Step 1
Verify that the IRS notice is accurate. You may have reported the item or items in a manner which is not obvious on the tax return such as netting income against expenses.
-
Step 2
Review how the IRS adjusted the sale of stocks or mutual funds that were omitted from your return. The IRS uses the total sales price as income without an offset for the cost or basis of the investment.
-
Step 3
Respond with a detailed explanation if you do not agree or partially agree. If the adjustment involves the sale of stocks or mutual funds, include your cost or basis in the adjustment items to reduce the proposed tax increase.
-
Step 4
Send in payment equal to the additional assessment if you agree with the adjustment of unreported taxable income as shown in the notice.
