2027 Tax Brackets & Capital Gains Rates: Early IRS Projections

Will Tax Brackets Change in 2027?

The 2027 tax brackets will keep the same seven federal rates while the income ranges around them shift upward. Rates of 10% through 37% are permanent law under the 2025 tax act known as OBBBA. What moves every year is the taxable income attached to each rate, and those cutoffs rise with inflation.

Here is the catch worth understanding before you plan anything. The IRS has not published official 2027 figures yet, and it will not for several months. The last annual revenue procedure, which set every 2026 number, came out on October 9, 2025.

That gap creates a real problem for anyone making year-end decisions right now. Selling a property, timing a bonus, or sizing a Roth conversion all depend on thresholds. None of those thresholds are final yet.

This guide covers what is locked by statute and what inflation will likely move. It also shows how to plan with estimates.

Everything below leans on two sources only: the statute itself and the verified 2026 baseline. No guesswork dressed up as fact. When a number is an estimate, the tables say so in plain language.

A quick note on scope before the details begin. This article covers federal brackets and the federal schedule for gains. State income taxes run on their own adjustment calendars, which we flag where it matters.

How the IRS Builds New Brackets Every Year

Bracket changes are not optional. Section 1(f) of the code forces the issue.

It adjusts dozens of thresholds each year using the Consumer Price Index. The formula divides the average CPI-U for the twelve months ending August 31 by the prior year's average.

Three details inside that formula shape every projection you will see. First, the statute points the IRS at the chained CPI. That variant usually runs a few tenths of a point below headline inflation.

Second, bracket amounts round to the nearest $25. Official thresholds always end in 00, 25, 50, or 75. Third, the standard deduction rounds to the nearest $50 instead.

Since the OBBBA passed in July 2025, the rate structure itself is locked. The law made the seven-rate table permanent, so inflation can no longer push anyone into a higher rate. Your 2027 bracket map will look identical to 2026 in shape, just with wider income bands.

This year carries less legislative noise than usual. Barring a surprise act of Congress, inflation is the only variable left. That makes 2027 one of the cleaner projection years in recent memory.

One more piece matters for capital gains specifically. The three long-term rates (0, 15, 20 percent) are permanent too, and their income breakpoints adjust the same way. That makes the whole 2027 capital gains picture computable today, within the margin of CPI error.

The 2026 Baseline: Ordinary Income Brackets

Every 2027 projection multiplies the official 2026 thresholds by an inflation factor. So the baseline has to be right before anything else matters. The table below lays out the ordinary brackets the IRS published for 2026 in its annual inflation procedure.

Married-separate filers follow the same ordinary brackets as singles. Single filers deduct $16,100 on their 2026 returns, joint filers deduct double that, and household heads land at $24,150. Those deduction amounts matter later, because every capital gains test runs on taxable income.

Want to verify the baseline yourself? The full 2026 inflation adjustments (PDF) live on IRS.gov. Its bracket tables appear in the opening pages.

Every figure in this article traces back to that document. Anything not printed there gets labeled as an estimate on these pages.

The 2026 Capital Gains Breakpoints

Long-term gains follow a separate schedule from the salary brackets above. The 0% rate applies until total taxable income crosses the first ceiling. The 15% rate runs from there to the second ceiling, and 20% applies above it.

These thresholds measure taxable income, not salary, which trips up more filers than almost any other rule. Our full rate breakdown for 2026 covers how gains layer over ordinary income, line by line. Keep these two tables handy, because every 2027 estimate below grows out of them.

One quirk deserves a flag before the projections start. The zero-rate ceiling measures taxable income after gains are included, not before.

That single detail decides who lands the 0% rate. Our worked example later shows exactly how the stacking plays out in practice.

Projected 2027 Income Tax Brackets

Now the estimates. Recent CPI readings give us a working range for the 2027 adjustment factor. The twelve-month CPI-U through August 2026 came in at 3.4%, per the Bureau of Labor Statistics.

