Conformity (Tax Bulletin 26-1)
HB 29, effective February 20, 2026, fixes conformity at December 31, 2025. Virginia does not follow the federal expensing for qualified production property, domestic research expenditures (including the retroactive and catch-up rules), or the higher section 179 limits. Bonus depreciation stays one of Virginia’s existing exceptions.
Virginia keeps the federal section 163(j) change, but its subtraction for disallowed business interest falls from 50% to 20% for 2025 and later. Virginia also keeps the Pease limitation on itemized deductions.
