BIR REVENUE MEMORANDUM ORDER NO. 34-92, September 04, 1992
LIFTING THE SUSPENSION OF AUDIT OF INCOME AND BUSINESS TAX RETURNS FOR 1990 AND 1991
The audit should not be confined to the examination of the taxpayer’s books of accounts and other records. Relevant information from sources external to the taxpayer’s own accounting and other records should be gathered by accessing the records of persons with whom the taxpayer has transactions or other entities, such as the CB, BOC, etc., which may have data on the gross sales, receipts or income generated by the taxpayer.
Deficiency tax determinations should be based not only on mere disallowance of deductions but on findings of underdeclarations which are undeniably prevalent. The performance of the individual revenue officers will be evaluated through post-selective, post-audit review of reports submitted by them.
This Revenue Memorandum Order shall take effect immediately.
Adopted: 4 Sept. 1992
Commissioner of Internal Revenue
