Two retired coworkers at the same agency, born six months apart, sat down for coffee in early 2020 and compared notes. One, born in June 1949, had just taken her first required minimum distribution from her TSP and IRA. The other, born that July, had been told he could wait two more years. Same agency, same grade, nearly the same birthday. Different rules.

That quirk came courtesy of the SECURE Act, signed on December 20, 2019 and effective January 1, 2020. It was the biggest retirement law in over a decade, and it reached into the accounts most federal savers rely on: the Thrift Savings Plan and traditional and Roth IRAs.

Here is what actually changed, and what it meant for people with federal careers behind them.

The required minimum distribution age moved to 72

Before the law, you had to begin required minimum distributions (RMDs) the year you turned 70½. The SECURE Act pushed that to 72 for anyone who hadn't reached 70½ by the end of 2019. That is why the June and July birthdays landed on opposite sides of the line.

For TSP participants, the practical effect was two extra years of tax-deferred growth and more room to plan withdrawals. The TSP's rule has always had a federal twist: RMDs generally begin by April 1 of the year after you turn the required age and have separated from service, whichever comes later. So a still-working federal employee past the threshold isn't forced to draw down the TSP, though IRAs follow different rules and have no such exception.

One caution. This number kept moving. The SECURE 2.0 Act of 2022 raised the age again, to 73 starting in 2023 and 75 starting in 2033, depending on your birth year. Check irs.gov for the age that applies to you.

The age cap on IRA contributions disappeared

Under the old law, you couldn't put new money into a traditional IRA after 70½, even if you were still drawing a paycheck. The SECURE Act repealed that cap starting in 2020.

You still need earned income to contribute, and the usual annual limits apply. Those limits are adjusted periodically, so look up the current figure at irs.gov. But for the federal retiree who takes a part-time contract job, consults for a former agency, or simply works past 70, the door stays open. Roth IRA contributions never had an age limit, so this change mostly evened things out for traditional IRA holders.

The "stretch" for inherited accounts was largely shut down

This was the change with the biggest consequences, and the one many families didn't see coming.

Before 2020, a non-spouse beneficiary who inherited an IRA could generally spread withdrawals over their own life expectancy. A 45-year-old inheriting an account might have stretched distributions across nearly four decades, keeping the tax bill small and the money compounding.

The SECURE Act replaced that with a 10-year rule for most non-spouse beneficiaries of owners who died after 2019. The inherited account generally has to be emptied by the end of the tenth year following the owner's death.

Picture a retired federal employee who leaves a $400,000 traditional IRA to her 45-year-old daughter. Under the old rules, the daughter might have withdrawn modest amounts annually for decades. Under the new rules, she has a decade. Averaged out, that is roughly $40,000 a year plus growth, stacked on top of her own salary, potentially pushing her into a higher bracket. Timing the withdrawals across the ten years, rather than waiting until year ten, can make a real difference.

Who still gets favorable treatment

The law created a category called "eligible designated beneficiaries," who can still use life-expectancy payouts. That group includes:

  • A surviving spouse
  • The owner's minor children (until they reach the age of majority, after which the 10-year clock starts)
  • Disabled or chronically ill individuals
  • Anyone not more than 10 years younger than the account owner

Spouses remain the most flexible beneficiaries, which matters for the many federal couples naming each other on everything.

What it means for the TSP

The TSP has its own beneficiary rules, which are narrower than those for IRAs. A spouse can generally keep an inherited TSP account, while non-spouse beneficiaries typically receive a payout or can move the money to an inherited IRA. In that case the 10-year rule governs the IRA that receives it. Confirm the current options at tsp.gov before making assumptions, because TSP procedures and the IRS's guidance on how annual withdrawals work during the 10-year window have both evolved since 2020.

This also gave federal savers a reason to revisit Roth conversions. Leaving heirs a Roth balance means they still face the 10-year deadline, but the withdrawals are tax-free, which softens the blow considerably.

Penalty-free withdrawals for a new child

The law added an exception to the 10% early withdrawal penalty for up to $5,000 taken within a year of a child's birth or adoption. Income tax still applies to pre-tax money, but the penalty doesn't, and the amount can be repaid to an IRA later.

This is where federal savers should read the fine print. The exception is clearest for IRAs. Whether a workplace plan offers it is up to the plan, and the TSP's in-service withdrawal options have historically been limited mainly to age-based and financial hardship withdrawals. If you're counting on this provision for TSP money, verify at tsp.gov first.

A few smaller changes worth knowing

The law also allowed tax-free 529 plan withdrawals of up to $10,000 (lifetime) toward qualified student loan repayment, a nod to the debt many younger federal workers carry. It made it easier for employers to offer lifetime income options inside retirement plans. And it made long-term part-time workers eligible for some 401(k) plans, though that mostly affects the private sector rather than the TSP.

What federal savers should take from it

The SECURE Act rewarded people who keep working and keep saving, and it tightened the screws on people who treat an IRA as a multigenerational tax shelter. Three habits make sense in light of it:

  1. Recheck your RMD timing. Know which age applies to you, and remember the rules have changed more than once since 2019.
  2. Review beneficiary designations. The tax math for a spouse, a child, and a trust is now very different. A designation you filed in 2015 may no longer fit your goals.
  3. Plan the drawdown, not just the accumulation. The legislation pushed more attention toward when and how money leaves your accounts, and a coordinated plan across the TSP, IRAs, and your FERS annuity beats improvising at 72.

Contribution limits, RMD ages, and IRS guidance on inherited accounts all change over time. Treat this article as history and context, and confirm current numbers at tsp.gov and irs.gov. For anything involving a large inherited balance or a complicated family situation, an hour with a tax professional costs far less than a bad guess.
