Recently Expired Individual Tax Provisions ('Tax Extenders'): In Brief [March 30, 2018] [open pdf - 637KB]
"In the past, Congress has regularly acted to extend expired or expiring temporary tax provisions. Collectively, these temporary tax provisions are often referred to as 'tax extenders.' Of the 33 temporary tax provisions that had expired at the end of 2016 and extended retroactively through 2017, three are individual income tax provisions. The three individual provisions that expired at the end of 2017 have been included in recent tax extenders packages. The above-the-line deduction for certain higher-education expenses, including qualified tuition and related expenses, was first added as a temporary provision in the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16), but has regularly been extended since. The other two individual extender provisions are housing related. The provision allowing homeowners to deduct mortgage insurance premiums was first enacted in 2006 (effective for 2007). The provision allowing qualified canceled mortgage debt income associated with a primary residence to be excluded from income was first enacted in 2007. Both provisions were temporary when first enacted, but in recent years have been extended as part of the tax extenders."
