C-corp to S-corp conversion - what happens to previous year's earnings?
So I've been operating my small business as a C-corporation since I started it back in 2020. We did pretty well in 2023 and the company retained about $78,000 in profits that stayed in the business account. I didn't pay myself any formal salary or run payroll last year since I was reinvesting everything back into growing the business. Now I'm in the process of converting to an S-corp for 2024 (just filed Form 2553 last month) because my accountant said it would be more tax advantageous given my current situation. But now I'm confused about what happens to that money that was earned while we were still a C-corp. If the conversion goes through, would that $78K from 2023 automatically pass through to me as income for 2024 tax purposes? Or is it still considered C-corp money that was already taxed at the corporate level? I'm trying to plan ahead for my personal taxes and want to make sure I understand the implications of this conversion correctly.

This is a really important distinction to understand. The money earned while you were a C-corporation in 2023 will NOT pass through to you when you convert to an S-corporation in 2024. Those earnings were already subject to tax at the corporate level as C-corporation income. When you convert from C to S, only the income earned AFTER the conversion date is treated as pass-through income. The previously earned profits from your C-corporation days remain in what's called "Accumulated Earnings and Profits" (AE&P) account. If you want to distribute that $78K to yourself after becoming an S-corp, it would generally be treated as a dividend from your C-corporation days, not as pass-through income.

•What if they distributed the money to themselves before the conversion? Would that avoid the double taxation issue or create other problems?

•Taking distributions before converting to an S-corp could be a good strategy in some cases, as it would be treated as a dividend from your C-corporation at that time. You'd pay personal income tax on the dividend, but you'd avoid having it trapped in the AE&P account that carries forward to the S-corporation. However, distributing the money has its own implications. You'd need to carefully consider your overall tax situation, including dividend tax rates versus your personal income tax rate, and whether you actually need that cash personally versus keeping it in the business. There can also be accumulated earnings tax concerns if the IRS believes a C-corporation is retaining earnings beyond business needs just to avoid shareholder taxes.

I went through this EXACT situation last year. Super confusing until I used https://taxr.ai to analyze my corporate bylaws and conversion docs. The software clearly showed me how previous C-corp retained earnings are handled post-conversion and gave me a customized distribution strategy that saved me thousands. I was specifically worried about getting hit with that double taxation nightmare but they walked me through everything and basically laid out a roadmap for handling the retained earnings.

•So is this like AI for tax stuff? I'm in a similar situation but my business is smaller. Would it help with a smaller C-corp conversion with only about $35k in retained earnings?

•I'm skeptical about these AI tax tools. Do they actually understand the specific state-level implications? I'm in California and they have all sorts of weird rules about entity conversions that even my accountant struggles with sometimes.

•For smaller businesses, it's actually perfect since the AI can analyze your specific situation regardless of size. The tool is designed to handle both simple and complex scenarios, so $35k or $350k, it'll give you tailored guidance either way. Regarding state implications, this is actually where the tool really shines. It includes full state-level analysis for all 50 states, including California's specific quirks with entity conversions. I'm in New York which has its own complexities, and the software provided state-specific guidance alongside the federal analysis. It specifically highlighted some FTB (Franchise Tax Board) considerations I hadn't even thought about.

Wanted to update after trying taxr.ai from the recommendation above. It was super helpful for my situation! I uploaded my 2023 corporate docs and conversion paperwork, and it gave me a detailed report showing exactly how my retained earnings would be treated. The coolest part was the distribution timing strategy it recommended - apparently there's a way to minimize the tax hit by structuring certain distributions before finalizing the conversion. Wish I'd known about this tool months ago!

If you're still struggling with IRS questions about your conversion, don't waste time on hold forever. I used https://claimyr.com to actually get through to an IRS agent about my S-corp election questions. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was shocked but I got through to someone in like 15 minutes when I'd been trying for DAYS on my own. The agent walked me through some issues with my Form 2553 that would have delayed my conversion if not caught early. Totally worth it when you're dealing with time-sensitive entity conversion issues.

•Wait, how does this actually work? Do they just call the IRS for you or what? I'm confused about what the service actually does.

