When listening to stories from Korean Americans, a common phrase that comes up as they approach retirement is, "I filed my taxes correctly, so why do I feel so insecure about my retirement?"

This feeling of uncertainty is especially pronounced among those who have a high proportion of self-employment or have lived on cash flow while receiving 1099 income.

Unlike employees who have someone handing them 401(k) paperwork or automatically accumulating benefits on their pay stubs, many hardworking individuals find themselves with an empty retirement structure despite their efforts. This isn't a matter of laziness; it's because the American system is structured to benefit only those who take initiative.

The first major oversight is regarding Social Security eligibility and benefits.

In the U.S., Social Security retirement benefits do not just automatically come with age.

Most people need 40 credits, which generally equates to about 10 years of work history, to qualify for retirement benefits. As of 2026, one credit is earned for every $1,890 of covered income, with a maximum of four credits earned per year.

The problem arises when self-employed individuals or 1099 workers report their income too low to reduce taxes or create a net profit that is too low for Social Security to recognize.

The SSA bases its records on the net income reported to the IRS by self-employed individuals, and the monthly benefit amount is calculated based on lifetime earnings records. Therefore, what may have seemed like a good tax-saving strategy in the past can lead to the realization later that, "I worked my whole life, so why is my benefit so low?"

However, it's not too late to take action. If you are already feeling regret, the first thing you should do is check your Social Security earnings record. The SSA advises reviewing your income record through your my Social Security account, and if there are errors, you can request corrections.

Keep in mind that there are generally time limits for correcting income records, so ideally, corrections should be made within three years, three months, and 15 days after the year in question. Therefore, you should not delay. If past records are missing or incorrect, you need to check them immediately rather than saying, "I'll deal with it later." This is not just about retirement preparation; it's more about recovering what has already been lost.

The second mistake is living with the mindset that "I'm not an employee, so retirement accounts don't apply to me." This is quite common.

Many long-time self-employed individuals often think of retirement accounts as products exclusively for salaried employees. However, according to IRS guidelines, there are already systems that self-employed individuals can fully utilize. There is a one-participant 401(k), commonly referred to as a Solo 401(k), and there is also a SEP IRA. The IRS provides separate retirement plan guidance for self-employed individuals, clearly stating that a SEP can be established by self-employed persons. In other words, the statement, "I couldn't do this because I'm the boss," is more about a lack of information than a lack of options.

This aspect should not be dismissed as too late either. Especially for sole proprietors without employees, the IRS explains that they can adopt a section 401(k) plan by the tax filing deadline starting in 2023. Of course, the specifics of salary deferral deadlines, how much can actually be contributed, and which method is most beneficial will vary based on individual circumstances, so calculations need to be done separately.

Still, the important point is this: there's no need to give up just because the year-end has passed. If you feel regret, it's right to compare now which option, Solo 401(k) or SEP IRA, aligns with your income structure. While you can't go back and recover the 20 years you missed, you may still have 5 or 10 years ahead of you.

The third mistake is confusing cash flow with net worth. This is something many self-employed individuals experience.

Money has been coming in every month. The bank account has been active, and the business has been running smoothly. So, there's a sense of, "I'm doing much better than salaried employees." However, retirement isn't based on monthly revenue; it's about the asset structure that continues after you stop working.

Social Security looks at reported earned income records. Self-employed retirement plans must be established by the individual. In other words, the American system pays more attention to "how you recorded your income and what you have accumulated" rather than just "what you are currently earning." If this is overlooked, a business may be operated for a long time, but personal retirement assets may be weak, and the moment the business closes, cash flow may cease as well.

Therefore, for these individuals, the question shouldn't be, "Why didn't you prepare?" but rather, "Let's see where to start fixing this now."

If you have already reported income conservatively, leading to a lower Social Security benefit, you should first verify that your records are accurate.

If you have never opened a retirement account, you need to establish a plan that fits your tax structure this year. If you believed that your business was your retirement plan, it's time to separate the value of the business from personal assets.

In the U.S., those who earn aggressively and those who retire securely are not necessarily the same people. Many perform well in the first half but struggle in the second half. The difference lies not in skill but in structure.

In summary, the common mistakes made by Korean Americans regarding retirement are as follows:

They have underestimated the importance of Social Security credits and lifetime income records, delayed utilizing retirement accounts available to self-employed individuals by thinking, "This doesn't apply to me," and confused the feeling of earning well each month with retirement security.

However, there is a positive aspect to this. All three of these issues can be addressed now, and the structure can be changed, and savings can begin from this point forward.

While past taxes may feel wasted and lost time may be regrettable, if retirement hasn't arrived yet, there is still time to make adjustments.

The real danger lies not in past mistakes but in knowing those mistakes and continuing on the same path this year.
