Filing a 1099-NEC for Subcontractors: The $290 Late Penalty Trap

You must file a 1099-NEC for any unincorporated subcontractor you pay $600 or more via cash, check, or bank transfer during the calendar year. The strict IRS deadline is January 31st, and missing it triggers late penalties up to $290 per form. Collect a signed W-9 before you cut their first check, or you will be scrambling at tax time.

If you are running a construction business, you are going to hire specialty trades. You bring in a drywaller to finish a basement, an electrician to wire a kitchen island, or a guy with a skid steer to grade a driveway. You pay them, you mark up their work, and you move on to the next job.

But the IRS does not let you just write off those expenses on a handshake. If you want to deduct the money you paid to subs from your gross revenue, you have to prove to the IRS exactly who you paid. That is what the 1099-NEC form does. It tells the government: "I paid this guy $8,500 for labor, so I am not paying taxes on that $8,500—he is."

If you screw up filing 1099 nec for subcontractors, the IRS can disallow your deduction. Suddenly, you are paying income tax on money you already gave to your drywaller. Add the late penalties on top, and a simple paperwork error can wipe out the profit margin on an entire job.

Here is how to lock down your W-9s, track your payments, and file your 1099-NECs without turning January into a bookkeeping nightmare.

The $600 Rule: Who Actually Gets a 1099-NEC?

The rule is straightforward, but the application is where contractors get confused. You must issue a 1099-NEC to a subcontractor if they meet all four of these conditions:

1. They are not your employee.
2. You paid them for services in the course of your trade or business (not for personal home repairs).
3. You paid them to an individual, partnership, estate, or LLC (not a C-Corporation or S-Corporation).
4. You paid them $600 or more during the calendar year.

The Corporate Exception

You do not send a 1099-NEC to a corporation. If you hire "Smith Plumbing, Inc." and they are registered as an S-Corp or a C-Corp, you do not owe them a 1099, even if you paid them $50,000.

However, if you hire "Dave's Drywall, LLC," you do owe them a 1099-NEC. A standard single-member LLC is treated as a "disregarded entity" by the IRS, meaning they are taxed like a sole proprietor.

The Material vs. Labor Split

Contractors constantly ask: "My framing sub gave me an invoice for $5,000. It was $2,000 for labor and $3,000 for lumber. Do I just 1099 him for the $2,000 labor?"

No. If the subcontractor provides the materials and includes them on the same invoice as the labor, you issue the 1099-NEC for the full $5,000. The subcontractor will deduct the $3,000 lumber cost on their own Schedule C tax return. It is not your job to separate their materials from their labor for IRS reporting.

The only time you separate it is if you buy the materials directly. If you put the $3,000 of lumber on your company Home Depot account, and only pay the framer the $2,000 for labor, then you issue a 1099-NEC for $2,000.

The Payment Method Loophole

This is a massive detail that saves contractors hours of paperwork: You only issue a 1099-NEC for payments made by cash, check, ACH, or direct bank transfer.

If you pay a subcontractor using a credit card, debit card, or a third-party settlement network like PayPal or Stripe, you do not issue them a 1099-NEC. The payment processor (e.g., Visa, Chase, PayPal) is responsible for reporting those transactions on a Form 1099-K. If you issue a 1099-NEC for a credit card payment, the IRS will think the sub made twice as much money as they actually did, and their CPA will be calling you angry.

Most Contractors Get This Wrong: The "Pay First, Ask Later" Mistake

Here is the most common mistake in construction bookkeeping: It is 4:00 PM on a Friday. The tile guy just finished the master shower. He wants his check so he can make payroll. You hand him a check for $3,500 and say, "Hey, email me your W-9 next week so my CPA has it."

He says, "No problem, boss."

You will never see that W-9.

When January rolls around, you will be calling him, texting him, and begging him for his Taxpayer Identification Number (TIN) or Social Security Number so you can file his 1099-NEC. He will ignore you, because he already has his money and he doesn't want to report the income.

The Rule: No W-9, no check. Period.

Make it a rigid company policy. When a subcontractor steps on your job site, they must hand you a completed Form W-9 and a Certificate of Insurance (COI). If they don't have it on Friday afternoon, they don't get paid on Friday afternoon. The moment you hand over the money, you lose 100% of your leverage.

The 24% Backup Withholding Weapon

If a subcontractor flat-out refuses to give you a W-9, you are legally required by the IRS to execute "Backup Withholding." This means you must withhold 24% of their payment and remit it directly to the IRS on their behalf.

