eBay 1099-K Form and Collectible Classification

Megan

Hi everyone, I have a few questions regarding the 1099-K form I received from eBay. This is my first time having to file anything besides a W2 and I'm having some difficulty. I used to collect anime figures/dolls in my 20s but have since outgrown it and am trying to offload most of my collection. I sold from February 2025 to December 2025, totaling 82 transactions. Some were at a (relatively small, $5-$100 at most) gain, and others at a loss. My questions are as follows:

1. Do I have to list each sale at a gain individually, and provide the exact amount profited? And this should be done in the "Your Investment and Savings Accounts", right?
2. I no longer have the transaction records of some older items. Some are from 10 years ago. Is my best guess for when I bought it/how much I paid okay?
3. Do anime figures/dolls count as collectibles, and should I be qualifying them as such?
4. Under Sale Proceeds, it asks me to use the information in Box 1a, but that's the total for the whole year, which includes sales that were both gains and losses. Should I instead use the monthly breakdown boxes (5a-5l)? If so, where should I be entering the information from Box 1a?
5. ETA one more question related to the above: I sold one thing in February for a $190 listing price that I paid $120 for. However, after eBay fees, I was paid only $160. Box 5b shows $190. Even though I didn't make $70 in profit, am I still entering the amount the buyer paid and not what I received?

I ordered these items across different websites and vendors and I'm finding it very tedious to track down every single one, see what I paid, then subtract that from what I sold it for, especially when it only ends up being an amount in the single digits. I'm trying to do everything right but if there's an easier way to get through this for 82 transactions I would love the help. I understand this is my fault for not keeping good records, I've definitely learned my lesson for next year lol. Thank you so much for reading all of this!

Hi,

Thank you for reaching out — these are great questions and you're clearly trying to do this right.

1. Yes, each sale at a gain needs to be entered individually. In the software, go to Income > Common Income > Investments and Savings > Add Another Investment > Personal Items (1099-K). You'll enter the sale proceeds and cost basis for each profitable transaction there. The good news: you only have to do this for the items where you made money. Items sold at a loss are handled differently (see below).

2. A reasonable good-faith estimate for your cost basis is generally acceptable when you don't have the original receipt. Try to document how you arrived at the number — for example, searching completed eBay listings from around the time you bought it, or noting the typical retail price at the time. The IRS generally accepts honest estimates as long as you can explain your method.

3. You don't use Box 1a as a single lump-sum entry for your gains. Instead, you enter each gain transaction individually with its own sale proceeds and cost basis. Box 1a is just the total gross amount eBay reported — it's a reference point, not a single entry field. For your loss transactions, you'll enter the total amount received from those sales as a single number. Go to Income > Business Income > 1099-K Income, answer "Yes" to personal transactions, and "Yes" to items sold at a loss, then enter the combined total proceeds from all your loss sales. This zeros them out so you don't pay tax on them.

5. For the February example: you enter $190 as the sale proceeds (the gross amount the buyer paid, which is what Box 5b shows). However, you can add the eBay fees to your cost basis. So instead of entering $120 as your basis, you'd enter $120 + $30 in fees = $150. That gives you a taxable gain of $40 ($190 - $150) rather than $70, which is the correct taxable amount.

6. The good news here is that you only need to enter the gain transactions individually — not all 82. If you can separate your 82 sales into "sold at a gain" and "sold at a loss," the loss group gets entered as one combined total. Only the gain transactions need to be listed one by one. That should cut down your work significantly.
