Meta description: Most 1099 filing errors aren't tax mistakes, they're workflow failures. Asure explains who requires a 1099 and how to build a repeatable compliance system.
Most 1099 filing errors at scaling companies are not tax mistakes. They are workflow failures. The IRS rules on who requires a 1099 are settled, and the failure point is the absence of a repeatable system to apply them before year-end. The obligation decision gets made upstream, months before the paperwork does, whether or not anyone notices at the time.
The 1099 Decision Is Made Upstream, Not at Year-End
By the time an accounts payable team sits down in January to sort out who needs a 1099-NEC, the decision has usually already been made, just not on purpose. It was made in March, or June, or September, when a new vendor was added to the system with an invoice number and a payment amount but no signed W-9 and no record of whether the business was a sole proprietorship, a partnership, or a corporation. The year-end scramble that follows, the vendor outreach, the missing addresses, the "can you resend your W-9" emails sent three days before the filing deadline, is not a tax problem. It is the visible symptom of a data problem created months earlier.
Was the rule unclear? Rarely. Most operators can recite the basics: pay a non-corporate vendor for services, cross the threshold, file a form. What is missing is not knowledge of the rule. What is missing is a system that captured the information needed to apply the rule at the moment the vendor relationship began.
The cost of that gap is not abstract. For information returns required to be filed in 2027, covering 2026 payments, the penalty for filing an incorrect or late Form 1099 runs $60 per return if corrected within 30 days of the due date, $130 per return if corrected after that window, and $340 per return under the general rule if it is not corrected at all. If the failure is deemed intentional disregard of the filing requirement, the penalty jumps to the greater of $690 or 10% of the amount required to be reported, with no cap, per IRS Revenue Procedure 2025-32. Multiply any of those figures by a vendor list that has grown from dozens to hundreds as the business has scaled, and the arithmetic on a missed classification stops being trivial.
None of this requires a deep read of IRS Publication 1220, the electronic filing specifications document that governs how information returns move to the agency once volume requires it. That is infrastructure, not judgment. The judgment happens earlier, at the point of vendor setup, and it is either built into the workflow or it is not.
The pattern shows up consistently across growing companies: the filing problem that surfaces in January was created in July, when a vendor was onboarded without a completed W-9 on file. The fix is not a better year-end checklist. It is a decision, made once, about when classification gets captured, and a process that enforces it every time a new vendor is added, regardless of how busy the AP team is that week.
That decision rests on three variables, and understanding them before a single vendor is onboarded is what turns a recurring scramble into a solved problem.
Three Variables Determine Every 1099 Obligation, and Only One Is the Threshold
Every 1099 obligation, regardless of industry or vendor type, reduces to three variables, the payee's entity type, the category of payment, and the cumulative dollar amount paid during the calendar year. Most compliance failures trace back to getting one of the first two wrong, not the third, even though the threshold gets the most attention.
Start with the threshold, since it just changed. For payments made after December 31, 2025, the reporting threshold for Form 1099-NEC and 1099-MISC rises to $2,000, the first increase since the $600 figure was set in 1954, under the IRS Instructions for Forms 1099-MISC and 1099-NEC as revised for the One, Big, Beautiful Bill Act. As of August 2026, $2,000 is the threshold that governs vendor payments made in 2026 and beyond; $600 was the operative figure for 2025 payments, the filing season that just closed. An AP team still budgeting for $600 as the trigger will misclassify vendors on the low end of the spend range in both directions.
The threshold is also cumulative per calendar year across every payment made to that payee, not per invoice or per project. A vendor paid $400 in March, $700 in July, and $1,200 in November crossed the $2,000 mark in November, and the obligation applies to the full-year total, not just the payments made after the line was crossed.
Entity type is the variable that does the most damage when it is wrong, because it determines whether the threshold question is even relevant. A rough reference, organized by how a payee typically shows up on a signed W-9, looks like this.
- Sole proprietors and single-member LLCs are generally reportable for services once the threshold is met, since a single-member LLC is disregarded for tax purposes and treated as its owner unless it elected corporate treatment.
- Multi-member LLCs taxed as partnerships are generally reportable in the same way, since a partnership is not a corporation for reporting purposes.
- LLCs that elected S-corp or C-corp tax treatment are generally treated as corporations and fall under the corporate exemption, along with the same exceptions that apply to any corporation.
- C-corps and S-corps are generally exempt from 1099-NEC reporting, with the attorney and medical-payment overrides covered in the next section.
- Attorneys and law firms are reportable regardless of entity type, a point significant enough to warrant its own section.
- Nonprofits and government agencies are generally exempt, though documentation still matters.
The only mechanism that reliably surfaces which category a vendor falls into is Form W-9. A vendor's name, invoice format, or its own assumption about its tax status is not a substitute for the entity classification the vendor certifies on that form. Operators who treat the W-9 as a payment prerequisite, not a year-end cleanup task, rarely face the entity-type ambiguity that drives most 1099 errors, because the question got answered before it mattered.
Entity type is the most consequential variable to get right, but payment category introduces its own exceptions, and this is where the widely held belief that "corporations don't get 1099s" starts to fail.
