How to accrued health insurance journal entries

Do you know for certain what the Bill is? (did you have any changes to the plan?)

Then just book the bill, and use Jul 2017 as the invoice/ref number. When the bill comes in, verify and file.

BTW, your entries are wrong...

If you get two month bills (I've never seen this), In June, July goes to pre-paid, June goes to expense. Then In July you move the pre-paid to expense.

Wayne - I don't know for certain, but it looks like Jenny's example was an accrual for June, then a reversal in July of the June accrual, then a recording of the actual invoice when it is received. If my guess is correct, then her example entries are OK, except that I would not accrue estimated expenses to Accounts Payable. I would use an Accrued Payable account. Accounts Payable should be balanced to actual vendor invoices recorded, but unpaid, at the closing date. Posting accruals to Accounts Payable breaks the direct tie between Accounts Payable and unpaid vendor invoices.

In my experience, health and dental insurance billing is almost always retrospective, rather than prospective, unless the company pays an annual premium, which is later adjusted to actual experience. If Jenny's company's insurance is retrospective, then the accrual account is correct. However, as you properly point out, if the premium is prospective, the a prepaid account is more correct.
