Because WA DOR administers both B&O taxes and unclaimed property, routine tax audits regularly expand into unclaimed property ledger reviews.

WA RUUPA uses a $75 threshold and mandates electronic filing/payment via DOR portals.
WA DOR Voluntary Disclosure / Penalty Waiver
Electronic voluntary disclosure eliminating automatic 10% late-remittance penalties for proactive holders.
Statutory Interest & Penalties: 10% penalty for late/non-electronic filing + interest. Negative Report Policy: Not required by statute unless specifically requested or following prior positive filings.
