Most states tax at least some types of business income derived from the state. As a rule, the details of how income from a specific business is taxed depend in part on the business's legal form. In most states, corporations are subject to a corporate income tax, while income from pass-through entities such as S corporations, limited liability companies (LLCs), partnerships, and sole proprietorships is subject to a state's tax on personal income. Tax rates for both corporate income and personal income vary widely among states. Corporate rates, which most often are flat regardless of the amount of income, generally range from roughly 4% to 10%. Personal rates, which generally vary depending on the amount of income, can range from 0% (for small amounts of taxable income) to around 9% or more in some states.

Currently, six statesNevada, Ohio, South Dakota, Texas, Washington, and Wyomingdon't have a corporate income tax. However, four of those statesNevada, Ohio, Texas, and Washingtondo have some form of gross receipts tax on corporations. Moreover, five of those statesNevada, South Dakota, Texas, Washington, and Wyomingas well as Alaska, Florida, and Tennessee currently have no personal income tax. Individuals in New Hampshire are only taxed on interest and dividend income.

Apart from taxing business income through a corporate income tax or a personal income tax, many states impose a separate tax on at least some businesses, sometimes called a "franchise tax" or "privilege tax." This is frequently justified as a tax simply for the privilege of doing business in the state. As with state taxes on business income, the specifics of a state's franchise tax often depend in part on the legal form of the business. Franchise taxes are generally either a flat fee or an amount based on a business's net worth.

How Delaware State Business Income Tax Works

Delaware has a franchise tax and a corporation income tax, as well as a tax on limited liability companies, limited partnerships, and general partnerships. Your business might be subject to one or more of these taxes, depending on its legal form. Additionally, if income from your business passes through to you personally, that income will be subject to taxation on your personal state tax return.

Delaware's franchise tax, which is essentially a tax on the privilege of having a Delaware business, applies to traditional corporations (C corporations) and S corporations. Delaware provides two different methods for calculating the franchise tax: the "authorized shares method" and the "assumed par value capital method." You should use the method that results in the lowest tax. Delaware has a calculator you can download to calculate this tax.

Authorized Shares Method

Your corporation pays a flat fee that varies depending on the number of authorized shares, as follows:

  • 5,000 shares or less = $175 fee
  • 5,001 to 10,000 shares = $250 fee, and
  • 10,000 or more shares = $250 base fee + $85 for each additional 10,000 shares or fraction thereof. The maximum tax is $200,000.

Assumed Par Value Capital Method

The tax rate using this method is $400 per $1,000,000 (or part thereof) of the assumed par value capital of the corporation. The minimum tax is $400. To use this method, you must provide figures for all issued shares and total gross assets as reported on the corporation's federal tax return (IRS Form 1120, Schedule L).

Delaware corporation income tax is assessed at a flat 8.7% of taxable income derived from Delaware. (By comparison, the state's personal income tax rate varies from zero for nominal personal income to the highest rate of 6.6%.)

Delaware LLCs, limited partnerships, and general partnerships are required to pay an annual tax of $300.

Details for Five of the Most Common Forms of Delaware Business

Here's a brief look at additional details for five of the most common forms of Delaware business: corporations (C corporations), S corporations, LLCs, partnerships, and sole proprietorships.

Corporations

Delaware corporations are subject both to the state's franchise tax and its corporation income tax.

Example. For the 2022 tax year, your Delaware corporation had taxable net income of $100,000, has 10,000 authorized shares, assumed no-par capital of $100,000, and assumed par value capital of $100,000. Your corporation will owe Delaware corporate income tax in the amount of $8,700 (8.7% of $100,000). Also, assuming you choose to use the authorized shares method to calculate your franchise tax, your corporation will owe franchise tax in the amount of $250 ($250 tax for corporations with 5,000 to 10,000 authorized shares).

S Corporations

An S corporation is created by first forming a traditional corporation and then filing a special form with the IRS to elect "S" status. Unlike a traditional corporation, an S corporation generally is not subject to separate federal income tax. Rather, taxable income from an S corporation is passed through to the individual shareholders, and each shareholder is subject to federal tax on their share of that income. In other words, S corporations are pass-through entities. (Note that a shareholder's share of the S corporation's income need not actually be distributed to the shareholder in order for the shareholder to owe tax on that amount.) Delaware recognizes the federal S election and does not require Delaware S corporations to pay income tax. However, it does require these businesses to the state's franchise tax. In addition, an individual S corporation shareholder will owe tax to the state on their share of the company's income.

Example. For the 2022 tax year, your Delaware corporation had taxable net income of $100,000, has 10,000 authorized shares, assumed no-par capital of $100,000, and assumed par value capital of $100,000. Your corporation will owe Delaware corporate income tax in the amount of $8,700 (8.7% of $100,000). Also, assuming you choose to use the authorized shares method to calculate your franchise tax, your corporation will owe franchise tax in the amount of $250 ($250 tax for corporations with 5,000 to 10,000 authorized shares).

Limited Liability Companies (LLCs)

Like S corporations, standard Delaware LLCs are pass-through entities and are not required to pay federal or state income tax. LLCs are, however, required to pay a flat annual tax of $300 to the state. This annual tax aside, income from the business is distributed to individual LLC members, who then pay federal and state taxes on the amounts distributed to them.

Note that while, by default, LLCs are classified for tax purposes as partnerships (or, for single-member LLCs, disregarded entities), it is possible to elect to have your LLC classified as a corporation. In that case, the LLC would also be subject to Delaware's corporate income tax.

Example. For the latest tax year, your multi-member LLC, which has the default tax classification of partnership, had a net income of $100,000. The LLC will owe the state LLC tax of $300. Beyond this, the LLC's net income will be divvied up between you and your fellow LLC members, and you will each pay tax on your own portions on your respective state tax returns. The rate for each member will vary depending on their overall taxable income for the year.

Partnerships

General partnerships and limited partnerships are required to pay a flat annual tax of $300 to the state. However, this annual tax aside, income from partnerships is distributed to the individual partners, who then pay tax on the amount distributed to them on both their federal and state tax returns.

Example. For the latest tax year, your general partnership had a net income of $100,000. The LLC will owe the state general partnership tax of $250. Beyond this, the partnership's net income will be divvied up between you and your fellow partners, and you will each pay tax on your respective portions on your respective state tax returns; the rate for each partner will vary depending on their overall taxable income for the year.

Sole Proprietorships

Income from your business will be distributed to you as the sole proprietor, and you will pay tax to the state on that income.

Example. For the latest tax year, your general partnership had a net income of $100,000. The LLC will owe the state general partnership tax of $250. Beyond this, the partnership's net income will be divvied up between you and your fellow partners, and you will each pay tax on your respective portions on your respective state tax returns; the rate for each partner will vary depending on their overall taxable income for the year.

Note on Multistate Businesses and Nexus

The primary focus here is on businesses operating solely in Delaware. But if you're doing business in several states, you should be aware that your business might be considered to have nexus with those states and, therefore, might be obligated to pay taxes in those states. Also, if your business was formed or is located in another state but generates income in Delaware, it might be subject to Delaware taxes. The rules for taxation of multistate businesses, including what constitutes nexus with a state for the purpose of various taxes, are complicated. If you run such a business, consult with a tax professional.
