Quick Summary
- Box 14 is employer-defined — there is no single universal IRS meaning for every Box 14 entry
- Common labels include CA SDI, NY PFL, union dues, and local disability or payroll taxes
- Many Box 14 entries are informational only, but some matter when you file a state return or verify payroll records
- If you worked in states like California or New York, Box 14 often shows state-specific items that do not appear the same way on every W-2
Box 14 is one of the most confusing parts of a W-2 because it is not standardized the way Box 1, Box 2, or Box 12 are. Two people can work similar jobs, earn similar pay, and still see completely different text in Box 14.
That does not automatically mean something is wrong. In most cases, Box 14 is just a place where payroll adds extra information that might be useful to you, your state tax return, or your records. The hard part is that employers often use abbreviations that look like secret code.
If you are comparing a W-2 from California with one from New York, the difference can be even more obvious. State payroll rules are not identical, so Box 14 often becomes the catch-all space for items that matter locally.
Why Box 14 exists on a W-2
Think of Box 14 as the overflow drawer on the W-2. The IRS gives employers a fixed set of boxes for wages, withholding, Social Security, Medicare, and a few coded benefits. But real payroll is messier than that template.
So employers use Box 14 to report items like state disability insurance, paid family leave contributions, union dues, education assistance notes, employer-paid taxes, or other state and local payroll details. Some of these items are purely informational. Some may help you or your tax software categorize state-related amounts.
📊 Key Number
There is no single official federal master list for every Box 14 label. That is why the same type of deduction may appear as CA SDI, CASDI, or another payroll abbreviation.
| W-2 box | How standardized it is | Example |
|---|---|---|
| Box 1 | Highly standardized | Federal taxable wages |
| Box 12 | Standardized with IRS codes | Code D for 401(k) |
| Box 14 | Employer-defined | CA SDI, NY PFL, union dues, local disability |
Common Box 14 labels and what they usually mean
The label matters more than the box itself. You are usually trying to answer two questions: what payroll item is this, and does it change my tax filing?
Here are common examples that workers see all the time.
| Box 14 label | What it usually means | Example amount | What to do with it |
|---|---|---|---|
| CA SDI / CASDI | California State Disability Insurance withholding | $698 | Compare it with your final pay stub and your California withholding records |
| NY PFL | New York Paid Family Leave contribution | $212.25 | Usually informational, but keep it with your New York records |
| UNION | Union dues withheld through payroll | $742 | Usually recordkeeping only for most filers |
| DI | Disability insurance or a state disability item | $184 | Ask payroll which program it refers to |
| LTT / Local Tax | Local payroll tax label used by an employer or locality | $318 | Check whether it already ties to local wage boxes elsewhere on the W-2 |
The same label can still mean slightly different things across payroll systems. That is why the best source is your employer’s payroll department, not a random internet thread. For example, “DI” might mean a state disability contribution, a private plan, or a payroll shorthand that only makes sense inside one company.
💡 Action Tip
If Box 14 uses an abbreviation you do not recognize, ask payroll this exact question: “Can you tell me what this Box 14 label means in plain English, and whether it affects my federal or state tax return?”

What actually matters for your tax return
Most Box 14 panic is unnecessary. Many entries do not create a new deduction or credit on your federal return. They are often there to help document how payroll handled a state or local item.
What matters is whether the amount connects to another tax rule. A California disability item may matter for state recordkeeping. A local tax label may matter if you are reconciling city withholding. Union dues usually do not create the tax break people expect on a standard individual federal return.
⚠️ Heads Up
Do not force a Box 14 amount into tax software just because there is an empty field. If the software asks for a description, enter it only if you know what the item is. Guessing can create a wrong state return faster than leaving an informational item alone.
Box 14 is also useful as a payroll error check. If your W-2 says CA SDI $698 but your last pay stub shows year-to-date CA SDI of $524, that mismatch is worth questioning before you file.
How to check if Box 14 looks wrong
Start with your final pay stub for the year. Compare the year-to-date number on the pay stub to the Box 14 amount. If the label is clear and the numbers match, you probably do not have a problem.
Then look at the state. If the label is tied to a state-specific program, make sure it fits where you actually worked. A New York paid leave label on a worker who never had New York wages is the kind of mismatch that deserves a payroll question.
📊 Key Number
A fast review takes about 3 checks: match the amount to your final pay stub, confirm the state matches your work location, and ask whether the item is informational only or filing-relevant.
| Check | What you compare | Good sign |
|---|---|---|
| 1. Amount check | Box 14 vs year-to-date pay stub total | Numbers match or are clearly explained |
| 2. State check | Label vs actual state where you worked | CA item for California work, NY item for New York work |
| 3. Tax impact check | Payroll explanation vs tax software field | You know whether to enter it, ignore it, or ask more questions |
How to put this to work
1. Read the label exactly as written. Do not paraphrase it before you search or ask payroll. “CA SDI” and “SDI” are not always interchangeable.
2. Match the amount to your final pay stub. If the year-to-date figures disagree, stop and ask for clarification before filing.
3. Decide whether the item is informational, state-related, or an actual filing input. If you are unsure, get a written payroll explanation and keep it with your W-2 records.
If you want a broader paycheck cross-check, compare your take-home in California and New York. State payroll programs often explain why Box 14 looks busier on some W-2s than others.
