The Roth IRA’s general base contribution limit has increased eight times since contributions began in 1998: nine distinct amounts, from $2,000 to $7,500 for 2026. Congress scheduled the 2002, 2005 and 2008 increases; inflation indexing applies after 2008 under IRC §219(b)(5). The separate age-50 catch-up is $1,100 for 2026, making the general age-50+ cap $8,600. These are shared Traditional/Roth IRA limits, subject to compensation and Roth income eligibility.
Quick Facts
- infoOriginal cap (1998): $2,000, no indexing, no catch-up — held flat for 4 years.
- check_circleCurrent cap (2026): $7,500 base, $8,600 with the 50+ catch-up.
- infoTwo legislative drivers: EGTRRA scheduled increases (2002-2008) followed by IRC §219(b)(5) COLA indexing (2009-present).
- infoCatch-up indexing began in 2024; the first increase was in 2026. SECURE 2.0 §108 added the adjustment, rounded down in $100 increments.
- warningThe $0–$10,000 MFS phase-out is not indexed. It applies when a married-filing-separately taxpayer lived with their spouse at any time during the tax year; living apart all year changes the applicable range.
The Three-Phase History
The Roth IRA was enacted in 1997, with contributions available for tax years beginning after December 31, 1997. Its general contribution limits fall into three phases:
- Phase 1: Original cap (1998-2001). The Taxpayer Relief Act of 1997 (P.L. 105-34), §302, created IRC §408A and tied Roth contributions to the existing $2,000 IRA cap, reduced by other regular IRA contributions. There was no general age-50 catch-up or automatic inflation adjustment. The cap stayed flat for four tax years.
- Phase 2: EGTRRA scheduled increases (2002-2008). The Economic Growth and Tax Relief Reconciliation Act of 2001 (P.L. 107-16), §601, set the base at $3,000 for 2002–2004, $4,000 for 2005–2007, and $5,000 for 2008. It also introduced an age-50+ catch-up: $500 for 2002–2005, then $1,000 beginning in 2006. Enactment in 2001, scheduled increases starting in 2002, and inflation indexing after 2008 are different dates.
- Phase 3: Inflation indexing (2009-present). IRC §219(b)(5)(C) adjusts the statutory $5,000 base using its specified inflation reference period, then rounds down to a $500 multiple. The first resulting base-limit increase was in 2013. A year can have an inflation adjustment without a higher published limit; the rule also does not guarantee that any increase will be exactly $500.
Year-by-Year Contribution Limits
All figures are nominal dollars and show the general regular-contribution cap, not every historical special-relief provision. Catch-up applies if you are 50 or older by year-end; Total (50+) = base + catch-up. A row groups years with the same base and catch-up amounts. The 2006 change affected only the catch-up.
Not a separate allowance for each account: the cap is shared across your Traditional and Roth IRAs. Your regular contributions also require sufficient qualifying compensation, including the joint-return spousal-IRA rules, and direct Roth contributions are subject to the income phase-outs below. Roth conversions do not use this regular-contribution cap. Employer SEP contributions and SIMPLE-plan contributions have separate rules; this table does not set those limits. A permitted Traditional IRA contribution is not necessarily deductible.
| Years | Base limit | Catch-up (50+) | Total (50+) | Authority / context |
|---|---|---|---|---|
| 1998-2001 | $2,000 | — | $2,000 | TRA-97 §302 (P.L. 105-34) — created the Roth IRA |
| 2002-2004 | $3,000 | $500 | $3,500 | EGTRRA §601 (P.L. 107-16) — first scheduled increase + first catch-up |
| 2005 | $4,000 | $500 | $4,500 | EGTRRA §601 scheduled step |
| 2006-2007 | $4,000 | $1,000 | $5,000 | EGTRRA §601 scheduled catch-up doubling |
| 2008-2012 | $5,000 | $1,000 | $6,000 | EGTRRA §601 final scheduled step; held flat 5 yrs (rounding) |
| 2013-2018 | $5,500 | $1,000 | $6,500 | First indexed base increase in 2013; IRS historical COLA table |
| 2019-2022 | $6,000 | $1,000 | $7,000 | Notice 2018-83 raised the 2019 base; unchanged through 2022 |
| 2023 | $6,500 | $1,000 | $7,500 | Notice 2022-55 |
| 2024-2025 | $7,000 | $1,000 | $8,000 | Notice 2023-75 (2024) and Notice 2024-80 (2025); catch-up indexing began in 2024 without an immediate increase |
| 2026 | $7,500 | $1,100 | $8,600 | Notice 2025-67; first indexed IRA catch-up increase |
The table covers 29 tax years, 1998 through 2026 inclusive, with nine base-limit amounts and eight increases: 2002, 2005, 2008, 2013, 2019, 2023, 2024 and 2026. The first three increases were scheduled in statute; the last five resulted from indexing. The IRS also lists the historical bands in Publication 17 (2025), chapter 9, the contribution-limit table under excess contributions.
