This article reflects federal rules as of June 2026 and covers tax year 2025 (the returns filed in 2026). It notes state differences in general terms. Tax law changes often — confirm current figures with the IRS or a licensed professional before you file.
Quick Answer
It depends on your complexity. For tax year 2025, use TurboTax (or similar software) if you are a sole proprietor or single-member LLC with simple Schedule C income — it costs $0 to about $200. Hire a tax pro if you run an S-corp, partnership, have employees, owe in multiple states, or face an audit.
A small business owner filing under an April 15 deadline wants one thing: to pay the lowest legal tax without triggering an IRS notice. The honest answer is that TurboTax and a tax professional are not rivals so much as tools for different jobs — software shines on clean, single-owner returns, and a pro earns their fee the moment your return grows teeth, like an S-corp election, a business sale, or a state nexus problem.
The stakes are real, and the deadline is fixed. The average IRS penalty for failing to file on time runs 5% of unpaid tax per month, up to 25% — a fast, avoidable loss that can dwarf the price gap between software and a pro. One survey found roughly 22% of small business returns contain unclaimed deductions, money left on the table that the right help recovers.
Here is what you will learn:
- 💰 The real 2025–2026 price of TurboTax versus a CPA, with no hidden tiers.
- 🧾 Which business entities each option can actually file (and which it cannot).
- 📊 Three worked examples with real dollar figures you can copy.
- ⚠️ Seven costly mistakes that trigger penalties or missed deductions.
- ✅ A clear step-by-step plan for what to do before the deadline.
The Two Options, Side by Side
The choice is not really “TurboTax versus a human.” It is “do-it-yourself software versus a paid professional,” and each splits into sub-options. Understanding the parts keeps you from overpaying for help you do not need — or underpaying and missing a deduction worth more than the entire fee.
TurboTax is consumer tax software made by Intuit. You answer interview-style questions, and the program fills in your IRS forms and e-files them. It comes in a DIY version, a hybrid “Live Assisted” version where an expert reviews your work, and “Full Service,” where a pro prepares the whole return for you. The DIY path is cheapest but puts every decision on you.
A tax pro is a credentialed human: a CPA (Certified Public Accountant), an EA (Enrolled Agent, a federally licensed tax specialist), or a tax attorney. A pro does more than fill in forms — they plan ahead, spot industry-specific deductions, and can represent you before the IRS if you are audited. That representation is something DIY software cannot provide.
It helps to know that tax software is not accounting software. Programs like QuickBooks or Xero track your income and expenses all year. Tax software takes that finished bookkeeping and files one annual return. If your books are a shoebox of receipts, neither TurboTax nor a CPA can work magic cheaply — clean books come first, and messy books raise a pro’s fee fast.
What “Small Business” Means Here
“Small business” covers wildly different tax lives, and the right tool changes with each. A freelance writer with a laptop and a sole proprietor with five employees both call themselves small business owners, but their returns are nothing alike.
The key dividing line is your entity type, because it controls which IRS form you file. A sole proprietor or single-member LLC reports business profit on Schedule C, attached to a personal Form 1040. An S-corporation files its own Form 1120-S, a partnership or multi-member LLC files Form 1065, and a C-corporation files Form 1120.
The consequence of this is direct: the more complex your form, the weaker the case for plain DIY software. Schedule C is software’s home turf. Once you move to an entity-level return with payroll, basis tracking, and distributions, the value of a pro climbs sharply because one wrong entry can cost you thousands.
Which Situation Applies to You?
Tax help is never one-size-fits-all, so find your row before you read further. Match your business to the description below, then weigh the option it points to.
- Solo freelancer or single-member LLC, simple expenses, one state. Software is almost always enough. Free or low-cost tools handle your Schedule C well.
- Sole proprietor with home office, vehicle, and equipment depreciation. Software still works, but consider a “Live Assisted” tier or a one-time pro review to confirm your depreciation choices.
- S-corp or partnership owner. Lean toward a pro, or at minimum entity-capable software with expert help. Reasonable salary, basis, and K-1s get technical fast.
- You have employees or operate in multiple states. Strongly favor a pro. Payroll and multi-state apportionment are where software stumbles.
- You sold your business, raised money, hold crypto, or got an IRS notice. Hire a pro. These are planning and representation problems, not data-entry problems.
The reason this matters is cost-versus-risk. Paying a CPA $1,200 to file a simple solo Schedule C is overkill. Filing a first-year S-corp yourself in software to save $600 can cost far more if you set your salary wrong and the IRS reclassifies your distributions.
