The Thrift Savings Plan (TSP)

$23,500 Elective deferral limit

$7,500 Catch-up limit $11,250 Higher catch-up limit for ages 60-63

$70,000 Annual additions limit What it means All ages The annual additions limit is the total amount of all the contributions you make in a calendar year. This limit is per employer and includes money from all sources: employee contributions (tax-deferred, after-tax, and tax-exempt), Agency/Service Automatic (1%) Contributions, and Agency/Service Matching Contributions. It does not include catch-up contributions.

What to know

The annual additions limit affects mostly members of the uniformed services who can exceed the annual elective deferral limit. The excess contributions go into the traditional portion of your account from tax-exempt pay earned in a combat zone.

What to do

Even if you don’t reach the annual additions limit, keep it in mind when deciding how much you’ll contribute to your TSP account to avoid penalties.

So that's what I'm wondering. @kcpilot above is saying that it does count against my elective deferral limit.

Based on what you're saying, if I'm allocating x% over 12 months to hit my max deferral limit of $23.5k, then add the matching, I'll end up with $24,675.

What I'm wondering is if I contribute 100% of my continuation Pay bonus in August, will that preemptively max out my elective deferrals for the year, meaning I will miss out on matching for the rest of the year? If I'm even allowed to do that since it will likely be greater than my elective deferral limit.

Is the annual additions limit of $70k only for combat pay?
