California’s small group market reaches 100 employees, and residents must consider the state coverage mandate. Cal-COBRA and San Francisco’s health spending ordinance add separate obligations. I would compare the actual provider network and employee costs, then check the local spending, continuation and coverage rules that apply to the business.

- **Regional rates:** 19 rating regions
- **Small group market:** Up to 100 full-time equivalents for CCSB
- **Budget examples:** Illustrative assumptions, not quotes
- **Compare before enrolling:** Network, payroll cost and continuation

## Small group eligibility and the resident mandate are separate

Covered California for Small Business generally serves employers with 100 or fewer full-time-equivalent employees, at least one qualifying W-2 employee and a majority of eligible employees living in California. Confirm all application conditions with the marketplace. A company between 51 and 100 employees should not assume a national broker’s default 50-employee market boundary applies in California.

California’s resident coverage mandate applies to individuals, with exemptions and household-specific calculations. For tax year 2025, the Franchise Tax Board identifies the flat amounts as $950 per adult and $475 per child, compared with the income-based calculation of 2.5% of gross income above the filing threshold, subject to the applicable rules and cap. These are 2025 tax figures, not a statement of the 2026 penalty.

I would not tell a new hire that every short gap necessarily produces a penalty. Have the worker review FTB’s exemptions and calculation. The employer should communicate the exact coverage effective date and any waiting period, so the person can evaluate coverage between jobs. Avoid assuming that a first-of-the-month start always leaves everyone continuously insured.

Use [Covered California’s application guidance](https://www.coveredca.com/small-business/apply) to confirm eligibility and documents. If the team includes out-of-state residents, verify both marketplace eligibility and the actual network available to those residents. A California policy classification does not prove that a remote employee has routine local access.

## San Francisco health spending reaches some workers outside the group plan

The city’s official 2026 HCSO poster states expenditure rates of $2.74 per hour for covered businesses with 20–99 workers worldwide and nonprofits with 50–99, and $4.11 for employers with 100 or more workers worldwide. Covered-worker conditions include at least eight hours of work per week in San Francisco and completion of 90 calendar days of employment. Exemptions and expenditure rules require separate review.

For illustration, 120 payable hours at the medium-employer rate produces $328.80 of required spending before considering any applicable exemptions or adjustments. That is 120 × $2.74, not a health insurance premium quote. Have payroll apply the ordinance’s hours rules and the city’s accepted expenditure methodology to the actual worker. Do not compare an annual company-wide benefits total with an individual hourly requirement.

An employee who declines your insurance may still need attention under HCSO. Ask whether a valid exemption or city-compliant waiver applies and what qualifying expenditure will be made otherwise. A standard insurance declination is not enough to establish the city result. Keep the worker-level spending records, required notices and reporting responsibilities together so the benefits administrator and payroll are using the same facts.

For a business hiring its first San Francisco-based remote employee, check where the person actually works and the employer’s worldwide size. Do not use the number of people enrolled in insurance as the city’s employer count. The [official 2026 poster](https://media.api.sf.gov/documents/2026_HCSO_Poster_Dec2025.pdf) is a useful starting point, followed by OLSE guidance for the detailed calculation.

## Cal-COBRA is an insured-coverage rule with eligibility conditions

California DMHC describes Cal-COBRA for eligible coverage at employers with 2–19 employees, for up to 36 months. Eligible people exhausting an 18-month federal COBRA period may obtain another 18 months through Cal-COBRA, reaching 36 months in total. Do not promise that extension for every employer arrangement: self-funded plans and other excluded coverage need separate treatment.

Ask the insurer to identify the applicable qualifying event, notice and election requirements, premium and early-ending conditions. The continuation premium is not the employee’s old payroll deduction. When replacing coverage, confirm how continuing beneficiaries transfer and what notice they receive. A departing employee should compare continuation with individual coverage while the loss-of-coverage enrollment opportunity is still available.

## The 2026 fertility rule distinguishes required coverage from required offers

DMHC’s implementation letter, revised February 23, 2026, explains SB 729 as amended. For covered contracts issued, amended or renewed on or after January 1, 2026, large group coverage must include the specified infertility and fertility benefits, while small group plans must offer the coverage. A small employer should ask whether it actually purchased that benefit. The law contains exceptions, including treatment of religious employers and a later date for CalPERS contracts, and does not impose its insurance mandate on every self-funded plan.

Get the benefit provision and authorization rules before telling employees that IVF is included. Ask which services, providers, medications and cost sharing apply. The legal duty to offer a benefit and an employee’s entitlement under the purchased policy are different questions. An employee planning treatment needs the written policy answer, not a general statement that California passed a fertility law.

