International GST/VAT Thresholds and Compliance Matrix

⏳ 2 min read

Registration limits, tax rates, and filing guidelines for self-employed developers in the US, UK, and Australia.

Global GST and VAT Registration Thresholds

Tech freelancers selling digital goods or B2B services internationally must carefully track local sales tax registration thresholds. Once your gross turnover (revenue) exceeds these limits over a trailing 12-month period, you are legally required to register, collect, and remit sales tax/GST/VAT.

JurisdictionSales Tax NameRegistration ThresholdStandard Rate
**United States**Sales Tax (State-level)Varies wildly. Usually $100k in gross sales or 200 separate transactions into a specific state (Economic Nexus).0% - 10%
**United Kingdom**Value Added Tax (VAT)£90,000 (rolling 12 months)20%
**Australia**Goods and Services Tax (GST)$75,000 AUD (annualized)10%

Exporting Services & Zero-Rating

For Australian and UK freelancers exporting software development services to overseas B2B clients (e.g., a UK developer contracting for a US-based corporation), the service is generally **zero-rated** (exempt from VAT/GST).

However, there is a massive caveat: You must still track that zero-rated gross revenue. It counts toward your overall registration threshold. Once you cross the threshold, you must register for VAT/GST, even if all your clients are overseas and your effective tax collection rate remains 0%.

Reverse Charge Mechanism

When providing B2B digital services internationally (especially within Europe), the 'Reverse Charge' mechanism shifts the liability of paying the VAT from the freelancer to the buyer. Always ensure your invoices explicitly state 'Reverse Charge Applies' when utilizing this.

Frequently Asked Questions

Q: What happens if I cross the VAT/GST threshold mid-year?

Thresholds are usually calculated on a rolling 12-month basis. Once you exceed the limit, you generally have 30 days to officially register with the tax authority and begin charging tax on new invoices.

Q: Do I charge VAT/GST to foreign clients?

Usually no. B2B services exported to foreign countries are typically 'zero-rated' or fall under the reverse charge mechanism. However, you must still be registered if your total global income exceeds the threshold.

Q: What is Economic Nexus in the US?

In the US, you don't need a physical office in a state to owe them sales tax. Economic Nexus laws mean that if you sell a certain amount of digital goods into a state (e.g., $100,000), you must register and collect sales tax for that state.
