If you're a solo consultant billing on 1099s, the “best” tax software depends entirely on how complicated your income already is — not which brand has the biggest marketing budget. For a straightforward Schedule C with clean books, FreeTaxUSA is the cheapest predictable option, running roughly $16 to $81 total depending on how much human support you want. For consultants who want guided software with live expert help built into the price, H&R Block Self-Employed is the stronger fit at $179 for federal plus one state. For anyone whose real problem is messy deduction tracking rather than filing itself, Keeper's $199-a-year plan earns its keep. And once you're eyeing an S-corp election or already running payroll, ordinary consumer tax software — TurboTax, H&R Block, even TaxAct's DIY tier — stops being the right tool; that's CPA territory.
This guide isn't a feature list. It's a routing system built around a consultant complexity ladder, because a $45,000 side-hustle consultant, a $90,000 full-time solo, and a $180,000 agency-of-one need three different stacks, and paying for the wrong one either wastes money or leaves deductions on the table.
Why “small business” tax software isn't quite the right lens for consultants
Most tax-software marketing talks about “self-employed” or “small business” filers as one bucket. Solo consultants are a specific slice of that bucket: usually no employees, usually one or two 1099 income streams, usually a home office and some mileage, and increasingly a decision point about whether an S-corp election makes sense once profit clears roughly $60,000 to $80,000. The software that handles that well isn't necessarily the one with the biggest ad spend.
There's also a filing-year wrinkle worth naming up front. Most readers using this guide in mid-2026 are wrapping up an extended tax year 2025 return or getting organized for tax year 2026. The two years use different numbers under the One, Big, Beautiful Bill: the standard deduction for tax year 2025 (filed in 2026) is $15,750 single or married filing separately, $31,500 married filing jointly, and $23,625 head of household. For tax year 2026 (filed in 2027), it rises to $16,100 single or married filing separately, $32,200 married filing jointly, and $24,150 head of household. Mixing those up is an easy way to misjudge your own numbers before you even open the software, as of mid-2026 per the IRS.
A few other numbers move mid-year and are easy to get wrong if you're doing manual math instead of letting software track dates. The IRS standard mileage rate for business use was 70 cents a mile for all of 2025, rose to 72.5 cents from January through June 2026, and rose again to 76 cents from July through December 2026. Using one flat rate for the whole year will misstate your deduction. Software that timestamps mileage entries handles this automatically; a spreadsheet built from memory usually doesn't.
One more baseline number worth knowing before you pick software: the IRS generally requires a return once net self-employment earnings hit $400, and for 2026 earnings the Social Security portion of self-employment tax applies up to a $184,500 wage base, with no ceiling on the Medicare portion. Our self-employment tax guide walks through how Schedule SE actually calculates that, as of mid-2026.
The consultant complexity ladder: route by your numbers, not by brand
Instead of ranking software by star ratings, it's more useful to place yourself on a ladder of complexity and see what the actual 12-month cost looks like at each rung — one state, no employees, no S-corp unless noted.
Persona A: the $45,000 side-hustle consultant
One W-2 job plus consulting income reported on a single Schedule C, one state, no depreciation, no multi-state issues. This is the cleanest possible case, and it's exactly where the cheapest tools shine. If the return is supported, Cash App Taxes runs $0 federal and $0 state. FreeTaxUSA's free federal plus a $15.99 state return brings the same return to $15.99 total. Want a chat option in case something looks off? FreeTaxUSA's Deluxe Support adds $7.99, landing at $23.98. Paying $179 for H&R Block Self-Employed or $122.98 for TaxSlayer Self-Employed at this complexity level is mostly paying for hand-holding you may not need yet.
Persona B: the $90,000 full-time consultant
Full-time Schedule C income from 1099-NEC and possibly 1099-K sources, home office deduction, business mileage, software subscriptions, quarterly estimated payments, one state. This is where the calculus shifts. FreeTaxUSA Pro Support — a licensed tax pro on standby — brings the one-state total to $80.98, still well under the guided competitors. If your books are messy and you're worried about missed deductions more than filing mechanics, H&R Block Self-Employed at $179 (with live expert help built into the price) or Keeper Standard at $199 a year (which tracks deductions year-round, not just at filing time) both start to look worth the premium.
