Withholdings

I know you've most likely already answered several questions like this, so thank you and god bless ya for your patience in this forum, lol.

 

My wife and I both work, ages 56 and 58, she makes $90K and I make between $80-$110K (range includes quarterly bonuses) annually.  We both have claim 0 on our W-4s and end up owing a bit each tax year.  to eliminate owing anything, is it as simple as taking the amount owed from previous year (obviously things can change) and make that an extra cash amount withholding spread through the year?

 

Many thanks!
