Is a SIMPLE IRA Tax Deductible?

Quick Answer: ✅ Yes — Employer contributions to a SIMPLE IRA are fully deductible, and employee contributions reduce taxable income through salary deferral.

The Short Answer

SIMPLE IRAs (Savings Incentive Match Plan for Employees) offer tax benefits on both sides. If you're an employer, your matching or non-elective contributions are fully deductible as a business expense. If you're self-employed, your contributions reduce your adjusted gross income. Employee salary deferrals reduce the employee's taxable income. It's one of the most tax-efficient retirement plans for small businesses with 100 or fewer employees.

IRS Rules for Deducting SIMPLE IRA Contributions

Under IRC Section 404(m) and IRS Publication 560 (Retirement Plans for Small Business), employer contributions to a SIMPLE IRA are deductible on the business tax return. The employer must either: (1) match employee contributions dollar-for-dollar up to 3% of compensation, or (2) make a 2% non-elective contribution for all eligible employees regardless of whether they contribute. Self-employed individuals deduct their own contributions on Form 1040, Schedule 1 (adjustments to income), not on Schedule C.

How Much Can You Deduct?

How to Categorize in QuickBooks

• QBO Category: Payroll Expenses — Retirement Contributions
• Schedule C Line: Line 19 (Pension and profit-sharing plans) for employer contributions
• Tip: Set up the SIMPLE IRA as a payroll deduction item in QBO Payroll. This ensures employee deferrals are correctly withheld and employer matches are tracked automatically.

Common Mistakes to Avoid

1. Missing the contribution deadline. Employee salary deferrals must be deposited within 30 days of the end of the month they were withheld. Employer contributions are due by the tax filing deadline (including extensions).
2. Self-employed individuals deducting contributions on Schedule C. Your own SIMPLE IRA contributions go on Form 1040, Schedule 1, Line 16 — NOT on Schedule C. This is an adjustment to income, not a business expense.
3. Exceeding the 3% match or failing to make the 2% non-elective. You must choose one employer contribution method and apply it consistently for the year. Failing to make required contributions creates compliance issues.

Record-Keeping Requirements

Maintain the SIMPLE IRA plan document (Form 5304-SIMPLE or 5305-SIMPLE), records of all contributions (employer and employee) with dates, salary deferral election forms from each employee, and annual summary reports. The plan must be established by October 1 of the year it takes effect (for existing employers). Retain records for at least 6 years — retirement plan records have extended retention requirements.