The Corporate Exemption Has Three Exceptions Scaling Companies Routinely Miss
The general rule is real. Payments to C-corps and S-corps are generally exempt from 1099-NEC and 1099-MISC reporting. Most AP teams know this rule and apply it correctly in the ordinary case. The problem is that "generally exempt" has three specific overrides, and scaling companies miss them often enough that they deserve to be treated as their own category of risk, not a footnote.
The first override covers attorney fees. Payments to an attorney or law firm for legal services are reportable on Form 1099-NEC once they cross the threshold, regardless of whether the attorney or law firm is incorporated. The IRS Instructions for Forms 1099-MISC and 1099-NEC state it plainly, the exemption from reporting payments made to corporations does not apply to payments for legal services. An incorporated law firm is still a reportable payee for its fees.
The second override covers gross proceeds paid to attorneys, reported on Form 1099-MISC, Box 10, separate from the fees themselves. This applies even when the payment is not compensation for the attorney's own services, such as a settlement disbursed through an attorney's trust account, and it applies regardless of the attorney's corporate status.
The third override covers medical and health care payments. Payments to a physician, clinic, or other health care provider for services are reportable under the same instructions, again regardless of whether the provider is incorporated, which surprises AP teams that have internalized "corporation means no 1099" as an absolute rule rather than a general one.
Of the three, the attorney-fees override is the single most commonly missed obligation in B2B payables. Legal spend often runs through a general "professional services" vendor code with no flag distinguishing it from consulting or advisory fees paid to an actual corporation that is properly exempt. It is the highest-risk line item in vendor-payment classification, precisely because it is the exception that experienced operators, the ones who have the general corporate rule down cold, most often assume does not apply to them.
Advertising and sponsorship payments raise a version of the same question, though they do not require a separate rule. The determining factor is not the label on the invoice. It is whether the payment is for services and what the payee's entity type is. A corporate sponsor or ad vendor is generally exempt, absent the overrides above. A non-corporate payee, a freelance marketer, an unincorporated event promoter, a sole-proprietor social media consultant, paid for services over the threshold is reportable, whether the line item says "advertising," "sponsorship," or "marketing services." The word on the invoice does not change the analysis. The entity type and payment category do.
None of these exceptions require new software or a new form. They require the classification decision to be made correctly once, at the point a vendor enters the system, which is the same discipline the W-9 exists to enforce.
The W-9 Is the Compliance System, Not a Form You Collect When You Remember
Form W-9 is not paperwork. It is the mechanism that answers all three questions a 1099 obligation depends on in a single document, the payee's taxpayer identification number, its entity type, and its tax classification. Every reference point, every entity-type exception, every threshold calculation in the two sections above depends on information that lives on that form. A vendor file without a signed W-9 is a vendor file with an unresolved compliance question, whether or not anyone has noticed yet.
The stakes of an incomplete or incorrect W-9 go beyond a scramble to reissue a form. A missing or incorrect taxpayer identification number triggers backup withholding at 24% of the payment, per IRS backup withholding guidance. That obligation can also arise after the IRS notifies a payer, through a CP2100 or CP2100A notice under the withholding certification rules at 26 CFR Section 31.3406(d)-5, that a payee's name and TIN do not match agency records. Either way, the payer holds the withholding obligation until the mismatch gets resolved, which makes an unverified W-9 a live financial exposure, not a paperwork gap.
The operational question is not whether to collect a W-9. Almost every finance team already does, eventually. The question is when. Three points in the vendor lifecycle compete for the job, before the first payment goes out, during a broader onboarding cleanup a few weeks in, or during a year-end push once the AP team realizes how many gaps exist. Only one of those three actually prevents the problem instead of managing it after the fact.
Asure's bias, built from years of running payroll tax filing and HR compliance work for growing companies, is unambiguous. The W-9 is a payment prerequisite, not a compliance afterthought. Collect it before the first check, wire, or card payment goes out, not during onboarding cleanup and not at year-end. Teams that enforce this rule eliminate most of their 1099 exposure before it has a chance to accumulate, because the classification question gets answered when there is exactly one vendor to deal with, not hundreds.
Even a team that gets the W-9 timing right still runs into a second structural challenge as the business scales, tracking how much a given vendor has actually been paid, in total, across every payment method the company uses.
Scaling Payables Breaks 1099 Compliance in Predictable Ways, and the Fixes Are Structural
Growth does not make 1099 compliance harder in a random way. It breaks it in three specific, predictable places, and each one has a structural fix rather than a procedural one.
The first failure mode is payment fragmentation. A vendor paid partly by ACH, partly by paper check, partly on a corporate card, and partly through a bill-pay platform has its cumulative annual total spread across systems that do not talk to each other. No single ledger shows the $2,000 threshold being crossed, so nobody notices until someone manually reconciles multiple data sources during filing season. The structural fix is not more reconciliation. It is a single vendor-level ledger that aggregates payment amounts across every payment method as they happen, so the cumulative total is always current rather than reconstructed after the fact.
