AN ACT TO AMEND TITLE 30 OF THE DELAWARE CODE RELATING TO PERSONAL INCOME TAX.

Like under House Bill No. 13 (HB 13) and House Substitute No. 1 for HB 13 (HS 1 for HB 13), this Act adjusts the existing personal income tax brackets and applicable tax rates. Under this Act, for taxable years beginning after December 31, 2025, taxable income between $60,000 and $150,000 will continue to be taxed at a rate of 6.6%, but taxable income above $150,000 will be taxed at higher rates. The result of the changes under this Act will be that those with a taxable income of $188,500 or less will see no increase in personal income taxes, with 94% of Delaware taxpayers receiving an overall tax decrease. Like HS 1 for HB 13, House Substitute No. 2 for HB 13 differs from HB 13 as follows: • Creates additional tax brackets for taxable income not in excess of $60,000. • Decreases the tax rate for all tax brackets for taxable income not in excess of $60,000. • Creates 3 additional tax brackets for taxable income above $60,000 instead of 2. • Names this Act the “The John Kowalko, Jr., Fairness in Taxation Act”. In addition, House Substitute No. 2 for HB 13 differs from HS 1 for HB 13 as follows: • Further decreases the tax rate for all tax brackets for taxable income not in excess of $60,000. • Revises the tax brackets so that tax rates increase for taxable income above $150,000 instead of $125,000. • Adjusts the personal income tax filing threshold to align with the revised tax brackets. • Makes technical corrections to conform existing law to the standards of the Delaware Legislative Drafting Manual.

AN ACT TO AMEND TITLE 6 OF THE DELAWARE CODE RELATING TO MULTILEVEL DISTRIBUTION COMPANIES.

This Act defines a multilevel distribution company and multilevel marketing program for purposes of this Subchapter. It sets forth mandatory disclosures that must be made by a multilevel distribution company to any potential purchaser that discloses details about the company, sometimes based on certain representations that the company makes. It sets forth that a multilevel distribution company may not require a participant in its marketing program to buy a good or service or pay any other consideration to participate in the marketing program unless it agrees to repurchase the goods, under certain conditions. It provides cancellation rights and guidelines. It permits a civil penalty to be imposed for violations of the required disclosures. It provides a private right of action for violation of the repurchase requirement, including treble damages, attorneys’ fees and costs to be awarded for a prevailing plaintiff. House Substitute No. 1 for House Bill 162 is different from the original in that it reduces some disclosure requirements, specifically the timing, the number of participants who have received the earnings in the amount or range specified within the last 3 years and the total number of participants who have entered into the contract with the seller within the last 3 years; introduces the standard of “clear and conspicuous” for disclosures while removing some specific requirements such as font size to allow for flexibility with a standard; and places the Act in a separate subchapter of Title 6.

AN ACT TO AMEND TITLE 14 OF THE DELAWARE CODE RELATING TO SCHOOL PROPERTY TAX EXEMPTIONS.

This Act gives a county, upon a county-wide reassessment of real property under § 8306(b) of Title 9, the authority to adopt an ordinance modifying the school property tax exemption amounts that were put in place on or before January 1, 1998. In doing so, this Act protects seniors and individuals with disabilities from significant school tax increases related to county-wide reassessments of property values.
