If you’re contemplating moving your organization from cash accounting to accrual accounting, or to a hybrid method that combines cash, accrual and special methods of accounting, refer to IRS Publication 538 and Form 3115 for further guidance.
The company designation of 'accrual' or 'cash' basis only refers to the type of reporting and how your sales tax is collected. You don't have to change transaction entries, but you do need to set your sales tax preferences correctly. If you collect sales tax, the reporting method must be configured correctly in your company preferences. For cash basis accounts, set your tax to track as of the payment date.
There are three types of reports that most companies use – detail, summary and sales tax liability. Summary and sales tax liability reports can be configured for cash accounts, or accrual accounts, in the default configuration. Detail reports must be manually configured each time you run the report.