•Yeah right. The IRS has ridiculous wait times this year, especially for business tax departments. I find it hard to believe any service could magically get you to the front of the line. Sounds like snake oil to me.

•They don't call the IRS for you - they use a system that monitors the hold queues and then calls you when they've secured a place in line and an agent is about to be available. It's like having someone wait on hold for you, and then they bridge you directly with the IRS when an agent picks up. It's definitely not snake oil. The reason it works is because they're constantly dialing and using technology to navigate the phone tree and maintain connections across multiple lines simultaneously. Think of it as a "priority pass" for the IRS phone system. They're just using technology to solve the hold time problem that drives everyone crazy.

Ok I have to eat my words about Claimyr. After my skeptical comment I decided to try it anyway since I was desperate to talk to someone about my S election timing issues. Got through to the IRS Business & Specialty Tax line in about 20 minutes when I'd been trying unsuccessfully for over a week. The agent confirmed that my previous C-corp earnings could potentially trigger a built-in gains tax if distributed incorrectly after conversion. Saved me from making a costly mistake with my distribution timing. Sometimes it pays to be wrong I guess!

Just a warning based on my experience - watch out for Form 8832 vs Form 2553 confusion! My accountant filed the wrong form for my conversion and it messed up the timing of everything. Make sure you're using Form 2553 specifically for the S election. I ended up with an extra year as a C-corp because of this mistake and it cost me thousands in corporate taxes I could have avoided.

•Thanks for the heads up! I double checked and we definitely filed the 2553. But now I'm paranoid - is there any way to confirm the IRS has actually processed it correctly? My accountant said we should just wait for the acceptance letter but that makes me nervous based on your experience.

•You can actually call the IRS Business & Specialty Tax Line (800-829-4933) and ask them to check the status of your S election. They can tell you if it's been received, if it's pending, or if there are any issues. Don't just wait for the letter because if something went wrong, you want to know ASAP so you can fix it before tax deadlines. I learned this the hard way - waited 3 months for a letter that never came, only to find out they never received our form because it was sent to the wrong address. If I'd checked earlier, I could have resubmitted in time.

Something nobody's mentioned is the reasonable compensation issue after you convert. The IRS really scrutinizes S-corps that don't pay reasonable salaries to owner-employees. Since you didn't take any salary in 2023 as a C-corp, make sure you establish a reasonable salary for yourself in 2024 as an S-corp. The IRS loves to audit S-corps with owners taking all profit as distributions and little/no salary to avoid payroll taxes.

•How do you determine what's "reasonable" though? Is there some formula or percentage?

•There's no exact formula, but the IRS looks at what you'd pay someone else to do your job. They consider factors like your industry, geographic location, responsibilities, hours worked, and experience level. A good rule of thumb is to research what similar positions pay in your area - you can use sites like PayScale or Glassdoor as benchmarks. Many tax professionals suggest aiming for at least 40-60% of your total compensation as salary vs distributions, but it really depends on your specific situation. The key is being able to justify your salary amount if questioned. Document your reasoning and keep records of comparable positions/salaries in your industry and location.

One thing I'd add to the discussion about retained earnings - make sure you understand the "built-in gains tax" that can apply to converted S-corps. If your C-corp had unrealized gains on assets when you converted, those gains could be subject to corporate-level tax if you sell those assets within 5 years of conversion. This doesn't directly affect your $78K of cash retained earnings, but if your business has appreciated assets (equipment, real estate, inventory, etc.), you'll want to factor this into your planning. The built-in gains tax is designed to prevent companies from converting just to avoid corporate tax on pre-conversion appreciation. Also, keep detailed records of your asset values at the conversion date - you'll need this information for years to come. Your accountant should help you prepare a "built-in gains statement" as part of the conversion process.

•This is really helpful information about the built-in gains tax! I hadn't considered this aspect at all. My business has some equipment that's probably worth more now than when I bought it in 2021. Should I be getting formal appraisals of everything, or is there a simpler way to document the values at conversion? Also, does this 5-year rule reset if I make additional asset purchases after becoming an S-corp, or does it only apply to assets owned during the C-corp days?
