S-Corp questions for single-member, single-employee situations

Thanks for this info! I've been wondering about the retirement options specifically. With a Solo 401(k), what's the maximum I can contribute as both employer and employee? Is it better than a SEP IRA for a single-person S-Corp? Also, do you recommend any specific payroll services that make quarterly payroll easier?

For 2025, you can contribute up to $23,000 as an employee deferral to a Solo 401(k), plus catch-up contributions of $7,500 if you're 50 or older. As the employer, your business can contribute up to 25% of your compensation, with total contributions capped at $69,000 ($76,500 with catch-up). This is generally better than a SEP IRA for most S-Corp owners because you get both contribution types. I've found Gusto to be excellent for quarterly payroll. It automatically handles all the tax filings and deposits, plus it's very straightforward for single-employee situations. Other good options include OnPay and SurePayroll which are both designed with small businesses in mind.

That sounds interesting. Does it help with calculating quarterly estimated taxes too? I always seem to either overpay or underpay and end up with penalties.

I'm a bit skeptical about automated tax tools for S-Corps since the rules are pretty nuanced. Does it actually give advice that's personalized enough? Can it handle special situations like if you have rental properties or other income streams flowing through your business?

Yes, it actually does handle quarterly estimated tax calculations! It looks at your historical income patterns and projects them forward, then recommends quarterly payment amounts that help you avoid both underpayment penalties and overpaying throughout the year. The personalization is surprisingly comprehensive. You can input additional income streams, including rental properties, investments, and other business activities. It then creates a complete tax projection that accounts for all these factors. I was skeptical too until I saw how it identified specific court cases relevant to my industry that defined "reasonable compensation" standards. It's definitely more sophisticated than the typical tax calculator tools.

How does this actually work? Do they just call the IRS for you? Couldn't I just do that myself and save whatever they charge?

Yeah right. Nobody gets through to the IRS in 15 minutes. Last time I called I waited over 2 hours and then got disconnected. This sounds like one of those services that just takes your money and does nothing you couldn't do yourself.

They use a technology that navigates the IRS phone system and holds your place in line, then calls you when they've reached an agent. So you're not doing anything different than calling yourself, except you don't have to wait on hold for hours. I was definitely skeptical too! I've literally never gotten through to the IRS in less than an hour, and most times I just give up after being on hold forever. The difference is their system is constantly dialing and navigating the phone tree, which somehow gets priority in the queue compared to individual callers. I don't know exactly how it works technically, but I can tell you I spoke with an actual IRS representative who answered all my S-Corp questions in detail.

Do you think it's necessary to have a local accountant who you can meet with in person? Or have you had good experiences with remote accountants who specialize in S-Corps? Looking for recommendations since there aren't many specialists in my rural area.

I've been working with a remote S-Corp specialist for the last three years and actually prefer it to my previous local accountant. Everything is handled through a secure portal where I upload documents, and we do video calls quarterly to discuss strategy. Remote accountants who specialize in specific business structures often have more expertise than general local CPAs in my experience. The key is finding someone who works with a lot of businesses similar to yours. I found mine through a Facebook group for freelance consultants, and several members had used and recommended her. She works with clients nationwide but specializes in S-Corps for consultants and service businesses. Much better than trying to find a specialist in a rural area!

Yes, you file Form 1120-S for the corporation which generates a Schedule K-1. That K-1 information then gets reported on your personal Schedule E, which becomes part of your Form 1040 filing. You'll also have your W-2 wages from the S-Corp on that same 1040. Your salary ratio of $70,000 on $126,000 profit (about 55%) is actually right in the typical "reasonable" range for most service businesses. It's unlikely to raise red flags with the IRS. The people you see online paying very low salaries (like 20-30% of profits) are taking a much more aggressive position that could invite scrutiny. Your accountant gave you solid advice on this one!

Thanks so much for explaining! That makes a lot more sense now. I was getting lost in all the different forms and schedules. I appreciate the confirmation on my salary ratio too. I kept seeing people online talking about paying themselves like $30k salary on $150k of business income, and I was worried I was leaving money on the table. Good to know I'm in a reasonable range that shouldn't cause issues with the IRS.

This is really helpful advice! I'm actually in a similar situation - just converted my freelance graphic design business to an S-Corp about 6 months ago and I'm still figuring out the best practices. The monthly routine idea sounds great for staying on top of things instead of scrambling at year-end. Quick question about your reasonable compensation documentation - do you update that spreadsheet throughout the year or just annually? I've been saving job postings when I come across them, but I wasn't sure how frequently I should be researching salary ranges to support my compensation decisions. Also, did you find any particular resources or websites that were most reliable for finding comparable salary data for your industry? I've been using some of the big salary sites but wasn't sure if there were better sources specifically for documenting reasonable compensation for S-Corp purposes.

I update my reasonable compensation spreadsheet twice a year - once in January when I'm doing tax planning for the year ahead, and again in October before year-end planning. This gives me enough current data without making it feel like a constant chore. For reliable salary data, I've found the Bureau of Labor Statistics (BLS.gov) to be the gold standard since it's government data that the IRS would respect. Their Occupational Employment and Wage Statistics are really detailed by location and industry. I also use PayScale and Glassdoor, but I make sure to note the source and date for each data point in my spreadsheet. One tip that my S-Corp accountant shared - when you're documenting your research, also note what benefits a comparable employee would receive (health insurance, retirement contributions, etc.) since those factor into total compensation. This helped justify my salary level when I was accounting for the fact that my S-Corp pays for my health insurance and retirement contributions that a typical employee would get as additional benefits. The key is just being consistent and thorough with your documentation. Even if your salary ends up being questioned, having that research file shows you made a good faith effort to determine reasonable compensation based on market data.
