7 Best Software For S Corp Taxes (Form 1120-S) In 2026
Filing an S-Corp return (Form 1120-S) is more complex than a standard 1040. You're dealing with shareholder distributions, reasonable compensation rules, K-1 schedules, and specific IRS requirements that personal tax software simply can't handle. Choosing the best software for S corp taxes can save you hours of frustration, and potentially thousands in costly filing mistakes.
At TaxesToday, we prepare S-Corp returns for small business owners every day. Our CTEC-certified preparers have 15+ years of experience navigating the details of Form 1120-S, so we know exactly what these returns demand. That hands-on expertise also means we know what to look for in tax software, where each platform excels and where it falls short for real-world S-Corp filers.
Whether you're considering a DIY approach this year or simply want to understand your options before deciding between software and a professional preparer, this guide breaks down seven of the top-rated S-Corp tax software platforms for 2026. We'll cover pricing, features, ease of use, and the types of S-Corp owners each one suits best, so you can make a confident, informed decision for your business.
1. TaxesToday
When it comes to finding the best software for S corp taxes, the honest answer is that software alone has real limits. TaxesToday is not a DIY platform. It is a professional tax preparation service staffed by IRS-registered, CTEC-certified preparers with over 15 years of hands-on experience filing Form 1120-S returns for S-Corp owners across California and nationwide.
What you get for S corp taxes
TaxesToday handles your complete Form 1120-S preparation, from calculating shareholder basis and reasonable compensation to generating accurate K-1 schedules for each shareholder. Your preparer reviews every line of the return against your actual business financials, not a generic software wizard hoping you entered the right numbers. Returns are e-filed securely once reviewed and approved, and your preparer remains available for follow-up questions after filing.
Working with a certified preparer means a second set of expert eyes reviews your return before it reaches the IRS, which directly reduces the risk of errors that trigger audits or penalties.
Who it fits best
Small S-Corp owners who want accurate, done-for-you filing without the overhead of a large accounting firm will find TaxesToday fits their situation well. If you are a single-member LLC that elected S-Corp status, a two or three shareholder business, or a self-employed professional running payroll for yourself, this service is built for you. It also works well if your business had a complex tax year, such as shareholder changes, distributions alongside salary, or a first-year S-Corp election.
Your preparer can also assist if you need to file an amended Form 1120-S or handle prior-year S-Corp returns that were never filed, so you can get fully caught up on your IRS compliance.
What to prepare before you start
Gathering the right documents upfront makes the process faster and keeps your costs predictable. You will want to have these ready before your session begins:
- Profit and loss statement for the tax year
- Balance sheet as of year-end
- Payroll records showing W-2 wages paid to shareholder-employees
- Prior-year Form 1120-S (if applicable)
- Shareholder ownership percentages and any changes during the year
Pricing basics
Pricing at TaxesToday is transparent and straightforward, with no surprise add-on fees for standard state filings or e-filing. Your final cost depends on the complexity of your return, including the number of shareholders, whether additional state filings are needed beyond California, and whether amended or back-year returns are involved.
You can reach out directly for a quick quote before committing to anything. For most small S-Corp owners, the cost of a professional preparer is also a deductible business expense, which makes the investment more manageable come next tax season.
2. TurboTax Business
TurboTax Business is a desktop-only Windows application designed specifically for business entity returns, including Form 1120-S. It is a separate product from the personal TurboTax versions, so make sure you download the correct edition before you start.
Form 1120-S and S corp capabilities
TurboTax Business walks you through Form 1120-S preparation using a step-by-step interview format. It generates K-1 schedules for each shareholder automatically based on the ownership percentages you enter, and it covers common S-Corp deductions such as depreciation, home office, and business vehicle expenses. The software also handles built-in gains tax and excess net passive income calculations if your S-Corp converted from a C-Corp.
TurboTax Business does not support personal state returns, so if you also need to file an individual state return alongside your S-Corp return, you will need a separate product for that.
Who it fits best
TurboTax Business works best for S-Corp owners with relatively straightforward returns, meaning a single business entity with clean bookkeeping, consistent shareholders throughout the year, and no multi-state filing complexity. If you are comfortable using guided tax software and have a working understanding of your business financials, the interview format will feel manageable without a professional alongside you.
What you need to file smoothly
Before opening the software, gather your year-end profit and loss statement, balance sheet, payroll records showing shareholder W-2 wages, and last year's return. Having your shareholder basis calculations ready separately will save real time, since TurboTax Business does not automatically track basis across filing years.
