This includes hobby operating expenses.<br/>3. Exception: Expenses deductible anyway (Mortgage interest, Property taxes) are still deductible on Schedule A.<br/>4. Net Effect: Income +$20,000. Deduction -$10,000 (Property Tax). Net +$10,000.

Full Answer

C.Increase of $10,000✓ Correct
C
The taxpayer must report the $20,000 gross income. The $40,000 operating expenses are miscellaneous itemized deductions, which are suspended under TCJA. The $10,000 property taxes are deductible on Schedule A (subject to SALT caps, assumed deductible here). Net impact: +$20,000 Income - $10,000 Deduction = +$10,000 increase in taxable income.

Common mistakes

Deducting hobby expenses up to the amount of hobby income (old rule) or forgetting that property taxes are still deductible.
