Part of the series: 10 Small Business Tax Mistakes (Based on IRS Guidance)
Proper documentation is an important part of maintaining accurate business records.
IRS Publication 583 and IRS Publication 463 explain that taxpayers must keep records that support the income and expenses reported on a tax return. Certain expenses, such as travel, meals, and vehicle use, have specific substantiation requirements.
When documentation is incomplete or missing, it can be difficult to verify that expenses qualify as deductions.
Why This Happens
Many small business owners keep receipts and records informally or only review them when preparing taxes.
Over time, receipts may be misplaced, digital records may not be saved, or the business purpose of an expense may not be clearly documented.
Without consistent documentation practices, important supporting records can be lost.
IRS Requirements
IRS Publication 583 explains that businesses must maintain records that support the amounts reported on a tax return.
IRS Publication 463 provides additional guidance for documenting certain expenses, including travel, meals, and vehicle use.
These records typically include receipts, invoices, logs, or other documentation that verifies the amount, date, and business purpose of an expense.
Why This Creates Problems
Without proper documentation, expenses may be difficult to verify or support.
- Unverified deductions
If records cannot confirm that an expense was business-related, the deduction may not qualify.
- Incomplete records
Missing receipts or supporting documents can make financial records less reliable.
- Difficulty supporting tax filings
If documentation is requested to support reported expenses, missing records can make verification more challenging.
Best Practices
Maintaining organized documentation helps ensure that business expenses can be properly supported.
Keeping digital copies of receipts, invoices, and supporting records can make it easier to maintain documentation throughout the year.
Recording the business purpose of expenses at the time they occur also helps clarify how the expense relates to business activity.
Steps to Take
- Keep receipts, invoices, and other supporting documents for business expenses.
- Store digital copies of records to reduce the risk of lost paperwork.
- Document the business purpose of expenses when they occur.
- Review records regularly to confirm that documentation is complete.
