H&W both retired in June of 2014 and both were participants in employer retirement plans, actually 403Bs, as they are both teachers. Their wages were $73,9873 state tax refund of $11, teacher’s pensions of $22,608 and taxable socsec of $13,926, a $292 educator expense deduction, a TIRA deduction of $3600.00. Knowing that the MFJ full deductibility limits for a ’14 TIRA, both being participants in an employer plan is MAGI below $96K, partial up to $166K. The IRS has an MAGI computation table that takes AGI, which for them is $106781 adds back the IRA contribution and subtracts the taxable social security. If this is correct then the MAGI is $96455. First question is–Is this the correct way to calculate this? Second question–if it is correct, how does the limit on deductibility work? For example if only $455 is over the limit and $455 is 2.3% of $20K is 87.7% deductible? TY
