<prompt> Human: Just did my taxes and it is saying I owe 2300. Usually I get back 3-4K. Looks like when I changed jobs last year I incorrectly put 2 exemptions so it was not taking out enough taxes. If I reduce my income on my w-2 by 5-10K it brings my 2300 owed to about a 0-300 refund. Not looking to cheat, but does this mean if I can find 10K in deductions I would bring my amount owed to 0? How do I do that?About my situation, pretty simple: Married filing jointly. Both my spouse and I changed jobs last year so 4 W-2s. 162K combined income. We rent. No investments besides my 401K at my old job. Very small student loan interest and savings account interest. No inheritance, property, etc. We do work from home half the week, the other half were in the office. I bought a car last year for work specifically otherwise use public transportation, get mileage for that job.Any advice appreciated. Really trying to not have to owe anything if possibleAssistant: 5k into a traditional IRA. Im not sure if you meet the AGI requirement, but I personally would rather give my future self 5k than the Feds 5. Human: Can I put it in now, in 2013, and claim it for 2012?  <response>: If you are both covered by retirement plans at work i.e. 401k, you are most likely not going to qualify to take a trad IRA contribution deduction due to your income.If you are using tax software, you can try adding the contributions to see what it says.
