Situation-first routing
Use this page when you know the form, notice, paycheck issue, or filing decision in front of you, but you do not yet know the exact tax term you need.
Most readers should begin from the real trigger. Open one page first, confirm the concept, then follow the related-term trail instead of jumping randomly across the whole site.
Each card is an entry path for a real workflow trigger, not just another generic topic label.
Start with the return form itself, then move into the calculation terms that determine how much tax is owed or refunded.
Start with the document you received, then connect it to the withholding or payroll concepts that explain the numbers.
Use these pages when the question is whether something lowers income, lowers tax directly, or depends on household status.
Use the household pages when the issue is who can be claimed, which filing status applies, or why a credit rule changed.
Use these pages when the issue is no longer just wage income and now includes direct business reporting, entity returns, owner-level pass-through documents, or depreciation.
Use the basis and gain pages when the issue is sale proceeds, basis, Schedule D reporting, holding period, or whether a loss is limited or deferred.
Use these pages when the tax issue is timing and payment method rather than the final calculation on the return.
Use these pages when the issue is a notice, a mismatch, an account record question, a filing-security problem, or the next asserted-tax step.
Use Library when you want the site organized by tax workflow and topic cluster instead of by situation.
Open LibraryUse the support pages when the real question is what the site covers, how it is edited, or whether it fits your use case.
Read the FAQBroken links, missing tax terms, and off-domain residue belong on the support pages rather than in article comments.
