Are you referring to filing using the Standard Deduction or Itemized deduction? There's a sales tax deduction taxpayers are able to take if they itemize deductions.
Sales tax is deducted on Schedule A when you itemize your deductions. You have the option of deducting sales tax or State and Local Taxes (SALT). The most that you can deduct is $10,000 ($5,000 if you are filing as Married Filing Separately).
