Every April, you do something clever. You find another deduction, trim another line, and watch your taxable profit shrink. You feel like you're winning. But there is a second ledger running underneath the tax return, and it works against you. It's the one Social Security uses to decide what your family receives if you die. That ledger only knows the number on the bottom of your Schedule SE.

This is the part of founder estate planning almost nobody talks about. We obsess over passwords, domains, and who inherits the LLC. Meanwhile one of the largest sources of income a surviving family may ever receive gets calculated from tax-return decisions you made years ago, usually without thinking about them.

You are your own payroll department

When you work for an employer, half of your Social Security tax is paid on your behalf, and the wages are reported automatically. When you work for yourself, you pay both halves through self-employment tax, 15.3% on net earnings, of which 12.4% goes to Social Security and 2.9% to Medicare.

That tax builds your record. Social Security measures your work history in credits, and you can earn up to four per year. The amount of earnings required for a credit is adjusted annually and has been around $1,800 in recent years. This is a threshold, not a goal. Hit it and you bank the credit.

Most founders clear the credit threshold easily, so they assume they're covered. That's half the story. Credits decide whether your family qualifies. A different calculation decides how much they get.

Eligibility is generous. The amount is not automatic.

The good news is that survivor benefits are more accessible than most people expect. Retirement benefits generally require 40 credits, about ten years of work. Survivor benefits for a young family can be triggered with far fewer. If you die young with children, they may qualify based on as few as six credits earned in the three years before your death. Younger workers who haven't had time to build a decade of history still protect their families.

Who can receive benefits, in broad strokes:

  • Unmarried children under 18 (up to 19 if still in high school full time), and disabled adult children whose disability began before 22.
  • A surviving spouse caring for a child under 16 or disabled, at any age.
  • A surviving spouse without children, with benefits available as early as age 60, at a reduced rate, or in full at full retirement age.
  • A one-time lump sum of $255, paid to a qualifying spouse or child. It's a token amount. It won't cover the funeral home's first invoice.

A child's benefit is typically around 75% of what your own retirement benefit would have been. A spouse caring for a child receives a similar 75%. There is, however, a family maximum, generally somewhere between 150% and 180% of your basic benefit, so three children don't triple the check.

For a family that has just lost its only income, that monthly payment, which is tax-advantaged in many cases and inflation-adjusted, can be the most reliable cash flow they have. Unlike your business revenue, it doesn't depend on anyone being able to log into anything.

The quiet trade-off: tax minimization versus benefit maximization

Here is where the deductions come back to bite.

Social Security calculates your benefit from your average indexed monthly earnings, built from your highest-earning years of recorded income. For the self-employed, recorded income means net earnings from self-employment: profit after expenses, as reported on your tax return.

That means every legitimate dollar you deduct is a dollar that doesn't count toward the formula. Deduct heavily and you pay less tax today. You also lower the monthly income your children and spouse could receive for years.

This isn't an argument to stop taking deductions. They're legal, and often wise. But it is a real trade-off that deserves a conscious choice, not an accident. A founder with a net profit of $40,000 on $160,000 of revenue has a very different benefit record than the one who reports $90,000, even though the businesses might look nearly identical from the outside.

The benefit formula is also progressive. It replaces a larger percentage of lower earnings and a smaller percentage of higher ones. That means the first dollars of reported income do the most work. If your net earnings sit barely above the credit threshold year after year, you may be forfeiting protection at exactly the point where each reported dollar buys the most.

The other thing that goes wrong: nobody files the claim

Even a perfect earnings record does nothing if no one knows to ask. Survivor benefits aren't paid automatically. Someone has to contact the Social Security Administration, usually within a short window of the death, to report it and apply. Funeral homes often report deaths, but reporting a death is not the same as applying for a benefit. A grieving spouse who assumes it's handled can lose months of payments, since retroactive coverage for survivor benefits is limited.

The application will ask for documents your family probably can't find at 2 a.m.: your Social Security number, the death certificate, their own marriage certificate and birth certificates, your most recent W-2 or tax return, and bank details for direct deposit. If you're self-employed, expect them to need the tax return specifically, and good luck if it lives in a folder named after a cloud service your spouse has never opened.

There's also the remarriage rule, which surprises many people. A surviving spouse who remarries before 60 generally loses survivor eligibility, while remarriage after 60 does not. Your family may someday want to know that before making a decision, not after.

Your next moves

None of this takes long. Do it this week.

  • Create or log into your my Social Security account at ssa.gov and read your earnings record. Check that every year of self-employment income shows up. Missing years can be corrected, but the window to fix old errors is limited, so don't wait.
  • Read the projected survivor figures with your own eyes. The statement shows estimated benefits for your family if you die. Write down the numbers for a spouse and for each child.
  • Pull your last three Schedule SE forms and compare net earnings to gross revenue. Ask your accountant one direct question: "What is the benefit cost of the deductions we're taking, and is it worth it?"
  • Put a one-page claim sheet in your family's reach. Include the SSA phone number, your Social Security number's location (not the number in plain email), the document list above, and the sentence: "You must apply. It does not happen automatically."
  • Tell your spouse or executor out loud that these benefits exist. One sentence is enough: "If something happens to me, call Social Security within the first couple of weeks, and ask about survivor benefits for the kids."

What this really says about your plan

Most estate planning for founders is about access: who can open what. This corner of it is about income: what arrives on its own schedule, funded by taxes you've already paid, if the right person asks for it. It's worth knowing before it's needed, because the family who understands it can plan their first year around a predictable number instead of a hope.

That's the kind of detail Heirloom was built to hold. It's a place where the claim sheet, the document locations, the person who should make the call, and the instructions for what to do first all sit together, ready for someone who is overwhelmed and has never seen any of it. If you'd like to see how that looks, you can explore Heirloom at https://heirloom.lumenlabs.works. But start with the earnings record. It takes ten minutes, and it might be the most valuable ten minutes in your plan.
