This tool gives a planning estimate using 2026 federal figures. It does not compute state estimates, the annualized income installment method, the alternative minimum tax, or credits that depend on facts it does not ask about. Your actual liability depends on your complete return. For a figure you can rely on, work with your Enrolled Agent.
