How do I file W-2 forms for my employees?

First: what “filing W-2s” usually includes

W-2 filing is usually two parts: (1) printing or delivering W-2 forms to your employees, and (2) sending the W-2 information to the IRS (and possibly your state) by the deadline.

Most small and mid-size businesses do this through a payroll service. A payroll service can calculate wages and withholding from your payroll runs, generate W-2 forms, file what’s required, and help with corrections when needed.

Important: RunWise Pay is a FREE matching service. We don’t run payroll, file W-2s, or give tax advice. For specifics about your situation, confirm details with a qualified payroll provider, accountant, or tax professional—and check the current IRS/state rules and deadlines.

The practical W-2 process (step by step)

1. Gather year-end payroll records from your payroll system (or your accountant/bookkeeper if needed).

2. Make sure every payroll run for the year is entered correctly (including pay frequency, pay types like wages/bonuses, and any required withholding).

3. Ask your payroll service (or provider) to produce W-2 forms for each employee. These forms should reflect the right wage amounts and federal/state/local withholding.

4. Review W-2s for accuracy before they’re finalized. Check employee names, addresses, and totals—small typos can create headaches.

5. Deliver employee copies by the required date, usually by January for the previous tax year.

6. File the employer copy with the IRS (often electronically). Your state may also require separate filing—rules vary by state.

If you’re doing this for the first time, don’t guess—ask a payroll service what they include for W-2 generation and filing, and confirm it in writing.

Deadlines and common “gotchas”

Deadlines can change, and they vary based on whether you file electronically and on IRS/state requirements. For the most current dates, confirm directly with the IRS and your state.

Common issues that delay or create corrections include:

• Missing or late payroll runs for the year
• Wrong employee addresses or legal names
• Incorrect classification of workers (employee vs. contractor)
• Off-cycle payments or retroactive pay not entered correctly
• Forgetting state/local W-2 reporting requirements (if your state requires it)

If you do need to correct a W-2 later, the process and deadlines can be strict. A payroll provider that handles W-2 corrections can be worth it—just confirm what they cover and what their support looks like.

How much does W-2 filing usually cost?

Cost depends on your team size, pay frequency, how many states you pay in, and what the provider includes (for example: W-2 processing, filing, corrections, and employee access to pay documents).

As a general guide, many payroll providers charge a monthly base fee plus a per-employee fee. For W-2 year-end work, some providers include it in their plan, while others may price it as part of the overall payroll service. If you’re comparing options, ask for a full breakdown of monthly costs and any year-end charges.

These ranges are not quotes. Get a written quote or written scope of work before you switch providers. Be extra careful with pricing that isn’t clear—especially anything that sounds “cheap” but isn’t transparent about year-end filings.

W-2 help: choosing a payroll provider (red flags to avoid)

If you’re matching with a payroll service through RunWise Pay, you stay in control. You compare options, confirm what’s included, and choose who to hire.

Red flags to watch for when someone offers W-2 handling:

• Vague pricing (“we’ll see what it costs”) with no clear year-end scope
• Hidden fees for W-2 printing, employee delivery, or corrections
• No clear tax/W-2 filing support or “we can’t guarantee” responsiveness
• Poor customer support (especially around year-end when you need fast answers)
• Pressure to sign quickly without a written list of what they will do

Before you sign, ask for a written checklist that covers:

• W-2 form creation and employee delivery method
• IRS filing method (and whether it’s electronic)
• Whether they handle state/local W-2 filing
• What happens if an employee’s info is incorrect
• W-2 corrections: how they’re handled and any extra cost

Also, confirm they can work with your current payroll setup and pay history. Rules and timelines vary by state and can change—so make sure you’re using the latest requirements.

If you’re new to US payroll: who does what?

A payroll service typically runs your pay calculations and produces year-end documents like W-2s based on your payroll activity.

An accountant or tax professional usually helps with broader tax planning, bookkeeping, or questions specific to your business. They can also advise on classification issues and recordkeeping.

RunWise Pay is not a tax advisor and not a payroll provider. Our role is to connect you with payroll services that can handle payroll processing and W-2s. If you want to explore options, start at services to learn what payroll providers commonly include, and then use RunWise Pay (free for you) to match based on your state, team size, and preferred language.
