The new AAII 2025–2026 Tax Guide lays out a huge slate of changes: new deductions, shifting MAGI phaseouts, higher retirement contribution limits, expanded senior deductions, SALT cap increases, estate and gift thresholds and dozens of inflation-adjusted rules across investment income, Social Security, Medicare and more.
For many investors, the challenge isn't just knowing the rules-it's keeping track of them.
So I'd love to hear how others approach tax planning now that the landscape is more complicated than ever:
👉 With all the phaseouts, thresholds, MAGI definitions, and new deduction types, how do you stay organized?
Do you rely on a CPA, software like TurboTax, a personal spreadsheet, or some combination?
And on the strategy side:
👉 Which of the new 2025–2026 tax changes do you think will have the biggest impact on your own planning-and why?
Is it the enhanced senior deduction, higher SALT deduction cap, increased IRA/401(k)/HSA limits, QCD threshold changes, or something else entirely?
Curious how other investors are adapting, and if you haven't yet, the full article in AAII's annual Tax Guide is worth a read. It's a comprehensive walk-through of every key number shaping your 2025 and 2026 tax bill.
