$320K of collected tax sitting unremitted, 38 filings open, 30 of them already overdue. Tax turns the filing calendar into a scored queue: every return carries its prep progress, its liability and its penalty exposure.
The penalty proxy prints its own formula: liability × risk × 8%. A $25K exposure is not a scare word — it is arithmetic you can check.

01 — Overview
The compliance position, unvarnished
Open liability $320K, 30 overdue filings, 8 jurisdictions on nexus watch, and a compliance score of zero — the ring does not flatter the book. Alerts price the work: 17 high deadline-risk filings at $325K, and 87 exempt lines needing a certificate audit sample.

Who runs it
Three roles get the filings out.

How it runs
A filing's life, in the order it actually happens.
01
Rate
Transactions are taxed as they land — 340 lines in the demo period — with exempt and zero-rate lines kept visible for the certificate sample.
02
Watch
Nexus builds quietly: the heat map colours each jurisdiction by threshold proximity, so registration is a decision you make, not a letter you get.
03
Prep
Each return carries a prep percentage; the deadline board sorts by risk × liability so the $25K penalty proxy is worked down in the right order.
04
File
Statuses move Due → Prep → Ready → Filed, with amendments kept in the same book — 30 are late now, and the screen says which to fix first.
One record
The taxed line is one record across the estate.
These captures come from one demo workspace — Northline Systems — so the transactions being taxed are the same records the rest of the finance apps keep.
Finding this out on the third call is worse for you than reading it here, and worse for us.
Tax is not generally available. What opens today is the live build running on demo data — the 72 filings and 340 taxed lines are the demo period, not your obligations.
We have no named customers to show you, so this page shows none. Northline Systems in the captures is the software's demo workspace, not a reference.
We are not claiming to file anything: the build tracks prep progress and deadlines, and no capture shows a submitted return or an agency receipt.
Rates, thresholds and the 8% penalty factor are the demo's configuration, printed on screen. They are not tax advice, and your obligations are yours to determine with your adviser.
No audit or compliance certification has been issued for Tax. What we can evidence about hosting, encryption and access is on the security page.
Yes. Every screenshot is a capture of the running build and you can open the same build at /app/tax. It runs on demo data.
Does it file returns for us?
No, and the page does not claim otherwise. The build tracks 72 filings with prep progress, deadlines and penalty exposure — preparation is visible, submission is not asserted.
How is deadline risk computed?
Visibly: the penalty proxy prints its formula — liability × risk × 8%. Each filing carries its risk percentage, prep progress and days-overdue; two prep levers cut the simulated penalty from $25K to $12K.
What does the nexus heat map measure?
Registration risk per jurisdiction — economic threshold proximity, with ≥85% flagging the watch list. 36 cells are coloured from act-now red (Tennessee 98%) to calm, and each cell links to its evidence.
Is Tax audited or certified?
No certification has been issued, and nothing on this page is tax advice. What we can evidence about hosting, encryption, tenant isolation and production access is written up on the security page.
The calendar is open. Go and look at it.
