Answer:
Salaries and wages payable...................Dr $20,000
Salaries and wages expense $20,000
Explanation:
As per accrual system, an expense is incurred when it is accrued irrespective of when it is paid. So, $20,000 was accrued in December 31, salary and wages expenses would have been debited then amounting to $20,000.
In order to rectify the mistake of double counting, the entry passed by the accountant would be reversed to nullify the effect.
Adjusting Journal entry:
Particulars Debit Credit
Salaries and wages payable $20,000
Salaries and wages expense $20,000
(Being double counting of salaries and
wages expense rectified)
