What CensusCheck validates 20+ automated checks
Invalid or missing SSN
Nine valid digits, no invalid IRS ranges, no duplicates — and Excel-stripped leading zeros repaired with one click.
Data integrity
Missing required fields
Flags any blank SSN, name, birth date, hire date, hours, or compensation before the file goes anywhere.
Data integrity
Duplicate participants
Catches the same SSN — or the same name and birth date — appearing on two rows of the census.
Data integrity
Date logic & sequence
Birth before hire, termination after hire, rehire after termination — plus ages outside 14–100 and future-dated entries.
Dates
Plan-year window
Termination and rehire dates outside the plan year are flagged — clear or correct the date, or remove a participant whose prior-year termination means they no longer belong on this census.
Dates
Hours reasonableness
Negative hours, unreadable values, or totals above 3,000 for the year all get a second look.
Eligibility
Compensation limits
Caps against the §401(a)(17) limit for the plan year, catches negatives, and questions zero pay with hours worked.
IRS limits
Deferral limits & catch-up
Total deferrals tested against the §402(g) limit, catch-up checked against age 50, and deferrals never above compensation.
IRS limits
Missing employees
Someone on last year’s census with no termination date who has vanished from this year’s file — resolved with a guided fix.
Prior-year
Hire date changed
Compares every hire date to last year’s census and flags any that quietly moved — you choose which date is right.
Prior-year
Compensation variance
Surfaces year-over-year pay swings of 50% or more — usually a typo, a mapping slip, or a missed status change.
Prior-year
Spreadsheet artifacts
Trailing “.0” floats, accounting-style zeros, currency symbols, and thousand separators are read correctly, not rejected.
Data integrity
Every fix is logged and re-validated instantly. Nothing is ever changed silently — each correction, cleared value, and confirmation lands in an audit trail, the engine re-runs the full rule set after every change, and anything only the client can answer goes into a ready-to-send question packet.
