Notes

  • Delaware uses a single progressive rate schedule (0% on the first $2,000 up to 6.6% over $60,000) that applies to ALL filing statuses for 2025.
  • The lower 2.0%–6.75% schedule enacted by HB 13 applies to tax years after Dec 31, 2025 (2026 onward) and is NOT used for the 2025 tax year.
  • Delaware sets its own standard deduction ($3,250 single / $6,500 joint for 2025), far lower than the federal amount.
  • Delaware grants a $110 personal credit per exemption ($220 for joint filers) plus $110 per dependent, applied against the bracket tax (reported tax is net of this credit).
  • Delaware starts from federal AGI and conforms to the federal HSA deduction (no HSA add-back); itemized deductions follow the federal definition but add state income tax back, so state income tax is not deductible.
  • Not modelled: the additional $2,500 standard deduction and additional $110 personal credit available to taxpayers age 65+/60+ or blind (no age/blindness input).
