Why is Solar credit in MA being split up 15% for this year and 15% to be carried over to next year instead of full 30% in full?

[CherylW · Accepted solution]

This, from Mass.gov:

For the credit, you're allowed the smaller of:

• 15% of the net expenditure for a renewable energy source property, or
• $1,000.

Unless you have a credit that is larger than the tax you owe, you won't have a carryover to next year.
