@Justinmcken while my colleagues @Opus 17 and @VolvoGirl have pointed out different facets of this , I just wanted to point out that the test/ threshold amount i.e. the 25,000, 34,000 etc. are not just SSA amount -- it is the sum of 50% of total SSA plus all other incomes that is tested against the thresholds to determine the taxable portion/amount of SSA income. Thus your other incomes ( i.e. those beside the SSA ) play a significant role in allocating the taxable portion of SSA income.
Hope this clarifies and helps your decision.
