Will I be double-taxed working in two states?

Usually no. The residence state credits tax paid to the work-location state. You file in both states but pay total tax close to what you would have paid in just one.

How do I know if my states have reciprocity?

Check the residence state's Department of Revenue website. Common pairs: PA-NJ (limited), IL-IN, MD-VA, WI-IL, MI-IN, KY-IN. File the exemption form with payroll.

My employer only withholds for one state. Is that wrong?

Maybe. If your work crosses state lines and reciprocity does not apply, the employer should withhold for the work state. If they are not, raise it with payroll. You may owe estimated taxes to the second state at year-end.

Multi-State Payroll Guide

Working across two or more states adds layers to your payroll. Different residence and work-location withholding, reciprocity rules, and a tax return in each state. Here is the playbook.

PayslipIQ provides educational information and estimated calculations only. It does not provide tax, legal, financial, accounting, employment, benefits, or payroll advice. PayslipIQ is not a CPA firm, law firm, financial advisor, payroll provider, or tax authority. Always verify your paycheck, deductions, withholdings, and tax position with your employer's payroll department, a qualified CPA, the IRS, your state tax authority, or another appropriately qualified professional. Calculations are estimates; your actual paycheck may differ based on factors specific to your employer, location, benefits elections, and personal tax situation.

Three layers

Multi-state payroll has residence-state withholding, work-location-state withholding, and reconciliation at filing time. Each state's rules differ, and the interaction depends on the pair.

Common scenarios

Cross-border commute (NJ to NYC)

You live in New Jersey, work in NYC. NJ taxes you as a resident on all income. New York taxes you on NY-source wages. NJ allows a credit for tax paid to NY. NYC tax is residence-based: a non-resident does not pay NYC tax even when working in NYC.

Reciprocity

If your states reciprocate (PA with NJ for some scenarios, IL with IN, MD with VA, WI with IL), file the exemption form with payroll so only the residence state withholds.

Hybrid in-office plus home

Both states may apportion your wages based on where you actually worked. Keep records.

Permanent remote, employer in different state

Usually you pay only your residence state. Unless the employer's state applies the convenience rule (NY, CT, DE, NE, PA in some cases), in which case you pay both.

What to ask payroll

Which state are you currently withholding for?
Have you applied a reciprocity exemption?
Do you track days worked in each state?
What W-2 boxes will reflect each state at year-end?

Use the Ask Payroll generator to draft these.
