This article is for admins who need to pay insurance carrier invoices and understand how benefit deductions work.
Once your benefits start, your insurance carrier(s) will send you monthly premium invoices for your company's coverage. Pay these invoices on time to keep your group plan active. Each carrier sends invoices monthly by mail or email. Contact your insurance carrier to update your billing preferences.
If employees contribute to their premiums, we deduct their share pre-tax from their paychecks (if you offer benefits through Gusto), or you can set up manual payroll deductions (if you offer benefits through a third party). These deductions stay in your company bank account. You can then pay the full premium amount to your carrier in one payment. Go to the How benefits deductions and premium payments work section of the article to learn more.
Health insurance carriers use two methods to determine premiums. Member-level rating uses each employee's personal details to set individual prices. Composite rating averages the price for all employees when you set up the plan and locks in that plan rate for the duration of the plan year.
Member-level rating
Carriers base rates on each employee's and dependent's age, zip code, and (in some states) smoking status. For small group insurance, carriers make these rates public, so we can tell you your exact premium before you enroll.
Composite rating
Carriers calculate the rates by averaging the rates of all participating employees. We cannot provide you with your exact premium until all employees complete open enrollment and submit their applications. The carrier then calculates the final composite rates. Once the carrier finishes, we'll tell you your premiums for the year.
In some states (like Massachusetts), carriers calculate four composite rates based on which family members enroll:
Employee only rate
Employee + spouse rate
Employee + child rate
Employee + family rate
In other states (like Washington), some carriers use just two composite rates. Each person's age determines which rate applies to them:
Over 21 years old rate
Under 21 years old rate
Questions and answers
Q: How much will the premium cost for a newly hired employee who enrolls mid-year?
A: For member-level rating, carriers calculate premiums using either the member's age and zip code on their start date or the group's start date (this varies by carrier).
For composite rating, carriers lock in rates for the year based on the group's average demographics at the start of the plan year. New hires pay those fixed rates until you renew your contract.
Q: When will I find out how much the premiums cost with a composite rating?
A: We'll tell you once the carrier sends us the final rate. This happens after your group completes open enrollment and before your start date.
The company contribution is the amount you contribute to your employees' insurance premiums. Your insurance carrier contract includes your company contribution, and you can only change it during your plan's annual renewal.
You can find your company's contribution in the Benefits section of your Gusto account.
Contribution requirements
If you offer benefits with Gusto, we make sure your company's benefits package meets all requirements, including minimum contribution requirements.
Carrier requirements: Your insurance carrier may require a minimum company contribution for employees (and sometimes dependents).
Federal requirements: If you have 50+ employees, your company likely must follow the Affordable Care Act's employer mandate, including the "Employer Responsibility" provision. Learn more from the IRS.
Once your benefits start, your carrier(s) will send premium invoices to your company. Pay these invoices by the due date to keep your group plan active.
If employees contribute to their premiums, we deduct their share pre-tax from their paychecks (if you offer benefits through Gusto), or you can set up manual payroll deductions (if you offer benefits through a third party). These deductions stay in your company bank account. You then pay the full premium amount to your carrier in one payment.


Premium deductions for owners paid by owner's draw
Owners' draws are pre-tax. This means the owner's draw paystubs do not show benefit deductions. The company pays the full cost of health benefits for owners.
Once you set up health insurance, your carrier will send you monthly invoices. Pay these invoices directly to your carrier by the due date to keep your coverage.
For carriers that allow it, we may set up automatic payments for you. If you connected your bank account using instant bank verification (IBV), we may send your carrier an electronic funds transfer (EFT) form using your tokenized account number (TAN). If your company bank account information changes, you must update it with your carriers directly.
Select your carrier from the list below for payment instructions.
If your carrier does not appear on this list, contact them directly for payment info. Once you set up your benefits with Gusto, you can find carrier contact info in the Benefits section of your account.

If you pay your insurance carrier by ACH direct deposit and your company's bank information changes, update your information directly with each insurance carrier. We do not send changes to your bank info in Gusto to the carriers. If you do not update your bank info with your carrier, your carrier may terminate your company's insurance for non-payment.
Insurance carriers typically generate invoices 15–30 days in advance of the due date. This means carriers usually take 1–2 billing cycles to remove a dismissed employee from your invoice.
If you see a dismissed employee on your invoice, pay the full invoice amount anyway. The carrier will credit you for the overpayment once they finish processing the termination.
Note: We cannot prorate deductions on payroll. For example, if you dismiss an employee on January 15 and their benefits continue through January 31, we will not capture the remaining deductions the employee owes for the second half of the month. To apply additional deductions, process the final pay as an off-cycle payroll, and select the option to apply them.
Contact us if the employee still appears on the invoice after more than two billing cycles. To contact us, sign in to your Gusto account and click the help icon
in the top-right corner of the page.
