As the others have stated, your statement is vague as to the type of expenses and the reasons why they were disallowed.
Was this a correspondence audit? Face to face audit?
Why were the expenses disallowed....should have been capitalized and amortized? Lack of substantiation (receipts, records, etc.)? Expenses more personal in nature than business?
Whether it was a correspondence audit or face to face (but especially face to face), there should have been reasons/explanations given for each category of expense(s) that was disallowed. When I was auditing for IRS, that was a specific requirement that I had to do; and I did so in detail.
For the people in this forum to give advice, there needs to be more details.