The second failure mode is a gap in vendor master data. Entity type and W-9 status are treated as attributes to collect eventually rather than required fields captured at the moment a vendor record is created. A vendor master file that allows a new vendor to be added, and paid, without those two fields populated is a file that will generate a year-end scramble by design, not by accident. The fix is making the fields mandatory at intake, not optional.
The third failure mode is the year-end classification scramble itself, the point where an AP team tries to retroactively determine 1099 status for a vendor list that has grown from dozens to hundreds, often under a filing deadline. Retroactive classification at volume is slow and error-prone in a way that classification at the point of onboarding, one vendor at a time, is not.
Two regulatory trends make this fragmentation more consequential as vendor count grows, not less. The Form 1099-K threshold for third-party settlement organizations reverted to $20,000 in gross payments and more than 200 transactions, per IRS Newsroom release IR-2025-107, which changes what a payment platform itself reports and adds another layer for a growing AP team to reconcile against its own 1099-NEC obligations. And the e-file mandate now applies once a business is required to file 10 or more information returns in a calendar year, aggregated across every return type rather than counted separately per form, according to the IRS General Instructions for Certain Information Returns, effective for returns required to be filed on or after January 1, 2024. A company with even a modest vendor list crosses that line quickly.
Growing companies that get W-2 payroll onboarding right already practice a version of this discipline. AsureCentral and AsureWorks both build new-hire tax elections, direct deposit setup, and classification data into the hiring workflow itself, captured before the first paycheck goes out rather than reconstructed later. Vendor 1099 compliance runs through AP and vendor master data rather than payroll or HR systems, and Asure does not process vendor 1099 filings directly, but the underlying discipline transfers: decide the classification once, upstream, rather than reconstructing it under a filing deadline.
Bottom Line
1099 compliance at scale is not a tax-knowledge problem. The rules on entity type, payment category, and the threshold are documented and stable enough to apply consistently. What breaks as a company scales is the workflow, the upstream decision to capture a vendor's classification before the first payment, the discipline to treat the corporate exemption's exceptions as routine rather than surprising, and the structural capacity to track cumulative spend across payment methods instead of reconstructing it in January.
The practitioner implication is straightforward. Operators who build W-9 collection and vendor classification into onboarding, not year-end, convert a recurring compliance risk into a solved operational problem rather than an annual fire drill.
Asure applies this same upstream, systems-first discipline to its own lane, payroll tax filing and HR compliance, today through AsureCentral and AsureWorks: new-hire classification and tax data are captured at onboarding, not reconstructed at year-end. Vendor 1099 compliance sits outside that product scope, but the same discipline applies wherever a business tracks who it pays: the classification decision belongs at onboarding, not at the year-end deadline.
Related Questions
Do You Have to Send a 1099 to an LLC?
It depends on the LLC's tax classification, not the "LLC" label itself. Single-member LLCs (disregarded entities) and multi-member LLCs taxed as partnerships are reportable once cumulative payments for services reach $2,000 for 2026 payments and after ($600 applied to 2025 payments). LLCs that elected S-corp or C-corp tax treatment are generally treated as corporations and fall under the corporate exemption. The W-9 is the only reliable way to confirm which category applies, since an LLC's name alone does not indicate its tax status.
Do You Have to Send a 1099 to a Corporation?
The general corporate exemption applies, exempting most C-corp and S-corp payees from 1099-NEC and 1099-MISC reporting. Two exceptions override it regardless of incorporation, payments for attorney fees or gross proceeds to attorneys, and medical or health care payments, per the IRS Instructions for Forms 1099-MISC and 1099-NEC. Verify entity type and payment category through a signed W-9 before assuming a corporate payee is automatically exempt.
Do You Have to Send a 1099 to Attorneys?
Yes, without exception for entity type or incorporation status. Attorney fees for legal services are reportable on Form 1099-NEC once cumulative payments reach the threshold, and gross proceeds paid to attorneys are separately reportable on Form 1099-MISC, Box 10, per the IRS Instructions for Forms 1099-MISC and 1099-NEC. This is the single most commonly missed override to the corporate exemption in B2B payables.
Do You Have to Send a 1099 to a Nonprofit or 501(c)(3)?
Generally exempt. Most nonprofits and 501(c)(3) organizations are treated similarly to corporations for reporting purposes on payments for services. A signed W-9 documenting the organization's tax-exempt status should still be collected and kept on file, so the exemption is documented rather than assumed.
Do You Have to Send a 1099 for Advertising or Sponsorship Payments?
It depends on the payee's entity type and whether the payment is for services, not on the word "advertising" appearing on the invoice. A corporate payee is generally exempt, absent the attorney or medical-payment overrides. A non-corporate payee, such as a sole proprietor or unincorporated promoter, is reportable once cumulative payments for services cross the $2,000 threshold for 2026 payments and after.
Do You Have to Send a 1099 to a Government Agency?
No. Government agencies fall outside the 1099 reporting requirement. Document the exemption with a W-9 or equivalent record the same way you would for any other payee, so the file shows why no 1099 was issued rather than leaving a gap.
