IRS 2027 Tax Brackets: What Your Paycheck Could Look Like

Taxpayers are used to hearing about inflation adjustments every fall, when the IRS releases next year's brackets. But 2027 is quietly becoming a different story, and it could be the most consequential tax year in a decade — long before it arrives. Here's why. The Tax Cuts and Jobs Act, the 2017 law that reshaped nearly every bracket, standard deduction, and credit in the code, expires at the end of 2025. Unless Congress acts, 2026 reverts to pre-2018 rules. That means 2027 is the first full year shaped entirely by whatever lawmakers do — or don't do — in the meantime. So what do the projections actually show? If Congress extends current law, 2027 brackets will look much like today's, just nudged upward for inflation. Analysts expect the 10% rate to start around $12,500 for single filers and roughly $25,000 for married couples filing jointly. The 12% bracket would likely top out near $50,000 single and $100,000 joint, with the 22% tier running into the low six figures. The 24%, 32%, and 35% tiers would all drift higher by roughly 2% to 3% a year, assuming inflation stays near the Fed's target. If Congress does nothing — a scenario Wall Street calls the "sunset cliff" — 2027 looks dramatically different. The bottom rate snaps back to 10% but the next tier jumps to 15%, then 25%, 28%, 33%, and 35%, with a top rate of 39.6%. The standard deduction shrinks by roughly half, the child tax credit drops back to $1,000, and the state and local tax deduction cap disappears entirely. For a family of four earning $110,000, that could mean paying several thousand dollars more. There's a third path gaining buzz: a negotiated middle ground. Some proposals would keep the lower rates but trim the top bracket, phase out the SALT cap at higher incomes, or adjust the child tax credit. Projecting 2027 under that scenario is guesswork, but most estimates land between the two extremes. What should you do with projections that are still two years out? First, don't overhaul your finances based on them. Brackets change, and so do the assumptions behind them. Second, do use them as a nudge. If your income sits near a bracket threshold, accelerating deductions into 2025 and 2026 — while rates are lower — can pay off if 2027 rates rise. Third, max out tax-advantaged accounts now. Roth conversions look far more attractive at today's 22% or 24% rates than at a possible 25% or 28% later. One more thing: state taxes matter more than ever. If the SALT cap vanishes, high-tax states like California, New York, and New Jersey become meaningfully cheaper relative to today. That alone could shift where people choose to retire or relocate. The honest answer is that no one knows what 2027 will bring. The projections are a planning tool, not a prophecy. But the window to act — while today's rules still apply — is open, and it won't stay open forever. **Our take:** Watching 2027 brackets this early feels alarmist, but the expiration date is real and Congress moves slowly. The smartest move isn't panic — it's using the next 18 months to lock in low rates while you still can. If Washington punts, you'll be glad you did; if it acts, you've lost nothing.
