The main question would be - if the business already started and your expenses are operational expenses or the business has not started yet - and your expenses are start-up expenses?
It is not clear from your explanation, but because you never made a penny - I tend to think that your business is not started.
Start-up cost is considered your investment and treated differently. Start-up cost - expenses you had before the business started - in general should be amortized over 15 years.
If you haven't started the business yet - you may not deduct any start-up cost.
You can write off up to $5,000 in startup costs and another $5,000 in organizational expenses in the year that you start your business. However if you have losses you may not deduct start-up cost.
If you can't deduct start-up cost in the first year - you should amortize these expenses over 15 years - thus in the first year you will deduct 1/15 part of the total expenses - and so on in following years.
If you sell the business before deducting all of the start-up costs, you may deduct the remaining start-up costs as a loss as allowed by Sections 165 and 195(b)(2).
You may deduct start-up cost only after the business is started.
LLC is not taxable entity and as one-member LLC - it is taxed as a self-proprietorship.
If your business is started - you may deduct 1/15 of start up cost every year. You would need to file a schedule C - http://www.irs.gov/pub/irs-pdf/f1040sc.pdf to report gain/loss from the business.
