What we handle for you
The filings this sector needs most, on both sides of the Atlantic.
Questions this sector asks first
The general position on each. What applies to you depends on where you live, where the work is done and who pays.
Once sales into a state pass that state's threshold, commonly $100,000 in a year, or as soon as stock is stored there. Using a US fulfilment service places inventory in particular states and creates the obligation from the first sale. Marketplaces usually collect the tax on sales made through them.
Yes, if it has no UK establishment and sells goods that are in the UK at the point of sale: the £90,000 threshold does not apply to overseas sellers. For consignments valued at £135 or less sent from abroad, VAT is charged at the point of sale, by the marketplace where one is used.
Only where there is a taxable presence. Under the treaty a company is taxed on its profits in the other country if it has a permanent establishment there. Stock held in a warehouse purely for storage and delivery does not normally count on its own, though it does create sales tax obligations.
Sales are converted to the reporting currency at the rate on the transaction date or a consistent average. Balances held in dollars or pounds produce exchange gains and losses, which are part of taxable profit. The US and UK returns each use their own currency, so the two never show identical figures.
