BlackTax

Family, on purpose

Launching in Nigeria

Money you promised to family, set aside and sent on time.

Black tax is the allowance to your mother, the school fees for your brother, the aunt you help each quarter. Most people carry it in their head and send it by hand. This gives it a pot of its own, a list of who it is for, and a record of what has actually gone out.

Launching in Nigeria first.

A woman sitting at a kitchen table with a phone, looking away in thought.
The 1st of the month, decided in advance.

Nobody forgets the promise. They forget the transfer.

You said you would send it. You meant it. Then the month moved, the money was spent on something ordinary, and the transfer went out late, or short, or twice.

Not because you are careless. Because nothing in your bank account knows the difference between rent, lunch and your mother’s allowance.

The month moves faster than the intention.
Nothing sets the money aside
Nothing records what was promised against what was sent
Nothing repeats without being remembered
Nothing tells a family obligation apart from any other transfer

Four things an obligation has never had.

01

A pot

Money set aside from everyday spending, one per currency. It is yours, it sits in your name, and it is not part of what you spend on a Tuesday. It is funded from your main account and from nothing else.

Set aside is a place, not an intention.

02

Your people

The list. A parent, a sibling, an aunt, a dependent — and what you promised each of them, as a number and a rhythm. Monthly, weekly, quarterly, annually, or nothing fixed at all when the arrangement is occasional.

03

Sending

By hand when you want to, and on a schedule that does not need reminding. The 1st arrives whether or not you remembered it, and the pot pays without asking you to do anything that morning.

04

A record

What was promised, what was sent, what was skipped and why. Per person and in total. Complete enough to answer a question from your own family without having to remember the answer.

The app itself

This is what it looks like on the phone.

Four screens, taken from the built app. Amounts in naira, plain words, nothing you have to decode.

    The pot

    What is set aside, and what is still to go this month.

  • BlackTax app screen: The people

    The people

    Everyone on the list, and what each of them was promised.

  • BlackTax app screen: Schedules

    Schedules

    The standing instruction, and every run it has already made.

  • BlackTax app screen: Activity

    Sent, skipped, short — kept in plain language.

The distinction

A promise and an instruction are different things.

A pledge is what you told your mother she can count on. A schedule is the standing instruction that actually moves the money. Most apps collapse the two, and then changing one quietly changes the other. This one keeps them apart, on purpose.

One is a word given. The other opens something.

A pledge

A schedule

changing it moves no money
changing it changes what gets sent
can exist with no schedule
can exist without matching the pledge

Change a pledge and the app tells you the schedule no longer matches. It offers to update it. It never does it for you.

Two numbers, and the space between them.

What you promised this month. What has actually gone out. The difference is a subtraction, not a verdict — there are still days left in the month.

Most people are on both sides of this at once.

Giving

You have a pot. You listed your people. You promised each of them something. Money leaves on the day it should.

You see everything: the pot, every person, every run, every ask.

Receiving

Someone listed you. You can see what they promised you — and only that. You can ask, when you need to.

You see one arrangement. Not their balance, not their other people, not their schedules. Nothing else.

Most people are both. A daughter supporting her mother, supported by her brother.

How the two sides differ

An empty kitchen in early morning light with a phone face down on the table.
It fires whether or not the morning is a good one.

The 1st arrives whether or not you remembered it.

A schedule fires. The pot pays. Everyone on that schedule gets what they were promised, and every one of them gets a record — including the months when nothing was due.

And when the pot is short, the app does the thing that costs you least dignity: it pays nobody, tells you exactly why, and retries. Three of five relatives paid is worse than a clean retry.

What happens when it goes wrong

A woman sitting on the edge of a bed composing a message on her phone.
Asking, without the phone call neither of you wanted.

The other direction

A way to ask that is not a phone call.

School fees came early. A hospital bill. Something outside the arrangement. Your aunt can ask, in the app, for a specific amount and a reason — and you can say yes or no without a conversation neither of you wanted to have.

Approved and paid are two different states, and you will always see which one you are looking at.

Things it does not do.

Named here rather than discovered later.

A short list, said out loud.
No currency conversion

A pot and its people are one currency. The same relative in two currencies is two arrangements.

No sending outside BlackTax

A person needs an account. This does not reach a bank you nominate.

No lending, no IOUs

Nothing tracks what anyone owes back. It is not a debt product.

No group pots or rotating savings

That is a different thing and it is not this.

Nothing to do with a revenue authority

Despite the name.
