Expert US sales tax and UK VAT registration, calculation, and filing services that keep your e-commerce business fully compliant across every market you sell in.
For e-commerce sellers operating in the US and UK markets, sales tax and VAT compliance is one of the most complex and frequently misunderstood areas of business taxation — and one of the most consequential if handled incorrectly. In the United States, sales tax is governed at the state level with over 10,000 different tax jurisdictions each with their own rates, rules, and product taxability determinations. In the United Kingdom, VAT is a federal system but carries significant compliance obligations for registered businesses. Eboostory provides expert sales tax and VAT services that ensure your business collects, reports, and remits the correct amounts to the correct authorities on the correct schedule — keeping you fully compliant in every market you operate in.
Before you can comply with US sales tax obligations, you need to understand where you have nexus — the legal connection to a state that triggers a sales tax collection obligation. Economic nexus laws, introduced following the South Dakota v. Wayfair Supreme Court decision, mean that sellers crossing certain sales volume or transaction thresholds in a state must collect and remit that state's sales tax regardless of physical presence. We conduct a comprehensive nexus analysis for your business, identifying every state where you have current or potential sales tax obligations based on your sales history and business activities.
Once nexus is established in a state, you must register for a sales tax permit before collecting tax from customers in that state. We handle sales tax permit registrations across all states where your business has nexus — completing the registration applications, obtaining your permit numbers, and confirming your collection obligations in each state so you are legally authorized to collect and remit sales tax everywhere you are required to do so.
We prepare and file your sales tax returns across all registered states on the required filing schedule — monthly, quarterly, or annually depending on your sales volume in each state. Every return is prepared with accurate sales data, correct tax calculations accounting for the applicable rates and any applicable exemptions, and submitted on time to avoid late filing penalties. We also manage the remittance of collected sales tax to each state tax authority on the correct schedule.
UK businesses must register for VAT once their taxable turnover exceeds the current registration threshold, and many e-commerce sellers importing goods into the UK or selling to UK customers have VAT obligations regardless of where they are based. We handle UK VAT registration with HMRC, prepare your quarterly VAT returns under Making Tax Digital (MTD) requirements, calculate your VAT liability or reclaim position accurately, and submit returns and manage payments on the correct schedule. We also advise on the correct VAT treatment for your specific products and business model, including the import VAT implications for goods shipped into the UK.
Sales tax and VAT compliance is not a one-time exercise — thresholds change, rates are updated, new nexus obligations arise as your business grows, and both the IRS and HMRC periodically update their requirements and procedures. We provide ongoing compliance monitoring that tracks your sales against nexus thresholds in new states, alerts you to rate changes affecting your products, manages registration renewals, and ensures your compliance obligations evolve correctly alongside your growing business.