Pricing and add-ons
TurboTax Business typically retails around $170 to $190 for the federal return only. State business returns cost extra and are purchased as a separate add-on within the software, so factor that into your total before buying.
3. TaxAct Business
TaxAct Business is a desktop download product that supports Form 1120-S filings alongside other business entity returns. It has built a reputation as a budget-friendly alternative to TurboTax Business while still covering the core requirements for most S-Corp returns.
Form 1120-S and S corp capabilities
TaxAct Business handles Form 1120-S preparation through a guided interview process. It automatically generates Schedule K-1 forms for each shareholder based on ownership percentages you input, and it covers common deductions including depreciation, vehicle use, and home office expenses. The software also supports multi-state filings more cleanly than some competitors, making it a stronger pick if your S-Corp operates across state lines.
TaxAct Business does not automatically track shareholder basis year over year, so you will need to maintain that calculation separately and bring it to your filing session.
Who it fits best
TaxAct Business suits cost-conscious S-Corp owners who have straightforward returns and clean financial records. If you already know your way around a basic profit and loss statement and have filed Form 1120-S before, the guided interview format will feel familiar and manageable. It is less well-suited for S-Corps with shareholder changes mid-year, built-in gains situations, or complex multi-entity structures.
What you need to file smoothly
Gather these items before you open the software to avoid stopping mid-return:
- Year-end profit and loss statement and balance sheet
- Payroll records showing W-2 wages paid to shareholder-employees
- Prior-year Form 1120-S and depreciation schedules
- Shareholder ownership percentages and any mid-year changes
Pricing and add-ons
TaxAct Business typically runs $109 to $120 for the federal return. State business returns cost extra as a separate purchase, so factor that in when you are comparing your total cost against other options for the best software for S corp taxes at your budget.
4. H&R Block Business
H&R Block Business is a desktop software product available for Windows that handles Form 1120-S alongside other business entity returns. It carries the H&R Block brand reputation for guided, user-friendly tax preparation, though the Business edition targets small business owners rather than individuals filing personal returns.
Form 1120-S and S corp capabilities
The software covers the core Form 1120-S requirements you would expect from a full business filing product. It generates K-1 schedules for shareholders, handles standard business deductions, and supports depreciation schedules for business assets. Each section uses a question-and-answer interview format, which reduces the chance of skipping required fields as you work through your return.
H&R Block Business does not track shareholder basis automatically, so bring your own basis calculations to the filing session rather than expecting the software to handle it.
Who it fits best
This product suits S-Corp owners who already use H&R Block for personal returns and want a consistent experience across both individual and business filings. It works best for returns with stable shareholder structures and clean bookkeeping, rather than complex situations involving mid-year ownership changes, built-in gains calculations, or multi-state compliance requirements.
What you need to file smoothly
Having your documents organized before you open the software keeps the process moving without frustrating stops. Prepare your year-end profit and loss statement, balance sheet, W-2 payroll records for shareholder-employees, and your prior-year Form 1120-S. You will also need your shareholder ownership percentages confirmed and any depreciation carryforward schedules from the prior year.
Pricing and add-ons
Federal pricing typically runs $89 to $110, making H&R Block Business one of the more affordable options when comparing the best software for S corp taxes at this price tier. State business returns cost extra as separate add-ons, so factor that into your total before purchasing.
5. Intuit ProConnect Tax Online
Intuit ProConnect Tax Online is a cloud-based professional tax software designed for accountants and tax preparers, not DIY filers. If you are an S-Corp owner working with a CPA or enrolled agent, there is a reasonable chance your preparer already uses this platform to handle your Form 1120-S filing.
Form 1120-S and S corp capabilities
ProConnect Tax Online supports full Form 1120-S preparation, including K-1 generation for each shareholder, built-in gains tax calculations, and multi-state apportionment. Because it is built for professionals, the platform assumes the user has tax knowledge, so you will not find the guided interview format that consumer-facing products offer. Instead, preparers work directly through form-based data entry, which gives them more control and flexibility over complex return situations.
ProConnect Tax Online connects directly with QuickBooks Online, so if your bookkeeper already maintains your books there, your preparer can pull data into the return without manual re-entry, which reduces errors significantly.
Who it fits best
This platform fits accounting professionals and tax preparers who handle multiple S-Corp clients rather than individual business owners filing their own returns. If you are an S-Corp owner trying to find the best software for S corp taxes on your own, ProConnect is not the right tool for you. It is built for the professional side of the table.
