What Happens If You Don’t Update Your Address After Moving? Fines Sent to Old Address Still Valid—Top 10 Most Commonly Overlooked Procedures Revealed

Moving isn’t just about packing furniture and handing over keys—changing your address triggers a series of data updates. Many people assume that once they update their household registration at the local office, banks, tax authorities, vehicle licensing, and health insurance systems will automatically sync. In reality, not all agencies receive the new address directly. Failing to proactively update information may result in missing tax bills, fines, insurance premium notices, and late fees. In some cases, failing to complete household registration within the legal timeframe can even lead to penalties.

The Ministry of Digital Affairs’ “My e-Government” has compiled a list of address change procedures after moving or updating household registration, covering household affairs, taxation, vehicle licensing, land administration, health insurance, utilities, and National Pension. Below are the 10 most commonly overlooked procedures—those planning to move should verify each one.

Moving Address Change Procedure 1: Household Registration Transfer or Address Update

The most important post-move task is determining whether you need to file for household registration transfer. If you’ve moved from another township, city, or district and will reside at the new address for more than three months, you must complete a “transfer-in registration.” If you’re changing addresses within the same township, city, or district, it’s considered an “address change registration.”

Residents can visit the local household registration office to complete the process. Required documents typically include the applicant’s national ID card, personal seal or signature, household register from both the original and new locations. To establish a new household at the new address, additional documents such as proof of property ownership, rental agreement, utility bills, or other evidence of actual residence are required.

Note that the legal reporting period for transfer-in, transfer-out, or address change registration is “3 months and 30 days.” Failure to file without valid reason may result in a fine of NT$300 to NT$900, depending on the delay. Providing false information to register at an address where you don’t actually live may lead to a higher penalty of NT$3,000 to NT$9,000.

Moving Address Change Procedure 2: Reissuing ID Card and Updating Household Register

After updating your household address, your national ID card must also reflect the new address. When completing transfer-in or address change registration, the household office will simultaneously issue a new ID card. If applying in person and the officer confirms your appearance matches the existing photo, the original stored photo can usually be reused.

If someone else is handling the process on your behalf, a color photo taken within the last two years or a pre-uploaded digital photo may be required. The fee for reissuing an ID card is NT$50 per card; reissuing a household register costs NT$30 per copy.

Moving Address Change Procedure 3: Vehicle Registration and License Plate Address

Owners of cars or motorcycles must also update their vehicle registration and license plate details after changing household registration. According to the Road Traffic Safety Rules, vehicle owners must report changes in name or address to the motor vehicle licensing authority.

Residents can log into the Motor Vehicle Licensing Service Network using a Natural Person Certificate, Business Certificate, or NHI card to check and update vehicle information. Alternatively, bring your ID card, vehicle license, and valid compulsory auto liability insurance (valid for at least 30 days) to a licensing office or station.

Failure to update vehicle registration increases the risk of missing fuel tax notices, vehicle license fees, periodic inspection reminders, parking fee reminders, or traffic violation fines. Even without receiving notifications, you remain liable for these fees, and late payments may incur additional penalties.

Moving Address Change Procedure 4: Driver’s License and Driving Record Address

In addition to vehicle registration, the address on your driver’s license should also be updated. Residents can check and update their driving record address via the Motor Vehicle Licensing Service Network or visit a licensing office in person.

If your actual residence differs from your household registration address—for example, due to work or study—you can apply to add a “residence or workplace address” with the licensing authority. Once registered, official notices and administrative documents will be prioritized to the designated address, preventing fines, inspection notices, or fuel tax bills from being sent to an unoccupied household address.

Moving Address Change Procedure 5: Property Tax, Land Value Tax, Vehicle License Tax, and Income Tax Information

Individuals owning property, land, or vehicles should confirm the mailing address for property tax, land value tax, vehicle license tax, and comprehensive income tax bills. Updating household registration does not guarantee automatic updates for all tax notices, especially if assets are spread across different counties or cities, increasing the chance that tax bills are still sent to the old address.

