Has anyone used the "safe harbor" for small taxpayers to simplify all this? I think if your business is below certain revenue thresholds, you can just expense repairs and improvements under $2,500 per invoice immediately instead of depreciating. My CPA used this for my yoga studio buildout last year and it saved me tons of headaches with categorization.

Just wanted to add my experience as someone who went through this exact situation with my martial arts studio last year. One thing that really helped me was keeping detailed records not just of what I bought, but WHY each expense was necessary for the business operation. For example, I documented that the specialized flooring wasn't just "nice to have" but was required for safety and insurance purposes. This helped justify immediate expensing under Section 179 for some items that might otherwise have been depreciated. Also, don't forget about the Qualified Improvement Property rules that changed recently. Some buildout expenses that used to be depreciated over 39 years can now be depreciated over 15 years, which is a huge improvement. If you're feeling overwhelmed, consider at least getting a one-hour consultation with a CPA who specializes in small business. The money you spend on that consultation will likely save you much more in proper deductions and avoiding costly mistakes. I wish I had done that from the start instead of trying to figure everything out myself.

The IRS is so inconsistent with this stuff. My friend and I both filed amended returns around the same time last year, both for W2 corrections. She got a direct deposit and I got a stupid paper check that took like 2 additional weeks to arrive. When I called to ask why, the agent just said "that's how the system processed it" 🙄 There's no rhyme or reason sometimes.

I just went through this exact situation! Got my 846 code last week for an amended return and was stressing about the same thing. Ended up calling the IRS using one of those callback services mentioned here and the agent told me that while most amended refunds do come as paper checks, there's actually no way to know for certain until it's processed completely. She said to check my bank account for 3-5 business days after the 846 date, and if nothing shows up, then expect a paper check in 2-3 weeks. I'm still in the waiting phase but at least I have a timeline now. The uncertainty is the worst part of this whole process!

Another thing to consider with RSUs - if you hold the shares after vesting and sell within a year, any gain/loss is short-term capital gain/loss. If you hold more than a year after vesting, then it becomes long-term capital gain/loss. This matters because short-term capital gains are taxed at your ordinary income rate, while long-term capital gains get the preferential tax rates (0%, 15%, or 20% depending on your income level). So while your capital loss carryover can offset either type of gain, it might be strategically better to use it against short-term gains if you have both.

This is a really comprehensive discussion! I wanted to add one more consideration that might be helpful for OP and others - timing your RSU sales strategically with your capital loss carryover. Since you have $55k in capital loss carryover, you might want to consider holding onto those RSU shares after they vest and selling them strategically over multiple years. Here's why: if the shares appreciate and you sell them all at once for a big gain, you'll use up your entire loss carryover in one year. But if you spread the sales over several years, you can also take advantage of the $3k annual deduction against ordinary income each year. For example, if you sell $10k worth of gains each year, you'd offset that with your carryover losses AND still get to deduct $3k against your regular income each year. This way you're maximizing the tax benefit of those losses. Of course, this assumes you're comfortable with the investment risk of holding the shares longer. Just something to consider when planning your RSU strategy!

Has anyone considered using a LLC taxed as an S-corp instead? That might give you some of the liability protection without the double taxation of a C-corp. Been thinking about this for my own investments.

Just wanted to add my perspective as someone who went through this exact decision last year. I had about $280k in dividend stocks generating around $9k annually and spent months researching whether to incorporate. After consulting with a CPA and running the numbers multiple ways, I stuck with direct ownership. The math just didn't work out for a passive investment portfolio - the double taxation issue everyone mentioned is real, and the administrative costs (filing corporate returns, maintaining corporate records, etc.) would have eaten into any potential benefits. One thing I learned that might help: if your main goal is reducing the tax burden on dividends, focus on tax-loss harvesting and holding qualified dividend stocks for the lower tax rates instead of changing your ownership structure. For most people with portfolios under $500k that are primarily passive investments, the complexity of corporate structures just isn't worth it. The only scenario where I'd reconsider is if I was actively managing investments as a business (like day trading or running a fund), but for buy-and-hold dividend investing, keep it simple!

Has anyone had issues with US clients still withholding taxes even after submitting a properly filled W8-BEN? I'm from Portugal (similar tax treaty to Spain) and one client still withheld 10% despite the form. Is there a way to get that money back?

As someone who's been helping international freelancers with US tax compliance for years, I want to emphasize a few key points that haven't been fully covered: First, make absolutely sure you're eligible to claim treaty benefits. You must be a Spanish tax resident (not just a citizen) and the beneficial owner of the income. If you're a digital nomad who spends significant time outside Spain, this could affect your eligibility. Second, regarding the NIE format in section 5 - it should include the full number with letters (like X1234567L), not just the numeric portion. I've seen many forms rejected for this simple formatting error. Third, while Article 14 is correct for most freelance work, be aware that if your services could be considered "royalties" (like licensing creative work) or if you have employees/subcontractors in the US, different treaty provisions might apply. Finally, keep detailed records of when you submit the W8-BEN to each client. Some companies have poor internal processes and may "lose" your form, leading to unexpected withholding months later. Having proof of submission helps resolve these issues quickly. The Spain-US treaty is generally very favorable for freelancers, but proper documentation is crucial for avoiding headaches down the road.
