There is a brand new W-4 form for 2020, which makes a number of changes. Most significant is that there is no longer the concept of “allowances”. Instead, one essentially directly lists other income and deductions in annual dollar amounts. Calculations based on W-4s filled out in 2019 and earlier will remain in place, but early January may be good time to re-evaluate your withholding needs for 2020, and submit a new form if necessary.
Get all the info on our newly revised W-4 page, and be sure to check out our Withholding Calculator, which will allow you to determine, in advance, what amounts will be withheld from your paychecks based on your taxable salary if you fill out the 2020 W-4 in the most straightforward manner.
