you dont need a B-License to write off business equipment and expenses for the federal Government. Just use your Schd. C. Use depreciation for Camera Gear and Computers (unless they are "replacement" but there is an associated denial risk and penalties with interest risk with that approach), also uses the various expenses for your various expenses (milage, meals, supplies . . .). Remember dont take computers as 3 year depreciation, 5 or more. IRS says five so thats what you have to use.
It would be wise to pull all of your capital purchase receipts and make a spread sheet of cost, serial numbers, place of purchase, invoice number, repairs . . ., everything. You can then figure out your depreciation and maintiance cost via these sheets and really show expenses and depreciation. Remember you can have book and tax depreciation too. Work as much stuff to your advantage as you can. Try and get enough this year, but remember to plan your taxes well too. A 100 savings this year, might mean you owe 100 in the next 4 or 5, so becareful and dont corner yourself in future periods. If you have never done your taxes dont start now. Take them to the tax man. They can help guide you.
To get my taxes done was 97.00. I ended up with 0 Adjuested Gross Income and am getting a hefty reutrn (~2500). I get to look forward to deducting 906 dollars off my AGI for the next 6 years, plus what ever i add this year and subsequent years. This was also my first "official" year in "business", but i actaully wont start making any sort of profit until late this year or next year.
The absolute most important thing is keep spectacular records. Log everything. Hours shooting, touching photos, trying to sell, trying to print, building websites. Act as a business in a business manor and you can possibly skirt the make money in 3 of the first 5 rule the IRS has if you can demonstrate a business like setting. (seek advice from a CPA before trying this).
Edit: i just re-read the first post. Make sure you know how your being paid. Depending on the payment details you may need to adjust how you claim. If they do not take taxes out right away, you may need to send payment into the IRS. There is a penalty (i believe, meaning its been two years since my tax class in this is a little fuzzy) if you owe more then 10% of your bill at the end of the year. But check with an Accountant on that one. I cant remember the rules and im really being lazy by not checkin the IRS.gov website.