What TurboTax Costs in 2025–2026
Price is where many owners decide, so here are the real numbers for tax year 2025, not marketing ranges. TurboTax pricing rises as the April deadline nears, so the same product can cost more in April than in January.
For sole proprietors and single-member LLCs, TurboTax Premium runs about $129 federal plus $59 per state. The desktop Home & Business edition lists at $130 and includes five federal e-files plus one state download. Promotions in January often drop the online Premium price closer to $99.
For S-corps, partnerships, and C-corps, you need TurboTax Desktop Business, which lists at about $190 and includes five federal e-files. Note one limit that surprises people: TurboTax Business is Windows-only, with no Mac version, so Mac users must use a workaround or a different product.
If you want a human safety net inside the software, TurboTax adds expert help for a fee. Live Assisted and Full Service tiers cost more — often a few hundred dollars on top of the base — and Full Service has a pro prepare the entire return. Even then, TurboTax’s audit “support” is informational only and does not include someone representing you before the IRS unless you buy a separate Audit Defense add-on.
Cheaper Software Alternatives
TurboTax is not the only option, and for simple returns it is the most expensive. Knowing the alternatives can save you over $100 for the same Schedule C.
FreeTaxUSA files federal Schedule C returns for $0, charging only about $15.99 per state. It does not support S-corp, partnership, or C-corp returns, so it fits sole proprietors only. H&R Block sits in the middle, with a desktop Business version near $115 that includes unlimited tax-pro chat — a real edge over TurboTax’s paid-only expert help.
The consequence of ignoring these options is simple overpayment. A solo consultant in one state can file for under $20 with FreeTaxUSA versus roughly $188 with TurboTax Premium plus state. The next step: if you are a clean Schedule C filer, price-check the free and budget tools before defaulting to TurboTax.
What a Tax Pro Costs in 2025–2026
A professional costs more upfront, and the spread is wide. The fee depends on your entity, your bookkeeping quality, and your region. Knowing the ranges prevents both sticker shock and overpaying.
For a small business return, expect roughly $400 to $1,200 per year for routine preparation, and $2,500 or more for complex returns. A simple Schedule C handled by a pro often lands in the $400 to $700 range, while an S-corp or partnership return with K-1s costs more because of the added forms. H&R Block’s in-person service starts around $240 for sole proprietors and $280 for corporations.
The reason a higher fee can still be a bargain is what a pro finds and prevents. Reporting suggests CPAs uncover an average of $2,000 to $5,000 in missed deductions that software does not flag, plus they provide forward-looking planning — when to buy equipment, whether to elect S-corp status, how to time retirement contributions. The next step before hiring: ask for a flat-fee quote and confirm the pro has a valid PTIN in the IRS preparer directory.
Three Worked Examples (with Real Numbers)
Numbers make the choice concrete. Each example uses tax year 2025 figures and shows the math so you can copy it for your own situation.
Example 1: Maria, Freelance Designer
Maria is a single-member LLC in Florida (no state income tax) with $80,000 of net profit, a home office, and standard mileage. Her return is one Schedule C plus a Schedule SE for self-employment tax. Software is a clean fit.
Her self-employment tax is 15.3% on 92.35% of profit: $80,000 × 0.9235 × 0.153 = $11,303. She also claims the 20% qualified business income (QBI) deduction under Section 199A, worth roughly $16,000 off her taxable income. Filing with FreeTaxUSA costs her about $16 total; TurboTax Premium would cost roughly $188. A CPA would charge $400 to $700 for essentially the same result, so software is the rational choice — she saves the fee with no added risk.
Example 2: David, S-Corp Owner
David runs an S-corp in Texas and pays himself a salary plus distributions. His return is a Form 1120-S with a K-1, payroll filings, and shareholder basis tracking on Form 7203. This is where DIY gets risky.
If David sets a “reasonable salary” too low to dodge payroll tax, the IRS can reclassify distributions as wages and add back-taxes plus penalties — a hit that can exceed $5,000. A CPA charging $1,200 sets a defensible salary, tracks basis correctly, and plans next year’s distributions. Here the pro’s fee is cheap insurance against a costly reclassification, so David should hire one.
Example 3: Priya, Two-Partner LLC in Two States
Priya co-owns a consulting LLC taxed as a partnership, with clients in California and Oregon. Her return is a Form 1065 with two K-1s and multi-state income apportionment. Software handles single-state partnerships but stumbles on nexus.
California also charges an $800 minimum LLC franchise tax that is separate from the federal return and that tax software does not file for her. With income split across two states and a partner buyout pending, Priya pays a CPA about $1,800 — and avoids double-taxing the same income across state lines, an error worth far more than the fee.
