You should get a Tax Identification Number (TIN)from the IRS. This is easily done online. You should report your income and expenses on Schedule C (Income from Business or Profession) which is attached to your 1040. You will also have to file an attachment for computing your Self-Employment Tax (Social Security). If you wish to file quarterly payments during your first year (1040-ES), it might be a good idea.to look at the IRS Guide for Small Businesses. You do not need a special checking account, but you must keep very clear records. A program like Quickbooks is good for this. Good luck. .
