The change-of-address master list

Start with USPS mail forwarding

File a change of address with USPS, online or at the post office, ideally 7-10 days before your move date. Standard forwarding for first-class mail typically runs before it stops, and periodicals and some other mail classes forward for a shorter window. Treat this as a safety net that catches stragglers, not as your actual address-change plan — plenty of important mail, especially from government agencies and financial institutions, doesn't forward cleanly or at all.

Be aware that mail forwarding is also a well-known target for mail theft and address-change fraud; use the official USPS site directly rather than a third-party site that charges a fee to 'process' your forwarding request.

Government accounts: update these first

Government mail and notices are the ones you most need not to miss — tax notices, benefit correspondence, and passport renewals all have real deadlines attached.

• IRS — file Form 8822, Change of Address, separate from your tax return; don't rely on your next filed return to update it
• Social Security Administration — update your address through your my Social Security account or by calling SSA; this matters most if you're already receiving benefits
• California DMV — notify DMV within if you're keeping a California license temporarily, or begin surrendering it if you're getting a new-state license; see Car, license, and registration in a new state
• Voter registration — register in your new state and confirm your California registration is cancelled, not just dormant
• Passport — update your address with the State Department if you have a pending application; existing passports don't need an address change to remain valid
• Your state tax agency in the new state, once you've established residency there

Financial accounts

Financial institutions use your address for statements, tax documents (1099s, 1098s), and sometimes fraud monitoring, so these are worth doing promptly and in one sitting if you can.

• Primary bank and any secondary banks or credit unions
• Credit cards — all of them, not just the one you use most
• Brokerage and retirement accounts (401(k), IRA custodians)
• Mortgage or landlord/property manager for any property you still own
• Auto, home or renters, and umbrella insurance — see Insurance after moving states
• Student loan servicer
• Any recurring payment accounts tied to an old address for verification (PayPal, Venmo, etc.)

Employer, payroll, and benefits

Your employer needs your new address before your move takes effect, not after, because it affects state tax withholding and sometimes benefits eligibility.

• HR/payroll system — update your legal address for withholding purposes
• Health insurance carrier, if staying on an employer plan that covers your new state
• 401(k)/retirement plan administrator
• HSA or FSA administrator
• Any professional licensing board that requires a current address on file — see Transferring a professional license

Everyday accounts and subscriptions

These don't carry legal weight, but missing them is how people end up with months of misdirected packages and renewal notices.

What to actively cancel in California, not just update

A few California-specific accounts should be closed or cancelled outright rather than left with a forwarding address, both because they're no longer useful to you and because leaving them active can muddy a clean residency change — see Cutting ties cleanly with California for the full list and why it matters for taxes.

• California voter registration
• Covered California health coverage, once you have coverage in your new state — see Health insurance when you leave California
• California utility accounts (electric, gas, water, trash) — request final readings, not just a stop date
• Local gym, club, and association memberships that don't have a presence in your new state
• Any California P.O. box you no longer need

A sensible order of operations

Doing all of this in one day isn't realistic, but doing it in a sensible order keeps anything important from slipping through the cracks.

1. 2-3 weeks before the move: file USPS forwarding, notify your employer, start transferring professional licenses or memberships that take time to process
2. Moving week: update DMV, voter registration, and insurance to reflect the move date
3. First week after arrival: update banks, credit cards, brokerage and retirement accounts
4. First month: IRS Form 8822, Social Security, remaining subscriptions and everyday accounts
5. First 90 days: confirm nothing is still routing to the old address, and formally cancel anything California-specific you no longer need
