Delaware House Bill 400: overview of fee and tax changes
Delaware has long held its position as the corporate capital of the United States, with millions of businesses choosing the state for incorporation. The new legislative changes in House Bill 400 (HB 400), enacted May 21, 2026, significantly affect the cost of doing business in Delaware.
This blog breaks down what Delaware House Bill 400 includes, who it impacts, and what changes are made with organizations.
What is Delaware House Bill 400?
House Bill 400 is a comprehensive piece of legislation that amends multiple sections of the Delaware Code relating to fees and taxes administered by the Secretary of State. The bill includes broad increases to business-related fees like the ones below::
Formation and filing fees
Annual taxes for entities such as LLCs and partnerships
Fees for certified documents and filings
Charges for expedited processing services
The legislation raises annual taxes on certain entity types, such as LLCs, and increases various administrative fees tied to filings and document services. It also introduces significant increases to expedited service fees, with higher charges for same-day and priority processing.
The rationale behind the bill is to modernize fee structures that, in some cases, have not been updated for years and to align them with current operating costs. Most of these changes take effect on August 1, 2026, although certain annual tax increases for partnerships and LLCs are retroactively effective as of January 1, 2026.
Who will the bill affect?
HB 400 has wide-reaching implications across the business landscape, particularly for organizations that have chosen Delaware as their legal home. The entities that will be most impacted include:
Limited liability companies (LLCs)
Limited partnerships (LPs)
General partnerships (GPs)
Limited liability partnerships (LLPs)
Corporations incorporated in Delaware
Businesses requiring frequent filings or expedited services
Delaware is home to over 2 million business entities, including a large proportion of Fortune 500 companies, highlighting the scale of organizations that could be affected. Both large enterprises and small businesses may feel the impact, although the effect will vary depending on entity structure, filing volumes, and reliance on expedited services.
What does HB 400 mean for businesses?
For most organizations, HB 400 represents a material increase in compliance and operational costs associated with maintaining a Delaware entity.
Key implications include:
Higher annual costs
Annual taxes on LLCs and similar entities are set to increase, meaning businesses will need to budget for higher recurring expenses. Because certain tax increases apply retroactively to January 1, 2026, businesses may need to account for higher costs even before the August 1 implementation date.
Increased transaction costs
Routine actions such as filing certificates, obtaining copies, or making amendments may become more expensive due to higher administrative fees.
Greater cost for speed
Expedited services, often critical for time-sensitive transactions such as M&A activity or financing, could become significantly more expensive.
Strategic considerations for incorporation
Some organizations may begin reassessing their incorporation strategy, particularly where cost sensitivity is a factor or operations are limited to other jurisdictions.
However, it’s important to note that Delaware continues to offer advantages such as a well-established legal framework and the Court of Chancery, which remain key drivers for incorporation decisions.
Why this matters now
HB 400 represents one of the more notable shifts in Delaware’s fee structure in recent years. While the changes aim to support state funding and modernize outdated fees, they also introduce new considerations for businesses that depend on Delaware’s corporate ecosystem.
For legal teams, paralegals, and corporate governance professionals, this underscores the importance of maintaining visibility into entity-level costs and compliance obligations, particularly as regulatory environments continue to evolve.