Residents can use a Natural Person Certificate, Business Certificate, or NHI card to correct tax notice mailing addresses via the Ministry of Finance’s Online Tax Filing System. Alternatively, apply directly to the local tax authority in the jurisdiction where the property or land is located. Chunghwa Post’s address change notification service can simultaneously inform agencies about property tax, land value tax, vehicle license tax, and comprehensive income tax statements.

Moving Address Change Procedure 6: Land Rights Holder Address

Individuals owning land or buildings should also update the “rights holder address” in land registry records. If outdated addresses remain in land administration data, you may miss registration notices, boundary-related documents, or other official correspondence from land offices.

After updating household registration, residents can use a Natural Person Certificate to log into the Ministry of the Interior’s Land Administration Digital Counter and update the address online. Alternatively, bring your ID card, household register copy or transcript, and title documents to the local land office where the property is located.

Moving Address Change Procedure 7: Water, Electricity, and Natural Gas Bills

After moving in, confirm the account holder name and mailing address for water, electricity, and natural gas bills. If renting, at least confirm who is responsible for payment. If purchasing a property or taking over existing accounts, you may need to complete a transfer of ownership.

Taiwan Power Company, Taiwan Water Corporation, Taipei Water Department, and CPC Natural Gas all offer online services to update mailing addresses. Consider switching to e-billing to avoid paper bills being sent to the old address. These utilities also offer joint services at designated locations, allowing you to handle multiple accounts at once.

Moving Address Change Procedure 8: Health Insurance Mailing Address

Most employees’ health insurance premiums are handled by employers. However, individuals enrolled as Class 6 residents or those receiving supplementary second-generation health insurance premium notices should proactively update their health insurance mailing address after moving.

Residents can log into the Personal Health Insurance Online Service or use the “NHI Express” mobile app to update their mailing address under the insurance counter function. Alternatively, visit an NHI Administration service center with valid ID. Failure to update may result in premium notices being sent to the old address, leading to late payments and late fees.

Moving Address Change Procedure 9: National Pension Payment Notice Address

Individuals not enrolled in labor, farmer’s, public servant, or military insurance—and instead covered by the National Pension—must also update their payment notice mailing address.

Residents can use a Natural Person Certificate or Virtual Labor Insurance Certificate to log into the Labor Insurance Bureau’s e-Service System and update National Pension communication details under “E-Billing / Communication Data Change.” Applications can also be submitted by phone or mail. To avoid missing notices after future moves, consider switching directly to e-billing.

Moving Address Change Procedure 10: Mail Redirection and Private Institution Updates

After moving, it’s difficult to immediately notify all senders. You can first apply for “mail redirection” with Chunghwa Post. If the new address is within the original delivery zone, it’s called “re-direction”; if it requires forwarding to another post office, it’s “re-mailing.” The service is valid for six months. After expiration, mail will be delivered to the original address on the envelope.

These six months should only be considered a buffer period. Residents should still individually update mailing addresses for bank accounts, credit cards, insurance companies, securities firms, telecom providers, online shopping platforms, subscription services, dividend notices, and shareholder meeting notices. Even if important documents are sent to the old address and received by a manager or legally deposited at the post office, they may still be considered legally delivered—“I didn’t see it” cannot be used to avoid late fees or penalties.

Cross-Agency Notification via Household Office—Still Verify Results

To reduce duplicate applications, residents can use the Ministry of the Interior’s “Household Data Change Cross-Agency Notification Service” after completing registration to notify tax, vehicle, land, health insurance, labor insurance, Taipower, and water companies of the new address.

However, each agency has different coverage. Some only update household addresses, others only billing addresses. Bank, credit card, insurance, securities, and telecom data are not included in government cross-agency notifications. After moving, keep a checklist of address changes and verify each account individually—otherwise, a single misdirected bill or fine could lead to unnecessary late fees and penalties.
