Kosher question #1. Every year, I rollover my state income tax refund to be applied to the following tax year. I never declare the refund as income (on 1040 line 10) or as a deduction on schedule A. It's awash. I occasionally get a 1099 (?) from the state, but I ignore it. Yet the IRS has never said anything.
Kosher #2. - Way back in 1972, I started paying alimony. Back then, alimony was a deduction for schedule A. Since then, I've bought a house, so I've never even looked at the standard deduction. Until now. Now, I have no mortgage interest anymore. I just realized that my deductions are not that much more than the standard deduction (including my over-65 bonus). All state withholding is currently optional (from my IRA/401, etc.) or with quarterly payments. I am not employed.
Am I allowed to do this: In late December, 2012, take an extra $15,000 from my IRA. Thence, prepay as much as two years' worth of state income tax. Thence, prepay 2013 real estate tax. Make 2013 charity gifts in 2012. Borrow, if necessary. Take all those deductions on my 2012 federal return. Thence, hold off filing my 2012 state return until January, 2014 so I don't get the refund in 2013. If I play my cards right, I can postpone everything except my automobile excise tax ($400) until 2014. When I file my 2013 federal return, I take the standard deduction.
