If you're making a profiut from free lancing - even if it is just a few thousand dollars, it is to your advantage to take advantage of every tax break you can, and if you nare just throwing up your hands and saying, "It's too complicated for me to keep track of," I guarantee you that the money you spend on an accountant will be offset by your tax savings. Otherwise you are giving away money - you have to declare the income, you you may as well declare every legal expense.
Example, say you make $2000 a year freelancing, either by itself or in addition to a day job, in or out of the business. If you have a dedicated office, you can deduct that percentage of your housing expenses, including utilities.. use of cell phone? Deductable. Magazine and newspaper subscriptions? Deductable. Books purchased., postage, copies, that new laptop? Ditto. In fact, you may even have more deductions than income - that's okay, you are then tax free... You just have to show profit one of every four years.
This is generally where someone jumps in and says "You'll get audited!!!" Don't lie, and just be squeaky clean.
