Plain-English summary
A lawyer asked about charging Washington State business and occupation (B&O) tax on the lawyer's billing and including that tax as part of the fee. The committee was of the opinion that the lawyer is prohibited from charging the B&O tax as part of the fee.
The committee's reasoning was that the B&O tax is not a sales tax, so a charge presenting it as one (a separately passed-through tax like a sales tax) would be misleading.
Currency note
This opinion was issued in 1995, before the Washington State Bar Association's adoption of the 2006 revisions to the Rules of Professional Conduct. Subsequent rule amendments or later opinions may have changed the analysis. Treat this page as historical context, not current guidance. Verify against current rules before relying on any specific rule, deadline, or requirement mentioned here. RPC 1.5 corresponds to ABA Model Rule 1.5 on fees.
Common questions
Q: Can a lawyer pass the B&O tax through to the client as a separate charge?
A: No. The committee said the lawyer is prohibited from charging the B&O tax as part of the fee because it is not a sales tax and the charge would be misleading.
Q: Why does it matter that the B&O tax is not a sales tax?
A: The committee tied the prohibition to that distinction: presenting the B&O tax as a pass-through charge like a sales tax would mislead the client.
Background and rules framework
The opinion applied RPC 1.5 (fees, corresponding to ABA Model Rule 1.5). The committee treated billing the B&O tax to the client as a separate fee component as a misleading characterization, since the B&O tax is a tax on the lawyer's business rather than a sales tax on the client's purchase.
