In reporting related to FY 2015 tax returns, the IRS reported collecting $3.3t in gross taxes, up from $3.06t in FY 2014.
Collections from businesses, traditionally a smaller component of tax revenues, grew the fastest at just over 10%.
Taxes from individual income made up more than half of what the IRS collected at $1.76 trillion, the highest amount on record, and up 9 percent from the year before. Business income taxes totaled $389.9 billion—the second-highest on record after $395.5 billion in 2007. That accounted for 11.8 percent of all tax collections and increased 10.4 percent from the prior year.
