Who publishes these guides?
Comped publishes resources for people who buy and sell trading cards. Patrick Manfra is Comped's founder and CEO. A founder byline identifies the author; it does not imply a CPA, attorney or enrolled-agent credential.
Comped sells bookkeeping software. Our guides and product links have that commercial context. We are not a CPA firm, and the website does not file your tax returns.
How should I use the sources?
Follow the primary-source links beside a rule or in a page's source list. Federal tax questions refer to IRS guidance, statutes and regulations; state questions refer to the relevant state agencies. A rule for one jurisdiction is not a rule for every show.
Research pages explain their assumptions and provide source material or downloadable data where available. Examples are illustrations, not claims about a particular vendor's results.
What do the dates mean?
A source-check date describes when the cited material was checked for that guide. An updated date can also reflect changes to explanations, links or page structure. Updating the sitemap or design does not mean that every tax rule was reviewed again.
Check the tax year and effective date before using a number. A 2026 figure should not be assumed to apply to a 2025 return or a later tax year.
Is this professionally reviewed tax advice?
Do not assume a guide has been reviewed by a licensed tax professional unless it explicitly names that reviewer and their role. General education cannot establish your business classification, accounting method, filing obligations or eligibility for a deduction.
Calculators depend on their stated inputs and assumptions. Use them to explore an estimate, then have a qualified professional evaluate the full facts of your situation.
How is AI used?
AI tools assist with research, drafting, site development and technical checks. They can make mistakes. Citations, dated assumptions and a way to report errors are part of making that assistance inspectable; they are not a guarantee of accuracy.
How do I report a correction?
Email pat@graded.world with the page URL, the passage at issue and an official source if available. Avoid including tax returns, account numbers or other sensitive financial documents.
