To determine if you itemized your deductions in the previous tax year, you can check your tax documents from that year. If you itemized, you would have filed Schedule A (Form 1040), which lists all your itemized deductions such as medical expenses, state and local taxes, mortgage interest, and charitable contributions.
If you filed your taxes with Online Taxes in the prior year, you can log into your account and select the previous tax year from the top of the page. Then, choose “View Forms” to access your previously filed tax return and check whether Schedule A was included.
If you did not file with Online Taxes and do not have copies of your accepted return, you may need to request a copy of your tax return from the IRS. You can do this through the IRS website or by contacting the IRS directly.
Itemizing deductions is an option available to taxpayers who have total itemized deductions that exceed the standard deduction for their filing status. If you took the standard deduction, you did not itemize.
