If you're comparing Deduction and TaxAct, you're probably trying to figure out whether you still need to file your own taxes, or whether it's time for someone to do it for you.
TaxAct is DIY tax software. You answer questions, enter numbers, and the software maps your inputs to the right forms. It's been around since long, it's cheaper than TurboTax, and for straightforward returns, it works. Millions of people use it every year.
Deduction is a different product entirely. Taylor, CPAI is an AI tax accountant that handles document collection, return preparation, year-round planning, and filing, with returns reviewed by a licensed tax professional as a standard part of the process. You don't fill out forms. You don't enter numbers. You have a conversation, and your taxes get done.
These aren't two versions of the same thing. One is a tool you use to do your taxes. The other is a service that does your taxes for you.
Core Difference: TaxAct is DIY tax filing software. In contrast, Deduction is a tax firm and the creator of Taylor, CPAI, an AI tax accountant that provides year-round tax advice and prepares your return. Human professionals are involved throughout the process; every high-impact decision and your final return are reviewed by a licensed professional before filing.
Note: Deduction's 100% Accuracy Guarantee covers IRS interest and penalties resulting from errors in your prepared return. Terms apply. See Terms of Service.
DIY Tax Software vs. AI Tax Accountant
This is the fundamental distinction, and it shapes everything else about the comparison.
TaxAct: You Do the Work, Software Does the Math
TaxAct follows the model that's defined consumer tax filing for two decades. You sit down, answer questions about your income and deductions, enter numbers from your W-2s and 1099s, and the software calculates your return. It's an interview-style interface, the software asks, you answer, and forms get filled out behind the scenes.
TaxAct does this well, and at a lower price point than TurboTax. If you know what you're doing, or your taxes are simple enough that the interview catches everything, it's a reasonable tool.
But you're the one doing the work. You're responsible for entering the right numbers. You're responsible for knowing which deductions apply to your situation. You're responsible for catching the $0 cost basis on your 1099-B and manually correcting it so you don't overpay. The software calculates accurately based on what you give it. What you give it is on you.
Deduction: Taylor, CPAI Does the Work, a CPA Verifies It
Deduction works differently. You don't sit down with an interview. You text, call, email, or chat with Taylor, CPAI, and the AI handles the rest. Taylor collects your documents, processes your financial data, identifies issues like withholding shortfalls and cost basis discrepancies, prepares your return, and answers your tax questions year-round.
All returns are reviewed by a licensed tax professional before filing. You don't fill out forms. You don't enter numbers. You have conversations with your AI tax accountant, and a licensed tax professional stands behind the work.
The difference shows up most clearly when something is complicated. If your 1099-B shows a $0 cost basis on your RSU shares, TaxAct needs you to know that's wrong and manually enter the correct basis. Taylor, CPAI catches it automatically, prepares the Form 8949 adjustment, and the CPA verifies it before filing.
Who Each Product Is Built For
TaxAct
TaxAct is built for people who are comfortable filing their own taxes and want to spend less than TurboTax doing it. Their sweet spot is the middle market: too complex for the free tier, not complex enough (or not willing to pay enough) for a full-service solution.
TaxAct offers four tiers, Free, Deluxe ($29.99 federal), Premier ($49.99 federal), and Self-Employed ($69.99 federal), each targeting a different level of complexity. The Premier tier handles investment income, rental properties, and foreign accounts. Self-Employed covers Schedule C and 1099 income.
If your taxes involve a W-2 or two, some investment income, maybe a rental property, and you're willing to enter the data yourself, TaxAct is designed for your situation.
Where TaxAct gets less comfortable is equity compensation beyond basic stock sales. RSU cost basis correction, ISO exercise timing, AMT calculations, multi-lot tracking, these require knowledge the software doesn't supply. TaxAct can file the forms, but it can't tell you what should go on them for complex equity situations.
Deduction
Deduction is built for people whose taxes have grown beyond what they want to handle alone, or beyond what DIY software can reliably catch.
Tech employees with RSUs and stock options. Freelancers with 1099 income across multiple clients. Content creators with mixed income. People with rental properties, K-1 partnerships, and multi-state filing. Anyone currently overpaying a CPA or nervous that their DIY filing is missing something.
Taylor, CPAI handles all of it for $499 a year. This includes unlimited conversations with Taylor, year-round tax planning and advice, expert-reviewed federal and state filing, secure document storage in your Vault, and our 100% accuracy guarantee. This also includes ‘pass-through entities’, for example, if you have a LLC for a side hustle where the income passes through to your personal return.
Accuracy and Guarantees
TaxAct
TaxAct offers a $100,000 Accuracy Guarantee. If a TaxAct software error results in you paying a penalty or interest to the IRS, they will reimburse you for the difference of up to $100,000.
This is a guarantee, and it's stronger than what most DIY competitors offer. But it covers software errors only. If you enter the wrong cost basis, classify income incorrectly, or miss a deduction because you didn't know to look for it, that's a user error, and the guarantee doesn't apply.
With DIY software, user error is the primary risk. The software calculates correctly based on your inputs. The question is whether your inputs are correct.
Deduction
Deduction's 100% Accuracy Guarantee covers IRS interest and penalties if there's an error in your return. Because a licensed CPA reviews every return before it's filed, the scope of what's covered is broader, it's not limited to software calculation errors. The professional review is designed to catch the kinds of mistakes that DIY software puts on the user to avoid.
This is the fundamental difference in guarantee models: TaxAct guarantees its software's math. Deduction guarantees the accuracy of the complete return, because a human professional verified it.
