Research Methodology

What we research (and what we don't)

Our guides are built primarily from:

• Primary government sources. IRS publications and forms, state Departments of Revenue, Secretary of State filing requirements, and agency guidance (e.g., SBA, DOL) take priority over any secondary summary of them.
• Statutes and official filings. Where a rule references a specific form, deadline, or statute, we link to the official source rather than paraphrasing from another blog.
• In-house operating experience. Our team works with US businesses on incorporation, bookkeeping, tax, and payroll daily; guides reflect patterns we actually see, not just published rules.

We deliberately exclude:

• Unverified claims copied from other websites without checking the underlying source.
• Generic, unreviewed AI-generated text presented as authoritative guidance.
• Personalized tax, legal, or financial advice; our content is educational, and specific situations should be reviewed with a qualified professional.

How we verify accuracy

Before a guide is published, we check it against four criteria:

• Source traceability. Every rate, deadline, threshold, or filing requirement should trace back to a primary or official source.
• Currency. Content reflects the current tax year and the latest known version of the relevant rule at time of publication.
• Jurisdictional scope. Federal, state, county, and city rules are called out separately rather than generalized, since compliance obligations vary by location.
• Plain-language clarity. A founder without an accounting background should be able to follow the guide and know what action to take next.

What disqualifies a guide from publishing

• A rate, deadline, or requirement that can't be traced to a primary or official source.
• Content built around a rule that has since changed, without an update.
• Advice framed as applying nationally when it's actually state- or city-specific.
• Promotional claims about FinStackk's own services presented without disclosure that they are FinStackk's services.

How we handle FinStackk's own products in our content

Some guides reference FinStackk's own incorporation, bookkeeping, tax, payroll, or cap table services where relevant to the topic. When they do, that's disclosed in context rather than presented as an independent third-party recommendation. The underlying rules, rates, and deadlines described in a guide hold regardless of which provider a reader ultimately uses.

How we keep this current

Tax rates, filing deadlines, and compliance requirements change, sometimes annually and sometimes mid-year. Guides tied to a specific tax year or filing deadline are reviewed as that year turns over, and we prioritize out-of-cycle updates whenever we're aware of a rate change, deadline shift, or new legislation (such as a federal tax reform bill or a state-level rule change) that affects something we've published.

Corrections policy

If you find an error in one of our guides (an outdated rate, a broken source link, a deadline that's changed), email support@finstackk.com with the article URL and what you believe is incorrect. Substantive corrections (anything affecting the accuracy of the guidance itself) are reflected with an updated publish date; minor corrections (typos, formatting, broken links) are fixed without a separate note.

Editorial independence

We don't accept payment from third parties to be named, recommended, or favorably described in our guides. Where a guide compares tools, forms, or approaches, the comparison reflects our own operating experience and publicly available information, not a sponsorship arrangement.

Who does this research

FinStackk was founded by operators who worked directly on accounting, tax, and compliance for US businesses before building the platform. Guides are researched and reviewed internally by our accounting, tax, and compliance team before publishing.

Guides that follow this methodology

This methodology applies across our entire knowledge base, including incorporation, bookkeeping, tax compliance, payroll, and equity management guides. If you'd like us to cover a specific topic or double-check a claim in an existing guide, reach out at support@finstackk.com.
