If a journal entry and posting for the use of one month of rent from the prepaid rent account during the year is accidently omitted, what would be the impact on the financial statements

Expenses will be understated, hence, Net Income will be overstated.

Rent prepaid will be overstated, hence, current assets will be overstated.

Explanation:

Ordinarily, rent prepaid is meant to be credited every month to the tune of the the value that has been consumed and then added to period expenses to reduce net income.

In the statement of Financial Position, the same amount that has been consumed should be used to reduce balance in rent prepaid account, otherwise, current assets will be overstated if no adjustment is made.
