Starting Your Business/Keeping Tax Records 
              Recordkeeping
              
              Except in a few cases, the law does not require any special kind 
                of records. You may choose any recordkeeping system suited to 
                your business that clearly shows your income.
              The business you are in affects the type of records you need 
                to keep for federal tax purposes. You should set up your recordkeeping 
                system using an accounting method that clearly shows your income 
                for your tax year. See  
                Accounting Method . If you are in more than one business, 
                you should keep a complete and separate set of records for each 
                business.
              Your recordkeeping system should include a summary of your business 
                transactions. This summary is ordinarily made in your books (for 
                example, accounting journals and ledgers). Your books must show 
                your gross income, as well as your deductions and credits. For 
                most small businesses, the 
                business checkbook is the main source for entries in the business 
                books. In addition, you must keep supporting documents.

              In addition, The Occupational Safety and Health Administration 
                requires that you keep records of work-related illnesses and injuries.
