Why week one matters most
Address changes fall into three categories: things that have legal deadlines (DMV), things that have financial consequences if delayed (insurance, banks), and things that are just convenient to do. Week one is about the first category — and getting your safety net (USPS forwarding) in place for everything else.
Day 1 (or before move day): USPS Mail Forwarding
This is your most important action. File at usps.com/move for $1.10. All first-class mail from your old address will forward to your new address for up to 12 months. This catches everything you haven't updated yet. Do this before your move date if possible — USPS typically begins forwarding within 7–10 business days of your requested start date.
Day 1–3: Auto Insurance
Call your auto insurer or update online before you start driving from your new address. This is not just administrative — your policy's coverage terms are tied to your garaging address. A mismatch on the day of an accident is a claim risk.
Day 1–7: Employer HR and Payroll
Log into your HR system (Workday, ADP, Gusto, Paychex, TriNet, etc.) and update your address. Your W-2 for the current tax year will be mailed to whatever address HR has on file on or around December 31. If you move in August and don't update HR, your W-2 goes to your old address in January. Update this in week one.
Days 1–10 (some states): Driver's License and Vehicle Registration
California, New York, Illinois, Maryland, Kentucky, Nevada, Connecticut, and New Jersey all have 10-day deadlines. If you live in one of these states, your DMV update cannot wait. See your state's specific guide for the online portal link.
Within 30 days: Everything else in Tier 1
All remaining states have 15–60 day deadlines for DMV updates. SSI recipients must report within 10 days by law. Voter registration deadlines vary by upcoming election dates. See the complete list for full tier breakdown.
