The American tax code is currently undergoing significant changes due to multiple pieces of legislation. While much of the public discourse has focused on the new tax cuts and deductions, a lesser-known change embedded in the SECURE Act 2.0 could have profound implications for a specific group of investors and savers.
This particular rule alters the way seniors can make catch-up contributions to their retirement accounts. For individuals above a certain age and income threshold, these modifications could have a significant impact on their long-term savings and investment strategies.
Signed into law by President Joe Biden at the end of 2022, the SECURE Act 2.0 aims to incentivize individuals to build a larger retirement nest egg. It includes substantial changes to various retirement savings plans such as 401(k), IRA, Roth, and others, expanding coverage and providing more flexibility.
One of the most notable changes introduced by the SECURE Act 2.0 is the introduction of a “super catch-up” contribution limit for seniors. Individuals between the ages of 60 and 63 will be able to make an additional $11,250 contribution to their 401(k) starting in 2025. Additionally, those over the age of 50 can make an extra $8,000 in catch-up contributions in 2026, as per the IRS.
However, the law also imposes a new income-based restriction on catch-up contributions. Starting in 2026, individuals over the age of 50 earning more than $145,000 must allocate their catch-up contributions to a Roth 401(k) instead of a traditional 401(k). While this may seem like a minor technicality, it can result in higher upfront tax payments for high-income seniors.
Contributions to a Roth 401(k) are made on an after-tax basis, meaning that individuals no longer receive the tax deduction associated with traditional 401(k) contributions. Consequently, a 60-year-old earning $192,000 making a super catch-up contribution of $11,250 could face nearly $3,600 in taxes if their marginal tax rate is 32%.
If you believe these changes may affect you, it is essential to act promptly to minimize your tax liability. Estimating your income for the upcoming year and ensuring your employer offers a Roth 401(k) plan are crucial steps. Consulting with a tax advisor or financial planner to adjust your long-term savings and investment strategies may also be beneficial.
Ultimately, the changes introduced by the SECURE Act 2.0 mean that individuals above a certain age and income threshold may face higher tax obligations in the coming year but potentially lower tax liabilities in the future. Adjusting your retirement plan accordingly in light of these new regulations is vital for securing your financial future.
