Freelance Taxes in Japan for Foreigners (2026): The ¥650,000 Deduction You May Have Already Forfeited

Information current as of April 2026 based on the National Tax Agency 2025 basic deduction reform page, NTA No.2072 Blue Return special deduction, NTA No.2795 withholding on professional fees, NTA qualified invoice (2-wari) transition measures, and Immigration Services Agency guidance on work-status visas.

Tax filing confuses Japanese nationals too. But foreign freelancers face three extra layers Japanese guides ignore: your visa may or may not allow freelancing, Japan's tax residency rules do not follow a simple 183-day test, and the invoice system rewired everyone's pricing in 2023. Instead of a generic explainer, this guide walks you through a decision flow. By the end, you will know which filer you are and what to actually do.

Step 1: Which kind of freelancer are you?

"Freelance" is not a legal category in Japanese tax law. The National Tax Agency only cares how your income is classified. Find yourself in this table:

Your situation	NTA income category	What you should file
You have a 開業届 on file and bill clients via 業務委託 as your main job	事業所得 (business income)	Full kakutei shinkoku, eligible for blue-return deductions
You have a salaried day job and side gigs (writing, coding, uploading to Adobe Stock, etc.)	雑所得 (miscellaneous) — or 事業所得 if sustained & at scale	Kakutei shinkoku only if side profit exceeds ¥200,000 (see Step 2)
Your client withholds 10.21% and sends you a 支払調書 but you have no 開業届	Usually 雑所得	File to reclaim the withheld tax
You work for an agency on a 業務委託 contract with set hours and one employer — and no other clients	Grey area — may be treated as 給与所得	Check your 源泉徴収票 vs 支払調書; one of them will clarify
You occasionally sell on Mercari or hobby commissions under ¥200,000	Usually not taxable	No filing required if you are a salaried employee

The 開業届 question: Filing the 個人事業の開業届 within one month of starting your business is legally required under Income Tax Act Article 229. There is no penalty for missing it, but you cannot claim the ¥650,000 blue-return deduction without being on record as a sole proprietor. If you earn meaningful freelance income, file the 開業届 retroactively — it takes 10 minutes at your local tax office or via e-Tax.

Step 2: Do you actually have to file?

Walk through this flow in order. Stop at the first "yes."

1. Do you have no salaried job and earned over the basic-deduction threshold (¥950,000–¥580,000 depending on income size) from freelancing? → You must file.
2. Do you have a salaried job plus freelance side income over ¥200,000 in total profit (income minus expenses)? → You must file.
3. Did a client withhold 10.21% under the 源泉徴収 rules? → Filing is not legally required in all cases, but you should file to get the money back.
4. Is your total income below every threshold above? → Filing is optional for national income tax, but 住民税 (resident tax) declaration is still required at your ward office even if 所得税 is not.

One important trap: the ¥200,000 rule only exempts national income tax. Residents still have to declare the side income to their municipality for resident tax. Skipping this is a very common foreign-resident mistake.

Step 3: Visa reality check — the part other guides skip

This is where foreign freelancers get blindsided. Your tax obligations are one thing; your right to earn the income in the first place is another. Before you file, confirm your status allows freelancing at all.

Your residence status	Can you freelance?	Notes
永住者 (Permanent Resident)	Yes, no restrictions	Freelance, sole-proprietor, run a company — all allowed
日本人の配偶者等 / 永住者の配偶者等	Yes, no restrictions	Business viability will be checked at visa renewal
定住者 (Long-Term Resident)	Yes, no restrictions	Same as above
技術・人文知識・国際業務	Conditional	Pure independent freelancing is not aligned with this status. 業務委託 with sufficient continuity and income within your specialty may be OK — immigration judges case-by-case at renewal. Side gigs outside your field need 資格外活動許可.
高度専門職 1号	Tied to your employer	Independent freelance generally not permitted. Related side work (lecture, teaching) needs 資格外活動許可.
経営・管理	Yes, but heavy requirements	Capital requirement jumped from ¥5M to ¥30M effective October 16, 2025, plus physical office and ≥1 full-time employee requirement strengthened. Rarely the right fit for a solo freelancer.
留学 (Student)	Only with 資格外活動許可	Hard cap of 28 hours per week, no principal-activity freelance

If your visa is on the "conditional" row and you are uncertain, talk to an immigration lawyer before filing large freelance income. Filing as 事業所得 effectively notifies immigration (through your next visa renewal) that freelancing is your main activity — and that can trigger questions your taxes cannot answer.

