Yes. If you were paid in Bitcoin or another cryptocurrency, you should report your earnings as income (like you would if you had been paid in cash). You'll also report any new cryptocurrency you received from a hard fork followed by an airdrop or other transfer as ordinary income.
If you hold Bitcoins or other cryptocurrencies as a capital asset, you must treat them as property for tax purposes. If you sold them for profit, you must report earnings regardless of whether or not you received a tax form.
Keep in mind: If you've already filed a return and didn't report your cryptocurrency earnings, you'll need to amend it.
