This is a small victory, but I find the bragging on this forum topic to be inspiring.
I got a step increase in pay this month so I increased my 457b contribution to put all the new pay into pre-tax retirement savings. While doing it I noticed I was having income tax taken out of each paycheck, but paid no income tax last year, so I adjusted my income tax withdrawal to 0 and increased my 457b contribution by that amount as well.
Increase is modest, $375/paycheck to $455, but is a step closer to reaching the max!
