Online tax software calculates the same refund as the IRS would — the software itself doesn't make your refund bigger
The refund you receive depends on what you earned, what you paid in taxes, and what deductions or credits you're may have access to to. TurboTax, H&R Block, TaxAct, and other online services are calculators that follow IRS rules. They don't negotiate with the IRS or find money the agency missed. If you use one service instead of another, your refund stays the same.
What changes between services is the price you pay to file, the speed of getting your refund, and how much hand-holding you get along the way. Some services cost nothing if your income is below a threshold. Others charge $60 to $200 depending on how complex your return is. A few will advance you part of your refund before the IRS deposits it — but that's a loan, not a bigger refund.
The only way to change your actual refund is to report different income, claim deductions you didn't claim before, or find a credit you missed. A tax professional — whether you pay them through an online service or hire them separately — might spot something you overlooked. But the software itself is neutral.
Key Takeaways
- All major online tax services use the same IRS tax tables and rules, so they calculate the same refund amount for the same return.
- The difference between services is filing cost, refund speed, and whether they offer a refund advance loan.
- A refund advance is a short-term loan against your expected refund, not an increase to what the IRS owes you.
- You can change your refund only by reporting different income, claiming additional deductions, or finding a credit you missed.
- Free filing through IRS Free File or a service's free tier produces the same refund as a paid tier of the same service.
How refund advances work and what they cost
Some online services and tax preparation companies offer a refund advance — a loan that deposits money into your account within one to three business days, before the IRS sends your actual refund. The loan amount is usually between $250 and $3,000, depending on your expected refund and the lender's rules.
You repay the loan when the IRS deposits your refund. The cost is a fee, typically $15 to $50, plus interest that varies by lender. TurboTax, H&R Block, and some tax preparation chains offer this through partner lenders. It is not a bigger refund — it is borrowed money that you repay from your refund.
A refund advance makes sense only if you need cash before the IRS processes your return. Standard refund timing is 21 days if you file electronically and choose direct deposit. If you can wait, the advance costs you money for no benefit.
Free filing tiers versus paid tiers at the same service
Most major online services offer a free version for simple returns — usually W-2 income only, no business income or rental property. The paid versions unlock support for Schedule C (self-employment), Schedule E (rental income), itemized deductions, and other forms.
The refund calculation is identical between the free and paid versions of the same service. You are not paying for a bigger refund; you are paying for access to forms and features. If your return qualifies for free filing, using the free tier saves you money without changing what you receive from the IRS.
The IRS also runs IRS Free File, a program that offers free filing through participating tax software companies for households earning under a certain threshold (usually around $79,000 per year, though it varies). These are genuine free options with no upsell — the IRS pays the companies to offer them.
Why different services show different estimated refunds during filing
As you enter your information into any tax software, the program estimates your refund in real time. You might see a different estimate in TurboTax than in H&R Block, even though you entered the same numbers. This usually means one service caught a deduction or credit the other didn't prompt you for, or you entered information differently between the two.
The most common cause is missing information. If you didn't tell one service about a dependent, education expenses, or a charitable donation, it won't include that deduction. The other service might have asked the question more directly. Once you fill in the same information in both, the estimates converge.
Another cause is how the software interprets your situation. Some services ask more detailed questions about your job, investments, or life changes. The more detail you provide, the more deductions and credits the software can find. This is not the software being smarter — it is you providing more complete information.
What a tax professional can find that software might miss
A human tax preparer — whether you hire one independently or through an online service that offers professional review — can spot deductions and credits that software prompts might miss. Examples include home office deductions for self-employed people, energy-efficient home improvements, adoption credits, or education credits you didn't know existed.
Some online services offer a "review" or "audit defense" add-on where a tax professional checks your return before filing. This costs extra ($50 to $150 typically) and might catch something that increases your refund. But the software itself doesn't do this — a person does.
If you have a complex return — multiple income sources, investment losses, rental property, or a major life change — paying for professional review or hiring a tax preparer separately might be worth the cost. For a straightforward W-2 return, the software alone usually finds everything.
State refunds and how they differ from federal refunds
Most online services file both your federal and state returns. Your state refund is calculated separately using your state's tax rules, which differ from federal rules. Some states have different tax rates, different deductions, or different credits than the IRS.
One service might calculate a larger state refund than another if the software interprets your state's rules differently or prompts you for information the other service didn't ask about. But again, this is about completeness of information, not the service being better. Once you provide the same information to both, the state refund should match.
State refund timing also varies. Federal refunds typically arrive within 21 days of e-filing. State refunds can take 4 to 12 weeks depending on the state. Some states offer direct deposit; others mail a check.
Comparing services by cost, speed, and features instead of refund size
Since all services calculate the same refund for the same return, your choice should be based on what you pay to file, what features you need, and whether a refund advance is available. TurboTax and H&R Block are the most widely used and offer the most add-ons, but they also charge more. TaxAct is cheaper for basic returns. IRS Free File is the lowest cost if you may have access to by income.
The table below shows the starting price and key features of major services. Remember that the refund amount itself does not change between them — only the cost to file and the extras you get along the way.
| Service | Free tier | Lowest paid price | Refund advance available | Direct deposit timeline |
|---|---|---|---|---|
| TurboTax | W-2 only, no itemizing | $60–$120 depending on complexity | Yes, $250–$3,000 | 21 days standard |
| H&R Block | W-2 only, no itemizing | $50–$110 depending on complexity | Yes, $250–$3,000 | 21 days standard |
| TaxAct | W-2 only, no itemizing | $25–$85 depending on complexity | Yes, $250–$1,500 | 21 days standard |
| IRS Free File (various providers) | Full federal return, income limit ~$79,000 | N/A | Varies by provider | 21 days standard |
Frequently Asked Questions
Can I file with one service and get a bigger refund than if I filed with another?
No. The refund amount is determined by your income, deductions, and credits — not by the software. If two services calculate different refunds for the same return, it means you entered different information or one service prompted you for details the other didn't ask about. Once you provide identical information to both, they calculate the same refund.
Does paying for a premium tax service increase my refund?
Paying for a premium tier unlocks more forms and features, but it doesn't change your refund if your return is simple. If you have a complex return and the premium tier prompts you for deductions you missed, it might increase your refund — but that is because you reported more information, not because the paid version is better at calculating.
What is a refund advance and should I use one?
A refund advance is a short-term loan that deposits money into your account within a few days, before the IRS sends your actual refund. You repay it from your refund when it arrives. It costs $15 to $50 in fees plus interest. Use it only if you need cash urgently; otherwise, it costs you money for no benefit.
If I use IRS Free File, do I get a smaller refund than if I paid for software?
No. IRS Free File and paid software calculate the same refund. The difference is cost and features. Free File is limited to simpler returns, while paid software handles more complex situations. If your return qualifies for Free File, you save money without losing anything.
Can a tax professional find deductions that software misses?
Yes. A human tax preparer might spot deductions or credits that software prompts don't ask about, especially for complex returns with self-employment income, rental property, or major life changes. Some online services offer professional review for an extra fee. For straightforward W-2 returns, software alone usually finds everything.
