Section directory

Browse the full tax library by workflow, not by loose keyword sprawl.

This page is the site map for TaxTermsLexicon.com. Use it when you want the whole structure: income calculation, forms, deductions, credits, dependents, withholding, payroll tax, business tax, entity treatment, basis, IRS follow-up, and compliance.

If you already know the document or problem in front of you, Start Here is usually faster. If you want to understand how the site is laid out, stay here.

Browse by workflow stage first

These lanes are the fastest way to enter the right part of the library when the reader knows the kind of tax task but not the section name.

Filing and Core Calculation

Use these sections when the question is what gets filed, what counts as income, and how the main calculation moves toward tax due or refund.

Credits, Household Context, and Payment Timing

Use these sections when eligibility, filing status, dependents, withholding, or estimated payments are driving the outcome.

Payroll, Business, and Entity Workflow

Use these sections when income is being withheld, reported through business forms, or shaped by entity-level versus pass-through tax treatment.

Basis, Notices, and Enforcement Follow-Up

Use these sections when the issue is asset sales, IRS correspondence, account records, penalties, collection consequences, or dispute steps.

Top-level section directory

Each section card names the cluster, explains what it is for, and points to a good first page under it.

Income Tax Basics

Gross income, AGI, taxable income, tax brackets, marginal rates, effective rates, and liability terms.

Tax Forms and Filing

The return, schedules, wage forms, entity returns, and information documents that carry tax reporting forward.

Deductions and Adjustments

Terms that reduce income before tax is calculated or decide whether to use Schedule A.

Tax Credits

Credits that reduce tax directly and often depend on income, family facts, or refundability rules.

Filing Status and Dependents

Who qualifies as a dependent and which household status governs the return.

Withholding and Estimated Tax

How tax gets paid during the year instead of all at once when the return is filed.

Payroll Tax

FICA, Social Security tax, Medicare tax, and self-employment tax for wage and business readers.

Business Tax

Business deductions and recovery rules that shape how business property and expenses are treated.

Entity Taxation

Terms that explain whether income is taxed at the entity level or passed through to owners through entity-return reporting.

Capital Gains and Basis

Cost basis, adjusted basis, gain or loss, holding periods, Schedule D workflow, and wash-sale limits.

IRS Process and Notices

What happens after filing when the IRS sends a notice, uses account records, raises an identity issue, or moves the case forward.

Penalties and Compliance

The language of missed deadlines, unpaid balances, liens, levies, and other consequence terms.

Audit and Disputes

Audit-related vocabulary and dispute concepts readers meet when a return moves into review or challenge.

Additional specialty sections

These sections matter when the tax question clearly sits outside the core federal filing chain but still belongs in a serious tax reference.

State and Local Tax

Ownership taxes and transaction taxes that readers often confuse with federal deduction or filing terms.

Property Tax

International Tax

Cross-border terms that help readers separate income exclusions from later foreign-tax credits.

Foreign Earned Income Exclusion

Estate and Gift Tax

Transfer-tax vocabulary for lifetime gifts and wealth transfer at death outside annual income-tax filing.

Need to report a gap?
