No tax filing service can give you a larger refund than you are actually owed

The size of your refund is determined by your income, deductions, and tax withholding — not by which service files your return. TurboTax, H&R Block, TaxAct, and a tax professional will all calculate the same refund amount if they use the same information about your earnings and expenses. A service cannot legally create deductions you do not have or claim credits you do not may have access to for, no matter how much you pay them.

What differs between services is accuracy, speed, and whether they catch deductions you might miss on your own. A tax professional or more detailed software may find legitimate deductions or credits you overlooked — but that is about finding what you are actually owed, not about the service inflating a number.

Key Takeaways

  • Your refund amount is set by your actual income, deductions, and withholding, not by which filing service you choose.
  • A tax professional or detailed software can help you find deductions or credits you might miss, which may increase a legitimate refund.
  • Free filing services (IRS Free File, VITA) calculate refunds the same way as paid services — the difference is support and features, not the final number.
  • If two services give you different refund amounts, one has made an error in how it recorded your income or deductions.

What actually determines your refund size

Your refund is the difference between the total tax you paid during the year (through paycheck withholding or quarterly payments) and the total tax you actually owe based on your income. If you paid $4,000 in withholding and owe $3,200, your refund is $800. No filing service changes that math.

The only way to increase your refund is to reduce the tax you owe — which means finding deductions or credits that lower your taxable income. Common ones include the standard deduction (which everyone gets), child tax credits, education credits, or deductions for mortgage interest or charitable donations. A service can help you find these if you did not know about them, but it cannot invent them.

Where tax professionals and detailed software actually help

A tax professional or comprehensive software package may find deductions or credits that simpler tools miss. For example, if you are self-employed, you can deduct home office expenses, vehicle mileage, or equipment costs — but you have to know to report them. A tax professional will ask the questions that surface these. A basic online form might not.

Similarly, if you have a complex situation — rental income, investment losses, side business income, or dependents with their own income — a professional can structure your return to minimize tax legally. This might increase your refund, but again, it is because you are now reporting what you actually owe, not because the service is generous.

Free services like VITA (Volunteer Income Tax information) and IRS Free File offer the same calculation engine as paid services. The difference is that paid services often include phone support, more detailed guidance, and software that walks you through edge cases. If your situation is straightforward, the refund will be identical.

Why different services might show different refund amounts

If TurboTax tells you your refund is $1,200 and H&R Block tells you it is $900, one of them has made a data entry error or misunderstood your situation. This happens most often when:

  • You entered your W-2 income differently in each service (a typo in wages or withholding).
  • You claimed a deduction in one service but not the other.
  • One service asked about a credit you may have access to for and the other did not.
  • You made an error in how you described your filing status or dependents.

To find the error, go back through both returns side by side and check that income, deductions, and credits match exactly. The IRS will use whichever return you actually file, so accuracy matters more than which service you chose.

Red flags: services that promise unusually large refunds

Be cautious of any service that promises a refund larger than you expect without explaining where the extra money comes from. Legitimate tax services will show you exactly which deductions or credits they are claiming and why you may have access to. If a service cannot explain the difference, do not file that return.

Some services charge a fee to file and then offer to deduct that fee from your refund — meaning you receive less money, not more. Read the fine print about how fees are handled before you commit.

How to find deductions you might actually be missing

If you want to maximize a legitimate refund, start by listing your situation: Do you own a home? Do you have student loans? Did you donate to charity? Do you have children or dependents? Do you have medical expenses? Did you pay for education or job training?

Then cross-check against the IRS's list of common deductions and credits at IRS.gov. A tax professional can also review your situation in 15 minutes and tell you whether you are missing anything. Many offer a free initial consultation. That conversation might uncover a real deduction you overlooked — which would increase your refund legitimately.

Frequently Asked Questions

Can a tax professional get me a bigger refund than I would get filing myself?

Only if you are missing deductions or credits you did not know about. A professional cannot create deductions that do not exist. If your situation is straightforward — you have a W-2 job, no side income, and no major deductions — you will get the same refund either way. If you have a complex situation, a professional might find legitimate deductions you overlooked.

Is the IRS Free File refund smaller than what I would get from TurboTax?

No. IRS Free File and paid services use the same tax calculation rules. Your refund will be the same if you enter the same information. The difference is that paid services may offer more detailed guidance or phone support, not a different refund amount.

What if I file with one service and then file again with another?

The IRS will process whichever return reaches them first. If you file twice, the second return will be flagged as a duplicate and rejected. Do not file the same tax year twice. If you made a mistake on the first return, you can file an amended return (Form 1040-X) after the first one is processed.

Do tax services charge more if my refund is large?

Most do not. TurboTax, H&R Block, and TaxAct charge a flat fee based on which version you buy (basic, standard, or premium), not based on your refund size. Some tax professionals charge a percentage of the refund, so ask before you hire them.

Can I deduct the cost of tax filing software?

If you itemize deductions (rather than taking the standard deduction), tax preparation fees can be deducted as a miscellaneous expense, but only if your total miscellaneous expenses exceed a certain threshold. Most people take the standard deduction, so this does not explore to them. Check with a tax professional about your specific situation.