Imagine telling your tile guy: "Since you won't give me a W-9, the IRS requires me to withhold 24% of your $3,500 invoice. Here is a check for $2,660. I am sending the other $840 to the IRS in your name."

Watch how fast he finds a pen to fill out that W-9. You do not want to actually deal with the administrative headache of remitting backup withholding, but knowing the law gives you the ammunition to force subs to comply with your paperwork requirements.

The IRS Penalty Trap: Real Numbers on What Late Filing Costs

The deadline for filing 1099 nec for subcontractors is January 31st. This is a hard deadline. You must send Copy A to the IRS by January 31st, and you must provide Copy B to the subcontractor by January 31st.

If you miss this deadline, the IRS assesses penalties based on how late you are. The penalties compound per form, which means if you have 15 subcontractors, the fines scale up aggressively.

• Up to 30 days late: ~$60 per form.
• 31 days late through August 1st: ~$120 per form.
• After August 1st or completely failing to file: Up to $290 per form.
• Intentional disregard: If the IRS determines you willfully ignored the filing requirement, the penalty jumps to a minimum of $580 per form, with no maximum cap.

Note: The IRS indexes these penalties for inflation annually, so the exact dollar amount shifts slightly each tax year, but the $290 tier is the standard baseline for a completely missed form.

If you have 20 subcontractors and you just "forget" to file until your CPA yells at you in October, you are looking at a $5,800 penalty. That is straight off your bottom line.

What This Looks Like on a Job

Let’s look at a practical scenario to see exactly how 1099-NEC rules apply in the field.

You are a General Contractor running a $150,000 kitchen and living room remodel. Here is who you pay over the course of the three-month job:

1. The Demolition Crew: "Smash Brothers, LLC"

• Entity: Single-Member LLC.
• Payment: $4,500 paid via company check.
• Action: You must issue a 1099-NEC for $4,500. They are an LLC (taxed as a sole prop), paid over $600, and paid via check.

2. The Electrician: "Current Solutions, Inc."

• Entity: S-Corporation.
• Payment: $12,000 paid via ACH bank transfer.
• Action: No 1099-NEC required. Because they are an S-Corp, they are exempt from 1099 reporting.

3. The Plumber: "Joe Smith (Sole Proprietor)"

• Entity: Sole Proprietor.
• Payment: $3,200 paid via Business Credit Card.
• Action: No 1099-NEC required. Because you paid with a credit card, the credit card processor will issue a 1099-K to Joe. If you issue a 1099-NEC, Joe will be double-taxed.

4. The Cleanup Guy: "Tommy's Trash Removal"

• Entity: Unregistered Sole Proprietor.
• Payment: $400 paid via cash.
• Action: No 1099-NEC required. The payment is under the $600 annual threshold. (Though you still need a receipt to deduct the $400 as a business expense).

This is why the W-9 is so critical. You cannot look at "Current Solutions, Inc." and know for a fact how they are taxed just by their name. The W-9 has a specific box where the subcontractor checks off whether they are a Sole Prop, C-Corp, S-Corp, or Partnership. That single checkbox dictates your bookkeeping workflow.

How to Collect W-9s Without Stalling the Job

Contractors hate paperwork, and subcontractors hate it even more. If you make the onboarding process difficult, good subs will go work for your competitors. You need a frictionless system.

1. Digitize the Process Stop carrying crinkled paper W-9s in the dashboard of your truck. Use software like DocuSign, HelloSign, or a construction management tool (like Buildertrend or Procore) to send a digital W-9 the moment you accept their bid. They can fill it out on their phone while sitting in their truck.

2. Bundle the Requirements You shouldn't just be collecting a W-9. You must also collect their Certificate of Insurance (COI) to prove they have general liability and workers' compensation coverage. If you don't, your insurance company will charge you for their labor during your annual audit.

Create a "Subcontractor Onboarding Packet." It should be a single PDF or digital link that says: "To get set up in our payment system, please complete this W-9 and have your insurance agent email your COI to [Your Email]."

3. The Bookkeeper Hand-off As soon as the digital W-9 comes in, input their details (Name, Address, EIN/SSN, Entity Type) directly into your accounting software (like QuickBooks Online or Xero). Check the box that says "Track payments for 1099." Do this immediately so you don't have to touch it again until January.

Step-by-Step: Filing 1099-NEC for Subcontractors

When January 1st hits, the clock starts ticking. You have 31 days to get this done. Here is the exact playbook to execute it flawlessly.

Step 1: The December Vendor Audit

Do not wait until January. In mid-December, open your accounting software and run a "1099 Vendor Report." This will show you every subcontractor you paid over $600 during the year.

