Practical help:Keep invoices and expense records distinct
Comprehensive technical and procedural guide for self-employed professionals, independent contractors, and small business owners on contemporaneous expense tracking, deductible business expenses, and documentary proof standards.
United States tax law under Section 274(d) of the Internal Revenue Code strictly disallows deductions for business travel, gifts, and entertainment unless the taxpayer substantiates the expense with adequate contemporaneous records. IRS Publication 463 establishes the evidentiary standards that self-employed individuals, independent contractors (1099 recipients), and corporate employees must maintain.
A contemporaneous record is one recorded at or near the time of the expenditure. The IRS gives significantly higher probative weight to logs, diaries, and vouchers recorded while the taxpayer has full, immediate knowledge of each element of the expenditure. Reconstructing expense logs months later during an audit is frequently rejected by the tax court.
Under Treasury Regulation § 1.274-5(c)(2)(iii), documentary evidence (such as an itemized invoice, bill, or receipt) is required for any business expense of $75 or more, with two strict exceptions: (1) Lodging expenses require documentary evidence regardless of amount, and (2) Transportation charges where documentary evidence is not readily available (such as metered public transit). For items under $75, a detailed contemporaneous expense log stating date, amount, vendor, and business purpose fulfills statutory requirements.
Under IRS Publication 463, a contemporaneous expense log or account book serves as legal proof of elements such as date, location, amount, and business purpose. For expenses of $75 or more (and all lodging expenses regardless of amount), the IRS also requires documentary evidence (such as a canceled check, credit card statement, or formal receipt).
