'As a result of this, it is important that Alliant Energy employees understand the basics of Social Security, such as how benefits are calculated and the potential return on delaying the claim, to ensure they are getting the most out of their benefits and thus their overall financial security.'

It is important that Alliant Energy employees be self-initiated with the Social Security laws and regulations because tactics, for example, delaying benefits can result in huge profits in the long run, to the advantage of their retirement plan.

In this article, we will discuss:

1. The Social Security trust fund and more specifically the eligibility criteria for the fund.

2. The significance of cost of living adjustment (COLA) and its implications on the benefits.

3. Ways to optimize Social Security payments by not claiming them.

Social Security has been in effect since 1935 and is one of the most significant sources of income for retired people. We all think we know how it works, but how much do you know? If you work for Alliant Energy, you may be surprised by the following nine facts.

The Social Security trust fund is very large. It is greater than the GDP of every economy except the ten largest: China, the European Union, the United States, India, Japan, Germany, Russia, Indonesia, Brazil, and the United Kingdom. The vast majority of workers, including those working at Alliant Energy companies, are entitled to Social Security discounts. Former federal government employees before 1984 were covered by the Civil Service Retirement System rather than Social Security.

This is because, as a Alliant Energy employee, you do not have to work for long to qualify. Anyone born in 1929 or later must have earned income for at least 10 years to be eligible for benefits. Under the Social Security system, benefits are calculated from the total earnings of an individual's working life. It is based on the 35 years of highest earnings. Social Security may include a person’s low or no earning years in the total number of years for which they are eligible for benefits, up to 35 years.

It is also important for Alliant Energy employees to know that Social Security benefits have not always had cost-of-living adjustments (COLA). Prior to 1975, Congress had to pass a bill to raise benefits; today, automatic revisions are tied to the Consumer Price Index. The COLA in 2026 rose by 2.9 percent, while that of 2026 was 2%. About 67% of current retirees, including Alliant Energy retirees, depend on Social Security as their primary source of retirement income. Social Security benefits were not taxed under federal income tax. The Social Security Act of 1983 modified the Social Security Act to allow for the taxation of benefits from the year 1984. From 1937 to 1940, Social Security payments were made as a one-off lump sum.

A one-off payment was considered to be made to those who had paid into the program. The management of Social Security thought that such people would not work long enough to be eligible for monthly payments. The first Social Security benefit paid in the United States was paid to Earnest Ackerman in January 1937 and was a fixed amount of 17 cents. 1.

Do you know that if you postpone receiving your Social Security benefits past your full retirement age, your monthly benefit amount could increase substantially? This is important for the retirement planning of Alliant Energy employees. Every year that you postpone claiming benefits after your full retirement age, up to age 70, may result in a benefit increase of as much as 8% per year. This means that if you delay claiming, you will receive a higher monthly benefit for the rest of your life. It is therefore advisable to consider this option to ensure that you get the most out of your Social Security payments.

Social Security can be understood as a complex process that is similar to solving a puzzle. This is because for the Alliant Energy employees who are about to retire, it affects their lives. Social Security can be viewed as a large Rubik’s Cube where each of the turns and shifts represents a different fact or provision of the system. To get the benefits you are entitled to, you must know each step of the process. Some of the pieces of the puzzle are interesting and include the fact that the Social Security trust fund is equivalent to the GDP of most countries.

Some of the pieces are strategic and include having to work for at least 10 years to be eligible for benefits. When approaching Social Security as a Alliant Energy employee does, with the patience and determination of a puzzle solver, one can make the right pieces fit together to get the best out of their retirement benefits. Solving a Rubik’s Cube can be time and energy-consuming, but the feeling of a good plan and a secure future is for those who will embrace the challenge.'

Before finalizing any estate plan, it is worth examining how Alliant Energy's employer-sponsored benefits fit into the broader picture. Alliant Energy maintains an active defined benefit pension plan, meaning eligible employees continue to accrue benefits based on years of service and compensation. If you are eligible for a lump sum payout, IRS Section 417(e) segment rates determine how the future annuity stream converts to a present-value payment - rising rates compress the lump sum, so monitoring the plan's stability period and lookback month is critical before you lock in your election date. The choice between a single-life annuity, a joint-and-survivor option, or a lump sum (where available) is generally irrevocable once made, and timing that decision relative to interest rate conditions can meaningfully affect your retirement income picture.

Moving to the healthcare dimension, Alliant Energy provides continued medical coverage to eligible retirees, which can bridge the gap between retirement and Medicare eligibility at age 65 or serve as a supplement to Medicare thereafter. Confirming the service and age requirements for retiree coverage, and understanding your premium contribution, is an important step in building an accurate healthcare cost projection. Coordinating Alliant Energy's retiree coverage with Medicare Part B and Part D enrollment timing can also reduce duplication and avoid late-enrollment penalties. A comprehensive retirement plan that accounts for each element of your Alliant Energy benefits package is the best way to understand what lies ahead.
