Check your hustle — free

Freelancers and side hustlers owe 15.3% SE tax on net profit above $400/year, plus federal income tax. The checker calculates your estimated liability and tells you whether quarterly estimated payments apply to you.

Most side hustlers are automatically sole proprietors — no paperwork needed. The checker tells you whether your income level and liability risk warrant forming an LLC, and at what point an S-corp election saves meaningful taxes.

Some states require a business license even for Etsy shops and digital product sellers. The checker evaluates your state and hustle type to flag any license or permit requirements you might not know about.

Marketplace facilitator laws mean Etsy, Amazon, and eBay collect and remit sales tax in most states — but not all situations are covered. The checker flags whether you have any remaining sales tax obligations.

Home office, equipment, supplies, software subscriptions, shipping, and mileage are all potentially deductible — but most side hustlers miss at least a few. The paid report gives you a personalized deduction checklist based on your hustle type.

Quarterly estimated tax is due April 15, June 15, September 15, and January 15. Miss one and you'll owe an underpayment penalty. The checker surfaces which deadlines apply to you so you're never caught off guard.
