The Tax Cuts and Jobs Act marked the first overhaul of the tax code in more than three decades.
Massive changes that went through include a doubling of the standard deduction, the elimination of personal exemptions and a cut to individual income tax rates.
In 2018, the first year of the overhaul, the IRS issued 111.6 million refunds for 2018 returns filed through Nov. 22, with taxpayers getting an average refund of $2,860.
