Moving Back to Japan: Updating Your Address with the IRS (Form 8822) and Appointing a Representative from Abroad (Form 2848)

Moving back to Japan rarely ends your relationship with the IRS. Many returnees still need to file Form 1040-NR, collect a refund, or respond to notices. If the IRS does not have your new address, notices go to the old one and deadlines pass unnoticed, and refund checks never arrive. Calling the IRS from Japan across a 13- or 14-hour time difference is not a realistic way to resolve problems either. This article explains how to update your address with Form 8822 and what to watch for, how to appoint a U.S. tax professional as your representative with Form 2848, when Form 8821 is the better tool, how to use the IRS online account from abroad, and the practicalities of mailing documents and receiving refunds from Japan. Rules are as of 2026.

Form 8822: Telling the IRS Where You Live

Individuals report a change of address on Form 8822. Businesses use Form 8822-B for changes to the address or responsible party associated with an EIN. The IRS also updates its records from the address on a filed return, but because months usually pass between a move and the next return, file Form 8822 as soon as the move is set. Processing takes about four to six weeks.

• Write your Japanese address in English with the city, prefecture, postal code, and the country name (Japan) in full. Do not abbreviate the country.
• If you filed jointly, include your spouse’s name and SSN. If you will file separately after the move, each spouse may need a separate form.
• Mail the form to the IRS address shown in the instructions, which depends on your old state of residence.
• State tax agencies must be notified separately. In states such as New York and California, where residency after a move is often questioned, a clearly documented move-out date and new address are important evidence if the state asks.

Should you use a relative’s U.S. address?

Some returnees keep a U.S. address on file to be sure notices arrive. Listing an address where you do not actually live can hurt you in a state residency dispute and can delay forwarding. The better approach is to report your real Japanese address and have a representative receive copies of notices through Form 2848 or Form 8821, as explained below.

Form 2848: Power of Attorney Before the IRS

Form 2848 (Power of Attorney and Declaration of Representative) authorizes a U.S. CPA, enrolled agent, or attorney to act for you before the IRS. The representative can call and write to the IRS, handle examinations and collection matters, sign agreements, and receive copies of notices. For a taxpayer in Japan, the ability of a representative to reach the IRS practitioner line during U.S. business hours is a major practical advantage.

• Specify the tax matters (for example, income tax), the forms (Form 1040, 1040-NR), and the years. Future years can be listed up to three years beyond the year you sign.
• Check the box if you want the representative to receive copies of notices and communications.
• The representative must be eligible to practice before the IRS and hold a CAF number. A Japanese zeirishi generally cannot serve unless he or she also holds a U.S. credential such as the EA.
• Submission options include the IRS online submission with electronic signatures, approval through the representative’s Tax Pro Account (which requires you to have an IRS online account), or fax and mail.
• A power of attorney remains in effect until revoked. To change representatives, file a new Form 2848 or submit the old one marked REVOKE.

Form 8821: Information Access Without Representation

Form 8821 (Tax Information Authorization) allows a designee to inspect and receive your IRS records, including transcripts and notices, but does not authorize them to negotiate on your behalf. It suits situations where a family member in the U.S. should be able to see what a notice says, or where an accounting firm monitors your account transcripts periodically. The third party designee box on Form 1040 is narrower still: it covers only simple questions about that year’s return and expires one year after the return’s due date, so it is not a substitute for ongoing representation.

Form	What it allows	Typical use
Form 8822	Updates the address in IRS records	Moving back to Japan, any relocation
Form 2848	Representative negotiates, signs documents, receives notices	Return preparation, audits, collection notices, tracking refunds
Form 8821	Designee views records and receives notices only	Letting family or a firm monitor your account
Third party designee (on Form 1040)	Simple questions about that return only	Checking processing status

Using the IRS Online Account, Paying, and Receiving Refunds from Abroad

• The IRS online account is accessible from overseas through the ID.me identity service and lets you view balances, retrieve transcripts, and make payments. Verification requires identity documents such as a passport and sometimes a video call.
• Payments: Direct Pay works if you keep a U.S. bank account. Otherwise, credit or debit card payments (with a processing fee) or an international wire transfer are available.
• Refunds: direct deposit is only possible to a U.S. bank account. A paper check can be mailed to a Japanese address, but it takes a long time to arrive and Japanese banks charge fees and take weeks to collect it. If you expect refunds after your move, keeping a U.S. account is worthwhile.
• IRS notices (CP notices and letters) are mailed to foreign addresses but may take several weeks to arrive. Because notices carry response deadlines, arranging for a representative to receive copies is valuable.

Mailing Documents from Japan

The IRS accepts mail sent through Japan Post, and a return bearing a foreign postal service’s postmark on or before the due date is treated as timely filed. Use a trackable service such as EMS and keep the postmark and tracking records. If you use one of the private delivery services the IRS designates (specific DHL, FedEx, and UPS services), send to the street address the IRS lists for those carriers, not to a P.O. box. Form 1040-NR can be filed electronically, which makes it much easier to confirm receipt.

Frequently Asked Questions

I found out that IRS notices went to my old U.S. address after I moved. What should I do?

File Form 8822 to update the address, then check the content and deadlines of the notices through your IRS online account or a representative. Even if a deadline has passed, responding promptly and explaining the circumstances can lead to penalty relief, such as first-time abatement.

Can my Japanese tax accountant deal with the IRS for me?

Only individuals authorized to practice before the IRS, such as U.S. CPAs, enrolled agents, and attorneys, can be named on Form 2848. A Japanese zeirishi who also holds the U.S. EA credential can serve. If you want your Japanese and U.S. filings handled together, choose a professional with credentials in both countries or a team of advisers who coordinate.

Do I also need to update my address with the Social Security Administration?

Yes. The IRS and the SSA are separate agencies. Update the SSA through a my Social Security online account or through the Federal Benefits Unit at the U.S. Embassy in Tokyo. This is especially important if you receive or expect to receive benefits.

Summary

Your communication channel with the IRS after moving to Japan rests on three forms: Form 8822 to record your Japanese address, Form 2848 to appoint a U.S. tax professional who can act for you and receive copies of notices, and, where appropriate, Form 8821 to let family or a firm view your records. The IRS online account works from abroad, and refunds are far simpler with a U.S. bank account. Setting up this structure before you leave is the most reliable way to avoid missed notices, blown deadlines, and unnecessary penalties after your return.
