Who pays tax when AI agents trade?

AI trading agents can select strategies, execute trades and pay for services without approval for each transaction. Unlike conventional trading bots that follow predetermined rules, these systems pursue user-defined objectives within specified limits. Their activity can create extensive tax reporting obligations, with token swaps and payments for data or computing each potentially constituting a disposal.

UK law gives software no legal personality, so an agent cannot own assets, enter contracts or pay tax. Liability generally follows beneficial ownership of the assets it controls. Most individuals using agents are likely to remain subject to capital gains tax rather than being treated as traders, although substantial involvement in developing and adjusting a strategy can complicate that assessment. Reliable agent logs, blockchain data and account records are essential.

Companies remain taxable on trading profits, while offshore structures can raise questions about corporate residence, permanent establishments and anti-avoidance rules. Transferring funds to an ostensibly independent agent does not necessarily separate the deployer from subsequent income or gains. Retained control, possible repayments and indirect benefits can preserve tax exposure, even where access to the funds has been surrendered.

Argentina has proposed a corporate category for AI-run entities, although the draft still requires human involvement. UK regulators and the EU continue to place obligations on existing legal persons rather than granting agents independent status. Establishing ownership, control and access to transaction records remains central to compliance.
