Sharpe CPA / For CPAs / Terms of use and sources
Every free tool on this site is built from public standards and regulations. Here is what you agree to when you use one, and the public source behind each.
Use at your own risk.
All of the work a CPA performs is subject to that person’s or firm’s professional judgment. These tools do not make that judgment for you and are not a substitute for it.
Do your own research, and verify that the checklist or protocol you are using is valid and up to date. Standards, regulations and IRS procedures change, and a citation that was right when a page was written may not be right when you read it.
The tools, pages, checklists, templates, calculations and downloads are provided “as is” and “as available”, without warranty of any kind, express or implied, including any warranty of accuracy, completeness, currency, fitness for a particular purpose or non-infringement. They may contain errors or omissions.
To the fullest extent permitted by law, James D. Sharpe, CPA and Sharpe CPA will not be liable for any loss or damage of any kind — direct, indirect, incidental, consequential or otherwise, including lost fees, regulatory or peer review findings, penalties, or claims by clients or third parties — arising from the use of, or reliance on, any free tool or its output.
Nothing on these pages is accounting, auditing, legal or tax advice, and using a tool does not create a professional relationship. The output is a starting point. The CPA or firm that signs a report, issues a financial statement, files a return or represents a taxpayer is solely responsible for it, and for complying with the AICPA, PCAOB, SEC, IRS and state board rules that apply.
Each page cites the paragraphs it was built from. Check those citations against the current text of the FASB Codification, the auditing and review standards, the Internal Revenue Code, the regulations and the Internal Revenue Manual before relying on them. The pages were last reviewed in September 2026.
The tools run in your browser. Trial balances, bank statements, customer lists and figures you enter are processed on your computer and are not uploaded to this site. Files you download are yours to keep and protect.
Links go to public sources maintained by others; their content is theirs. FASB, AICPA, PCAOB, SEC and IRS are named only to identify the sources. This site is not affiliated with or endorsed by any of them.
