Delaware gambling tax calculator

Delaware allows gambling losses only as an itemized deduction on the state return, whether or not you itemize federally. Take its standard deduction and it taxes your gross winnings. Whether only 90 percent of your losses count from 2026 is not settled.

How Delaware treats gambling losses

Delaware does not tie the deduction to your federal itemizing choice. You can itemize on the Delaware return even if you take the federal standard deduction, but the losses count only if you do, in place of Delaware's standard deduction.
