Has anyone dealt with the practical aspects of getting ITINs for foreign members? I've found that to be one of the most time-consuming parts of the process.

One thing I haven't seen mentioned yet is the potential impact of tax treaties between the US and the foreign corporation's country of residence. If there's a favorable tax treaty in place, it could significantly reduce the branch profits tax rate or potentially eliminate it altogether. The standard branch profits tax is 30%, but many treaties reduce this to 5% or even 0% in some cases. Also, consider the timing of your ownership change carefully. If you make the switch mid-year, you'll need to file both a short-year partnership return (Form 1065) for the period with multiple members AND treat the remainder of the year as a disregarded entity/branch operation. This creates additional complexity and potential for errors. I'd strongly recommend consulting with a tax professional who specializes in international business structures before making this change. The compliance burden and potential penalties for getting foreign-owned entity reporting wrong can be substantial.

One thing I haven't seen mentioned is how the tax treaties between the US and Canada might impact your situation. As a Canadian citizen who's a US tax resident, you might be eligible for certain protections under the US-Canada tax treaty. However, tax treaties generally don't help much with offshore structures in places like the Cayman Islands. In fact, these structures often trigger anti-avoidance provisions in tax laws. My biggest concern would be that this arrangement could potentially be viewed as a tax avoidance scheme by the IRS, especially given the lack of substantial business operations in the offshore jurisdiction. The IRS has become extremely aggressive in pursuing offshore accounts in recent years.

I want to emphasize something that hasn't been fully addressed - the potential criminal penalties for willful failure to report foreign accounts. As someone who went through an offshore voluntary disclosure program, I can tell you the stakes are much higher than just paying additional taxes. The willful failure to file FBAR can result in penalties of up to 50% of the account balance PER YEAR, and in extreme cases, criminal prosecution. Given that you're talking about potentially substantial trading profits, these penalties could be devastating. Also, consider that the IRS has extensive data sharing agreements with financial institutions worldwide. Interactive Brokers, for example, reports account information to the IRS under FATCA requirements, regardless of where your account is domiciled. The idea that offshore accounts provide privacy from the US tax authorities is largely a myth in 2025. My strong recommendation would be to consult with both a US tax attorney specializing in international taxation AND a Canadian tax professional familiar with US treaty provisions before moving forward. The cost of proper planning upfront is minimal compared to the potential penalties and legal fees if this goes wrong.

Great thread! I'm also considering making the switch from H&R Block. Reading everyone's experiences really highlights how much value a good EA can provide beyond just filling out forms. One thing I'm curious about - for those who switched, how did you find your EA? Did you go through the IRS directory, get referrals, or use another method? I want to make sure I find someone with experience in small business situations like mine (freelance graphic design work plus rental property). Also, when you first met with your EA, what questions did you ask to evaluate whether they were a good fit? I don't want to make the same mistake of ending up with someone who just goes through the motions, even if they have better credentials than H&R Block preparers.

I made the switch from H&R Block to an EA last year and it was absolutely worth it. My situation was similar - W-2 income plus a growing freelance business and some investment income. At H&R Block, I felt like I was getting cookie-cutter service for $340, and when I asked about business deductions, the preparer seemed unsure and kept looking things up. My EA charges $525, but in the first year alone they found $2,900 in deductions H&R Block had missed - proper business use of vehicle calculations, home office deductions I qualified for, and equipment depreciation I never knew about. They also helped me set up a SEP-IRA which saves me thousands annually. The biggest difference is the ongoing relationship. My EA proactively reaches out with tax planning suggestions throughout the year. Last fall, they recommended some equipment purchases and retirement contributions that significantly reduced my tax burden. With H&R Block, it was always just a once-a-year transaction. One tip: interview a few EAs before choosing. Ask about their experience with your specific situation and whether year-round consultations are included or extra. The good ones will ask detailed questions about your business and suggest strategies right in the initial meeting.

Just wanted to add that I tried a similar strategy a few years ago with a BVI corporation for my trading activity. Ended up paying over $45,000 in penalties and back taxes when I got flagged for audit. The IRS agent told me they specifically look for US traders trying to route activities through Caribbean tax havens.

I've been researching similar offshore strategies for my trading business and I have to echo what others have said - the risks far outweigh any potential benefits. The IRS has really cracked down on these structures over the past decade. What changed my perspective was learning about the "economic substance doctrine" - even if you technically follow all the rules for setting up an offshore entity, the IRS can still challenge it if there's no legitimate business purpose beyond tax avoidance. For day trading, it's really hard to establish genuine economic substance in the Cayman Islands when you're sitting at your computer in the US making all the trades. I ended up working with a tax professional who specialized in trader tax status and found legitimate domestic strategies that actually reduced my tax burden more than I expected. Things like proper entity selection, maximizing business expense deductions, and qualifying for trader tax status can make a significant difference without the compliance nightmare and legal risks of offshore structures. The reporting requirements alone for foreign entities would probably cost you more in professional fees than you'd save in taxes, not to mention the constant worry about whether you're crossing the line into evasion territory.

Just wondering - does having a SSN from your internships change anything about how you fill out the W8-BEN? I got a social when I worked in the US last summer.

Just to add one more perspective here - don't stress too much about the W8-BEN form. It's actually pretty straightforward once you understand what it's for. The key thing to remember is that this form is specifically about the interest income your bank account generates, not your employment income. Since you're Canadian, you'll definitely benefit from the tax treaty. The US-Canada treaty eliminates withholding on bank interest entirely (0% instead of 30%), so filling out this form will actually save you money on any interest you earn. One thing I'd suggest is to keep a copy of your completed W8-BEN for your records. When you do eventually become a US tax resident (which sounds like it'll happen soon with your full-time move), you'll need to notify your bank and switch to providing them with a W-9 form instead. Having documentation of when you made that transition can be helpful for tax purposes. The form itself is valid for 3 years, but your circumstances are changing, so you'll likely need to update it sooner than that. Good luck with your move!
