CPA REG: MACRS Property Class and Convention Selection

MACRS questions are usually won before the first table percentage is applied. The hard part is not memorizing every percentage. The hard part is choosing the right lane: depreciable or nondepreciable, real property or personal property, recovery period, convention, and then the year of service or disposition.

For CPA REG and TCP candidates, the safest workflow is to treat MACRS as a sequence of classification decisions. Do not jump straight from purchase price to a table.

Start With Depreciable Basis

Depreciation applies to the cost or other basis of property that is used in a business or income-producing activity and wears out, decays, gets used up, becomes obsolete, or loses value from use. Land is the classic exam exception. Land may be acquired with a building, but land itself is not depreciated.

Worked Example: Building And Land

Assume Harbor Loft LLC buys a small rental property for 840,000. The appraisal allocates 210,000 to land and 630,000 to the building. The MACRS starting point is not 840,000. The 210,000 land allocation is excluded from depreciation, while the building basis is tested under the real-property rules.

The exam trap is treating the whole purchase price as depreciable just because the taxpayer bought one property. Separate the asset components before choosing a table.

Real Property Uses Mid-Month Convention

Residential rental property and nonresidential real property use real-property recovery periods and the mid-month convention under MACRS. The convention treats the property as placed in service, or disposed of, at the midpoint of the month. That is why the month matters for real property, even when the day is early or late in the month.

Residential Rental Versus Nonresidential Real Property

At a high level:

• Residential rental property is recovered over 27.5 years.
• Nonresidential real property is recovered over 39 years.
• Land is not recovered through depreciation.
• The mid-month convention is used for real property.

Worked Example: Rental Placed In Service

Riverbend Flats places a residential rental building in service in April. The building's depreciable basis is 510,000 after removing land. A CPA exam problem may give a MACRS table rate for residential rental property placed in service in April. Use the real-property table and mid-month convention lane. Do not use a half-year personal-property table merely because the property was placed in service during the year.

Personal Property Usually Starts With Half-Year Convention

Tangible personal property such as equipment, computers, office machinery, and furniture is not automatically real property merely because it sits inside a building. For personal property, the usual MACRS convention is half-year convention unless the mid-quarter convention is triggered.

Half-year convention generally treats property as placed in service or disposed of at the midpoint of the tax year. In a first-year personal-property question, that means the table already builds in the half-year assumption. Candidates should not add an extra six-month proration on top of a half-year table percentage unless the problem specifically requires a different computation.

The Mid-Quarter Test Is A Personal-Property Timing Test

The mid-quarter convention can replace half-year convention when a large share of the year's depreciable personal property is placed in service during the last three months of the tax year. The exam version usually asks whether more than the allowed fourth-quarter threshold has been crossed.

Worked Example: Fourth-Quarter Concentration

Juniper Dental Group places the following depreciable personal property in service:

• March equipment: 80,000
• July office furniture: 40,000
• November imaging equipment: 100,000

Total personal property placed in service is 220,000. Fourth-quarter personal property is 100,000, or about 45.5% of the total. Because the fourth-quarter share exceeds 40%, Juniper should not use the default half-year convention for that year's personal-property additions. The mid-quarter convention lane is triggered.

If the November equipment had been only 70,000, the fourth-quarter share would be 70,000 / 190,000, or about 36.8%. In that revised fact pattern, the mid-quarter convention would not be triggered, so the personal-property additions would stay in the half-year lane.

Property Class Still Matters After Convention

Recovery period and convention are separate choices. A computer might be five-year property, while office furniture is commonly seven-year property. The convention tells you how the first and last years are treated. The recovery period tells you which table family and recovery life apply.

Exam-Friendly Order

Use this order before touching the table:

1. Separate land and other nondepreciable basis.
2. Decide whether the asset is real property or personal property.
3. Assign the recovery period.
4. Select the convention.
5. Apply the correct service-year table percentage.
6. Check whether the fact pattern asks about disposition-year depreciation.

Form 4562 Is The Reporting Anchor

Form 4562 is the federal form used for depreciation and amortization, including MACRS depreciation and certain property-related deductions or elections. For exam purposes, Form 4562 is the reporting location, but it does not rescue a bad classification. The preparer still needs the correct asset description, basis, placed-in-service date, recovery period, method, and convention.

Exam Framing

CPA questions often hide the answer in the convention, not in the arithmetic. Watch for these traps:

• Using personal-property half-year convention for a building.
• Depreciating land because it was purchased with a building.
• Applying mid-quarter convention to real property.
• Forgetting that the mid-quarter test looks at the timing of personal-property additions.
• Adding manual proration when the table percentage already reflects the convention.
• Treating a disposition month like a full year of depreciation.

The clean exam habit is to write the lane first: real property - mid-month, personal property - half-year, or personal property - mid-quarter. Then compute.
