Somewhere between the invoice system rollout and every accounting app suddenly adding an “AI receipt scanning” button, a lot of freelancers in Japan absorbed a vague sense that “digital receipts are now mandatory” — without ever getting a straight answer on what that actually means day to day.

TL;DR

  • 電子帳簿保存法 (the Electronic Bookkeeping Law) is actually made up of several rules depending on the type of record. This post focuses on the electronic transaction data preservation rule: receipts and invoices you receive digitally — email PDFs, online store receipts, chat-app invoices — must be stored as electronic data, not printed out and filed on paper as your only record. (The law also has separate rules for electronic books/documents you create yourself and for scanner storage of paper documents.)
  • Paper receipts (a physical shop receipt, a taxi stub) can still be kept as paper, and photographing them for electronic storage is optional. But if you then discard the paper original, that scan has to meet separate scanner-storage requirements (resolution, a timestamp or accepted alternative, a correction/deletion history, searchability).
  • Digitally stored records generally need to be searchable by date, amount, and counterparty (issuer/payee name) — though some smaller filers qualify for exemptions — and their authenticity has to be protected, which can be done several ways, not just with a timestamp.
  • This is a separate requirement from the invoice system (インボイス制度), which governs the ledger and qualified-invoice documentation needed for a consumption-tax input credit — you generally need to satisfy both, though transitional measures currently soften the invoice-system side.
  • Retention periods for blue-return (青色申告) filers depend on the type of document — most fall in the 5–7 year range. See the breakdown below.

What Does the E-Bookkeeping Law Actually Cover?

電子帳簿保存法 is actually three separate sets of rules: electronic books/documents you create yourself, scanner storage of paper documents, and electronic transaction data preservation. This post focuses on that third piece, since it’s the one that governs how freelancers handle everyday digitally-received receipts and invoices.

Within that scope, the law governs how you store accounting records that originate digitally, not whether you’re allowed to keep paper at all. If a receipt or invoice arrives as an email attachment, a PDF download from an online store, or an image sent over a chat app, the law says you must preserve that transaction information as electronic data — printing it out and treating the printout as your only record is generally not sufficient for those digitally-received documents. That doesn’t mean the file has to stay exactly as received: a reasonable format conversion — say, a Word or Excel invoice saved as PDF — is fine as long as the transaction content doesn’t change. And if you receive an identical document in both paper and digital form and treat the paper copy as your official original, paper-only storage can be enough under the paper-original rule.

This trips people up because it sounds like it’s asking for a wholesale switch to digital bookkeeping. It isn’t. A taxi receipt handed to you on paper, or a printed receipt from a corner store, can still be kept as paper. You’re also allowed to photograph paper receipts and store them electronically if you’d rather go fully digital — but if you then throw away the paper original, that photo has to meet the separate scanner-storage requirements (roughly: 200dpi or better resolution, color where required, a timestamp or an accepted alternative, a record of any corrections or deletions, and searchability). A smartphone photo counts as scanner storage too, as long as it meets those conditions. Keeping the paper alongside a photo for convenience doesn’t trigger any of this — the obligation only kicks in for records that were digital from the start, or where you’ve chosen to make the digital copy your sole official record.

What Makes a Digital Record Compliant?

A compliant digital record has to be searchable and its authenticity protected — not just saved somewhere — but the requirements are more flexible than they first appear, and some filers qualify for exemptions.

On searchability: in principle, tax authorities expect you to be able to pull up any given receipt by three fields — date, amount, and counterparty (who issued it or who you paid). But if you’re able to respond to a tax office request to download your data, you don’t need range-search or combined-condition search capability. And if your base-period sales are ¥50 million or less, or you can present or submit printed records organized by date and counterparty on request, you may not need to maintain a search function at all. A folder full of randomly-named PDFs is still a bad habit — it slows down and adds risk to producing records on request — but whether it’s actually a compliance failure depends on which of these exemptions apply to you.

On authenticity, there’s no single mandated tool. You can satisfy this requirement in any of four ways: (1) receive the record with a timestamp already attached, (2) attach a timestamp yourself promptly after receiving it, (3) use a system that either logs any corrections/deletions or doesn’t allow them at all, or (4) adopt and actually follow a written correction/deletion-prevention policy for handling these records. A purpose-built tool can make this easier to manage day to day, but a documented process on generic storage can satisfy it too — see the FAQ below.

