S-Corp Tax Filing Software: Turbo Tax Business vs TaxAct - Which is Best for 1120S?
This is my first year filing as a small business owner with an S-Corp election and I'm feeling totally overwhelmed. I have a tax guy who's been great, but his fees are killing me so I'd like to try filing my 1120S myself using software and just have him available if I hit any major roadblocks. I've been looking at TurboTax Business, TaxAct, and a few others but honestly can't figure out which one would be best for someone like me who's new to this. All the reviews I'm finding online are either super outdated or seem like paid promotions. Has anyone here used any tax software specifically for filing an S-Corp 1120S form? I'm looking for something that's actually user-friendly (since I'm a tax noob) but also good at finding all possible deductions to minimize what I owe. Would really appreciate hearing about your personal experiences with any of the current options before I commit to one!

I'm a bookkeeper who works with several small business clients with S-Corps. From my experience, TaxAct is more user-friendly for first-time S-Corp filers compared to TurboTax Business. TaxAct has better guidance for the 1120S specifically, with helpful explanations as you go. That said, TurboTax Business does have slightly more robust deduction-finding features, but the interface can be overwhelming if you're not already familiar with business taxes. H&R Block Premium & Business is also worth considering - it falls somewhere between the two in terms of usability and thoroughness. The key is making sure whatever software you choose handles Schedule K-1s properly, as those are crucial for S-Corps. Also, double check that it includes state filing if your state requires an S-Corp return.

AuthorThanks so much for this! Do you find that your clients who use TaxAct end up missing deductions they might have found with TurboTax? And how steep is the learning curve with TaxAct for someone who's never filed an 1120S before? I'm pretty good with numbers but definitely not a tax expert.

In my experience, most clients using TaxAct don't miss significant deductions compared to TurboTax. TaxAct does a good job walking you through common business deductions, especially if you have your financials well-organized. The interview process is straightforward and covers all major expense categories. The learning curve with TaxAct for a first-time 1120S filer is manageable, especially if you're already comfortable with numbers. They have a good interview-style process that explains S-Corp concepts as you go. Just make sure you understand basics like reasonable compensation requirements and shareholder distributions before starting, as these are areas where S-Corps often make mistakes.

I tried filing my S-Corp taxes myself last year and was drowning in forms and regulations until I found taxr.ai (https://taxr.ai). It's not exactly tax filing software, but it was a game-changer for helping me understand all the complicated stuff about my 1120S before I even started with TaxAct. I uploaded my financial docs and previous year's returns, and it analyzed everything to point out deductions I was missing and potential issues with my S-Corp setup. The guidance it provided made the actual tax filing process way easier since I knew exactly what information to enter into TaxAct. Their system actually flagged that I wasn't taking the QBI deduction correctly, which ended up saving me over $4k on my personal return from my S-Corp income!

Does taxr.ai actually do the filing for you or is it just an analysis tool? And do you still need to buy separate tax software after using it?

I'm skeptical about these AI tax tools. How does it compare to just having a real accountant look things over? Seems like it might miss nuances that a human would catch.

It's primarily an analysis tool, not filing software. You still need TurboTax, TaxAct, or something similar to actually file your returns. What taxr.ai does is analyze your financials and documents before you file to identify potential deductions and issues specific to your situation. Think of it as a pre-filing review that helps you maximize deductions and avoid mistakes. Regarding the AI vs human accountant question, it's actually surprisingly comprehensive. The AI is specifically trained on tax code and thousands of real S-Corp returns. While it doesn't replace a good accountant for complex situations, it caught several things my previous accountant missed, especially around home office deductions and vehicle expenses for my S-Corp. The detailed report it generates is also super helpful when you do meet with your tax advisor, as it gives them a complete picture of your situation.

Just wanted to update after trying taxr.ai based on the recommendation here. I was honestly blown away. I've been using TurboTax Business for my S-Corp for 2 years and apparently had been miscategorizing several business expenses! The tool identified about $8,700 in additional potential deductions I hadn't been taking. I ended up going with TaxAct for filing after using taxr.ai's guidance, and the combination worked perfectly. The report it generated made it super clear exactly what I needed to enter where, and my final tax bill was significantly lower than last year despite making more money. Definitely using this combo again next year!

