Multiple W-2s

Marcus dropped three envelopes on the desk.

“Two jobs and an Uber thing,” he said.

The preparer opened each one. Amazon W-2. A staffing agency W-2 from a two-month contract job in the spring. And a 1099-K from Uber.

“You know you’re going to owe this year,” she said. Not a question.

Marcus leaned back. “I figured. The Uber thing again?”

“The Uber thing — yes. But also the staffing agency. Look at Box 2 on this W-2.” She turned it toward him. Box 2 showed $0.

“They didn’t withhold anything?”

“Not a dollar. So you worked there for two months, made $8,400 — and the IRS got nothing on it all year. That alone adds $840 to your balance.”

Multiple W-2s are common. People change jobs, work two jobs simultaneously, pick up contract work, or have a side situation that generates its own W-2. Each one requires attention. And when you have multiple income sources — whether they’re all W-2s or a mix of W-2s and 1099s — the withholding situation gets complicated in ways most clients don’t see coming.

Here’s the fundamental issue: each employer withholds based on the assumption that their job is the employee’s only job. They look at the W-4, calculate what the employee earns from them, and set the withholding rate accordingly.

But tax brackets work on total income. If Employer A pays $32,000 and withholds at a rate appropriate for $32,000, and Employer B pays $20,000 and withholds at a rate appropriate for $20,000 — neither employer knows about the other. The total income is $52,000, which puts some of that income in a higher bracket than either employer accounted for. Result: under-withholding, and a balance due in April.

Each W-2 is entered separately in the tax software. The software totals the wages and withholding from all W-2s automatically. You do not add them together manually before entering — you enter each W-2 as its own record. The 1040 shows the combined wages on Line 1a through a worksheet, with each employer’s information documented separately.

When you have all the W-2s in front of you, do a quick sanity check

Sometimes a W-2 shows wages in Box 1 but $0 in Box 2. This happens when an employee filled out their W-4 incorrectly, claimed too many allowances, or — in some cases — the employer simply failed to withhold. It can also happen with certain types of compensation where withholding is unusual or where the employee specifically requested $0 withholding.

Before you enter a single W-2, establish how many W-2s the client should have. Ask:

“How many jobs did you have this year?”
“Did you receive a W-2 from each one?”
“Did you do any work where you got paid without a W-2 — any contract work, gig platforms, or cash jobs?”

Clients frequently forget a job they only worked for two months in the spring. They forget the holiday retail job. They don’t realize the staffing agency sends a separate W-2 from the company where they placed them. Always verify the count before you start.

A W-2 means the person was an employee. The employer withheld FICA and possibly income tax. A 1099-NEC means the person was a contractor. No withholding. Self-employment tax applies.

Some clients receive a W-2 from one job and a 1099-NEC from another. Some receive both from the same company if they did both employee and contractor work. Confirm what each document is before entering it. Entering a 1099-NEC as a W-2 skips the self-employment tax calculation, which is a significant error.
