Yes, you can deduct the sales tax paid for the materials used to build your home. However, be aware that the deduction will be limited to $10,000 (or $5000 if married filing separate). This limitation is applied to state and local taxes claimed on Schedule A as part of the Tax Cuts and Jobs Act.
Be sure to keep the receipts and proof that you paid the builder the cost of the materials.
