Long term capital gains are taxed at the same rate as your income (but are not added to your taxable income). You now have double the standard deduction - that means the amount you can deduct without having to itemize.
. . .
If you make less than $50k or so on your sales, the amount of capital gains tax you would pay would still be within your standard deduction.
So, I think what I'm reading, both from the two links and your response, is that even though I probably won't be taxed on what I make, I still need to report it?
Edit: I'm more confused than ever because the Wikipedia article I linked to leads to Capital Gain which leads to Capital Asset.
From the Capital Gain article I read . . .
A capital gain refers to profit that results from a sale of a capital asset, such as stock, bond or real estate, where the sale price exceeds the purchase price. The gain is the difference between a higher selling price and a lower purchase price.
and from Capital Asset I read . . .
Excluded from the definition of capital assets
Any movable property (excluding jewellery made out of gold, silver, precious stones, and drawing, paintings, sculptures, archeological collections, Dinosaur bones, etc.) used for personal use by the assessee or any member (dependent) of assessee’s family is not treated as capital assets. For example, wearing apparel, furniture, car or scooter, TV, refrigerator, musical instruments, gun, revolver, generator, etc. is the examples of personal effects. (But see IRS publication 544 chapter 2.)
To cut to the chase, I'm selling pretty much all of my old electronics and my comics, but I doubt I'd be making much of a profit (if any) off of them and I doubt they'd be considered a capital asset.
I feel dumb and lost here.
