With the sale of a client’s primary residence, many tax professionals are familiar with the Section 121 exclusion, which allows taxpayers to exclude up to $500,000 ($250,000 for single - $500,000 for married filing jointly) on capital gains for the sale. Often, the only criteria mentioned is that the taxpayer must have owned and occupied the home for two of the most recent five years. However, this barely scratches the surface of Section 121; there’s much more money-saving potential in this portion of the tax code.
Year-End Tax Planning Under the One Big Beautiful Bill Act (OBBBA)
Dominique Molina, CPA MST CTS
The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, doesn’t reinvent the tax code it refines it. Much like its predecessor, the Tax Cuts and Jobs Act (TCJA), it keeps many familiar provisions in play: lower rates, expanded SALT flexibility, and broader deductions. But here’s the real story: While most tax pros are busy memorizing what stayed the same, the planners who will win 2025 are the ones spotting what just became possible. OBBBA quietly opens a handful of powerful new planning windows — each one capable of delivering real, measurable savings for the right client. The key is knowing which changes are worth your time… and which are just political garnish. Below, we’ve curated the most strategic, high-impact moves to make before year-end 2025, the ones that separate the advisors who explain the law from those who leverage it. Most tax pros will stop at what changed. The smart ones will keep reading to learn how to use it.
