Year-End HR Planning: Setting Up 2026 Without the January Scramble

December is the cheapest month to plan and the most expensive month to ignore. Five things to lock in before January 1 so your year doesn't start in firefighting mode.

1. Headcount plan signed off, not just discussed

By December 31 the FP&A model and the recruiting forecast need to match within 5%. Anything wider and Q1 hiring will be reactive.

2. Performance cycle dates locked

Calibration calendars, manager training slots, comp-decision deadlines — all on calendars before the holidays.

3. Compliance refresh logged

EEO updates, wage transparency in newly-covered states, GDPR sub-processor list. Build the refresh log in December so audits in March don't surprise you.

4. Tool consolidation review

If you're carrying duplicate vendors going into renewal season, decide now which contract gets cut.

5. People-data baseline

Snapshot headcount, attrition, hiring-velocity and engagement on Dec 31. Without a clean baseline, you can't measure anything meaningfully next year.
