Key filing rhythms

Keep the recurring deadlines visible before they become urgent.

These are general filing rhythms for common calendar-year business obligations. Entity type, filing frequency, extensions, weekends, holidays and special relief can change the exact due date.

Accounting & tax glossary

Plain-English definitions for the terms that affect the work.

This glossary stays on one useful page rather than creating a thin URL for every term. Definitions are intentionally practical and should be read in the context of the business and filing involved.

Reconciliation

Comparing the accounting balance with an outside source—such as a bank or credit-card statement—and resolving the differences.

Chart of accounts

The structured list of asset, liability, equity, revenue and expense accounts used to classify transactions in the books.

Accrual basis

An accounting method that generally records revenue when earned and expenses when incurred, rather than only when cash moves.

Taxable sales

Sales included in the portion of Texas sales activity that is subject to sales and use tax after applying the relevant rules and exemptions.

Use tax

A complementary Texas tax that can apply when taxable items are bought without the full Texas sales tax and are used, stored or consumed in Texas.

Nexus

A connection with a state that can create a tax registration, collection or filing obligation under the rules for that tax.

PIR / OIR

Texas franchise-tax information reports used for different entity types: the Public Information Report and Ownership Information Report.

Catch-up vs. cleanup

In-depth guides

Ten focused resources for the questions Texas business owners actually ask.

Each guide has one dominant intent, links back to the relevant service when appropriate and uses official sources for tax rules that can change.
