You have been engaged to review the financial statements of Gottschalk Corporation. In the course of your examination, you conclude the bookkeeper hired is not doing a good job. You notice a number of irregularities as follows.

1. Year end wages payable of $3,400 were not recorded because the bookkeeper thought they were "immaterial."

2. Accrued vacation pay for the year of $31,100 were not recorded because the bookkeeper "never heard that you had to do it."

3. Insurance for a 12 month period was purchased on November 1st of this year was charged to insurance expense in the amount of $2,640 because "the amount of the check is about the same every year."

4. Reported sales revenue for the year is $2,120,000. This includes all sales taxes collected for the year. The sales tax rate is 6%. Because the sales tax is forwarded to the State's Department of Revenue, the Sales Tax Expense account is debited. The bookkeeper thought that "the sales tax was a selling expense." At the end of the current year, the balance in the Sales Tax Expense account is $103,400.

Prepare the necessary correcting entries, assuming Gottschalk Corporation uses a calendar-year basis. The books for the current year have not been closed.
