Research summary and collected compliance guidance for Delaware (for tax planners) Steps taken - Performed targeted web searches focused on Delaware compliance for tax planners, prioritizing official state sources (Delaware Division of Revenue, Delaware Division of Corporations) and reputable service providers (registered agent / corporate services and tax guidance sites). - Scraped and compressed key pages covering franchise tax, annual report requirements, filing portals, deadlines, penalty rules, calculation methods, and practical filing steps.

Key findings (high-level) - Who: All corporations incorporated in Delaware must file an Annual Report and pay Delaware franchise tax. Delaware LLCs, LPs, and other qualifying entities must pay an annual flat tax (LLCs/LPs typically $300) but generally do not file a corporation-style Annual Report. - Deadlines: Corporations’ Annual Report and franchise tax are due by March 1 each year.

LLCs, Limited Partnerships, and similar entities’ annual tax is due by June 1 each year. (State notices are mailed to the registered agent.) - Calculation methods (corporations): Two methods exist — Authorized Shares Method and Assumed Par Value Capital Method — and filers may select the method that gives the lower liability.

Minimums and maximums apply (see excerpts). Registered online portal is used for filing/payment. - LLCs/LPs/GPs: Flat annual tax (LLCs/LPs $300).

LLCs generally don’t file an Annual Report but must pay the tax to remain in good standing. - Penalties & interest: $200 penalty for not filing a completed Annual Report by the due date; interest at 1.5% per month on any unpaid tax balance.

Failure to pay for extended periods can lead to loss of good standing or voiding of the charter. - Estimated payments: Entities with tax liability of $5,000 or more must make estimated payments on a quarterly schedule (40% due June 1, 20% due Sept 1, 20% due Dec 1, remainder due March 1). - New/changed items to note: Recent reporting changes (subject to verification on official portal) include additional fields in the corporate Annual Report (examples: a “Nature of Business” selection for 2025 filings reported by corporate filing services).

Tax planners should verify any new required report fields each filing season. - Practical items for tax planners: maintain client calendars with March 1 and June 1 deadlines, collect and keep Delaware File Number and EIN, confirm registered agent and physical address requirements for corporate reports, decide corporation franchise tax calculation method before filing, use the Division of Corporations online portal to file and pay, and prepare for penalties/interest if late.

Why the research is complete - We located and extracted guidance from the Delaware Division of Revenue (official franchise tax and deadline guidance) and multiple professional sources that corroborate deadlines, methods, amounts, and practical filing steps.

These provide the core compliance facts a tax planner needs to prepare clients and create checklists and calendar reminders. Next recommended actions for the user (tax planners) 1.

Confirm client entity type and Delaware File Number; add March 1 (corporations) and June 1 (LLCs/LPs) recurring reminders.

For corporations

assemble authorized shares data, issued shares and total gross assets (if preferring Assumed Par Value method) to compute both methods and choose the lower tax.

For LLCs/LPs

verify flat tax payment and pay via the Division of Corporations / Revenue portal.

Ensure registered agent is current and has received any mailed franchise tax notices.

Collect required report data (officers/directors for corporations; physical address not being registered agent address) and any new report fields (e.g., Nature of Business).

If tax liability is expected >= $5,000, compute estimated payments and apply the quarterly schedule.

Keep documentation of filings and payments for client records and for obtaining Certificates of Good Standing when needed. Citations and verbatim excerpts supporting the findings
