Introduction
Forming an LLC in Delaware doesn't give you one tidy tax bill. You can face four separate layers: Delaware's annual LLC tax, federal income-tax reporting, Delaware-source income rules, and taxes in whichever state (or country) you actually run the business from.
Founders tend to trip on the same three things:
- Treating the annual LLC tax as an income-tax return
- Expecting an annual report that Delaware doesn't require of LLCs
- Assuming Delaware formation switches off obligations elsewhere
For Australian founders and other non-US owners, there's an added layer of US federal reporting.
This guide covers what a Delaware LLC pays, how federal classification drives filing, the deadlines, a filing workflow, and the multi-state traps.
Key Takeaways
- Every Delaware LLC owes a $400 annual tax by June 1, whatever its income.
- Federal treatment depends on member count or an elected corporate classification.
- Delaware formation doesn't remove income-tax, payroll, or sales-tax duties in other states.
- Non-US owners may face extra IRS reporting, such as Form 5472.
- Confirm all figures with official Delaware and IRS sources before filing.
What Taxes Does a Delaware LLC Pay?
The annual LLC tax versus income tax
The Delaware Division of Corporations says Delaware LLCs must pay a $400 annual tax by June 1. It is a flat charge for existing LLCs, not a tax on profit. Late payment adds a $200 penalty plus interest of 1.5% per month. Check the current amount on the Division's page before paying.
Delaware and federal income tax
Delaware follows the LLC's federal classification. A pass-through LLC doesn't pay Delaware income tax itself; its members are liable on their shares. Delaware's 2025 partnership instructions require a return when the partnership has any Delaware-source income or loss. Nonresident members report that share on a Delaware nonresident return or a composite return.
Federally, members report allocated profit on their own returns or through an entity return, depending on classification. Self-employment tax is generally 15.3% (12.4% Social Security plus 2.9% Medicare). No single income-tax rate applies, because the result turns on income, deductions, filing status, and classification.
Sales tax, Gross Receipts Tax and payroll
Delaware has no general sales tax. It does impose Gross Receipts Tax on sellers, at rates from 0.0945% to 1.9914% depending on activity, with category-specific exclusions. Operating in Delaware can also trigger:
- A Delaware business license, with fees that vary by activity
- Employer withholding registration
- Unemployment insurance (UC-1 within 20 days of the first day of business)
Is there a minimum income threshold?
No universal one exists. The annual tax applies simply because the LLC exists. Income-tax filing depends on federal classification, income, source, residency, and state rules. The $400 figure on Schedule SE applies only to self-employment tax, not to general income-tax filing.
How Delaware LLC Tax Classification Affects Filing
Default treatment
- Single-member LLC: disregarded for federal purposes. The owner reports the business on their own return, such as Schedule C and Schedule SE for an individual.
- Multi-member LLC: taxed as a partnership. It files Form 1065 and issues a Schedule K-1 to each partner, who pays tax on their share whether or not cash was distributed.
A Form 1065 is an information return. The partnership itself does not pay federal income tax on the profits.
S corporation and C corporation elections
An LLC can elect corporate treatment using Form 8832. That election generally cannot take effect more than 75 days before filing or more than 12 months after. S status uses Form 2553, usually due within 2 months and 15 days of the tax year's start. A nonresident alien cannot be an S corporation shareholder.
Elections bring payroll or corporate reporting and extra bookkeeping. Savings aren't guaranteed, so get professional analysis first.
Delaware status doesn't change
A federal election changes federal (and Delaware income tax) classification. It doesn't replace the separate Delaware annual LLC tax.
A quick decision framework
Weigh these factors before choosing a classification:
- Number of members and their residency
- Expected profit and how much owners will draw
- Whether owners work in the business
- Payroll needs
- States of operation
- Your capacity for added administration
Delaware LLC Deadlines and Annual Compliance
Delaware obligations
The annual tax is due June 1. Pay through the Division's online portal; credit cards are accepted and ACH debit is required above $5,000. A Delaware LLC files no traditional annual report, which is a corporation rule. Don't apply corporation filing rules to an LLC.
