The Reality of Government Impersonation Scams
Government impersonation scams exploit trust in authority and are among the most malicious forms of phone fraud. Scammers pose as police, tax officials, pension office staff, court officials, or immigration officers, using claims like "An arrest warrant has been issued," "You have unpaid taxes," or "You're owed a pension refund" to panic victims. Mass dialing using automated voice calls (robocalls), and the use of caller ID spoofing to display a government agency number on the recipient's screen, have both been confirmed.
Common Government Impersonation Tactics
Fraud groups keep swapping the agency they claim to represent and the pretext they use. Knowing the patterns that come up most often is directly linked to prevention.
Police Impersonation
"Your account is being used for criminal activity. You need to move your funds to a safe account" or "Your bank card has been compromised. An officer will come to collect it." These tactics steal money or bank cards directly. Cases involving in-person "collectors" visiting victims' homes tend to result in higher losses.
Tax Office Impersonation
"There's an error in your tax return. You must pay the additional assessment today or your assets will be seized" or "You have a refund - please process it at the ATM." For calls that use a tax refund as the pretext, NPA figures for refund fraud in 2024 show April with the highest number of recorded cases, followed by March and May. Stay especially alert from the filing deadline through the spring.
Pension Office Impersonation
"We need to refund a pension overpayment via ATM" or "There's an issue with your pension eligibility - please provide your personal details." Callers time these to pension payment dates (the 15th of even-numbered months) to make the story sound credible.
Court Impersonation
"A lawsuit has been filed against you. Pay the settlement to have it dismissed" or "A court summons has been issued. Failure to respond will result in arrest." Courts never demand settlement payments by phone.
Immigration Office Impersonation
Targeting foreign residents: "There's a problem with your residence status" or "Your visa renewal has an error." Scammers exploit fear of deportation to extract "processing fees."
Key Facts for Spotting Fakes
Memorize these facts to protect yourself. They apply without exception:
- Government agencies never demand payment by phone: Tax and penalty payments are notified in writing and paid through designated channels
- No ATM instructions are ever given: There is no ATM procedure for refunds or tax payments
- Arrest and seizure are never announced by phone: Legal actions are executed through written warrants
- PINs and bank cards are never requested: Police never collect bank cards
- Prepaid card payments are never requested: Instructions to buy prepaid cards at convenience stores are definitive proof of fraud
Verification Steps
If you receive a suspicious call, follow these steps:
- Hang up: End the call without explanation. Don't worry if the caller gets angry
- Call the real number: Look up the agency's number on their official website or in the phone book and call them yourself. Never use a number provided by the caller
- Search the number: Use phone number lookup services to check for fraud reports
- Consult family: Don't decide alone - discuss the situation with someone you trust
- Contact police: If unsure, call the police consultation line (#9110)
Defending Against Robocall Scams
"This is the XX Police Department. We have an important message for you. Press 1." Automated voice messages like this are classic scam indicators. Pressing a button connects you to a live operator who uses skilled persuasion to extract personal information or money.
Robocalls can reach thousands of numbers in minutes, causing widespread damage. Government agencies do not normally contact individuals via automated calls. Never respond to automated voice calls - hang up immediately. Search the number on lookup services and block it if fraud reports exist.
What to Do If You've Been Scammed
If you've paid money, immediately contact the recipient bank to freeze the account. If you've handed over a bank card, call your bank to cancel the card and freeze the account. If you've shared personal information, notify relevant institutions (banks, card companies, pension offices) to prevent identity theft. Also contact the police (#9110) and Consumer Affairs Hotline (188).
Patterns Seen in Reported Damage
Government impersonation scams press victims to decide quickly under the weight of official authority, so losses tend to grow once the story is believed. The following patterns come up repeatedly.
- Concentrated among older adults: Among victims of special fraud in Japan, those aged 65 and over accounted for 78.4% in 2023 (NPA)
- The phone is the entry point: In the same year (2023), the first contact from the perpetrator was a phone call in 77.5% of cases (NPA)
- Refund pretexts stand out: Claiming a tax or insurance refund and steering the victim to an ATM is the signature pattern of calls that impersonate government agencies
- Uneven across the calendar: For refund fraud in 2024, recorded cases peaked in April (437), followed by March (391) and May (390), with December the lowest at 249 (NPA)
Older adults are especially vulnerable not only because they tend to be less familiar with administrative procedures, but also because the fear of "consequences for non-compliance" overrides rational judgment. And since cases dip at year-end but cluster in early spring, assuming that year-end is the only risky season is a dangerous misconception.
How Government Agencies Actually Communicate
Knowing how real agencies contact citizens helps you distinguish legitimate communications from scams:
- Tax offices: Tax notifications arrive by mail. They never process refunds or demand payments by phone
- Pension offices: Important pension communications arrive by mail. They never request personal or account information by phone
- Police: Arrest warrants and search warrants are presented in writing. They never demand money or bank cards by phone
- Courts: Litigation notices arrive by special delivery (registered mail). They never demand settlement payments by phone
- Municipal offices: Benefit and refund notices arrive by mail. They never instruct ATM operations
If you receive a suspicious call, always call back using the official number from the agency's website or phone directory - never use a number provided by the caller.

Protecting Elderly Family Members
To protect elderly family members from government impersonation scams, practice these measures:
- Regular information sharing: Discuss newly reported scam tactics and reinforce that "government agencies never demand money by phone"
- Family code word: Establish an emergency code word for identity verification during suspicious calls
- Install a call-screening phone: Devices that play automatic warning messages and record calls deter scammers
- Lower ATM limits: Set lower daily transfer limits on elderly family members' accounts
