VAT / Sales Tax
Standard rate 20%. Registration threshold: 90,000 GBP. Non-UK businesses providing digital services to UK consumers must register for and charge UK VAT, with no registration threshold applying to these cross-border B2C sales.
Banking & payments for SaaS Startup
Opening a traditional high-street bank account in the UK is notoriously difficult for non-resident founders, often requiring a UK-resident director and an in-person branch visit. However, non-residents can easily open accounts with digital fintech platforms like Wise or Revolut Business, provided they pass strict KYC and AML checks. Having a clear business plan and proof of UK trading activities significantly improves approval chances.

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?
You need a business bank account and a payment gateway like Stripe, or a Merchant of Record like Paddle or Lemon Squeezy. These services require your company to be incorporated in a supported country.