The LLC must also keep a Delaware registered agent and office.
Federal calendar (calendar-year entities)
| Return | 2026 tax year due date |
|---|---|
| Form 1065, Form 1120-S | March 15, 2027 |
| Form 1120, Form 1040 / Schedule C | April 15, 2027 |
Form 7004 gives most entities a 6-month filing extension, and Form 4868 does the same for Form 1040. An extension to file is not an extension to pay.
Other filings that may apply
- Individual estimated tax, generally due April 15, June 15, September 15, and January 15, when you expect $1,000 or more owing
- Form 941 quarterly and Form 940 annually, where you have employees
- State returns, withholding returns, and Delaware GRT (monthly by the 20th, or quarterly)
Deadline checklist
Build a current-year calendar covering:
- Delaware annual tax (June 1)
- Federal entity or owner return
- Owner estimated payments
- State registrations and returns
- Payroll filings
- Registered-agent details
- Record retention
How to File and Manage Delaware LLC Tax Compliance
Step-by-step workflow
- Confirm the LLC's legal and federal tax classification.
- Obtain or verify the EIN. Owners without an SSN or ITIN can enter "foreign" on Form SS-4, line 7b, and apply through IRS international channels.
- Identify where the business and owners have filing connections.
- Gather books and records.
- Prepare federal and state forms.
- Pay balances and save confirmations.
Records to keep
Separate business and personal accounts from day one. Keep records covering:
- Income and expense detail
- Member ownership and distributions
- Payroll records and receipts
- Bank statements and prior returns
- Support for claimed deductions
The IRS generally says keep records 3 years, 6 years if you omit over 25% of gross income, and at least 4 years for employment-tax records.

Common Mistakes and Multi-State Considerations
Why Delaware formation doesn't settle other states
A Delaware LLC may need to register as a foreign LLC and pay tax where it has an office, employees, active owners, or inventory. No single factor always controls; each state applies its own nexus rules.
California, for example, charges an $800 annual LLC tax to LLCs doing business there, and applies a $500,000 sales threshold for out-of-state sellers.
Common errors
- Assuming no Delaware sales tax means none anywhere
- Confusing the annual tax payment with an annual report
- Overlooking Gross Receipts Tax
- Missing federal information returns
- Skipping estimated payments
Warning for non-US owners
A foreign owner of a partnership engaged in a US trade or business is treated as engaged in that business. Section 1446 withholding can run at 21% for corporate and generally 37% for noncorporate foreign partners.
A foreign-owned single-member LLC with reportable transactions files Form 5472 with a pro forma Form 1120, with a $25,000 penalty for failing to file.
Review residency, treaty issues, and state exposure with a qualified professional before assuming Delaware formation creates an exemption. Australian owners should also consider how Australian tax treats the LLC.
Frequently Asked Questions
What taxes does an LLC pay in Delaware?
The $400 annual LLC tax, plus federal income-tax reporting through the members or entity. Delaware-source or business-activity taxes (such as GRT) and taxes in other states may also apply.
Does a Delaware LLC need to file a tax return?
It depends on federal classification and activities. A partnership files an information return (Form 1065); a disregarded LLC's income goes on the owner's return.
Are Delaware LLCs required to file annual reports?
No. Delaware LLCs pay the annual tax instead. Annual reports are a corporation requirement.
How to file a Delaware annual report?
An LLC doesn't file one. Pay the annual tax through the Division of Corporations' official portal rather than a third-party site.
What is the deadline for Delaware LLCs to file their taxes?
The Delaware annual tax is due June 1. Federal, owner, payroll, and other-state deadlines differ, so verify current dates.
How are LLCs taxed in Delaware?
Generally as pass-throughs, unless the LLC elects S or C corporation status. Delaware-source income and owner residency affect filings, and formation in Delaware doesn't decide every obligation.
