Risk classes reported by hour
Some of the common risk classes for the drywall industry that are reported by hour:
- Stocking and delivery in classification: 1101
- Metal studs or remodeling in classification: 0516

- Report all of their hours in the higher rated risk class.
Records you must keep for drywall installation or finishing
- Worker records:
- Full name
- Social security number
- Dates of employment
- Risk class worked in
- Basis of pay
- Gross & net pay earned
- Time records with days and hours worked
- Records of square feet of drywall installed or finished
- Workers’ withholdings
- Subcontractor records:
- UBI number
- Legal name
- Contractor registration number and expiration date
- If you supply materials to the subcontractor:
- Type of material
- Square footage of material
- Date material supplied
- Project name & location
- Date work was completed
- Jobsite records:
- Job names and locations
- Square footage of wallboard purchased for each job
- Owner hours, by job and by risk class
- Workers’ hours, by job and by risk class
- Square footage processed by subcontractors, by job and by risk class
Avoid prime contractor liability
To protect your business from paying your subcontractor’s unpaid workers’ compensation premiums you must:
- Make sure the subcontractor meets the definition of an independent contractor as outlined in the Independent Contractor Guide and in RCW 51.08.180, RCW 51.08.181, and RCW 51.08.195.
- Verify that you and your subcontractors are properly registered and/or licensed by using our Verify a Contractor tool.
- If you have a specialty license, you cannot subcontract out any work.
- Confirm the work is described as contractor work in RCW 18.27.010.
- Verify that your subcontractor has a workers’ compensation account in good standing by using our Verify a Contractor tool. Using this tool you can:
- Print a copy of their employer liability certificate. This copy is good for a year.
- Complete a subcontractor Tracking Request form and we will notify you if your subcontractor falls behind on workers compensation requirements
Worker withholding for drywall installation or finishing
The 3 ways you can calculate the amount to withhold from a worker's pay to fund the cost of workers’ compensation are:
- Actual square footage processed
- We recommend you use this method. You must keep accurate records of the actual square footage each worker processes.
- 125 sq ft per hour method
- You may use the 125 sq ft per hour method to calculate the amount to withhold IF the total square footage calculated in this method isn’t more than the amount purchased.
- Worker percentage worked method
- Only use this method if the total calculated using the 125 sq ft method is more than the amount purchased.
|Rates in this table are not actual rates and are ONLY for these examples|
|Actual Square Footage processed example||
1,500 sq. ft. x $0.01230 = $18.45.
The payroll deduction for Steve would be $18.45
|125 sq ft per Hour method example||
125 sq. ft. x 8 hours = 1,000 total sq. ft.
Then multiply that number by the payroll deduction rate:
1,000 x $0.01230 = $12.30
The payroll deduction for Joe would be $12.30
|Worker Percentage Worked method example||
45 (Joe) + 45 (Mary) + 15 (Zoey) + 15 (Steve) = 120 total hours worked
Divide the hours worked by each employee by the total hours worked to find the percent worked by each employee:
45 ÷ 120 = 0.375 (37.5% of the total hours)
15 ÷ 120 = 0.125 (12.5% of the total hours)
Multiply this percent by total sq. ft. purchased and the payroll deduction rate to find the payroll deduction for each employee:
The payroll deduction for Joe and Mary would each be:
0.375 x 12,500 x 0.01230 = $57.66
The payroll deduction for Zoey and Steve would each be:
0.125 x 12,500 x 0.01230 = $19.22
The same amount of square footage purchased needs to be reported in both the installation and taping classifications, unless:
- A legitimate subcontractor performs some of the work.
- The owner does some of the work AND submits an owner deduction form.
- The owner installs (and scraps) and finishes (tape, texture and prime) the project without the help of any workers.
- The firm reports install phase in one quarter & the taping phase in the next quarter (reporting square feet in the quarter the phase was completed).
Types of deductions
The two types of deductions you can take from the amount of square feet reported are:
- Owner deduction
- Subcontractor deduction
- Don't deduct material scrapped by you or your employees
- Don’t deduct material only scrapped or primed and textured by subcontractors
- Don’t deduct footage from the taping classification that was left unfinished, for example:
- The base layer on a multi-board application (like in a movie theater)
- An unfinished room (like a basement or garage)
Note: If you have elected to have owner coverage then you can’t take an owner deduction, and the owner’s hours and/or square footage are included for workers’ compensation coverage.
|IF the owner and workers worked side by side, follow these four steps to determine owner and worker exposure for drywall activities :||
|IF your owners worked the entire taping or entire installation:||You can deduct the full amount for the installation or taping by reporting all of the square footage in the owner’s field on the Owner/Subcontractor Report for that job|
Subcontractor deductions You may deduct work processed by the subcontractor from your total square footage purchased in the risk classification the work was performed.
Note: Material that is only scrapped or only primed & textured by subcontractors can’t be deducted.
|In order to deduct, you must:||
|Records you must keep to deduct work processed by the subcontractor:||
Drywall industry owner/subcontractor report
Complete the drywall industry owner/subcontractor report if there was any owner or subcontractor activity during the reporting period.
Information you’ll need to prepare the Owner/Subcontractor Report:
- Job names and locations
- Square footage purchased for each job
- Owner hours (by job and classification)
- Employees’ hours (by job and classification)
- Subcontractor footage (by job and classification)
You must do two things:
- Keep daily time records for the owner and employees to substantiate the percent of owner deduction.
- Determine total square footage for each job. To do this you must:
- Compute owner deduction.
- Determine subcontractor square footage worked installing and taping.
- This includes drywall board purchased and also provided by others such as a general contractor.
Discounted drywall rates supplemental quarterly report
Gather the following information you’ll need to prepare the supplemental quarterly report for the drywall industry:
- Workers' names
- Social Security numbers
- Gross wages
- Basis for pay (piece work, hourly, etc.)
- Risk classes and rates per unit/hour (you can find this on your annual rate notice or using the Verify a Contractor tool)
- Work performed (this is required for businesses reporting in the discounted classifications)
Fill in the report, listing all employees who worked for your business for the period being reported.
Quarterly reports for drywall
- Report the square footage of drywall purchased during the quarter, or
- Report the square footage on each project completed during the quarter
Note: You must use the same reporting method each quarter
- You will file the grand total square footage for both the installation and taping
- If you have used any sub contractors, an owner deduction, or have discounted rates, you will be required to file additional supplemental reporting as well as a Quarterly Report
- 125 sq ft per hour withholding method can’t be used to calculate premiums
|What to report||Example|
|Square feet your business purchased||2,500 sq ft|
|Square feet your business installed||1,000 sq ft|
|Square feet subcontracted||1,500 sq ft|
|Square feet owner installed (if qualified)||500 sq ft|
|Total square footage reported in both installation and taping drywall risk classes||1,500 sq ft|
Risk classes reported by hour (for example stocking or metal stud installation)
Multiply the total hours your workers worked by your rate for the appropriate risk class or use the Claim and Account Center
