Software Development Agency FAQ
Where is the best place to incorporate a dev agency?
Estonia is great for reinvesting profits without immediate tax, while a US LLC (Wyoming or Delaware) is excellent for global invoicing and accessing US clients.
How do withholding taxes affect my agency?
If your client's country doesn't have a tax treaty with your company's jurisdiction, they might be required by their local laws to withhold a percentage of your invoice amount.
Do I need to charge VAT or GST to my clients?
It depends on the location of your clients. B2B software services exported outside your jurisdiction are often zero-rated, but you must verify local reverse-charge rules.
