1. For tax purposes, a 4-unit apartment building purchased in 1992 must be depreciated using which of the following depreciation methods?

Answer: A

Explanation:

The 4-unit apartment building must be depreciated using the straight-line method.

For tax purposes, the straight-line method is the required depreciation method for residential rental property, such as a 4-unit apartment building purchased in 1992. This method allows for a consistent deduction over the asset's useful life.

A) straight-line

This option is correct because the straight-line method is mandated for residential rental properties placed in service after 1986. It spreads the cost of the property evenly over its useful life, which is typically 27.5 years for residential buildings.

B) variable

Variable depreciation is not a standard method recognized by tax regulations for real estate. This method implies fluctuating depreciation amounts, which does not align with the tax guidelines for residential properties.

C) accelerated

While accelerated depreciation methods exist, they are not applicable to residential rental properties purchased after 1986. The IRS specifically requires the straight-line method for such properties to ensure uniformity in tax reporting.

D) passive

Passive is not a depreciation method but rather a classification of income or activity type under the IRS rules. Therefore, it cannot be used to determine how to depreciate a property for tax purposes.

Conclusion

The straight-line method is the definitive choice for depreciating a 4-unit apartment building purchased in 1992, as it complies with the IRS regulations for residential rental properties. All other options fail to meet the requirements set forth by tax laws, either by being nonexistent methods or misclassifications.
