The IRS has increased user fees for many of its services to make up for reduced appropriations from Congress. Some key fee increases include raising the cost of a prefiling agreement request from $50,000 to $218,600 and more than doubling the cost of a traditional letter ruling from $14,000 to $28,300. The IRS is able to set and spend user fee revenue with little oversight from Congress. Critics argue the IRS lacks transparency in how it calculates and sets user fees and is using the fees to fund areas where Congress has reduced appropriations rather than taxpayer services as directed.
