The IRS is telling workers across the country to review their paycheck withholding now, warning that ignoring it could leave them owing more when they file. According to the IRS, a quick tax withholding check today can prevent an unwelcome bill next spring – or a refund that’s smaller than expected.
The reminder, reported by The Sun, comes as some taxpayers face a September 15 deadline for estimated payments. Getting the numbers right now gives you time to fix any shortfall before the year closes.
Why is the IRS pushing a tax withholding check now?
Withholding is the amount your employer takes out of each paycheck and sends to the IRS on your behalf. If too little comes out during the year, you can end up owing a lump sum at filing time. If too much comes out, you hand the government an interest-free loan and wait for a refund.
The IRS says the goal is balance. Because pay, side income, and household circumstances change through the year, the amount withheld in January may no longer match what you actually owe by September. That gap is exactly what a mid-year review is meant to catch.
How do I check my tax withholding?
The IRS points taxpayers to its free online Tax Withholding Estimator, which walks you through your income, deductions, and current withholding to show whether you’re on track. To use it effectively, have these ready:
- Your most recent pay stubs: for yourself and your spouse if you file jointly.
- Other income details: such as self-employment, investment, or gig work earnings.
- Your most recent tax return: to help estimate deductions and credits.
If the estimator shows you’re falling short, you can submit an updated Form W-4 to your employer to increase what’s withheld from future paychecks. For example, if the tool shows you’ll be $600 under by year-end, spreading extra withholding across your remaining pay periods closes that gap before you ever file.
Who especially needs to review their withholding?
Because withholding depends on individual circumstances, some people are far more likely to be off track than others. The situations that most often cause a mismatch include:
- People with a second job or side income: earnings that don’t have tax withheld at the source.
- Anyone with a major life change: marriage, divorce, a new child, or a home purchase.
- Self-employed and gig workers: who typically owe through estimated payments rather than paycheck withholding.
- Those who owed or got a large refund last year: a sign the current setup may be off.
What is the September 15 deadline?
The September 15 date mentioned in the reporting relates to quarterly estimated tax payments. These payments matter most for people whose income isn’t covered by regular paycheck withholding – freelancers, contractors, and those with significant investment or self-employment earnings.
If you fall into that group and haven’t paid enough during the year, missing an estimated payment deadline can trigger an underpayment penalty on top of the tax itself. That’s why the IRS frames acting now as a way to avoid extra costs, not just extra paperwork.
What happens if I don’t adjust my withholding?
Nothing forces you to change anything – but the consequences show up at filing time. If your withholding falls short across the year, you could owe a larger balance than you planned for, and in some cases face a penalty for underpaying.
On the other side, over-withholding isn’t free either. Money held back unnecessarily is cash you can’t use during the year. The IRS’s point is that checking now puts you in control of the outcome instead of being surprised by it.
Where can I find the official IRS tools?
The IRS hosts its Tax Withholding Estimator and the latest Form W-4 on its official website, IRS.gov. The guidance highlighted by The Sun echoes the agency’s standard year-round advice: review early, adjust if needed, and don’t wait until you’re filing to discover a problem.
A few minutes with the estimator now can mean the difference between a manageable tax season and an unexpected bill. If your numbers look off, updating your W-4 with your employer is the fastest way to correct course before the year ends.
