I'm based out of India and hate the Taxation system here (it's worse than what you read for the US) - software attracts Service Tax and VAT (Sales Tax) both - you pay reverse service tax for services you take from abroad and you even pay TDS (Withholding Tax) from your pocket for entities not incorporated in India. I could just go on and go on here.... it's just stupid.
I'm planning to incorporate my startup soon and want to do it in a country where I can: 1) Use a PG like Stripe. 2) No Service/Sales Tax just flat out corporate tax on profits. 3) Easy, Simple and Affordable Registration and maintenance process.
