Withholding Tips

Avoid Surprises

Check your withholding mid-year, especially after life changes (marriage, new job, baby). Adjust W-4 to avoid a big bill or giving the IRS an interest-free loan.

Refund vs Paycheck

A big refund means you over-withheld. That money could have been in your paycheck earning interest. Aim for a small refund or break-even.

Safe Harbor

To avoid penalties, withhold at least 90% of this year's tax or 100% of last year's tax (110% if income over $150K). This is called "safe harbor."

Refund vs Bigger Paycheck
