What is the ‘Daughter Tax?’
When I was 16, my aunt was diagnosed with terminal colon cancer. She was like a second mother to me and a cornerstone of our first-generation immigrant family. Until then, I understood illness as something that happened inside a hospital: a diagnosis, a doctor, a treatment plan. What happened next taught me how incomplete that picture was.
As my aunt became sicker, my mom became her primary caregiver. The daily work of care moved into our home. My aunt had also been an important part of our family business, so when she could no longer work, I stepped further into the business and became a kind of financial caregiver too, helping keep things afloat while my mother cared for her. I was 16. I was interning at NASA and thought I was going to become an aerospace engineer. Instead, I was watching illness quietly redistribute the labor of an entire family. And much of that labor moved from one woman to another.
There is now a phrase for part of this: the “Daughter Tax.” popularized by journalist and author Kelli María Korducki. It describes the financial, professional and personal cost that so often falls on daughters when parents or relatives need care. Sons care too, of course. But women are still more likely to become primary caregivers and absorb more of the unpaid care and coordination. The word “tax” can sound cold when the care itself comes from love. My mother did not think of caring for her sister as an economic transaction. Neither did I. But love does not make the cost disappear.
The Cost We Don’t Put on the Family Balance Sheet
When people hear “long-term care cost,” they usually picture a bill: home care, assisted living, memory care, a nursing facility. But when a family cannot or does not purchase all of that care, the care does not disappear. Someone provides it. Often, that someone is a daughter.
The cost may look like reducing her work hours. Turning down a promotion. Leaving the workforce during peak earning years. Losing retirement contributions. Paying for travel, groceries or home modifications. Or simply becoming the person who schedules appointments, talks to doctors, calls insurers, researches facilities, updates siblings and holds together dozens of decisions no one ever formally assigned to her. Because so much of this work happens inside a family, we rarely price it. That is what makes the Daughter Tax so easy to overlook. It does not arrive as one giant invoice. It accumulates quietly across hundreds of decisions women make because someone they love needs them.
My family’s experience is ultimately what led me to build Waterlily. After my aunt died, I studied Genetics and Data Science at UC Berkeley and spent years building technology. Later, I started asking whether what had happened to us was unusual. It wasn’t. I kept hearing different versions of the same scramble. Families had spent decades preparing financially for retirement, but had almost no plan for what would happen if someone lost their independence. They did not know how much care might be needed, how long it might last, what it could cost or how much would ultimately fall on family.
Making the Invisible Plan Visible
One of the simplest exercises I have seen families do is this: pretend your parent needs care tomorrow. Who gets the first call? Who misses work? Who finds the caregiver? Where does your parent want to live? Who knows what they can afford? If there is a cognitive decline, who can access the right accounts and make decisions? Who coordinates everything next month? What about three years from now?
A family can have significant assets and still be profoundly unprepared. And in many families, everyone already knows the answer to those questions before anyone says it out loud. Her. That does not mean parents consciously decide their daughter should sacrifice her career or financial security for them. Usually, nobody made that decision at all. That is exactly the problem. When there is no care plan, the absence of a plan becomes the plan. And when something happens, the person who is most capable, available, emotionally connected or expected to step in does. Very often, she is a woman.
I don’t think daughters should have to choose between being loving and protecting their own future. We can plan better than that.
Planning is Not About Loving our Families Less
I want to be careful here because the answer is not to tell women to care less. My family stepped in because we loved my aunt. The problem was not that we stepped in. The problem was that we had no plan other than stepping in. There is an important difference.
A real care plan asks questions while everyone still has choices. Where do you want to receive care? What can you afford? Do you expect your children to help? Have you actually asked them? What can they realistically provide without jeopardizing their own financial security? What should be family care, and what should be paid care? If staying at home matters to you, what would that actually require? These conversations can feel uncomfortable. But I think they are ultimately an act of care.
At Waterlily, we try to help families rehearse the event before it happens. The point is not simply to give someone a probability that they may need long-term care. A percentage does not tell a family what to do. The useful questions come next. What if care lasts two years versus seven? What if you want to stay at home? How much help might that require from your family? What would professional care cost instead? What happens to your spouse? What happens to your children’s careers and finances?
If we can personalize the risk, we can make those decisions personal, too. Sometimes the answer is insurance. Sometimes it is intentionally setting aside assets. Sometimes it is changing where you plan to live or putting legal documents in place. Sometimes it is simply talking to your children years earlier than you otherwise would have. The goal is not any one financial product. The goal is to make sure “the daughter will handle it” never becomes a family’s care strategy simply because nobody planned otherwise.
We talk about the motherhood penalty, the retirement gap and equal pay. We should also be protecting women from another economic burden that often arrives later in life and receives far less attention: becoming the default infrastructure for everyone else’s aging. My family learned these lessons when we had very few choices left. That is ultimately why I built Waterlily: to give families enough foresight that care can become a shared plan instead of an inherited obligation. I want daughters to be able to care for the people they love without quietly sacrificing the futures they have worked so hard to build.
