Taxpayers get more time to fight IRS tax disputes in court.

What it does

This bill gives taxpayers more time to challenge IRS tax bills. It stops the clock on refund deadlines while a taxpayer fights the IRS. The IRS cannot automatically use overpayments to pay disputed taxes during the fight. Tax Court can now review whether the tax bill was correct. Tax Court can also review how the IRS collected the money.

Who it affects

Taxpayers who dispute their tax bills gain more time and more power in court. They can now challenge the tax bill itself in Tax Court.

One thing to notice

Tax Court can now review the underlying tax bill itself. Before, Tax Court could only review the IRS's collection method.
