How Social Security tax overpayment happens with two jobs
When you work two jobs, each employer withholds Social Security tax at 6.2% without knowing what your other employer is withholding. The problem occurs when your combined wages from both jobs exceed the Social Security wage base of $176,100 for 2026. Since Social Security tax only applies to wages up to this limit, any withholding above this amount is an overpayment that you can recover.
According to IRS Publication 15, each employer is required to withhold Social Security tax on all wages paid up to the wage base limit, regardless of what other employers have withheld. This creates the overpayment situation.
Example: Two jobs exceeding the wage base
Let's say you earn $100,000 at Job A and $85,000 at Job B in 2026, totaling $185,000:
Job A Social Security withholding:
Job B Social Security withholding:
Total withheld: $6,200 + $5,270 = $11,470
Correct amount owed:
Your overpayment: $11,470 - $10,918.20 = $551.80
How to claim your refund on Form 1040
The excess Social Security tax withheld appears as a refundable credit on your tax return. Here's the step-by-step process:
1. Add up all Social Security wages from your W-2 forms (Box 3 on each W-2)
2. Add up all Social Security tax withheld (Box 4 on each W-2)
3. Calculate the maximum tax owed: $176,100 × 6.2% = $10,918.20
4. Enter the excess on Line 71 of Form 1040 ("Excess social security and tier 1 RRTA tax withheld")
The IRS will include this amount in your total refund, even if you owe income tax on other parts of your return.
When this applies to your situation
What you should do
1. Gather all W-2 forms from both employers
2. Use our paycheck calculator to verify your withholding amounts
3. File Form 1040 claiming the excess Social Security tax on Line 71
4. Keep records of your calculation in case the IRS has questions
For future years, consider asking one employer to stop Social Security withholding once you've reached the wage base at your primary job.
Key takeaway: If two employers withheld Social Security tax on combined wages over $176,100, you can claim the excess as a refundable credit on Line 71 of Form 1040, typically receiving the refund within 21 days of e-filing.
Key Takeaway: Claim excess Social Security tax withheld by two employers as a refundable credit on Line 71 of Form 1040 when combined wages exceed $176,100.

Best for high-income earners who are more likely to exceed the Social Security wage base with multiple jobs
Why high earners commonly face this situation
As a high-income earner, you're more likely to exceed the Social Security wage base of $176,100, especially if you work multiple jobs, change jobs mid-year, or receive bonuses. Each employer withholds Social Security tax independently, creating frequent overpayment situations.
This is particularly common if you:
Strategic withholding considerations
Unlike lower-income workers, you should proactively manage your Social Security withholding. If you know you'll exceed the wage base early in the year at your primary job, you can:
1. Request that your secondary employer stop Social Security withholding once you've reached the limit elsewhere
2. Adjust your W-4 at the secondary job to account for the overpayment
3. Plan for the refund as part of your tax strategy
The Medicare tax difference
Remember that Medicare tax (1.45%) has no wage cap, so you'll owe this on all wages. Additionally, you'll pay the 0.9% Additional Medicare Tax on wages over $200,000 (single) or $250,000 (married filing jointly). This creates a more complex withholding situation that our paycheck calculator can help you navigate.
Key takeaway: High earners should actively manage Social Security withholding across multiple jobs since exceeding the $176,100 wage base is more likely, and the overpayment can be substantial.

Best for newer workers who may not understand how Social Security withholding works across multiple employers
Understanding the basics of Social Security withholding
As someone newer to the workforce, it's important to understand that Social Security tax is withheld from every paycheck at 6.2%, but only up to a wage limit. In 2026, that limit is $176,100. Most entry-level workers won't reach this limit, but if you work two jobs, you might still end up in an overpayment situation.
When this might affect entry-level workers
While less common, entry-level workers can face Social Security overpayment in these situations:
Simple example for lower wages
Say you work Job A earning $40,000 and Job B earning $30,000, totaling $70,000. Both employers will withhold Social Security tax normally:
Since $70,000 is well below the $176,100 wage base, no overpayment occurs. However, understanding this concept prepares you for career advancement when higher wages make overpayment more likely.
What to watch for on your paystubs
Look for "OASDI" or "Social Security" deductions on your paystub. The year-to-date amount should not exceed $10,918.20 across all your employers combined (6.2% × $176,100).
Key takeaway: Entry-level workers rarely exceed the Social Security wage base, but understanding how multiple employers withhold independently prepares you for future career situations.
