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 Statement report
Profit & Loss [With Last Year] report
Balance Sheet report
Balance Sheet [Last Year Analysis] report
Receivables Reconciliation [Summary] report
Payables Reconciliation [Summary] report
Summary Trial Balance report
Detail Trial Balance report
Note: Depending upon the amount of tax you withhold from your employee paychecks, 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 authorities. 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.