## Count employees before comparing quotes

I separate three questions: whether the business can buy a small group policy, who is eligible to enroll, and whether federal employer responsibility applies. Those questions can use different counting rules. Send the broker a workforce census and the prior year’s payroll totals, including part-time staff and related businesses. Ask for a written explanation of the market classification. The number of people who accept insurance is not a substitute for the employer count.

Under the IRS rules, an applicable large employer generally averaged at least 50 full-time employees, including full-time equivalents, in the preceding calendar year. Related employers may need to aggregate their workforces, and a seasonal-worker exception can apply. This determines whether the employer shared responsibility provisions apply; it does not mean every business with 50 names on one payroll must immediately buy a particular policy. Use the [ALE calculator](https://www.getprescience.com/tools/ale-calculator) as a starting point and have payroll review the underlying hours.

For SHOP, HealthCare.gov requires at least one qualifying employee other than owners and specified family members. A company consisting only of founders should resolve eligibility before asking for prices. Do not label a contractor an employee merely to create a group. Give the carrier the actual ownership and employment facts, and ask which documents it needs. Participation and contribution requirements also need written confirmation for the specific product and enrollment date.

## Choose the arrangement around the work you need done

**A practical benefits decision table**

| Option | When I would consider it | What to resolve first |
| --- | --- | --- |
| Fully insured group coverage | A common employer benefit with a defined insurer contract. | Exact network, covered services, contribution policy and renewal terms. |
| Individual coverage HRA (ICHRA) | A defined employer allowance toward qualifying individual coverage. | Plans at every home address, subsidy effects, employee classes and administration. |
| PEO benefits offer | The business also wants the employment services in the PEO contract. | All service fees, benefits eligibility, cancellation terms and the replacement plan if you leave. |
| Other group proposals | The written terms address an identified problem with the current offer. | Who owes payments, maximum employer obligations, exclusions and obligations after termination. |

I would not choose an arrangement from its headline monthly price. Request the full agreement and a benefits summary. For a PEO, separate the insurance charge from the services contract and establish what happens to coverage when the relationship ends. For any proposal with employer claims obligations, ask for a maximum-cost illustration, renewal provisions and treatment of claims submitted after the contract ends. These are due-diligence questions, not a prediction that one approach will save money.

An ICHRA requires qualifying individual coverage or Medicare and has rules for employee classes and notices. An employee offered an affordable ICHRA generally cannot receive a Marketplace premium tax credit. If the offer is unaffordable, opting out may allow a credit if the employee otherwise qualifies. Do not add a projected subsidy to the allowance as though both were automatically available. Compare the employee’s remaining premium and care costs using the actual individual policy and household circumstances.

Ask the tax adviser to screen the small business health care tax credit before budgeting it. It generally requires fewer than 25 full-time equivalents, wages below the applicable tax-year limit and a qualifying employer contribution. The maximum is generally 50% of eligible premiums for taxable employers or 35% for eligible tax-exempt employers, over a two-consecutive-tax-year credit period. SHOP is generally required, but the IRS instructions contain limited exceptions where SHOP coverage is unavailable. A credit is not automatic just because a plan is called small business coverage.

## An illustrative San Francisco benefits budget

**Twelve employees with two coverage tiers**

This is an illustrative California planning exercise, not a carrier quote, survey average or forecast. Assume eight employees choose employee-only coverage at $700 monthly and four choose family coverage at $1,900. The employer pays 80% of both tiers. Fees, tax effects and medical spending are excluded.

- Employee-only premiums: 8 × $700 = $5,600 monthly
- Family premiums: 4 × $1,900 = $7,600 monthly
- Total premiums: $13,200 monthly; $158,400 annually
- Employer contribution, 80%: $10,560 monthly; $126,720 annually
- Employees collectively pay, 20%: $2,640 monthly; $31,680 annually
- Individual monthly payroll contribution: $140 employee-only; $380 family

The employer budget and employee contributions reconcile to the total premium. Replace every premium input with the written quote and rerun the calculation when the enrolled roster changes.

Now test an assumed 10% premium increase with the same people and benefits. Total premiums become $14,520 monthly. Maintaining the 80% contribution raises the employer cost to $11,616 and the combined employee cost to $2,904. Freezing the employer contribution at $10,560 instead leaves employees paying $3,960, a 50% increase in their combined contribution. Neither scenario is a prediction. It shows why a renewal percentage alone does not explain the impact on paychecks.

Build a second worksheet for each household’s care exposure. Record annual payroll contributions, the deductible, visit copays, prescription costs and the in-network out-of-pocket maximum. Premiums are separate from that maximum, and out-of-network or excluded services may add costs outside it. Have the insurer explain which expenses count. Compare the same services under each offer; a lower deductible alone does not establish that the entire plan is less expensive.