The chained version the statute actually uses usually runs slightly cooler. Published estimates account for that gap and land near a 3.2% factor. Apply it to the 2026 baseline with rounding, and the projected brackets look like this.

Treat these as planning estimates, not promises. If inflation runs hot, the top single threshold could reach roughly $662,400. If it cools to 3%, the figure drops closer to $659,850.

The projected standard deduction lands near $16,600 single and $33,250 joint. Head of household lands near $24,900. Each of these figures gets replaced the day the official 2027 release arrives.

The remaining columns follow the same multiplier. Their projected figures appear in the gains table below. Applying the same 3.2% factor and $25 rounding keeps every filing status consistent.

Projected 2027 Capital Gains Thresholds

Long-term investors care most about the 0% ceiling, and the reason is simple. Staying under it means paying nothing on qualified gains. Even a small threshold bump changes real decisions.

The honest range on the single 0% ceiling runs from about $50,925 to $51,125. For joint filers, the band sits between roughly $101,875 and $102,275. Those spreads are narrow enough to plan around but too wide to promise.

Wider ceilings matter most near the boundary. A filer who lands a few hundred dollars over the 2026 limit gains nothing from the 15% rate panic. Waiting until January might keep the entire gain within the zero band instead.

The 20% rate has no threshold to project. It simply applies above the 15% ceiling, so the 2027 shift only moves the entry point for the top rate.

Why the 2027 Factor Could Still Shift

Here is a fact most projection articles skip. The measurement window for the 2027 formula closed on August 31, 2026. The September CPI report released on September 11 filled in the last input, so the raw data already exists.

Why does the IRS still wait until autumn? The chained index publishes slowly and gets revised for about a year after each reading. The agency cannot certify final figures until the series settles.

That revision window is also why serious published estimates land within a few tenths of each other. Outliers you may see usually come from using headline CPI instead of the chained series. Stick with sources that show their method.

The practical takeaway cuts both ways. Estimates published right now should land within roughly half a percent of the official factor. Anyone claiming precision beyond that is overstating what the data supports.

Revisions can nudge the final number after that. The chained series typically drifts a few hundredths of a point between its first and final prints. That drift alone rarely moves a bracket by more than $25.

What the Law Locks in Place for 2027

Several numbers that shape capital gains bills are statutory, meaning inflation adjustments never touch them. Writing these down prevents the most common planning error, which is assuming everything moves. Congress fixed these values in the code itself, and only Congress can change them.

1. NIIT keeps its MAGI triggers at $200,000 single, $250,000 joint. That is the 3.8% levy applied to investment income, net of allowable deductions.
2. Collectibles and section 1202 gains keep a 28% rate ceiling, while unrecaptured section 1250 gain stays at 25%.
3. The section 121 exclusion stays at $250,000 single and $500,000 joint on home sales.
4. The SALT cap climbs by statutory schedule to $40,804 for 2027, with no CPI formula involved.
5. The $6,000 senior bonus deduction and its $75,000 phase-out stay fixed through 2028.
6. The quarterly estimated tax calendar keeps its usual rhythm: the 15th of April, June, September, and January.

Wash-sale timing rules keep their 30-day look-back and look-forward. Gains need just over twelve months of holding before long-term rules kick in. Our 3.8% NIIT walkthrough shows how that levy adds a second layer beyond bracket math.

When the Official 2027 Numbers Arrive

Mark three dates on your planning calendar. October 14, 2026 brings the next monthly CPI report.

Then watch for the official 2027 release in late October or early November. That timeline follows the release pattern of the 2026 set. Retirement account limits usually follow in early November, announced apart from the rest.

Until those documents exist, every 2027 figure you read anywhere is an estimate. Good sources will label projections clearly. The IRS announcement page becomes the single source of truth the moment it updates.

Filing timing helps too. Returns for 2027 are filed in early 2028, leaving months of runway between the release and any real liability. Nobody has to act on a projection tomorrow.

