Editorial Standards

How we source, build, review, and maintain every calculator and article on SalaryCalcPro.

Tax and financial content has real-world consequences. A stale withholding rate, a missing deduction, or a mis-rounded bracket can lead users to wrong conclusions about their paycheck, their refund, or their budget. That is why SalaryCalcPro follows a documented editorial process for every calculator, rate table, and article — and why we update them on a published schedule rather than letting them drift out of date.

1. Sourcing by Jurisdiction

Every tax rate, contribution cap, withholding threshold, and formula on SalaryCalcPro is traceable to an official government source. We build primary tables from the following:

• United States — federal. Internal Revenue Service (IRS) publications (Publication 15 / 15-T for employer withholding, annual Rev. Proc. inflation adjustments, Form 1040 instructions). Social Security Administration for FICA limits.
• United States — state. Each state's department of revenue or tax commissioner (e.g., California FTB, New York DTF, Texas Comptroller). State unemployment and disability rates from each state's labor department.
• Costa Rica. Ministerio de Hacienda (income tax brackets), Ministerio de Trabajo y Seguridad Social — MTSS (labor law, aguinaldo, liquidaciones), Caja Costarricense de Seguro Social — CCSS (social-security contributions).
• Mexico. Servicio de Administración Tributaria — SAT (ISR tables, subsidio), Instituto Mexicano del Seguro Social — IMSS and INFONAVIT.
• Colombia. Dirección de Impuestos y Aduanas Nacionales — DIAN, Ministerio del Trabajo.
• Spain. Agencia Estatal de Administración Tributaria — AEAT, Seguridad Social.

We do not use consumer finance blogs, forums, or AI-generated tables as a primary source for tax rates. When official sources publish tables in non-machine-readable formats (PDF, scanned bulletins), we transcribe them manually, cross-check the transcription against a second official publication where possible, and retain the source PDF in our editorial archive so we can audit any figure on request.

2. Review Process

Every tax-related article and every update to a tax calculator passes a three-stage review before going live:

1. Source capture. The researcher saves the official source (URL, effective date, publication ID) alongside the draft. A claim without a source cannot be published.
2. Numerical cross-check. A second editor independently reconstructs the brackets, thresholds, or formula from the source and confirms the calculator matches. Unit checks (annual vs monthly, gross vs taxable, MXN vs USD) are mandatory.
3. Tax / labor review. A reviewer with a background in tax preparation or labor-law compliance for the jurisdiction in question reads the draft, flags anything that conflicts with current practice, and signs off on publication.

3. Reviewer Credentials

Our editorial team includes reviewers with backgrounds in tax preparation, accounting, and labor-law compliance. Reviewers are identified by name on each article they approve. We do not use vague “reviewed by an expert” labels. Reviewers who hold formal professional credentials (CPA, CFP, tax attorney, labor-law specialist) describe those credentials on the , and reviewers without formal credentials describe their relevant professional experience.

Reviewers with a commercial conflict on a specific topic (e.g., a reviewer who consults for a company whose product is being compared) recuse themselves.

4. Update Cadence

Tax and labor law move on calendars that differ by jurisdiction. We address this with a published update schedule:

• US federal tax brackets, standard deduction, FICA limits. Updated after the IRS publishes the annual Rev. Proc. adjustments (typically late Q4), effective January 1.
• US state tax tables. Updated as each state publishes the new year's brackets. Target: published within 14 days of each state's official release.
• Costa Rica (MTSS/Hacienda/CCSS). Reviewed annually, and immediately when MTSS publishes revised salarios mínimos, when Hacienda publishes new income-tax brackets, or when CCSS adjusts contribution rates.
• Mexico (SAT/IMSS). Reviewed annually in January (SAT tables), and immediately on any IMSS contribution-rate change.
• Colombia (DIAN) and Spain (AEAT). Reviewed annually, and immediately on any mid-year regulatory change.
• Investment and credit calculators. Formulas reviewed annually (interest compounding, amortization schedules). Default assumptions (rate ranges, inflation figures) refreshed quarterly.

Every calculator and article displays a Last updated date. When the date falls behind the above targets, the item is flagged in our CMS and scheduled for review.

5. Correction Policy

We take corrections seriously. If a calculator or article contains a factual error or an outdated rate:

1. Email our contact form with the URL and a description of the error. A link to the official source that contradicts our figure helps us act fastest.
2. Tax-table errors and formula bugs are evaluated within 2 business days.
3. If we confirm the error, the calculator or article is updated and a dated correction note is added at the bottom of the article (or at the top of the calculator's “notes” section) explaining what changed. Material corrections also trigger a refreshed Last updated date.
4. If we cannot confirm the error, we respond explaining our reasoning and the official source we relied on.

6. Conflicts of Interest & Independence

SalaryCalcPro does not sell tax-preparation services, investment products, or financial advice. We do not accept payment for editorial coverage. We do not publish sponsored content disguised as articles. Advertising (Google AdSense or other ad networks, if enabled) is contextual and does not influence editorial decisions.

If an article contains affiliate links (e.g., to a product referenced in a comparison), the article discloses this at the top. Reviewers with a commercial relationship to a product under discussion recuse themselves from that article.

7. AI Assistance

We use AI tools for research, draft outlining, translation, and copy-editing. We do not use AI to generate tax rates, brackets, or formulas. Every published figure is traceable to an official human-curated source. AI-assisted drafts go through the full source-capture, cross-check, and review process above.

8. User-Generated Content

SalaryCalcPro does not host comments, forums, or user-submitted articles. Calculator inputs are processed entirely in the user's browser and are never transmitted to our servers.

9. Plain Language

Our target reading level is approximately US grade 9. Tax terminology is defined on first use. We prefer concrete numbers ("the 2026 standard deduction is $15,000 for single filers") to vague language. Every tax calculator explains which jurisdiction it models, which year its tables reflect, and what assumptions it makes.
