Will TSP stop me from overcontributing?

[domingo3]

Sorry for the silly question. I'm sure the answer is out there, but I must be using the wrong search terms. If elect a high percentage of my pay, will my TSP contributions automatically stop at $17k, or do I have to undershoot by a bit to get as close to $17k without going over? I can only go by whole percentages, but I'd like to completely max out if I'm able. I'm under DFAS if it matters.

Thanks

IIRC the limit is automatically enforced. In my day, of greater concern was the attempt by some to max an individual pay period amount, trying to have zero takehome, as they frontload the year's contributions. In that case the danger is cutting it too close so that the mandatories would not be funded if the contribution amount were honored. In that case the system zeroes the contribution for that pay period, funds the mandatories and surprises the recipient with a big takehome.

divide the 17 k by 26 pay periods i think its 650 ish a pay period. u do not want to tget to the max until your last pay period. nif u get to the max prior, the govt quits giving u the matching funds

Yes, they cut you a check at the end of the year. I did this two years ago and I got my check...which then went to a Roth!
