Congress Should Put Tax Extenders to Rest

5 min readBy: Robert Bellafiore

House Ways and Means CommitteeThe Committee on Ways and Means, more commonly referred to as the House Ways and Means Committee, is one of 29 U.S. House of Representative committees and is the chief tax-writing committee in the U.S. The House Ways and Means Committee has jurisdiction over all bills relating to taxes and other revenue generation, as well as spending programs like Social Security, Medicare, and unemployment insurance, among others. Chairman Kevin Brady (R-TX) announced in September that “taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. extenders,” a set of tax provisions that have been temporarily continued for more than a decade, will receive attention after the midterm elections. Now that the lame duck session of Congress begins, Congress must answer the question: which extenders should be extended and which should expire?

Fortunately, my colleague Erica York has identified exactly which extenders fall into those categories. Congress should follow Erica’s guide and identify which extenders are no longer needed because of the Tax Cuts and Jobs Act (TCJA), which extenders are poor policy and should be allowed to expire, and which should be left up to Congress’ discretion.

Some extenders are now redundant, following the TCJA. The TCJA allows for full expensingFull expensing allows businesses to immediately deduct the full cost of certain investments in new or improved technology, equipment, or buildings. It alleviates a bias in the tax code and incentivizes companies to invest more, which, in the long run, raises worker productivity, boosts wages, and creates more jobs. of capital investments for five years, phased out over time, for qualified property. Six extenders provide similar treatment to different types of property, and an additional provision overlaps with the TCJA’s treatment of Section 179 expensing. Given their redundancy, such extenders are no longer needed.

Some extenders should simply be allowed be expire. Seventeen extenders favor specific industries, making the tax code less neutral. Narrow benefits for certain economic groups are never good policy, and Congress should remove those provisions that unfairly favor some businesses over others.

Finally, two extenders could be reasonable policies, depending on congressional priorities. These extenders, for railroad track maintenance and mine rescue team training, should be left to congressional discretion. However, it would be better for them to be made permanent, rather than left as temporary provisions.

As lawmakers consider ways to build on tax reform, they should subject extenders to a “rigorous test,” as Rep. Brady said earlier this year. Instead of performing the ritual of prolonging temporary provisions, Congress should decide which provisions, if any, are good policy and deserve to be made permanent, and which should be allowed to expire once and for all.
