The tax preparer (bot or human) will help determine the appropriate tax form for you. As a first-time filer, it will likely be the 1040EZ. You will manually input or digitally import your aggregate income, credits, and deductions. Deductions lower taxable income, and credits reduce the amount of taxes you owe. Each section will be calculated to conclude whether you can expect a tax return or a tax bill. May the odds be ever in your favor.
