State Withholding & Local Taxes

Rita came in with her part-time W-2 from a medical equipment company. She had been working a few days a week helping them organize records — light work, good hourly rate, ten miles from her house.

The preparer flipped to the bottom of the W-2. Boxes 15 through 20 were blank except for Box 15, which showed “FL” and a number.

“This looks straightforward,” the preparer said. “You worked in Florida, the company is in Florida, no state tax withheld — which is correct because Florida has no income tax. These boxes are essentially empty for you.”

Rita nodded. “My niece moved to Georgia last year and she said she pays state taxes every week.”

“Georgia has a state income tax. Florida doesn’t. That’s the difference. If you ever do work in a state that has an income tax, those boxes will have numbers in them, and we’ll need to deal with those on your return.”

The bottom section of the W-2 — Boxes 15 through 20 — covers state and local taxes. For most of your South Shore clients who live and work entirely in Florida, this section is largely blank. But you need to understand what those boxes mean, because some clients have income from other states, some employers operate across state lines, and some cities and counties impose local income taxes on top of state taxes.

Florida has no state income tax. This is one of the more significant facts about the market you’re working in. Your local clients who work local jobs will have blank state tax boxes on their W-2s. No Box 16 wages. No Box 17 withholding. The employer lists “FL” in Box 15 and the company’s state EIN, and that’s typically it.

This means for most of your Florida-resident W-2 clients, the state section is not a source of complexity. But “most” is not “all.” You will encounter exceptions regularly enough that you need to know how to handle them.

Box 15 — State and Employer’s State ID Number. The two-letter state abbreviation and the employer’s state tax identification number. Every employer lists the state or states where wages were earned. Some clients have employers who operated in multiple states and you’ll see multiple Box 15 entries on the same W-2 — the form allows two sets of state boxes side by side.

Box 16 — State Wages, Tips, Etc. The wages subject to state income tax. May differ from Box 1 because some states have different deduction rules. A state might not recognize the pre-tax treatment of certain benefits that reduce federal Box 1. In some cases Box 16 is higher than Box 1.

Box 17 — State Income Tax Withheld. The amount sent to the state government on the employee’s behalf. This is the state equivalent of Box 2. It goes on the state return as the pre-payment credit against state tax owed.

Box 18 — Local Wages, Tips, Etc. Wages subject to local income tax. Not all locations have local income taxes, but some cities, counties, and school districts do — particularly in Ohio, Pennsylvania, Kentucky, Indiana, and New York City, among others.

Box 19 — Local Income Tax Withheld. The amount withheld for local income taxes.

Box 20 — Locality Name. The name of the city, county, or other local taxing jurisdiction. If your client has a Box 18 or 19 amount, Box 20 tells you which locality it relates to.

This situation comes up more than you might expect. A Ruskin client takes a temporary assignment in Georgia. A local worker gets promoted and spends three months at a facility in North Carolina. A remote worker’s employer is based in New York and withholds New York tax.

When this happens, the W-2 shows wages and withholding for the other state in Boxes 15–17. Depending on the situation, the client may need to:

(1) File a non-resident return in the other state to claim back over-withheld tax or pay what’s owed.
(2) Claim a credit on the federal or Florida return for taxes paid to another state — though because Florida has no income tax, this credit typically doesn’t apply for Florida residents.
(3) Simply report the out-of-state withholding correctly on the return so the credit flows through properly.

Multi-state returns are covered in depth later in the curriculum. At this stage, recognize when you’re looking at one, understand what the boxes mean, and know that it requires additional attention.

Local income taxes are taxes imposed by a city, county, school district, or other local government — in addition to state income taxes. They are not common everywhere, but in certain states they are very common. Ohio cities like Columbus and Cincinnati have local taxes. Pennsylvania has thousands of local jurisdictions with earned income taxes. Kentucky and Indiana have local taxes in many counties. New York City residents pay city tax on top of New York State tax.

For your Ruskin and South Shore clients, local income taxes from Florida jurisdictions are essentially non-existent — Florida municipalities do not impose local income taxes. But if a client worked in one of these states or moved from one, Boxes 18–20 will have entries that need to go on a local return.

Some neighboring states have reciprocity agreements that allow residents of one state to pay income tax only to their home state, even when working in the other state. For example, a Maryland resident working in Virginia pays Maryland income tax, not Virginia income tax — because Maryland and Virginia have a reciprocity agreement.

These agreements matter when your client is a Florida resident who works in a state that has reciprocity with a nearby state. In practice, most Florida-based situations don’t involve reciprocity because Florida has no income tax and doesn’t enter into these agreements. But if you have a client who lived in a state with reciprocity before moving to Florida and still has withholding from that situation, you need to know what a reciprocity agreement does before you can handle the return correctly.

Reciprocity does not mean no tax — it means tax to the home state only. If a client has withholding from a state they don’t live in and those states have a reciprocity agreement, the non-resident withholding may need to be refunded through a non-resident return, and the income taxed by the home state instead.

Full multi-state return preparation is a later curriculum topic. At this stage: recognize reciprocity situations when they appear, ask the right questions, and know when a situation is beyond basic W-2 prep.
