Profit split method — do I need an adviser, or can I do it alone?
Some of it, yes — and we will say so on the call if that is the honest answer. The parts that are worth paying for are the ones where a missed election, a missed deadline or an unverified threshold costs more than the fee: it divides the combined profit by reference to the parties' relative contributions, often measured by costs, assets or headcount tied to the value drivers.
What if I have already filed and got it wrong?
That is a common starting point. We re-derive the position, identify whether an amendment or a disclosure route is the right vehicle, and tell you which one preserves the relief that is still available. The order matters more than the speed.
How long will it take?
It depends on the documents rather than on us. Once the pack is complete most filings turn around inside a fortnight; anything that needs a certificate from a tax authority runs on that authority's timetable, which we tell you at the start rather than at the end.
When should we use a profit split instead of a margin method?
When both sides make unique and valuable contributions, so neither can be treated as the routine party whose return is tested against outside comparables. That is the real test, and it is a question about the functional analysis rather than about convenience. Highly integrated operations, where the parties share the risk of the same outcome and cannot sensibly be evaluated apart, point the same way. If one side is genuinely routine, a one-sided method is simpler, better evidenced and harder to argue with, and choosing a profit split there creates work without improving the position.
How do we justify the factors used to split the profit?
By tying each factor to something that actually drives the profit being divided, and showing the link in the functional analysis rather than asserting it. If the value comes from development work, a factor built on development costs or on the people doing that work can be defended. If it comes from a customer base one side built and maintains, a factor reflecting that activity can be. The weak version picks a factor because the data exists, revenue or total assets, and explains afterwards why it is reasonable. Expect a reviewer to ask what the outcome would be under a different factor.
Can we use a profit split if only one side is unique?
That is usually the signal to use a different method. Where one party contributes something unique and the other performs routine functions, the routine party can be tested against outside comparables and given the return those comparables support, with the remainder falling to the unique contributor. A full profit split in that situation divides profit between a party whose return is observable and one whose return is not, which throws away the better evidence. A residual analysis is the middle ground: routine returns priced first, then the remaining profit divided by reference to the unique contributions.
Do we still need comparables data for a profit split?
Less of it, and for a different purpose. The method does not rest on finding companies with the tested party's profile, which is why it is reached for when no such companies exist. Comparables still appear in a residual analysis, to price the routine returns before the remainder is divided, and external data can support a splitting factor or corroborate the outcome. The main evidence base, though, is internal: the functional analysis, the agreements, and the accounting records showing where the costs and the people sit. That shifts the preparation work from searching to documenting.
Is headcount a defensible way to split profit?
It can be, where the people are the value driver and the roles counted are the ones that matter. Counting everyone employed by each side rarely is; counting the people performing the functions the profit comes from can be. The factor also has to be measurable on the same basis on both sides, which is where it often fails: different job titles, contractors on one side and employees on the other, shared roles divided by estimate. Document how the count was taken and from which records, because a factor a reviewer cannot reproduce is a factor they will replace.
What records do we need to defend a profit split in an audit?
The functional analysis first, in enough detail that a reader can see why neither side is routine. Then the agreements, showing how the parties share the outcome and the risk of it. Then the data behind the splitting factors, traceable to the systems it came from, with the basis of any allocation written down. Finally the combined profit itself: which entities, which transactions, which period, and the adjustments made to put both sides on the same accounting basis. The weakest point in most files is that last item, because it is assembled once and rarely explained.
What is transfer pricing?
The meaning of transfer pricing is narrow and specific: it is how related companies in a group price what they sell each other — goods, services, financing, the use of intellectual property. Tax law requires those prices to be what independent parties would have agreed, the arm's length principle, so profit is not simply moved to a lower-taxed country. Canada tests it under s.247, the US under s.482, India under s.92, and each expects documentation prepared contemporaneously. See transfer pricing documentation.
What is an advance pricing arrangement?
An agreement with a tax authority, in advance, on how a category of intercompany transactions will be priced for a set number of years. Unilateral arrangements bind one country; bilateral or multilateral ones bind both sides of the transaction and are what actually removes the risk of an adjustment in one country without relief in the other. They take real time and full disclosure, so they suit large recurring flows rather than one-off transactions. See our transfer pricing work.
