When my husband has his small business our accountant told us 10 years is idea no less than 7. I would keep all of the bank statements, tax forms and ditch the rest if they are that old!
We just found three boxes of financial records for the group from 1987 - 1994. I pulled out all the IRS and state tax stuff and the treasurers reports to file. The rest is mainly bank statements and receipts. Is there any need to keep these old records?
