There is a lot of bad information in this thread.
The best answer is this: the band leader should talk to a tax professional, and get competent, accurate tax advice.
If he declared the income on a Schedule C, then he should have been able to deduct the amounts he paid to the other members of the band as an expense. If he did not do this, it may be possible for him to amend his return to do this, depending on when it was filed. Again, he should seek the advice of a tax professional.
That's the best advice.... seeing a tax professional. HOWEVER: it is not legal for him to pay taxes on what he was 1099'd for and you guys pay him back what he paid in taxes. And he needs to 1099 them, not claim them as expenses.
You don't need to do an LLC, band leader needs to 1099 all the people he paid the money to.
You all need to file schedule C's, deduct the equipment bought (you have receipts, right?) If you made money, pay your tax. If you lost money, you don't pay taxes.
Now, if you lost money because you spent more on equipment than you made, you can deduct those losses, and essentially the band is more like a tax shelter than additional income, it cost you money. It'll reduce the taxes owed from your day job. Its a business that lost money. Losses are deductable.
HOWEVER! You have to make money with the band at some point. Otherwise, its no longer a business, its a hobby. With a hobby, you can offset your earnings with expenses, but if you lose money, you can NOT deduct those losses that are more than your earnings against to reduce taxes paid on your day job. You can ONLY offset your band earnings with band expenses if its a hobby.
If it ends up as a hobby a few years from now, you'd have to go back and amend tax returns where you lost money. You can only end up at 0 with a hobby, if you spent thousands on equipment and made hundreds, tough. Once you get to 0 income, the rest of the expenses beyond your band earnings can't be deducted.
Day job: 25,000
Band : 5,000
Band expenses: 10,000
BUSINESS:
If you make money often enough, its a business. Meaning make more money than you spend. This year you lost money though.
25,000 + 5,000 - 10,000 = pay taxes on 20,000. You just saved money on taxes paid on your day job because your other business (band) lost money.
HOBBY:
If you lose money too many years in a row, its a hobby, not a business. Losses from the band only offset earnings from the band, losses beyond that can not be applied to your total income. Its no longer a tax shelter.
25,000 + 5,000 - 5,000 (-5000) = pay taxes on 25,000. The 2nd -5,000 in expenses are not deductible since band is a hobby. Now you have to go back and fix prior year returns where you claimed the extra 5,000 expenses as a deduction in prior year returns when you thought it was a business. Its not a business, and becomes a hobby,
retroactively.
In a nutshell, that's my understanding. I'm not a tax attorney, so take my advice with a grain of salt and see a tax professional. Turbo Tax is great, but first time through you probably need to hire a pro and understand the process. After that, maybe going forward Turbo Tax will be fine.
