Method of accounting.
Method of accounting. A taxpayer that uses the PCM, EPCM, CCM, or PCCM, or elects the 10-percent method or special AMTI method (or changes to another method of accounting with the Commissioner's consent) must apply the method(s) consistently for all similarly classified long-term contracts, until the taxpayer obtains the Commissioner's consent under section 446(e) to change to another method of accounting. A taxpayer-initiated change in method of accounting will be permitted only on a cut-off basis (i.e., for contracts entered into on or after the year of change), and thus, a section 481(a) adjustment will not be permitted or required.
