Online tax filing softwares range in price, from free filing through Credit Karma Tax all the way to TurboTax Self-Employed for a little over $100. Uber has some discounts on tax filing options that you can read about in the Rewards section of your Partner account.
Stride also offers a discount for tax filing with H&R Block's online filling product, which you can access here.
If you know you have a complicated tax return and are willing to spend a little extra for a tax preparer or CPA, then you could hire a licensed tax preparer. For one of these individuals (like a CPA, tax attorney, or EA), you’ll typically pay between $100-$450 per hour.
There are also a number of free tax preparation nonprofits that will help you at no charge, depending on your income. You can read more about some of these free programs here.
