Firefly III vs GOAT.tax: editorial side-by-side

F5.0

Firefly III keeps tagging develop builds daily, still with no release notes.

◆ Current state

Firefly III's feed remains automated develop pre-releases. November 12 and 13 added two more develop tags and another boilerplate development release, on top of four on November 12 alone. None includes a changelog.

◆ Where it's heading

The project is in a pre-release stretch where builds ship several times a day without notes. The feed shows activity but not what is changing.

◆ Prediction

The feed does not show what the next stable release will contain; a tagged version with a changelog is the next thing worth watching.

GOAT.tax
FINANCE
5.0

GOAT.tax calculates the federal R&D credit for whole controlled groups.

◆ Current state

GOAT.tax's October 28 release adds Controlled Groups: set up related companies as one group, enter gross receipts, calculate the federal R&D credit at group level and produce group Web and PDF deliverables, with partner portal access. It builds on the Controlled Group data model, multi-company support and October's Form 6765 Section G reporting.

◆ Where it's heading

The product is moving from single-company studies to group and partner workflows that larger filers and advisory firms need. Recent releases each add one piece of that structure.

◆ Prediction

Expect state credit calculations at controlled-group level next, since the release covers federal credits only.
