State tax lines move fast in 2026: income tax changes, part-year splits, reciprocity forms, remote work rules, and severance lines all stack in the transition year. The quick map is the audit order.
The Map Order
- Work location: wage lines follow the work state, not the office; the remote jurisdiction is in the remote termination guide, and the W-2 lines in the final W-2 guide.
- Part-year & reciprocity: mid-year moves create two returns, credits avoid double tax, and signed exemptions keep one state on the other's wages (see the reciprocity guide and the cross-state guide).
- Severance & PTO: state income lines, offsets, and final-pay deadlines; the map is in the severance map and the wage claim in the wage claim guide.
The ACA subsidy lines are in the special enrollment guide, the year crossing in the new-year guide, and the records in the records guide.
Put the rule into action
Write the letter with the free Final Paycheck Demand Letter generator. The state pages carry the local payout and notice windows, and the application tracker keeps the follow-up date in writing.
The Audit Order, In Six Steps
Direct answer: work the year in this order, because each step changes the next. Guessing the state first is how people end up amending a return in April. The map below is the sequence, not a set of rates.
- List every state you worked in and every state you lived in, by month. Payroll records are not proof of work location; your own calendar and remote-week log are.
- Collect every Form W-2, 1099, and 1095-C before systems access ends. See the W-2 and 1095-C entries; two employers plus a severance line is the typical mismatch.
- Split the wages across the months. Part-year and nonresident returns allocate by dates, so put the last day worked and the move date on one page.
- Check exemption certificates and reciprocity. A missing certificate explains double withholding and a two-return year; see the reciprocity rules and the state pages.
- Then handle exit money: final pay, accrued PTO cash-out, severance, bonus, and relocation reimbursement. Each has its own state line, and the payout deadlines that drive them are on the state final-pay pages.
- Finally reconcile benefits. Subsidy math and coverage months come from the marketplace and employer forms; the ACA enrollment window is described in the special enrollment entry.
Which Money Lines Move When You Change States
Salary is the easy line. Everything else at separation has its own sourcing rule, and several of them depend on the date you changed residency rather than the date you were paid.
- Severance. Lump sums and monthly continuation can be sourced differently, and the payment year can differ from the earning year; see the state offset categories in the severance offset entry.
- Accrued PTO cash-out. Often treated as final wages, which follows the state whose wage rules applied at separation.
- Bonus and commission true-up. Paid after you leave but earned earlier, so the source state argument is about when the compensation was earned.
- Relocation gross-up. Taxable income in most moves after 2018, and the state line depends on where you lived when it was paid; the gross-up entry explains the multiplier question.
- Equity income at vesting. Reported where the work that earned it happened, which can be a state you left months earlier; see the Equity & Tax guides.
- Unemployment benefits. Taxable federally, and state treatment varies; check the current rule rather than an old return.
Cases The Quick Map Misses
The three situations below are where a fast map leads to a wrong filing. Treat each as a question to ask the revenue department, not a rule to assume.
- Mobile work across several states. Short stints in client states can create filing duties in states you barely worked in. Keep the travel log, then check each state's threshold and filing duty.
- Employer registered because of you. A remote employee can trigger a business tax registration in the new state, which changes what payroll reports. Ask payroll, in writing, which state they report your wages to.
- Two states, one set of wages, no credit. If both states claim the same income and neither grants a credit, the fix is on the worksheet, not in an explanation. Get the worksheets from both states and reconcile before filing.
Where a rule was not re-verified in this build, the state page says so plainly. Use that wording in your own notes: verify with the state agency, then record the date you checked. Log the dates on the tracker and keep the exit paperwork in one folder.
| Money Line | Usually Taxed By | Verify Before Filing |
|---|
| Regular wages | The state where work was performed | Remote-week log and payroll state |
|---|
| Severance lump sum | The source state at payment | Payment date versus residency change |
|---|
| PTO cash-out | The state whose wage rules applied | Whether it is reported as final wages |
|---|
| Bonus paid post-exit | Where it was earned | Earned period and reporting year |
|---|
| Relocation gross-up | Where you lived when paid | Receipts versus lump grant treatment |
|---|
| Equity income at vest | Where the earning work happened | Work-state history for the grant period |
|---|
Frequently Asked Questions
- What is the fastest way to map my state tax year?
- Build it from dates and documents: the states you lived and worked in by month, every W-2 and 1095-C, then the split of wages across the move date. After that, handle severance, PTO, bonus, and relocation lines in order, and finish with the marketplace forms.
- Why did two states tax the same wages?
- Usually because one state claims the income by residence and the other by work location, and no exemption certificate or credit worksheet was applied. Both states publish worksheets; use them instead of explaining the overlap on the return.
- Do short work trips in another state create a filing duty?
- They can. Some states impose a filing or registration duty once a nonresident earns wages there, even briefly. Keep the travel log and check the threshold with that state's revenue department before you assume one return covers the year.
- Where do I confirm a rule the quick map marks as unverified?
- With the state agency named on that state's page. Treat unverified entries as questions to ask, not numbers to quote, and record the date you confirmed the answer so a later dispute has a source and a timestamp.
