This question tests MACRS depreciation for office furniture as tangible personal property under GDS with the half-year convention. The furniture is 7-year property costing $50,000, placed in service on July 1, 2025 (third quarter), without Section 179 or bonus depreciation. The correct deduction follows IRS guidelines using the 14.29% first-year rate, yielding $50,000 × 14.29% = $7,145. Choice B ($5,000) incorrectly applies a 10% rate, perhaps confusing with straight-line; choice C ($8,930) uses the 17.86% mid-quarter rate for third quarter; choice D ($3,575) halves the correct amount erroneously. For MACRS calculations, always determine the property's class life to select the recovery period, apply the convention, and use the corresponding percentage from IRS tables. This framework highlights the importance of matching the asset to its IRS-defined class life for compliant depreciation scheduling.

This question tests the application of the Modified Accelerated Cost Recovery System (MACRS) for depreciating tangible personal property using the General Depreciation System (GDS) with the half-year convention. The key facts are that the manufacturing equipment is 7-year property with a cost basis of $120,000, placed in service in the second quarter of 2025, and no elections for Section 179 or bonus depreciation. The correct answer aligns with IRS MACRS guidelines because the first-year depreciation rate for 7-year property under the half-year convention is 14.29%, resulting in $120,000 × 14.29% = $17,148. Choice A ($8,571) is incorrect as it represents half of the first-year amount, possibly a misapplication of the convention; choice C ($24,000) wrongly applies the 20% rate for 5-year property; choice D ($14,580) might stem from using an incorrect rate like 12.15%. To calculate MACRS depreciation generally, identify the asset's class life to determine the recovery period, then apply the appropriate convention and depreciation table percentages. Emphasizing proper selection of class life and recovery period ensures accurate deductions over the asset's useful life as per IRS rules.

The correct answer is Mid-quarter convention. The mid-quarter convention must be used if more than 40% of the total depreciable basis of personal property is placed in service during the last three months (the fourth quarter) of the tax year. First, calculate the total basis of property placed in service: $150,000 + $50,000 + $225,000 = $425,000. Next, determine the basis of property placed in service in the fourth quarter (October, November, December): $225,000. Finally, calculate the percentage: $225,000 / $425,000 = 52.9%. Since this is greater than 40%, the mid-quarter convention is required for all personal property placed in service during the year.

The correct answer is $7,140. The mid-quarter convention applies. The machine was placed in service in the fourth quarter. The first-year depreciation percentage for 7-year property placed in service in the fourth quarter is 3.57%. The calculation is: $200,000 (cost) * 3.57% = $7,140.

The correct answer is $7,500. Residential rental property is depreciated using the straight-line method over a 27.5-year recovery period with a mid-month convention. Since the property was placed in service in May, it is treated as being in service for 7.5 months during the first year (from the middle of May to the end of December). The calculation is: ($330,000 depreciable basis / 27.5 years) * (7.5 months / 12 months) = $12,000 per year * (7.5/12) = $7,500.

The correct answer is $43,750. Nonresidential real property is depreciated using the straight-line method over a 39-year recovery period with a mid-month convention. The building was placed in service in February, so it is treated as being in service for 10.5 months during the first year (from the middle of February to the end of December). The calculation is: ($1,950,000 depreciable basis / 39 years) * (10.5 months / 12 months) = $50,000 per year * (10.5/12) = $43,750.

The correct answer is $12,245. For MACRS, the depreciation in subsequent years is calculated by multiplying the original basis of the asset by the applicable percentage from the IRS tables for that year. The adjusted basis is not used in the calculation. The calculation is: $50,000 (original cost) * 24.49% (Year 2 percentage) = $12,245.

The correct answer is $20,000. A commercial warehouse is nonresidential real property, which is depreciated using the straight-line method over 39 years. While the first year's depreciation is prorated based on the month placed in service using the mid-month convention, any subsequent full year of service (like Year 3) receives a full year's straight-line depreciation. The calculation is: $780,000 depreciable basis / 39 years = $20,000.

The correct answer is $4,996. When personal property that was subject to the half-year convention is disposed of, the half-year convention is also applied in the year of disposition. This means the taxpayer is entitled to one-half of the depreciation that would have been allowed for a full year. The calculation is: $80,000 (original basis) * 12.49% (full year rate) * 1/2 = $4,996.

The correct answer is $3,600. When property subject to the mid-quarter convention is sold, the disposition is also treated as occurring at the midpoint of the quarter in which it is sold. First, calculate the depreciation for a full year: $30,000 * 19.20% = $5,760. The computer was originally Q1 property. It was sold in Q3 (August 1). For a Q1 asset sold in Q3, it is considered owned for 2.5 quarters. The depreciation is calculated as: $5,760 * (2.5 quarters / 4 quarters) = $3,600.
