Check whether the same income was taxed by multiple states and organize the returns and payment evidence needed for a resident credit.
Answer a few quick questions below. It is private - nothing is submitted or stored - and takes about a minute.
Informational multistate tax screening only; state and local rules vary and must be verified for the applicable year and jurisdiction.
Here is what the checker asks and why each step matters. Prefer to talk it through? Contact us and we will help directly.
A resident credit exists to prevent the same dollar of income from being taxed twice - if only one state reached the income, there is nothing to relieve.
Confirm single-state sourcing and stop here - with income taxed by only one state, the resident credit under your home state's statutes has nothing to relieve.

A handful of neighboring states agree that commuter wages are taxed only by the residence state, which replaces the credit with a simple exemption certificate - commonly among states like IL-IA, PA-NJ, and the DC-area pacts; confirm each pair's current agreement.
File the residence state only and give your employer the reciprocity exemption certificate, so the work state does not tax the covered wages under the two states' reciprocity agreement.

The resident credit is normally claimed on your home-state return for tax the source state charged you as a nonresident - so which state is home decides which return carries the credit.
Resolve dual residency first under each state's domicile and statutory-residency (183-day) tests, then claim the credit on the state each pair assigns.

When the entity elects PTET, the tax is often paid and credited at the entity level, so an owner claiming the same amount again as a personal resident credit can double-count - the two credits must be coordinated.
Coordinate the resident credit with the entity-level PTET credit before you file, since PTET paid under a Notice 2020-75 regime is often credited at the entity level. Claim the resident other-state credit on your home-state return, limited to the lesser of the source-state tax or your home-state tax on the same income (the credit need only be substantially complete under Wynne).
