Many taxpayers discover at filing time that their tax payments didn’t match their actual liability. Overwithholding reduces cash flow, while underwithholding can lead to large balances due, interest, and penalties. If you received a big refund or owed a lot when filing your 2025 return, now is the time to review your withholding for 2026.
Review Your Income and Withholding
If most of your income comes from wages, your employer withholds taxes based on IRS tables. These are estimates, and your personal situation may differ. Larger deductions or credits can make withholding too high, while additional income from other sources can make it too low.
Adjust Your Withholding If Needed
Estimate your tax liability for the year and, if necessary, adjust your withholding by submitting a new Form W‑4. The IRS Tax Withholding Estimator reflects changes from the One Big Beautiful Bill Act (OBBBA), including tax breaks for tips, overtime, seniors, auto loan interest, families, homeownership, and charitable giving. Once submitted, changes usually take a few weeks to apply.
Revisit Withholding After Life Changes
Major life events can affect your withholding accuracy. Consider adjustments if you:
- Experience a significant income change
- Get married or divorced
- Have a child or add a dependent
- Buy a home
- Receive new income not subject to withholding
Use Withholding Strategically
If part of your income isn’t subject to withholding, estimated tax payments may be required. Increasing withholding can help avoid penalties, since withholding is treated as paid evenly throughout the year. You can adjust withholding from wages, a spouse’s income, or even retirement distributions.
Find the Right Balance
Aligning your withholding with your expected tax liability helps you maintain better cash flow and avoid surprises at filing time. Reviewing your current withholding and estimated payments now can ensure smoother finances in 2026.
