state income tax return

A state income tax return is a document that individuals and businesses file with their state government to report their earnings and calculate how much state income tax they owe. Each state has its own tax laws and rates, which can vary significantly. Taxpayers typically include income from wages, investments, and other sources. Deductions and credits may reduce the amount of tax owed. Filing this return is usually required annually, and it helps ensure compliance with state tax laws while contributing to public services and infrastructure. Some states may also offer refunds if too much tax was withheld during the year.
