TSP Before 59½: The Penalty Rules Federal Employees Get Wrong
Emily A. Hall ·
The 10% early withdrawal penalty applies to retirement plan distributions taken before age 59½. For federal employees there are important exceptions — and one very expensive misunderstanding.
The age-55 rule
If you separate from federal service during or after the calendar year you turn 55, TSP withdrawals are not subject to the 10% penalty. For law enforcement officers, firefighters, and air traffic controllers, the threshold is generally age 50, and under SECURE 2.0 certain public safety employees with 25 years of qualifying service may qualify regardless of age.
The timing is unforgiving in both directions. It is the calendar year of separation that matters, not your exact birthday. Separate at 54 and the exception does not apply — not then, and not when you later turn 55.
The mistake that undoes it
Rolling your TSP into an IRA before 59½ forfeits the age-55 exception. IRAs follow their own rules, and the rule of 55 is not among them.
An employee who separates at 56 and rolls the balance to an IRA the same month converts a penalty-free account into one carrying a 10% surcharge until 59½. If you separated at or after 55 and might need the money before 59½, that is a strong reason to leave it in the TSP.
Disability retirement does not automatically qualify
This is the one that costs people real money.
There is an exception to the penalty for total and permanent disability — but it uses the IRS definition, which is a stricter standard than the one OPM applies when it approves a FERS disability retirement. Being approved for federal disability retirement does not by itself establish that you meet the IRS test.
This has been litigated. In Hollander v. Commissioner (Tax Court Memo 2009-187), a federal employee retired on disability before turning 55, took a TSP distribution, and claimed the disability exception. The IRS disallowed it and the Tax Court agreed.
If you are retiring on disability before 55 and planning to draw on your TSP, get advice from a tax professional first. Do not assume the two disability standards are the same, because they are not.
Other exceptions
Substantially equal periodic payments over life expectancy can avoid the penalty, as can certain other narrow situations. These have technical requirements and unforgiving consequences if broken partway through.
The distinction people conflate
Avoiding the 10% penalty is not the same as avoiding tax. Traditional TSP withdrawals are ordinary taxable income regardless of which exception applies. Qualified Roth TSP withdrawals are treated differently.
Before you take anything out, map the rules against your exact separation age and account type — and verify current rules at tsp.gov, since these details change.
General education, not tax advice. Consult a tax professional before taking a distribution.
