I want to make sure that there is not a software glitch in Turbo Tax calculating the taxable amount of my Social Security benefit income. My Married Filing Jointly income in both 2023 and 2024 was over the $44K threshold, (and our 2024 Social Security benefits are slightly more than in 2023), but the taxable amount on the Social Security income is much less in 2024 than it was in 2023. It sounds good but I'm trying to understand how that can be correct. What else, if anything, factors into the amount of SS income that is taxable? I calculated Combined Income (AGI + nontaxable interest + half of SS benefits) and compared it from 2023 to 2024, and I do see that our combined income is less in 2024 than it was in 2023. Is there information somewhere that shows fine tuning on calculation of taxable SS benefit income - something beyond just either above or below the 44K threshold?
