How do I lower my health insurance renewal without changing plans?

Four things lower what a renewal costs the company while the plan, the carrier and the broker stay where they are: a current census, a Section 125 premium-only plan, the premium split, and recovered payroll tax. The last one is worth up to $640 per enrolled employee per year.

What sets a small-group premium?

Four things about the group, by law, plus the plan you pick, for small-group coverage, which Healthcare Dive (August 7, 2026) describes as the market for employers with fewer than 50 employees. 42 U.S.C. §300gg (checked September 11, 2026) says a rate in the individual or small group market can vary only by whether the coverage is for an individual or a family, by rating area, by age, and by tobacco use. HealthCare.gov (checked September 11, 2026) says:

“Under the health care law, insurance companies can account for only 5 things when setting premiums.”

Age, where people live, tobacco use, individual or family enrollment, and plan category. The same page: “Your health, medical history, or sex can’t affect your premium.” Age can move a premium up to three times, and tobacco use up to 50%.

So the renewal on your desk was priced off a census, and the census is the first thing to check. Look for an employee who left in March, a dependent who aged out, and, in states that allow tobacco rating, a tobacco flag that stopped being true. Each one is a line on the bill that shouldn’t be there. Under 45 CFR §147.102 (checked September 11, 2026), the rating area for a small group is the group policyholder’s principal business address, so a move by one employee doesn’t change it. Checking the census takes an hour, and it’s the only move on this page that lowers the renewal number itself.

Does a Section 125 premium-only plan lower what the company pays?

Yes, by the company’s share of Social Security and Medicare tax on the dollars employees contribute, up to 7.65%. A premium-only plan is the simplest Section 125 cafeteria plan: employees pay their share of the premium before tax instead of after. The IRS (checked September 11, 2026) describes what that does to the tax on those dollars:

“Generally, qualified benefits under a cafeteria plan are not subject to FICA, FUTA, Medicare tax, or income tax withholding.”

Both sides save. Employees stop paying income tax and their half of Social Security and Medicare on the premium they contribute. The company stops paying its half on the same dollars, which the IRS (Topic 751, reviewed January 20, 2026) sets at 6.2% for Social Security on wages up to $184,500 in 2026 and 1.45% for Medicare on all wages. The plan, the carrier and the premium don’t change. If you already have one, it’s in your plan documents. If you don’t, setting one up takes a written plan and a payroll setting.

Does changing the premium split lower the renewal?

Moving the split lowers what the company pays. It doesn’t lower the renewal. The plan costs the same, a bigger share of it moves onto paychecks, and your people see it on the next check. KFF (October 22, 2025) reported workers paying $6,850 a year toward family coverage. Every point you move raises that. It’s the easiest move on a spreadsheet and the one your people feel first. How it compares with an ICHRA, a level-funded plan and a PEO is on its own page.

How much of a renewal increase can payroll tax savings offset?

Up to $640 per enrolled employee per year, and the group plan stays as it is. SIMERP, a self-insured medical expense reimbursement plan, redirects payroll tax the company is already paying into medical care for employees and their families, and that amount comes back to the company every year.

For a 40-person company where everyone enrolls, that’s up to $25,600 a year set against the increase. If the plan costs $20,000 a month, a 14% increase is $33,600 a year, and the recovery offsets about three quarters of it. If the plan costs $15,000 a month, the same increase is $25,200, and it’s offset in full. Whether yours is offset in part or in full depends on two numbers, the plan’s monthly cost and the percentage on the letter, and simerp.com/renewal puts them side by side.

Every enrolled employee, plus up to 6 legal dependents, gets urgent care around the clock, primary care appointments in days, mental health support from licensed clinicians, and over 1,000 medications at no cost, with no copay, deductible or fee. Take-home pay goes up. SIMERP isn’t insurance and doesn’t replace your plan.

Which move should you make first?

In this order, from the cheapest to do to the one that costs your people the most:

• The census, this week. An hour’s work, and the only move that lowers the renewal number itself.
• A premium-only plan, if the plan document doesn’t already say you have one. A written plan and a payroll setting, worth up to 7.65% of every dollar employees contribute.
• Recovered payroll tax, because it’s the only move on this page big enough to offset a 14% increase, the median insurers filed for 2027 small-group plans (KFF, reported by Healthcare Dive, August 7, 2026), and the only one that gives your people something.
• The split, last, and only for whatever is left, because it’s the one your people pay for.

If you want the numbers behind that 14% first, how much small-group premiums are going up for 2027 is on its own page.
