"We want to show to payment as a Prepaid Expense as of 12/31 and my Controller feels that we should also show state tax expense in December. However, the expense is currently showing in January with the Prepaid in December. I'd like some thoughts on this topic and also if any further JEs are needed."
Your question is a bit confusing. You can't have both an expense and a prepaid expense at the same time for the same payment, it's one or the other. Both are a debit entry from an accounting perspective. The way it is posted currently (prepaid in Dec. and expense in Jan.) sounds right. Am I missing something?
