I would take the risk and not pay taxes if I were 17 making $500 a month. Your income probably isn't high enough to require tax filing. Plus if you do file, your age is going to let you reduce so many things you won't pay anything anyway.
Now if you know ahead of time you won't have to pay anything, I think you're supposed to declare anyway. Reduce your site expenses. Reduce any paypal fees you're paying. Get receipts for pencils, pens, and office supplies. If you don't need that, what do you need? Need a new laptop. You need it for business. Go reduce that.
Really, if you're making $500 a month you can reduce everything with frivolous expenses. I guess you're still buying things you might otherwise not purchase, but it's better than getting nothing. Don't buy an ice cream maker or something ridiculous, but basic business expenses won't raise any red flags, and it's not unlikely for someone making a $500 business income to have even a $0 profit.
There are likely billions of dollars lost by taxpayers because they don't reduce eligible expenses. Save receipts for everything now and figure out what to do later if you want.
