Nebraska-Specific Tax Requirements
Nebraska has a graduated individual income tax with rates from 2.46% to 5.84%. The corporate income tax is also graduated, ranging from 5.58% to 7.25% based on taxable income. Nebraska allows a partial deduction for federal income taxes paid, which reduces the effective state tax rate. There is no franchise tax or gross receipts tax.
Nebraska's state sales tax rate is 5.5% with local option taxes adding up to 2%, bringing combined rates to 7.5% in some areas. Groceries are exempt from state sales tax but may be subject to local taxes. The economic nexus threshold for remote sellers is $100,000 in sales or 200 transactions. Businesses file sales tax through Nebraska Online Filing.
Biennial reports are filed with the Nebraska Secretary of State every two years (in even-numbered years for most entities) for a $26 fee. Nebraska requires employers to withhold income tax and file monthly or quarterly based on payroll size. Nebraska has relatively straightforward tax compliance compared to many states.
