delivered to the recipient and submitted to the tax office.⁴

Remittance timing and the record you receive

The client remits withheld income and reconstruction tax by the 10th of the month following payment, via e-Tax or the designated calculation form at a financial institution or tax office (as of 2025-04; confirm current figures with the National Tax Agency).⁶¹ Manuscript and lecture-fee withholding is not eligible for the semi-annual special deadline.⁶

Attorney and professional-fee withholding follows the same 10th-of-next-month rule in principle (as of 2025-04).⁷ Payers approved for the special deadline remit January to June amounts by July 10 and July to December amounts by January 20 of the next year (as of 2025-04).⁷

The yearly document that matters to you is the payment record (支払調書, shiharai chōshū), which the client files with the tax office and will usually share on request for return preparation.² Filing remains possible from your own invoice and payment records even without it.²

Ask for the yearly payment record before filing season

Clients file the payment record with the tax office but do not always volunteer a copy.² Request it early and cross-check its withheld totals against your own invoices before you file.

Terminology

• 支払調書 (shiharai chōshū, "payment record; statement of payments and withholding")²
• 復興特別所得税 (fukkō tokubetsu shotokuzei, "reconstruction special income tax")¹

How to format the invoice

Clients expect a fixed line-item order: gross service fee, separately stated consumption tax, subtotal, withholding-tax deduction line, net transfer amount.² This layout is convention, not a National Tax Agency prescribed form, but it is what makes the deduction legible to both sides.² No law requires you to print the withholding line, yet recording it prevents payment delays and eases return-time verification against the client's payment statement.⁵

Line	Example amount	As of	Notes
Service fee	500,000 JPY	2025-042	Withholding base when separated
Consumption tax (10 percent)	50,000 JPY	2025-042	Stated separately, excluded from base
Subtotal	550,000 JPY	2025-042	Commercial total
Withholding (10.21 percent of fee)	minus 51,050 JPY	2025-0462	Rate per NTA table
Amount due	498,950 JPY	2025-042	Transfer the client sends

The illustration above reflects 2025-04 rates; confirm current figures with the National Tax Agency when you price a real invoice. Omitting the separate consumption-tax line forces the tax-inclusive base, which raises the withholding on the same commercial deal (as of 2025-04).³⁶

Reconciling at year end through kakutei shinkoku

Withholding is a prepayment, not the final tax. The annual return covers January 1 to December 31 income and computes the final liability, and withheld tax plus any prepaid estimated tax is settled for over or shortfall through that return.⁹ Where withheld tax exceeds the computed annual liability, filing the return produces a refund of the excess through the refund-return mechanism.¹⁰

The standard return window runs February 16 to March 15 of the following year, with March 15 as the deadline (as of 2025-04; confirm current dates with the National Tax Agency).⁹ A refund-only return may be filed from January 1 of the next year up to five years out, except where a deadline-bound provision such as the blue-form special deduction requires filing by the statutory deadline (as of 2025-04).¹⁰

Freelancers resolve the balance through this return, not through an employer year-end adjustment.⁹⁴ Without a return there is no mechanism for excess withholding to come back.⁹¹⁰

Terminology

• 確定申告 (kakutei shinkoku, "final income-tax return")⁹
• 還付申告 (kanpu shinkoku, "refund return filed to claim overpaid tax")¹⁰

Good to know

A withheld amount is not your final tax bill

Readers often treat the 10.21 percent deduction as a final levy (as of 2025-04).⁶ It is settled against the computed annual liability, with a refund when withholding exceeds it.⁹¹⁰ Budget against the net transfer during the year and let the return decide the final number.

Design-labeled work can still trigger withholding on part of the fee

A contract labeled system development or consulting can still contain a withholding-subject slice of manuscript, design, or guidance substance.³ The scope rule applies substance over label, so embedded planning or structure work can pull that slice into withholding even when the headline deliverable would not trigger it on its own.³²

A private-client payment may carry no withholding at all

An individual payer who is not a salary payer owes no withholding on professional remuneration.⁸¹ Do not read a missing deduction from a private client as an error, and do not expect one where none is due.

Ask for the payment record before filing season

The payment record exists to cross-check withheld totals at filing.² Request it before the February rush, reconcile it against your invoices, and file from your own records if a client is slow.²
