8 provisions identified: 4 benefits, 1 costs, 3 mixed.
Beginning January 1, 2026, you get a D.C. credit equal to 24.25% of your federal child and dependent care credit. You must qualify for the federal credit. This nonrefundable credit applies against your D.C. income tax. It helps with work‑related care costs for children or adult dependents.
For tax years beginning January 1, 2026, D.C. provides a refundable $1,000 credit per qualifying child. The credit falls by $50 for each $1,000 (or part) your AGI is over: $55,000 (single or head of household), $70,000 (joint/combined), or $35,000 (married filing separately). You must claim the child on both federal and D.C. returns and have been a D.C. resident for the entire prior calendar year. The per‑child amount is indexed after 2026. The law repeals earlier 2025 child credit acts and replaces them with this program.
Starting January 1, 2025, D.C. classroom teachers can deduct up to $500 for supplies and up to $1,500 for tuition and fees. You must have taught the whole year (or the whole prior year) in a D.C. public or approved charter school. You cannot also claim these same expenses in your federal adjusted gross income for that year. The maximum total deduction is $2,000.
Beginning January 1, 2025, D.C. includes a federal special depreciation allowance in its tax rules. Investors in shared‑equity financing can also claim a D.C. depreciation deduction under the new section. These faster write‑offs can lower D.C. taxable income for businesses and qualifying investors.
Starting January 1, 2025, you can deduct state and local taxes on your D.C. return without the federal limit. If your D.C. adjusted gross income is over $200,000 ($100,000 if married filing separately), your itemized deductions are cut by 5% of the excess. Estates and trusts are not subject to this cut. Some deductions stay banned, including D.C. income or franchise taxes, certain pass‑through and business deductions, qualified tips and overtime, personal car loan interest, and a prior senior add‑on. If spouses or domestic partners file separate D.C. returns and one itemizes, both must itemize. Estates and trusts follow the new fiduciary/itemized rules, and a related estates-and-trusts paragraph is repealed.
Beginning January 1, 2025, D.C. sets a new basic standard deduction: $15,000 (single or separate), $22,500 (head of household), and $30,000 (joint). These amounts are indexed after 2025 and rounded down to the next $50. The D.C. standard deduction equals the basic amount plus any extra amount for age or blindness allowed under federal law. The law repeals D.C. personal exemptions. You must file a D.C. return if your gross income is at least your basic standard deduction.
For investments in Qualified Opportunity Funds after December 31, 2026, D.C. capital gains benefits apply only if the fund meets new legal standards. If the fund qualifies, you can still seek the usual 5‑year basis boost and 10‑year gain exclusion. If it does not, you lose D.C. tax benefits for those gains.
Effective January 1, 2025, the Chief Financial Officer runs D.C. withholding rules and rate references. Withholding uses the highest applicable D.C. tax rate on the base instead of a flat 5%. For pay periods after December 31, 2017, you may claim extra withholding exemptions equal to your estimated itemized deductions divided by a CFO‑set number. A related percentage in a withholding rule increases from 85% to 100% in 2025. These changes can raise or lower paycheck withholding and let you better match it to your deductions.
