This deduction adds to existing standard deductions, provides up to $12,000 for couples, and requires a Social Security number and filing status other than Married Filing Separately.
Electricity and Gas Write-offs
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.
