writer or artist or both? if both 2 schedules c's need to be filed unless your business is in the form of a corporation or partnership. expenses would then need to be allocated between the two activities. if the cost of these items is significant, they may have to be capitalized and then depreciated. they may even be regarded as start-up costs which are subject to special tax rules. weapons? real or toy? I would see an issue with deducting the cost of real weapons that can be and are intended for personal use, not as props. if their cost is significant enough they may have to be capitalized and depreciated. can't answer if the IRS would allow the cost of real weapons. also at issue is whether or not the activities would be profitable. continued losses might result in an IRS audit to see if these are for-profit activities or are hobbies in which case losses will be disallowed. also, what happens to these items when you are through with them? converting to personal use would likely require you to pick up income equal to the lower of cost or fair market value on the date of conversion.
you best advised to seek the advice of a tax pro.
