MACRS - Half-year convention

Per Pub 946, MACRS assets are subject to the half-year (HY) convention if the mid-quarter and mid-month conventions don't apply. All property placed in service or disposed of during the tax year is then treated as placed in service or disposed of at the midpoint of the tax year, meaning a half-year of depreciation is allowed.

If using this convention, enter HY
under column (e) in Part III of Form 4562.
