<prompt> Human: The briefIncome 63K this yearPretax deduction 4k - includes 1200 healthcare 2800 403b reductionI claim 0s on my W2 and usually get 1500 at the end of the yearCurrent taxes 16,000 and my net is 36K Last year I was heavily putting money into my 403b and put about 15k into my retirement lowering my taxable income and making me feel better about paying less into the 36K tax rate. I have 10k saved up and there is a few paychecks left in the year. I dont need cash for any expenses so my rationale is to put away the next 3 paychecks of 2k straight into retirement to reduce my taxable income at 25 from 36K. That would make it 60k - 4K already deducted, -6k standard deduction - another 6k I can sneak in before the end of the year. Putting me at about 44k taxable income.Am I missing anything? Is the logic sound?Thanks!Edit: My rough calculation saves me about 600 in taxes. 6k put into retirement, means 6k less being taxed at 25 vs 15 10 tax savings on 6k 600  <response>: Ive been doing similar with my remaining paychecks for 2016, not so much to reduce my taxable income, but more to save towards my 401. Latecomer to PFLike others have said, a few things to consider:- Not all companies allow for 100 of your paychecks. Ive seen cap ranging from 50-75, so you should confirm.- Make sure your emergency fund is established 6 month optimally.Im breaking 2nd rule in that my 6 month efund will dip down to 5 month due to my ad hoc decision, but I fully intend to bring it back up beginning of 2017. I feel the temporary loss of 1 month is worth raising my 401 contribution close to cap.
