Key Takeaways
- Accounting errors are mistakes made during journalizing, posting, or totaling transactions, often classified into one-sided and two-sided types.
- One-sided errors affect only one account (like partial omission or totalling mistakes) and cause a trial balance difference, usually corrected through the suspense account before final statements.
- Two-sided errors, such as principles, complete omissions, or compensating errors, affect two or more accounts but balance both sides equally, leaving the trial balance unaffected and rectified through journal entries.
- Errors of omission involve missed entries
- Commission errors arise from wrong postings or amounts
- Principle errors break accounting rules by misclassifying items
- Compensating errors cancel each other out.
