What the role actually covers
The word compliance matters: the job is meeting obligations correctly and on time, distinct from tax planning. In the UK alone that means online Self Assessment returns by 31 January after the tax year, payments on account by 31 January and 31 July, and for companies a Corporation Tax return within 12 months of the period end with tax payable within 9 months and one day. Multiply that by several countries with different year-ends and a central tracker becomes essential. The manager files what they are placed to handle, coordinates trusted local specialists for the rest, and makes sure double tax relief and treaty positions are claimed so the same income is not taxed twice. Our full guide to the global compliance manager role sets out each strand.
Who needs one, and who does not
The trigger is connection to more than one country with no single person owning the whole picture: business owners with companies in several countries, individuals who have moved or split their time across borders, non-residents letting UK property alongside home-country rules, and founders hiring abroad with payroll or permanent establishment exposure. The manager also watches the risks that only exist because borders are involved, such as company tax residence and CFC rules, where the place directors actually take decisions can change which country taxes a company. If all your tax sits in one country, a good local accountant is enough; the case grows with each country, entity or income source you add. If you are relaying information between advisers or reconciling figures yourself, that is the signal.
How it is priced and how an engagement runs
An engagement starts with a scoping review that maps every country and builds a complete inventory of obligations, because until that map exists any quoted figure is a guess. A fixed annual fee is then agreed against the scoped work, reflecting the number of jurisdictions, entities and returns and whether higher-complexity risks such as transfer pricing or permanent establishment apply, and many clients spread it monthly or quarterly. The ongoing cycle is tracking deadlines, preparing or commissioning returns, reconciling figures across countries and handling tax authority correspondence, with the scope revisited whenever your footprint changes. This is the model Horizon runs for clients managing tax across multiple countries: fixed fees agreed upfront, one accountable adviser, and a free clarity call at /book to scope your position.
