President Donald Trump has signed the One Big Beautiful Bill into law, delivering what lawmakers describe as the largest tax cut in American history for working- and middle-class families. The legislation makes permanent the key provisions of the 2017 Trump tax cuts, preventing an anticipated $1,700 tax increase on working families and providing an average tax cut of approximately $1,300. It eliminates income taxes on tips for 4 million tipped workers, boosting their incomes by up to $1,300, and removes taxes on overtime pay for over 80 million hourly workers, increasing their earnings by up to $1,400. The bill also extends tax relief to seniors, farmers, and small businesses, including death tax relief for farmers and no tax on auto interest for American-made cars. Additional measures include enhanced Child Tax Credit benefits for 40 million Americans and expanded standard deductions benefiting 91% of taxpayers. Beyond tax cuts, the bill aims to incentivize domestic manufacturing and business investment, secure America's supply chain, invest in border security, promote American energy dominance, reduce government spending, and bolster the military. Lawmakers emphasize that the bill prioritizes American workers and families, putting Main Street before Wall Street, and is expected to stimulate economic growth and rural prosperity. The legislation has received broad Republican support and is presented as fulfilling President Trump's campaign promises to deliver historic tax relief and economic reforms.
