After-tax contribution is contribution to a Roth IRA account, which anyone can make if they meet the income threshold. Unlike a 401(k) plan, which primarily uses pre-tax dollars out of your paycheck for contributions, an individual has the benefit of using after-tax dollars for a Roth IRA.

A Roth IRA account has many benefits, especially for those preparing for retirement. Because the contributions to a Roth are made from after-tax dollars, the withdrawals are tax-free after retirement. This can be more beneficial than a traditional 401(k) plan, which uses pre-tax dollars for contributions and is subject to taxes after withdrawal.

The annual contribution maximum for a Roth IRA account in 2022 is $6,000 per year for those under age 50 ($6,500 for 2023). However, there are some income threshold requirements that must be met in order to be eligible to contribute to a Roth IRA. For example, single filers with a modified adjusted gross income of less than $139,000 (or $206,000 for married filing jointly) may be able to contribute the maximum amount.

Another benefit of a Roth IRA is the potential to earn more money. Because contributions are made with after-tax dollars, investments within the account have the potential to grow over time. This can result in more money at retirement since all of the gains are remained untaxed.

Making after-tax contributions to a Roth IRA is an attractive option for many who are looking to save for retirement. It allows individuals to save money that would otherwise be taxed, resulting in more money to enjoy during retirement. Furthermore, Roth IRA accounts have the potential to earn more than a traditional 401(k) plan due to the tax-free nature of the withdrawals. Therefore, making an after-tax contribution to a Roth IRA can be a smart decision for someone looking to maximize their retirement savings.
