A tax “write-off” is basically just slang for a tax deduction. A tax write-off or deduction is an expense you can claim on your tax return to reduce your taxable income. Different tax write-offs have specific rules that can impact your tax liability in various ways. Here’s how write-offs work, how much they are worth, and how to tell if you can claim them.
How do tax write-offs work?
A tax write-off is an expense that is subtracted from your taxable income. Another name for a write-off is a tax deduction. Businesses, self-employed individuals, and employees can claim tax write-offs if they meet specific eligibility requirements for the deduction.
Tax deductions fall into two categories:
- Above-the-line deductions and
- Below-the-line deductions
These are just references to where the deduction gets calculated on your tax return. Above-the-line deductions are also called adjustments to income and are calculated above your adjusted gross income. Below-the-line deductions are also called itemized deductions, and they are calculated below your adjusted gross income.
What can I write off on my taxes?
The type of expenses you can write off are determined by the tax laws. It’s important to understand if an item can be deducted before you try to write it off on your tax return. You can generally deduct expenses related to business operations, certain medical and dental costs, home mortgage interest, state and local taxes, charitable contributions, qualifying retirement contributions, and qualifying education expenses. However, personal expenses (like food, shelter, or entertainment) cannot be deducted.
Can I write off business expenses on my personal taxes?
If you’re self-employed, you can deduct business expenses directly from your income on your personal tax return, which reduces your overall taxable income. It’s important to keep detailed records and receipts for all expenses related to your business to ensure accurate reporting and to support your deductions in case of an audit. Common deductions include costs for office supplies, travel, and utilities used for business purposes.
Common tax write-offs
Being familiar with the most common tax write-offs can help you minimize your tax bill. Tax deductions are categorized into two main types: above-the-line deductions (or adjustments to income) and below-the-line deductions (or itemized deductions).
Above-the-line deductions are expenses that can be subtracted from gross income to determine your adjusted gross income (AGI). They can reduce your tax bill even if you don’t itemize deductions.
Below-the-line deductions refer to itemized deductions you can claim after AGI is calculated, allowing you to deduct certain expenses such as mortgage interest, state taxes, and medical expenses. Essentially, above-the-line deductions directly reduce taxable income, while below-the-line deductions reduce the tax bill after AGI is established.
The standard deduction is considered a below-the-line deduction, because you take it after you calculate your AGI. You can choose to claim this lump sum write-off instead of itemizing your deductions. Here are some important things to know about the standard deduction:
- Anyone can claim the standard deduction
- The standard deduction amount depends on your tax filing status
- You must choose between the standard deduction and itemizing your deductions – you can’t do both
Below you’ll find a list of common tax write-offs. We’ve broken them down based on where you claim them on your tax return.
Above-the-line tax deductions
When you’re filing a tax return, your above-the-line deductions are taken first. These amounts get subtracted from your gross income and are used to calculate your Adjusted Gross Income (AGI). AGI is then used to determine if you are eligible to take certain below-the-line deductions.
Some important above-the-line deductions include:
- Student loan interest – If you meet the requirements, you can write off a maximum of $2,500 paid in student loan interest.
- Educator expenses – If you’re a qualified educator, up to $300 can be deducted from your tax return for expenses you paid for out of pocket.
- Self-employment tax – Half of the amount you pay for self-employment tax is deductible on your tax return.
- Health insurance premiums – If you’re self-employed, you can deduct premiums you pay to provide health insurance for yourself and family members.
- Retirement plan contributions – This deduction is for contributions made to a traditional IRA.
Once you have taken your above-the-line deductions, you’ll decide whether to itemize or take the standard deduction.
Below-the-line (itemized) tax deductions
Once you have determined your AGI, you can choose to either take the standard deduction or itemize your deductions. Both help lower your taxable income dollar for dollar. This can result in a lower tax bill for you and even increase your refund if you don’t owe taxes.
Here are some important below-the-line deductions:
- State and Local Taxes (SALT) – The current tax law says you can deduct up to $40,000 ($10,000 if married filing separately) for state and local taxes.
- Home office – If you are self-employed, you can choose whether to deduct the square footage of your office space at a flat rate or a percentage of certain home office-related expenses.
- Business-related travel expenses – Certain travel expenses are also deductible if you’re spending at least one night away from home for business purposes.
- Donations to charity – 60% of your AGI is deductible for donations to public charities and certain public foundations. Certain private organizations limit deductions to 20%, 30%, or 50%.
- Mortgage interest – Single filers and couples filing jointly can deduct the interest on up to $750,000 of qualified residence loans. Couples filing separately can deduct interest on up to $375,000 of qualified debt.
- Unreimbursed medical expenses – Depending on where you live, you can deduct the cost of medical and dental expenses that exceed 7.5% of your AGI.

Tax write-off vs. tax deduction vs. tax credit
A tax write-off is a broad term that refers to any expense that can reduce taxable income, which often includes tax deductions. However, there is a difference between a tax credit and a tax deduction. A tax deduction lowers your taxable income, decreasing the amount of income subject to tax, while a tax credit directly reduces the amount of tax you owe.
How do I claim tax write-offs?
A tax write-off (deduction) can help reduce your taxable income, ultimately saving you money during tax season. Here’s a step-by-step on how to claim a tax write-off:
Step 1. Determine which expenses qualify as tax write-offs.
Step 2. Collect receipts, statements, and relevant tax forms that support your write-offs.
Step 3. Choose which below-the-line deduction to claim – either the standard deduction or itemized deductions.
Step 4. Fill out your tax forms. If you are itemizing, use Schedule A (Form 1040) to report your deductions. If not, you can indicate that you are using the standard deduction for your filing status.
Step 5. Review your forms to ensure all information is accurate before submitting your tax return.
