⦁   A notice of deficiency is usually triggered by tax information received from a third party filer–such as an employer or a financial institution–that does not match the information reported by the taxpayer.
⦁   A notice of deficiency is triggered by a taxpayer’s failure to timely respond to, or to successfully appeal, a pre-assessment letter known as a 30-day letter. This letter is to notify the taxpayer that his business did not file a tax return for a tax period in which the IRS believes he has a filing requirement. The letter notifies the taxpayer that the IRS has prepared a tax return on behalf of his business for the tax period identified.
⦁   If taxpayer agrees with the computation report of proposed adjustments to tax returns, he needs to sign and return the agreement form. If taxpayer does not agree, he can submit a request for appeal to the office/individual that sent the letter. The letter contains information and lists IRS publications on how to file an appeal/protest. The taxpayer needs to file his protest within 30 days from the date of this letter in order to appeal the proposed adjustments with the Office of Appeals.
