Employer payroll tax filings

Detects completed employer payroll tax and withholding filings: Queensland (state) payroll tax returns and annual reconciliations, PAYG withholding annual reports, Single Touch Payroll pay events/finalisation summaries and US Form 941/940 returns, with populated wage/withholding totals and an employer identifier or reporting period.

Type: regex
Engine: boost_regex
Confidence: low
Confidence justification: Low: employer payroll tax and withholding filings are aggregate, entity-level business records (total wages, tax withheld, employer identifiers) that normally carry no person-level data. The pattern is capped at 75: it needs a populated amount line plus a populated employer identifier or reporting period, which separates real returns from guidance, but no tier claims 85 because the record itself is low sensitivity. Tiers are heuristic evidence levels, not measured accuracy.

Known false positives

Policies, procedures, regulator guidance, fact sheets and training material that name the record type. Mitigation: Enforce tiers require populated fields; guidance has labels without values, and policy/guidance/training/media-release framing is excluded by the NOT-group.
Blank forms, templates and system configuration screens. Mitigation: Blank lines, bracket placeholders, XXX and n/a/tbc values are rejected by the placeholder guard; template/fixture words are excluded by template-exclusion.
News, statistics and vendor marketing. Mitigation: No populated person or record fields, so these stay at 65 discovery.
Payroll software and accountant marketing that shows sample totals. Mitigation: Marketing framing (payroll software, book a demo, free trial) is excluded; the pattern is capped at 75 so it never reaches high confidence on its own.
