If you operate a business (have a FEIN) and the equipment you purchased is directly related to your business class then you can deduct them as operating expenses...
Do you recommend I register as a business then?
Here is my scenario example:
Bill has 2 computers which he bought for $2,000 each for a total of $4,000.
Bill was able to mine 20 Bitcoins from January 2013 to December 2013.
Bill did NOT sell any of his bitcoins and did not purchase any items with his bitcoins.
Bill also has a full time job and does mining as a hobby.
What is Bill's best approach in reporting his hobby/business with the IRS that will benefit both Bill and the IRS while completely complying with the IRS.
Bill does not want to get in trouble with the IRS
I'm no CPA but I've operated a business for several years and handled my own taxes. Don't take this as legal advice.
If you want to claim a deduction on the $4,000 dollars you will need to pay for a business license and get yourself a FEIN. Otherwise your expenses won't qualify as "business expenses." You would look at it like a business which operates under a loss until you make a transaction with your Bitcoins. Keep in mind if you spend them on more Bitcoin mining equipment this is deductible.
Your bitcoins will be viewed as an inventory item and the cost of electricity is the cost of your inventory. Once you sell them or buy something with them (barter) you will need to record it and pay taxes accordingly. If you operate at a loss or break-even you probably won't owe taxes at all and if you make a profit you can claim the applicable deductions to where you may owe no taxes or at least reduce your tax liability.
It's not uncommon for a business owner to pay themselves as a W2 employee. It's actually less of a headache in my opinion. I put myself on regular payroll with ADP and let them take care of everything. (Of course, it doesn't matter who is paying you as long as it's recorded accordingly.)
You will have no trouble with the IRS if you treat it this way unless they come right out and set a public policy. This is the closest real world analogy I can see for tax purposes.
The only way I would say "go ahead and register a business" would be if you plan to deduct your hardware expenses and electricity from other taxable income directly related to your mining.
You can only reduce your personal income tax liability for certain business related expenses like (gas, lodging, basically anything required as part of your business.) I don't think you will be able to reduce your personal tax liability by operating a "bitcoin mining business" because I believe they will be filed as separate returns if you are a W2 employee with another company.
I always filed separately at least...
