Calcora Editorial

Editorial team & methodology

Every calculator and article on Calcora is built and reviewed under one documented process, led by founder Hassan Ahmed, using primary IRS, SSA, state revenue, and CRA sources. This page explains exactly how that works.

Who we are

Calcora is built and maintained by Hassan Ahmed, a software developer and the site's founder. He writes the calculator code, encodes each year's tax tables from the primary documents, and reviews the figures against the published sources before anything goes live. His profile is on the About page.

Calcora Editorial Team is the byline used on articles and calculator pages. It means the content was researched, built and reviewed under the process on this page, with every tax figure traced to a cited source and a recorded verification date. It is not a claim that a separate group of credentialed editors exists.

Hassan Ahmed is not a licensed CPA, CFP, EA, or attorney, and no one on Calcora is presented as one unless that credential is stated on this page. When we cite tax law or IRS regulation, we link directly to the primary source so readers can verify the rule themselves.

How we build a calculator

Source the data. We pull tax brackets, standard deductions, wage caps, and contribution limits from primary publications: IRS Revenue Procedures, state revenue authority bulletins, the SSA wage base announcement, and the Federal Reserve H.15 release. We record the publication URL and date in the underlying data file.
Encode the math. Brackets and formulas are encoded as data, not hard-coded constants. Each calculator runs the same progressive math you would do by hand, then shows the bracket-by-bracket breakdown so you can verify it.
Cross-check against an independent run. For tax calculators, we cross-check at least three salary points (entry, mid, high) against the official IRS tax tables or an established second source before publishing.
Cite and date.Every calculator displays a "Last verified" date and a link to the official source it draws from.

Update cadence

Federal tax data: reviewed when the IRS publishes the annual Revenue Procedure (typically October/November for the following tax year), and again in January after final SSA wage-base figures.
State tax data: reviewed annually by January 31, plus mid-year when a state announces a bracket or rate change.
Mortgage and loan calculators: formula-based, no time-sensitive data embedded. Default-rate suggestions are reviewed quarterly against Freddie Mac PMMS.
Articles:updated when a cited rule, threshold, or rate changes. We display both a publish date and a "Last reviewed" date on every post.

Our sources

Internal Revenue Service (IRS): federal brackets, standard deductions, contribution limits, Revenue Procedures.
Social Security Administration (SSA): annual wage base announcements for FICA.
State revenue departments (e.g. California FTB, NY Department of Taxation and Finance): state brackets, standard deductions, and credits.
Federal Reserve H.15 and Freddie Mac PMMS: reference interest rates.
Canada Revenue Agency (CRA) and provincial finance ministries: for the Canada cluster (currently de-emphasized while we focus on the US site).

Corrections policy

If you find a calculator result that disagrees with the cited source, please email us via the contact page with the input values and the result you expected. We aim to investigate within five business days. When we correct a calculator or article:

We update the underlying data file and republish the page.
We bump the "Last verified" / "Last reviewed" date.
For material errors (a wrong bracket rate, wage cap, or contribution limit), we add a dated correction note at the bottom of the affected article.

Editorial independence

We do not accept payment for favorable calculator results, biased recommendations, or content placement. Where affiliate links appear (for example to lender or brokerage comparison tools), they are disclosed on the relevant page and never influence the math, the cited source, or the conclusions.

Calcora is not a registered investment advisor, tax preparer, or law firm. We publish educational tools. For decisions affecting your finances, consult a licensed CPA, CFP, EA, or attorney.
