Your refund size depends on what you earned, what you paid in taxes, and what deductions or credits you can claim — not on the year itself
The year changing from 2024 to 2025 does not automatically make your refund bigger or smaller. What matters is your actual income, the taxes withheld from your paychecks, and the deductions or credits you may have access to for on your 2025 tax return. That said, a few real changes in 2025 do affect how much you might owe or get back.
The main change is that tax brackets and standard deduction amounts shift each year to account for inflation. For the 2025 tax year (the return you file in early 2026), the standard deduction increased compared to 2024. If you take the standard deduction rather than itemizing, this larger deduction means less of your income is taxable, which could lower the taxes you owe — and potentially increase your refund if your employer withheld the same amount as before.
Beyond that, your refund depends entirely on your personal situation: whether you got a raise, changed jobs, got married, had a child, or changed how much you asked your employer to withhold from each paycheck. Those are the levers that actually move your refund up or down.
Key Takeaways
- The standard deduction for 2025 is higher than 2024, which reduces taxable income for most people and may increase refunds if withholding stays the same.
- Your refund size is determined by comparing total taxes paid (through withholding and estimated payments) against total taxes owed based on your income and deductions.
- Changes in your life — new job, marriage, child, side income — affect your refund far more than the calendar year does.
- If you received a large refund in 2024, you can adjust your withholding for 2025 to get more money in each paycheck instead of waiting for a refund.
How the standard deduction increase affects your refund
The standard deduction is a fixed dollar amount you can subtract from your income before calculating taxes owed. For 2025, this amount increased from 2024 — the exact increase varies depending on your filing status (single, married filing jointly, head of household, and so on). You can find the 2025 standard deduction amounts on the IRS website or on the tax forms you receive.
If you take the standard deduction and your employer withheld the same amount from your paychecks in 2025 as in 2024, you would owe less in taxes because more of your income is now deduction-protected. That difference could show up as a larger refund. However, this only helps if your income and withholding stayed the same — if you got a raise or changed jobs, the effect may be offset.
Life changes that actually shift your refund
A new job, a raise, a second income, marriage, divorce, or a new child all change what you owe in taxes. Each of these changes your total income, your tax bracket, or the credits you can claim — and any of those can make your refund larger or smaller than last year.
If you started a new job in 2025, your new employer may have withheld taxes differently than your old one did, even if the pay is the same. If you got married, you may now file jointly instead of single, which changes your tax brackets and standard deduction. If you had a child, you may now claim the child tax credit, which can significantly increase your refund. These personal changes matter far more than the year-to-year shift in tax brackets.
Checking whether your withholding is still correct
Your refund is essentially the difference between what you paid in taxes and what you actually owed. If your employer withheld too much, you get a refund. If they withheld too little, you owe. The IRS provides a withholding calculator on its website that lets you estimate whether your current withholding is on track.
If you received a large refund in 2024, that means your employer withheld more than necessary — you gave the government an interest-free loan all year. For 2025, you can adjust your withholding by submitting a new W-4 form to your employer. Lowering your withholding puts more money in your regular paychecks instead of waiting until tax time. This does not change your total refund; it just spreads the money differently.
Tax credits that may have changed
Some tax credits — money the government gives you to reduce your tax bill — change from year to year or depend on your income. The child tax credit, the earned income tax credit, and education credits are common examples. If your income changed in 2025, you may no longer may have access to for a credit you claimed in 2024, or you may now may have access to for one you did not before.
Credits are worth checking because they directly reduce your tax bill dollar-for-dollar. A new credit can turn a small refund into a large one. Losing a credit can do the opposite. If you had a major life change in 2025 — a child, a significant income drop, or starting college — review which credits might explore to you.
Why comparing 2024 and 2025 refunds can be misleading
People often expect their refund to be similar year to year, but that expectation usually does not hold. Your 2024 refund reflected your 2024 income, withholding, and life situation. Your 2025 refund reflects 2025 — and if anything changed, the refund will too. A smaller refund does not mean something went wrong; it may just mean your circumstances shifted.
The only way to predict your 2025 refund is to look at your actual 2025 numbers: your total income, what was withheld, and what deductions or credits you can claim. Generic statements about "bigger refunds in 2025" do not account for your specific situation.
Frequently Asked Questions
Did the IRS change the tax rates for 2025?
Tax rates themselves did not change, but the income ranges for each rate (called tax brackets) shifted upward to account for inflation. This means you may pay the same percentage of tax on slightly more income before moving to the next bracket. The IRS publishes updated brackets each year.
If I got a big refund last year, will I get one again in 2025?
Not necessarily. A large refund in 2024 means you overpaid taxes that year. Unless your 2025 income, withholding, and deductions are identical to 2024, your refund will be different. If your situation stayed the same, you can adjust your W-4 to reduce withholding and get more money in each paycheck instead.
Does having a side job or freelance income change my refund?
Yes. Side income increases your total taxable income, which usually means you owe more in taxes. If you did not have this income in 2024, your 2025 refund will likely be smaller unless you also increased your withholding or made estimated tax payments throughout the year.
When should I use the IRS withholding calculator?
Use it after any major life change — new job, marriage, child, significant income shift — or if you received a refund or owed taxes last year and want to adjust for 2025. The calculator takes a few minutes and helps you decide whether to change your W-4.
