The Department of Community Services and Development encourages Californians earning under $31,950 a year to file their taxes to claim the California Earned Income Tax Credit (CalEITC), a cash-back tax credit, and receive a larger tax refund.
The credit equals 30% of the sale price up to a maximum credit of $4,000. If you do not transfer the credit, it is nonrefundable when you file your taxes, so you can't get back more on the credit than you owe in taxes. You can't apply any excess credit to future tax years.

A common error is to deduct expenses for a portion of the home that is not used regularly and exclusively for business. Example: The basic local telephone service charge, including taxes, for the first telephone line into a home is a nondeductible personal expense.

The amount of the write-off for these utilities is determined by the percentage of the home that is used for business purposes. For example, if 20% of your home is used for business, you can write off 20% of your electricity and gas costs.
If you work from home, and are self-employed, an independent contractor, or a freelancer, you can write off the portion of your internet bill related to your work use. You can estimate this using a simple percentage.
