Tax Refund Estimator

A smaller refund usually means your employer withheld less tax from your paychecks throughout the year, or your income increased and pushed you into a higher bracket. Changes in tax credits, deductions, or filing status can also affect refund size. A smaller refund is not necessarily bad -- it means you kept more of your money during the year instead of giving the IRS an interest-free loan.

For 2025, the Child Tax Credit is up to $2,200 per qualifying child under age 17 (increased from $2,000 by the One, Big, Beautiful Bill Act). Up to $1,700 of this credit is refundable as the Additional Child Tax Credit, meaning you can receive it even if you owe no federal tax. The credit begins to phase out at $200,000 of modified AGI for single filers and $400,000 for married filing jointly.

Quarterly estimated tax payments are treated the same as withholding when calculating your refund. They reduce your remaining tax liability dollar-for-dollar. If your estimated payments plus any withholding exceed your total tax owed, the difference is refunded to you. If they fall short, you will owe the balance plus possible underpayment penalties.

While receiving a large refund feels rewarding, it means you overpaid your taxes throughout the year and essentially gave the government an interest-free loan. Ideally, you want to adjust your W-4 withholding so your refund is close to zero, keeping more money in your paycheck each period. You can use the IRS Tax Withholding Estimator or this calculator to fine-tune your withholding.
