Before October 2023, managing receipts as a Japanese sole proprietor was already annoying. After the invoice system (インボイス制度) kicked in, it became genuinely complicated. Most freelancers I talk to are still figuring out exactly what they need to keep — and why the rules changed in ways that aren’t obvious from the headlines.

This post is partly useful background on Japanese receipt compliance, and partly an honest look at Reshito (https://reshito.jp), the AI receipt scanner we built to tackle this specific problem.

TL;DR

  • Since October 2023, a qualified invoice showing the issuer’s registration number is generally required for the full consumption-tax input credit; for purchases from exempt or unregistered suppliers, transitional relief may allow partial credits through a phased reduction ending 2031-09-30
  • The e-bookkeeping law (電子帳簿保存法) requires digitally-received receipts to be stored digitally with search functions by date, amount, and counterparty, plus tamper-prevention measures such as a timestamp or an approved alternative
  • Paper receipts can be stored digitally under the scanner preservation rules, but requirements go beyond timestamping: resolution, color depth, linkage to books, and more
  • For individual blue-return filers (青色申告), receipts and cash/deposit documents are generally kept 7 years (or 5 years in some cases); white-return filers keep receipts for 5 years; the period is counted from the day after March 15 of the following year
  • Reshito photographs receipts and uses AI to extract date, payee, amount, and tax rate, then categorizes expenses ready for tax filing

What Changed for Japanese Freelancers After October 2023?

The invoice system fundamentally changed what a valid receipt looks like for tax purposes. Before, a receipt showing the date, amount, and vendor name was enough for an expense deduction. Now, to claim the full consumption-tax input credit (仕入税額控除), a qualified invoice must include the vendor’s invoice registration number (適格請求書発行事業者の登録番号).

A qualified invoice is generally required for the full input tax credit. For purchases from exempt or unregistered suppliers, transitional relief may allow partial credits: 80% credit until 2026-09-30, 70% from 2026-10-01 to 2028-09-30, 50% from 2028-10-01 to 2030-09-30, and 30% from 2030-10-01 to 2031-09-30, provided the required books and invoices are kept.

This doesn’t mean every receipt without a number is worthless — you can still deduct the underlying expense. But for consumption-tax registered businesses, missing registration numbers mean leaving tax credits on the table. For many freelancers moving toward consumption-tax registration themselves, this has become a real paperwork problem, because suddenly the quality of the receipt matters, not just the fact that you have one.

Separately, the Electronic Books Preservation Act (電子帳簿保存法) tightened requirements around digital records, with revised rules effectively mandatory for electronic transaction data from 2024-01-01. If a receipt arrives electronically — an email PDF, a download from a vendor portal — it must be stored digitally, not printed and filed in a folder. The digital records must include visibility and search functions by date, amount, and counterparty, plus tamper-prevention measures such as a timestamp, a revision-history or undeletable system, or an anti-deletion office rule. Taxpayers with base-period sales of JPY 50 million or less may be exempt from the search-function requirement if they can respond to download requests on demand. The search-and-tamper-prevention requirements are what most people miss.

Do Japanese Freelancers Still Need to Keep Paper Receipts?

Paper receipts remain valid, but the rules for digitizing them under the scanner preservation rules are specific. Paper receipts may be stored via scanner or smartphone, but important documents such as receipts generally require timely input, resolution of 200 dpi or higher, 24-bit color, a timestamp or an accepted alternative, version control, linkage to the books, display and output readiness, system documentation, and search functions. A photograph dropped into a folder does not satisfy these requirements.

For blue-return filers (青色申告 — the filing status that unlocks the 650,000 yen special deduction), the retention requirements vary by document type (see the FAQ below). Either way, that means keeping a mix of formats: handwritten izakaya slips, printed convenience-store receipts, PDF invoices from overseas SaaS tools, supplier invoices in every conceivable layout.

How Would You Manage This Without a Tool?