Persona C: the $180,000 agency-of-one
High-profit solo consultant, possibly using subcontractors, possibly issuing 1099-NEC forms of their own, and realistically evaluating an S-corp election. This is the point where the routing logic changes entirely: you're no longer shopping for the cheapest Schedule C software, you're shopping for entity support and a paper trail a CPA can review. If you're still filing Schedule C with no payroll, TaxAct's Sole Proprietor product at $109.99 plus a state fee (TaxAct doesn't post a flat online state price, so confirm it at checkout) is the most entity-aware option among the DIY tools. If an S-corp election is already in place, TaxAct's Form 1120-S product runs $169.99 plus state, or $299 plus $69 for all states with Full Service; Keeper's Business plan, built for S-corp and partnership filers, runs $1,199 a year. None of that replaces a CPA's judgment on whether the election, the salary you're paying yourself, and the state-level treatment actually hold up — that's a conversation to have before you file, not after.
One-state Schedule C: the real 12-month cost, side by side
| Option | Federal | State | One-state total |
|---|---|---|---|
| Cash App Taxes (if supported) | $0 | $0 | $0 |
| FreeTaxUSA, Free filing | $0 | $15.99 | $15.99 |
| FreeTaxUSA, Deluxe Support | $0 | $15.99 + $7.99 | $23.98 |
| FreeTaxUSA, Pro Support | $0 | $15.99 + $64.99 | $80.98 |
| TaxAct Sole Proprietor (DIY) | $109.99 | additional, unposted | $109.99+ |
| TaxSlayer Self-Employed | $74.99 | $47.99 | $122.98 |
| H&R Block Self-Employed Online | $130 | $49 | $179 |
| Keeper Standard (annual) | included | included | $199/year |
| TurboTax (self-employed range) | $0-$149 | additional | varies by form |
TurboTax is listed as a range on purpose. Intuit's own pricing page notes the final price depends on which forms your return actually needs and can change by the time you file, so it isn't fair to quote it as a single number. As of mid-2026.
FreeTaxUSA: the default for clean Schedule C books
FreeTaxUSA's federal filing is free even for self-employment income — it covers Schedule C, 1099-NEC and 1099-MISC income, and the itemized deductions many consultants need, according to the company's own pricing page, as of mid-2026. The catch, and it's a small one, is that state filing costs $15.99 flat, with optional add-ons: Deluxe Support at $7.99 for priority chat and phone help, Pro Support at $64.99 for access to a credentialed tax professional, and Audit Defense at $19.99. Avoid the pay-with-refund option if you can — it adds a $24.99 fee just to skip entering a card number.
Best for: consultants with reasonably organized books who mainly need accurate forms rather than a guided interview. Skip it if: you want a polished, walkthrough-style interface, live chat included by default, or you're filing your first-ever Schedule C and want more built-in hand-holding — FreeTaxUSA assumes some comfort navigating deduction questions on your own.
H&R Block Self-Employed: guided software with human help already in the price
H&R Block's Self-Employed Online tier runs $130 federal plus $49 per state, for $179 all-in on a single-state return, as of mid-2026. That's real money compared to FreeTaxUSA, but it buys something specific: live expert help is included across H&R Block's Deluxe, Premium, and Self-Employed online tiers, not sold as a separate upgrade. The product is explicitly built around Schedule C — home office, mileage, and business expense categories are front and center rather than buried.
One nuance worth knowing before you pick a tier: H&R Block itself says that if your Schedule C income has no business expenses attached, Deluxe at $65 plus $49 state may be the cheaper correct fit; Self-Employed is for when you're actually claiming deductions against that income. Skip Self-Employed if: you have no expenses to claim, or you're strictly price-optimizing and comfortable without built-in live help.
Keeper: built for deduction tracking, not just April
Keeper's pitch is different from the rest of this list — it's less “tax software” and more a year-round expense tracker that also files. The Standard plan runs $199 a year and includes federal and state e-filing, deduction tracking linked to up to 10 financial accounts, receipt uploads, a maximum-refund guarantee, and audit protection, per Keeper's pricing page as of mid-2026. Premium runs $399 a year, and Business, built for S-corp and partnership filers, runs $1,199 a year. There's also an “Only Deductions” plan at $20 a month that explicitly does not include filing, which is easy to misread if you're comparing plans quickly.
Best for: consultants whose actual weak point is missed deductions or disorganized receipts, not the mechanics of filing itself. Skip it if: your books are already clean in a bookkeeping platform like QuickBooks or FreshBooks and you only need annual filing — paying an ongoing subscription for tracking you don't need is the wrong trade at that point.
