What Is a QSEHRA?

A Qualified Small Employer Health Reimbursement Arrangement (QSEHRA) is a tax-favored benefit that allows eligible employers with fewer than 50 full-time employees to reimburse employees (including themselves, if owner-employees qualify) for individual health insurance premiums and certain out-of-pocket medical expenses on a pre-tax basis.

Key points about QSEHRA:

• Eligibility: Employers must have fewer than 50 full-time equivalent employees and no group health plan.
• Contribution limits: For 2025, the monthly maximum reimbursement is $615 for self-only coverage and $1,247 for family coverage (subject to annual IRS inflation adjustments).
• Tax treatment: Reimbursements are 100% deductible for the business and completely tax-free to the recipient, as long as expenses meet IRS criteria.
• Flexibility: Employers set a monthly allowance and employees choose their own health plan.

This arrangement delivers two core benefits:

1. Predictable employer cost: You cap your monthly benefit, offering budgeting certainty.
2. Employee empowerment: Each recipient selects coverage that best fits their needs, avoiding “one-size-fits-none” group rates.

By establishing a QSEHRA, you effectively convert individually purchased health plan costs—typically paid with after-tax dollars—into fully deductible, pre-tax reimbursements.

What Is a Solo 401(k)?

A Solo 401(k), also known as an Individual or One-Participant 401(k), is a retirement plan designed specifically for self-employed individuals or business owners with no employees other than a spouse. It mirrors the structure of a traditional 401(k) but with higher contribution potential and simplified administration.

Solo 401(k) highlights:

• Contribution limits (2025):
  • Employee deferral: Up to $23,000 (under age 50) or $30,500 (50 and over) as salary-deferral contributions.
  • Employer profit-sharing: Up to 25% of net self-employment income.
  • Total cap: Combined contributions cannot exceed $69,000 (under 50) or $76,500 (50+) annually.
• Tax advantages:
  • Traditional: Pre-tax contributions reduce current taxable income.
  • Roth option: After-tax contributions grow tax-free.
• Loan feature: You can borrow up to 50% of the account value (max $50,000).
• No discrimination testing: Since there are no rank-and-file employees (aside from a spouse), you avoid nondiscrimination hurdles.

A Solo 401(k) offers unmatched contribution flexibility, especially for high-earning entrepreneurs aiming to turbocharge retirement reserves while reducing AGI.

QSEHRA vs. Solo 401(k): A Side-by-Side Comparison

Feature	QSEHRA	Solo 401(k)
Primary Benefit	Health insurance premium & medical expense reimbursement	Retirement savings & tax deferral
Eligibility	Employers & employees (including owner) in firms <50 FTEs, no group plan	Self-employed individuals or business owners with no employees (except spouse)
2025 Contribution Limit	$615/mo self-only; $1,247/mo family	$69,000 (<50) / $76,500 (50+) total annual limit
Tax Deduction	100% of reimbursements	Traditional contributions reduce taxable income; Roth contributions tax-free growth
Distribution Rules	N/A (reimbursements are current expenses)	Underlying plan rules (59½+; 10% penalty for early withdrawal)
Administration	Simple plan document, run by employer	IRS Form 5500-EZ when assets > $250k; basic plan document
Other Features	No COBRA, no fiduciary testing	Loan option, Roth feature, high deferral limits

This table highlights how each program fills a distinct need: health cost coverage (QSEHRA) vs. maximum retirement savings (Solo 401(k)).

Why Combine QSEHRA + Solo 401(k)?

At first glance, QSEHRA and Solo 401(k) operate in separate silos—one covers medical expenses, the other retirement savings. However, their tax mechanics are synergistic:

1. Lower Adjusted Gross Income (AGI)
   • Solo 401(k) salary-deferral and employer contributions cut AGI directly.
   • A lower AGI can reduce Medicare premiums, IRA phase-outs, and certain income-linked Medicare taxes.
2. Maximized Pre-Tax Benefits
   • QSEHRA reimburses health expenses that would otherwise be out-of-pocket.
   • Solo 401(k) shifts more income into pre-tax savings.
3. Compound Tax Savings
   • Each dollar avoided in taxable income saves you your marginal tax rate (federal + state), often 24–37%.
   • Reimbursed health costs avoid payroll taxes (Social Security & Medicare) entirely.
4. Streamlined Compliance
   • Both plans require modest paperwork—QSEHRA has a simple plan document; Solo 401(k) only needs IRS Form 5500-EZ if assets exceed $250k.

Together, they create a robust tax-efficient package that addresses the two biggest self-employed burdens: personal health insurance and retirement security.

