The Family CFO: When Tracking Everything Still Leaves You Blind
"C" and I reconnected last year after 25 years. Same sharp mind. Same thoughtfulness. Different continent: she's in Boston, I'm in Europe.
Ten minutes into the call, we found that our families run on the same operating system. In both households, one person is the financial one. The one who remembers. The one who tracks. The one who makes sure the machine doesn't quietly break.
In my family, it's my wife. In hers, it's her. She's a product manager by day and the family CFO always.
The Routine
Every month, the same pattern. She opens the cash-flow app and categorises transactions. Then the retirement accounts: hers, her husband's, the old ones from previous jobs. Then the spreadsheet for two rental flats: rent in, insurance out, maintenance. Then equity compensation for both of them, with its vesting dates and exercise windows.
Three hours a month, for years. She does everything right. Most people would call her diligent. I'd say she is working at the limit of her tools.
The Question the Tracking Can't Answer
Midway through the call she mentioned her daughter, fifteen, set on medicine. Four years of undergraduate study, four of medical school, years before she earns anything. Close to a million dollars over a decade, starting in three years.
"Can we do both? Medical school and retirement? I don't know, but we will." Then a pause, the kind that comes with a realisation. "I don't actually know. We'll figure it out as we go."
She has complete visibility into every account. What she doesn't have is an answer, because the answer isn't in any one account. It depends on what the rentals really return after costs, what pulling a large sum every year from 2028 does to everything else, and how equity and tax turn into usable cash. The tools give her snapshots. What she needs is memory.
Now Give the Same Job a Second Country
C's household lives in one country, under one tax system, in one currency. It is still a three-hour monthly job that can't answer its own most important question. The family CFO of a cross-border household in Europe is doing the same job with two or three of everything.
- Two tax years that don't line up: India's runs April to March, most of Europe's runs January to December.
- Statements in two or three languages, from banks that don't know about each other.
- A Box 3 valuation, or a Swiss wealth tax list, built from balances on a single date in currencies that moved since.
- TDS certificates for NRO interest, a property tax receipt for a flat in Bengaluru, a pension overview from each country someone in the family has worked in.
- A chartered accountant in one country and a tax adviser in another, each seeing their half, neither ever speaking to the other.
And their version of C's question is harder. Medical school where: India, the Netherlands, the United States? Paid in which currency, from which country's savings? Retirement in which country, drawing on which pensions? Each of those answers changes the others.
The part nobody plans for
In most cross-border households, one person holds the map of what exists where. If that person is unavailable, the rest of the family doesn't have a picture. They have a set of logins they may not know about, in countries whose rules they don't know.
The Burden Isn't the Work
The work is hard, but that isn't what wears people down. The uncertainty never goes away. The family CFO is doing the job properly and still can't answer the one question the job exists for. The tools were built to record what happened, one country at a time, and the question is about what happens next, across all of them.
If you're the one who carries your household's financial picture across countries, do you know the answer to your version of C's question?
A blog post can tell you the rule. It can't tell you what it means for your accounts, your dates, your numbers. That's a conversation, not a search result.

The Complexity Tax: What Accounts in Three Countries Actually Cost You
Ten to fifteen accounts across three countries is normal for a cross-border household in Europe. The cost hides in NRO tax nobody reclaims, deadlines in three calendars, Indian accounts that go inoperative after two years, and reporting that doesn't match what the tax office already knows. The largest cost is the decisions that never get made.
Your FIRE Spreadsheet Doesn't Work When Your Assets Live in Three Countries
My spreadsheet started as a list of what I own. It grew a tab for every question, and broke on the only one that matters: when is it enough? The 4% rule comes from US market history; across seventeen countries it survived the worst case in only four. For a household spending euros with assets in rupees, currency, withdrawal tax and money that can't move freely break the model.
The Document Problem: What Your Family Won't Find If Something Happens to You
When my grandmother died in Bangalore, the will and the assets didn't match, and she had lived in one city all her life. A cross-border household's estate is spread across documents in several countries, a nominee is not an heir under Indian law, and EU and Indian succession rules can each claim a piece of the same estate.
