How to know if you'll owe or get money back
Whether you get a refund in 2026 depends on how much tax was withheld from your paychecks during the year versus how much you actually owe. If your employer withheld more than you owe, you get a refund. If you withheld less, you owe money. If they match exactly, you break even.
The only way to know before you file is to look at your W-4 form — the document you filled out when you started your job that tells your employer how much to withhold. If you haven't changed it since 2024, your withholding will likely stay the same in 2026. If your life changed (marriage, second job, dependents, major income shift), your withholding may be off.
You can run a rough estimate using the IRS Withholding Calculator on irs.gov, which asks about your income, filing status, and deductions. It will tell you whether you're likely to owe or get a refund, and by roughly how much. This takes about 10 minutes and requires your most recent pay stub and last year's tax return.
Key Takeaways
- Your refund or bill in 2026 depends on what your employer withheld in 2026, not on what happened in previous years.
- The IRS Withholding Calculator on irs.gov can estimate whether you'll owe or get money back before you file.
- If you got a large refund last year, you can adjust your W-4 now to reduce withholding and get more money in each paycheck instead.
- Life changes like marriage, a second job, or new dependents can shift you from a refund to owing money, or vice versa.
- You won't know your exact refund or bill until you file your return in early 2027, after the tax year ends.
Why your 2025 refund doesn't predict your 2026 refund
Many people assume that if they got a refund in 2025, they'll get one in 2026. That's not how it works. Each year stands alone. Your 2026 refund depends only on what was withheld from your 2026 paychecks and what you actually owe on your 2026 income.
If you got a large refund in 2025, that means your employer withheld too much that year. You can change that for 2026 by updating your W-4 form now. You can submit a new W-4 to your employer's payroll department at any time — you don't have to wait for a specific date. This will reduce the amount withheld from each paycheck going forward, which means less refund (or possibly owing money) when you file in 2027.
The opposite is also true: if you owed money in 2025, you can increase your withholding for 2026 by adjusting your W-4 again. This gives you a better chance of breaking even or getting a small refund instead of a bill.
Changes that affect your 2026 refund
Several life events can shift whether you get a refund or owe money. Getting married, having a child, taking a second job, or a major raise all change your tax picture. So does losing a job, retiring, or having significant investment income.
If any of these happened to you between now and the end of 2026, your withholding may no longer match your actual tax bill. The sooner you update your W-4, the sooner your paychecks adjust. If you wait until you file in early 2027, you'll either get a large refund or face a bill you weren't expecting.
You can also claim more or fewer dependents on your W-4, which changes your withholding. If you're supporting a child or elderly parent for the first time, claiming them can reduce your withholding. If you're no longer supporting someone, increasing your withholding can prevent a surprise bill.
Using the IRS Withholding Calculator
The IRS Withholding Calculator is free and available on irs.gov under "Tools". It asks for your filing status, income from all jobs, expected deductions, and any tax credits you plan to claim. It then estimates your total tax bill and compares it to what's been withheld so far.
You'll need your most recent pay stub (to see year-to-date withholding) and last year's tax return (to see your deductions and credits). The calculator takes about 10 minutes and produces a recommendation for how many allowances to claim on your W-4 to get closer to zero refund or bill.
This is an estimate, not a may provide. Your actual refund depends on your final 2026 income, which may change if you get a raise, lose hours, or have unexpected income. But it gives you a solid starting point and is far more accurate than guessing.
When you'll know your actual refund amount
You won't know your exact refund or bill until you file your 2026 tax return, which you'll do in early 2027 (usually between January and April). The IRS doesn't calculate your refund — you do, by reporting your actual income and deductions on your return.
Once you file, the IRS processes your return and either sends your refund or bills you. If you file electronically and choose direct deposit, refunds typically arrive within 21 days. If you file by mail or request a check, it takes longer — usually four to six weeks.
You can track your refund status using the IRS "Where's My Refund?" tool on irs.gov, which updates every 24 hours after you file. It will tell you the exact amount and the expected deposit date.
What to do if you think you'll owe money
If the Withholding Calculator suggests you'll owe money in 2026, you have options. The simplest is to increase your withholding now by adjusting your W-4. This spreads the tax bill across your paychecks instead of facing a lump sum in 2027.
If you can't increase withholding (because you're self-employed or have irregular income), you can set money aside each month to cover the expected bill. Some people open a separate savings account and transfer a fixed amount from each paycheck.
You can also make estimated tax payments to the IRS throughout 2026 if you expect to owe more than $1,000. These are quarterly payments (due April 15, June 15, September 15, and January 15) that reduce your bill when you file. The IRS website has a form and instructions for estimated payments.
Refunds if you have multiple jobs or self-employment income
If you work two jobs or are self-employed, withholding gets more complicated. Your primary job's W-4 is based on that income alone, so if you have a second job, your total withholding may be too low. The IRS Withholding Calculator accounts for this — just enter all your income sources.
One common fix is to claim zero allowances on your second job's W-4, which maximizes withholding from that paycheck. This often brings your total withholding closer to what you'll actually owe. Self-employed people typically can't use W-4 withholding at all and instead make quarterly estimated payments.
If you're self-employed and expect to owe more than $1,000 in 2026, you should make estimated tax payments. The IRS Form 1040-ES walks you through calculating them, and you can pay online, by mail, or by phone.
Frequently Asked Questions
Can I change my W-4 in the middle of 2026?
Yes. You can submit a new W-4 to your employer's payroll department at any time, and the change takes effect on your next paycheck. If you realize mid-year that you're on track for a large bill or refund, adjusting then can help.
What if I have no income in 2026 — do I still get a refund?
No. A refund only happens if you filed a return and had tax withheld. If you had no income and no withholding, there's nothing to refund. If you had withholding but no income (for example, you worked part of the year), you may get a refund when you file.
Does getting a refund mean I'm doing something wrong?
No. A refund just means your employer withheld more than you owed. Some people prefer this because it forces them to save. Others prefer to adjust their W-4 to get more money in each paycheck and manage their own savings.
How much will my refund be if I file in 2027?
You won't know until you file. The Withholding Calculator can estimate it based on your current income and withholding, but your actual refund depends on your final 2026 income, deductions, and any tax credits you claim.
What if I'm retired — will I get a refund in 2026?
Only if you had income and tax withheld in 2026. Social Security benefits may be partially taxable, and if tax was withheld from your benefits, you could get a refund. Pension and investment income work the same way — withholding determines whether you get a refund or owe.