Payroll mechanics follow a different clock. The IRS updates withholding tables each December, which is when 2027 paychecks start reflecting the wider brackets. Planning that waits for January still gets a full year of checks to work with.

Worked Example: Projecting a 2027 Capital Gains Bill

Numbers make this concrete. Meet Sarah and Mike, a married couple whose 2026 taxable income stops at $117,800.

That total blends $87,800 in ordinary income with a $30,000 gain on stock they had held since 2023. That is safely past the long-term holding line.

For 2026, the couple sits $11,100 beneath the $98,900 zero-rate ceiling. So the first $11,100 of gains taxes at 0%. The remaining $18,900 taxes at 15%, a $2,835 federal bill.

Now apply the projected 2027 ceiling of $102,075 to the same real income. The zero-rate band swallows $14,275 of gains, leaving $15,725 for the 15% layer, a $2,359 bill.

The arithmetic is simple enough to check by hand. Take the projected ceiling, subtract the ordinary slice, and the remainder is your zero-rate allowance. Anything beyond that remainder taxes at 15% until the second ceiling arrives.

Same wages, same sale, roughly $476 of federal tax saved through wider brackets alone. That is the practical meaning of inflation adjustment for a patient filer. A single filer in a similar position would see the same pattern against the $51,025 estimate.

Two caveats keep this example honest. State-level tax treats the same sale under separate rules, because state houses adjust on their own calendars. And if this couple's MAGI crossed $250,000, the 3.8% levy would add to every figure shown here.

Run your own situation through the capital gains calculator using both the 2026 and projected figures. The gap tells you whether timing decisions are worth the effort.

Planning Moves You Can Make Before January

Projections become useful when they inform decisions that are hard to reverse later. Five moves stand out for the 2026-to-2027 window. Each one uses the estimates above as guardrails, not guarantees.

1. Fill the projected 0% band while you qualify. If taxable income sits well under $51,025 single or $102,075 joint, selling appreciated shares costs nothing federally. Waiting a full year risks the window closing.

2. Size Roth conversions against the wider 2027 bands. A conversion that barely fits the 22% bracket today may fit with room to spare next year. Our Roth conversion guide weighs the trade-offs.

3. Push flexible income into 2027 when you can. Wider 24% and 32% bands mean a year-end bonus or large invoice costs slightly less in tax. This matters double if 2026 already pushed you against a bracket edge.

4. Set estimated payments from the 2026 baseline, then revisit. Safe harbor rules shield you from underpayment exposure while the official numbers settle. The quarterly estimated payments walkthrough runs through the mechanics.

5. Pair gain timing with loss harvesting where you hold both. Realized losses can absorb gains that overflow a projected ceiling. Our walkthrough on harvesting losses shows how the ordering rules work.

Projection Mistakes That Cost Real Money

Estimates create their own trap doors. Each of these has caught taxpayers in past adjustment seasons.

Treating projections as official tops the list. If you file around a $102,075 ceiling and the real figure lands at $101,875, the difference taxes at 15%. Small amounts, yes, but the same error scales badly at higher incomes.

Second is measuring gross salary against the 0% ceiling. The test uses taxable income once deductions land, with gains riding above the ordinary slice. A filer earning $60,000 in wages may already be near the ceiling once deductions land.

Third, forgetting that NIIT sits outside the bracket system entirely. A projected bracket can look comfortable while the 3.8% levy quietly kicks in past $200,000 of MAGI.

A fourth mistake is assuming your state moves in lockstep with the IRS. Most states levy their regular income rates on gains, on their own adjustment calendars, and some never index at all. California adjusts its brackets every year, while several states still use fixed thresholds.

Watch for mid-year legislation too. Congress can change thresholds outside the normal inflation cycle, as the OBBBA itself did for 2026. A projection written in September deserves a second look before you file.

Selling an asset eleven months into ownership gets short-term treatment even when settlement lands early in 2027. Our holding-period rules guide covers where that boundary sits. Check it before letting a holding period lapse by a week.
