This is one of those decisions where "just wait and see" can quietly cost you money — either in tax you didn't have to pay, or in clients you lost. Mio doesn't do vibes. Here's the trade-off, read from the Japanese-language NTA sources. This is general information, not tax advice — confirm your own situation with the NTA or a licensed tax accountant (税理士).
Under Japan's consumption tax rules, a business is generally exempt from the obligation to remit consumption tax for a taxable period if its taxable sales in the base period (基準期間, in principle two years earlier) were ¥10 million or less. Many freelancers and small sole proprietors sit under this line, so historically they charged clients but were not required to hand consumption tax to the tax office. (There are extra tests — e.g. a "specified period" test — so this is a simplification; verify your own status.)
On October 1, 2023, the qualified invoice-based method — the "Invoice System" (適格請求書等保存方式 / インボイス制度) — took effect. It did not abolish the ¥10M exemption. What it changed is the paperwork on the buyer's side: for a business client to claim input tax credit (仕入税額控除) on what it pays you, it generally needs to hold a qualified invoice. And a qualified invoice can only be issued by a registered qualified-invoice issuer — and only a taxable business can register. In short: tax-exempt = can't issue a qualified invoice.
That leaves a small freelancer with two broad paths, each with a cost:
Path A — register: You become a taxable business, can issue qualified invoices, and your clients keep their input tax credit. The cost: you lose the exemption and must file and remit consumption tax, plus do the extra bookkeeping.
Path B — stay exempt: You keep the exemption and skip consumption-tax filing. The risk: business clients who can't claim the credit on your invoices may ask you to lower your price, absorb the difference, or (in some cases) prefer registered suppliers. How real this pressure is depends heavily on who your clients are.
B2B freelancers — those invoicing companies (design, translation, dev, consulting, contractors) — are the most affected, because their clients care about the input tax credit. B2C / consumer-facing freelancers — selling to individual customers who don't claim input tax credit — are usually much less affected, since consumers don't file for the credit. If your customers are private individuals, the pressure to register is typically low.
To soften the blow, the NTA provides a transitional measure often called the "20% special rule" (2割特例). In broad terms, an eligible small business that became a registered qualified-invoice issuer because of the Invoice System (i.e. would otherwise have been tax-exempt) can calculate the consumption tax it owes as roughly 20% of the tax on its sales — instead of the full amount — during the covered periods. This is an easing measure, not a permanent regime.
Timing matters and it's time-limited. Per the NTA, the relief targets businesses that register as qualified-invoice issuers in the window running from October 1, 2023 through September 30, 2026 (Reiwa 5–Reiwa 8), applying to the taxable periods in that window. Because the exact eligible periods depend on when you register and your fiscal timing, and rules shift, do not rely on these dates for your own filing — check the current NTA pamphlet or ask a tax accountant.
| Your main clients | Do they need the input tax credit? | Usual lean (illustrative) |
|---|---|---|
| Businesses (B2B), taxable | Yes | Registering often makes sense — the 2割特例 can cushion the cost |
| Consumers (B2C, individuals) | No | Staying exempt is usually fine — little client pressure |
| Mixed, or unsure | Depends | Ask clients directly + confirm with a 税理士 before deciding |
Highly simplified. "Registering" has real filing, cash-flow, and bookkeeping consequences; the exemption tests (base period / specified period) and 2割特例 eligibility have conditions this table can't capture. Treat it as a starting point, not a rule.
Mostly consumer clients → the exemption is usually still worth keeping. Mostly business clients → registering (and using the 20% transitional rule while it lasts) is often the cleaner call. The "right" answer isn't about principle — it's about whether the people paying you need a qualified invoice. Get the numbers for your client mix, then confirm with the NTA or a tax accountant before you file anything.
