Get your taxes done using TurboTax

It is a good idea to double-check paystubs throughout the year for proper withholding as our income can change.  While adding up the federal or state withholding and comparing to last year's tax return is a good practice, if you have any life changes these can directly impact income tax liability and mean that the W4 needs to be updated.  Some things that can qualify a new W4 that are often missed is:

  1.  Change of Address
  2.  Change in Marital Status
  3. Change of Name
  4. Change in Income
  5. Caring for a Dependent
  6. Caring for a Parent

If any of the above change, I recommend starting the W-4 calculator and then monitoring the paystubs for the change.  The important take away is that the W-4 is not a static document and needs to be revisited at least twice a year, in my opinion.
