Taxpayers and business owners from Oklahoma need to know about Oklahoma state and local tax resources, and Business.com is here to help. Because state tax codes are updated and modified annually, people who do their own taxes, or those who run businesses, need to stay informed about the changes. The state of Oklahoma's official Web site is a great place to begin your search for information. The Web site's tax resources include downloadable forms, tax news, accountant verification, income tax assistance, and business filing information. The Web site also links to the federal IRS Web site for further information. In addition to the state Web site, many online tax service providers, such as H&R Block and TurboTax, can help you file returns and answer your questions. Information about local taxes can be slightly harder to find, but the Small Business Association exists primarily to help business owners; determining local tax obligations is one service that the SBA offers. Additionally, the Oklahoma Tax Commission has information for retailers and vendors regarding sales and use tax, tax rates, and tax liability. Oklahoma state and local tax resources are all over the Web, with options as varied as Oklahoma's local tax codes. Learn more by checking out the links here.
