Local withholding tax is an income tax that a city, county, township, or school district takes out of your paycheck, collected by your employer and sent to the local tax authority much the way federal and state income taxes are. Roughly 16 states allow some form of local income tax, so whether it affects you depends entirely on where you live and where you work. Rates, filing rules, and even the name of the tax vary from one place to the next.
Where It Applies and How Much
Only a minority of states grant cities, counties, or school districts the power to tax earned income. In some of those states nearly every municipality levies the tax; in others only a handful of large cities do. You may see it called earned income tax, municipal income tax, or simply local income tax, but the mechanics are the same: a percentage of your wages comes out of each paycheck and gets remitted to a local collector.
Most localities use a flat rate, often somewhere between 0.5% and 3%. A few large cities use graduated brackets that rise with income. The money funds local schools, police, fire departments, and infrastructure, so the rates reflect each community’s budget rather than any national standard.
Where You Live Versus Where You Work
The biggest source of confusion is figuring out which jurisdiction gets to tax you. Local governments claim taxing authority based on two connections: where you live and where you physically perform work. Some localities impose only a resident tax, some tax anyone earning income inside their borders, and some do both.
If you live and work in the same city, it’s simple: one jurisdiction, one rate. Cross a municipal line to get to the office and it gets more complicated. Your employer typically withholds for the workplace jurisdiction first, because the business is registered there and knows that rate. Your home municipality may still expect a share.
What you actually owe depends on the relationship between the two. If the workplace rate equals or exceeds your resident rate, you generally owe nothing extra at home. If your resident rate is higher, you owe the difference. The resident jurisdiction usually gives a credit for whatever you already paid where you work, so you aren’t taxed twice on the same dollar. In practice, you pay the higher of the two rates, not the sum.
What Employers Have to Do
Registering and Finding the Right Rate
An employer operating in a jurisdiction with a local income tax has to register with the local tax collector and open a withholding account. That triggers the obligation to deduct and remit tax for every employee working at that location. To set the correct rate for each worker, employers rely on a residency certification form the employee fills out at hire and updates whenever they move. The form identifies the home municipality and its tax rate, usually tied to a location code.
Getting the rate right is harder than it sounds when employees live across dozens of municipalities with different percentages. Many jurisdictions publish rate tables pairing every municipality in the region with its current rate and code, and employers are expected to use those tables and update withholding when rates change.
Withholding, Remittance, and the W-2
Once the rate is set, the employer deducts the tax from each paycheck and holds those funds in trust for the taxing authority. Remittance schedules vary, but quarterly filings with a year-end reconciliation are common. At year-end, employers report local wages, local tax withheld, and the locality name in Boxes 18, 19, and 20 of each employee’s Form W-2.1Internal Revenue Service. Form W-2 Wage and Tax Statement If an employee worked in more than one locality during the year, each one gets its own entry.
An employer that fails to withhold the required local tax can be held directly liable for the missing amount, and in many jurisdictions the responsible individuals inside the company can be held personally liable too. Payroll errors here carry consequences beyond a corrective filing.
What You Have to Do as a Taxpayer
Filing an Annual Return
Even if your employer withholds local tax from every paycheck, you still generally need to file a local return. The return reconciles what was withheld against what you actually owe, accounting for income changes, moves, or withholding errors. The deadline typically mirrors the federal April 15 date, though some localities set their own.
The amount in Box 19 of your W-2 is applied as a credit on your local return. If more was withheld than you owe, you claim a refund. If less, you pay the balance. If you moved during the year, you usually file a part-year return in each municipality, splitting income by the dates you lived in each place.
Estimated Payments for Income That Isn’t Withheld
If you earn income that isn’t subject to local withholding, such as freelance earnings, rental income, or investment gains your locality taxes, you’re responsible for making quarterly estimated payments directly to the local tax authority. The schedule follows the same general pattern as federal estimated taxes: mid-April, mid-June, mid-September, and mid-January of the following year.2Internal Revenue Service. Estimated Tax Miss them and you can face underpayment penalties and interest on top of the tax itself.
