Affluent savers may soon lose a big chunk of a strategy that allows them to pass on large individual retirement account balances to their children and grandchildren.

The change is part of proposed legislation called the Retirement Enhancement and Savings Act of 2016, which easily passed the Senate Finance Committee in September.

The rule change still has to pass the Senate and the House, and then be signed by the president. Nevertheless, if it becomes law, the bill would require balances in most inherited IRAs and 401(k) plans to be distributed within five years of a saver's death. One factor behind the bill's appeal is that it will generate an estimated $3.18 billion in revenue from 2017 to 2026.

Currently, heirs who inherit these accounts can take distributions over the course of their own lifetimes, meaning the balances can grow tax-deferred or even tax-free, in many cases, for decades.

There is a provision in the bill that allows beneficiaries to exclude up to $450,000 from the five-year rule, meaning that amounts in excess of that threshold would be subject to the quicker payout — and possible taxes on the distributions.

The proposed legislation pokes a big hole in these so-called "stretch IRA" strategies.

"With a stretch IRA, you give a young beneficiary the gift of long-term tax deferral," said Jeffrey Levine, chief retirement strategist at Ed Slott and Co. in Rockville Centre, New York.

This isn't the first time the stretch IRA has been on the endangered list.

Last year, President Barack Obama proposed a similar measure in his 2016 budget. The change didn't happen.

Tax experts are a little more uncertain this time, with a Republican Congress and Donald Trump in the White House next year.

"I think Republicans have been more apt to leave the stretch IRA rules in place, but this could be used as a bargaining chip [in budget discussions]," said Levine.

For instance, in late 2015, Congress passed its Bipartisan Budget Act — along with sweeping changes to Social Security that largely did away with "file and suspend" and "restricted application" strategies.

The overhaul to the government's retirement income program was tacked onto the budget bill at the last minute and was subject to little debate. That can very well happen again.

"I could see something similar happening here, where it isn't a priority item on the agenda for the legislature and the president-elect," said Levine. "But if it's a bargaining chip, it might sweeten the pot a little for the other side."

A five-year payout of inherited IRA balances could also help fill the federal coffers if "it's used as a revenue tool," said Stephen Bigge, partner with Keebler & Associates in Green Bay, Wisconsin.
