MACRS Table (Method MT)
When the Tax Reform Act passed Congress in 1986, the IRS had not developed tables of calculations to assist taxpayers in determining their assets' MACRS depreciation. They issued these tables with Revenue Procedure 87-57 in mid-1987.
In general, you can use the MACRS table method to depreciate any recovery property placed in service on or after January 1, 1987, and you can adopt it for any recovery property placed in service on or after July 31, 1986. However, there is one exception: you cannot use the MACRS table method in the event of a short tax year at any time in the asset's life.
The MACRS table method generally results in the same amount of recovery as method MF, MACRS formula. Differences tend to be immaterial and are due to calculation rounding in the development of the IRS tables.