Handling Complex Tax Situations
Equity Compensation
TaxAct can handle basic stock sales through Form 8949 and Schedule D. If your RSUs vested and you sold shares, you can enter the transactions in TaxAct's Premier tier.
But here's the issue: your 1099-B from E*Trade, Schwab, or Fidelity will likely show a $0 cost basis, because IRS regulations prohibit brokers from including the compensation income portion in the cost basis. If you enter the 1099-B as-is, you'll be taxed on the full sale price, including the income that was already taxed on your W-2. That's double taxation.
TaxAct doesn't automatically flag or correct this. You need to know the cost basis is wrong, calculate the correct basis (the fair market value at vesting), and manually adjust it. If you don't, you overpay. This is one of the most common and expensive mistakes tech employees make with DIY filing.
Taylor, CPAI can flag cost basis discrepancies by cross-referencing your W-2 and 1099-B, prepare the Form 8949 adjustment with the correct basis code, and have the tax professional verify the numbers match.
For ISO exercises, AMT calculations, NSO income reporting, and multi-lot cost basis tracking across different vesting dates, TaxAct offers the forms, but not the guidance. Taylor, CPAI handles the full picture.
Year-Round Planning
TaxAct is a filing product. You use it during tax season to prepare and file your return. Between filings, there's no advisory relationship, no ongoing planning, and no one to call when you have a tax question in August.
Xpert Assist provides CPA/EA access through October 31 of the filing year, but it's an add-on purchase, and it's focused on helping you complete your return, not ongoing tax planning.
Taylor, CPAI is available year-round. "Should I exercise these ISOs before year-end?" "How much should my next estimated payment be?" "I'm switching jobs, what happens to my unvested RSUs?" You ask whenever the question comes up. Your $499 covers the whole year.
Experience Comparison
Filing With TaxAct
You log in, choose your tier, and start the interview. TaxAct asks questions: filing status, dependents, income sources. You enter W-2 data (manually or via import, if your employer's EIN is in TaxAct's database). You add 1099s, investment transactions, deductions. The software calculates your return and shows your refund or balance due. You review, pay for the software, and e-file.
For simple returns, this takes 30–60 minutes. For complex returns with investment income, rental properties, or self-employment, it takes considerably longer, and the accuracy depends entirely on your data entry and tax knowledge.
Filing With Deduction
You chat with Taylor, CPAI: "I have RSUs vesting this quarter, a rental property, and some freelance income, what do you need from me?" Taylor automates document collection. You provide information naturally, no interview, no forms, no portals. Taylor processes everything, identifies issues, prepares the return. A CPA reviews and approves. You're done.
No software to learn. No forms to navigate. No hoping you entered the right cost basis an an AI tax filing tool.
When TaxAct Makes Sense
TaxAct is a solid choice if:
- Your taxes are straightforward, W-2 income, standard or itemized deductions, basic investment income
- You're comfortable doing your own taxes and understand the forms
- You want to spend less than TurboTax and don't need in-person support
- Your return doesn't involve complex equity compensation, multi-lot cost basis, or AMT calculations
- You don't need year-round tax planning or advisory
TaxAct is a good product for DIY filers. It has a strong accuracy guarantee for software errors, and it handles a wide range of tax situations. If you know what you're doing and your taxes aren't complex, there's nothing wrong with TaxAct.
When Deduction Is the Better Choice
Deduction is built for you if:
- Your taxes have grown complex, equity compensation, freelance income, rental properties, K-1s, multi-state filing
- You'd rather have your taxes handled than handle them yourself
- You want a licensed tax professional reviewing your return before it's filed, not as an add-on, but as a standard part of the service
- You need year-round advisory, not just a once-a-year filing tool
- You've been DIY filing and suspect you're leaving money on the table, missed deductions, incorrect cost basis, withholding gaps
- You want an accuracy guarantee that covers the complete return, not just software math
The jump from TaxAct to Deduction isn't a jump from one tax software to another. It's a jump from doing your taxes to having your taxes done, with professional oversight at every step.

Frequently Asked Questions about Deduction vs TaxAct
Here are comparative questions asked frequently about Deduction vs TaxAct:
Does TaxAct have a CPA review my return?
Not by default. TaxAct is DIY software, you prepare your own return. Xpert Assist (a paid add-on) provides access to CPAs and EAs who can answer questions while you file, but they don't independently review your complete return for accuracy the way Deduction's CPA team does.
What's the difference between TaxAct's $100K guarantee and Deduction's 100% Accuracy Guarantee?
TaxAct's guarantee covers software calculation errors, if the software does the math wrong, they'll pay up to $100,000. Deduction's guarantee covers IRS interest and penalties resulting from errors in your prepared return. Terms apply. Because a licensed CPA reviews every Deduction return before filing, the guarantee covers a broader scope, including the kinds of errors that come from human and AI preparation, not just software bugs.
Can TaxAct help me with tax planning during the year?
Not meaningfully. TaxAct is a filing product, you use it to prepare and file your return. Xpert Assist provides CPA access through October 31 of the filing year, focused on completing your return. For ongoing tax planning, estimated payment guidance, equity decision support, and mid-year questions, you'd need a year-round advisory relationship, which is what Taylor, CPAI provides as part of the $499 annual fee.
I've been using TaxAct for years, is switching hard?
Not at all. Taylor, CPAI collects your documents and builds your tax picture through natural conversation. You don't need to export data from TaxAct or learn a new system. Just start a conversation, share what Taylor asks for, and your AI tax accountant takes it from there. Most clients find the transition from "doing my taxes" to "having my taxes done" is the easiest part.
