Questions? We've got answers.
How is Sails different from TaxJar?
TaxJar calculates tax at checkout and can file returns for you (AutoFile is billed per return). Sails focuses on the step before that: showing a small seller which states they're likely required to register in, and what to do next. Sails has a free plan; TaxJar's Starter plan is listed at $39/month with a 30-day free trial (checked September 25, 2026).
What happens after my free trial?
Paid plans start with a 14-day free trial and no credit card. If you add a card, your plan continues after the trial. If you don't, you move to the Free plan automatically — nothing is charged.
Can I change plans later?
Yes. Upgrade or downgrade anytime from Settings → Billing.
What does the free plan include?
Nexus monitoring across all 50 states + DC, threshold alerts, a filing calendar, unlimited tax calculations, and one store connection with up to 50 orders a month. The limit counts orders by the month they were placed, so you can import past months too, up to 50 orders in each. No time limit, no credit card.
Do you file my sales tax returns for me?
No. Sails shows you where you're likely required to collect, your deadlines, and your sales and tax collected by state, and you (or your accountant) file with each state. We'll only offer filing once the process has been reviewed by licensed tax professionals.
I'm just a hobby seller. Do I even need this?
Maybe not yet! Most states only require you to register once your sales into that state pass $100,000 a year (a few use a higher amount, and some also count 200 transactions). The free plan will tell you if you get close.
Is Sails a CPA or tax advisor?
No — we're software that helps you track and estimate sales tax. You review and submit returns yourself. For complex situations, we recommend consulting a tax professional.