## Check care access where your California team lives

A San Francisco office address does not tell you where the team receives care. Map home ZIP codes, regular work locations and out-of-state dependents before choosing a network. Give employees a private way to identify important doctors and prescriptions. The employer needs enough information to compare access without collecting diagnoses in a shared enrollment spreadsheet. A carrier logo alone is not a network confirmation.

- Verify the exact product and network name with both the insurer and the provider. Include the physician’s location, medical group and facility, because a directory entry for one location may not answer the question for another.
- Ask how routine care works away from home. Emergency coverage does not establish access to an ordinary follow-up appointment for a remote employee or a child at college.
- Check the precise drug, dose and formulation on the formulary. Record the tier, required pharmacy, prior authorization and any step-therapy requirements before comparing prescription copays.
- For ongoing treatment, ask whether transition-of-care arrangements are available, how to request them and whether existing authorizations transfer. Do not promise that every current provider will remain covered.
- Save dated answers and reference numbers. Give employees an escalation contact for conflicting directory information and a process for reporting an enrollment problem.

I would test a routine appointment, a specialist visit and a prescription refill against each finalist. Ask what happens if no participating provider can offer an appointment within a reasonable distance or time. Get the plan’s process for arranging access rather than assuming the employee can use any doctor at in-network rates. Those checks make a comparison useful for employees whose needs differ from the person selecting the plan.

## Launch the plan with a calendar and an accepted roster

1. **Prepare the quote request** Use one census and effective date for all proposals. Include coverage tiers, locations and waivers. Have the broker identify missing eligibility evidence before employees start making elections.
2. **Set the contribution policy** Show employer and employee costs for every tier. Ask the administrator to review eligibility and contribution rules, including any proposed differences between employee groups. Identify payroll deductions and any separate service charges.
3. **Distribute the enrollment packet** Give employees the Summary of Benefits and Coverage, network details, payroll costs, enrollment deadline and a private contact for questions. Explain how they can decline coverage and document their election.
4. **Confirm the start date** Get written acceptance, the effective date, payment instructions and the accepted enrollment roster. Reconcile missing spouses, children and new hires before ending existing coverage. Do not equate an application submission with confirmed insurance.
5. **Audit the first invoice** Match insurer billing to accepted elections and payroll deductions. Track corrections until the insurer confirms them. Keep a record of who owns enrollment, notices, billing and employee support after launch.

Start several weeks before the proposed effective date as a planning choice, then work backward from the carrier’s actual deadlines. Federal waiting-period rules generally prohibit a wait exceeding 90 days after someone is otherwise eligible. A rule that starts coverage on the first of the month after 90 days can exceed that limit. Ask the administrator to test real hire dates, including month-end hires, rather than relying on a short handbook phrase.

At renewal, keep the census constant for the first comparison so you can distinguish a rate change from hiring, dependent additions or a new contribution policy. Ask whether accumulated deductibles receive credit when switching midyear and obtain the answer in writing. Send employees a clear explanation of the effective date and any new identification cards, pharmacies or referral procedures. Reconcile the old policy’s final invoice as carefully as the new policy’s first one.

## Handle departures, Medicare and family changes separately

Federal COBRA generally covers private-sector group health plans of employers with at least 20 employees on more than half of the prior year’s typical business days. Part-time workers count fractionally. Termination other than gross misconduct or a reduction in hours generally supports up to 18 months; other events and extensions can change the period. The usual premium ceiling is 102% of total plan cost, not 102% of the employee’s former payroll deduction. Government and church arrangements require separate scope review.

Give a departing employee the actual coverage end date, the continuation administrator’s contact and the complete premium. Loss of qualifying job-based coverage generally creates a Marketplace special enrollment opportunity during the 60 days before or after the loss. The employee should compare effective dates, networks and accumulated deductibles promptly. Voluntarily dropping continuation later generally does not create another special enrollment period by itself. Do not tell someone to wait for the continuation packet before investigating replacement coverage.

Medicare coordination depends on why the person qualifies for Medicare, current employment, employer size and sometimes multiemployer-plan rules. For age-based Medicare with current-employment coverage, Medicare generally pays first below 20 employees and the group plan generally pays first at 20 or more. Disability and end-stage renal disease use different rules. Have the employee confirm enrollment timing and payment order with Medicare and the plan; a blanket instruction to delay Part B can create a costly gap.

Marriage, birth, adoption, reduced hours and a dependent moving away can require different enrollment actions. Tell employees where to report a change and ask the administrator for the applicable deadlines. A payroll update alone does not update an insurer’s membership file. For leave, determine whether federal or state protections require continued benefits before processing the worker as a termination. State continuation also depends on the policy’s jurisdiction and funding, so the headquarters address cannot answer every case.

