The tax treaty
In force
The United States and Latvia have an income tax treaty in force. It can lower the US tax withheld on dividends, interest and royalties paid to you, if you claim it on a W-8BEN with your Latvian tax number, and it settles which country taxes what when both could.
Stripe
Available locally
Stripe takes businesses registered in Latvia, so you don't need a US company to use it. A US LLC gets you a US Stripe account instead, paid out in dollars to a US bank, which helps when most of your customers are American.
Banking
No Mercury
Mercury doesn't open accounts for founders living in Latvia. It goes by where you live, not your passport, so a Latvian citizen living in another country may still qualify. Payoneer and Wise Business are the usual alternatives to check, and each has its own rules about where owners can live. Relay asks a non-US owner for a US address, an ITIN or Social Security Number and a US operating presence, so it rarely suits a founder living in Latvia.
The time difference
UTC+3
New York is 7 hours behind Latvia in summer. Everything we do is in writing, through your dashboard and email, and we reply within one business day, so the time difference rarely slows anything down.
