Bloomberg Tax & Accounting released its projected tax fates for 2027, enabling tax professionals and taxpayers to begin planning for the upcoming year ahead of the official IRS announcement this fall.
The annual Projected U.S. Tax Rates Report indicates a 3.2% increase in inflation from 2026, compared to the 2.7% increase from 2025.
The report “provides early, accurate notice of the potential tax savings that could be realized due to increases in deduction limitations, upward adjustments to tax brackets, and increases to numerous other key thresholds,” Bloomberg Tax & Accounting said Friday.
Because the U.S. Bureau of Labor Statistics didn’t publish a consumer price index report for October 2025 due to a lapse in federal appropriations and the government shutdown, the chained consumer price index (C-CPI-U) was computed on an 11-month average.
The report accounts for several new adjustments made under the One Big Beautiful Bill Act that affect tax planning for taxpayers in 2027 and beyond. For corporate taxpayers and passthroughs, they include an adjustment to the employer-provided child care credit, initially enhanced by the OBBBA. It also includes an adjustment to the threshold for information at source reporting requirements, which was initially increased by the OBBBA. For individuals, the report includes varied income tax rates with steeper adjustments for lower brackets.
“Tax professionals are being asked to make consequential planning decisions amid constant policy change and growing complexity,” Evan Croen, head of Bloomberg Tax & Accounting, said in a statement. “By providing trusted projections before official figures are released and carrying those updates directly into the tools where professionals work, we can help them move from information to action sooner and spend more time applying their expertise to the decisions that matter most.”
The updated rates flow directly into Bloomberg Tax’s software solutions, including Bloomberg Tax Provision, Bloomberg Tax Fixed Assets, and Bloomberg Tax Workpapers.
Other key adjustments, with comparisons of the 2026 amounts and 2027 projections, include:
