How Donald Trump’s Presidency Could Impact Retirement Rules

Your retirement accounts may be the biggest component of your net worth. Or maybe those large balances are still only a goal, and you want to know if any changes coming in the next four years will help you get there — or get in your way.

Of the 1,200 or so money-related questions we’ve received from readers in the days since the presidential election, many have been about retirement. We have some answers for what we know and context for what we don’t yet know. Most of them have nothing to do with Social Security; my colleague Tara Siegel Bernard answered questions about that program last week.

But first, here’s an important caveat that is true in any administration, but especially in one like this: For things to change, President-elect Donald J. Trump has to want things to change, act on that desire and then succeed. If lawmakers are involved, they also have to have the desire, follow through and pass legislation.

There will be plenty of noise, but in this particular category, it’s possible that not much of substance will look different four years from now.

What did Mr. Trump say he wanted to change about individual retirement accounts or 401(k)s?

Not much. Neither Mr. Trump’s campaign website nor the Republican Party platform that it pointed to said anything about I.R.A.s or workplace retirement accounts like 401(k)s, with one exception that probably wouldn’t affect many people.

On his campaign website, Mr. Trump sounded off about environmental, social and governance, or E.S.G., funds and their place in workplace retirement plans. During his first term, the Labor Department issued a rule related to what sorts of funds an employer — which must act in employees’ best interest as a so-called fiduciary — can use in those plans.
