CCHAxcess Tax

Every MACRS asset placed in service in the current tax year is subject to either a half-year, mid-month, or mid-quarter convention. These conventions apply only to assets with a method of "M," "ME," "MT," "MSL" or "ADS." The applicable convention is determined as follows:

Class Life of Property Convention
3, 5, 7, 10, 15, 20 or 25 Half-Year or Mid-Quarter Convention
27.5, 31.5, 39, 40 or 50 Mid-Month Convention

The half-year convention assumes property is placed in service during the mid-point of the current tax year. The mid-month convention assumes property is placed in service at the mid-point of the indicated month.

If more than forty percent of the business portion of the depreciable basis of tangible personal property (MACRS) assets are placed in service during the last 3 months of the current tax year, the mid-quarter convention is applied to MACRS personal property. A diagnostic message is issued indicating the mid-quarter convention is applied. The mid-quarter convention assumes property is placed in service during the mid-point of the computed quarter.

The cost of property acquired with a life of 27.5, 31.5, 39, 40 and 50 years is disregarded when applying the 40 percent test.

Note: MACRS personal property bought and sold in the current tax year is not included when determining if the mid-quarter convention applies. The convention computation may be overridden by making an entry in the "MACRS Convention Code" field on the Depreciation and Depletion Options and Overrides worksheet, Depreciation Options section.

Determining Applicable Convention: The choice of convention depends on the class life of the property. Here's a breakdown:

  • Class Life of 3, 5, 7, 10, 15, 20, or 25 years: Half-Year or Mid-Quarter Convention
  • Class Life of 27.5, 31.5, 39, 40, or 50 years: Mid-Month Convention

Explanation of Conventions:

  1. Half-Year Convention: Assumes property is placed in service during the mid-point of the current tax year.

  2. Mid-Month Convention: Assumes property is placed in service at the mid-point of the indicated month.

  3. Mid-Quarter Convention: Applied to MACRS personal property if more than 40% of the business portion of depreciable basis is placed in service during the last 3 months of the current tax year. This convention assumes property is placed in service during the mid-point of the computed quarter.

Exception for 40% Test: The cost of property with a life of 27.5, 31.5, 39, 40, and 50 years is disregarded when applying the 40% test.

Treatment of Bought and Sold Property: MACRS personal property bought and sold in the current tax year is not included when determining if the mid-quarter convention applies.

Override Possibility: The convention computation may be overridden by making an entry in the "MACRS Convention Code" field on the Depreciation and Depletion Options and Overrides worksheet, specifically in the Depreciation Options section.
