Factual error: When Medina and the IRS Agent are searching through the database to check Paul's Laundromat's tax return, it's mentioned that Paul's Laundromat is a partnership, with Christian Wolff as a managing partner. However, the tax return shown on the screen is a Form Schedule C which is a form filed with a personal 1040 tax return. A partnership should be using Form 1065 with a schedule K1 to flow through to a form 1040. (01:18:17)
