Standard Deductions and Itemized Deductions
Reducing Your Taxable Income
After you've determined your filing status, the next step is to reduce your taxable income. The tax system doesn't tax you on every single dollar you earn. Instead, it lets you subtract a certain amount from your income first. This subtraction is called a deduction.
A tax deduction lowers your taxable income, reducing how much of your earnings are subject to tax.
Think of it as a discount on your income. The lower your taxable income, the less tax you'll owe. There are two ways to claim deductions: you can take the standard deduction or you can itemize your deductions. You have to choose one path; you can't do both.
The Standard Deduction
The standard deduction is a specific dollar amount that you can subtract from your income. It's the simpler of the two options, and for that reason, it's what most people use.
The amount you can deduct depends on your filing status, age, and whether you are blind. The government sets these amounts, and they are usually adjusted each year for inflation. It's a straightforward way to reduce your taxable income without having to track every single deductible expense.
| Filing Status | Standard Deduction (2023) |
|---|---|
| Single | $13,850 |
| Married Filing Jointly | $27,700 |
| Qualifying Widow(er) | $27,700 |
| Married Filing Separately | $13,850 |
| Head of Household | $20,800 |
Note: Taxpayers who are age 65 or older or blind can claim an additional standard deduction.
Itemizing Your Deductions
If the standard deduction is the simple path, itemizing is the more involved one. Itemizing means you list out all your individual deductible expenses for the year. If the total of these expenses is more than your standard deduction amount, you might save money on your taxes by itemizing.
So, what kind of expenses can you itemize? The list is long, but some of the most common ones include:
- Mortgage Interest: If you own a home, you can often deduct the interest you paid on your mortgage.
- State and Local Taxes (SALT): This includes state income taxes, sales taxes, and property taxes. There is a cap on this deduction, currently limited to 💲10,000 per household per year.
- Charitable Contributions: Donations to qualified charities can be deducted.
- Medical and Dental Expenses: You can deduct medical expenses that exceed 7.5% of your adjusted gross income (AGI). This is a high threshold, so not everyone can claim it.
To itemize, you need to keep detailed records and receipts for all the expenses you plan to claim. You report these on a form called Schedule A, which you file with your tax return.
Which Should You Choose?
The decision is purely about the numbers. Which option saves you more money?
Generally, if a taxpayer's itemized deductions are larger than their standard deduction, it makes sense for them to itemize.
Let's look at an example. Suppose you are single, and your standard deduction is $13,850. You add up your potential itemized deductions for the year:
- Mortgage Interest: $7,000
- State and Local Taxes: $5,000
- Charitable Donations: $1,000
Your total itemized deductions would be $13,000.
In this case, your standard deduction ($13,850) is higher than your itemized deductions ($13,000). You would be better off taking the standard deduction to get a larger tax benefit.
For most people, especially after tax law changes in recent years increased the standard deduction amounts, the standard deduction is the better choice. However, if you own a home, live in a high-tax state, or make significant charitable donations, it's always worth adding up your itemized deductions to see if you can lower your tax bill further.
What is the primary purpose of a tax deduction?
You can take the standard deduction and also itemize your deductions in the same tax year.
Choosing the right deduction method is a key part of filing your taxes accurately and making sure you don't pay more than you need to.
