North Carolina top state rate is 3.99%, so each $1,000 of federal-deductible expense saves you an additional $40 in North Carolina state tax. Some states "decouple" from federal — verify North Carolina's 2026 state tax form for confirmation.

The Defined Benefit Plan Contribution caps at $275,000 per year for tax year 2026.

What records should I keep for the Defined Benefit Plan Contribution in case of an IRS audit?
Keep these records for at least 3 years after filing (6 years if you under-reported income substantially): receipts, invoices, bank/credit card statements showing the expense, Form 5500 and Schedule SB as filed, and any correspondence from payors or institutions.
