The main thing you’re going to need to get your hands on for tax season is your full year’s accounting from Quickbooks. If you’ve been keeping track along the way, this is super easy. Go to the “Reports” section of Quickbooks and you’ll be able to see all your categorized expenses. However, even if you haven’t kept track all year, you can take the time to go through all your transactions at once and categorize them properly (this totally works, just takes longer come tax time). You’ll also need your EIN handy for TurboTax.
