I like the way you think. The idea of reducing taxes and putting money into IRAs is appealing, but unfortunately, the IRS does not consider income from a pension, military retirement, or other investment income as “taxable compensation” for the purposes of contributing to an IRA or other pretax retirement plan. In the IRS’ view, retirement-account contributions must be “earned income.” Wages, self-employment income, commissions, nontaxable combat pay and even alimony would qualify as earned income, but the fruit of your service does not. I actually have retired clients who work part time in order to allow them to put money away in a Roth or traditional IRA. If a part-time job works for you, then you could contribute to an IRA. Thank you for your decades of military service.
