Understanding Tax Withholding
Tax withholding is the amount your employer takes from each paycheck and sends to the IRS on your behalf. Getting it right means you won't owe a large tax bill or give the IRS an interest-free loan.
The Goldilocks Principle
Too Little Withholding:
- Owe taxes at filing time
- Possible underpayment penalties
- Risk of owing $1,000+
Too Much Withholding:
- Large refund (average: $3,000)
- Gave government an interest-free loan all year
- Less money in your paycheck throughout the year
Just Right:
- Owe little or get small refund
- Maximize take-home pay
- No penalties, no waiting for refund
When to Update Your W-4
Update your withholding when:
- You get married or divorced
- You have a child
- You buy a home
- You start/stop working (spouse)
- You get a significant raise
- Tax laws change (like 2026 updates!)
