That's a great point! I completely forgot about my charitable donations last year. I gave about $2,200 to various organizations and I have all the receipts. Would that be worth including in my amendment too? Also, do I need to send in copies of my mortgage interest statement and donation receipts with the amendment?

Absolutely include those charitable donations in your amendment! $2,200 is definitely significant and will increase your refund further. Combined with your mortgage interest, you're well over the standard deduction threshold. You don't necessarily need to send in the documentation with your amendment, but you should absolutely keep all those receipts, donation acknowledgments, and your Form 1098 mortgage interest statement with your tax records. The IRS can request substantiation later, especially for amended returns which tend to be reviewed more carefully.

Yes, you actually can e-file Form 1040-X now! The IRS started allowing this in 2020. Most major tax software (TurboTax, H&R Block, TaxAct, etc.) supports e-filing amendments. It's wayyy faster than paper filing and you get confirmation that they received it.

Thanks for sharing this - makes me feel a bit better. Did you have to pay a lot in penalties when you amended for those stock gains? And how long did the whole amendment process take?

The penalty wasn't bad at all - I think it ended up being around $80 plus some interest on the unpaid tax. So all in maybe $120 extra beyond what I would have paid originally. The amendment took about 3-4 months to process completely, which I hear is actually pretty fast for the IRS these days. Just make sure you keep copies of absolutely everything you submit and proof that you sent it (certified mail is good).

This isn't always true - I tried to amend through TurboTax and they wanted to charge me for the "deluxe" version even though my original filing was free. Ended up having to pay like $60.

Thank you for mentioning this! I just checked the 1099-MISC more carefully and they actually did withhold some tax (about $405). So when I file the 1040-NR with Schedule NEC, do I just list that amount as already paid? Is there a specific line for this on the form?

Yes, you'll report the income on Schedule NEC, and then on Form 1040-NR, there's a line for "Federal income tax withheld" (typically line 25c or similar depending on the tax year). This is where you'll enter the $405 that was withheld. This is actually good news for two reasons: First, it shows the company properly classified you as a foreign person. Second, if you qualify for a lower tax rate under a treaty, you might get some of that withholding refunded back to you. Make sure you attach a copy of your 1099-MISC showing the withholding when you file your return. And remember that you'll likely need Form 8833 to claim any treaty benefits if you're eligible for a rate lower than 30%.

I tried TurboTax for my 1040-NR last year and it was a disaster. They don't really support all the international forms properly. I ended up using Sprintax which is specifically designed for nonresident returns. It handled Schedule NEC and treaty claims much better.

Would this approach work in TurboTax too? I'm having almost the identical issue but with TT and a car my grandpa gave me that I donated to a local charity.

Yes, the approach works in TurboTax too. The key is the sequence of entering information. TurboTax tends to make assumptions if you immediately identify something as a gift. Enter the donation details first, then go back to modify the acquisition information. For TurboTax specifically, after entering the 1098-C information, look for the "Asset Information" section where you can edit the basis details. Enter what your grandfather originally paid for the car (estimate if needed) and when he purchased it originally. This establishes a proper basis instead of the $0 that TurboTax might default to.

That's not quite right. The basis absolutely matters with donated property, even vehicles. The deduction is limited to the LESSER of your basis or the gross proceeds reported on the 1098-C. So if your basis is $0 (which can happen with fully depreciated gifted property), your deduction would also be $0, even if the charity sold it for more.

I stand corrected! You're right about the "lesser of" rule. I checked Publication 526 and it does specify that for vehicle donations, your deduction is limited to the smaller of your basis or the gross proceeds from the charity's sale. This explains why the software is asking about the gift - it's trying to determine the basis. If the original owner had already fully depreciated the car (common for older vehicles), then the basis might indeed be $0, which would limit the deduction to $0 regardless of sale proceeds.

H&R Block's truly free version doesn't support Schedule C or self-employment income. You'd need their Self-Employed version which runs about $85 for federal filing plus another $37 per state. I switched from them to FreeTaxUSA last year and saved a ton of money. H&R Block isn't terrible, but they're almost as expensive as TurboTax for self-employment stuff.

Thanks for the info! That's disappointing but good to know before I waste time starting with them. Seems like FreeTaxUSA is the winner for most people in this thread.

I've thought about going the direct form route, but I'm a bit intimidated by figuring out depreciation schedules on my own. Did you find good resources for learning how to do that part correctly? I'm comfortable with the general Schedule C stuff but some of the more technical aspects make me nervous about doing it without software guidance.

I found Publication 946 from the IRS really helpful - it explains all the depreciation rules. There are also some free online depreciation calculators that can help you determine the right amounts. I created a spreadsheet that I update each year for tracking my business assets and depreciation. The first year was definitely the hardest, but now I just update my spreadsheet annually. I actually feel more confident now because I understand exactly what's happening rather than trusting software to make the right choices for me. If you're comfortable with spreadsheets, it's totally doable with a bit of research.
