Moving to Seattle: The First 30 Days Checklist (Food Waste Is Required, RTA Tax Surprises)
Washington gives you 30 days for both license and vehicle registration — and the registration comes with Seattle’s famous surprise: the RTA transit excise tax, which can push a newer car’s tab past $500. City Light for power, Puget Sound Energy for gas, mandatory food-waste sorting by ordinance, every ballot by mail, and no state income tax. Here’s the sequence.
The 30-Day Timeline
| When | Task | Detail |
|---|---|---|
| Before/Day 1 | Electric | Seattle City Light — city-owned, cheap hydro power (your bill will pleasantly surprise you) |
| Day 1 | Gas (if applicable) | Puget Sound Energy — many Seattle homes are all-electric |
| Day 1 | Internet | Xfinity, CenturyLink/Quantum Fiber, Astound (Wave) — fiber coverage is decent and improving |
| Week 1 | Water/sewer/trash | Seattle Public Utilities one account — garbage, recycling, and food/yard waste, which is mandatory (composting food scraps is required by city ordinance) |
| Week 1–4 | WA driver’s license — 30 days | DOL offices; WA is also an enhanced-license state (EDL works for land border crossings) |
| Week 1–4 | Vehicle registration — 30 days | The sticker shock: inside the Sound Transit district, the RTA excise tax (value-based) stacks on regular fees — $300–$700 total is common on newer cars; no emissions or safety inspection though |
| Anytime | Voter registration | Washington votes entirely by mail; register online (8-day cutoff) or same-day in person at vote centers |
| Month 1 | Rain-season prep (if you bought) | Gutters, downspouts, and drainage before October — Seattle plumber rates and moss-on-roof realities are the local homeowner curriculum |
Utilities Cheat Sheet
| Service | Provider | Notes |
|---|---|---|
| Electric | Seattle City Light | Among the cheapest big-city power in the U.S. (hydro) |
| Gas | Puget Sound Energy | Where homes have gas |
| Water/sewer/trash/compost | Seattle Public Utilities | Food waste in the garbage violates city ordinance |
| Internet | Xfinity / Quantum / Astound | Shop by exact address |
The Seattle-Only Quirks Worth Knowing Early
- The RTA tax is the transplant rite of passage — value-based transit tax on registration renewals inside the Sound Transit district; budget for it before the DOL visit, not after
- No state income tax (WA taxes capital gains above a high threshold, not wages) — sales tax (~10%+ in Seattle) is where the state collects
- Rain is a drainage problem, not an umbrella problem: locals don’t carry umbrellas, but homeowners obsess over gutters, grading, and crawl-space moisture — basement/crawl waterproofing is a real line item here
- Moss owns every roof eventually — annual treatment beats premature roof replacement
- The electrification push is real: heat pumps, EV chargers (Seattle electrician guide) — and WA contractor verification plus insurance certificates are standard hiring hygiene
- Arriving by truck? Seattle moving rates — summer is tight, book early
Frequently Asked Questions
Why is registering my car in Seattle so expensive? The RTA (Sound Transit) excise tax — a value-based tax stacked on standard fees for addresses inside the transit district. Newer cars commonly land at $300–$700 all-in. The consolation: no emissions or safety inspections in WA.
Is composting food waste really mandatory in Seattle? Yes — city ordinance prohibits food scraps in garbage; they go in the food/yard waste cart that comes with SPU service. Enforcement is mostly educational tags on bins, but the rule is real.
How does voting work in Washington? Entirely by mail — every registered voter gets a ballot automatically. Register online up to 8 days before an election, or same-day in person at a vote center. Drop boxes are everywhere.
Does Seattle have a state income tax? No tax on wages. Washington collects through sales tax (10%+ in Seattle) and fees like the RTA. For most W-2 transplants from California or New York, take-home pay rises noticeably.
Do I need AC in Seattle? Increasingly, yes — heat events are now regular and most older housing has none. Heat pumps (cooling + efficient heating) are the local default answer; see AC installation costs and utility rebates before summer.
