The new rates went into effect January 1. It was estimated that we wouldn't see the effects of the cuts until February because it would take that long for the IRS to update their witholding charts. I believe companies are free to do the math themselves and adjust witholding accordingly but most will wait on the IRS. QuickBooks payroll users got the updates this month. My part-time paycheck ($14,000) shows a $20 per month increase in take-home.

To clarify, $14,000 per year.
