Your 2026 refund depends on what changed in your life and income, not on the year itself

The IRS does not automatically give larger refunds in 2026 than 2025. Your refund size is determined by how much tax you paid during the year through withholding or estimated payments, minus what you actually owe based on your income, deductions, and credits. If your circumstances stay the same—same job, same filing status, same dependents—your refund will likely be similar. If something changed, your refund will change with it.

The tax rates and brackets themselves do not shift year to year without an act of Congress. However, the standard deduction amount does increase slightly each year for inflation. In 2025, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. The 2026 standard deduction will be higher, but only by a few hundred dollars. That small increase alone will not dramatically change your refund unless you are right at the edge of owing tax.

Key Takeaways

  • Your refund size is based on what you paid in taxes during the year versus what you owe, not on the calendar year itself.
  • The standard deduction increases slightly each year for inflation, which may lower your taxable income slightly in 2026 compared to 2025.
  • Major changes that affect your 2026 refund include a new job, a raise, marriage or divorce, having a child, or changes to your withholding.
  • If you received a large refund in 2025, you can adjust your withholding now so you receive more money in your paychecks instead of waiting for a refund in 2026.
  • Tax law changes passed by Congress—not automatic inflation adjustments—are what create year-to-year shifts in refund amounts across many taxpayers.

What actually changes your refund from year to year

Your refund grows or shrinks based on changes in your personal situation. A promotion or new job with higher pay means more tax withheld, which can increase your refund if you do not adjust your withholding. A spouse's income, a new dependent, or a significant deduction (like mortgage interest or charitable giving) all shift the math. If you got married in 2025, your 2026 return will use married filing jointly status, which has different brackets and deductions than single status.

Changes to your withholding are the most direct lever you control. If you received a large refund in 2025, that means you had too much tax taken from your paychecks. You can file a new W-4 with your employer to claim more allowances or adjust the extra withholding amount, so less is taken out and you see more money in each paycheck instead of waiting months for a refund. The IRS withholding calculator at irs.gov can help you figure out the right number.

Life events also matter: a child born in 2025 means you can claim the child tax credit on your 2025 return (filed in early 2026) and adjust your withholding for 2026. A home purchase means mortgage interest deductions starting in 2026. A job loss or reduced hours means less income and potentially a refund even if you usually owe.

How inflation adjustments affect your 2026 taxes

Each January, the IRS adjusts tax brackets, the standard deduction, and certain credit limits for inflation. These adjustments are small—usually 2 to 4 percent—but they do reduce the amount of income that is taxed. For 2026, the standard deduction will increase by roughly 3 to 4 percent from the 2025 amount, though the exact figure is not announced until late October 2025.

A higher standard deduction means more of your income is untaxed, which can lower your tax bill. If your income stays flat but the standard deduction rises, you may owe less tax and receive a larger refund—or owe nothing at all if you were close to breaking even. However, this effect is modest. A $400 increase in the standard deduction might save you $80 to $100 in tax, depending on your tax bracket.

These adjustments are not new money or a surprise refund. They are built into the tax code automatically and affect everyone. They do not require you to do anything; the IRS uses the new numbers when processing your return.

Tax law changes that could affect 2026 refunds

Congress occasionally passes tax law changes that shift refund amounts. For example, the child tax credit, the earned income tax credit, and various deductions have been expanded or reduced by legislation in the past. If Congress changes the tax code before 2026, those changes will affect what you owe and what you get back.

As of now, there is no confirmed major tax law change scheduled for 2026. However, tax law can change at any time through new legislation. If you want to know whether a specific credit or deduction is changing, check the IRS website (irs.gov) or speak with a tax professional closer to tax season. Do not assume your 2026 refund will be larger or smaller based on speculation about future law changes.

How to estimate your 2026 refund now

You can make a rough estimate of your 2026 refund by looking at your 2025 tax return and considering what will change. Start with your 2025 income and add or subtract any expected changes: a raise, a new job, a spouse's income, a new dependent, or a major deduction. Then estimate your tax using the 2026 tax brackets and standard deduction (which you can find on the IRS website once they are published in October 2025).

Subtract the total tax you expect to owe from the total tax you expect to have withheld during 2026. If withholding is higher, you will get a refund. If withholding is lower, you will owe. This is a rough calculation; a tax professional or tax software can give you a more precise number.

The IRS withholding calculator is the most accurate tool for this. You enter your income, filing status, dependents, and other details, and it tells you how much should be withheld from each paycheck to hit your target—whether that is a small refund, no refund, or a small amount owed. You can run this calculation now and adjust your W-4 before 2026 begins.

Adjusting your withholding to avoid a large refund

If you received a large refund in 2025, you do not have to accept the same outcome in 2026. A large refund means the IRS held your money interest-free for a year. By adjusting your withholding, you can get that money in your paychecks instead, where you can use it or invest it yourself.

To adjust withholding, complete a new W-4 form and submit it to your employer's payroll department. You can claim more allowances (which reduces withholding) or reduce the extra withholding amount you specified. The form is free and takes a few minutes. Your employer must honor it within a reasonable time, usually one to two pay periods.

If you have multiple jobs or a spouse who works, withholding becomes more complex. The IRS withholding calculator accounts for this and can tell you the right W-4 entries for each job. If you are self-employed, you make quarterly estimated tax payments instead of having withholding, so you control the amount directly.

Frequently Asked Questions

Will the IRS give me a bigger refund in 2026 just because it is a new year?

No. The IRS does not automatically increase refunds year to year. Your refund is based on what you paid in taxes versus what you owe, which depends on your income, deductions, and credits. The only automatic change is a small increase in the standard deduction for inflation, which may lower your tax bill slightly but will not create a windfall.

What if I got a large refund in 2025—will I get one in 2026 too?

Only if your situation stays the same and you do not adjust your withholding. If you want a smaller refund in 2026, file a new W-4 with your employer to reduce the amount of tax withheld from your paychecks. Use the IRS withholding calculator to find the right number.

Does a raise mean my 2026 refund will be bigger?

Not automatically. A raise increases your income, which increases the tax owed. If your employer does not adjust your withholding, more tax will be taken out, which could increase your refund. However, if you want to avoid a larger refund, you can adjust your W-4 to account for the raise.

When will I know the 2026 standard deduction amount?

The IRS announces the 2026 standard deduction and tax brackets in late October 2025. You can find this information on irs.gov. The increase is usually 2 to 4 percent from the prior year, but the exact amount depends on inflation data released earlier that year.

Can Congress change the tax code before 2026 and affect my refund?

Yes, Congress can pass new tax laws at any time. However, there is no confirmed major tax change scheduled for 2026 as of now. If a significant change occurs, the IRS will publish guidance and update tax forms. Check irs.gov or speak with a tax professional if you are concerned about a specific credit or deduction.