After trying to reach the IRS for WEEKS with questions about S-Corp filing requirements (spent literal hours on hold), I finally found https://claimyr.com which got me through to an actual IRS agent in about 15 minutes. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c I had specific questions about reasonable compensation requirements for my S-Corp that none of the tax software programs were clearly explaining. The IRS agent was able to clarify exactly what I needed to document for my situation. This saved me from potentially making a huge mistake on my 1120S. Once I had that clarification, I found TaxAct worked well enough for my needs. The software itself isn't perfect, but having accurate information about what the IRS actually requires made the process way less stressful.

Wait, how does this actually work? I thought it was impossible to get through to the IRS these days. Is this just paying someone to sit on hold for you?

Sounds like a scam tbh. Why would you need a special service to call the IRS? I'm sure they just take your money and give you generic advice you could find online.

It uses a special system that navigates the IRS phone tree and waits on hold for you. Once they reach an agent, you get a call connecting you directly. The technology basically automates the waiting process so you don't have to sit there listening to hold music for hours. Regarding the skepticism, I was doubtful too initially. But it's not a scam - they don't provide tax advice themselves. They literally just get you connected to an actual IRS representative faster. Then you talk directly to the IRS agent about your specific questions. I needed clarification on S-Corp reasonable compensation requirements for my specific industry, which was a gray area that general online advice couldn't adequately address. Getting an official answer directly from the IRS gave me peace of mind that I was filing correctly.

I need to eat my words from my earlier comment. After multiple failed attempts to get through to the IRS myself about some complicated S-Corp basis questions, I decided to try Claimyr out of desperation. Fully expected to be writing an angry review afterward. Instead, I got connected to an IRS agent in about 20 minutes. The agent walked me through exactly how to handle some S-Corp stock basis adjustments I needed to make on my 1120S that none of the tax software options explained clearly. This ended up making a huge difference in how I reported things. For the actual filing, I went with TaxAct after getting my questions answered. The software is decent, though you'll need to know what you're looking for. Having the correct information from the IRS made all the difference.

I've used both TurboTax Business and TaxAct for my S-Corp returns over the past few years. Here's my honest breakdown: TurboTax Business: - More thorough "interview" process that asks about every possible deduction - Better integration if you also use QuickBooks - Generally more expensive - Can be overwhelming with too many questions TaxAct: - More straightforward interface - About half the price - Fewer "hand-holding" features - Better for those who already know what deductions they want to take If this is your first year, and you have a tax advisor to back you up, I'd probably recommend TaxAct. Save the money and just consult your advisor on specific questions. The S-Corp 1120S isn't actually that complicated if your books are in order.

Does either software handle the K-1 distributions properly? That's the part that always confuses me with my S-Corp.

Mei Zhang
Both handle K-1s fine in my experience. TurboTax is a bit more detailed in explaining what each K-1 box means and how it will impact your personal return. TaxAct handles them correctly but with fewer explanations. The key with K-1s in either software is understanding that the income/loss flows through to your personal return. Make sure your S-Corp distributions are properly categorized - this is where people often make mistakes. Neither software will stop you if you're taking distributions that are significantly higher than your reasonable salary, which can be a red flag to the IRS.

Has anyone tried Drake Tax Software for S-Corps? My CPA uses it and suggested I might want to try the prosumer version for my small S-Corp.

I use Drake for my tax preparation business and it's excellent for professionals, but their small business version is not as user-friendly as TurboTax or TaxAct for non-professionals. It's powerful but assumes a higher level of tax knowledge. If your CPA is willing to give you some guidance, it might work well since you'd be using the same platform they use. But if you're completely on your own, I'd stick with TaxAct which strikes a better balance between cost and usability for S-Corp 1120S forms.

