What's the difference between the SEP-IRA Contribution federal vs Massachusetts state treatment?
The SEP-IRA Contribution is a FEDERAL deduction — federal eligibility rules apply uniformly nationwide. Massachusetts's difference is at the state-level conformity: most states "couple" with federal AGI calculations, meaning the deduction reduces your Massachusetts taxable income too. Massachusetts top state rate is 5%, so each $1,000 of federal-deductible expense saves you an additional $50 in Massachusetts state tax. Some states "decouple" from federal — verify Massachusetts's 2026 state tax form for confirmation.

The SEP-IRA Contribution caps at $69,000 per year for tax year 2026. Federal phase-outs depend on your modified adjusted gross income (MAGI) — high-income filers may see reduced or fully phased-out benefits. Check IRS Publication 5498 for the 2026 phase-out thresholds. Massachusetts state-level conformity means the same federal phase-out reduces your state benefit proportionally at the 5% top marginal rate.
What records should I keep for the SEP-IRA 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 5498 and Schedule C as filed, and any correspondence from payors or institutions. Common mistakes that trigger audit scrutiny include: Exceeding 25% limit; Not including employees. Digital scans are accepted by the IRS — back them up to cloud storage with date-stamped filenames.