Common Scenarios at a Glance
These three patterns cover most small business owners. Find the closest match and note where it points.
| Your Business Situation | The Smarter Choice |
|---|---|
| Solo freelancer, one state, simple expenses, profit under $200k | DIY software (FreeTaxUSA, TurboTax Premium); a pro is usually overkill |
| S-corp or partnership, K-1s, payroll, basis tracking | A tax pro, or entity software only with expert review attached |
| Multi-state nexus, business sale, audit notice, or crypto | A CPA or EA; software cannot plan or represent you before the IRS |
A second view helps when money is involved. The table below shows the cost-versus-risk tradeoff.
| If You Choose Software When You Shouldn’t | The Likely Consequence |
|---|---|
| Filing a first-year S-corp yourself to save the fee | Wrong “reasonable salary”; IRS reclassifies distributions, adds back-taxes and penalties |
| Skipping a pro on a multi-state return | Income taxed twice across states; missed credits worth more than the fee |
And the reverse mistake costs money too.
| If You Hire a Pro When You Don’t Need One | The Likely Consequence |
|---|---|
| Paying $700 for a clean solo Schedule C | You overpay by $500+ for a return software files for under $20 |
| Hiring a CPA only at tax time, never planning | You pay full price for filing but miss the year-round planning that justifies it |
The 2025 Tax-Law Wrinkle (OBBBA)
A new factor tilts the scale toward professional help this year. The One Big Beautiful Bill Act (OBBBA), signed in 2025, added and changed several deductions that take effect for tax year 2025. New rules mean new traps.
The law created temporary deductions, including ones for qualified tips, overtime pay, and car-loan interest, claimed on a new Schedule 1-A. Several of these provisions are temporary and carry income phase-outs and sunset dates — the IRS is still finalizing guidance on some details, so figures may change. This is exactly the kind of unsettled, rapidly evolving area where a pro who reads the regulations earns their fee.
The reason this matters for your software-versus-pro decision is the conformity question: your state may not follow these new federal deductions. Many states decouple from new federal write-offs, so a deduction you claim federally might not reduce your state tax at all. A pro confirms what your specific state allows; software may not flag the mismatch. The next step: if your 2025 income includes tips, overtime, or you bought a vehicle on a loan, confirm both the federal rule and your state’s conformity before filing.
Pros and Cons
Weigh both sides before deciding. Each point includes the “why” so you can apply it to your own case.
Pros of TurboTax / DIY software
- Low cost, because you pay $0 to about $200 instead of $400 or more for a pro.
- Speed and control, since you file on your own schedule without booking an appointment.
- Good guided deductions, as the interview prompts common write-offs like home office and mileage.
- Year-to-year import, which saves time because it carries last year’s data forward.
- E-file and refund tracking built in, so you see your result in real time.
Cons of TurboTax / DIY software
- No real representation, because audit “support” is informational and not someone speaking for you to the IRS.
- Missed strategic deductions, since software reacts to what you enter and cannot plan ahead.
- Weak on multi-state and entity nuance, which is where costly errors hide.
- Upsell prompts, because base prices climb fast once you add expert help or state filings.
- All risk on you, as a wrong entry is your liability, not the software’s.
Pros of a tax pro
- Real representation, since a CPA or EA can defend your return before the IRS.
- Strategic planning, because a pro models future moves like S-corp elections and equipment timing.
- Industry knowledge, which surfaces deductions software never asks about.
- Error and penalty protection, as a credentialed preparer signs the return and stands behind it.
- Time saved, freeing you to run the business instead of decoding forms.
Cons of a tax pro
- Higher cost, often $400 to $2,500+, which is overkill for simple returns.
- Scheduling, because good preparers book up near the deadline.
- Variable quality, since not every preparer is equally skilled — verify credentials.
- Less control, as you hand over your data and wait.
- Ongoing fees, because year-round planning costs more than one-time filing.
Do’s and Don’ts
A few habits protect you no matter which path you pick. Each carries a reason.
Do’s
- Do close your books before filing, because clean records cut both software errors and a pro’s fee.
- Do file an extension if you are not ready, since Form 4868 buys six months to file.
- Do verify any preparer’s PTIN, because only credentialed pros can represent you.
- Do separate business and personal accounts, as mixed records trigger audit risk and lost deductions.
- Do keep receipts for at least three years, since that is the usual IRS audit window.
Don’ts
- Don’t assume an extension delays payment, because tax owed is still due by April 15 or penalties accrue.
- Don’t file an S-corp yourself in year one, since salary and basis mistakes are expensive.
- Don’t ignore state franchise taxes, because software does not file them and states still bill you.