Catch-Up Contribution History
The age-50+ catch-up was created by EGTRRA §601 effective 2002. Four periods distinguish changes in the amount from changes in the indexing rule:
- 2002-2005: $500 — initial catch-up amount under EGTRRA.
- 2006-2023: $1,000 — EGTRRA’s scheduled doubling. Held flat for 18 years through statutory text alone (no automatic indexing).
- 2024-2025: $1,000 — SECURE 2.0 §108 added indexing effective tax year 2024, but the $100 rounding rule meant no change for those two years.
- 2026: $1,100 — first indexed increase per IRS Notice 2025-67. Later years require their own annual adjustment; $1,100 is not a permanent amount.
Using BLS annual-average CPI-U (U.S. city average, all items, not seasonally adjusted), $1,000 in 2023 had about $662 of 2006 purchasing power: $1,000 × 201.6 ÷ 304.702. That is a loss of about 34%, not 50%. This purchasing-power illustration is separate from the statutory indexing formula. SECURE 2.0, Division T, §108, added catch-up indexing for tax years after 2023 using a 2022 reference year, not 2002.
MAGI Phase-Out Evolution
The Roth IRA contribution limit phases out above certain MAGI (modified adjusted gross income) thresholds. The 1998 origin thresholds were:
- Single/HoH: $95,000-$110,000 (full to zero)
- MFJ: $150,000-$160,000 (full to zero)
- MFS: $0-$10,000 if the spouses lived together at any time during the tax year
For 2026, IRS Notice 2025-67, pages 4–5, gives these ranges:
- Single/HoH: $153,000-$168,000 (1.6× the 1998 lower threshold)
- MFJ / qualifying surviving spouse: $242,000-$252,000 (about 1.6× the 1998 joint lower threshold)
- MFS, lived with spouse at any time during the year: $0-$10,000 (not indexed)
A married-filing-separately taxpayer who lived apart from their spouse for the entire year uses the single/HoH range. These are limits on direct Roth contributions, not income limits on Roth conversions. See Publication 590-A, Roth IRA contribution limits and conversion rules.
The phase-out widths remain $15,000 for single/HoH and $10,000 for joint filers. Under IRC §408A(c)(3)(D), the single/joint starting thresholds have been indexed since 2007, using a 2005 reference year and rounding the increase to the nearest $1,000. That differs from the base contribution cap’s reference year and $500 round-down rule. Current eligibility and phase-out details · MAGI estimator tool · year-by-year MAGI phase-out history.
Real-Dollar Comparison: 1998 vs 2025
This comparison ends in 2025, not 2026. The full-year 2026 CPI average is not yet available as of September 29, 2026. The BLS CPI-U table reports annual averages of 163.0 for 1998 and 321.943 for 2025 (U.S. city average, all items, not seasonally adjusted; 1982–84 = 100). We use BLS’s published 2025 average, which reflects the available data; October was unavailable.
The original $2,000 cap equals about $3,950 in 2025 dollars: $2,000 × 321.943 ÷ 163.0 = $3,950.22. The 2025 base cap of $7,000 was therefore about 1.77× that inflation-adjusted starting cap; the $8,000 age-50+ total was about 2.03×. No catch-up existed in 1998. The base-only comparison excludes catch-up contributions; it cannot be explained by their introduction.
