Also, understand the difference between an amortized asset and a capitalized asset.
An amortized asset is usually material and non-material costs incurred prior to opening the business. Expamples of this would be some forms of advertising your grand opening, or the cost of training your employees prior to opening. These costs are flat out deductible business expenses that can be deducted from business income. But they are amortized over the first 15 years of business with a portion deducted each  year, because it's not uncommon for a business to not have sufficient taxable income in that first year to deduct all of those start-up costs in one fell swoop. But the tax rules do give you the option to deduct a maximum of $5000 of startup costs in the first year, with any remaining startup costs amortized and deducted over the next 15 years.
A capitalize cost is not a full on deduction "per-se". It's a requirement to depreciate the cost of hard assets (like physical equipment used in the business to produce income) Most business assets, such as a building to house the business, or to house inventory are depreciated over 39 years. That means you can deduct the cost of that hard asset over 39 years of business. However, that deduction is not permanent. Whenever you close, sell or otherwise dispose of the business in the future, or if you sell or otherwise dispose of a business asset, all of that depreciation taken on those assets has to be recaptured in the year of disposition and taxes paid in the year of sale, closure or other disposition on all that prior depreciation taken in years past.
So in conclusion an amortized asset is one whose cost is permanently deducted from the income that asset produces. But a capitalized asset is one that is depreciated over time and the depreciated value is recaptured and taxed in the year that capitalized asset is no longer used in the business.
