The Pay-As-You-Go (PAYGO) rule, which was in place in the 110th and 111th Congresses and reinstated in the 116th Congress, requires mandatory spending increases to be offset with either an equal decrease in mandatory spending or increase in revenue. PAYGO requires provisions be compliant in the current year, the budget year, and over the 5- and 10-year budget windows. During the 117th Congress, measures to address the COVID-19 pandemic and measures to address climate change are exempt from PAYGO.