## California: a local procedure price and estimate checklist

Public self-pay examples help identify questions for a provider. They are not negotiated insurance rates, state market averages, comparable prices across states or estimates of insured out-of-pocket spending. Confirm a current written total before booking; a published amount is not a guarantee.

**California public local MRI pricing evidence (USD); limitations apply**

| Provider / primary source | Procedure | Published cash price / availability | Includes, excludes and unknowns | Effective date / status |
| --- | --- | --- | --- | --- |
| [Imaging Healthcare Specialists, San Diego County](https://www.imaginghealthcare.com/pricing/) | MRI without contrast | $400 cash | Single procedure; excludes breast and prostate MRI. Reading-fee inclusion is not clearly itemized. | Undated; no effective date stated. |

Pay in full at the appointment; the provider does not bill insurance for self-pay services. Personal-injury liens are ineligible. Confirm the exact scanner location and ordered study; the group price is not tied to a named site.

What to ask for an all-in written estimate:

- Which exact facility, procedure or CPT, body part and contrast protocol does the estimate cover?
- Does the total include the scan, facility charge and radiologist interpretation? Itemize contrast, sedation, labs and any other separate bills.
- Am I eligible for this self-pay offer, when is payment due, and how long is the written price valid? What changes could increase the total?
- If using insurance instead, ask the plan about network status, authorization and a separate benefit-based estimate. Ask whether a self-pay purchase receives any deductible credit; do not assume it does.

Employer ZIP code determines the region; check the detailed ZIP list on [rate-book page 4](https://www.blueshieldca.com/content/dam/bsca/en/broker/docs/2026/small-business/A46124GRP-2026Q4-SmallBusinessRateBook.pdf#page=4). Los Angeles spans two regions. The [carrier rate index](https://www.blueshieldca.com/en/employer/resources/rates) identifies the October–December 2026 rating period. Optional assisted-reproduction supplements are excluded. This same-plan illustration is not a market average, cheapest-plan claim or year-round rate. Payroll deductions depend on employer contributions; employee-only covers one adult without dependents.

I would compare the written Prescience offer with the same census, contribution policy and provider checklist used for other options. Your company can keep its payroll provider, and the plan can start midyear. A local group policy may be the better fit if it meets the team’s provider needs and budget. An individual coverage allowance may fit employees who prefer individual policies and understand the enrollment work. Make the decision from the actual benefits and terms available to your company.

## Frequently asked questions

**What is the flat California coverage penalty for tax year 2025?**

FTB lists $950 per adult and $475 per child. The income-based calculation, exemptions, coverage months and cap also matter. These figures should not be relabeled as the 2026 penalty.

**Does every California small group policy automatically include IVF?**

No. The applicable 2026 law requires small group plans to offer the specified coverage. Confirm that the employer purchased it and check the policy’s benefits, authorization rules and applicable exceptions.

**Does declining the company plan remove San Francisco HCSO obligations?**

Not automatically. Check the city’s covered-worker rules, exemptions, valid waiver requirements and qualifying expenditures. An ordinary insurance declination does not establish an HCSO exemption.

**Are the budget examples actual insurance prices?**

No. The premiums and renewal percentage are illustrative assumptions, not observed state averages, vendor prices or quotes. Replace them with written offers for the same enrolled population and start date.

**Does the small group definition determine whether the ACA employer rules apply?**

No. Market eligibility and federal applicable large employer status need separate review. The IRS generally uses the preceding year’s average of full-time employees plus full-time equivalents and aggregates certain related employers.

**Can I compare plans using only the monthly premium?**

Include payroll deductions, cost sharing, networks, prescription coverage and any separate fees. A low premium can leave more cost with employees when they receive care.

**Can an ICHRA employee also receive a Marketplace subsidy?**

An affordable ICHRA offer generally prevents a premium tax credit. An employee with an unaffordable offer may qualify after opting out, if otherwise eligible. Have the Marketplace assess the employee’s circumstances.

**How should a remote employee check the network?**

Confirm the exact plan, provider location, facility and routine-care access near the home address. A national insurance brand or emergency benefit does not by itself establish a local network.

**Can we start coverage in the middle of the year?**

Group coverage may start midyear subject to the insurer’s enrollment requirements. Confirm the effective date, accepted roster and any deductible credit before cancelling existing coverage.

**What should employees do when job-based coverage ends?**

Review continuation and replacement coverage at the same time. Loss of qualifying coverage generally supports a Marketplace special enrollment period, but election and payment deadlines differ between programs.

**What should an employee approaching Medicare eligibility do?**

Confirm Medicare enrollment timing and which coverage pays first. Age-based coverage, disability, end-stage renal disease and multiemployer coverage can produce different answers.
