Seven Factors That Can Reduce Your Social Security Benefits

You probably already know that your Social Security benefit is based on several factors unique to you, including your earnings history and your age at sign-up. As a result, it can be challenging to know exactly how much you will receive from the program before applying.

Many hope their benefits will adequately supplement personal savings, allowing for a comfortable retirement. However, certain variables can lead to a payout that’s lower than expected. Below are seven key factors to consider.

1. A Short Work History

To qualify for Social Security retirement benefits, you must earn a minimum of 40 work credits. As of 2025, one credit equals $1,810 in earnings, and you can earn a maximum of four credits per year. If you have fewer than 40 credits, you will not qualify for benefits, although you may still receive spousal benefits based on your spouse’s work record.

Working at least 10 years and earning enough to secure maximum credits typically qualifies you for some benefits during retirement. Nevertheless, expect lower payouts if you have a shorter work history. The government calculates your benefit from your average monthly earnings over your 35 highest-earning years. Fewer working years can result in zero-earnings years in your benefit calculation, leading to smaller checks. Aim to work at least 35 years before claiming benefits if possible.

2. Low (or High) Lifetime Earnings

Your Social Security benefit directly correlates to your earnings history. Higher earners typically receive more substantial benefits, while those with lower earnings may find their checks smaller than anticipated.

Interestingly, high earners may be surprised to learn that their benefits could also be lower than expected. This discrepancy is often due to the Social Security taxable wage base, which limits the amount of earnings subject to Social Security payroll taxes. For 2025, this limit is set at $176,100. Any income exceeding this amount is not subject to Social Security tax and therefore does not factor into your monthly benefits in retirement.

3. Claiming Early

Applying for Social Security benefits before reaching your full retirement age (FRA)—67 for most workers currently—results in a penalty. Beneficiaries lose 5/9 of 1% for each month claimed early for up to 36 months, and 5/12 of 1% for each additional month thereafter. For instance, if you claim benefits at 62, you’d reduce your payout by about 30%. However, claiming early may be a reasonable option if you do not anticipate a long life or cannot cover your expenses otherwise.

If you’re working while claiming Social Security before reaching FRA, keep an eye on the earnings limit. The government deducts $1 from your total benefit for every $2 earned over $23,400. If you reach FRA within the year but earn over $62,160 before your birthday, the deduction drops to $1 for every $3 earned. Thankfully, amounts withheld due to this earnings test may be recovered as permanent benefit increases once you reach the FRA.

4. Owing Certain Debts

While most creditors cannot garnish your Social Security checks, exceptions exist. If you’re in debt to the federal government, such as having unpaid taxes, the government can withhold up to 15% of your checks until the debt is settled.

Additionally, the Social Security Administration can garnish benefits for unpaid child support or alimony, withholding between 50% to 65% of your checks for these obligations.

5. Changes to Your Marital Status

If you are claiming spousal benefits and get divorced, you may lose the ability to claim on your ex’s work record, provided you were married for less than ten years. However, you can still claim benefits based on your own work history.

Moreover, remarriage can impact benefit eligibility. If you remarry and wish to claim spousal benefits on an ex-spouse’s record, you lose that option but can claim benefits on your new partner’s record if they are claiming retirement benefits.

6. Being on Medicare

For individuals receiving Social Security benefits and enrolled in Medicare, premiums for Medicare Part B are typically withheld from your Social Security checks. In 2025, these premiums are priced at $185 per month.

While you can choose to pay these premiums differently, automatic withdrawal is a popular choice among seniors, simplifying bill management.

7. Income Taxes on Social Security Benefits

Taxes on Social Security benefits do not directly reduce the monthly checks you receive; however, they can impact the amount you ultimately keep. If your benefits are taxable, you may face an unexpected bill when filing your tax return.

Planning ahead by saving for potential taxes is wise. Alternatively, you can request the Social Security Administration to withhold a portion of your benefits upfront for tax purposes.

If you find your Social Security check is less than what you expected, it’s advisable to contact the Social Security Administration for clarification. You can reach them via phone or visit a local field office for assistance.
