As a W2 employed full-time or contract worker living and working in different states, you will be responsible for your own tax filing. You should investigate which state will tax your paycheck. State tax reciprocity agreements can simplify this situation.
ERA’s experts explore “What is a reciprocal state,” how they benefit you, and which states have them in place for 2024. By the end, you clearly understand how these agreements work and how they can save you time and money on your tax filings.
A state tax reciprocity agreement is a pact between two or more states eliminating double taxation for workers who commute across state lines. In simple terms, if you live in State A but work in State B, and these states have a reciprocity agreement, you only pay income tax to your state of residence (State A). This helps you avoid the inconvenience of having to submit tax returns to both states.
Here are some individuals who should be familiar with state tax reciprocity agreements:

State tax reciprocity agreements are vital in simplifying tax filing and saving money for workers who commute across state lines. Here’s a closer look at their importance:
For example, Sarah lives in Kentucky and works remotely for a company in Ohio. Kentucky has a lower income tax rate (5%) than Ohio (3.94%). Without a reciprocity agreement, Sarah would pay Ohio taxes on her income, even though she doesn’t live there.
Here’s a simplified breakdown:
In this scenario, because of the reciprocity state agreement, Sarah saves nearly $530 on her state income taxes.

A reciprocal agreement between states’ taxes eliminates double taxation for workers who commute across state lines. If your state has a reciprocity agreement with the state where you work, you’ll only pay income tax to your home state.
Reciprocal agreements can vary and change over time. Some examples of states having historically had reciprocal agreements include Pennsylvania and New Jersey, Illinois and Iowa, Wisconsin and Minnesota, and Maryland and Virginia. However, verifying the current status of reciprocal agreements is essential, as they may be subject to change.
If your state lacks a reciprocity agreement with the state where you work, you’ll likely need to file tax returns in both states. This can be complex, so it’s recommended you consult with a tax professional.
“Reverse credit” refers to a state policy allowing residents to claim a credit for taxes paid to another state. This differs from a reciprocity agreement, but it can offer some relief for double taxation. Research your state’s tax laws to see if they offer a reverse credit.
