The Ultimate 1099 Guide: Contractors, Vendors, LLCs & Amazon 1099-K Explained

Look, I get it. Tax season rolls around (tis the ecommerce tax season), and suddenly everyone's scrambling asking "what do I need to issue a 1099?" It's one of those business responsibilities that seems straightforward until you're knee-deep in paperwork wondering if you're doing it right.

After helping so many businesses navigate their tax obligations, I've seen every 1099 mistake in the book. The good news? Once you understand the system, it's actually pretty manageable. Let me walk you through everything you need to know about sending 1099 to contractors, handling vendors, and yes, even that confusing Amazon 1099 K form that keeps showing up in your mailbox.

What Exactly Is a 1099 Form?

Think of a 1099 as the IRS's way of keeping tabs on money flowing through the economy. It's an information return that tells the government "Hey, we paid this person money for services."

For most business owners, you'll deal with three main types:

1099-NEC (Nonemployee Compensation): This is your bread and butter for independent contractors. If you paid someone $600+ for services, you'll likely need this (after December 31, 2025, the threshold will be increased to $2,000).

1099-MISC: For miscellaneous payments like rent to landlords or certain legal settlements, with the changes noted above from payments after December 31, 2025.

1099-K: The one payment processors like Amazon, PayPal, and Stripe send to you for transaction volume. This was also recently changed, reverting back to the 200 transaction + 20K minimal threshold.

The $600 threshold is crucial here. Cross that line with any 1099 vendor, and you're in reporting territory. And keep abreast of changes. Because they are coming.

What Do I Need to Issue a 1099? The Essential Checklist

Here's where businesses often trip up. You can't just decide to send a 1099 on January 30th—you need the right information, and getting it requires planning ahead.

For every 1099 vendor, you need:

• Their legal name (exactly as it appears on their tax return)
• Current business address
• Taxpayer Identification Number (TIN)—either SSN, ITIN, or EIN
• Total amount you paid them during the tax year

Pro tip from the trenches: Get every contractor to fill out Form W-9 before you start working together. I can't tell you how many frantic calls I get in January from business owners trying to hunt down SSNs from contractors who've gone radio silent. Don't be that person.

Do Limited Liability Companies Receive 1099s?

This question trips up more business owners than almost any other 1099 issue, and honestly, the answer isn't as simple as you'd expect.

The short answer: It depends on how the LLC is taxed.

The longer answer: If the LLC is taxed as a sole proprietorship or partnership, then yes, you need to send them a 1099 for payments over $600. But if they're taxed as an S-Corp or C-Corp, you're off the hook.

Here's the kicker: There are exceptions even for corporations. Law firms and medical providers must receive 1099s regardless of their business structure. The IRS wants to track every dollar flowing to lawyers and doctors, apparently.

This is exactly why that W-9 form I mentioned earlier is so critical. It tells you not just their TIN, but also their tax classification. No guessing required.

Who Actually Counts as a 1099 Vendor?

The IRS casts a pretty wide net here. Your typical 1099 vendors include:

• Marketing agencies and consultants
• Accountants and bookkeepers (though hopefully you're working with us at Finaloop!)
• Web developers and SEO specialists
• Copywriters and content creators
• Fulfillment centers and logistics providers
• Real estate agents
• Landlords for office or warehouse rent

Critical distinction: These are all service providers. You don't issue 1099s for inventory purchases or product costs. If you bought 1,000 units of product from a supplier, that's a purchase, not a 1099 situation.

Also—and this should go without saying but I'll say it anyway—employees get W-2s, not 1099s. Misclassifying employees as contractors is a fast track to IRS trouble you don't want.

1099 Filing Deadlines (Miss These at Your Own Risk)

January is crunch time for 1099s, and the deadlines are non-negotiable

Filing Deadlines for Form 1099-MISC

• January 31: Furnish Copy B to recipients (i.e., contractors, vendors, or payees) for most types of payments reported on 1099‑MISC, including rents, royalties, prizes, medical payments, etc.
• February 28 (if filing on paper) / March 31 (if electronic): File Copy A (with the IRS) for all Form 1099‑MISC submissions, regardless of the payment type.
• February 15 (or next business day): Use this deadline only if you're reporting solely in Box 8 (substitute payments in lieu of dividends/interest) or Box 10 (gross proceeds paid to an attorney). This applies to delivering the recipient’s statement (Copy B)—not filing with the IRS

1099-NEC Filing Deadlines

• Due Date: January 31 — whether paper-filed or electronically submitted, Copy A (IRS filing) and Copy B (recipient’s copy) must both be delivered by this date. This applies regardless of the filing method.‍
• No Automatic Extension: The IRS does not grant an automatic extension for filing Form 1099‑NEC. Any extension requests must meet specific criteria

You can request an extension using Form 8809, but here's the catch—it only extends your filing deadline with the IRS, not the deadline for getting forms to your contractors. They still need their copies by January 31st.

The Cost of Getting It Wrong

Let me be blunt about penalties because they add up fast:

• $60 per form if you're up to 30 days late
• $130 per form if you're 30+ days late (but before August 1st)
• $330 per form if you file after August 1st
• $660 minimum per form if the IRS thinks you're intentionally ignoring the rules

I've seen small businesses get hit with thousands in penalties over missed 1099s. It's completely avoidable with proper planning.

The Amazon 1099 K Form: What ecommerce Sellers Need to Know

If you're selling on Amazon, you've probably received an Amazon 1099 K form and wondered what to do with it. This form reports gross payment volume processed through Amazon's system.

Here's what you need to understand: The 1099 K form Amazon sends you shows gross sales, not net profit. It doesn't account for:

• Amazon fees
• Returns and refunds
• Cost of goods sold
• Shipping costs
• Any other business expenses

This means your Amazon 1099 K form will likely show a much higher number than your actual taxable income. You'll need to reconcile this against your books to report the correct figures to the IRS.

The reporting thresholds have been changing, too (reinstating the 200 transactions + $20K threshold). More sellers are receiving these forms now, so don't panic if it's your first time seeing one. Just make sure your bookkeeping is solid so you can properly report your actual profit, not the inflated gross sales figure.

My System for Managing 1099 Vendors Like a Pro

After years of helping businesses streamline this process, here's what actually works:

1. Set up your systems in January, not December. Create a simple spreadsheet or use accounting software to track contractor payments from day one.

2. Collect W-9s religiously. No exceptions. No "I'll get it later." Get it before the first payment.

3. Flag the $600 threshold. When any 1099 vendor approaches $500 in payments, make a note. You'll need to prepare their 1099.

4. Separate services from products. Your inventory suppliers don't need 1099s, but your fulfillment center might.

5. Start preparing forms in early January. Don't wait until the 30th. Give yourself time to chase down missing information.

The Bottom Line

Managing your 1099 obligations doesn't have to be a nightmare. With the right systems and a little advance planning, you can handle sending 1099 to contractors and managing all your 1099 vendors without breaking a sweat.

The key is treating this as an ongoing business process, not a once-a-year scramble. Whether you're dealing with a simple service provider or trying to make sense of that Amazon 1099 K form, the fundamentals remain the same: good record-keeping and proper planning.

Remember, this 1099 guide covers the basics, but every business situation is unique. When in doubt, consult with a tax professional who understands your specific industry and circumstances. Your future self (and your bank account) will thank you for getting this right from the start.
