The filing deadlines for state taxes can vary, but they often align with federal tax deadlines. For individual income tax returns, the deadline is typically April 15th, following the federal due date. However, some states may have different due dates, such as May 1st for Delaware and Iowa. For businesses, the filing deadlines depend on the entity type and tax type. For example, sales tax returns are typically due monthly or quarterly, while payroll tax returns are usually due quarterly or annually. It’s essential to check the specific deadlines in your state to avoid late filing penalties.
