The headline news for the 2025 tax season (filed in 2026) is the “One Big Beautiful Bill Act” (OBBBA) senior deduction, which offers a massive $6,000 additional write-off for qualifying seniors. While this deduction is a financial win, claiming it has introduced a layer of bureaucratic complexity that is catching many DIY filers off guard. Unlike the standard deduction which is automatic, the OBBBA deduction requires affirmative proof of eligibility and a specific calculation of Modified Adjusted Gross Income (MAGI). If you fail to attach the new Schedule 1-A or mismatch your income documents, the IRS system will automatically flag your return for “manual review,” delaying your refund by months. To get your money on time, you must ensure your paperwork packet is perfect before you hit submit.
