Editorial & Accuracy Policy

Every rules page on About401K is written from primary sources (Internal Revenue Code, IRS notices, Treasury regulations, DOL guidance), states the year for every dollar figure, shows a last-updated date, and is re-verified whenever the law or the annual IRS limits change.

Sourcing

We cite the controlling authority for each rule inline. For example, the 2026 elective deferral limit of $24,500 is sourced to IRS Notice 2025-67, and loan limits to IRC §72(p). Where secondary sources are used for context, they are named and linked.

The annual limits update

Each fall the IRS publishes cost-of-living adjustments for the next year. When that notice drops, we update every affected page (limits, catch-ups, compensation caps, HCE thresholds) within days, and stamp each with the new verification date.

What we won’t do

• Publish “current year” claims without the actual year and number.
• Present plan-specific features as universal law.
• Let advertising or affiliate relationships shape a rule statement.

Corrections

Errors get fixed, not buried: material corrections are noted on the page. Report anything wrong via our contact page.
