Standard Deduction for 2027 (Projected)

The IRS has not announced the 2027 standard deduction yet — that typically happens in October or November 2026. The figures below are a ustax.tools trend estimate, built by applying the actual 2025-to-2026 growth rate to the confirmed 2026 base. Clearly labeled PROJECTED throughout; the OBBBA senior bonus deduction is the one exception — it's fixed by statute, so its 2027 amount is already a fact, not an estimate.

2026 (confirmed) vs 2027 (projected) standard deduction

All five filing statuses. The 2026 column is the IRS-confirmed amount; the 2027 column is this page's trend estimate.

Filing status 2026 (confirmed) 2027 (projected) Projected increase
Single $16,100 $16,450 $350
Married filing jointly $32,200 $32,900 $700
Married filing separately $16,100 $16,450 $350
Head of household $24,150 $24,700 $550
Qualifying surviving spouse $32,200 $32,900 $700

2026: IRS Rev. Proc. 2025-32 — confirmed. 2027: ustax.tools trend estimate (2025-to-2026 growth rate of 2.22%, applied to the 2026 base, rounded to the nearest $50) — PROJECTED, not official.

Projected additional standard deduction: age 65+ and blindness

Taxpayers who are 65 or older, or legally blind, add a fixed amount on top of the base standard deduction — one "box" per condition, per person. Single and head of household filers can check up to two boxes; on a married return, EACH spouse independently checks their own boxes.

Single / head of household

Boxes checked 2027 (projected)
65+ OR blind (one box) $2,100
65+ AND blind (two boxes) $4,200

Married filing jointly / qualifying surviving spouse

Boxes checked 2027 (projected)
1 $1,700
2 $3,400
3 $5,100
4 $6,800

Worked example — married couple, both spouses 65+ (projected 2027 figures)

  • Projected 2027 base standard deduction (married filing jointly): $32,900
  • Projected additional amount for spouse 1 (65+): $1,700
  • Projected additional amount for spouse 2 (65+): $1,700
  • Total projected additional standard deduction: $3,400
  • Total projected 2027 standard deduction: $36,300

The OBBBA senior bonus deduction — already known, NOT a projection

Unlike every other figure on this page, the OBBBA senior bonus deduction's 2027 amount is already a settled fact. OBBBA (P.L. 119-21, §70103) fixed it by statute with no inflation-indexing provision, for tax years 2025 through 2028 — so 2027 simply repeats the 2026 amount.

Amount (fixed, 2025-2028)

$6,000 per qualifying person, up to $12,000 if both spouses on a joint return are 65+.

Income phase-out (fixed, 2025-2028)

Reduces proportionally from $75,000 to $175,000 MAGI (single/HoH) or $150,000 to $250,000 MAGI (MFJ).

Run your own numbers on the senior bonus deduction calculator — the 2027 result will be identical to 2026 unless the OBBBA sunset date changes by later legislation.

Methodology — how this page's projection was built

This page does NOT use a third-party forecaster, because none has published 2027 standard-deduction figures as of this writing (2026-08-02) — Bloomberg Tax's and Wolters Kluwer's annual "first look" projections are typically released in September, once more of the year's CPI data is out. Instead, ustax.tools computed a trend estimate: the confirmed 2026 standard deduction grew 2.22% over the confirmed 2025 amount (identical across all five filing statuses, since they scale from the same base); this page applies that same growth rate to the 2026 figures, rounded to the nearest $50 per the IRC §63(c)(4) convention. This is a continuation of a known past trend, not a chained-CPI-U calculation — the real 2027 number depends on inflation data through August 2026 that does not exist yet.

Frequently asked questions

What is the standard deduction for 2027?

Not official yet. This page's projection is ~$16,450 for single filers, ~$32,900 for married filing jointly, ~$16,450 for married filing separately, ~$24,700 for head of household, and ~$32,900 for qualifying surviving spouse — up from the confirmed 2026 amounts. These are a ustax.tools trend estimate (applying the actual 2025-to-2026 growth rate to the 2026 base), not an IRS-published figure. The IRS typically announces the real 2027 amounts around October-November 2026.

Is this page's 2027 standard deduction official?

No — it is explicitly a projection. The methodology: the confirmed 2026 standard deduction grew 2.22% over the confirmed 2025 amount (IRS Rev. Proc. 2024-40 to Rev. Proc. 2025-32); this page applies that same growth rate to the 2026 base, rounded to the nearest $50. That is a trend continuation, not a chained-CPI-U calculation — the real 2027 number depends on inflation data through August 2026 that does not exist yet at the time of writing.

What is the projected standard deduction for married filing jointly in 2027?

~$32,900, up from the confirmed $32,200 in 2026 — a projection, not an announced figure. Qualifying surviving spouse uses the same projected $32,900 amount. If both spouses are 65 or older, add a projected $3,400 more ($1,700 per qualifying spouse) — see the worked example below.

What is the projected additional standard deduction for seniors over 65 in 2027?

A projected $2,100 for a single or head-of-household filer who is 65+, or $1,700 per qualifying spouse on a married return. This "additional standard deduction" is separate from the OBBBA senior bonus deduction below — and unlike the senior bonus deduction, this additional amount IS inflation-indexed each year, so it needs a projection while the senior bonus deduction does not.

Is the OBBBA senior bonus deduction projected too, or already known for 2027?

Already known — no projection needed. OBBBA (P.L. 119-21 §70103, IRC §151(d)(5)) set the senior bonus deduction at a FIXED $6,000 per qualifying person age 65+, with NO inflation-indexing provision, for tax years 2025 through 2028. The 2027 amount is therefore already certain to equal the 2026 amount: $6,000 per person ($12,000 if both spouses on a joint return are 65+), phasing out between $75,000 and $175,000 MAGI (single/HoH) or $150,000 and $250,000 MAGI (MFJ) — those phase-out thresholds are fixed by the same statute and also do not need a projection.

Does OBBBA affect the base standard deduction amount for 2027, beyond inflation indexing?

No structural change is expected for 2027 beyond ordinary annual inflation indexing. OBBBA §70102 made the larger, post-TCJA standard deduction amounts PERMANENT starting 2025 (they were previously scheduled to revert to roughly half their size after 2025 under the original TCJA sunset). That permanence is already baked into both the confirmed 2026 base this page compares against and the 2027 projection above — there is no further OBBBA-driven jump expected for 2027 the way there was for the 2026 tax brackets' lowest two rates (see the 2027 tax brackets reference for that separate, one-time adjustment).

When will the official 2027 standard deduction be announced?

Typically October or November 2026, in the IRS's annual inflation-adjustment revenue procedure (the 2026 figures came from Rev. Proc. 2025-32, released October 9, 2025). This page will be updated with the official figure — and its "projected" framing removed — as soon as that Rev. Proc. is published.
