If they are going to 1099 you, make sure that you keep track of your expenses (mileage and so forth). When you do your taxes (I always use a tax person, just for this very reason), I take the 1099 in with the rest of my paperwork, and my records of expenses.
Additionally, if you're working as a consultant, you may be able to write off other business expenses, such as:
* a percentage of your house payment, utilities, and so forth, if you have established an office area in your home.
* a second phone line
* internet service fees (if it's used in your business; mine is)
A 1099 is essentially a statement of earnings; they will *not* be taking taxes out. You will need to pay those; that's why you need to keep track of expenses as well.
Keep in mind that when you are negotiating your fees for consulting, the following:
1) They're not taking out taxes, you will be responsible for those. Adjust your rates accordingly.
2) They're also not paying for your insurance, worker's comp, etc. etc.
3) They're not "required" to keep you. If they don't like you for some reason, or you tick someone off, you have no grievance process, etc. They are now your customer, and they have the right to take their business elsewhere.
I consult for a few businesses. They 1099 me every year. But, I have enough expenses that I can write off (in addition to claiming "0" on my regular job so they withhold as much as possible) that I don't get stuck paying taxes at the end of the year.
Take your taxes to a tax person. When you start dealing with 1099's and other things, it's well worth the $125 to go to H&R Block. They know what you can write off, what you can't, what percentage, etc.
Just my 2¢