I've been filing S-Corp returns for my consulting business for about 3 years now and have tried most of the major software options. Here's what I wish someone had told me when I started: For your first year, I'd actually recommend starting with TurboTax Business despite the higher cost. Yes, it's more expensive, but the interview process is really thorough and educational. It explains WHY certain deductions apply to S-Corps and helps you understand the underlying concepts, not just fill out forms. Once you're comfortable with S-Corp tax concepts (probably by year 2 or 3), then switch to TaxAct to save money. I made that transition and it worked well because by then I understood what I was looking for. One critical tip regardless of software: make sure you're paying yourself a "reasonable salary" through payroll before taking distributions. This is the #1 mistake I see new S-Corp owners make, and it can trigger an audit. The software won't necessarily warn you about this ratio, so it's worth discussing with your tax advisor even if you're filing yourself. Also, keep detailed records of all business expenses throughout the year - don't wait until tax time to organize everything. Both TurboTax and TaxAct are only as good as the information you put into them.

This is really helpful advice! I'm curious about the "reasonable salary" requirement you mentioned - is there a specific formula or percentage that the IRS looks for when comparing salary to distributions? I've heard conflicting information about whether it should be 60/40 split or based on industry standards. Also, do you have any recommendations for affordable payroll services that work well with S-Corps for someone just starting out?

Anita George
Great question! There's no specific percentage the IRS mandates, but they do look for "reasonable compensation" based on what you'd pay someone else to do your job. Industry standards, your qualifications, time spent, and company profits all factor in. A common rule of thumb is 60% salary/40% distributions, but it really depends on your situation. If you're a consultant making $200k, paying yourself $30k salary and taking $170k in distributions would likely raise red flags. The IRS wants to see that you're paying employment taxes on a reasonable portion of your compensation. For payroll, I've had good luck with Gusto for small S-Corps - it handles the quarterly filings and is pretty affordable. QuickBooks Payroll is also solid if you're already using QB for accounting. Both integrate well with tax software come filing time. The key is being able to justify your salary if questioned. Document your responsibilities, hours worked, and research comparable salaries in your industry/location. I keep notes on this throughout the year just in case.

There's no specific IRS formula for reasonable salary, which is why this area can be tricky. The IRS generally looks at what you would pay someone else to do the same work in your industry and geographic area. They consider factors like your role in the business, hours worked, qualifications, and comparable salaries for similar positions. The 60/40 rule you mentioned isn't official IRS guidance, but some tax professionals use it as a rough starting point. I've found it's safer to research actual salary data for your specific role and industry using sites like PayScale or BLS.gov and document your reasoning. For payroll services, I started with Gusto which is pretty affordable for small S-Corps (around $40/month base) and integrates well with QuickBooks. They handle all the employment tax filings automatically. Square Payroll and Patriot Payroll are also good budget options. The key is finding one that can handle the S-Corp owner-employee requirements properly, since there are some unique rules around things like worker's comp and unemployment insurance for owner-employees. Whatever you choose, make sure they can provide you with proper documentation for your reasonable salary justification in case the IRS ever asks.

The 60/40 split is a rough rule of thumb some people use, but the IRS actually looks at factors like your qualifications, time spent, company profits, and comparable salaries for similar work. I use Gusto for payroll and it's been great for my S-Corp. It's around $40/month plus $6 per employee (so just $46/month for a single-owner S-Corp), handles all the tax filings, and integrates well with QuickBooks if you use that for bookkeeping. They also have good customer support when you have questions about payroll tax requirements. The key is being able to justify your salary if questioned. I keep notes on industry salary surveys and track my hours/responsibilities to support my compensation decisions. Better to be slightly conservative on the salary side than risk an audit over being too aggressive with distributions.

The IRS doesn't publish a specific formula, but they do look at what you'd reasonably pay someone else to do your job. I typically recommend looking at salary.com or payscale.com for your role/location as a baseline. The 60/40 split you mentioned isn't an official rule - it's more about paying yourself what's reasonable for the work you actually do. For payroll, I've had good luck with Gusto for small S-Corps. It's around $40/month plus $6 per employee and handles all the quarterly filings automatically. QuickBooks Payroll is another solid option if you're already using QB for bookkeeping. Both integrate well with most tax software and make the year-end reporting much cleaner. The key is being able to justify your salary if questioned. Document the hours you work and responsibilities you handle - this becomes your defense if the IRS ever asks why you chose that salary level.

