Tax Return Documentation Checklist


January 17, 2020

The beginning of the year is an exciting time for many businesses. It represents the opportunity to implement new strategies, attack new sales, production, and other goals, and improve performance from the prior year. It provides the same opportunity for individuals who have been working hard and looking to tackle new professional challenges. For management and employees alike, the holiday break offers needed time away to refresh and recharge for the opportunities and challenges that lie ahead. While the excitement is a good thing, it’s important not to forget about 2019 completely, specifically your 2019 tax return. Before meeting with your tax accountant, it’s essential to review a list of required items necessary to complete the filing. While each taxpayer is different, both individual and business, there are standard items required for each to prepare the returns. To help clients, prospects, and others, Klatzkin has provided a summary of the documentation requirements our firm has for taxpayers below.