Review the list. Are there any missing Tax IDs? Are there any missing addresses? Did you accidentally include a supplier who is a C-Corp? Fix these errors in December while people are still answering their phones, rather than during the chaotic final week of January.

Step 2: Choose Your Filing Method

The IRS is cracking down on paper filing. If you are filing 10 or more information returns (this includes W-2s, 1099s, etc. combined), you are legally required to e-file. If you try to mail in paper forms when you have more than 10, the IRS will reject them and hit you with penalties.

Even if you have fewer than 10, e-filing is vastly superior. Paper forms require ordering special red-ink scannable forms from the IRS (you cannot just print them on standard printer paper), and you have to mail them with a Form 1096 summary sheet.

Step 3: Use Software to E-File

You do not need a CPA to file 1099-NECs if your bookkeeping is clean. You have three main software options:

• Your Accounting Software: QuickBooks Online, Xero, and Gusto all have built-in 1099 filing features. You click a few buttons, pay a small fee (usually $15-$30 base plus $3-$5 per form), and the software e-files with the IRS and emails the copies to your subs.
• Third-Party E-File Services: If you use desktop software or spreadsheets, use a service like Track1099 or Tax1099. You upload an Excel sheet or connect your software, and they handle the e-filing and mailing for about $3-$4 per form.
• The IRS IRIS Portal: The IRS recently launched the Information Returns Intake System (IRIS). It is completely free to use. You have to apply for a Transmitter Control Code (TCC) to use it, which takes a few weeks, so set this up in November. It is clunkier than paid software, but it costs zero dollars.

Step 4: Distribute Copy B to Subcontractors

The IRS requires you to furnish "Copy B" to the subcontractor by January 31st. If you use a service like Track1099 or QuickBooks, they will email a secure link to the sub.

Important: You must have the subcontractor's consent to deliver their 1099 electronically. If they do not consent, or if they don't have an email address, you must mail a physical copy to their address via USPS. Most e-file software will offer a "print and mail" service for an extra $1.50 per form. Pay it. It is cheaper than buying stamps and envelopes yourself.

The Misclassification Danger Zone

Filing a 1099-NEC is only half the battle. The other half is ensuring the person you are giving it to is actually a subcontractor, not an employee in disguise.

The IRS and the Department of Labor are aggressively targeting the construction industry for worker misclassification. If you hire a "subcontractor," but you tell him to show up at 7:00 AM, you provide his tools, you pay him an hourly rate, and he only works for you, the IRS considers him an employee.

If you issue a 1099-NEC to someone who should be getting a W-2, you are committing tax fraud. The penalties for misclassification include paying back-taxes, uncollected FICA taxes, overtime wages, and massive fines.

Do not use a 1099-NEC as a tool to avoid paying payroll taxes. If you control how and when the work is done, they are an employee.

Subcontractor Liability & Margins

Handling the tax paperwork is just the administrative side of hiring subs. The business side is making sure you are actually profiting off their labor.

Many contractors hire a sub for $5,000, mark it up 10% to $5,500, and think they made $500. But by the time you factor in the administrative time to collect the W-9, the cost to file the 1099-NEC, the general liability insurance premium you pay on subcontracted costs, and the project management time, you actually lost money on that sub.

You must build administrative and liability costs into your markup.

State Filing Requirements

Do not forget about your state department of revenue. Filing the 1099-NEC with the federal IRS does not automatically satisfy your state requirements.

Many states participate in the Combined Federal/State Filing (CF/SF) program. If your state is in this program, and you e-file your 1099-NEC with the IRS, the IRS will automatically forward the data to your state.

However, several states (like California, Pennsylvania, and Oregon) have their own specific reporting requirements or do not participate fully in the CF/SF program for the 1099-NEC. If you operate in a state that requires direct filing, you must upload a separate file to your state's tax portal. If you use a reputable e-file software like Tax1099 or QuickBooks, they will usually prompt you and handle the state filing for an additional small fee. Always verify your local state laws with your CPA.

Next Steps

Do not wait until the third week of January to figure out who you paid.

Tomorrow morning, open your accounting software and run an "Expenses by Vendor" report for the current year. Filter it for any unincorporated trade you paid more than $600. Cross-reference that list with your W-9 folder.

For every vendor missing a W-9, send them an email right now. Tell them you are auditing your books for year-end and need their W-9 on file before any future invoices can be processed. Get the paperwork locked down now, and your January will be spent bidding new jobs instead of chasing down old tax IDs.