For work-status holders on the boundary, the Freelance Protection Act (in force since November 2024) does not change visa rules, but it does change how your clients must treat you.

Step 4: Blue return vs white return — and the deadline you may have already missed

Japan's income tax lets sole proprietors choose between white return (白色申告) — simple, no prior approval — and blue return (青色申告) — more bookkeeping, big deductions.

Blue return benefit	White return equivalent
¥650,000 special deduction (with e-Tax or certified digital books)	None
¥550,000 deduction (paper filing)	None
¥100,000 deduction (simple bookkeeping)	None
Carry forward losses for 3 years	Cannot carry forward
Pay family employees as deductible expense	Very limited

The critical catch: To use blue return for your 2025 income (filing in 2026), you needed to file the 青色申告承認申請書 by March 15, 2025 — or within two months of starting your business if you launched mid-year. If you missed that window, you file white this year. File the 承認申請書 by March 15, 2026 to use blue return for 2026 income.

The ¥650,000 deduction is also conditional: you must (a) keep double-entry books, (b) attach both a profit-and-loss statement and a balance sheet, and (c) either submit via e-Tax or maintain your books electronically under the 電子帳簿保存法 (filing the required 届出書 in advance). Paper filers without electronic books max out at ¥550,000.

Step 5: The 10.21% you may not know you lost

If you bill a Japanese company for writing, design, translation, interpretation, lecturing, or consulting (the services listed in Income Tax Act Article 204), they are legally required to withhold 10.21% of each invoice and remit it to the tax office. Rate rises to 20.42% on the portion of any single payment exceeding ¥1,000,000.

You get this money back — or at least credited toward your tax bill — only if you file a kakutei shinkoku. Enter:

• Total withheld amount on 第一表: 所得税及び復興特別所得税の源泉徴収税額
• Each payer, project, and amount on 第二表: 所得の内訳

Clients should send you a 支払調書 by late January. If yours does not arrive or contains errors, see our missing withholding slip guide. For e-Tax filers, attaching the 支払調書 is not required, but keep it for seven years.

Step 6: The invoice system — register or stay exempt?

Since October 2023, only registered invoice-issuing businesses (適格請求書発行事業者) can give clients proper qualified invoices that pass through full consumption-tax deduction. If you are not registered, your B2B clients cannot fully deduct your fee from their own consumption tax — which usually means they will either push your price down or stop using you.

If your taxable sales are...	Your choice
Under ¥10 million AND all clients are consumers or small businesses	Stay exempt (免税事業者). Keep the consumption-tax portion as income.
Under ¥10 million but most clients are companies	Register — or accept gradual price pressure. Use 2-wari特例 to soften the tax blow.
Over ¥10 million in any base period	You are automatically a taxable enterprise — register immediately.

The 2-wari特例 (two-tenths transition measure) lets former tax-exempt freelancers who registered as invoice-issuers pay consumption tax at just 20% of the received amount, instead of doing full purchase-credit accounting. It applies to taxable periods including October 1, 2023 through September 30, 2026. For individual filers, whose taxable period is the calendar year, this covers the 2025 and 2026 returns in full (because the 2026 calendar year includes September 30, 2026) — making the 2026 return the final one eligible. After that, you either switch to the simplified tax calculation (簡易課税) or do full accounting.

Step 7: Social insurance — the hidden second bill

Losing your company's shakai hoken (社会保険) when you go freelance matters more than the tax itself. Within 14 days of leaving employment, register at your ward office for:

• 国民健康保険 (National Health Insurance) — premium calculated from last year's income, so your first freelance year may still reflect your old salary
• 国民年金 (National Pension) — flat ¥17,510 per month in fiscal 2025 (¥210,120 per year)

You may also keep your old company's health insurance for up to two years via 任意継続, but you pay 100% yourself (the employer portion goes away). Running the numbers both ways is worth 30 minutes with a spreadsheet.

National Health Insurance premiums feed directly off your freelance income, so the expenses you deduct on your tax return also reduce next year's health insurance bill. Every receipt matters twice.

Step 8: What changed for 2025 income (令和7年分)

The 2025 tax reform dropped the biggest basic-deduction overhaul in years, and it applies to the return you are filing now:

Your total income	Basic deduction (was ¥480,000)
Up to ¥1.32 million	¥950,000
¥1.32M – ¥3.36M	¥880,000 (phasing to ¥580,000 from 2027)
¥3.36M – ¥4.89M	¥680,000
¥4.89M – ¥6.55M	¥630,000
¥6.55M – ¥23.5M	¥580,000 (permanent)

If you had modest freelance income in 2025 — say ¥1.5 million in profit — your basic deduction alone may be ¥880,000. Add the ¥650,000 blue-return deduction and your taxable income drops to zero. The form still has to go in, but the tax owed often will not.

