GOAT.tax vs Kill Bill: at a glance
What is GOAT.tax?
State credit math keeps deepening while the study tables get easier to work in.
GOAT.tax runs R&D tax credit studies end to end, from wage and expense collection through business component allocation to a filed deliverable. This release tightens three state rules at once — Colorado now requires three years in the same Enterprise Zone, Indiana Research Activities fields get defaults so deliverables are never generated incomplete, and Minnesota picks up startup treatment that derives the applicable historical years and Fixed Base Percentage method dynamically. On the workspace side, R&D allocation percentages become directly editable in BC Allocation for single- and multi-state records, and the All Studies page and BC Allocation table are rebuilt on the newer design.
What is Kill Bill?
Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.

GOAT.tax
5.0FINANCE
State credit math keeps deepening while the study tables get easier to work in.
◆ Current state
GOAT.tax runs R&D tax credit studies end to end, from wage and expense collection through business component allocation to a filed deliverable. This release tightens three state rules at once — Colorado now requires three years in the same Enterprise Zone, Indiana Research Activities fields get defaults so deliverables are never generated incomplete, and Minnesota picks up startup treatment that derives the applicable historical years and Fixed Base Percentage method dynamically. On the workspace side, R&D allocation percentages become directly editable in BC Allocation for single- and multi-state records, and the All Studies page and BC Allocation table are rebuilt on the newer design.
◆ Where it's heading
The state coverage thread has shifted from adding jurisdictions to encoding their harder eligibility and computation rules — Enterprise Zone tenure, startup Fixed Base Percentage methodology, and visible reasons when a state credit is ruled ineligible. That last one, plus the new Fixed Base Percentage details view and override, points at the same goal from a different angle: making the calculation auditable by the person running the study rather than trusting it. Fee handling entered the product this window too, with an optional not-to-exceed percentage and cap threaded through the fee structure, credit and deliverable pages.
◆ Prediction
Fee logic just appeared across three pages at once, so the next step is likely the rest of the billing path — applying the not-to-exceed cap to invoicing or partner-facing fee reporting. The notes give no schedule.
Kill Bill

Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
◆ Current state
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.
◆ Where it's heading
Reading the 0.24 line alone, the theme is invoice-generation robustness continuing from 0.24.18's error handling, retries and account parking, into 0.24.20's branding refactor. The August 12 revert of the template branding key suggests that refactor is not settled. What the 0.25 line contains is genuinely unknown from this feed — the tags exist, the notes do not.
◆ Prediction
Expect the tenant-branding work to return in a corrected form on the 0.24 line, since the revert removed the key rather than the surrounding refactor. Whether 0.25 is a development line or a release line is not something these entries answer.