For a separate nominal comparison, the 2026 $7,500 base is 3.75× the original $2,000, and the $8,600 age-50+ total is 4.30×. Those two ratios do not adjust for inflation and do not describe investment returns.
Why the Limit Holds Flat in Some Years
IRC §219(b)(5)(C) adjusts the statutory $5,000 base using the §1(f)(3) cost-of-living adjustment with its specified 2007 reference year, then rounds the result down to a $500 multiple. It does not restart the inflation calculation from the year of the last increase. That rounding helps explain why the base:
- Held flat at $5,000 from 2008-2012 (5 years)
- Held flat at $5,500 from 2013-2018 (6 years)
- Held flat at $6,000 from 2019-2022 (4 years)
- Held flat at $7,000 from 2024-2025 (2 years)
The catch-up separately adjusts $1,000 using a 2022 reference year and rounds down to a $100 multiple. It remained $1,000 in 2024 and 2025 before increasing to $1,100 in 2026. A hypothetical indexed base value of $7,499 would round down to $7,000; $7,500 would remain $7,500. A hypothetical indexed catch-up of $1,099 would round down to $1,000; $1,100 would remain $1,100. These illustrate rounding, not IRS estimates for a future year.
The current §1(f)(3)–(6) method uses chained CPI-U (C-CPI-U), with a statutory transition calculation for reference years before 2017. Its annual measurement uses the 12-month period ending August 31 of the preceding year; it is not a December-to-December inflation rate or the latest monthly headline CPI reading. The CPI-U purchasing-power illustration above is a different calculation.
The Future: 2027 and Beyond
2027 amounts are not included in this historical table. As of September 29, 2026, the IRS retirement-limit reference lists 2026 as its latest year. We have removed numerical forecasts; use the published IRS limits for the relevant tax year, not an extrapolation from the previous rounded cap.
Sources and Measurement Notes
- Enactment and scheduled amounts: P.L. 105-34 §302 (enacted August 5, 1997; Roth provisions effective for tax years after 1997); P.L. 107-16 §601 (enacted June 7, 2001; scheduled increases starting in 2002 and base indexing after 2008). The links in the history section go to the enacted texts.
- Historical amounts: IRS Publication 17 (2025), chapter 9, and the IRS historical COLA table, §219(b)(5)(A)/(B) rows. The latter supports the 2002–2025 amounts; its blank 1998–2001 entries are not treated as zero limits.
- Annual notices: Notice 2018-83, page 3 (2019 base increase); Notice 2022-55, page 3 (2023); Notice 2023-75, page 3 (2024); Notice 2024-80, page 4 (2025); Notice 2025-67, pages 4–5 (2026 caps and income ranges). A notice’s issue year is not necessarily its applicable tax year.
- Current eligibility and indexing: IRC §219(b)(1), (b)(5) and (c); §408A(c)(2), (3) and (5); §1(f)(3)–(6); SECURE 2.0 §108 (enacted December 29, 2022; effective after 2023). IRS Publication 590-A (2025) supplies explanatory contribution and conversion rules; Notice 2025-67 supplies the 2026 amounts.
- Purchasing power: BLS CPI-U annual averages for the stated observation years. Data checked September 29, 2026. This is not the statutory chained-CPI limit calculation or a forecast of full-year 2026 inflation.
Corrections and updates
September 29, 2026 — Correction: The page previously described nine base-limit changes; there are nine distinct base amounts and eight increases across 29 tax years, 1998–2026. Base indexing applies after 2008, not starting in 2002. Corrected the fixed inflation reference years, round-down rules and distinction between CPI-U and the statutory chained-CPI method; the catch-up reference year is 2022, not 2002. Replaced incorrect historical source references while retaining the verified cap amounts. Added the shared Traditional/Roth cap, compensation and filing-status conditions. Recalculated the 2006–2023 catch-up purchasing-power loss as about 34%, not 50%, and replaced the unsupported full-year 2026 comparison with a sourced 1998–2025 comparison. Removed numerical 2027 forecasts and unsupported explanations of legislative intent.
