Virginia Tax Planning Tip
Virginia’s income tax tops out at 5.75% on income over $17,000. S-Corp and partnership owners should evaluate the pass-through entity tax (PTET) election, which lets the entity pay state tax and deduct it at the federal level, effectively bypassing the $10,000 SALT cap. Virginia generally conforms to federal tax law but decouples on certain provisions, so check conformity dates before claiming federal deductions on your state return.