You can absolutely handle this manually. The workflow I’d suggest:

  1. Photograph every paper receipt immediately — batching them creates a pile that never gets processed
  2. Keep a running spreadsheet with columns for date, vendor/payee, amount, consumption-tax amount, tax rate (8% vs 10%), and registration number if visible
  3. Name your digital files consistently — something like YYYYMMDD_VendorName_Amount.jpg makes searching possible
  4. File PDFs and email receipts the moment they arrive, in a folder structure your accountant can navigate
  5. Reconcile against bank and credit card statements at month end to catch anything missed

This works. It’s tedious, and it breaks down when life gets busy and the pile grows. But if you’re handling 20–30 receipts a month and want full control over your own system, a spreadsheet and a consistent naming convention is a legitimate approach.

What Is Reshito, and Why Did We Build It?

Reshito (https://reshito.jp) is the AI receipt scanner we built for Japanese freelancers and sole proprietors. The core idea is simple: photograph a receipt, and the AI extracts the date, payee, amount, and tax rate, then categorizes the expense (経費) in a format ready for tax filing and the invoice system.

We built it because the manual workflow above works until it doesn’t. The point of failure is almost always the extraction step: reading a crumpled konbini receipt, a handwritten supplier slip, or a PDF invoice and pulling out the right numbers accurately. That’s where errors creep in and where the pile-up starts.

The tax-rate distinction matters more than people realize. Japan’s combined consumption-tax rates are 10% standard and 8% reduced. The 8% reduced rate applies mainly to food and non-alcoholic beverages excluding restaurant meals and catering, and to certain subscription newspapers. Misclassifying the rate on even a handful of receipts can create discrepancies in your consumption-tax return that attract questions.

Where Does Reshito Fit — and Where Does It Not?

Reshito fits well if you’re a freelancer, sole proprietor, or small business owner dealing with a mix of Japanese receipt formats: konbini receipts, supplier invoices, handwritten slips, PDF downloads. The AI extraction handles format variation — the thing that makes manual entry slow.

Where it doesn’t substitute: Reshito is a bookkeeping and receipt management tool, not an accountant. It won’t file your tax return, advise on whether a specific expense qualifies as 経費, or tell you whether you should register for the invoice system. For those questions, you still need a tax professional. The tool helps you keep organized records so that conversation is faster and more accurate.

If you’re handling very high receipt volumes, or have complex situations involving multiple business entities, the right solution is probably a full accounting system with a dedicated bookkeeper.

FAQ

Q: Does every receipt need an invoice registration number now?

Not every receipt — you can still deduct the underlying expense without one. But to claim the full consumption-tax input credit (仕入税額控除) on a specific purchase, a qualified invoice showing the vendor’s registration number is generally required. For purchases from exempt or unregistered suppliers, transitional relief may still allow partial credits: 80% until 2026-09-30, 70% from 2026-10-01 to 2028-09-30, 50% from 2028-10-01 to 2030-09-30, and 30% from 2030-10-01 to 2031-09-30, provided the required books and invoices are kept.

Q: Can I just photograph receipts with my phone and call it compliant?

A photograph is a valid digitization method for paper receipts under the scanner preservation rules of the e-bookkeeping law, but photographing alone is not sufficient. Paper receipts stored electronically must generally meet requirements including timely input, 200 dpi or higher resolution, 24-bit color, a timestamp or an accepted alternative, version control, and search functions. Storing photos in a phone camera roll does not satisfy these requirements. A tool that organizes extracted receipt data into a searchable, compliant ledger can help meet them.

Q: How long do Japanese freelancers need to keep receipts?

For individual blue-return filers (青色申告), books and closing documents are generally kept for 7 years. Cash and deposit transaction documents, including receipts, are kept for 7 years — or 5 years if the previous-second-year business or real-estate income is JPY 3 million or less. Other documents such as invoices and contracts are generally kept for 5 years. Consumption-tax invoices retained for input credits are generally kept for 7 years. For white-return filers (白色申告), statutory books are kept for 7 years, and other documents including receipts are kept for 5 years. In both cases, the retention period is counted from the day after March 15 of the following year, not from the actual filing date or the date of the receipt.
