Warren Buffett's Berkshire Hathaway is now responsible for a staggering 5% of all corporate income taxes paid in the U.S., according to recent reports. That’s a jaw-dropping figure for a single company—especially one that’s not a tech giant or oil major. It highlights just how massive Berkshire’s empire has become, spanning insurance, railroads, energy, and more.

Editor’s Note: This isn’t just a fun fact—it’s a snapshot of how corporate power and tax burdens are concentrated in a handful of mega-firms. While some might see it as a sign of Berkshire’s success, others could argue it underscores how few companies shoulder the lion’s share of U.S. tax revenue. Either way, it’s a reminder of how uneven the playing field can be in big business.
