The Small Business Health Care Tax Credit: The Most Overlooked Credit in the Code

 

Ask most small business owners if there's a tax credit for offering health insurance, and the honest answer is usually "I didn't know that existed." Section 45R has been on the books since 2010, and it remains one of the least-claimed credits available to small employers, largely because of a marketplace requirement that trips people up, and a phaseout formula that makes many assume they don't qualify when they actually do.

 

Here's how it actually works, and who it's really for.

 

What the Credit Covers

 

Section 45R provides a credit worth up to 50% of the premiums a taxable employer pays toward employee health insurance (35% for tax-exempt organizations), provided the coverage is purchased through the SHOP Marketplace (Small Business Health Options Program).

 

The credit is only available for two consecutive taxable years,  the two-year "credit period" begins with the first year the employer claims it. It's calculated and claimed on Form 8941, filed with the business return (or Form 990-T for tax-exempt organizations).

 

Who Actually Qualifies

 

To be an eligible small employer, the business must:

 

• Have fewer than 25 full-time-equivalent employees (FTEs) for the tax year, and

• Have average annual wages below a set threshold, for 2026, that threshold is $34,100 (indexed annually for inflation), and

• Pay premiums under a qualifying arrangement: a uniform percentage, not less than 50%, of the premium cost for each employee's coverage.

 

The full 50% (or 35%) credit is only available to employers with 10 or fewer FTEs and average annual wages at or below the threshold. Above that, the credit phases out gradually, completely eliminated once FTEs reach 25 or average wages reach twice the threshold ($68,200 for 2026). The phaseout is calculated using two separate fractions (one for FTE count, one for wages), so an employer doesn't need to hit both limits to lose the credit entirely, either one maxing out zeroes it out.

 

Who doesn't count as an employee for this credit: sole proprietors, partners, more than 2% S corp shareholders, more than 5% owners of other entity types, and family members of those owners. This matters, a lot of very small businesses are effectively owner and a couple of employees, and the owner's own coverage never factors into the calculation.

 

Why This Credit Gets Missed

 

1. The SHOP Marketplace requirement. Since 2014, the credit has only been available for coverage purchased through a SHOP exchange, not just any small-group health plan. Employers who already have coverage through a broker or a direct carrier relationship often don't realize their plan needs to run through SHOP to qualify, or don't realize SHOP is still an option in their state.

 

2. The two-year limit discourages people from checking. Because the credit period is only two consecutive years, business owners who looked into it years ago and didn't qualify (or forgot to elect it) often assume the window is permanently closed. It isn't,  the two-year clock only starts once you actually claim the credit, so a business that's never claimed it still has the full period available.

 

3. The phaseout math looks worse than it is. A lot of advisors mentally round the eligibility test to "under 25 employees" and stop there, missing that the wage threshold and the FTE count both drive a real, calculable partial credit, not just an all or nothing outcome.

 

The Planning Angle

 

This credit is worth raising with any small business client who:

 

• Currently pays a meaningful share of employee health premiums,

• Has fewer than 25 FTEs, particularly closer to 10 or fewer, and

• Hasn't already used up the two-year credit period.

 

It pairs naturally with a broader conversation about employee benefits strategy, the same client conversation that touches on the retirement plan startup credit is often the right moment to check whether health coverage is structured to capture this one too. For a business with modest premium costs and a handful of employees, this credit can meaningfully offset what the business is already paying, with no change in the coverage itself required, only where and how it's purchased.
