The result of a referendum on the UKs membership of the EU could have a significant impact on how actuaries work, according to the IFoA.
Nick Salter, president of the IFoA, said it was important that the issues were debated "so that informed decisions can be taken by the electorate".
"Whether the UK decides to remain part of, or leave, the EU could have a significant impact on pensions, insurance and investment," he said.
"It is important that the impacts on businesses and members of the public, in terms of regulation and financial products are properly understood and debated so that informed decisions can be taken by the electorate, something that is all too often missing."
Salter's comments followed the announcement of the EU Referendum Bill in the Queen's speech this week.
The bill allows for an in-out vote on the UK's membership of the European Union by the end of 2017.
On plans unveiled in the Queen's speech to devolve further powers to Scotland Salter warned this would raise a number of "complex issues" such as different tax rates.
"One such complexity is the potential for devolution to lead to differing tax rates in Scotland versus the remainder of the UK. This would increase complexity, especially in terms of tax relief on pension savings," he said.
Concerning pension reforms that came into effect last month, Salter said: "Any proposed legislative changes will need to avoid the possibility of unintended consequences, such as individuals gaming the system by declaring residency in the country with the more beneficial tax rates."
The IFoA welcomed government plans to tackle climate change but cautioned that there was a link between sustainability and the financial system.
Salter said: "Recent work by the IFoA revealed that there is a wider sustainability issue that needs to be addressed. Research suggests that the current growth-orientated economic model and financial system does not provide any incentive to fully recognise natural environment and resource constraints.
"It is important that we all take into consideration issues, such as climate change, that will have a impact on the long-term sustainability of our financial system."
