How to bill clients, why some payments arrive short (withholding at source), and how to keep cash flow steady.
Issue a clear invoice (with your T-number if registered), expect certain professional fees to arrive with about 10% withheld at source, and credit that withholding when you file so it is not double-counted.
A good invoice removes friction and gets you paid faster: identify yourself and the client, describe the work, show the amount and consumption tax, state the due date and bank details, and — if you have registered for the invoice system — include your T-number so business clients can claim their input credit. Invoicing tools such as MakeLeaps, Misoca, and board generate compliant invoices, track paid/unpaid status, and store copies for you; some are English-friendly, which helps when billing overseas clients.
Keep your own copy and reconcile it against the deposit. If you are registered for consumption tax, the qualified-invoice format has specific required fields, so use a tool or template that already meets them rather than a plain document.
For certain categories of fees paid to individuals — writing, design, translation, lectures, and some professional services — the paying company must withhold income tax at source, roughly 10.21%, and remit it to the tax office on your behalf. So a ¥100,000 fee can land as about ¥89,790. This is not a loss: it is a prepayment of your income tax. When you file, you total the tax already withheld (shown on the client’s payment record) and subtract it from what you owe, often producing a refund.
Two practical points follow. Track withholding per client so your return credits all of it — leaving it out means paying twice. And plan cash flow around it: the timing of invoices, withholding, consumption tax, and late payers all move real money, so keep a buffer and, if slow payers threaten your runway, services that advance invoice cash exist (at a cost) for freelancers.

For certain fees paid to individuals — writing, design, translation, lectures, and some professional services — the paying company must withhold income tax at source (about 10.21%) and remit it for you, so the deposit arrives smaller than the invoice. This is a prepayment, not a loss: when you file, you total the tax already withheld from each client’s payment record and credit it against what you owe, which often produces a refund. Track withholding per client so you claim all of it and don’t effectively pay twice.
It depends on your clients. Registering gives you a T-number so business clients can claim consumption-tax input credits on what they pay you — but it also makes you a consumption-tax payer, adding cost and paperwork. If your clients are consumers or tax-exempt small businesses, registering may add cost for no benefit. If your clients are companies that demand qualified invoices, not registering can cost you work. Weigh your client base; a transitional credit for buyers from unregistered suppliers is stepping down over time.
