The Tax Cuts and Jobs Act made major changes to the tax law. Because of this, you should do a paycheck checkup using the Withholding Calculator on IRS.gov.

Recent changes affecting withholding include:

Reduced tax rates

Elimination of personal exemptions

Increased standard deductions: $12,000 for singles, $18,000 for heads of households and $24,000 for married couples filing jointly

Increased child tax credit: $2,000 per qualifying child and a new $500 credit for other qualifying dependents

Changes to itemized deductions
