Here’s What You Need To Know About Solar Tax

In 2015, the congress have renewed the popular solar tax credit which allowed more homeowners to benefit from solar power. When you install a solar power system, the federal government rewards you with a tax credit for investing in solar energy. Thus, money will be deducted from the amount of federal tax you owe each year just by having solar power. Since Tramp has been increasingly interested in raising the tax, you have nothing to worry about as for 2018 and 2019, the tax credit is still in place.

  • Credit steps down –It’s important to understand that the value of the credit will go down as the years pass. In 2018 and 2019, the credit will remain 30%. In 2020, the tax will be of 26% and in 2021, it will be of 22%. Whereas, in 2022, you will receive no credit if you don’t use it in commercial projects.
  • Easy to claim –There are numerous expenses that you can claim on. Some of them are solar equipment, freight shipping costs, solar consulting fees, professional installer fees, electrician fees, engineer fees, and tools bought or rented. It’s important to understand that the cost will vary depending on the approach you take to installation.
  • There’s no middle man – Unlike electricity, you will be in charge of the system as you own everything. Therefore, you will have full control of how much the appliances can be powered with and when to turn it on or off. You don’t have to worry whether it will function at nighttime or in cloudy weather as the solar panels are innovatively designed to ensure maximum efficiency.
  • Money-saving – The bill states that if the motor doesn’t have a large capacity, you won’t have to pay tax. This includes all of the models that we’ve mentioned. In other words, if your house runs on solar power, you will save a lot of money as you won’t have to pay the same taxes someone with unsustainable electricity does.
