The Most Impactful Tax Changes from the One Big Beautiful Bill Act

As we flip our calendars to August, many of us find ourselves savoring the final stretch of summer by balancing travel, barbecues, and last-minute adventures with family and friends. At our house, we are tackling the remaining items on our summer bucket list and doing our best to squeeze them into an already full calendar. I imagine many can relate, with fall around the corner and the early signs of the holiday season already creeping into store aisles. 

As the season begins to shift, so too does our collective focus. We move from vacations and leisure back to progress and responsibilities. While it may have slipped under the radar amidst summer travels and celebrations, a substantial piece of tax legislation was signed into law on July 4th: the One Big Beautiful Bill Act (OBBBA). Despite its playful name, this bill includes actionable items, which extend key provisions, introduce notable changes, and create new planning opportunities for many Americans. 

Over the coming months, we will explore these updates more deeply in our meetings. However, in the meantime, we have outlined a high-level overview of the most impactful provisions below. Several of these changes are already in effect, while others are slated to begin in 2026 or 2027. As always, we see this as an opportunity to think proactively, using outside-the-box, tailored strategies that align with your broader goals.
