Hi Kimdominguez!
Thank you for this question. The very first thing that you'd need to file the 2021 tax return is to collect all of your income and expenses. Expenses are important because they can be used to mitigate the amount of taxes that you may have to pay. If you are claiming dependents, you would of necessity have the information to claim them. Once you have your tax info collected and at your disposal, you'll need to buy the software. Here is a link for the software:
