There is a limit of $10,000 for a taxpayer's annual deduction for local and state taxes, which includes property taxes, local sales tax, and state income taxes.
This applies to both single and married filing jointly taxpayers; the amount is limited to $5,000 for married taxpayers filing separately. Taxpayers typically have the option of writing off either their state income taxes or their local sales taxes.
The IRS has a calculator that can help determine the amount of sales taxes that can be deducted. Additionally, some states may have additional allowable deductions or different restrictions on deductions, so it's important to read the state's tax forms closely to see if there are any deductions for which you might qualify.
Other common deductions that can be claimed on a federal income tax return include up to $2,500 of student loan interest, mortgage interest on up to $750,000 of secured home mortgage debt ($1 million if you bought the home before Dec. 2017), and charitable contributions.
