Pick the jurisdictions where your group has entities. You get every separate filing obligation that triggers, in deadline order, with the access prerequisites that decide whether you make them — and a link you can send to your team.
How the dates are worked out. Each obligation carries the authority's own published rule — 15 months after the year end, 18 for the first in-scope year, 6 months for a registration, and so on — applied to the year end you chose. Where an authority has published no deadline, the obligation is listed without one rather than given an invented date. Every underlying rule is sourced and dated on the tracker.
This is a scoping aid, not advice, and not my employer's view. It will not know about group elections, safe harbours or exemptions that change your position. Verify against the authority before you file.
That is the usual reaction, and it is the reason the first cycle caught people out. I run the Pillar Two practice at DataTracks — close to 500 filings across eleven jurisdictions in the first live cycle.
