Freelance vs. employee in Japan: what "gyomu itaku" really changes about your taxes
A question that comes up a lot: someone's current job is switching them — or they're considering switching themselves — from a regular employee contract to a "gyomu itaku" (業務委託) contract. It sounds like a small paperwork difference. Tax-wise, it isn't.
正社員から業務委託への切り替えは、書類上は小さな違いに見えても、税金の扱いは大きく変わります。
The core difference
As a regular employee, your company withholds income tax and residence tax from your paycheck automatically (源泉徴収) and handles most of the paperwork for you. As gyomu itaku, you're not an employee — you're a contractor. Nothing is withheld from what you're paid. That means the responsibility to calculate, declare, and pay your own tax shifts entirely onto you, through an annual tax return (確定申告).
Why this catches people off guard
The money hitting your bank account looks the same either way — sometimes even bigger, since nothing's been deducted yet. That's exactly the trap: it's easy to treat the full amount as spendable income, then find out at filing time that a real tax bill is due on money that's already been spent.
If you move to gyomu itaku, set aside a portion of every payment — many freelancers use somewhere around 20–30% as a rough placeholder — in a separate account, and treat it as already spent. Adjust once you actually know your real tax bracket and expenses.
There's an upside too
Filing your own return also means you can claim legitimate business expenses against your income — something employees generally can't do. And having a properly filed 確定申告 with clear, consistent numbers is exactly the kind of documentation banks want to see later if you ever apply for a loan. The tradeoff is real, but it runs both directions.
