The Tax Cuts and Jobs Act of 2017 nearly doubled the standard deduction amount for tax years 2018 through 2025.
In addition, the SALT deduction (state, local, property, and sales tax) is now capped at $10,000 ($5,000 for couples filing separately), whereas in prior tax years there was no cap.
As a result of these and other tax law changes, our estimate is that nearly 90% of tax filers will now be taking the higher standard deduction, up from around 70% last year. And if you're in the 90% group, you won't see a change in your refund after entering your mortgage interest and property taxes.
