Causes and Effects of the Tax Return Blockade
A survey of the work done and remaining to be done in the Bureau of Internal Revenue on back income tax returns discloses an accumulation of 1,605,955 returns, or 22 per cent of the whole number received by the Income Tax Unit for audit since 1917. These figures are as of March 1, 1924, the last date for which any statistics are available. They do not include returns filed March 15, upon which the work of audit has not yet started. Of the back returns still awaiting final audit 28,203 are 1917 and 1918 returns. The evidence is that the Income Tax Unit has only recently begun to make substantial progress on the auditing of back returns.
