Under the write-off approach, the total under- or overallocated manufacturing overhead is included in this year’s Cost of Goods Sold expense. For Robinson, the journal entry would be as follows:

Cost of Goods Sold: 135,000 dollars
Manufacturing Overhead Allocated: 1,080,000 dollars
Manufacturing Overhead Control: 1,215,000 dollars
Robinson’s two Manufacturing Overhead accounts—Manufacturing Overhead Control and Manufacturing Overhead Allocated—are closed with the difference between them included in Cost of Goods Sold. The Cost of Goods Sold account after the write-off equals $2,510,000, the balance before the write-off of $2,375,000 plus the underallocated manufacturing overhead amount of $135,000. This results in operating income decreasing by $135,000.
