Best Tax Software for Small Business in 2026: 5 Options Compared

Why Your Business Needs Tax Software in 2026

Filing business taxes is the one task owners put off the most - and the one where a mistake costs the most. Tax software for small business in 2026 does more than fill forms: it imports your 1099-NEC and 1099-K income, tracks vehicle and home-office deductions through the year, catches quarter deadlines and files federal and state returns electronically in about an hour.

For a sole proprietor filing Schedule C, the price difference between tools is large (from $0 to over $200), but every tool below handles a real business return correctly. The choice is really about how much guidance you want, whether you need entity returns (S-corp, partnership) and whether you want a human to review the file before it goes to the IRS.

How We Compared and Priced These Tools

Prices below are the publicly listed 2026 federal rates for the self-employed or business tier, checked in September 2026 from each vendor. State returns cost extra in most cases and are noted per tool. All five products are US-focused: if your business is in Vietnam, use them only for US-source income or US filings, and keep Vietnamese e-invoicing with a certified local provider (see our guide to e-invoice software in Vietnam).

TurboTax - Best Overall Guidance (Premium Price)

TurboTax Self-Employed lists around $129 federal (state around $59), and TurboTax Business for S-corp and partnership returns starts higher, around $190. It is the most polished interview-style product: it asks questions in plain English, imports W-2 and 1099 data from roughly 1.5 million employers and banks, and its deduction finder catches things you would miss. For a first-time Schedule C filer it is the least stressful option.

What you pay extra for: TurboTax Live (about $120 more) adds a CPA or enrolled agent who reviews your return before filing, and Full Service (around $389) hands the whole return to a professional. Audit support is included with a maximum-refund guarantee on paid tiers. If your return is simple, the same company's free edition covers basic W-2 income, but not business income.

H&R Block - Best Value with In-Person Backup

H&R Block Self-Employed Online lists around $115 federal (state around $49), and it is the strongest competitor to TurboTax at a lower price. Its free tier is more generous than TurboTax's (it includes unemployment and retirement income, not just W-2), and its paid plans include unlimited live chat plus AI Tax Assist.

The differentiator is physical: if you get an IRS notice, you can walk into an H&R Block office for help. Audit support is included, and Tax Pro Review (about $80 more) adds a professional review before filing. The interface is slightly less polished than TurboTax, and the self-employed questionnaire is not as deeply guided, but for a freelancer who wants a safety net it is often the smartest buy.

TaxAct - Budget-Friendly for Experienced Filers

TaxAct Self-Employed lists around $70-85 federal, with state around $45, and TaxAct Business covers S-corp, partnership and corporation returns online for roughly $160 - usually the cheapest entity-return option among the big names. Accuracy is guaranteed up to $100,000 on paid tiers.

TaxAct is built for people who know what Schedule C, depreciation and estimated taxes are. The interview is shorter and less hand-holding than TurboTax, import is good but not as automatic, and the interface feels dated. Choose it when you want a solid, cheaper return and do not need someone to hold your hand.

FreeTaxUSA - Best Value for Sole Proprietors

FreeTaxUSA charges $0 for federal filing (all forms, including Schedule C) and $14.99 per state - the lowest total cost of any major product for a self-employed filer. Deluxe, at about $8, adds priority phone support and a deduction-maximizer. There is no free phone support on the free tier and no polished interview, but the software handles nearly every IRS form.

For a sole proprietor on a tight budget, FreeTaxUSA is the rational default: the federal price is zero, accuracy is guaranteed up to $10,000 (or $100,000 on Deluxe), and you can file an S-corp or partnership return for far less than TurboTax Business. The trade-off is support - you mostly help yourself.

TaxSlayer - Budget Pick with Pro Access

TaxSlayer Self-Employed lists around $57-75 federal (state extra, about $39-45), making it the lowest-priced major brand that still offers access to a tax professional: SimplyFree is free, Classic covers W-2 and 1099, and Premium includes unlimited chat with a pro plus audit assistance. It is a frequent pick for military and gig-economy filers who want a human on call without TurboTax Live pricing.

TaxSlayer is less known and its interface is utilitarian, but for a freelancer comparing strictly on price-plus-support it beats H&R Block and TurboTax. Entity returns (S-corp, partnership) are handled in its higher tiers.

How to Choose: Match the Tool to Your Size

File free with FreeTaxUSA if you are a sole proprietor with straightforward income and are comfortable reading forms. Choose H&R Block Self-Employed (~$115) when you want live chat and the option of walking into an office. Choose TurboTax (~$129, plus Live if you want a CPA review) when guidance is worth more than the price difference. Pick TaxAct or TaxSlayer when you file S-corp or partnership returns and want to keep the bill under $200. If your books are messy or you had a large, unusual year, spend the money on a CPA instead of software - the review pays for itself.

Vietnam and SEA: What to Check Before Buying

All five tools are built for the US tax system. If you live in Vietnam and file a US return (for example a US LLC owned by a Vietnamese resident), check three things: (1) whether the tool accepts foreign addresses and non-US phone numbers for verification; (2) whether you actually have US-source income requiring a return - many owners over-file and pay software for nothing; (3) currency - you will pay in USD with an international card. For Vietnamese domestic obligations (VAT, PIT, e-invoicing under Decree 254/2026/NĐ-CP), none of these tools apply; use a certified local provider and keep your e-invoice records separate from your US tax files.

FAQ

Is there completely free tax software for self-employed?

Yes. FreeTaxUSA charges $0 for federal self-employed returns (all forms, including Schedule C) and only $14.99 per state. TaxSlayer SimplyFree is free for simple W-2 income but does not include Schedule C. TurboTax and H&R Block free tiers cover basic W-2 income only - not business income.

What is the cheapest way to file a Schedule C?

FreeTaxUSA at $0 federal plus $14.99 per state is the cheapest way to file a Schedule C return accurately. If you want phone or chat support with that filing, TaxSlayer Self-Employed (~$57-75) is the cheapest major option that includes access to a tax professional.

Do I need the business version for a side hustle?

No - if your side hustle is a sole proprietorship, the self-employed tier of any tool above handles Schedule C correctly. You only need the business version (TurboTax Business, TaxAct Business) if you file a partnership (1065), S-corp (1120-S) or corporation (1120) return.

Which tax software is best for an LLC?

It depends on how the LLC is taxed. A single-member LLC taxed as a sole proprietorship files Schedule C with any self-employed tier above. An LLC taxed as an S-corp needs entity-return support: TurboTax Business or TaxAct Business, with TaxAct usually cheaper.

Can I use US tax software if my business is in Vietnam?

Use US tax software only for US-source income and US filings. It does not handle Vietnamese VAT, PIT or e-invoicing obligations, which are regulated by Vietnamese law (e-invoices under Decree 254/2026/NĐ-CP) and must be done through a certified local provider.

Our Recommendation for Small Business in 2026

Start with FreeTaxUSA if price matters most - $0 federal for a Schedule C return is hard to beat, and the forms are complete. Choose H&R Block Self-Employed when you want live support and a physical office as backup. Choose TurboTax Self-Employed when you want the most guided experience and are comfortable paying for it. Whichever you pick, keep your bookkeeping current all year (our bookkeeping guide covers tools that make this easier) so filing season takes one evening, not one panic.
