Common mistakes
- Combining employment increases from different periods. A qualifying increase must occur in a single reporting period. You may not combine two or more periods to reach a qualifying employment level. A period is assumed to be a full fiscal or calendar year.
- Treating increases and decreases the same way. A current-year employment decrease on line 7 reduces the number of eligible new jobs on line 17 for that year. An employment increase is delayed a year.
- Leaving out required attachments. Attach the new-jobs schedule, Form 83-450 and Form 83-401 as directed.
