Editorial Policy & Research Methodology

Last updated: June 17, 2026

1. Our Authority Model: Math-First Strategy

Unlike traditional personal finance websites that rely on generic "high-level" summaries or regurgitated SEO articles, Indie Tax Stack operates on a developer-led, math-first authority model. We believe that a tax strategy is only as good as the calculations behind it. Our workflow is designed to ensure maximum transparency and technical accuracy:

  1. Research: Analyze primary IRS source code, forms, publications, and Treasury guidance.
  2. Build Calculator: Implement the mathematical models inside interactive client-side simulators.
  3. Write Article: Explain the underlying IRS mechanics, limitations, and planning concepts in plain English.
  4. Verify Formulas: Test calculator edge cases and outputs against published IRS examples, instructions, and tax court rulings.
  5. Ship Tool: Make the code open, free, and executable directly in the user's browser.

2. How We Research

All tax planning concepts and calculations are grounded in official tax sources. We do not use unverified blogs, secondary summaries, or AI-generated text. Our core reference materials include:

  • IRS Publications: Primary guides including Pub 535 (Business Expenses), Pub 334 (Tax Guide for Small Business), Pub 544 (Sales and Other Dispositions of Assets), and Pub 505 (Tax Withholding and Estimated Tax).
  • IRS Form Instructions: Official instructions for Form 1120-S (S-Corporations), Schedule C (Sole Proprietors), Schedule SE (Self-Employment Tax), and Form 8824 (Like-Kind Exchanges).
  • Treasury Regulations: Code Sections and Treasury regulations, such as Treas. Reg. § 1.1031 for real estate tax deferrals and IRC § 199A for the Qualified Business Income (QBI) deduction.
  • Tax Court Precedents: Relevant judicial findings (e.g., David E. Watson, P.C. v. United States) to benchmark reasonable compensation guidelines.

3. Formula Verification & Testing

Before any calculator is published or updated, its underlying engine is subjected to regression testing against official IRS examples. For instance:

  • The S-Corp Optimizer is tested using the exact Schedule SE and Schedule C worksheets to verify self-employment tax calculations down to the dollar, including the phase-out rules of the § 199A QBI deduction.
  • The 1031 Exchange Wizard replicates realized gain, recognized gain, and replacement basis formulas outlined under Treas. Reg. § 1.1031.
  • The Capital Gains Simulator is tested against the Schedule D tax worksheets to ensure short-term and long-term tax brackets are stacked correctly alongside the 3.8% Net Investment Income Tax (NIIT) thresholds.
  • The IRS Audit Risk Matrix uses public audit selection and Discriminant Income Function (DIF) scoring guidelines to flag standard statistical anomalies.

4. Client-Side Integrity & Privacy

We believe user privacy is critical to trust. No numbers, values, or financial details entered into Indie Tax Stack calculators are ever transmitted to or stored on our servers. All processing is performed locally in your browser using pure client-side JavaScript. You can verify this at any time by running the tools in offline mode or reviewing the browser's network tab.

5. Updates for Tax Law Changes

Tax rules, brackets, standard deductions, and phase-out thresholds change annually due to inflation indexation. Our models are built around the 2026 tax brackets and IRS adjustments. We monitor the IRS Bulletin and update the mathematical models as soon as official inflation adjustments are published for subsequent tax years.

6. Disclaimer

While we strive for absolute mathematical precision, Indie Tax Stack does not provide official tax, legal, or financial advice. All outputs are estimates intended for educational planning purposes only. For more details, please see our dedicated Disclaimer page.