- Don’t reuse passwords on tax accounts, as credential-stuffing attacks target Intuit users.
- Don’t pick a preparer by price alone, since the cheapest can cost you in missed deductions.
Mistakes to Avoid
These specific errors cost small business owners real money every year. Watch for each.
- Setting an unreasonably low S-corp salary — the IRS reclassifies distributions as wages and adds back payroll tax plus penalties, often over $5,000.
- Filing late without an extension — the failure-to-file penalty is 5% of unpaid tax per month, up to 25%.
- Forgetting state franchise tax — California bills $800 minimum even on a money-losing LLC, separate from your federal return.
- Mixing personal and business expenses — disallowed deductions and a higher audit risk follow blurred records.
- Skipping shareholder basis tracking — without Form 7203, the IRS can disallow losses you tried to deduct.
- Assuming your state follows new federal deductions — many states decouple, so you overstate your state refund and owe later with interest.
- Treating an extension as a payment delay — interest and penalties pile up on unpaid tax even when you file in October.
- Choosing software that cannot file your entity — FreeTaxUSA and most free tools do not handle 1120-S or 1065, so you stall at the deadline.
What to Do Next
With the deadline fixed, work this short list in order. Each step removes a risk before April 15.
- Identify your entity and form — Schedule C, 1120-S, 1065, or 1120 — because that determines which tools can even file you.
- Get your books clean by closing the year in your accounting software and pulling a profit-and-loss statement.
- Match the tool to the job using the “Which situation applies to you?” section above.
- If filing yourself, buy software early to lock the lower price, and budget time for state filings.
- If hiring a pro, book now and confirm their PTIN in the IRS directory, then ask for a flat-fee quote.
- If you cannot finish in time, file Form 4868 by April 15, 2026, and pay your estimated tax to stop penalties.
- Call a professional the moment you hit an S-corp election, a sale, a multi-state issue, or an IRS notice — these are not DIY problems.

Frequently Asked Questions
Can TurboTax file an S-corp return?
Yes, but only TurboTax Desktop Business, not the Premium version. For tax year 2025 it lists near $190 and files Form 1120-S, but it is Windows-only and offers no built-in IRS representation if you are audited.
Is a CPA worth it for a small business?
Yes, when your return is complex. Reporting shows CPAs find an average of $2,000 to $5,000 in missed deductions and add year-round planning. For a simple solo Schedule C under $200,000, software usually costs far less for the same result.
How much does TurboTax cost for a small business in 2025?
About $129–$190 federal. Premium for sole proprietors runs roughly $129 plus $59 per state, while Desktop Business for entities lists near $190 with five federal e-files. Prices rise closer to the April deadline.
How much does a tax pro charge a small business?
Roughly $400 to $1,200 a year. Simple Schedule C returns often run $400–$700, while S-corps, partnerships, and complex multi-state returns can reach $2,500 or more depending on your bookkeeping and region.
Does tax software handle multiple states well?
No, not for complex nexus. Software can file one or two states, but multi-state apportionment and conformity issues are where it stumbles. If you have nexus in several states, a CPA usually saves more than the fee.
Can I file my business and personal taxes together?
Yes, for pass-through entities. Sole proprietors and single-member LLCs report Schedule C on the personal 1040. S-corps and C-corps file a separate return, then you report your salary and distributions on your personal return.
What is the tax filing deadline for 2026?
April 15, 2026 for most individual and Schedule C filers; S-corps and partnerships file Form 1120-S or 1065 by March 16, 2026. Filing Form 4868 extends the deadline to file, not the deadline to pay.
Does TurboTax provide audit representation?
No. TurboTax includes informational audit support only, where it explains your return. To have someone represent you before the IRS, you buy a separate Audit Defense add-on or hire a CPA, EA, or tax attorney.
Do I still owe state franchise tax if I use software?
Yes. Tax software files your federal and state income returns but does not file state franchise taxes or annual reports. States like California ($800 minimum) bill these separately through the Secretary of State or revenue agency.
Should a first-year business use a CPA?
Usually yes for entities, no for simple solos. A first-year S-corp or partnership benefits greatly from a pro who sets up salary, basis, and elections correctly. A first-year freelancer with simple expenses can safely use software.
What is the cheapest way to file a small business return?
FreeTaxUSA, at about $16 total for a sole proprietor filing one state Schedule C. It does not support S-corps or partnerships, so entity filers must use TurboTax, H&R Block, or a pro.
When should I switch from software to a tax pro?
When complexity arrives. Switch once you elect S-corp status, add a partner, hire employees, sell the business, owe in multiple states, or receive an IRS notice. These are planning and representation problems software cannot solve.