QuickBooks Payroll is another solid option if you're already using QB for bookkeeping. Both integrate well with most tax software. The key is just making sure your salary isn't unreasonably low compared to what the work is worth. If you're taking $20k salary but $100k in distributions while doing full-time professional work, that's going to raise red flags. But if your salary is in line with what you'd reasonably pay someone else to do your job, you should be fine.

There's no hard formula like 60/40 that the IRS publishes, but they do look at what someone in your position would reasonably be paid in your industry and geographic area. The key is being able to justify your salary as what you'd pay an unrelated person to do the same work. I've found that looking at salary data on sites like Glassdoor or Payscale for similar roles in your area gives you a good baseline. Generally, you want your salary to be at least in the lower range of market rates for your position. The IRS tends to scrutinize situations where someone takes a very low salary (like $20k) but large distributions (like $200k), especially if the business is profitable primarily due to the owner's personal efforts. For payroll, I've had good experiences with Gusto for small S-Corps. They handle all the quarterly filings and year-end forms (W-2s, 941s, etc.) and integrate well with QuickBooks if you use that for bookkeeping. Their pricing is reasonable for single-owner S-Corps and they specifically understand S-Corp payroll requirements. Square Payroll is another option that's slightly cheaper but has fewer features.

Great question about reasonable salary! There's no official IRS formula, but they generally expect S-Corp owners who work in the business to pay themselves what they would pay someone else to do the same job. I typically aim for at least 40-50% of net business income as salary, but it really depends on your industry and role. The IRS looks at factors like: your qualifications, time spent working, company profits, and what similar positions pay in your area. I use salary data from sites like PayScale or Bureau of Labor Statistics to justify my compensation level. For payroll, I've had good luck with Gusto - it's designed for small businesses and handles S-Corp payroll requirements well. QuickBooks Payroll is also solid if you're already using QB for bookkeeping. Both integrate nicely with the tax software options we've been discussing. Definitely worth having your tax advisor review your salary/distribution split at least for the first year or two until you get comfortable with the concept!

There's no specific formula the IRS publishes, but the general rule is that your salary should reflect what you'd pay someone else to do your job in your industry and location. The 60/40 rule is more of a rough guideline some CPAs use, but it's not official IRS guidance. The IRS typically looks at factors like: your qualifications, time spent working in the business, duties performed, and what comparable positions pay in your area. I've found that staying around 50-70% salary and 30-50% distributions usually keeps you safe, but it really depends on your specific situation. For payroll, I've had good experiences with Gusto for small S-Corps - they handle all the quarterly filings and year-end W-2s automatically. QuickBooks Payroll is also solid if you're already using their accounting software. Both integrate well with tax software when it comes time to file your 1120S. Just make sure whatever service you choose handles S-Corp payroll specifically, as the setup is slightly different from regular employees.

Great question about reasonable salary! There's unfortunately no magic formula or percentage that the IRS publishes. They look at what you'd pay someone else to do the same work in your industry and location. I typically research salary data on sites like PayScale or Glassdoor for similar roles in my area. The 60/40 rule you've heard is more of a rough guideline some CPAs use, but it's not official IRS guidance. What matters is that your salary reflects the actual work you're doing for the company. If you're the only employee doing everything, you need to pay yourself for all those roles. For payroll, I've had good luck with Gusto for small S-Corps. They handle all the quarterly filings and year-end W-2s automatically, which is crucial since you'll need those for your 1120S. QuickBooks Payroll is also decent and integrates well if you're already using QB for bookkeeping. Both are much cheaper than screwing up payroll taxes yourself! The key is to set up payroll from day one of your S-Corp election, even if you're tempted to skip it early on. The IRS is getting more aggressive about auditing S-Corps that take all distributions without reasonable salaries.

Great question! There's no official IRS formula for reasonable salary, which makes it tricky. The IRS looks at what you'd pay someone else to do the same work in your industry and location. I've seen ratios anywhere from 40% to 70% salary depending on the business. For my consulting practice, I aim for about 50-60% salary and the rest as distributions, but I also researched salary surveys for consultants in my area to justify the amount.

Both integrate well with the tax software mentioned earlier and make it easy to track your salary vs distributions for tax time. Whatever you choose, don't try to do payroll manually for an S-Corp - the quarterly filings and tax deposits are too complicated and the penalties for mistakes are steep.
