## Determine Your Obligation Assessment

For the convenience of our employer customers, below are instructions to help you figure your 2017 obligation assessment.

**The 2017 rates are as follows:**

- OA ratio = 0.187277
- Base assessment = $63.00
- Taxable wage base=$9,000

The * example* calculation below is based on a fictional employer with a 2017 tax rate of 10.30% and 1,500 employees.

**Instructions:**

- Divide your tax rate (10.3) by 100. The result should be 0.103.
- Next, multiply 0.103 by the OA Ratio of 0.187277 (0.103 X 0,187277). Did you get 0.0192895? Good, that’s correct. Jot this number down.
- Now divide the Base Assessment by the Taxable Wage Base (63/9000). You should get 0.007. Next, add this number to the number you saved above and multiply the result by 100. (0.0192895 + 0.007 X 100). If you get 2.62895, you’re right. Always round up this number to the next hundredths of a percent. So now you should have 2.63.
**This is your 2017 OA Rate (2.63%).** - To obtain your
**cost per employee**, multiply this example’s OA Rate of 2.64 by the taxable wage base of $9,000. You should get a cost per employee of $236.70. - To obtain the
**total cost for the example employer**, enter the cost per employee of $236.70 and multiply it by the number of employees, which is 1,500 in this example. You should get $355,050 as the total cost for the example employer.

**Example Results Summary:**

- OA Rate = 2.63
- Cost Per Employee = $236.70
- Total Cost For Employer = $355,050

*Since most employers qualified for the $9,000 taxable wage base, this was used in the calculation instead of the higher taxable wage base of $9,500.
