Six Steps For Every Payroll.
This checklist is our suggested process, not a legal requirement. The legal tests are on the other pages in this series. The aim here is to make the tests easy to meet and easy to prove.
Step one: at payroll close, run a deduction register by plan code and confirm the total ties to the benefits system’s billing file. Step two: move the withheld employee share to a designated account or ledger, so plan money is identifiable from the day it is withheld. Step three: set the release date for the carrier payment, shorter than both the invoice due date and the legal limit that applies to you, as discussed on the 90-day page.
Step four: have a second person approve the payment. Step five: when the carrier confirms receipt, save the confirmation with the register. Step six: at month end, reconcile the carrier bill to the deductions and the employer share, and investigate any difference before the next billing cycle. A late or short payment found in one month is far easier to repair than one found at year end.
Where The Process Usually Breaks.
Payroll and benefits administration often sit in different hands. New hires, terminations and mid-year changes in the benefits system must reach payroll in time for the next run, or the deduction and the bill drift apart. Our payroll integration guide explains how those systems exchange eligibility and deduction data.
Plan year changes are another weak point. New rates take effect on a date that rarely matches a pay period, and a deduction left at last year’s amount creates an underfunded month. Update deduction amounts before the first payroll of the new plan year and reconcile that month first.
Michigan adds one documentation point. The Payment of Wages and Fringe Benefits Act, MCL 408.477, generally allows deductions only where law or a collective bargaining agreement requires or permits them or the employee agrees freely in writing. Keep the signed deduction authorization with each election.
Setting It Up This Month.
Name an owner for the routine and a backup. Put the release date for each carrier on the payroll calendar.
Write the six steps on one page and have payroll, finance and HR initial it.
Test the routine on the next billing cycle and keep the register, approval and confirmation in one folder. If an outside service handles any step, ask it for its own written timing commitment.
Common Misreadings.
Assuming the carrier will tell you if a payment is late. Carriers bill on their own timeline, and by the time a notice arrives the gap may be weeks old.
Letting the benefits platform’s billing file stand in for the payroll register. They answer different questions, and the routine needs both.
Treating the routine as an HR task alone. The money moves through finance, so finance owns half of the controls.

Quick Answers.
Short replies on this page’s topic, each tied to a fuller guide.
How often should we remit employee contributions to the carrier?
The law sets outer limits and a reasonableness standard, not a single frequency. We suggest paying on a fixed schedule that is shorter than both the carrier’s due date and the limit that applies to your plan.
Who should approve the carrier payment?
We suggest someone other than the person who prepared it, with finance involved, so the control does not depend on one person. This is a process suggestion, not a legal requirement.
Do we need written authorization for payroll deductions in Michigan?
MCL 408.477 generally allows wage deductions only where law or a collective bargaining agreement requires or permits them or the employee agrees freely in writing. Confirm how it applies to your forms with counsel.
