2021 IRA contribution limits: $6,000 under 50, $7,000 with catch-up
The 2021 contribution limits matched 2020 and 2019. The strategic story was elsewhere: the Build Back Better Act passed the House with provisions that would have killed the backdoor Roth from 2022, the Investment Company Institute reported record Roth conversion volume tied to the 2020 market dislocation, and RMDs resumed after the CARES Act's one-year suspension.

Build Back Better and the near-death of the backdoor
The Build Back Better Act (H.R. 5376) passed the House on 19 November 2021. Its retirement-account provisions would have eliminated the backdoor Roth IRA starting in 2022 by prohibiting Roth conversions of after-tax money in IRAs and 401(k) plans. It would have eliminated the mega backdoor Roth for high earners by prohibiting in-plan conversions of after-tax 401(k) contributions. It would also have capped high-balance retirement accounts at $10 million for incomes above $400K single or $450K MFJ and forced accelerated distributions above that cap.
None of these provisions became law. The Senate did not pass H.R. 5376 in its original form. The Inflation Reduction Act of August 2022, which became the eventual successor, dropped all of the retirement-account restrictions. Backdoor Roth, mega backdoor Roth, and uncapped IRA balances all remained legal. As of the 2026 tax year they are still legal and continue to be widely used. The brief window of legislative risk in late 2021 did, however, cause a measurable spike in 2021 Roth conversion activity as filers raced to lock in conversions before the proposed 2022 cutoff. See H.R. 5376 (Build Back Better).
The Investment Company Institute's annual retirement statistics showed total IRA assets reaching new highs through 2021. Roth IRA assets in particular grew faster than Traditional IRA assets that year, partly from conversions and partly from the asset-price recovery from the March 2020 lows. For 2026 readers tracking the long arc, 2021 is when the Roth-first default went mainstream in advisor recommendations.
Markets returned roughly 28% on the S&P 500 in 2021. A $6,000 Roth contribution made early in the 2021 calendar year and left invested through end-2025 grew at well above average rates. Anyone who used the 2021 contribution window has captured five years of strong returns inside the Roth wrapper.
What changed from 2020
- Base and catch-up limits unchanged ($6,000 + $1,000).
- RMDs resumed (CARES suspension was one-year only).
- Roth phase-outs nudged up: single from $124K-$139K to $125K-$140K, MFJ from $196K-$206K to $198K-$208K.
- Build Back Better passed House with backdoor-Roth elimination provisions; Senate did not act.
- Coronavirus-Related Distributions no longer available; 2020 was the only eligible year.
- Deadline was 18 April 2022 because 15 April fell on the DC Emancipation Day weekend.
FAQ
What were the 2021 IRA contribution limits?
$6,000 under 50, $7,000 with the $1,000 catch-up if 50 or older. Combined across all of your IRAs.
Did Build Back Better kill the backdoor Roth?
No. The bill passed the House in November 2021 with provisions that would have killed it from 2022 onward but the Senate did not pass that version. The eventual Inflation Reduction Act of August 2022 dropped the retirement-account restrictions entirely. The backdoor Roth remained legal in 2022 and continues to be legal in 2026.
Were 2021 RMDs required?
Yes. CARES Act §2203 suspended RMDs only for 2020. RMDs resumed for tax year 2021.
When was the 2021 IRA contribution deadline?
18 April 2022, because the normal 15 April deadline fell on the Friday of Emancipation Day weekend in Washington DC. The deadline has passed.
What was happening to retirement-account legislation in 2021?
The Senate Finance Committee was working on what would become SECURE 2.0, which finally passed in December 2022. Build Back Better in late 2021 was a separate House bill with retirement provisions that did not survive Senate negotiations.
Did 2021 have unusual Roth conversion activity?
Yes. ICI data and IRS Statistics of Income suggest 2021 had elevated conversion volume, driven partly by the threat of Build Back Better cutting off the backdoor in 2022 and partly by 2020 conversions completed at low valuations being followed by complementary 2021 conversions.
