IRA Contributions:
The maximum deduction is $5,500 per spouse if NEITHER is an active participant in an employer-sponsored retirement plan.
There are rules to this: Their combined EARNED income has to be at least the amount contributed.
If an individual is an active participant in an employer-sponsored retirement plan then there are phaseouts. Wiley has 2013 info and the phaseout for an individual was AGI between $59K-$69K and married $95K-$115K. The phaseout is higher if one spouse is active and the other isn't. The calculation is the difference between the AGI and the start of the phaseout/$10K or $20K if married. Then multiply that by the difference you first calculated. We had an example many pages ago where the couple made $185,000 AGI and the start of the phase out was $181,000. So the calculation of the phaseout was $4K-($4K/$20K)=$3,200. I know this is confusing, but just remember that there is not a good likelihood that the phaseouts will be on the test so don't memorize them. If they give you a phaseout in the problem, know how to use it.
