471-070-3160 Employer Size: Method to Determine Number of Employees Employed by an Employer (1) Employer size is based on the average of the employer’s monthly employee counts as defined in OAR 471-070-3150(2). (a) An employer’s employee count is the number of employees on the employer’s payroll for the pay period that includes the 12th of the month, and is the sum of: (A) The number of employees in Oregon; and (B) The number of out-of-state employees. (b) The employee count may not include any replacement employees hired to temporarily replace eligible employees during periods of Paid Leave Oregon leave. Example 1: ABC Construction has weekly pay periods covering Sunday to Saturday. For October 2022, the 12th of the month is included within the pay period covering October 9th to October 15th. ABC Construction paid 15 employees in Oregon and 8 employees in Washington during the pay period covering October 9th to October 15th. ABC Construction’s employee count for October 2022 is 23 employees (15 Oregon employees + 8 out-of-state employees). Example 2: Suzana Vucic, a domestic employer, has monthly pay periods. For April 2024, the 12th of the month is included within the pay period covering April 1st to April 30th. Suzana Vucic paid two employees in Oregon, including one employee temporarily hired to replace an employee during a period of Paid Leave Oregon leave, and 0 employees out-of-state during the pay period covering April 1st to April 30th. Suzana Vucic’s employee count for April 2024 is 1 employee (2 Oregon employees + 0 out-of-state employees - 1 replacement worker). Example 3: Top Notch Temps has biweekly pay periods. The employer is based in Idaho and opened an office in Oregon in September 2024. For July 2024, the 12th of the month is included within the pay period covering July 12th to 26th. Top Notch Temps was not operating in Oregon during the pay period covering July 12th to 26th and had no Oregon employees or replacement workers and had 40 employees working in Idaho. Top Notice Temps’ employee count for July 2024 is 40 employees (0 Oregon employees + 40 out-of-state employees - 0 replacement workers). (2) Employer size is not rounded. (3) Employer size shall be determined annually for each calendar year based on the average of the monthly employee counts from January to December in the previous calendar year. Example 4: Abraham’s Furniture Depot has the following employee counts for 2022: January - 25; February - 26; March - 26; April - 24; May - 23; June - 22; July - 24; August - 25; September; 26; October - 26; November - 26; December - 24. The monthly employee counts are added together and then divided by 12 months to arrive at the average employee count of 24.75 [(25+26+26+24+23+22+24+25+26+26+26+24 = 297) / 12 months = 24.75]. Abraham’s Furniture Depot is a small employer for all of calendar year 2023. Example 5: Sally’s Tree Farms has the following employee counts for 2025: January - 15; February - 15; March - 14; April - 16; May - 10; June - 12; July - 20; August - 40; September - 45; October - 50; November - 55; December - 50. The employee counts are added together and then divided by 12 months to arrive at the average employee count of 28.5 [(15+15+14+16+10+12+20+40+45+50+55+50) = 342 / 12 months = 28.5]. Sally’s Tree Farms is a large employer for all of calendar year 2026. Example 6: Reliable Transport has locations in California and Nevada and starts operating in Oregon in September 2026. The employee counts for 2026, which cover for the entire year even though Reliable Transport did not start operating in Oregon until September because Reliable Transport operated out-of-state, are: January - 20; February - 20; March - 21; April - 20; May - 20; June - 19; July - 20; August - 21; September - 30; October - 30; November - 31; December - 30. The employee counts are added together and then divided by 12 months to arrive at the average employee count of 23.5 [(20+20+21+20+20+19+20+21+30+30+31+30) = 282 / 12 months = 23.5]. Reliable Transport is a small employer for all of calendar year 2027. (4) For new employers, employer size shall be determined quarterly until the employer has operated for an entire calendar year. At the end of each quarter, the average monthly employee counts from the preceding 12 months shall be used to determine the employer size for the quarter. Example 7: Cafe Senad is a new business only in Oregon that started operating in May 2027. Cafe Senad’s first quarterly payroll report is filed for the second quarter of 2027 (April to June). Employer size for the 2027 second quarter is based on the average employee counts for July 2026 to June 2027. Cafe Senad’s employee counts are: May 2027 - 25; June 2027 - 30; and 0 for all other months. The employee counts are added together and then divided by 12 months to arrive at the average employee count of 4.58 [(0+0+0+0+0+0+0+0+0+0+25+30) = 55 / 12 months = 4.58]. Cafe Senad is a small employer for the second quarter of 2027 and is not required to pay the employer contributions for the second quarter. Employer size for the 2027 third quarter is based on the average employee counts for October 2026 to September 2027. Cafe Senad’s employee counts are: May - 25; June - 30; July - 42; August - 44; September - 44; and 0 for all other months. The employee counts are added together and then divided by 12 months to arrive at the average employee count of 15.41 [(0+0+0+0+0+0+0+25+30+42+44+44) = 185 / 12 months = 15.41]. Cafe Senad is a small employer for the third quarter of 2027 and is not required to pay the employer contributions for the third quarter. Employer size for the 2027 fourth quarter is based on the average employee counts for January to December 2027. Cafe Senad’s employee counts are: May - 25; June - 30; July - 42; August - 44; September - 44; October - 50; November - 52; December - 55; and 0 for all other months. The employee counts are added together and then divided by 12 months to arrive at the average employee count of 28.5 [(0+0+0+0+25+30+42+44+44+50+52+55) = 342 / 12 months = 28.5]. Cafe Senad is a large employer for the fourth quarter 4 of 2027 and must pay the employer contributions for the fourth quarter.
