How Do I Know If I Have to File City Taxes?

In addition to federal and state taxes, some individuals must pay a local, or city, income tax. These municipal taxes are separate obligations with their own regulations and forms, and they fund local services like police departments, schools, and public works. Understanding whether you must file a city tax return depends on where you live, where you work, and the type of income you earn. Because the rules vary significantly between cities, you must assess your specific situation each year.

Primary Filing Triggers: Residency and Workplace

Your duty to file a city income tax return is determined by your residency status and physical work location. The primary rule is based on residency. If your permanent legal address, or domicile, is within a city that imposes an income tax, you are considered a resident and must file a return. As a resident, you are typically taxed on all of your earned income, regardless of whether you earned it inside or outside the city limits.

A separate filing obligation is triggered by where you earn your income, which applies to non-residents. If you live in a town with no local income tax but commute to a job in a city that does have one, you are usually required to file a non-resident return with that city. In this scenario, you only pay tax on the wages and compensation earned for work physically performed within that city’s borders.

An individual might live in one taxing city while working in another. To prevent double taxation, most municipalities offer a tax credit. The city where you live will typically grant you a credit for the taxes you were required to pay to the city where you work. This credit is often limited to the amount of tax your home city would have charged on that same income, meaning you ultimately pay the higher of the two tax rates.

Income Subject to City Taxation

Municipalities primarily tax earned income. This includes wages, salaries, tips, bonuses, commissions, and other forms of employee compensation. For self-employed individuals, the net profits from a business or profession conducted within the city are also taxable. Rental income from property located within the city is another common source of taxable income.

Conversely, many forms of unearned income are commonly exempt from city taxation. These exemptions often include interest and dividend income, Social Security benefits, pensions, annuities, and unemployment compensation. Military pay and capital gains are also frequently exempt. These exemptions are not universal and can differ between municipalities, so you must check the specific rules for the city in question.

Some cities also have specific rules for certain types of compensation. For example, employer contributions to health savings accounts or the value of group-term life insurance plans over $50,000 may be considered taxable by some local jurisdictions. Severance pay and certain disability benefits received through an employer’s wage continuation plan can also be subject to local tax.

Information Needed to Assess Your Filing Duty

To determine your city tax obligations, you must gather several documents. The most important is your Form W-2, Wage and Tax Statement, from each employer. You will also need any Forms 1099-NEC or 1099-MISC if you performed work as an independent contractor, as well as a detailed profit and loss statement if you operate your own business.

When reviewing your Form W-2, pay close attention to the bottom section. Box 18 shows the total amount of your wages that are subject to local income tax for that specific job. Box 19 reports the total amount of local income tax that was withheld by your employer, and Box 20 identifies the name of the locality to which those taxes were paid. If these boxes are filled in, it is a strong indicator that you may need to file a return.

Beyond tax forms, you will need your complete address history for the tax year, including the specific dates you lived at each location. This is necessary to establish your residency status for the entire year. You must also have the full physical address of every location where you worked to correctly allocate your earnings if you worked in multiple tax jurisdictions.

Locating Specific City Tax Rules and Forms

Finding the official tax regulations and forms for a particular city requires online research. The most reliable starting point is an online search engine, using specific queries like “[City Name] department of revenue,” or “[City Name] income tax division.” These searches should direct you to the official municipal government body responsible for administering the local tax.

When you find a potential source, verify that it is the city’s official government website, which typically ends in a .gov domain. Be cautious of third-party websites that offer tax forms or advice, as they may contain outdated or inaccurate information. The city’s official portal is the definitive source for the most current tax rates, rules, and forms.

Many municipal tax websites provide frequently asked questions (FAQs), taxpayer guides, and specific forms for both “Residents” and “Non-Residents.” Downloading forms and instructions directly from the official city website ensures you are complying with the latest requirements and using the correct documents for the specific tax year.
