State Tax Reciprocity: Working Across State Lines

What reciprocity means

State tax reciprocity is an agreement between two states: if you live in State A and work in State B, State B won't withhold income tax from your paycheck. You file only in your home state (State A). Without reciprocity, both states may claim a right to tax your income, and you file in both — typically getting a credit in your home state for taxes paid to the work state.

The practical difference: with reciprocity, your paycheck only has your home state's tax withheld. Without it, the work state withholds tax, and you must file a non-resident return in the work state plus a resident return in your home state (claiming a credit). The total tax is roughly the same, but the paperwork is much heavier without reciprocity.

Our take-home calculator shows your state's income tax. If you work across state lines, check whether your two states have reciprocity — it could save you from filing two returns.

States with reciprocity agreements

Not all states have reciprocity, and the agreements are specific to state pairs. Here are the major reciprocity agreements as of 2024:

• DC ↔ Maryland and Virginia: residents of DC, Maryland, and Virginia who work in any of the three don't pay tax to the work state — only their home state. This is the most commonly used reciprocity agreement.
• New Jersey ↔ Pennsylvania: residents who work across the border file only in their home state. This saves many commuters in the Philadelphia metro area from dual filing.
• Illinois ↔ Iowa, Indiana, Kentucky, Michigan, Wisconsin: Illinois has reciprocity with all its border states.
• Ohio ↔ Indiana, Kentucky, Michigan, Pennsylvania, West Virginia: Ohio has broad reciprocity with its neighbors.
• Pennsylvania ↔ Indiana, Maryland, New Jersey, Ohio, Virginia, West Virginia: Pennsylvania has one of the widest reciprocity networks.

What happens without reciprocity

If you live in California and work in Nevada (no reciprocity), Nevada has no income tax — so you owe nothing to Nevada. But California taxes its residents on all income, including out-of-state wages. You file only in California. This is the best case: no work-state tax, home state taxes everything.

If you live in New Hampshire (no income tax on wages) and work in Massachusetts (5% flat income tax, no reciprocity), Massachusetts withholds 5%. You file a non-resident MA return. NH has no income tax to file. Net: you pay MA's 5%, period.

The worst case: you live in a high-tax state and work in another high-tax state without reciprocity. You owe the work state its non-resident rate, then file in your home state and claim a credit — but the credit is usually limited to what your home state would have charged on that income. If the work state's rate is higher, you eat the difference. If lower, your home state charges the remainder.

The 'convenience of the employer' rule

Some states (notably New York, Connecticut, Delaware, Nebraska, and Pennsylvania) use the 'convenience of the employer' rule. If your employer is based in New York and you work remotely from another state for your own convenience (not because the employer requires it), New York taxes you as if you worked in New York.

This means a remote worker in Florida (no income tax) employed by a New York company may still owe New York state tax — even though they never set foot in New York. The Tax Foundation has challenged this rule, and several states have considered legislation to block it, but as of 2024 it remains in effect.

If you're considering remote work across state lines, check both states' rules. The state income tax calculator shows each state's rate, but reciprocity and convenience rules add a layer that requires checking your specific situation.

Remote work and state tax in 2024

The rise of remote work has made state tax more complex. If you work remotely for a company in another state, your tax liability depends on: where you physically perform the work (your home), where your employer is based, and whether the two states have reciprocity or convenience rules.

Generally, you owe income tax to the state where you physically work (your home state). But if your employer is in a convenience-rule state (like New York), you may owe tax there too. Some states have 'economic nexus' rules that tax remote workers based on the employer's location.

The safest approach: consult a tax professional if you work across state lines. The general rules here cover most cases, but state tax law changes frequently and individual situations vary.
