Does Form W-9 matter differently for Contractors in Houston?

Yes. progress billing, retainage, subcontractor compliance, materials timing, and job-cost reporting can change which records need attention before Form W-9 is reviewed for Business Advisory decisions.

Which records should be gathered first?

Start with completed W-9 forms, vendor master list, and job-cost reports. Mary Ann Hair, CPA can then reconcile the support to the return, notice, payroll filing, or report.

What is the biggest mistake to avoid?

Paying vendors before collecting tax IDs. project deposits, draws, and retainage can make taxable income look different from cash in the bank, so the response should be backed by books and source documents.

How does Business Advisory affect this question?

Business Advisory changes what needs to be reviewed first: Reports are translated into practical choices about pricing, hiring, owner draws, taxes, and cash reserves. That context keeps the page tied to a real CPA workflow instead of a generic tax answer.

When should a CPA review happen?

Make W-9 collection part of vendor onboarding instead of waiting until forms are due. For Houston construction and trade contractors, earlier review gives more room to correct records, plan payments, or prepare a documented response.
