A $75,000 salary in Seattle needs to be about $66,200 in Austin to keep pace with local prices. Taxes barely move in this move: the same $75,000 takes home exactly the same in Texas as in Washington - on this route the money math is prices, not taxes. Here is the full money math, plus the paperwork checklist that actually changes when you cross a state line.
The money math
What your salary needs to be
| From (anchor metro) | To (anchor metro) | $75,000 becomes | Price gap |
|---|---|---|---|
| Seattle (RPP 111.1) | Austin (RPP 98.1) | $66,200 | -11.8% |
| Seattle (RPP 111.1) | Dallas (RPP 103.1) | $69,600 | -7.2% |
Equivalent salary = $75,000 x destination RPP / origin RPP, using BEA Regional Price Parities (US average = 100) for the anchor metros of each state on this route. Rounded to the nearest $100.
Take-home pay at $75,000 in both states
| State | Federal tax | FICA | State income tax | Take-home | Effective rate |
|---|---|---|---|---|---|
| Washington | $7,670 | $5,738 | $0 | $61,592 | 17.9% |
| Texas | $7,670 | $5,738 | $0 | $61,592 | 17.9% |

The state tax switch
Washington levies no state income tax on wages, and so does Texas. At $75,000 the state tax line is $0 in both states: on this route the money math is entirely prices.
What changes when you move
Three pieces of paperwork follow every Washington to Texas move. The deadlines are set by state law and they differ, so treat each agency’s own page as the source of truth:
- State tax residency. The year you move you will generally file a part-year return in each state, splitting income by when you earned it. Give both agencies your move date: Washington Department of Revenue and Texas Comptroller of Public Accounts.
- Payroll withholding. Update your address with payroll, refile your federal W-4, and drop the Washington state withholding form: Texas levies no state income tax on wages, so only federal withholding applies. The Texas paycheck calculator shows the new net pay.
- Driver’s license and vehicle registration. Every state gives new residents a window, typically 30 to 60 days, to swap a license and plates. Check the current deadline at the Washington DOL and the Texas DMV.
The move itself is the one cost we quote no dollars for: it swings too far between a self-drive and a full-service interstate move to generalize. Whatever the quote, verify the mover before paying a deposit: Protect Your Move (FMCSA).
