A Brief History of Government-Defined Retirement
Most Americans do not save enough for retirement. Over the years, the government has established several tax-advantaged financial models to encourage saving for retirement.
The oldest of these is Social Security, which was introduced in 1935 and is administered by the government itself. It is implemented by employers and by the self-employed. It is mandatory. Employers who do not remit payroll tax on behalf of their employees and self-employed people who do not pay self-employment tax will face stiff penalties. These additional taxes are collected by the government, which then pays benefits to individuals when they become eligible.
Tax-Deferred Plans
The next major governmental push to help Americans save for retirement was the Employee Retirement Income Security Act (ERISA) of 1974. This legislation introduced the tax-deferred model of retirement saving. This type of account is not run by the government, and it is not mandatory.
As the name itself suggests, the money in a tax-deferred account is not permanently spared from taxation; it is taxed later rather than sooner. Contributions to a tax-deferred account are not included in current-year taxable income. Furthermore, investment earnings on the contributions are not included in taxable income in the year they are earned. Rather, both contributions and investment earnings are taxed as a single income source when you withdraw money from the account after you retire.
For tax-deferred accounts, 59½ is the magic age at which you may begin making withdrawals without incurring penalties.
Example: You have $10,000 in taxable earned income. However, if you contribute $1,000 of it to a tax-deferred account, then only the remaining $9,000 is taxable in the current year.
Additionally, unlike a standard brokerage account, you do not need to worry about reporting portfolio income generated within your retirement account as it grows.
Example: You invest $1,000 in a brokerage account.
You buy $500 worth of government bonds and use the other $500 to buy stock in your favorite publicly traded corporation. The bonds pay $20 worth of interest and mature with $4 of original issue discount. The stock pays a $15 dividend. You then sell the stock for $600, resulting in a $100 capital gain.
You now have $139 of taxable income in the form of interest, OID income, dividends, and capital gains, which all need to be reported separately on your tax return.
OR
When you open the brokerage account, you check the box that says “IRA”. This makes the account tax-deferred. You then buy exactly the same stocks and bonds as above that yield $139 of the same types and amounts of income. However, since the account is tax-deferred, none of the earnings are taxable in the current year, and you don’t even need to report any of them.
When you retire and eventually withdraw money from the account, each withdrawal you make will be taxed as ordinary income. You will never have to report how much was earned from stocks vs. bonds, interest vs. dividends, etc.
The logic behind this legislation was that most people will be in their highest tax bracket during their working years and in a lower tax bracket during their retirement years. So it would be to their advantage to defer tax on some of their income and their portfolio earnings until after they retire. So, for many, if not most, people, this story will have a relatively happy ending.
Example: You invest $1,000 in a brokerage account. Over the course of your working years, it grows to a total value of $4,000.
You retire and cash out your retirement account. You now owe tax on the entire $4,000. During your working years, you earned a sizable salary and were consistently in the 22% tax bracket or above. Now that you are retired and living off your retirement earnings and Social Security, you are in the 10% tax bracket. So you pay less than half as much tax on the $4,000 as you would have during your working years.
Qualified Plans vs. Individual Retirement Accounts
ERISA defines two types of tax-deferred accounts, although they both offer the same type of tax advantage. The difference between them is who is responsible for establishing them and how much can be contributed to them.
Qualified plans are implemented by employers and have a relatively high contribution limit. Contribution limits are increased for inflation every year or so. For 2025, the limit for taxpayers under 50 is $23,500. This limit applies to all Qualified plans you participated in within the year.
The term “Qualified plan” may sound a bit vague, but this is the technical term for several types of plans you have undoubtedly heard of. The most familiar is probably the 401(k) plan made available by large private-sector employers. There are similar plans offered by state employers, such as 401(a) and 403(b).
Example: You worked one job early in 2025 and deferred $20,000 of wages to the Qualified plan offered by that employer. Later in the year, you get another job that offers a different qualified plan. Any deferral you make to the second plan beyond $3,500 will be considered an excess contribution and will incur penalties.
Deferrals to Qualified plans are taken out of your paycheck, so people don’t always think of them as “contributions”. And you don’t get to take a tax deduction on them, because the amount of the deferral is left out of the taxable income as reported by your employer. However, while the paperwork is slightly different, the result is the same as if you had included the amount in your taxable income and then deducted it.
Individual Retirement Plans (IRAs) are implemented by the individual taxpayer. IRAs have a much lower contribution limit than Qualified plans. For 2025, the limit for taxpayers under 50 is $7,000. This limit applies to the sum of contributions to all IRAs owned by an individual. Contributions to Qualified plans are subject to a separate limit and so are not considered towards the limit on contributions to IRAs.
Example: You have already maxed out your deferrals to the Qualified plans offered by the employers you worked for during 2025. You may still open an IRA and contribute the maximum of $7,000. Opening a second IRA will not allow you to circumvent this limit on IRA contributions. The limit applies to the total amount of contributions to all your IRAs.
When you contribute to an IRA, you are generally allowed to deduct the amount of your contribution from your taxable income. From a tax perspective, this has the same effect as excluding a deferral from your paycheck.
Another thing Qualified plans and IRAs have in common is that you cannot contribute more than your earned income for the year. So, if you only earned $20,000 during the year, you cannot contribute more than $20,000 to your qualified plan even if the limit is $23,500. Similarly, if you only earned $6,000 during the year, you cannot contribute more than $6,000 to your IRA, even if the limit is $7,000. This earned income contribution limit cannot be circumvented by non-earned income. So, if you win the lottery or make a lot of gains in the stock market, this does not increase your ability to contribute to a Qualified plan or IRA.
For IRAs, but not for Qualified plans, the limits can be combined for married couples. Both spouses can contribute to their respective IRAs up to the limit of their combined earned income. If a couple’s combined earned income is at least $14,000, they can each contribute $7,000. This is true even if only one spouse had earned income.
Required Minimum Distributions
Tax-deferred accounts can generally be inherited and have the same status for heirs as they had for the original owners. Meanwhile, the amount of money in the account continues to grow, and no tax is being paid on it. To reduce the amount of time that money can be rolled forward like this tax-free, the government requires that you begin distributing the money to yourself (and paying tax on it) when you reach a certain age.
This is known as a Required Minimum Distribution (RMD). The rules of RMDs are complex. They generally must be taken starting in the year in which you turn 73. The administrator of your Qualified plan or brokerage for your IRA should contact you before the year is over and tell you the least amount you must withdraw to avoid a penalty.
