Thank you for responding, but this does not exactly answer my question. First, I'm not asking if the W-4 Withholding Calculator is for 2018 (of course it should be). I'm asking if it incorporates the new tax rates enacted in the Tax Cuts and Jobs Act (the new tax law, passed in December). Second, I would like to know if these new tax rates are built into the W-4 Calculator in the version of TurboTax installed on my PC, not Intuit's online tool.
