KFF 2026 Employer Health Benefits Survey: Budget Each Client's Employer Share for 2027, Not the 9% Headline

The KFF 2026 Employer Health Benefits Survey, published October 22, 2026, reports that workers now pay 9% more toward family coverage, but the employer share of the average family premium rose about 3.4%. For a firm budgeting 2027 across dozens of clients, the number to budget is each client's employer share by month, not the headline.

Why this matters now

On 2026-10-22 KFF published the 2026 Employer Health Benefits Survey, the 28th edition of its annual benchmark, built from 1,937 non-federal public and private employers with ten or more workers interviewed between January and July 2026. The average annual premium for family coverage reached $28,303, up 5% or $1,310 from 2025. Workers' own contribution toward that premium reached $7,471, up 9% or $621. Over the same year wages grew 3.7% and inflation ran 2.7%. Single coverage averaged $9,804, also up 5%, with workers paying $1,672 of it. KFF's release the same day led with the worker figure, and so did the news coverage that followed.

Subtract one published number from the other and the employer side appears. A $28,303 family premium less a $7,471 worker contribution leaves $20,833 paid by the employer in 2026. Run the same subtraction on the 2025 figures, $26,993 less $6,850, and the employer paid $20,143. The employer share therefore rose $690, or 3.4%, in a year when the worker share rose 9% and the total rose 5%. That is the number that lands in a client's health insurance expense account, and it is the number almost nobody is quoting.

The forward-looking figure comes from Mercer. On 2026-08-31 Mercer published preliminary results from more than 1,800 employers in its 2026 National Survey of Employer-Sponsored Health Plans. Total health benefit cost per employee is expected to rise 8.2% in 2027, the largest increase since 2003, and employers said their current plans would cost 11% more if they took no action. Fifty-nine percent plan cost-cutting changes for 2027, including higher deductibles, and roughly two-thirds of employers with 500 or more employees expect to raise employee premium cost sharing. Rising GLP-1 use alone accounts for about one point of the growth. KFF's own summary notes that forecasts for 2027 are again approaching double digits.

For an accounting firm, the timing is the point. Fourth quarter is when client budgets get built, and renewal letters for January and March plan years are arriving now. Coverage of the survey is written for workers and for the policy debate, so it answers what a family pays. It does not say what goes in the client's 2027 budget, which month the step lands, or how to keep the worker share out of the expense line. The rest of this article is that answer, as a procedure the firm can run for every client that offers coverage.

What the survey says, read as a budget input

Three things in the table change how a firm budgets. First, the percentages diverge because the worker share grew faster than the total. Any budget that applies the 9% headline to a client's health insurance expense is reading the wrong line; the employer share grew 3.4% on average, and the client's own renewal letter will say what it grew for them. Second, the survey reports per covered worker, not per employee. At firms that offer coverage, 59% of workers actually enroll, so a budget built on headcount times premium overstates the line for every employee who waives. Third, small firms are already further along the cost-shifting path than large ones. At firms with fewer than 200 workers the average worker pays $9,687 toward family coverage, 37% of the premium, against $6,840 and 25% at large firms, and 32% of small-firm workers pay more than half of the family premium against 6% at large firms. The lever large employers are reaching for in 2027, a higher employee share, has less travel left at a 15-person client.

The accounting distinction underneath all of this is the one covered in the employee benefits accounting guide: the employer share of the premium is an expense, a flow through the P&L, while the employee share is withheld from pay and sits in a liability account until the carrier invoice is paid. Only the first number belongs in the budget's expense line. The second belongs in the payroll liability roll-forward, and a client whose books mix the two will show health insurance expense roughly a third too high at the family tier.

A worked example: one client, one renewal, two budgets

Ridgeline Plumbing has 24 employees and a fully insured plan that renews on March 1. Fifteen employees enroll, nine in single coverage and six in family coverage; nine waive. In 2026 the monthly rate is $750 for single and $2,200 for family. Ridgeline pays 80% of the single premium and 60% of the family premium, which puts a family enrollee's share at $880 a month, or $10,560 a year, close to the survey's $9,687 small-firm average. The numbers are illustrative; the method is what carries across clients.

