What a different classification would cost
ACC assigns your CU from your declared business activity, so a business doing more than one thing can reasonably sit in more than one unit — and the choice is not cost-neutral. Within Mining the levy runs from $0.22 (CU 12000, Oil and gas extraction) to $1.00 (CU 15200, Mining support services (not elsewhere classified)) — $780.00 a year apart on $100,000 of liable earnings. These are the Mining units closest to CU 13140 on a different rate:
| Classification unit | Rate | vs CU 13140 on $100,000 |
|---|---|---|
| CU 12000 Oil and gas extraction | $0.22 | −$780.00 a year |