Step-by-Step: Setting Up and Implementing QSEHRA + Solo 401(k)

Follow these actionable steps to harness both strategies in the same tax year:

1. Confirm Eligibility
   • Ensure you have no group health plan and fewer than 50 FTEs to qualify for QSEHRA.
   • Confirm no employees (other than spouse) to deploy a Solo 401(k).
2. Establish the QSEHRA Plan
   • Draft a QSEHRA plan document (template providers include Gusto, Justworks, or your CPA).
   • Set monthly reimbursement allowances within IRS limits.
   • Provide written notice to all eligible employees 90 days before plan year (§9831(d)(1)).
3. Choose Your Health Insurance
   • Each participant selects an individual or family plan on the Marketplace or off-exchange.
   • Submit monthly premium invoices to employer for reimbursement.
4. Open Solo 401(k) Account
   • Select a custodian (Vanguard, Fidelity, Schwab, etc.).
   • Adopt the one-participant plan document.
   • Obtain an Employer Identification Number (EIN) for plan.
5. Maximize Contributions
   • Before December 31, decide on salary-deferral vs. Roth/traditional mix.
   • Estimate net self-employment income after health reimbursements.
   • Fund employee deferrals by payroll or quarterly estimated dates.
   • Make employer profit-sharing contributions by tax-filing deadline (including extensions).
6. Maintain Records
   • Track monthly reimbursements and retain receipts.
   • Document Solo 401(k) deposits and prepare Form 5500-EZ if necessary.
7. Year-End Tax Planning
   • Review AGI reductions and corresponding tax brackets.
   • Consider bumping QSEHRA allowance the following year if unused funds remain.

Real-World Tax Savings Example

Let’s walk through a hypothetical scenario to illustrate how a self-employed consultant named Alex can save over $10,000 in taxes by combining QSEHRA and Solo 401(k).

Item	Without Plans	With QSEHRA + Solo 401(k)
Gross Self-Employment Income	$150,000	$150,000
QSEHRA Reimbursement (self-only)	$0	$7,380 (12 months × $615)
Solo 401(k) Employee Deferral	$0	$23,000
Solo 401(k) Employer Contribution (25%)	$0	$31,155 (25% of $124,620***)
Taxable Income Before Deductions	$150,000	$150,000
Above-the-Line Deductions	$0	$61,535 total ($7,380 + $23,000 + $31,155)
Adjusted Gross Income (AGI)	$150,000	$88,465
Marginal Tax Rate	24% (Federal)	24%
Estimated Tax Savings	—	$61,535 × 24% = $14,768

* After QSEHRA reimbursement, net self-employment income used for employer contribution calculations is $150,000 − $7,380 = $142,620. Self-employment tax deduction (50%) further reduces the base, approximately to $124,620.

Breakdown of Savings:

• QSEHRA: $7,380 reimbursed tax-free rather than paid out-of-pocket (saves Alex 24% × $7,380 = $1,771 in federal income tax plus avoidance of 15.3% payroll taxes on that amount).
• Solo 401(k): $54,155 total contributions reducing AGI, saving 24% × $54,155 = $12,997.

Combined federal tax savings exceed $14,700. Add state income tax reductions (varies by state) and payroll tax savings, and yearly benefits top $10,000 with room to grow as income rises.

Key Considerations & Common Pitfalls

While the QSEHRA + Solo 401(k) combo is powerful, watch for these traps:

1. Plan Notifications
   • Missing the 90-day notice for QSEHRA participants can trigger penalties.
2. Excess Reimbursements
   • Reimbursements above IRS limits count as taxable income plus penalties.
3. Contribution Deadlines
   • Solo 401(k) employer contributions can be made up until your tax-filing deadline (including extensions), but employee deferrals must occur by year end.
4. Coordination with Other Plans
   • If you or your spouse participate in another employer’s plan, deferral limits are aggregated.
5. Recordkeeping
   • Document all reimbursements, plan amendments, and 401(k) transactions.

Pro Tip: Partner with a CPA or recordkeeper experienced in small-business benefits. A one-hour annual review can prevent costly missteps.

Frequently Asked Questions (FAQs)

Q1. Can I use QSEHRA to reimburse premiums for my spouse?
Yes—family coverage up to the per-family limit can be reimbursed, provided you enroll in an individual or family plan under your own name.

Q2. What if I have minor employees but still want a Solo 401(k)?
Any non-spouse employee disqualifies you from a Solo 401(k). Instead, consider a SEP IRA, though contribution flexibility is lower.

Q3. Can I switch my health plan mid-year?
Only if you experience a qualifying life event (marriage, birth, loss of coverage). Otherwise, reimbursements must align with plan’s coverage period.

Q4. Are reimbursements subject to payroll taxes?
No. QSEHRA reimbursements are exempt from employer and employee FICA taxes when handled correctly.
