TL;DR: Online businesses must register just like physical businesses — the fact that you trade online does not exempt you from registration, tax, or compliance obligations.
A common misconception among new online business owners is that selling through a website, an app, or a marketplace platform requires less formal registration than a physical business. This is not correct. The legal and tax obligations that apply to business income apply equally whether you sell in a shop or through an online store.
Online businesses do, however, have some specific considerations: digital services VAT/GST rules that can create obligations in multiple countries, platform reporting requirements that alert tax authorities to online income, and consumer protection rules that apply specifically to online selling.
This guide covers the registration requirements for online businesses in the UK, France, Sweden, Australia, New Zealand, Canada, and the United States, and explains the specific considerations that apply to selling online.
Online businesses have the same basic registration requirements as offline businesses:
Business structure registration: Register as a sole trader, partnership, company, or other structure with the relevant authority in your country. Being an online business does not change which structure is appropriate or how to register it.
Tax registration: Register for income tax / self-assessment as a self-employed individual (sole trader) or register the company for corporation tax. All business income — whether received via PayPal, Stripe, bank transfer, or a marketplace — must be declared.
VAT/GST registration: Register for VAT/GST when your taxable turnover exceeds the registration threshold in your country. For online businesses selling to consumers in other countries, additional digital services rules may apply (see below).
Business name registration: If you trade under a name different from your own name or your company's registered name, register the trading name.
The rules for VAT/GST on digital services (software, streaming, downloads, online courses, SaaS products) have become increasingly complex.
EU/UK rules: If you sell digital services to consumers (not businesses) in the UK or EU, you may need to collect and remit VAT in those countries — even if you are based elsewhere. The UK introduced its own system post-Brexit; the EU uses the One Stop Shop (OSS) scheme. These rules apply from the first sale — there is no registration threshold for non-resident digital service providers.
Australia: The GST rules apply to sales of digital products and services to Australian consumers by non-resident businesses with turnover above A$75,000 from Australian sales.
USA: US sales tax on digital products varies by state. Some states tax digital goods; others do not. Multi-state compliance for digital businesses is complex.
Practical implication: If you sell digital products or services to consumers globally, you may have VAT/GST obligations in multiple countries. This is a significant compliance burden. Many small online businesses use tax compliance software (Quaderno, TaxJar, Avalara) to manage this automatically.
Major online marketplaces — eBay, Amazon, Etsy, Airbnb, Fiverr, Upwork, and others — are increasingly required by law to report seller income to tax authorities. In the UK, the HMRC DAC7 regulations and in the EU, the DAC7 Directive require platforms to report the income of sellers who meet certain volume or value thresholds. In the USA, platforms report payments above US$5,000 per year (as of 2024 implementation).
This means that income from marketplace selling will be visible to your tax authority regardless of whether you declare it voluntarily. Failing to declare it and having it subsequently discovered creates significant penalties.
If you sell goods or services to consumers online, consumer protection laws impose specific obligations:
Distance selling / e-commerce regulations: In most countries, online sellers must provide clear information about the business, the product or service, prices, delivery timescales, returns and refund rights, and complaint procedures. Consumers typically have a right to cancel certain online purchases within a cooling-off period (14 days in the UK and EU).
Privacy and data protection: Online businesses collect personal data (email addresses, payment information, browsing data). GDPR in the UK and EU, the Privacy Act in Australia, PIPEDA in Canada, and various US state laws (CCPA in California) impose obligations on how you collect, store, and use this data. A privacy policy is mandatory.
Cookie consent: If your website uses cookies, you must obtain appropriate consent from visitors under GDPR (UK and EU).
If you accept card payments, you must comply with PCI-DSS (Payment Card Industry Data Security Standard). Using a reputable payment processor (Stripe, Square, PayPal) that handles PCI compliance on your behalf is the practical solution for most small online businesses.

Q: Do I need to register if I sell only through a marketplace like Amazon or Etsy?
Yes. Selling through a marketplace does not exempt you from business registration and tax obligations. Marketplace sellers are required to register for tax, declare all income, and may need to register for VAT/GST. The marketplace may collect and remit VAT/GST on your behalf (as Amazon does in some jurisdictions) but does not handle your income tax obligations.
Q: Do the same rules apply to dropshipping businesses?
Yes. Dropshipping businesses are treated as regular businesses for registration and tax purposes. The fact that you do not hold inventory yourself does not affect your registration or tax obligations. Cross-border VAT and customs duty rules add further complexity for dropshippers.
Q: I sell digital products to global customers. Do I need to register for tax in every country?
Potentially, yes — but most countries have thresholds below which the obligation does not apply. For EU/UK digital services VAT, there is no threshold for non-resident businesses. For Australia, NZ, and Canada, thresholds apply. The practical answer for most small businesses is to register where the rules clearly require it and use tax compliance software to manage calculation and remittance.