Step 9: Deductible expenses — what counts, what does not

Expenses reduce your business income dollar for dollar. The general rule: an expense is deductible if it is directly related to generating your business income, and you have documentation. Common freelance expenses:

• Home office portion (家事按分): Rent, utilities, internet, and phone — deductible at a reasonable business-use ratio. Use floor area (% of home used for work) or hours of use. Write down your method and keep floor plans; this is the first thing a tax audit will ask about.
• Equipment: PC, monitor, chair, camera — deduct in full if under ¥100,000; depreciate over useful life if higher. Blue-return sole proprietors can use the ¥300,000 small-amount special rule (少額減価償却資産の特例), capped at ¥3 million per year in aggregate and currently scheduled to sunset on March 31, 2026 unless extended.
• Software and subscriptions: Adobe, Notion, ChatGPT Plus, etc. — 100% deductible if used for work.
• Travel: Train fares, taxi, flights for client meetings. Keep IC card logs and boarding passes.
• Meals with clients: Deductible as 接待交際費. Record date, attendees, purpose. Solo meals are not deductible.
• Books, training, conferences: Deductible as 新聞図書費 / 研修費.
• Professional fees: 税理士, 行政書士, and accounting software all deductible.

Everything you cannot prove with a receipt, an invoice, or a bank record is not deductible — no matter how sure you are that you spent it.

Step 10: Timeline and filing checklist

Date	What to do
Late January 2026	Clients send 支払調書 for 2025 payments
February 16, 2026	Kakutei shinkoku filing window opens
March 16, 2026	Filing deadline (and income tax payment deadline)
March 15, 2026	Deadline to submit 青色申告承認申請書 for 2026 income
March 31, 2026	Consumption tax return deadline for registered invoice-issuers
April 23, 2026	Auto-debit date for tax payment (if you enrolled in 振替納税)
June 2026	Your 2026 住民税 bill arrives, based on your 2025 income

What to gather before you sit down

• Every 支払調書 received
• Annual totals of bank deposits from clients (cross-check against 支払調書)
• Expense receipts, sorted by category
• Home rent / utility bills with your business-use ratio calculation
• National Health Insurance / National Pension payment records
• Life and earthquake insurance 控除証明書
• iDeCo / NISA records if applicable
• Your My Number card (or notification slip + photo ID)
• Bank details for any refund

If you file via NTA's online preparation tool, it walks you through field by field. The form is bilingual in parts, but submission is Japanese-only. Google Lens handles most of what the form does not translate.

When to pay a tax accountant

A 税理士 (zeirishi, certified tax accountant) charges roughly ¥50,000–¥150,000 to prepare an individual freelance return. Worth it if:

• You had foreign-source income or foreign assets over ¥50 million
• You are invoice-registered and mixing consumption tax categories
• You switched to or from non-resident status mid-year
• You want to set up a company (MK / 合同会社 / 株式会社) next year
• Your Japanese is not yet strong enough to read audit correspondence

What about the 183-day rule?

A common misconception: that Japan taxes you only if you spend more than 183 days here. That rule exists in some tax treaties for short-term visitors, but Japan's domestic residency test is different. You are a resident taxpayer if you have your 住所 (domicile) in Japan — judged by where your life is centered: home, family, job, assets. A freelancer with a Japanese apartment, a resident card, and clients here is a resident, regardless of how many days they traveled.

Foreign-national residents who have lived in Japan ≤5 years out of the past 10 are non-permanent residents (非永住者). You pay tax on all Japan-source income plus any foreign-source income that you remit to Japan. From year six onward, you are a full resident and taxed on worldwide income.

The bottom line

Most foreign freelancers owe less than they expect this year thanks to the basic-deduction hike. The real costs are not the tax itself — they are the three decisions around it: did you file your 開業届 and blue-return application in time, did you register for the invoice system, and does your visa actually allow what you are doing?

If you started freelancing mid-2025, you still have windows open. File the 開業届 retroactively. Submit the 青色申告承認申請書 by March 15, 2026 for next year's deduction. Decide on invoice registration before your next big B2B client asks. And if your visa is on the conditional list, talk to an immigration lawyer before your next renewal — the tax office and immigration do not share data, but your tax filing becomes part of your paper trail forever.
