Check with your accountant before running the final yearly financials. There is a good chance that he or she will give you some year-end entries (depreciation, etc.).
To review the year's activities, your accountant will need, at minimum, your Trial Balance [Summary] report, your year-end Balance Sheet, and your year-end Profit & Loss.
Here's our recommended list of annual reports:
Profit & Loss
Profit & Loss [with Last Year]
Balance Sheet
Balance Sheet [Last Year Analysis]
Debtors Reconciliation [Summary]
Creditors Reconciliation [Summary]
Trial Balance
Note: Depending upon the amount of tax you withhold from your employee paycheques, you may be required to report and/or remit money to the government according to the schedule sent to you by both national and local athorities. For help in preparing remittance reports, see:
Payroll Tax Reporting and Deposits
Note: Once you settle on the list of reports you like to run every month, consider creating a report batch for them. Refer to What's a Report Batch? for more information.
