Why this hub exists

Most contractor payment content is written for the worker, not the payer. That leaves US founders, AP teams, and finance leads guessing on the rules that actually trigger penalties. The IRS calls this body of rules NRA withholding, and the obligations live with the US payer, not the foreign recipient. This hub is the canonical Omnivoo entry point for those rules, with links down to the pillar guides and to the practical country playbooks that put them to work.

The five pillars

Each pillar covers one concept that a US payer has to get right. Together they cover the territory most competitors mention once and move on.
