What Tax Planning Has to Do With Your Child's DAC Benefit

For years, as a planner, I've sat across from parents who were trying to do everything correctly financially. They contributed to retirement accounts, worked with accountants to reduce their tax exposure, and made smart decisions about how to structure their income. Yet many still had a blind spot that could cost their child tens of thousands of dollars over a lifetime - not because they were careless, but because no one ever connected the dots for them. I want to help you do that.

Disabled Adult Child (DAC) benefits - also referred to by Social Security as Childhood Disability Beneficiaries - allow a qualified disabled adult child to receive Social Security benefits based on a parent's earnings record. If you're not yet sure whether your child qualifies, this walks through it in more depth. The benefit is 50% of the parent’s Primary Insurance Amount (PIA) while the parent is alive and collecting, rising to 75% after the parent dies.

The PIA is the monthly benefit a worker receives at their Full Retirement Age (FRA), and Social Security calculates it using something called the Average Indexed Monthly Earnings (AIME) - an inflation-adjusted average of the worker’s highest 35 years of earnings. The higher the AIME, the higher the PIA, and the larger the DAC benefit a child may receive for 40 or 50 years.

That’s why a parent’s earnings record isn’t just a retirement planning document - it’s part of the financial foundation for a child who may never have a meaningful income of their own.

Social Security taxes - the Federal Insurance Contributions Act, or FICA, is what you see on your pay stub - fund these benefits, and they’re assessed on wages and net self-employment income. This is where the tax planning connection comes in, and where the distinction between how you earn your income matters.

If you’re a W-2 employee, most common tax strategies don’t touch your Social Security record. Contributing to a traditional 401(k) reduces your federal taxable income, but your employer still reports your full gross wages to Social Security. Your record stays intact - that particular tradeoff doesn’t apply here.

If you’re self-employed, the picture changes. Self-employed individuals pay Social Security taxes on their net self-employment income - meaning gross revenue minus business deductions. Every dollar of legitimate deduction reduces both the tax bill and the Social Security wages reported for that year. Over a 35-year working life, those reductions compound in ways that never appear on a tax return. They show up later, in a lower DAC benefit that a child may receive for decades.

S-corporation owners face a related issue. When income flows through an S-corp, the owner pays Social Security taxes only on their salary - not on distributions. Minimizing that salary to reduce what gets withheld is a well-known and legal strategy, but it also minimizes what gets reported to Social Security. A parent who takes $40,000 in salary and $100,000 in distributions has an earnings record that reflects only that $40,000 - the rest doesn’t exist, as far as SSA is concerned.

When most people weigh the tax savings from reducing their reported income against a smaller Social Security benefit later, they’re thinking about themselves - their own retirement income, their own timeline. The tradeoff is real, but it’s contained.

DAC adds another person to that equation - one who may have no other meaningful source of income, and who won’t collect for 20 years but may collect for 50. The math looks different when you’re running it for two people instead of one, and when the person with fewer options is the one who absorbs the downstream effect.

None of what I’ve described in the previous section is wrong. These are legitimate strategies that accountants recommend every day. What’s missing from most of those conversations is what happens downstream, when a child files for DAC benefits decades later.

If any of the following apply to you, it's worth bringing this question explicitly into your next tax planning conversation.

1. You run a small business or work as an independent contractor, and your accountant actively minimizes your net self-employment income to reduce your tax exposure. The same deductions that lower your quarterly payments also lower your AIME.

2. You’re the parent receiving Medicaid Waiver caregiver payments for caring for your child. I covered this in some depth in late 2024 - if those payments are excluded from income and not reported to Social Security as wages, they aren’t building an earnings record for anyone. The tax benefit is real. So is the gap it creates.

3. You’re considering reducing your work hours or stepping back from your career to manage your child’s care needs. Years out of the workforce - or years of substantially reduced earnings - leave gaps in the record that lower the AIME and, by extension, the benefit your child would eventually receive.

The point isn’t to abandon tax strategies - it’s to make sure the people helping you plan know the full picture.

Right now, most of these conversations happen in separate rooms. The accountant optimizes for the tax bill, the financial planner optimizes for retirement, and Special Needs planning - if it happens at all - tends to focus on trust structures and benefit eligibility. No one is routinely sitting at a table where all of these threads connect - which means decisions that look correct in isolation can add up to something no one intended.

By the time a child files for DAC benefits, the parent’s earnings record is largely written - there’s very little ability to go back and fix it.

Check your Social Security earnings record. The SSA makes it available at ssa.gov, and it’s worth reviewing to make sure what’s been reported looks right. Errors in the record happen, and they’re correctable - but you have to catch them.

If you’re self-employed or running an S-corporation, bring the DAC question explicitly into your next tax planning conversation. Your accountant needs to know this dimension exists. They may not have thought to ask about it.

If you’re working with a financial planner, ask them to run the projected PIA and show you what the DAC benefit would look like under your current earnings trajectory, then ask what changes if you adjust your income reporting strategy. It’s a straightforward analysis once someone knows how to run it.

If you have access to a Special Needs Planner or an estate planning attorney, this is worth raising there as well. It sits at the intersection of tax law, Social Security policy, and disability benefits - which is exactly why it tends to fall through the cracks between the professionals who are supposed to catch it.

If sorting through any of this feels like too many moving parts to hold at once, Sage can help - not by replacing your accountant or your planner, but rather by helping you understand the system well enough to walk into those conversations prepared. Ask Sage to walk you through what your DAC benefit might look like under your current earnings trajectory, or to help you build the right questions for your next tax meeting. The more context you bring, the more specific the conversation gets.
