How do you depreciate business sign?

To depreciate a business sign, you first need to determine its useful life and salvage value. The most common methods for depreciation are straight-line depreciation, where the cost is evenly spread over the sign's useful life, or accelerated methods like double declining balance. For example, if a sign costs $10,000 with a useful life of 10 years and no salvage value, you would deduct $1,000 annually using straight-line depreciation. Ensure to adhere to relevant accounting standards and tax regulations when calculating depreciation.
