IRS 1099-NEC Rules (Oklahoma Contractors)

Under current US IRS rules, any single client that pays you $600 or more in a calendar year must issue you a Form 1099-NEC. Every invoice you send should include your legal business name, EIN or SSN, the client's full details, a unique invoice number, itemized line items, and the total. Keep PDF copies for at least 3 years (7 years if you underreport income by 25%+). This generator formats all of these fields correctly.

Oklahoma Plumbing Invoice Generator — FAQ

In most cases, Oklahoma does not tax pure labor/services for plumbing, only tangible goods (parts, materials) sold with the service. The state base rate is 4.5%. If you sell materials, add sales tax to that portion. Verify your specific situation with the Oklahoma Department of Revenue.
