Ask HN: How does your SaaS company handle charging sales tax?
Hello,<p>For my SaaS company, I charge my customers via Stripe, PayPal and some other payment platforms. Sales tax is different in every country, and in the US it is even different per state.<p>How does your SaaS company handle sales tax? Do you use the country and secondary (zip code or state) of the saved credit card or have some sort additional form? I can imagine a scenario where company A is based in California but uses a credit card from NY. In that case they should pay CA sales tax but if I were to use their credit card information, it would be NY sales tax.<p>This feels like a problem that has been solved by any international (or just US) SaaS company. Any tips would be greatly appreciated!
