“They say, 'I'll do zero so I don't get in trouble.' What most people should know is that each [W-4 allowance] shelters an amount equal to the personal exemption amount.”
“If you know you're going to put $3,000 into an IRA, or money into a dependent care account or flexible spending account, add that up. Every time you reach that exemption amount, add another allowance on your W-4.”
