Retirement compensation arrangements
Retirement compensation arrangements (RCAs) are defined under subsection 248(1) of the Canadian Income Tax Act, which allows 100 per cent tax-deductible corporate dollars to be deposited into an RCA, on behalf of the private business owner and/or key employee. No tax is paid by the owner/employee until benefits are received at retirement.
