For some taxpayers, itemizing on a tax return can make a huge difference in their tax bill. But itemized deductions aren't necessarily no-brainers.
Here are some things you need to know about what itemized deductions are, and what it means to itemize on your tax return.

Itemized deductions, definition
Itemized deductions are certain expenses allowed by the IRS that can decrease your taxable income (aka the amount of your income that's subject to taxes).
When you itemize on your tax return, you opt to pick and choose from the multitude of individual tax deductions out there instead of taking the flat-dollar standard deduction.

Types of itemized deductions
There are many types of itemized deductions out there, but claiming them can be complicated. Each type of deduction usually has its own set of rules about who and what qualifies, so make sure to learn more about each benefit to understand if it makes sense for your situation.
Here are a few of the most common itemized deductions:
Medical expense deduction
The IRS lets taxpayers deduct a certain percentage of unreimbursed medical and dental expenses they've amassed throughout the year. The keyword here is unreimbursed: to qualify, expenses must have been paid for out of pocket, meaning your insurance could not have covered them or reimbursed you for them. These types of expenses can include prescription drugs, payments to doctors, hospital care, dentures, and more.

Property tax deduction
Homeowners who are subject to high property taxes can take advantage of what's known as the SALT deduction, which allows them to write off up to $10,000 in property taxes and either local state and local income taxes or sales taxes.

Mortgage interest deduction
Taxpayers who have a home mortgage can take advantage of this itemized deduction that allows them to reduce taxable income each year they pay interest toward the loan. The deduction is capped at the first $750,000 of mortgage debt for either your main or second home. For those who are married but file separately, the limit of deductible mortgage interest is capped at the first $375,000. Plus there are different rules for mortgages before December 2017.

Charitable contribution deduction
Contributions made to IRS-recognized charities are considered deductible expenses. How much you are able to deduct depends on the type of contribution made, but typically it ranges from 20% to 60% of your adjusted gross income (AGI).
Advantages of itemized deductions
Itemized deductions might add up to more than the standard deduction. The more you can deduct, the less you’ll pay in taxes, which is why some people itemize — the total of their itemized deductions is more than the standard deduction.
Some situations make itemizing especially attractive. If you own your home, for example, your itemized deductions for mortgage interest and property taxes may easily exceed the standard deduction, saving you money.
Disadvantages of itemized deductions
You have to understand the rules. As mentioned earlier, some itemized deductions come with a few hurdles. If you have medical expenses, for example, you can only deduct the portion that exceeds 7.5% of your adjusted gross income.
You might have to spend more time on your tax return. If you itemize, you’ll need to set aside extra time when preparing your returns to fill out Form 1040 and Schedule A, as well as the supporting schedules that feed into those forms.
You need proof. You need to be able to substantiate your deductions. That means keeping records and being organized. If you normally take the standard deduction and are thinking of itemizing when preparing your return next year, start saving your receipts and other proof for your deductions now.

Advantages of the standard deduction
The standard deduction is basically a flat-dollar, no-questions-asked reduction in your adjusted gross income. When you take the standard deduction, you basically opt to take a flat-dollar deduction instead of picking and choosing from the multitudes of individual tax deductions out there.
Here are some big reasons people take the standard deduction instead of itemizing on their tax returns.
It's faster. Taking the standard deduction makes the tax-prep process relatively quick and easy, which probably is one reason most taxpayers take the standard deduction instead of itemizing.
It usually gets bigger every year. Congress sets the amount of the standard deduction, and it’s typically adjusted every year for inflation.
Some people get more (or less). The standard deduction is higher for people 65 or older and/or blind, though filing status is still a factor. And if someone can claim you as a dependent, you get a smaller standard deduction.
One note for married people: You can’t take the standard deduction if you’re married but filing separately and your spouse chooses to itemize. You both have to do the same thing — either itemize or take the standard deduction.

Standard deduction vs. itemized deductions
Which one should I take?
If your standard deduction is less than your itemized deductions, you probably should itemize and save money. If your standard deduction is more than your itemized deductions, it might be worth it to take the standard and save some time.
If you’re using tax software, it’s probably worth the time to answer all the questions about itemized deductions that might apply to you. Why? The software or your tax preparer can run your return both ways to see which method produces a lower tax bill. Even if you end up taking the standard deduction, at least you’ll know you’re coming out ahead.
