This legislative bill pertains to individual income taxation in Minnesota, introducing a "budget surplus credit." It defines who qualifies for this credit and outlines how it will be calculated and distributed.

Key aspects of the bill include:

1. Qualifying Taxpayers: These are individuals or married couples who have filed their Minnesota income tax returns on time for a specific tax year (an even-numbered year before a budget report is issued). Dependents, as defined under certain sections of the Internal Revenue Code, do not qualify.

2. Credit Calculation: The credit a taxpayer receives is calculated based on their tax liability for a particular qualifying year and a percentage that is determined by the amount of the state’s budget surplus.

3. Payment of Credit: The state revenue commissioner is tasked with determining the credit amount for each qualifying taxpayer and issuing refunds as needed. This process is conducted without requiring taxpayers to file a specific claim for this credit.

4. Special Provisions for Part-Year Residents: If a taxpayer didn't reside in Minnesota for the entire year, their credit is adjusted proportionately based on the time they lived in the state.

5. Administrative Details: The bill grants the revenue commissioner the authority to undertake necessary actions to process and distribute these refunds, possibly using private contractors to issue the payments.

6. Funding: Appropriations for these refunds will be made from the general fund by the end of each odd-numbered year to cover the costs incurred.

Essentially, this bill aims to return a portion of the state’s budget surplus back to taxpayers, providing financial relief based on their previous tax liabilities and the state's fiscal health at the end of a biennium.
