Income tax in Delaware

Delaware taxes income above a $2,000 exempt threshold at rates from 2.2% to 6.6%, with the same brackets for all filing statuses; the top rate applies above $60,000. A 2025 law restructuring the brackets with new 6.75% and 6.95% top rates takes effect in 2026, not 2025. Wilmington levies a separate 1.25% local wage tax not included here.
