How do you calculate the Federal tax credit?

We assume the federal tax credit is 30% of the Qualified Property Costs. There is no limit for business installations. Pool and Spa installations do not qualify however a 10% investment tax credit may apply for commercial pool/spa systems

We use the gross system cost as the "Qualified Property Cost" - (i.e.) other incentives that may apply are not deducted from the cost basis for calculating the tax credit. Please consult with a Tax Professional to make the appropriate determination for your tax return.

We attempt to provide direct links to incentive program information -- try "clicking" the line title.
