Non-resident companies setting up to import into Japan routinely assume that appointing an Attorney for Customs Procedures (税関事務管理人, ACP) covers their entire non-resident compliance obligation. It does not. A separate appointment, the Tax Representative (納税管理人), is required under Japan's consumption tax framework, and it answers to a different government agency with a different scope of authority entirely. Confusing the two, or assuming one substitutes for the other, is one of the most common structural errors non-resident importers make, and it has direct financial consequences. This post sets out what each appointment actually authorizes, why most non-resident importers need both rather than either, and what happens when only one is in place.
Two Appointments, Two Agencies, Two Legal Bases
The confusion is understandable because both roles are filled by a Japan-resident party on behalf of the same non-resident company, and in practice the same provider often holds both appointments simultaneously. But "same provider" is not "same appointment." Each role rests on separate legal authority and answers to a separate government body.
The ACP appointment (税関事務管理人) is created under the Customs Act (関税法), Article 95. It is filed with Japan Customs and covers customs clearance procedures only.
The Tax Representative appointment (納税管理人) is created under Japan's national tax framework and is required specifically for consumption tax (消費税, JCT) matters under the Consumption Tax Act (消費税法). It is filed with the National Tax Agency (国税庁, NTA) and covers the non-resident's standing as a taxpayer, not its standing as an importer.
These are non-overlapping legal appointments. Neither notification substitutes for the other, and filing one does not put the other on file. A non-resident company that has only completed an ACP notification has not, by that fact alone, satisfied its consumption tax representation obligation, and vice versa.
What the ACP Appointment Actually Authorizes
Under the Customs Act (関税法) Article 95, a non-resident entity that wants to be named as the legal importer on a Japan import declaration (輸入申告) must have a Japan-resident agent standing behind that declaration. The ACP is that agent. The non-resident remains the importer of record and retains title to the goods; the ACP is the statutory point of contact for Japan Customs, accepts service of customs notices, and coordinates the clearance process.
The ACP's authority stops at the customs procedure boundary. It does not extend to tax registration, tax filing, or any interaction with the National Tax Agency. A company that has only an ACP notification on file has a valid path to clear goods through Japan Customs and nothing more.
What the Tax Representative Appointment Actually Authorizes
The Tax Representative (納税管理人) is the non-resident's designated domestic contact for national tax matters, specifically consumption tax obligations arising from the non-resident's activity in Japan. This appointment is what allows the non-resident to register as a Qualified Invoice Issuer (適格請求書発行事業者) under the Qualified Invoice System (インボイス制度) and, subsequently, to file consumption tax returns with the National Tax Agency.
The Tax Representative's authority does not touch customs clearance at all. A Tax Representative appointment on file with the NTA, with no ACP notification filed with Japan Customs, does not authorize the non-resident to be named as importer on any declaration. The return itself is filed by a Licensed Tax Accountant (税理士) under the Licensed Tax Accountant Act (税理士法), a function reserved to that licensed profession; the Tax Representative role and the return-filing function are related but distinct.
Why Most Non-Resident Importers Need Both
For a recurring, revenue-generating import program, the two appointments serve two halves of a single outcome, and neither half works alone.
(a) Clearing goods through Japan Customs as a non-resident importer requires the ACP appointment.
(b) Recovering the import consumption tax paid at clearance, so it does not become a permanent cost, requires the non-resident to be a registered Qualified Invoice Issuer, which in turn requires the Tax Representative appointment.
A non-resident importer who wants both a working clearance path and a recoverable JCT position needs both appointments in place, not one or the other. This is not an either/or decision the way choosing between commercial structures might be; it is closer to needing both a driver's license and vehicle registration to legally operate a car. One authorizes the activity, the other authorizes the tax position that activity generates. For the full sequencing of ACP, Tax Representative, and Qualified Invoice System registration before a first shipment, see our setup guide linked below.
What Happens If Only One Is In Place
ACP in Place, No Tax Representative
Goods clear customs normally. The ACP notification is valid and Japan Customs has no basis to refuse the declaration on that ground. But the import consumption tax paid at clearance has no registration behind it to make it creditable. Without a Tax Representative appointment and the resulting Qualified Invoice System registration, the JCT paid on every shipment is a direct, non-recoverable cost. This does not correct itself retroactively once the Tax Representative is later appointed; JCT paid during the period without registration cannot be reclaimed after the fact.
Tax Representative in Place, No ACP
The non-resident may be a properly registered Qualified Invoice Issuer with the National Tax Agency, but that registration confers no authority to clear goods through Japan Customs as the named importer. Without a valid ACP notification on file, Japan Customs has no basis to process an import declaration naming the non-resident as importer, and clearance will stall or be refused. A tax registration cannot substitute for the customs-side representation the Customs Act requires.
Decision Summary: Which Role Does What
(a) Question: who reviews my import declaration and can hold up my goods at the port? Japan Customs, through the ACP appointment. The Tax Representative has no standing here.
(b) Question: who determines whether my import consumption tax comes back to me? The National Tax Agency, through the Tax Representative appointment and the resulting Qualified Invoice System registration. The ACP appointment has no bearing on this question by itself.
(c) Question: do I need one appointment or two? If the goal is only to clear customs with no expectation of recovering JCT, the ACP appointment alone technically permits clearance, at the cost of forfeiting every yen of import JCT paid. For any importer expecting recurring volume or a functioning JCT recovery path, both appointments are required, and neither is optional once revenue-generating imports begin.
Closing Point
The ACP and the Tax Representative are not competing options and not two labels for the same function. They are separate legal appointments, filed with separate government bodies, authorizing separate activities. Non-resident importers who treat the ACP notification as covering their full compliance picture typically discover the gap only when their first consumption tax filing comes due, and by then the tax on already-cleared shipments cannot be recovered. Structuring both appointments before the first shipment, not after, is the only way to avoid that outcome.