How Is This Different From the Invoice System?

The invoice system and the e-bookkeeping law solve two different problems, and both generally apply at once. The invoice system (インボイス制度, in effect since October 2023) requires, in principle, that you keep a qualifying ledger and a “qualified invoice” (適格請求書) — one that includes the issuer’s registration number among other required details — in order to claim the consumption-tax input credit. The registration number is one required element of a qualified invoice, not the sole determinant of whether the credit is available: transitional measures currently allow a partial credit on purchases from businesses that aren’t registered issuers — 80% through September 30, 2026, then 50% from October 1, 2026 through September 30, 2029 — and other exceptions apply in specific cases. The e-bookkeeping law, meanwhile, is about how that receipt is stored once you have it, regardless of what it says. A perfectly compliant invoice-system receipt that you print and file in a binder can still put you offside on the storage side if it originally arrived digitally.

In practice this means every digitally-received receipt needs attention on two separate fronts: does it carry the right information for tax-credit purposes, and is it stored in a way that’s searchable and authenticity-protected. Falling short on either one can be a real gap, not just a minor paperwork nitpick.

How Long Do You Need to Keep These Records?

For sole proprietors filing blue returns (青色申告), the retention period depends on the type of document rather than one flat number:

  • Books and settlement-related documents (general ledger, balance sheet, P&L, etc.): 7 years.
  • Cash and deposit transaction documents — the category most receipts fall into: generally 7 years, but 5 years if your combined business and real-estate income two years prior was ¥3 million or less.
  • Other documents — invoices, quotes, contracts, delivery notes, and similar: 5 years.
  • Records needed for the consumption-tax input credit — required invoices/documents, plus copies or electronic records of qualified invoices issued by a registered business: 7 years.

For most freelancers and small operators, that lands somewhere in the 5–7 year range depending on the document type — it’s worth knowing which bucket your records fall into rather than assuming a single number. The retention clock doesn’t reset based on whether a record originated on paper or digitally; only the storage method — and the document category — changes what’s required.

Where This Actually Gets Painful in Practice

The real pain point isn’t the rule itself — it’s that a typical freelancer’s receipts arrive in a half-dozen different formats: a PDF invoice from a client, a screenshot of a payment confirmation, an email receipt from an online tool subscription, and a paper receipt from a supply run, all mixed together with no consistent naming or filing habit.

To be clear, generic cloud storage can satisfy the requirements above if you pair it with a consistent naming convention, an index list, and a written correction/deletion policy — the law doesn’t mandate specialized software. But manually extracting date, payee, amount, and tax rate from each receipt and keeping that structure consistent month after month is exactly the kind of repetitive, error-prone task that’s easy to fall behind on. A purpose-built tool makes that extraction and search management easier to keep on top of — which is the gap we built Reshito to close: it scans mixed-format receipts and pulls out the fields you need into a searchable ledger, so you’re not reconstructing three months of records the week before filing.

FAQ

Q: Do I need to scan and digitize all my paper receipts?

No. Paper receipts you receive as paper can stay as paper. Digitizing them is optional — useful if you want everything in one searchable system, but not a legal requirement under the e-bookkeeping law. If you do digitize them and then discard the paper originals, though, the scan needs to meet the scanner-storage requirements (resolution, a timestamp or accepted alternative, searchability, and so on).

Q: What happens if a digital receipt is stored as a random file in cloud storage without a way to search by counterparty?

It depends on your situation. In principle, that’s a searchability gap — the law expects you to be able to retrieve records by date, amount, and counterparty on demand, not just have the file backed up somewhere. But if you can respond to a tax office request to download your data, you’re exempt from needing range- or combined-condition search; and if your base-period sales are ¥50 million or less, or you can produce records organized by date and counterparty on request, you may not need a search function at all. Outside those exemptions, a consistent file-naming convention or a simple index list (even a spreadsheet) alongside your files can also satisfy the requirement without special software.

Q: Does this apply to incorporated companies too, or just sole proprietors?

The e-bookkeeping law applies to businesses generally, including corporations, though this post focuses on the sole-proprietor/freelancer case. The retention periods cited here (5–7 years depending on document type) assume a blue-return filer; corporate retention rules can differ, so check your specific filing category.
