Background
Munib Ur Rehman founded National Tax Tools to address a gap in freely available tax resources. Most free tools were too simplified for real-world situations. Others were buried inside commercial platforms built to upsell paid software.
His focus has been building accurate, IRS-sourced calculators and reference guides for self-employed Americans: freelancers, independent contractors, consultants, and small business owners. Their tax situations are more complex than those of W-2 employees.
Role at National Tax Tools
Munib serves as the primary author for all content on National Tax Tools. His responsibilities include:
- Researching IRS publications, Revenue Procedures, and annual inflation adjustments
- Writing and maintaining all tax calculators, guides, and reference pages
- Coordinating the annual content review process with Nausheen Shahid
- Monitoring IRS guidance for mid-year updates that affect published content
- Maintaining editorial independence — no advertising relationships or sponsored content
Areas of Focus
National Tax Tools covers the topics most relevant to self-employed individuals and small business owners. That includes SE tax calculation, quarterly estimated payments and safe harbor rules, state refund tracking, key IRS filing deadlines, and 1099 income tax planning.
Editorial Philosophy
Munib's approach to content follows a strict sourcing hierarchy: IRS.gov and official state Department of Revenue websites are the only acceptable primary sources for tax rates, thresholds, and deadlines. Every substantive claim links to its original official source. Content that cannot be sourced to an official government publication is not published.
This approach reflects the high accuracy standards required for tax content, where even small errors can lead readers to underpay or overpay taxes. See the full Editorial Policy for details on the review and update process.