If You’re Self-Employed
Self-employed workers owe local income tax on their net self-employment earnings and have to calculate the amount, make quarterly estimated payments, and file an annual local return. The IRS expects self-employed individuals to use estimated payments to cover federal, state, and local obligations throughout the year rather than settle up in one lump sum.3Internal Revenue Service.

Reciprocity Agreements and Credits
Where you live in one taxing jurisdiction and work in another, reciprocity agreements can settle things cleanly. Under a reciprocity agreement, the two jurisdictions agree that only the resident municipality taxes the employee’s wages. You file an exemption form with your employer, the workplace jurisdiction stops withholding, and your employer withholds only for your home municipality.
Not every pair of jurisdictions has such an agreement. Where none exists, the fallback is a credit. You pay the workplace tax through employer withholding, then claim a credit on your resident municipality’s return for the amount already paid. Your resident jurisdiction reduces its tax bill by the credit, so the net effect is that you pay the higher of the two rates rather than both stacked together. Forget to claim the credit and you’ll overpay, and recovering the money means filing amended returns with both jurisdictions.
Remote and Hybrid Work
Remote work has scrambled assumptions local tax systems were built on. Traditionally, your workplace tax was straightforward: you commuted to an office, and that office’s city collected the tax. Now an employee might work from home three days a week in one municipality and commute to an office in another for two. Some localities want the tax allocated based on where work is physically performed each day. Others tax the income based on where the employer’s office sits, regardless of whether the employee ever shows up.
A handful of states apply what’s called the convenience-of-the-employer rule. If you work remotely for your own convenience rather than because your employer requires it, your wages can still be taxed by the state or city where the employer’s office is located. You may owe taxes to both your home jurisdiction and the employer’s jurisdiction, with limited credit relief. Several states adopted temporary pandemic-era rules sourcing all wages to the employer’s location even when employees worked entirely from home, and some of those disputes are still being litigated.4National Conference of State Legislatures. State and Local Tax Considerations of Remote Work Arrangements
If you split time between municipalities, keep a log of where you physically work each day. Some jurisdictions require day-by-day allocation, and without records you’ll have a hard time claiming a refund for days worked outside the taxing jurisdiction.
Deducting Local Taxes on Your Federal Return
Local income taxes you pay are deductible on your federal return if you itemize. Under 26 U.S.C. ยง 164, state and local income taxes, property taxes, and either sales taxes or income taxes (your choice, not both) count toward the deduction. For 2026, the total deduction for all state and local taxes combined is capped at $40,400, or $20,200 for married individuals filing separately.5Office of the Law Revision Counsel. 26 USC 164 – Taxes That cap covers state income tax, local income tax, and property tax together.
Take the standard deduction and you get no separate benefit from local taxes paid. For taxpayers in high-tax localities who also own property, the cap can mean a portion of your local income tax effectively generates no federal tax benefit. It still matters when you’re deciding whether itemizing beats the standard deduction.
Penalties for Getting It Wrong
Employers who fail to withhold, remit, or report local taxes face consequences that escalate with the violation. A late remittance typically triggers penalty charges and interest. Repeated or willful failures can leave the responsible officers personally liable for the unremitted tax, and in some jurisdictions willful failure to withhold is a criminal offense. Most payroll providers build local compliance into their systems, but employers running payroll manually or operating in multiple municipalities need to be careful.
For individuals, penalties and interest vary by jurisdiction. Many localities model their structure on the federal approach: a percentage-based penalty for late filing (often around 5% of unpaid tax per month, up to a cap) plus separate interest on the outstanding balance.6Internal Revenue Service. Failure to File Penalty Some localities also impose flat-dollar penalties for late or unfiled returns, ranging from around $50 to several hundred dollars. Interest on underpaid local tax accrues from the original due date, and local rates tend to track federal rates loosely.7Internal Revenue Service.

The simplest way to stay clear of all of this is to confirm early in the year that your withholding actually covers your local liability, and to make estimated payments for any income your employer doesn’t withhold on.
