Worked Example

Isaiah lives in Pikeville KY, works in Williamson WV, earns $48,000. With reciprocity: files WV/IT-104R with WV employer. WV withholds $0. KY withholds ~$1,680 (3.5% flat). Saves filing a two-state return plus captures the KY-WV 1.32pt rate gap in worst case.

Step-by-Step: Claim the Exemption

  1. Download the work-state exemption form (WV form WV/IT-104R for KY-residents-working-in-WV; KY form 42A809 for WV-residents-working-in-KY).
  2. Fill in name, SSN, home address (must be in the reciprocity state), and current date.
  3. Submit to HR/payroll at your employer.
  4. Verify on your next paystub that work-state tax withholding is $0.
  5. Update your home-state W-4 to make sure you withhold enough for full income tax.
  6. File only a resident return in your home state next April (unless you have non-wage work-state income).

OBBBA 2026 Note

OBBBA 2026 (One Big Beautiful Bill Act) raised the federal SALT cap to $40,000. This matters for reciprocity commuters who itemize: your full home-state income tax is now more likely to be fully deductible on federal Schedule A, making the state-level tax difference between your home and work state a real after-tax driver of commute value. Check each state rate: KY top rate 3.5% flat (2026), WV top rate 4.82% top (2025).

FAQ

Are both KY and WV on scheduled rate-cut paths?

Yes. Both states passed rate-trigger legislation. KY's flat rate dropped to 3.5% for 2026 after HB 1 revenue triggers were met. WV is phasing down from 5.12% to 4.82% with further cuts scheduled.

Which form does a KY resident working in WV file?

Form WV/IT-104R (Certificate of Nonresidence) with the WV employer. Keep a copy for personal records in case of audit.

Do coalfield workers have any special reciprocity provisions?

No special provisions. Standard state reciprocity applies to mining, logging, and other wage income. 1099 contractor income is NOT covered - it follows source-state rules.

What about per diem or travel pay for KY residents working in WV?

Per diem that meets IRS substantiation rules is non-taxable federally and usually state-excluded as well. Any taxable portion follows the same reciprocity treatment as W-2 wages.

Can a KY LLC owner working in WV use reciprocity?

No. LLC/S-Corp pass-through income is NOT W-2 wages and reciprocity does not apply. The income is taxable in WV as nonresident source income requiring a WV nonresident return.
