Executr

The calculator answers one question: what's the tax bill? That's the easy part. The hard part is everything that comes after — and that's what we're building next.

The problem

Being an executor is an administrative job handed to someone at the worst possible moment. There are forms with no obvious starting point. There are perhaps thirty institutions to contact, each with its own process, threshold and reference number. There are deadlines that run whether or not anyone has told you about them. And there is no system — most people do it with a notebook, a shoebox of letters and a growing sense that something has been missed.

If you'd like an early look at Executr, or you're going through probate now and want to tell us what's driving you mad, we'd genuinely like to hear it.

What Executr will do

1. Generate the probate forms

Answer plain questions once, and get the right forms filled in — PA1P or PA1A, and the Inheritance Tax account with the schedules that actually apply to the estate. No re-entering the same figure into six places, and no guessing which of the IHT4xx schedules you need.

2. Track every account, asset and task

This is the part that matters most and that nothing really does well. A single live register of every bank account, pension, policy, utility, subscription and share holding: who you contacted, when, what reference they gave you, what they need next, and what's still outstanding.

Not just the probate steps — all of it. Closing the mobile contract, cancelling the car insurance, redirecting the post, notifying the council. The long tail that nobody warns you about and that keeps surfacing for a year.

3. Help distribute the estate afterwards

Once the grant is issued, work out who gets what, keep the estate accounts, record the payments made, and produce something you can actually show the beneficiaries.

4. A vault for the important documents

The will, the deeds, the policies, the certificates, the account list — in one place, so the next person doesn't have to go through the shoebox. Set up before it's needed rather than reconstructed after.

Where it's up to

In design. The calculator you're using came first deliberately — it's useful on its own, and it tells us what people actually need help with.

In the meantime

The guides cover the ground an executor needs first: whether probate is needed at all, what it costs, and how long it takes.
