Looking for information on the "Big Beautiful Bill"?

The Big Beautiful Bill—officially the One Big Beautiful Bill Act—was passed by Congress in July 2025 as a major tax and economic reform package. Its goal is to reduce taxes for individuals and families, increase take‑home pay, and streamline several federal tax rules.

This new law introduces several high‑impact deductions, including no tax on tips, no tax on overtime, and additional relief for seniors. These provisions are designed to lower taxable income for millions of Americans and provide meaningful financial relief throughout the 2025–2028 filing years.
