Action path

What to do before relying on any date.

Use this as a triage path. Confirm the official rule, identify whether the problem applies, then use the specific product only if the gap is real.

Step 1

Build a reusable chase board rather than treating each quarter as a new project.

Step 2

Separate calendar-period deadlines from the final Self Assessment return deadline.

Step 3

Keep an evidence trail for client contact, missing records and software readiness.
