Frequently Asked Questions

Will work with Stripe, Paypal, or other merchant accounts?

Yes. You can connect payment gateways such as Stripe or PayPal to your Mercury account to receive merchant payments.

Will open a business bank account for my new company?

Yes. A free, FDIC insured, business bank account is part of our package for our customers. We’ll help you quickly set up a US business bank account through our partner, Mercury Bank. Spend $10k and get a $500 bonus - only for customers.

Do I need to pay taxes in the US?

Generally, if the members or shareholders of a US company are foreigners and the entity doesn’t have any US-connected income, this company won’t have any tax liability in the US. Just selling products or services through your US company doesn’t make you subject to US taxes — even if you are selling to customers based in the US. We always recommend that you speak with a tax expert for your individual situation.

How are we different from other services?
