GOAT.tax vs InvoicePlane: 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 InvoicePlane?
InvoicePlane's 1.7.2 is a mass security remediation, still working through its release candidates.
InvoicePlane is a self-hosted PHP invoicing and quoting application. The 1.7.2 line, now at its second release candidate, is dominated by security remediation: roughly thirty researchers are credited across the beta and RC notes for responsibly disclosed vulnerabilities, with severity, CVSS and GHSA advisories held back until the final release. The RC also warns that installations running custom invoice and quote templates must take manual steps before upgrading.

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.
InvoicePlane
5.0FINANCE
InvoicePlane's 1.7.2 is a mass security remediation, still working through its release candidates.
◆ Current state
InvoicePlane is a self-hosted PHP invoicing and quoting application. The 1.7.2 line, now at its second release candidate, is dominated by security remediation: roughly thirty researchers are credited across the beta and RC notes for responsibly disclosed vulnerabilities, with severity, CVSS and GHSA advisories held back until the final release. The RC also warns that installations running custom invoice and quote templates must take manual steps before upgrading.
◆ Where it's heading
The project has spent this cycle absorbing an unusually large volume of external vulnerability reports while simultaneously modernising the platform — PHP 8.2 compatibility arrived on the 1.7.0 branch, and Stripe and PayPal were reintroduced at 1.7.2 beta 1 after having been absent. The decision to withhold advisory details until 1.7.2 goes final is a deliberate disclosure posture, meaning the true scope of what these releases fix is not yet public. Release notes here are dominated by hashes and contributor credits rather than change detail.
◆ Prediction
The final 1.7.2 release and the simultaneous publication of the security advisories are the clear next step, given RC 2 is described as working toward it. Whether further RCs intervene depends on what testing surfaces.
