<prompt> Human: My latest paycheck was higher due to the new withholding tables going into effect. I basically put the extra in savings and paid myself the same amount I was receiving before. I will also be receiving a 3 raise starting with the first paycheck in March. I am wanting to up my retirement and essentially keep paying myself my current salary - however is it safe to do so with the tax changes next year? I want to ensure I dont end up owing.---Extra Info: I am 28, and currently saving 5 in a 401K with a 4 match and currently have 30k in the 401k and 18K in a rollover IRA from my prior cash balance pension both invested in a target date fund.  <response>: Better to put an extra 2,000 in your retirement funds and end up owing the IRS 500 next year than to underfund your retirement and end up getting a 1,000 refund from the IRS next year.