Start from the client's own rates, not the survey

The 2026 monthly premium is $6,750 for the nine single enrollees and $13,200 for the six family enrollees, $19,950 in total. Ridgeline's share is $5,400 plus $7,920, or $13,320 a month, and the employees' share is $6,630. For the year that is $239,400 in premium, of which $159,840 is Ridgeline's expense and $79,560 is withheld from pay. The survey's job here is to sanity-check those splits and to set expectations for the renewal. The budget itself comes from the client's enrollment census and rate sheet.

Phase the renewal month

The carrier's renewal letter, due in December, is the real input. Until it arrives, Mercer's 11% no-action figure is a defensible placeholder for a client that has not yet decided on plan changes. At 11%, single goes to $832.50 and family to $2,442, and the total monthly premium rises from $19,950 to $22,144.50 on March 1. January and February stay at 2026 rates. A budget that applies the increase to all twelve months, $159,840 times 1.11, or $177,422, overstates the employer line by $2,930 and then produces a favorable variance in January and February that nobody asked for.

Scenario A: hold the 80/60 split

If Ridgeline keeps its contribution percentages, its monthly share from March is $5,994 on single plus $8,791.20 on family, $14,785.20. Two months at $13,320 and ten at $14,785.20 give a 2027 employer budget of $174,492, up $14,652 or 9.2% on 2026. Employee withholding rises to $7,359.30 a month from March, $86,853 for the year. The family enrollee's share goes from $880 to $976.80 a month.

Scenario B: move the split two points

If the owner moves to 78% single and 58% family, Ridgeline's monthly share from March is $5,844.15 plus $8,498.16, $14,342.31. The 2027 employer budget becomes $170,063, up $10,223 or 6.4%. Withholding rises to $7,802.19 a month from March, $91,282 for the year, and the family enrollee pays $1,025.64 a month, $12,308 a year, an increase of $1,748 or 16.6%. Because employee contributions run through a section 125 plan, the extra $4,429 of pre-tax withholding under Scenario B also trims Ridgeline's employer FICA by about $339 for the year. That is real but small, and it belongs in a footnote, not in the decision.

Put the two scenarios side by side and the owner sees what the survey is really describing: a 2.8-point difference in the employer's cost increase, bought with a 16.6% increase in what a family enrollee pays. The firm's job is to lay out that trade, not to make it.

The entries, and what stays off the P&L

Carriers bill in advance. When the March invoice for $22,144.50 arrives in late February, debit prepaid insurance and credit accounts payable; the asset sits on the balance sheet, a point-in-time amount, until the coverage month. On March 1, debit health insurance expense for Ridgeline's share, $14,785.20 under Scenario A, debit employee health contributions payable for the employees' $7,359.30, and credit prepaid insurance for the full invoice. Each payroll in March credits the same liability account as the employee share is withheld, so the account returns to zero by month end. If it does not, either the deduction rate on the payroll items is stale or someone posted the whole invoice to expense. The budget, the expense account, and the liability roll-forward are three views of one premium, and they should agree.

Accounting controls for the 2027 benefits budget

Source data: the client's current carrier rate sheet by tier; the enrollment census by tier with waivers; the employer contribution percentages or dollar amounts as written in the plan document and section 125 plan; the renewal letter when it arrives, with its effective date; the payroll register showing health deductions by employee; the carrier invoices; and the KFF and Mercer figures as external benchmarks, labeled as such.

Calculation: enrollment by tier times the monthly rate gives total premium; times the employer percentage gives the expense line; the remainder is withholding. Apply 2026 rates to months before the renewal date and renewal rates from the renewal month forward. Derive the employer share of the survey's averages the same way, premium less worker contribution, so the benchmark and the client figure are built identically. The variance between budget and actual splits into three parts, rate, enrollment, and tier mix, and the calculation should produce all three.

