The Internal Revenue Service needs to pick up the pace on finalizing its IT modernization plans. Of the nearly $80 billion in Inflation Reduction Act funds appropriated to the tax agency as a whole, $4.8 billion has been set aside for business systems modernization. Another $25.3 billion is ticketed for operations support. The IRS spent $3.3 billion on IT investments in fiscal year 2022 and $4.4 billion the following year.
