Thanks for sharing your experience! What exactly is an Acceptance Agent and how do I find one in Warsaw? Also, did ETH Denver (or equivalent in your case) actually agree to the extension when you asked?

An Acceptance Agent is someone authorized by the IRS to verify identification documents for ITIN applications. They can certify your original documents so you don't have to mail them to the IRS. You can find a list of international agents on the IRS website - search for "acceptance agents abroad" and filter for Poland. The tech competition in my case did agree to a 45-day extension. They were understanding once I showed them documentation that I had started the TIN application process. I found that being transparent about the timeline and keeping them updated regularly made them more willing to work with me. I sent them the receipt from the Acceptance Agent as proof that I had actually started the process, which helped a lot.

That's not correct advice at all. State ID numbers are completely different from federal taxpayer identification numbers and aren't recognized for federal tax treaty purposes. Either your cousin misunderstood what happened or the organizers made a mistake. Using a state ID in place of a TIN on W-8BEN could actually create bigger problems down the road when the IRS reviews the withholding.

I did think about the standard mileage deduction, but from what I've calculated, the actual expense method will probably be more beneficial in my case. I drive the EV almost exclusively for business, and with the depreciation of the vehicle plus all the other expenses, I think I'll come out ahead with actual expenses. But you're right that standard mileage would definitely simplify things!

The standard mileage rate doesn't actually work well for EVs in many cases. It was designed around gas vehicles and their maintenance costs. EVs have higher upfront costs but lower per-mile costs, so you might be leaving money on the table using standard mileage.

What documentation did you need to prove the business use percentage? I'm getting a charger installed next month and want to make sure I have everything ready for tax time.

I use the simplified method for my Etsy shop and it's so much easier than tracking all those expenses. But remember you still need a space that's EXCLUSIVELY for business use. I converted a small closet (about one-sixth of my apartment's square footage) to store inventory and take product photos, and I only claim that area.

Thank you so much for breaking it down like this!! This makes perfect sense now. I was getting so confused because our accountant kept saying "inheritance isn't taxable" (which seems correct) but wasn't addressing the actual problem of how to deposit the check. I just got the EIN online following your steps and have an appointment with the bank tomorrow to open the estate account. Will the final 1041 be complicated to file? Or is it pretty straightforward since there's no tax due?

The 1041 for this situation is very straightforward. Since there's no income being generated by the estate (just passing through the inheritance), it's basically just identifying information and zeros for the income portions. Many people do it themselves for simple cases like yours. The form asks for the EIN, estate name, when it was opened/closed, beneficiaries, and income details. Since inheritance isn't income, you'll show the money coming in and going out to the heir(s) with no taxable amount. It's mainly filing it to show the IRS that the estate was opened and closed properly. Your accountant can do this very simply, or there are templates online if you want to DIY.

I used TurboTax Business for my mother's estate last year. It worked fine for a simple estate situation. The software walks you through all the questions and it's pretty straightforward if you're just dealing with passing inheritance through. Make sure you get the Business version though, the regular TurboTax doesn't do 1041s.

This is why I always take the extra step to get a win/loss statement from gambling sites that offer them. Does your crypto gambling site provide any kind of statement or summary you can download for tax purposes?

Most legit crypto gambling sites do offer some form of win/loss statement or transaction history you can download. It's not always as detailed as traditional casinos, but it's better than nothing. For sites that don't provide good documentation, I've started keeping a spreadsheet with dates, amounts, screenshots of balances before and after significant wins/losses, and the withdrawal transactions. The more documentation you have linking the gambling activity to the crypto you received, the easier it is if questions come up later.

Thanks for breaking it down like this! The gift card to gambling site to ETH withdrawal path had me so confused. And yes, it was about $1000 worth when I cashed out, so the 10.1% decrease tracks with the market dip after I withdrew. I'm going to double check the exact date and ETH price to make sure my software has it right.
