establishing a health reimbursement arrangement tax credit program and making an appropriation for improvements in the department of revenue administration's information management system.

Qualified taxpayer definition changed from 'an employer with more than one employee' to 'an employer with fewer than 50 employees,' dramatically narrowing who can claim the credit.

Per-employee credit changed from $400 in the first year and $200 in the second year to a flat $300 per covered employee per year for up to 2 consecutive years.

New requirement that the qualified taxpayer did not contribute to an employer-sponsored group health insurance plan for the covered employee in any of the previous 3 years.

New requirement that the contribution to a qualified account must be at least $300 more than the amount provided in the last benefit year of an employer-sponsored group health insurance program or qualified account prior to the first year the credit was claimed.

The annual aggregate cap on total tax credits awarded was reduced from $10,000,000 per taxable year to $2,500,000 per state fiscal year.

Credit application order changed: credit is now applied against RSA 77-E (business enterprise tax) first, with any unused portion then applied against RSA 77-A (business profits tax), rather than being claimed directly on the state tax return.

The application process changed from simply claiming the credit on a state tax return to submitting a formal application on a form prescribed by the commissioner, accompanied by required information or records.

Processing method changed from chronological order of filing to first come, first served basis, with random processing for applications received on the same day.

Carryover language simplified from a detailed 3-year carryover with reduction provisions to a straightforward 'not more than 3 succeeding taxable periods' carry forward.

The commissioner's rulemaking authority changed from 'propose rules' to 'adopt rules,' giving the department direct authority to finalize regulations rather than merely proposing them.

The bill title and scope expanded to include an appropriation for improvements in the department of revenue administration's information management system, though the specific appropriation text is not shown in this diff excerpt.
