Why do I get a smaller tax refund if I earned the same? Understand your W-2

The refund starts long before filing

When your employer withholds federal income tax, they advance part of that tax during the year. The amount depends on what you earn and the information you provided on your W-4. That form helps calculate the withholding; the W-2 summarizes at the end of the year what you earned and what was withheld. IRS · Tax Withholding (opens in a new tab)

When filing the return, the total tax is compared against the payments that count in your favor. If the payments are higher, there may be a refund; if they are lower, there may be a balance due. Therefore, looking only at how much you were refunded does not explain how much tax you actually owed. IRS · How a refund or balance is determined (PDF, in English) (opens in a new tab)

Additionally, there are refundable credits: if you meet their requirements, they can generate a refund even when you do not owe tax. Do not assume that you and your friend qualify for the same things. Eligibility is reviewed based on each person's actual situation. IRS · Refundable credits (in English) (opens in a new tab)

Same tax, two different outcomes

Imagine these two fictional cases. In both, the final federal tax is $4,200. To keep the comparison simple, we have excluded other payments, credits, and adjustments. We only change how much was paid in advance through withholdings.

Example data

Item	Case A	Case B
Withholdings	$5,000	$3,500
Assumed final tax	$4,200	$4,200
Result	$800 refund	$700 balance due

Case A paid $800 more than the final tax; Case B paid $700 less. Neither result, on its own, proves that one return was prepared better. The useful question is: “Were my income, payments and the benefits I qualify for reported correctly?”

W-2 boxes you should recognize

These names come from the IRS form itself. Do not add up all withholdings as if they were advances on the same tax. And if you find an incorrect name, salary, or amount, contact the employer to see if a corrected W-2 should be issued. IRS · Form W-2 and instructions, 2026 (PDF) (opens in a new tab)

Living in Florida does not eliminate federal taxes

Florida does not charge a state personal income tax and does not require a personal return for that tax. That does not eliminate federal obligations. If you worked or lived in another state as well, let us know when preparing your return so that case can be reviewed separately.

During a consultation, “I worked a few months outside Florida” can be more useful than a folder full of papers with no explanation. Make a short list of changes during the year: jobs, moves, marriage, separation or family changes. You will not have to remember everything on the spot.

What you can review before your next paycheck

The IRS withholding estimator allows you to review withholding for W-2 jobs and certain pensions and prepare a W-4 adjustment. Have recent pay stubs and your previous return on hand; if filing jointly, also have your spouse's information. It is advisable to review this when changing jobs or family status. The tool is not designed for nonresident alien taxpayers for tax purposes. IRS · Tax Withholding Estimator (opens in a new tab)

• Gather the W-2s from all your jobs; a return is reviewed with the complete picture.
• Write down what outcome you expected and why. Ask them to explain the difference between tax, withholdings, and refund.
• If you decide to change your withholding, submit the updated W-4 to your employer and check the next pay stubs.

You can start with our W-2 calculator for basic guidance. The result is a simplified federal estimate: it does not include all credits nor does it replace reviewing your complete return.
