Why a big refund is not good news
A refund is your own money returned without interest, twelve months late.
A refund is an overpayment
If you receive several thousand dollars back, you overpaid by a few hundred every month during the year.
Adjusting withholding is straightforward
A revised W-4 changes your take-home pay within a pay cycle or two. The IRS withholding estimator gives you the figure to enter.
Keep a buffer
Aim to land slightly over rather than slightly under, since underpayment can carry a penalty.
Self-employed people face the reverse problem
No withholding means quarterly estimates. Missing them creates penalties even when the annual return is correct.
