The Income Tax Compliance Cost of Big Business

income taxes is approximately $1.565 million, implying an aggregate annual compliance cost of over $2 billion. As a fraction of revenue raised, these compliance costs are lower than estimates that have been made for the individual income tax. The cost-to-revenue ratio is higher for state corporate tax systems than it is for the federal tax system, presumably reflecting the nonuniformity of state tax systems There is near unanimity among senior corporate tax officers that the Tax Reform Act of 1986 added complexity to the tax system, resulting in a combination of higher compliance costs and less accurate information transmission. They point to, in particular, the alternative minimum tax, inventory capitalization rules, and the taxation of foreign-source income as growing sources of complexity.
