Sell some stuff on Etsy and get payouts on social media. As soon as you start adding in business expenses, it inflates pretty quickly.

I've often taken on a side project or two a year for software dev/consulting and it usually winds up being $200-350 to have my taxes done. If I only have W2 income, I'll do the electronic version of TurboTax though. I also do 0 deductions and have extra out of each check taken out just in case, I don't set aside or do quarterly payments and usually get a decent return back.
