For decades, the IRS and OMB have had an agreement that generally exempts tax rules from full OMB review. The IRS has argued that the economic effects of its actions come from the laws their rules interpret, rather than from the rules themselves, making OMB review unnecessary.

But the free-market groups said the IRS’s exemption prevents Congress from getting information about major rules that should be reported to the Government Accountability Office while curbing the White House’s ability to supervise the executive branch.

The groups also said the IRS's current practice “impacts the public’s right to learn about and comment on the economic impact of IRS rules that are subject to the Regulatory Flexibility Act.”

Groups that signed the letter include Americans for Prosperity, Americans for Tax Reform, Cause of Action Institute and Citizens Against Government Waste.

But some tax lawyers have expressed concerns that subjecting IRS rules to OMB review would slow down the process of issuing guidance needed to implement the new tax law.
