Deductions & credits

i wouldn't worry.  the IRS only audits about 1% of the returns and concentrates on those with the highest income because that's where the biggest adjustments come. there is no way to absolutely prevent an audit since some returns are selected at random.   some advice. have a separate bank a/c for your business.  deposit all receipts and pay all bills using this a/c. then you can make transfers to your personal account to pay personal bills.
