How can my family's C-Corporation investment company avoid Personal Holding Company (PHC) tax and Accumulated Earnings Tax (AET) legally?
Title: How can my family's C-Corporation investment company avoid Personal Holding Company (PHC) tax and Accumulated Earnings Tax (AET) legally? 1 Our family office recently restructured as a C-Corporation to manage our investments, but I'm concerned about triggering Personal Holding Company (PHC) tax and Accumulated Earnings Tax (AET). My grandfather built a successful manufacturing business that we sold five years ago, and now we're primarily focused on managing that capital through various investment vehicles. The CPA who handles our family's personal returns warned me that our current structure might create tax issues since most of our corporate income comes from dividends, interest, and capital gains. Apparently, if more than 60% of our adjusted ordinary gross income is from these passive sources, and five or fewer individuals own more than 50% of the value of the corporation's stock (which is definitely our case), we could trigger PHC tax. Similarly, we're retaining significant earnings within the corporation (around $9.2 million currently) for future investment opportunities, which could trigger AET issues. I'm trying to understand what legitimate strategies we can implement to avoid these additional tax burdens while maintaining the protection and structure of a C-Corporation. We're not looking for aggressive tax schemes, just practical solutions that other family offices or UHNW individuals might use to navigate these particular tax challenges.

12 The PHC tax and AET are definitely concerns for family investment companies structured as C-Corps. Here are some practical strategies to consider: For PHC tax avoidance, you need to either: 1) keep passive income below the 60% threshold, or 2) adjust your ownership structure. You could introduce active business operations that generate sufficient non-passive income. Think management services, consulting, or operating businesses that complement your investment activities. Some family offices provide investment advisory services to other families or entities for reasonable fees, which counts as active income. For AET concerns, you need to demonstrate that retained earnings serve reasonable business needs. Document specific, feasible investment plans with timelines and capital requirements. Consider a formal dividend policy that distributes a reasonable percentage of earnings while retaining capital for documented growth opportunities. Many families also explore creating multiple entities with different purposes - perhaps some investments in pass-through entities while keeping the C-Corp for specific strategic investments or operating activities.

•7 This is helpful advice, but I'm confused about what qualifies as "reasonable business needs" for AET purposes. If we're planning to acquire a business in the next 3-5 years that would require substantial capital, would documenting this plan be sufficient? Also, what's the threshold for how much we can accumulate before the IRS gets suspicious?

•12 Documentation of specific acquisition plans would absolutely help justify retained earnings. The more detailed your plans (target industry, price range, timeline, etc.), the stronger your position. There's no fixed dollar threshold - it's about demonstrating that accumulations are reasonable relative to your documented business needs. The "reasonable needs" test considers factors like your industry, growth plans, economic conditions, and working capital requirements. Having a written capital expenditure plan approved by your board is extremely valuable. Many investment companies also document contingency reserves for potential investment opportunities, which can be justified if you have a history of making such investments.

3 After struggling with similar PHC and AET issues at our family office, I discovered taxr.ai (https://taxr.ai) and it was incredibly helpful. I uploaded our corporate documents, investment strategy, and financial statements, and their AI analyzed everything to identify our risk areas and suggest specific restructuring options. What really impressed me was how they identified that we could create a legitimate service business within our structure by formalizing the investment research and due diligence we were already doing for our own portfolio, and offering those services to a few other family offices. This created enough active business income to avoid PHC status while maintaining our core investment activities. They also helped us draft a formal capital accumulation plan that specifically documented our business needs for retained earnings, which has been critical for addressing AET concerns.

•16 How exactly does the service work? Do you just upload documents and get an automated report, or is there actual human expertise involved? I'm skeptical about trusting AI alone for something this complex.

•22 I'm curious about how this process might impact our existing estate planning structure. We have multiple trusts that own portions of our family investment corporation, and I'd be concerned about triggering unintended gift tax consequences if we restructured ownership percentages.

•3 The service combines AI analysis with human tax experts who review everything. You upload your documents, the AI does initial analysis to identify issues, and then their team of tax professionals reviews the AI findings and provides specific recommendations tailored to your situation. Regarding estate planning implications, they actually coordinate with your existing advisors. In our case, they identified potential issues with our trust ownership structure and recommended specific adjustments that preserved our estate planning goals while addressing the PHC ownership requirements. They'll flag gift tax implications of any recommended changes so you can make informed decisions.

