5 Moves To Make in Your 40s To Get More Social Security in Your 60s

Social Security might feel like a distant concern when you are in your 40s. But the decisions you make about your career, your income, and your earnings record right now are quietly shaping the benefit you will collect in your 60s and beyond. 

If you want to make the right moves before that window closes, your 40s are the best time to act because the higher earnings you build now feed directly into the formula that determines your monthly check.

Here is how it works and what you can do about it.

How Social Security actually calculates your benefit

Before getting to the moves, it helps to understand the math behind the benefit. Social Security bases your retirement check on your 35 highest-earning years, with each year's wages adjusted for inflation using the national average wage index. Those 35 years are averaged into a monthly figure called your Average Indexed Monthly Earnings, or AIME. A progressive formula is then applied to AIME to produce your Primary Insurance Amount, which is your benefit at full retirement age.

If you worked fewer than 35 years, Social Security fills in the missing years with zeros, which drags your average down significantly. If you worked more than 35 years, the lowest-earning years are dropped and only the best 35 count. This structure means that every higher-earning year you add has a direct and measurable effect on your eventual benefit, which is exactly why your 40s matter so much.

Grow your income so higher-earning years replace lower ones

The most direct lever you have on your Social Security benefit is your income. Because the formula uses your 35 highest-earning years, a high-earning year in your 40s may replace a lower-earning year from your 20s or early 30s, lifting your AIME and the benefit it produces.

This makes your 40s one of the highest-leverage decades for income growth. Whether through raises, promotions, changing jobs for better pay, or adding a side income stream, increasing your earnings now has a compounding effect because it not only adds money to your current budget, it permanently improves the calculation the Social Security Administration will use to set your benefit.

In 2026, earnings up to $184,500 are subject to Social Security payroll tax and count toward your benefit calculation. Earnings above that cap are not taxed and do not count. For most workers, there is meaningful room to grow income that still feeds into the formula.

Check your earnings record every year and fix errors

Your Social Security benefit can only be calculated from wages the SSA actually has on record. If an employer underreported your wages, made an error, or you had self-employment income that was not properly documented, those earnings may be missing from your record, and missing earnings produce a lower benefit.

The SSA maintains an earnings record for every worker, and you can review it for free at ssa.gov by creating a my Social Security account. Your statement shows your reported wages for every year you have worked, the estimated benefit you would receive at different claiming ages, and any gaps or discrepancies.

Errors are easier to correct when they are recent. Tracking down a W-2 from 15 years ago is significantly harder than correcting an error from last year. Reviewing your earnings record annually in your 40s, while tax documents and employer records are still accessible, is one of the simplest high-value steps you can take.

Make sure you hit 35 full years of earnings

If you have any gaps in your work history, your 40s are the time to think seriously about filling them. Every year you work in covered employment beyond what you have already accumulated either fills in a zero year or replaces a low-earning year, both of which raise your AIME.

Someone who took several years out of the workforce for caregiving, education, or a business that had limited income may be looking at a handful of zero years in their 35-year calculation. Working consistently through your 40s and into your 50s addresses this directly. 

If you worked fewer than 35 years, adding even one more year of covered earnings removes one zero from the average, which could produce a meaningful improvement in the final benefit.

Lay the groundwork now to delay claiming later

Claiming age is separate from the earnings calculation, but it is one of the most powerful factors in determining your actual monthly check. Your benefit is based on your PIA at full retirement age, which for most workers today is 67. 

Claiming at 62 permanently reduces your benefit by about 30%. Waiting until 70 increases it by roughly 24% above the full retirement age amount.

The connection to your 40s is that the financial foundation you build this decade determines whether waiting is realistic. Workers who reach their 60s with savings, investment accounts, and manageable expenses have the flexibility to delay Social Security. Workers who arrive at 62 with limited savings often claim early out of financial necessity, accepting a permanently reduced benefit.

Building savings aggressively in your 40s, paying down high-interest debt, and making realistic projections about when you could afford to retire all directly influence your ability to delay claiming and collect a larger monthly check.

Understand the tax tradeoff and plan around it

Earning more now to boost your Social Security benefit does come with a cost: You will pay more in payroll taxes today. Social Security is funded by a 12.4% payroll tax on covered earnings, split between employee and employer, with self-employed workers paying both sides. Higher earnings in your 40s mean higher taxes today in exchange for a larger benefit in your 60s and beyond.

For most workers, that trade is worth making, particularly because Social Security benefits are inflation-protected, guaranteed for life, and adjust upward with annual COLAs. But understanding the tradeoff helps you plan. High earners close to the $184,500 taxable maximum see diminishing returns on additional income, since earnings above that threshold do not affect the benefit calculation at all.

Bottom line

Your Social Security benefit is not set in stone, and it is not determined primarily at the moment you file. It is built year by year through the wages you earn and report, and the 35 best years of that record become the foundation of your monthly check. The moves you make in your 40s feed directly into that foundation.

If you want to make sure you are on track for retirement and maximizing what Social Security can provide, start by pulling up your earnings statement at ssa.gov and treating it as a baseline. Review the estimated benefit at different claiming ages, check your reported wages against your own records, and if there are gaps in your history or lower-earning years that could be replaced, make those years count while you still have the time to do it.
