The brand new 2025 Trump tax regulation — One Large Lovely Invoice Act — created a number of new tax deductions. Some individuals say they’re above-the-line deductions, however that’s not true. These new deductions are all below-the-line. This publish explains the distinction between the several types of tax deductions.
Not a Tax Credit score
To start with, a tax deduction just isn’t a tax credit score.
A tax credit score straight reduces your tax dollar-for-dollar. If you happen to’re presupposed to pay $5,000 in tax, a $1,000 tax credit score reduces your tax to $4,000.
A tax deduction lowers your taxable revenue, which not directly reduces your tax. If you happen to’re presupposed to pay $5,000 in tax, a $1,000 tax deduction lowers your taxable revenue by $1,000, which then reduces your tax by a fraction of it, relying in your marginal tax charge.
Due to this fact, a $1,000 tax deduction is price loads lower than a $1,000 tax credit score.
Inside tax deductions, there are above-the-line deductions, customary deduction, itemized deductionsand a set of deductions which can be neither above-the-line nor itemized.
Above-the-Line Deductions
Above-the-line deductions are formally known as changes to revenue. The “line” refers back to the line on the tax kind on your Adjusted Gross Revenue (AGI). Your AGI is a key quantity that determines your eligibility for a lot of tax breaks. It’s the start line for Modified Adjusted Gross Revenue (MAGI) for numerous functions, for example, little one tax credit score, ACA medical insurance premiumsand Irma.

A tax deduction is both above-the-line or below-the-line. Above-the-line deductions decrease your AGI and assist you qualify for different tax breaks. Under-the-line deductions don’t have an effect on your AGI, and so they don’t assist you qualify for different tax breaks.
Due to this fact, a $1,000 above-the-line tax deduction is best than a $1,000 below-the-line deduction.
Solely particular tax deductions are designated as above-the-line. They’re listed on web page 2 of Kind 1040 Schedule 1. Listed here are some examples:
- HSA contributions made outdoors of payroll
- Deductible Conventional IRA contributions
- Educator bills
- 1/2 of the self-employment tax
- Contributions to small enterprise retirement plans
- Self-employment medical insurance deduction
Normal Deduction Or Itemized Deductions
The usual deduction and itemized deductions come after the AGI. They’re below-the-line.
The usual deduction and itemized deductions are mutually unique. If you happen to select to take the usual deduction, you surrender itemizing your deductions. If you happen to select to itemize, you forego the usual deduction.
Sometimes, you itemize solely when the sum of your itemized deductions is bigger than your customary deduction. You retain it easy and take the bigger customary deduction when you understand you don’t have that a lot in itemized deductions.
Taking the usual deduction is a win since you’re deducting greater than your allowable itemized deductions. Over 80% of taxpayers take the usual deduction. So do I.
Itemized deductions are listed on Kind 1040 Schedule A. Mortgage curiosity, state revenue tax, property tax, and donations to charities are typical itemized deductions (apart from the brand new $1,000/$2,000 charity donations deduction whenever you don’t itemize).
Flooring and Caps
Simply because one thing is tax-deductible, it doesn’t imply you possibly can deduct 100% of it. It is because some deductions should first clear a ground.
For instance, medical bills are tax-deductible, however you possibly can solely deduct the portion that exceeds 7.5% of your AGI. That involves zero for many individuals.
Some deductions have a cap. You’ll be able to deduct solely as much as the cap, even in case you paid extra. State and native taxes (SALT) are a widely known instance of this.
The brand new 2025 Trump tax regulation elevated the SALT cap. Extra persons are anticipated to itemize deductions, however they’re nonetheless a minority. Over 80% of individuals will nonetheless take the usual deduction.
Under-the-Line, Accessible-to-All
Within the outdated days, particular person tax deductions have been both above-the-line or itemized deductions. Solely above-the-line deductions have been obtainable to everybody. Under-the-line deductions have been solely the usual deduction or itemized deductions. After taking the above-the-line deductions, you could possibly solely take the usual deduction in case you don’t itemize.
This dichotomy between above-the-line and must-itemize not holds. Congress has created a number of deductions in recent times which can be below-the-line however don’t require itemizing. You’ll be able to nonetheless take these deductions whenever you take the usual deduction, however they don’t have an effect on your AGI. A deduction obtainable to everybody doesn’t essentially imply it’s above-the-line.
Itemize | Don’t Itemize | |
---|---|---|
Above-the-Line Deductions | ✅ | ✅ |
Normal Deduction | 🚫 | ✅ |
Itemized Deductions | ✅ | 🚫 |
Under-the-Line, Accessible-to-All | ✅ (until particularly excluded) | ✅ |
Each above-the-line deductions and this new set of deductions can be found to everybody (until it’s particularly excluded). The distinction is in whether or not it impacts your AGI. Solely the usual deduction and itemized deductions are nonetheless either-or.
Congress created these below-the-line, available-to-all deductions as a result of they wished to make them obtainable to extra individuals. Giving them to solely those that itemize deductions (10-20% of taxpayers) can be too limiting. However Congress didn’t need these deductions to decrease the AGI and set off different tax breaks. A few of these deductions themselves have limits primarily based on the AGI. Making them above-the-line would create a round math drawback.
Listed here are among the below-the-line available-to-all deductions:
All of those deductions are nonetheless obtainable in case you take the usual deduction, however they don’t decrease your AGI.
