Answer:
$85,000
Explanation:
First, we can organize the expenses information like this:
Expense Payment Date
Rental of Coliseum $25,000 12-21-2018
Cost of goods sold $90,000 12-30-2018
Performers $100,000 1-05-2019
Cleaning the coliseum $10,000 2-01-2019
Because in accrual basis of accounting, expenses are recognized when they are incurred, we then take the gross recepits, and substract from it all the expenses that were incurred in the year 2018.
That is to say, we substract all expenses except the cleaning the coliseum expense, because this expense was incurred in 2019, and was paid in 2019, therefore, it is not part of the taxable income for 2018 under the accrual basis of accounting.
Same is true for the performers expense. It was paid in 2019, but it was incurred in 2018, therefore, it has to be substracted to obtain the 2018 taxable income.
Taxable income = Gross receipts - Expenses incurred in 2018
= $300,000 - $215,0000
= $85,000
