Disclaimer

Last Updated: March 26, 2026

The information and tools available on reversetax.cashluom.online are provided strictly on an "as is" and "as available" basis. We have built this tool with care and attention to accuracy, but it is essential that you understand its scope and limitations before relying on any output it produces.

1. Not Professional Financial or Tax Advice

Let us be direct about this: the Reverse Sales Tax Calculator is a math tool. It divides numbers using a standard formula. It does not interpret tax law, analyze your specific financial situation, or account for the many exceptions, exemptions, and special rules that exist across different states and jurisdictions.

The results generated by this calculator should never be treated as a substitute for advice from a qualified professional. If you are making decisions that affect your tax filings, business accounting, or financial planning, please consult with:

  • A Certified Public Accountant (CPA)
  • A licensed tax attorney
  • An enrolled agent authorized by the IRS
  • Your state's Department of Revenue for state-specific tax questions

We do not hold any professional license in accounting, tax preparation, financial planning, or legal advisory services. Nothing on this website should be interpreted as creating a professional-client relationship between you and Cashluom.

2. Accuracy of Information

We have taken great care to ensure the mathematical logic behind the calculator is correct. The reverse tax formula — Original Price = Total Price ÷ (1 + Tax Rate as decimal) — is a well-established and universally accepted method for extracting pre-tax amounts from tax-inclusive totals.

However, there are areas where accuracy depends on factors outside our control:

  • Tax rates change frequently. The state baseline rates in our dropdown are sourced from publicly available data and are accurate at the time they were last updated. County, city, and special district rates can change quarterly or even monthly in some jurisdictions. Always verify the current rate with your local tax authority before using a result for anything official.
  • Exemptions and special rules exist. Many states exempt groceries, prescription medicine, clothing, or other categories from sales tax. Some states have reduced rates for certain goods. Our calculator cannot know what product you are calculating for, so it applies the rate you choose to the entire amount.
  • Rounding conventions vary. Different jurisdictions may round tax amounts differently (some round up at 0.5 cents, others use bracket tables). Our calculator uses standard mathematical rounding to two decimal places, which may occasionally differ from the method your local authority uses.
  • Tax-inclusive vs. tax-exclusive pricing. Our calculator assumes the standard US model where sales tax is added on top of the listed price. A few localities or specific business contexts may use tax-inclusive pricing natively, which would change the calculation approach.

3. No Guarantees or Warranties

We provide this tool free of charge and without any warranties — express, implied, or statutory. Specifically, we disclaim any warranty of:

  • Merchantability: We do not warrant that the tool is suitable for any particular commercial purpose
  • Fitness for a particular purpose: We do not warrant that the results are appropriate for your specific use case, whether that is personal budgeting, business accounting, or tax filing
  • Accuracy or completeness: While the math is correct, the applicability of results to your real-world situation depends on many factors we cannot control
  • Uninterrupted availability: We do not guarantee the website will be available at all times. Server issues, maintenance, and hosting factors can cause temporary downtime

4. Limitation of Liability

To the maximum extent permitted by applicable law, Cashluom and its owners, developers, and contributors shall not be held liable for any damages whatsoever arising from the use of — or inability to use — this website or its tools. This includes but is not limited to:

  • Errors in tax calculations resulting from incorrect user input or outdated tax rates
  • Financial losses from business decisions influenced by calculator results
  • Penalties, fines, or interest resulting from inaccurate tax filings based on calculator output
  • Lost revenue or missed deadlines
  • Any indirect, incidental, special, or consequential damages

You acknowledge that the use of this tool is entirely at your own risk, and that you bear full responsibility for verifying the accuracy and appropriateness of any results before acting on them.

5. External Links

Our website may include links to third-party websites, such as state tax authority pages, educational resources, or reference tools. These links are provided for convenience and informational purposes. We do not control the content of external websites, and linking to them does not imply endorsement or responsibility for their content, privacy practices, or accuracy.

6. Use at Your Own Risk

Every time someone uses a free online tool for anything involving real money, they should ask themselves: "Have I double-checked this?" We built the Reverse Sales Tax Calculator to be as accurate and helpful as possible — and for the vast majority of everyday uses, it does the job perfectly well. But if the stakes are high (think: quarterly tax filings, audit preparation, large invoices), treat our output as a starting point, not the final word.

We are not liable for how you choose to use the numbers our tool generates. The responsibility for proper use rests entirely with you.

7. Updates to This Disclaimer

We may update this Disclaimer as needed to reflect changes in our tools, legal requirements, or best practices. The "Last Updated" date at the top of the page will always reflect when the most recent revision was made. We encourage you to review this page periodically.
