Final answer:
Seth can claim a total of $11,100 as an itemized deduction for taxes paid during the current year, comprising $8,500 for state income tax, $1,000 for real estate taxes on investment land, and $1,600 for personal property taxes based on value.
Step-by-step explanation:
In addressing the amount Seth can claim as an itemized deduction for taxes paid during the current year, we consider the following: Federal income tax, state income tax, real estate taxes, state sales taxes, and personal property taxes based on value.
According to tax regulations, individual taxpayers can deduct state income taxes or sales taxes (whichever is higher), real estate taxes, and personal property taxes that are based on the value of the property. However, federal income taxes and self-employment taxes are not deductible.
Seth's deductible taxes would therefore be state income tax ($8,500), real estate taxes on the land held as an investment ($1,000), personal property taxes based upon value ($1,600), and the greater of either the state sales taxes or the amount by which the state income tax exceeds state sales taxes.
Since Seth's state income tax is significantly higher than his state sales taxes, he would deduct the entire state income tax amount. The total deduction Seth could claim for taxes paid in the current year would thus be the sum of the state income tax, real estate taxes, and personal property taxes, totaling $11,100.
