UpTrajectory Review
The IRS has released its annual inflation adjustments, raising federal income tax brackets and standard deductions for tax year 2027. The agency revises these thresholds each fall to keep inflation from pushing workers into higher brackets on paper income they never felt. The announcement covers the seven marginal rates, the standard deduction, and dozens of related figures. The IRS publishes the full tables in Revenue Procedure form, and the CNBC piece walks through the headline numbers taxpayers will use when they plan withholding and estimate payments through 2027.
For a small-business owner, this is not a distant policy story. Sole proprietors, S-corp shareholders, and partners pay tax on pass-through income at these individual rates, so every bracket shift changes the real cost of a dollar earned in 2027. The higher standard deduction also matters for owners who take the simple route rather than itemize. Owners who pay themselves a salary from an S-corp should revisit their withholding early in the year, before the new tables settle into paychecks and the chance to adjust fades.
The genuinely new element is the size of the adjustment. Inflation has cooled from its 2022 peak, but the 2027 figures still reflect several years of cumulative price growth, which means a wider band of income taxed at each lower rate. We would urge readers not to treat the headline deduction number as the whole story. The alternative minimum tax exemption, the estate tax threshold, and the contribution limits for retirement plans all move with the same announcement, and those secondary figures often matter more to owners than the bracket table itself.
The effects fall unevenly. W-2 employees will see the change automatically in withholding, which can mask a real tax cut until refund season. Owners who pay quarterly estimates get no such automation; they must recalculate or risk underpayment penalties. High earners in states with their own inflation indexing, or states without it, will see a different combined result from peers across a state line. And owners near a bracket edge should remember that marginal rates apply to slices of income, not the whole pile, a mistake that still drives bad year-end decisions.
Watch two things before January. First, the IRS will post the full Revenue Procedure with every adjusted figure, including the qualified business income deduction thresholds that pass-through owners rely on; read that table, not the summary. Second, Congress could still alter the 2017 tax law provisions scheduled to lapse after 2025, which would interact with these brackets in ways the IRS figures do not reflect. Owners should run 2027 projections with their accountant now, set quarterly estimates from the new tables, and adjust S-corp salaries before the first payroll of the year locks in.
The practical move this week is simple: pull the new bracket table, compare it with your 2026 projected income, and update your estimate worksheet. Ten minutes of arithmetic in December beats a surprise bill the following April.