Workflow and integrations to expect
ProConnect integrates tightly with QuickBooks Online and other Intuit products, making it a natural fit inside an existing Intuit ecosystem. Your preparer can manage document collection, e-signatures, and e-filing from within a single platform, which speeds up the overall preparation workflow and reduces back-and-forth.
Pricing approach
Intuit prices ProConnect on a per-return basis, meaning your preparer pays for each return filed rather than a flat annual license. Costs are not publicly listed on a fixed schedule, so your preparer's pricing to you will reflect their per-return cost plus their service fee.
6. Drake Tax
Drake Tax is a professional-grade desktop software used primarily by independent tax preparers and small CPA firms. It handles a wide range of return types, and its Form 1120-S support is well-regarded among preparers who need both reliability and speed across a high volume of returns.
Form 1120-S and S corp capabilities
Drake Tax covers the full Form 1120-S filing workflow, including K-1 generation for each shareholder, built-in gains tax calculations, and depreciation schedules. The platform takes a form-based data entry approach rather than a consumer-style interview wizard, which means preparers can move through complex returns faster once they know the software. It also supports multi-state filings without requiring separate state add-on purchases in most subscription tiers.
If you are looking for the best software for s corp taxes from a preparer's perspective, Drake Tax is frequently cited for its speed and stability across high-volume filing seasons.
Who it fits best
Drake Tax suits independent tax preparers and small accounting firms who handle multiple S-Corp clients each filing season. This is not a self-service tool for individual business owners preparing their own returns. If you are an S-Corp owner, Drake Tax is relevant to you primarily as the platform your preparer may use rather than something you would purchase yourself.
Workflow and multi-return setup
The software is built around efficient multi-client management, with features like return status tracking, batch printing, and e-filing queues that help preparers handle large caseloads without losing track of individual clients. Importing prior-year data is straightforward within Drake, which reduces re-entry work across filing seasons.
Pricing approach
Drake Tax offers annual subscription pricing rather than per-return fees, which makes it cost-effective for preparers filing a high volume of returns. The cost is absorbed by your preparer and reflected in their service fee to you.
7. CCH Axcess Tax
CCH Axcess Tax is a cloud-based professional tax platform built by Wolters Kluwer and used primarily by mid-size and large accounting firms. It represents the high end of professional tax technology, combining enterprise-level compliance tools with cloud collaboration features that smaller platforms cannot match.
Form 1120-S and S corp capabilities
CCH Axcess Tax handles full Form 1120-S preparation, including K-1 generation for all shareholders, multi-state apportionment, built-in gains tax, and complex depreciation schedules. The platform is built to handle high-complexity S-Corp returns without the workarounds that consumer-grade or mid-tier professional software sometimes require. Preparers work through form-based data entry with deep diagnostic checking that flags potential errors before the return is submitted.
If your S-Corp has multiple shareholders, cross-state operations, or significant asset activity, CCH Axcess Tax gives your preparer the tools to handle that complexity without cutting corners.
Who it fits best
This platform fits large accounting firms and enterprise tax departments that manage hundreds of business returns each filing season. As an S-Corp owner searching for the best software for s corp taxes, CCH Axcess is not something you would purchase or use directly. It is relevant to you if your accounting firm already operates on this platform, which signals a high level of professional infrastructure behind your return.
Workflow, controls, and collaboration
CCH Axcess Tax supports multi-user workflows with built-in review controls, so multiple team members can work on your return with clear sign-off steps before filing. Document management and e-signature collection are built into the platform, reducing the back-and-forth that slower, paper-based processes create.
Pricing approach
Wolters Kluwer prices CCH Axcess Tax through custom firm-level contracts rather than public per-return pricing. Your accounting firm absorbs the licensing cost and factors it into their service fees to you.
Your next step
Every option on this list serves a different type of S-Corp owner. If you run a straightforward single-shareholder business with clean books and prior filing experience, consumer desktop software like TaxAct Business or TurboTax Business can handle your return at a reasonable cost. If your return involves shareholder distributions, mid-year ownership changes, or multiple states, the risk of a DIY mistake outweighs the savings on software fees. That is where a professional preparer makes a real difference.
Finding the best software for S corp taxes sometimes means recognizing that the right tool is a certified professional rather than a program. TaxesToday prepares Form 1120-S returns for small business owners across California and nationwide, with transparent pricing and no hidden fees. Your return gets reviewed by an IRS-registered, CTEC-certified preparer before it ever reaches the IRS. Get your S-Corp taxes done right this year and file with confidence.
