FINRA is urging the public to use offshore tax havens, saying they can be used to hide funds from taxes.
The regulator said it had received complaints from around the world that money was being moved offshore to avoid paying taxes, but was unsure how to proceed.
It said it would send a warning to anyone using offshore tax avoidance schemes to ask them to explain their actions.
Its advisory committee has issued a report outlining its views on offshore tax evasion.
It also said that, while tax avoidance is illegal, it was not illegal to pay a foreign tax.
Tax evasion is often used as a pretext to avoid taxes, such as the withholding of taxes on money or other property.
But FINRA said it was concerned that many tax evaders used a legal, but often not legal, method to avoid tax.
It has also raised concerns about the quality of offshore financial institutions and the amount of money that is held offshore.FINRA said that there was a lack of transparency in how offshore financial centres were managed.
It was also concerned about the extent to which taxpayers and their families were being misled about how much they are actually owed.
It warned that tax evasion had grown over the past 10 years and that there is a risk that tax avoidance could be used by unscrupulous individuals to avoid reporting the correct amounts to authorities.
The report found that in 2017, a further 6% of all overseas tax evades were reported by overseas financial institutions to tax authorities, compared with the same year a decade earlier.
FINRA recommended that the government consider setting up a new national network to monitor offshore financial centers and to enforce compliance with tax law.
Its chief executive, Peter Lewis, said: “It is vital that offshore financial secrecy is maintained and that it is only possible to do so if the public is fully aware of the scale of the problem.”
Tax evasion can often be used as the basis for legal claims and financial planning and, if not reported properly, can make it very difficult for the government to collect the taxes due.
“For too long, the government has relied on secrecy to avoid taking tough action.”
The regulator is also concerned that the extent of money being moved abroad is increasing.
It recommends that countries should be required to declare the money held in offshore financial havens to tax officials.
In addition, FINRA also recommends that foreign governments and international bodies be required by law to report the amount and type of money in offshore tax haven accounts.
