Standard rate 0%. Hong Kong does not levy any Value-Added Tax (VAT), Goods and Services Tax (GST), or sales tax on goods or digital services.
Banking & payments for SaaS Startup
Opening a traditional corporate bank account in Hong Kong for a branch office is notoriously rigorous due to strict AML/KYC regulations. Banks require extensive documentation on the foreign parent company, its directors, and ultimate beneficial owners, often necessitating an in-person visit. However, fintech platforms like Airwallex and Statrys offer faster, remote-friendly alternatives for multi-currency accounts.

SaaS Startup FAQ
Where is the best place to incorporate a SaaS startup?
Delaware (USA) is the gold standard if you plan to raise venture capital. For bootstrapped founders, Estonia (OÜ) or the UK (LTD) offer great digital infrastructure and tax efficiency.
Do I need to charge VAT/Sales Tax to global customers?
Yes, most jurisdictions require you to collect VAT or Sales Tax based on the customer's location, even if your company is based elsewhere. Using a Merchant of Record (MoR) can simplify this.
How do I accept recurring payments?
