Yes. A classification is the job category your payroll is rated under, and a bookkeeper who works only in a separated office qualifies for the clerical category in most states. She has to do office work only, sit behind a wall, floor, partition, counter, or similar barrier that keeps her away from the work itself, and leave that area only now and then. Who this is for: contractors whose office staff are charged at the crew's rate.
The short version
- A bookkeeper who works only in a separated office qualifies for the clerical category in most states.
- The work area must be kept apart from the shop or yard by a wall, floor, partition, counter, or similar barrier that keeps her away from the work.
- She can only leave the office now and then. Regular site visits, deliveries, or shop work break the rule.
- If she does non clerical work too, all of that pay goes to the category where most of her work sits.
- The clerical rate is often 20 to 50 times lower than a field rate.
What does clerical mean in workers comp?
Every employee's payroll is rated under a job category that sets the rate, which insurers call a class code. Most categories follow the trade, so a plumbing company's payroll is rated as plumbing. A few apply across every trade, and clerical office employees is one.
Most states follow the National Council on Compensation Insurance (NCCI) rules, and states that run their own bureau, such as California, New York, and New Jersey, use a close version of the same test. In North Dakota, Ohio, Washington, and Wyoming you buy from the state fund and it decides the category, and Washington charges by the hour worked rather than by payroll.
The rate gap is large, often 20 to 50 times, which is why this is worth checking. See should office staff cost less than field employees.
What is the test for the clerical category?
| The rule | What it means for a bookkeeper | Passes | Fails |
|---|---|---|---|
| Office duties only | Bookkeeping, payroll, billing, filing, phones | Runs payroll from a desk | Also picks up parts or works the counter |
| A separated work area | Kept apart from the shop or yard by a floor, wall, partition, counter, or other barrier, and away from the work | Office with a door, or a home office | A desk in the open shop, or a half wall by the machines |
| Outside only now and then | The bank or an occasional errand (the rule calls this incidental time) | A weekly deposit | Regular deliveries or weekly site visits |
| No supervising, sales, or physical work | Lost if she supervises the crew, does outside sales, or does any physical work | Runs the books and nothing else | Also supervises the shop helpers |
| No splitting | The clerical category cannot be shared with another one | Office only, all year | Office three days, shop two days |
The separation rule surprises owners most. The barrier has to actually keep the person away from the work. A desk in the open shop fails because the saws, the forklift, and the dust are right there, not because a wall is missing. A home office usually counts if it is away from where the work happens, so a desk in the garage you store materials in does not.
What if my bookkeeper also does other things?
Then it turns on what she does and how often. A bookkeeper who signs for a delivery once a month is still clerical. One who drives to job sites every Friday is not. The category is also lost if she supervises the crew or does any physical work.
If she works the parts counter or helps load trucks, all of her payroll is rated in the job category where most of her work falls, and in the highest rated category of all if your records cannot show the hours. See estimators and project managers for the common near misses.
How do I prove it to the insurance company?
- A written job description listing office duties and stating that the role has no shop, yard, or field work.
- A sketch or photos showing the barrier and the door.
- Payroll records by employee so the auditor sees her wages as a separate line.
- Time records if she is ever outside the office.
Send these to your broker before the policy starts, or before the premium audit, the insurer's year end check of your real payroll. If last year's category was wrong, see how to ask for a review.
How much does the clerical category save?
An illustrative example for a bookkeeper earning $48,000 at an electrical contractor. Real rates depend on state, insurer, and claims history.
| Category | Illustrative rate per $100 | Yearly premium on $48,000 |
|---|---|---|
| Electrical (the crew's category) | $4.50 | $2,160 |
| Clerical office employees (code 8810 in most states) | $0.30 | $144 |
| Difference | $2,016 a year |
For a roofer the difference is several times larger. Multiply by every office employee, and by any earlier policy years your state lets you reopen.
What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A heating and cooling contractor in Texas has a bookkeeper earning $52,000 who works at a desk in the back corner of the shop, behind a half wall. The insurer rates her at an illustrative $4.20 per $100.
What went wrong: At the audit the owner asks for the clerical category. The auditor sees the desk in the same open room as the sheet metal brake, with the dust and the traffic right there, and keeps her in the shop category.
What it cost: She costs $2,184 a year to insure instead of about $156. Over three years, roughly $6,000 in extra premium.
The fix: The owner builds a framed office with a door for about $3,500, takes photos, writes a job description, and sends both to the broker. The next policy rates her as clerical.
Frequently asked questions
Q: Can my bookkeeper qualify for a clerical workers comp classification?
Yes, in most states, if she does office work only, sits behind a barrier that keeps her away from the work, and leaves it only for occasional errands. Supervising the crew, outside sales, or physical work loses the category.
Q: Does a desk in the shop count as an office?
In most states, no. A desk in the same open room as the tools, the dust, and the vehicles is exposed to the work, so the barrier test is not met. A wall with a door fixes it.
Q: Can my bookkeeper work from home and still be clerical?
Usually yes, as long as the desk is away from where the work happens. A desk in the garage you store materials in does not count. In many states someone who works mostly from home is rated under a separate category priced about the same.
Q: What if my bookkeeper sometimes picks up parts or visits a job site?
Once in a while is fine. Every week is not. The rule allows only occasional time outside the office, and regular field errands move her payroll into the trade category.
Q: Can I split my bookkeeper's payroll between clerical and the field rate?
In most states, no. If she does non clerical work too, all of her payroll goes to the category where most of her work sits. Splitting by hours is only for categories properly on your policy, with time records.
Q: Can I get money back for past years if my bookkeeper was rated wrong?
Often, yes. A correction normally reaches back to the start of the policy it applies to. Whether it reaches earlier years depends on your state, the rule setting group, and the insurer.
