How AIM-capable software works

AIM-capable software works out business AIM profit which is the total profit (or loss) for a specific period including adjustments.

When integrated through our gateway services it lets businesses:

  • check if they're eligible to use AIM
  • file statements of activity
  • query losses and residual taxes
  • query period balances
  • retrieve statements of activity already filed.

Take a look at our AIM software developer kit (SDK) or find out more about AIM, the eligibility criteria, statement of activity and working out payments.
