Should You Hire a Tax Accountant (税理士) in Japan?

How Much Does a Zeirishi Cost?

Fees vary widely based on the scope of work, your income level, and location. Here are typical ranges:

Factors Affecting Price

• Revenue level: Higher revenue generally means higher fees, as the return is more complex and the accountant takes on more responsibility.
• Number of income sources: Multiple income types (business, real estate, stocks, foreign income) increase complexity.
• Record quality: If you hand over a box of receipts vs clean bookkeeping data, expect to pay more for the former.
• Location: Tokyo accountants tend to charge 10–20% more than those in smaller cities.
• English support: Bilingual accountants often charge a premium (¥50,000–100,000+ more) due to limited supply and higher demand.

What a Zeirishi Handles

A good tax accountant provides services beyond just filing your return:

• Tax return preparation and filing: They prepare your income tax return (確定申告書), consumption tax return if applicable, and any required schedules. They file it via e-Tax on your behalf.
• Bookkeeping review: They review your books for errors, ensure expenses are properly categorized, and verify compliance with Blue Return requirements.
• Tax planning and optimization: They advise on strategies to reduce your tax burden — timing of expenses, optimal deductions, salary optimization for corporations, and whether to elect simplified consumption tax.
• Audit representation (税務調査立会): If the NTA audits you, your zeirishi can represent you at the audit, respond to inquiries, and negotiate on your behalf. This alone can be worth the annual fee.
• Year-end adjustment (年末調整): For companies with employees, the accountant handles the year-end tax adjustment process.
• Business structure advice: They can advise on whether to incorporate, which company structure to choose, and optimal timing.

What You Still Need to Do Yourself

Even with a zeirishi, you remain responsible for:

• Collecting and organizing receipts: The accountant works with what you provide. Missing receipts mean missed deductions.
• Daily bookkeeping: Unless you pay for bookkeeping services, you should record transactions regularly in accounting software.
• Communicating changes: Inform your accountant about major events — new income sources, marriage, home purchase, children, leaving Japan.
• Making tax payments on time: The accountant files the return, but you are responsible for paying the tax by the deadline.
• Keeping records: You must retain records for 5–7 years even if your accountant has copies.

When Self-Filing Makes Sense

You can probably handle your own taxes if:

• You have simple employment income from one employer and your company handles year-end adjustment. You only need to file if claiming additional deductions (medical expenses, furusato nozei without one-stop, etc.).
• You have low freelance income (under ¥3,000,000–4,000,000) with straightforward expenses and no consumption tax obligation.
• You are comfortable using accounting software in Japanese or English and can maintain double-entry bookkeeping.
• You have a single income source with few deductions.
• You enjoy learning about taxes and are willing to invest time in understanding the system.

When You Should Definitely Hire a Zeirishi

Professional help becomes strongly recommended when:

• Multiple income sources: Business income plus employment, real estate, stock trading, foreign income, or cryptocurrency gains.
• High revenue: Business revenue exceeding ¥10,000,000, especially if you have consumption tax obligations.
• Corporate tax returns: Company tax filing is substantially more complex than individual returns and mistakes are costly.
• Complex deductions: Home office ratios, mixed-use assets, depreciation schedules, international transactions.
• Tax audit: If you receive an audit notification (税務調査の通知), having professional representation is critical.
• Life events: Incorporating a business, buying property, receiving inheritance, or leaving Japan all have complex tax implications.
• Limited Japanese ability: If you cannot read the tax forms and NTA guidance documents, the risk of errors is high.

How to Find a Good Tax Accountant

Where to Search

• Japan Federation of Certified Public Tax Accountants (日本税理士会連合会): The official directory at zeirishikensaku.jp lets you search by area and specialty.
• Matching services: Platforms like 税理士ドットコム and freee’s accountant directory connect you with vetted professionals.
• Referrals: Ask fellow freelancers or business owners. Personal recommendations are often the most reliable.
• English-speaking accountants: Search for “English speaking zeirishi” or “英語対応 税理士” in your area. Major cities like Tokyo, Osaka, and Fukuoka have more bilingual options.

What to Look For

• Experience with your industry or situation (freelancer, corporate, foreign national)
• Clear pricing — get a written quote before engaging
• Responsiveness — a good accountant returns calls/emails promptly
• Proactive advice — they should suggest optimizations, not just file what you give them
• Compatibility with your accounting software
• Willingness to explain things — you should understand what is being filed on your behalf

Red Flags

• Refuses to provide a written fee estimate
• Suggests aggressive tax positions without explaining the risk
• Is difficult to reach, especially during filing season
• Does not use any accounting software (all manual)
• Cannot explain their strategies in terms you understand
