You need to report all earnings.
This has nothing to do with what you made.
It was about you having to send 1099's to any company you spent over $600 with.
So if you bought a $1000 lens from Adorama you would need to send them a 1099.
And if you bought a Computer from Apple you would need to send them a 1099.
It was going to be a nightmare - thank goodness they are dumping this provision.
(edit) this wasn't to take effect this year anyways)
Well, you would have had to file a 1099 if you had bought that lens with cash or check. Apparently, "electronic transactions" like credit and debit cards were exempt from the 1099 filing.
Which makes me ask who pays cash anymore for things like this? Oh I just mailed $1000 cash to B&H for a lens and camera bag. (not really but you get the idea) Or who mails checks for payments anymore, same type of purchase. Sure some people do, but we all have debit cards direct from checking or savings, or charge cards which we can transfer funds electronically to pay from our bank account, no interest. Who needs to make cash transactions?
And may I concur, it was a stupid law to start with!
This one is still around:
What payments must be reported?
A business must file Form 8300 to report cash paid to it if the cash payment is:
Over $10,000,
Received as:
1. One lump sum of over $10,000,
2. Two or more related payments that total in excess of $10,000, or
3. Payments received as part of a single transaction (or two or more related transactions) that cause the total cash received within a 12-month period to total more than $10,000.
Received in the course of trade or business,
Received from the same buyer (or agent), and
Received in a single transaction or in two or more related transactions.
And this one, just for those who are amused
Report gambling winnings on Form W-2G if:
1. The winnings (not reduced by the wager) are $1,200 or more from a bingo game or slot machine,
2. The winnings (reduced by the wager) are $1,500 or more from a keno game,
3. The winnings (reduced by the wager or buy-in) are more than $5,000 from a poker tournament,
4. The winnings (except winnings from bingo, slot machines, keno, and poker tournaments) reduced, at the option of the payer, by the wager are:
1. $600 or more, and
2. At least 300 times the amount of the wager, or
5. The winnings are subject to federal income tax withholding (either regular gambling withholding or backup withholding).
So you see a slot machine and notice the top payout line is $1,199
Or a payout on a Keno ticket is $1499
Reduction in paperwork for casinos. Now you know why.

I'm still pissed off that some stupid club mailed me (and the IRS) a 1099 because they paid me exactly $600 last year. I said, please pay me $599 and send me a patch or sell me a club T-shirt and send me less, but don't pay me $600! The lady said, Oh no problem. January last year I got the 1099 in the mail. Yeah, well start figuring taxes, and that $600 became $450 in a blink.(maybe worse) and at $100 a day, I worked a day and a half for free because they couldn't just pay me $99 a day? Stupid!