16 Just wanted to share an update after using taxr.ai. I was initially skeptical about using an AI-based service for complex tax planning, but the results were impressive. They helped us establish a legitimate management services component within our investment company that now generates about 45% of our gross income, pushing us below the PHC threshold. What really stood out was how they analyzed our historical investment patterns and helped us create a detailed 5-year capital needs plan that specifically justified our retained earnings. They even provided templates for board resolutions and documentation that our tax attorney said significantly strengthened our position against potential AET challenges. The approach was practical rather than aggressive - focusing on legitimate business structures and proper documentation rather than exotic tax strategies. Definitely worth checking out if you're navigating these issues.

9 After multiple failed attempts to get clear guidance from the IRS on our family's PHC status (literally spent hours on hold), I used Claimyr (https://claimyr.com) and got connected to an actual IRS specialist within hours. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent walked me through the specific documentation they look for when evaluating reasonable business needs for accumulated earnings. She explained that having board minutes detailing specific investment plans with timelines, capital requirements, and business purpose is crucial. She also clarified that they look at historical investment patterns - if you've consistently made similar investments in the past, it strengthens your case for current accumulations. Was genuinely surprised at how helpful the IRS representative was once I actually got through to the right person. Saved me countless hours of research and uncertainty.

•14 Wait, so this service somehow gets you past the IRS phone tree? I've literally spent entire days trying to reach someone who could answer questions about our company's tax situation. How does it actually work?

•22 This sounds too good to be true. The IRS phone system is notoriously impossible to navigate, especially for complex business tax issues. I find it hard to believe any service could actually get you through to knowledgeable specialists.

•9 It's basically a system that navigates the IRS phone tree for you and waits on hold in your place. When an actual IRS representative answers, you get a call connecting you directly. It saved me about 3 hours of hold time. Regarding skepticism, I completely understand - I was skeptical too! But it genuinely works. The key is that they know exactly which options to select in the phone system to reach the correct department for business tax issues. The representatives I spoke with were from the Business & Specialty Tax Line, which is staffed by agents who understand these complex corporate issues.

22 I need to admit I was completely wrong about Claimyr. After seeing it mentioned here, I decided to try it despite my skepticism, and within 2 hours I was speaking with an IRS business tax specialist about our PHC concerns. The representative clarified that our family investment company's research activities could potentially qualify as active business income if properly structured and documented. She specifically mentioned that we should maintain detailed time logs of research activities, formal reports on investment analysis, and evidence that these activities directly contribute to investment decisions. She also provided specific guidance on documenting reasonable business needs for our retained earnings, including recommending we create a formal capital expenditure plan that our board reviews and updates annually. This alone was worth the time saved from sitting on hold for hours.

5 Has anyone explored using a "brother-sister" corporate structure to address these issues? We're considering creating two separate entities - one holding the passive investments and another providing legitimate business services. I'm wondering about the practical considerations of implementing this approach while maintaining family control.

•19 We actually implemented this structure last year. The key is ensuring the service business entity has genuine economic substance - real clients beyond your family, market-rate compensation, proper documentation, etc. The IRS will scrutinize transactions between related entities, so you need solid transfer pricing documentation for any inter-company services. We maintain separate boards with some overlapping and some independent directors to strengthen the case that these are truly separate businesses. The structure works well but requires significant compliance overhead.

•5 That's really helpful insight. Did you encounter any unexpected challenges with the structure? I'm particularly concerned about whether this might trigger other tax complications we haven't considered yet.

11 Our tax attorney recommended we establish a detailed shareholder agreement that requires minimum distributions of a certain percentage of earnings each year. This has helped address potential AET issues by demonstrating we're not unreasonably accumulating earnings. Has anyone else implemented something similar or found other governance approaches that help with these tax issues?

•18 We implemented a formal dividend policy that requires distributing at least 30% of annual net income unless the board specifically votes to retain additional earnings for documented business purposes. Our tax attorney suggested documenting the business justification for any retained earnings above that threshold in detailed board minutes. This approach has worked well for us because it creates a presumption that we're not hoarding cash without legitimate business needs. Our accountant said this kind of formal policy demonstrates good corporate governance and makes it easier to defend against potential AET challenges.
