Hi, Alicia. I'll help you with tracking the BC Increased Employment Incentive (IEI) in QuickBooks.
You can record the one-time tax credit as an income or a deposit. You can create an income account from the Chart of Accounts to track the credit. Otherwise, you may reach out to your accountant for additional assistance. They're experts in the accounting field and can advise you on the process. If you don't have an accountant, you can find one familiar with QuickBooks Online through this link: Find an Accountant.
