Can I change from using the standard deduction to itemizing my deduction without beginning a new tax return?

CHANGE FROM STANDARD OR FORCE ITEMIZED DEDUCTIONS

Your itemized deductions have to be more than your standard deduction before you will see a change in your tax owed or tax refund.  The deductions you enter do not necessarily count “dollar for dollar;” many of them are subject to meeting  tough thresholds—medical expenses, for example, must meet a threshold that is pretty hard to reach. (Only the amount that is MORE than 7.5% of your AGI counts)   The software program uses all the IRS rules that apply to the expenses you enter, and it tells you if you have enough to use your itemized deductions or if using the standard deduction is more advantageous for you.  Under the tax laws that have been in effect since 2018, some deductions have been capped—there is a $10,000 limit to the itemized deductions for state, local, property and sales taxes.

The standard deduction makes some of your income “tax free.”  It is not a refund.  You will see your standard or itemized deduction amount on line 12 of your 2024 Form 1040.
