Answer and Explanation:
1a .Account receivable $15,000
Less Account payable $18,000
=$3,000
Hence Erin would be required to make a IRC §481 adjustment in order to ensure that she does not omit receivables and payables from the taxable income under the accrual method of accounting in which she is switching to. Her net IRC§481 adjustment would be to decrease net income by $3,000 ($15,000 receivables minus the $18,000 payables) due to the fact that this is an income decreasing adjustment which would make Erin would deduct the full adjustment amount in year1
1.b.Account receivable $25,000
Less Account payable $9,000
=$16,000
Erin's net IRC §481 adjustment will be to increase net income by $16,000 ($25,000 receivables minus the$9,000 payables). Because it is a income increasing adjustment, therefore Erin would include 25 percent of the net adjustment ($4,000) in taxable income in each of the next four years starting with year 1.
