Limited liability companies can claim deductions but not tax-exempt status. S-Corps can claim deductions but not tax-exempt status. C-Corporations are not tax-exempt entities Not only are donations to Non-Profits tax-exempt, but NPOs can themselves apply for tax-exempt status. Sole Proprietorships are the least official business entity and cannot claim tax exemption.
Since limited liability companies can be a pass-through entity, owners are taxed on their personal income. S-Corp shareholders are taxed personally. The S-Corp, however, is not. C-Corp income is taxed at the corporate level first, then again at the personal level. This is called "double taxation." Non-Profits are only taxed once and can write off most of their expenses. Sole Proprietors are taxed only on their personal tax return.

Enter that estimated value in the most current year's cost line and add a note indicating that the entry is an estimate.
