Tax & Accounting released its 2027 income tax projections on Friday, giving tax professionals an early read on the brackets, deductions and AMT levels they will use for planning. The figures arrive before official 2027 rates are published.
The report points to a 3.2% increase in inflation from 2026 and folds that into individual income tax brackets, standard deductions, AMT exemptions and other thresholds. Evan Croen said tax professionals are being asked to make consequential planning decisions amid constant policy change and growing complexity.
Tax and 2027 income
The projections flow directly into Tax's software, including Tax Provision, Tax Fixed Assets and Tax Workpapers. That gives users a path from the rate outlook to the documents and calculations they will actually prepare for clients and internal planning.
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.
OBBBA adjustments in the report
The forecast also reflects several adjustments made under the One Big Beautiful Bill Act, including a change to the threshold for information at source reporting requirements. The threshold was initially increased by the One Big Beautiful Bill Act, so the projection matters less as a headline number than as a planning input for how far those limits may continue to move.
For corporate taxpayers and passthroughs, the report includes an adjustment to the employer-provided child care credit, which the One Big Beautiful Bill Act initially enhanced. That leaves tax teams with a set of projected thresholds they can map against client models before the official 2027 figures arrive.
11-month C-CPI-U average
The projections were calculated using an 11-month C-CPI-U average because the Bureau of Labor Statistics did not report data from October 2025. That missing month makes the release more provisional than a final rate sheet, but it still gives preparers a concrete base for bracket modeling and deduction estimates.
If those projections hold, the lower income tax brackets are set for steeper adjustments than the higher ones, which can change where taxpayers land inside the 2027 bracket structure. Readers tracking the shift can use the forecast now, then compare it with the official 2027 figures once they are released.
