  2. These States got the benefits of using SALT Deductions as high-income filers live here and the taxpayer’s income increases the value of their SALT Deductions.
  3. But with the new updates, a limit has been made which will restrict the SALT deductions of these taxpayer’s up to the extent of $10,000


The changes in the SALT Deductions will adversely affect you if you are paying high property taxes due to the following reasons:

  2. If you have a large and heavy property tax bill due to owning of luxurious homes, or
  3. If you own a primary residence as well as one or more vacation homes due to which you have bigger property bills.

  5. The tax liability of the income class will reduce.
  6. The limits are same for single, as well as married filers, so the married couples will get less advantage with the new tax update on SALT deduction.

Q. Is there any substitute for SALT Deductions?

A. No. But you can avoid SALT deductions by choosing Standard Deductions in case it turns out to be more beneficial in particular tax year.

Q. Is it allowable to prepay 2019 SALT deductions in 2018?

A. Yes, it is possible to pay estimated taxes beforehand.

Q. Can you deduct both state income tax and sales tax?

A. Yes, you can deduct either state income tax or sales tax but not both.

According to the new updates on limitations for 2018-2025 U.S tax reforms have been imposed in comparison to prior deduction where there was no limit on SALT Deductions. Now in recent years, there are possibilities that Standard deduction will gain more importance than the SALT deductions due to its amount being doubled which will not make itemizing worthwhile for choosing.
