The maximum deduction amount you can take depends on the type of deduction, as well as any applicable limits.
For example, you can deduct 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. 16, 2017), contributions to a traditional individual retirement account (IRA), 401(k) plan, or another qualified retirement plan, up to $10,000 of state and local taxes, and contributions to a health savings account, up to annual limits, among others.
Additionally, you can deduct up to $10,000 of your total payments each year for property taxes, state income tax, or state and local sales tax. Lastly, you can claim the Standard Deduction, which varies depending on your filing status, age, and other factors.
