With tax season here, taxpayers and certified public accountants will be calculating taxes under the new tax law for the first time.
The big question for taxpayers is “How will the new law impact my tax bill?”
A significant concern among investors is the limit or repeal of many popular tax deductions. At the same time, tax rates are lower, the standard deduction has nearly doubled, and most taxpayers will not be subject to the alternative minimum tax (AMT).
The following case examples compare tax bills under the new tax law for certain taxpayers.
Taxpayer owes slightly more under the new law
Taxable income in 2018 is higher than 2017 due to the loss of the personal exemption and limits on certain deductions ($10,000 limit on deducting state and local taxes (SALT), repeal of miscellaneous deductions) while tax rates are lower (taxpayer in a 28% marginal tax bracket for 2017, a 24% marginal tax bracket in 2018).
Taxpayers owe significantly less under the new law
Even though personal exemptions and deductions are scaled back, these taxpayers benefit from lower tax rates, no AMT, and the expanded child tax credit (CTC).

Taxpayers owe more under the new law
