We will complete a form 8821 for the tax years in question and have you sign it. We can then call the IRS and request income transcripts, which they can usually fax within 48 hours. The transcripts contain wage and income records that are required to be reported to the IRS by employers, banks, financial institutions, brokers, pension funds, etc. This information will show any federal taxes withheld, social security and medicare. This will give us most of the information we need to prepare the federal return. If you are self-employed and are lacking records, the IRS allows you reconstruct mileage records, use per diems for travel expenses, etc.
