A good CPA pays for themself. The wrong one costs you in missed deductions and surprises. Here is how to find the right one.
What to look for
- Other contractor clients in your trade or size.
- Job costing and work-in-progress experience.
- Washington B&O, sales tax and payroll. See sales tax for contractors.
- Proactive tax planning, not just year-end filing.
Verify the license
The Washington Board of Accountancy site at acb.wa.gov links a "License/Discipline Search - Washington Individual" and "CPA Verify" for license checks.
Questions to ask
- How many contractor clients do you have?
- What is included in the fee, and what is extra?
- Who does the work, you or staff?
