Hi farah Mo , 

Thanks for reaching out, it seems like there might be an incomplete step in your payroll setup that's preventing you from opening the payroll run. I recommend reviewing the setup process to ensure all steps are correctly completed. You can find a detailed guide on setting up your payroll module here: Sage Payroll Setup Guide. A summary is below:

1. Verify Payroll Setup:

   • Navigate to Setup > Settings > Payroll > Linked Accounts and ensure all fields have an account selected with your accountant's guidance.
   • Confirm that incomes are set up correctly for taxes, especially the vacation liability account.
   • Check that deductions and taxes are properly configured with the correct rates.

2. Add New Payroll Income:

   • Go to Setup > Settings > Payroll > Income and create a new income type, ensuring it's linked to the correct accounts.
   • Update the Employee Record to use the new income, marking the appropriate rate.

3. Create New Payroll Deduction:

   • Under Setup > Settings > Payroll > Deductions, create and configure a new deduction.
   • In the Employee Record, activate the new deduction and set the rate.

4. Configure Payroll Taxes:

   • In Setup > Settings > Payroll > Linked Accounts > Taxes, link the correct accounts for payroll taxes.
   • For Quebec employees, also link accounts for provincial taxes and contributions.
   • Taxes will calculate automatically in the paycheque screen if "calculate taxes automatically" is enabled.

5. Set Up Payroll Remittance:

   • Add Receiver General as a vendor if not already present.
   • In Setup > Settings > Payroll Remittance, link EI, CPP, and Tax to Receiver General.
   • Confirm remittance amounts via the General Ledger Report.

6. Create Employee Records:

   • Use the Employees icon to add and fill out details for each employee.

7. Process Paycheques:

   • Under the Paycheque icon, create and fill out paycheque details, then select Process.

If you've already followed these steps and the issue persists, please ensure that all payroll entries are complete and there are no active Payroll IDs causing conflicts. If the problem continues, our support team will be glad to assist further, connect with us through the Help and Chat options available within your Sage product.

Warm Regards,

Because you are getting an "History Mode" warning, it means you are still in the middle of setting up your company in Sage 50.

You cannot use the Payroll Cheque Run module until you complete the setup of the program because the Payroll Cheque Run module does not have a Manual Calculation mode, only Paycheques has that mode.

If your company file is completely set up and all opening balances are entered, then take a backup of your file and once that is completed, select the History Menu and Finish Entering History.  Follow the prompts.

Please make sure you have all the information to create T4's for your employees if your business was operating before using Sage 50, before you Finish History or your T4's for this year could be incorrect.

Opening balances also includes any customer or vendor invoice still owing at the date you start using Sage 50 and any balance in any account on your balance sheet or income statement.  There are also other parts to the file if you are using them that require opening balances.

Thank you