TaxAct: the clearest on-ramp to S-corp and partnership filing
TaxAct's consumer self-employed products are competitive, but its real differentiator for growing consultants is a genuine business-entity ladder. Sole Proprietor filing (Schedule C or F) runs $109.99 plus a state fee that TaxAct doesn't post as a flat online rate — confirm it at checkout rather than assuming. Add Xpert Assist for $154.99 plus state if you want a tax expert available during the process, though TaxAct discloses that Xpert Assist review doesn't include a full source-document review, so it's guidance, not an audit of your paperwork.
Once you cross into entity territory, TaxAct's Form 1120-S product runs $169.99 plus state for S-corp filing, with a Full Service option at $299 plus $69 for all states, as of mid-2026. Best for: consultants already filing Schedule C who expect to move toward an S-corp or partnership return in the near term. Skip it if: you just need the simplest, cheapest Schedule C filing with zero entity complexity — TaxAct's advantage doesn't really show up until you need 1120-S or 1065 support.
TurboTax and TaxSlayer: where each one actually fits
TurboTax is the household name for a reason — strong guided flow, broad document import, and, in the Premium self-employed tier, automatic 1099-NEC capture and a year-round tax estimator after filing. The honest problem is pricing: Intuit's own site quotes DIY at $0 to $149 federal, Expert Assist at $89 to $209 federal, and Expert Full Service starting around $100 to $200 depending on promotions, with the final number depending on which forms your specific return needs, as of mid-2026. That range makes TurboTax hard to budget for in advance, and it's easy to get upsold mid-return if a form isn't covered at the tier you started on. It's a reasonable pick if you value the interface and import tools enough to pay a premium for them; it's not the pick if price predictability matters more.
TaxSlayer's Self-Employed tier sits in the middle of this list at $74.99 federal plus $47.99 state, or $122.98 all-in for one state, as of mid-2026. It's a fair budget alternative to H&R Block if you want more structure than FreeTaxUSA's bare-bones flow without paying TurboTax or H&R Block prices. Skip it if you're strictly chasing the lowest possible number — FreeTaxUSA still undercuts it for straightforward returns.
Cash App Taxes: free filing, with one real caveat
Cash App Taxes advertises fully free federal and state filing, no paid tiers, and says it has processed more than 12 million returns at $0, as of mid-2026. For a genuinely simple consultant return — one Schedule C, one state, no depreciation — that's hard to beat on price. The caveat is that Cash App's public materials don't lay out a clear, exhaustive list of unsupported forms or situations, so multi-state returns, prior-year amendments, and more unusual Schedule C asset treatment should be treated as unverified until you've confirmed your specific situation is supported inside the product itself. Best for: the simplest possible solo consultant return. Skip it if: your return has any edge case you're not sure about — there's no paid upgrade path or live support tier to fall back on if the free product doesn't fit.
Skip DIY software entirely if...
- You have income or a filing requirement in more than one state
- You've elected or are seriously considering S-corp status for the first time
- You run payroll for yourself or anyone else
- You have significant asset depreciation, Section 179 elections, or equity/RSU income
- You have foreign income or foreign accounts
- Your OBBBA treatment — tip or overtime provisions, bonus depreciation retroactive to January 19, 2025, or similar — is genuinely unclear for your situation
None of the software above is designed to replace that judgment call, and none of it should be asked to.
Where tax software sits in your financial OS
Tax software lives in the Foundation layer of a solo financial stack — it's the compliance layer, not the growth layer. It works best when it's fed clean numbers from a bookkeeping system rather than being asked to reconstruct a year of receipts from a bank statement in April. If your books aren't already organized, pairing whichever filing tool you choose with a proper bookkeeping platform — see our QuickBooks review or FreshBooks review for solo operators — does more for your tax outcome than switching software brands ever will. For the mechanics of the self-employment tax itself, our self-employment tax guide walks through Schedule SE, and our breakdown of the 1099-K threshold change covers exactly what triggers a form versus what you still owe regardless. If you're mapping the whole stack from banking to taxes, the Solo Financial Stack Blueprint is the place to start.
Bottom line
There's no single “best” tax software for consultants — there's a best fit for your complexity level this year. If your Schedule C is clean and you're comfortable filling in your own numbers, FreeTaxUSA's free federal filing and $15.99 state fee is the hardest combination to beat. If you'd rather pay for guided software with live help already baked in, H&R Block Self-Employed at $179 earns its price. If deductions, not filing, are your actual weak spot, Keeper's $199-a-year plan solves a different problem than the others on this list. And the moment payroll, an S-corp election, or multi-state income enters the picture, the right move is routing to TaxAct's entity products or, better, a CPA who can review your specific numbers before you file — software can calculate the math, but it can't tell you whether your $55,000 “reasonable salary” will hold up.
