Formation date vs. effective date

Delaware allows businesses to specify a future effective date when filing, creating two different dates:

• Effective date: When your entity officially began operations (if you specified a later date)

For most Delaware entities, these dates are identical, but always verify which date you need for specific compliance requirements.