Review: a second preparer agrees the enrollment census to the carrier invoice, agrees the employee deduction amounts on the payroll register to the plan's percentages, confirms the renewal month in the budget matches the effective date on the renewal letter, confirms the employee share is budgeted to the liability account and not to expense, and checks that the prepaid insurance balance at any month end equals the next month's invoice and nothing else. For a firm running this across many clients, a one-page checklist per client with those five ticks is enough, and it is the same checklist every time.

Decision: the client's owner decides the contribution split and any plan design change, with the broker, and signs the renewal. The firm owns the budget mechanics, the benchmark comparison, and the explanation of what each scenario does to the employer line and to a family enrollee's paycheck. The payroll provider implements the deduction amounts it is given; it does not choose them. Write down who made the split decision and when, because that decision, not the carrier's rate, is what the variance explanation will come back to in April.

Limits and common mistakes

The survey covers firms with ten or more workers, so a client with six employees is outside its sample, and the small-firm averages it reports are weighted toward firms larger than many bookkeeping clients. Use its figures as context for the conversation, not as the client's rate.

Mercer's 8.2% and 11% are averages across employers of every size and funding type, reported before the client's own quote exists. Replace the placeholder with the renewal letter the day it arrives and re-run the budget. A placeholder that survives into the final budget is a forecast error waiting to be explained.

Self-funded clients do not budget premiums. They budget expected claims, stop-loss premiums, and administration fees, and the employer-versus-employee split works through the contribution rate rather than a carrier invoice. The same expense-versus-liability distinction holds, but the mechanics differ, and this article's example is the fully insured case.

Headcount times premium is the most common error. Only enrolled employees generate premium, and the tier mix moves the total more than headcount does; one family enrollment is worth nearly three single enrollments at Ridgeline's rates. Budget from the census.

Applying the survey's 9% to the expense line is the second most common error, and it comes from reading the headline rather than the table. The employer share rose 3.4% on average in 2026. The client's number will be whatever the renewal letter says, but it will not be the worker figure.

Finally, this is one line in a payroll budget that has several stepped items. The 2027 Social Security wage base article walks through the same month-by-month approach for employer payroll tax, where the step lands in January and reverses as high earners cap out. For a client with more than one entity, the health premium, the payroll tax, and the enrollment census all need to roll up the same way; the consolidated budget versus actuals guide covers how to keep the entity-level lines comparable.

Frequently Asked Questions

What did the KFF 2026 Employer Health Benefits Survey find?

KFF's 2026 survey, published October 22, 2026, found that the average annual premium for employer-sponsored family coverage reached $28,303, up 5% from 2025, while the average worker contribution toward that premium reached $7,471, up 9% or $621. Single coverage averaged $9,804 with workers paying $1,672. Wages grew 3.7% and inflation 2.7% over the same period. The survey covered 1,937 employers with ten or more workers.

How much did the employer share of health premiums rise in 2026?

Subtracting the worker contribution from the total premium in the KFF figures gives an employer share of $20,833 for family coverage in 2026, compared with $20,143 in 2025, an increase of $690 or about 3.4%. The employer share grew more slowly than the 5% total because workers absorbed a larger portion of the increase.

Should a small business budget health insurance from the survey averages?

No. Budget from the client's own enrollment census by coverage tier, its current carrier rates, its written contribution percentages, and the renewal letter when it arrives. Use the survey averages and the Mercer 2027 forecast as benchmarks for the conversation with the owner, and use a forecast figure only as a placeholder until the actual renewal quote replaces it.

Is the employee share of the premium an expense?

No. The employee share is withheld from pay and credited to a payroll liability account, then debited when the carrier invoice is applied, so it never passes through the income statement. Only the employer share is health insurance expense. Posting the whole carrier invoice to expense overstates the line and leaves the liability account with a balance that never clears.

How should the renewal month be handled in the 2027 budget?

Apply 2026 rates to the months before the renewal effective date and the renewal rates from that month forward. For a March 1 renewal, January and February stay at the old rates and March through December carry the new ones. Applying the increase to all twelve months overstates the budget and creates artificial favorable variances in the pre-renewal months.

A firm that builds this budget for forty clients wants the employer line, the withholding liability, and the enrollment count visible in one place, by client and by month, with the carrier invoice and payroll postings behind each figure.
