The goal is not always a giant refund. The goal is fewer bad surprises.
If you keep owing money every tax season, that does not necessarily mean you are bad with money. It often means your withholding is off.
And this year, that matters even more because the IRS updated its Tax Withholding Estimator in March 2026 to reflect changes under the current law, including deductions tied to tips, overtime, car loan interest, and seniors. The IRS says the estimator is a free tool that helps workers and retirees estimate how much federal income tax to withhold now for the taxes they’ll owe later.
That matters because withholding gets stale. A setup that worked for you last year may not fit your life now. The IRS says you should check your withholding every January and also after major life changes, including a new job, a major income change, marriage, divorce or separation, child birth or adoption, or a home purchase.
So if you changed jobs, picked up side income, got married, got divorced, retired, started getting tips, or worked more overtime, this is your sign to revisit it. The point is not always to engineer the biggest refund possible. The point is to avoid the ugly surprise that shows up when your withholding has not kept pace with your real life. That is exactly what the IRS estimator is built to help with.
And if withholding still won’t cover everything, there’s another issue to watch. The IRS says estimated tax payments are used for income that isn’t subject to withholding, and people who expect to owe tax on income without enough withholding may need to make estimated payments instead of waiting for filing season to reveal the problem.
