NOTE 14: INCOME TAXES

As a real estate investment trust (REIT), we generally are not subject to federal corporate income taxes on REIT taxable income that is distributed to shareholders. We are required to pay corporate income taxes on earnings of our Taxable REIT Subsidiaries (TRSs), which include our Wood Products segment and a portion of our Timberlands and Real Estate & ENR segments.

The quarterly provision for income taxes is based on our current estimate of the annual effective tax rate and is adjusted for discrete taxable events that have occurred during the year. Our 2025 estimated annual effective tax rate, excluding discrete items, differs from the U.S. federal statutory tax rate of 21 percent primarily due to state and foreign income taxes and tax benefits associated with our nontaxable REIT earnings.

Tax Legislation

On July 4, 2025, H.R. 1, commonly known as the One Big, Beautiful Bill Act (the OBBBA), was enacted. The OBBBA contains significant changes to corporate taxation, including accelerated deductions for capital spending, expensing of research and development costs and increased deductibility of interest expense. Additionally, effective for taxable years beginning after December 31, 2025, the value of TRS securities that a REIT may hold will increase from 20 percent to 25 percent of the value of the REIT’s total assets. We do not expect a material impact to our financial statements due to the enactment of the OBBBA.
