What to Gather as Tax Season Approaches
As January comes to a close, business owners will begin receiving 1099s and other tax documents over the next several weeks. Forms may arrive at different times by mail or email. For many business owners, this is also the moment they begin thinking about records that were pushed aside during a busy year. Having your documents ready for your tax professional reduces delays in filing and leads to a more accurate return.

Each tax season, it's common for business owners to start thinking about all the bookkeeping and accounting work that didn't get done through the year. Your books need to be organized and current for the best possible outcome on your tax return. If you haven't tracked income and expenses all year, you'll need to hire someone to get your books in order. This gives your tax professional a full picture of your financials which will determine the complexity of your tax return.
This tax filing checklist outlines the information and documents commonly needed to prepare a business tax return. Every business is different and your return may require additional information, but this tax checklist serves as a starting point for the most common documents need to file your tax returns.
