Washington Filings for Owners Selling a Business

These are the state and city filings that most often slow a Washington closing, written for the seller.

Each guide explains what the rule is, what you file, and what the buyer will ask you for. They are general information, so confirm your own situation with a CPA or attorney.

To see how these fit into the whole sale, read selling a business in Seattle.

    What happens to your L&I workers' comp and ESD unemployment accounts when you sell a Washington company: what transfers, what you close and what buyers ask for.

  • REET on a controlling interest sale

    Selling 50% or more of a Washington company that owns real estate can trigger real estate excise tax on the full property value. What sellers file and when.
