Is the tax from building a detached garage deductible?

[Jake1311]

I recently built a large 40x60 detached garage/shop. My contractor’s bid included all applicable taxes. Can I deduct those taxes at my current state/county tax rate?

Yes, you can deduct the sales tax on construction of the garage if all of these conditions apply:

• You're itemizing. You have more total itemized deductions than the standard deduction.
• You're taking the sales tax deduction, as opposed to the state/local income tax deduction.
• The tax rate is equal to your state and local general sales tax rate.
• You (or your contractor acting as your agent) purchased the building materials and paid the tax.
