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.
Federal income tax needs a permanent establishment, which a UK company selling online does not normally have. Sales tax is a state matter: some states tax software as a service and others do not, and registration is required once sales into a taxing state pass its threshold, commonly $100,000 a year.
The company registers for US federal payroll and in the employee's state, and withholds and reports tax there. A person working in the US can also create a taxable presence for the UK company, depending on what they do, which brings federal and state income tax returns.
In the company tax return for the period. An additional information form has to reach HMRC before the return is filed, and companies that have not claimed in the previous three years must notify HMRC within six months of the period end. A claim missing either step is rejected.
The UK company keeps filing its UK corporation tax return. The US parent reports the UK company on Form 5471 with its own return and includes income under the US rules for foreign subsidiaries, with credit for UK tax. Charges between the two are reported on arm's length terms in both.
