Is there really a 1-day free trial?

Yes. You get full access for 1 day. We collect a card up front so the transition is seamless if you keep going, but you can cancel any time during the trial and you will not be charged.

What happens after the trial?

On day 2 the subscription starts at $19/month. You can cancel from the customer portal Stripe sends you and keep access until the end of the period.

How is this different from TurboTax Premium + multi-state filing add-ons?

TurboTax Premium + multi-state filing add-ons, TaxAct with multi-state filing, and Hiring a tax professional for state compliance are mature platforms with a lot more surface area. This tool focuses on one job and ships it as a fast browser app — sign up free, upgrade in your account when you want Pro. The price is $19/month after the trial, versus around $130/month for the cheapest of those.

Can I cancel any time?

Yes. One click from the customer portal Stripe sends you. No retention call, no email gauntlet.

This was built specifically with Solopreneur Freelancers in mind, but anyone who needs the same outcome is welcome.

Does this work on mobile?

Yes. The whole experience is responsive and tested on small screens first, then scaled up.
