--- name: form-1099-nec title: Form 1099-NEC — Nonemployee Compensation description: 'Use this skill when a US business needs to issue Form 1099-NEC to a nonemployee (contractor, freelancer, gig worker, vendor) for services, OR when a recipient receives a Form 1099-NEC and needs to report it on Schedule C / Schedule 1. Triggers on phrases like "Form 1099-NEC", "issue 1099 to contractor", "report contractor payments", "received 1099-NEC", "1099-NEC threshold", "$2,000 1099 threshold", "1099 for freelancer", "nonemployee compensation reporting", "backup withholding on 1099-NEC". Do NOT use for: W-2 employees (use payroll-tax skills, not this — different form, different rules); rent payments to a landlord (use `form-1099-misc` Box 1); royalty payments (use `form-1099-misc` Box 2); gross proceeds paid to an attorney, such as settlement funds (use `form-1099-misc` Box 10; attorneys'' fees for legal services DO go on 1099-NEC); third-party-network platform payments (use `form-1099-k` — Stripe, PayPal, Venmo, etc. issue 1099-K, not 1099-NEC); interest / dividends (use 1099-INT / 1099-DIV); cancellation-of-debt income (use `form-1099-c`).' author: jupid-tax author_url: https://github.com/jupid-tax/jupid-skills/tree/main/forms/form-1099-nec license: MIT version: 0.1.2 execution_mode: open jurisdiction: us practice: tax language: en sources: - title: Backup withholding path: references/backup-withholding.md - title: Common mistakes path: references/common-mistakes.md - title: Line by line path: references/line-by-line.md - title: Payee classification path: references/payee-classification.md - title: Threshold rules path: references/threshold-rules.md --- # Form 1099-NEC — Nonemployee Compensation This skill produces an audit-grade plan for Form 1099-NEC, on either side of the form: - **Payor side** (a business that paid contractors): determine whether a 1099-NEC is required for each payee, gather W-9 data, populate the boxes, file with the IRS, and deliver a copy to the recipient by January 31. - **Recipient side** (a contractor who received a 1099-NEC): reconcile the form against records and report the income on Schedule C (if business) or Schedule 1 Line 8 (if a one-off, non-business gig), with Box 4 federal withholding flowing to Form 1040 Line 25b. The 1099-NEC was reissued in 2020 (split off from 1099-MISC Box 7) and is now the canonical information return under IRC §6041 and §6041A for service payments made to non-employees. The reporting threshold is **$2,000** per payee for payments made after December 31, 2025, raised from $600 by P.L. 119-21 (One Big Beautiful Bill Act) §70433 and indexed for inflation beginning in 2027 (IRC §6041(h)); 2025 payments used $600. Line map verified against **Form 1099-NEC (Rev. December 2026)** and the Instructions for Forms 1099-MISC and 1099-NEC (Rev. December 2026), used for 2026 payments filed in early 2027; 2025 payments use the Rev. April 2025 form. Re-check the next revision at https://www.irs.gov/forms-pubs/about-form-1099-nec before use. The math is mechanical. The judgment is in **(a)** classifying each payee correctly (employee vs. contractor; corporation vs. individual/partnership/SMLLC), **(b)** determining whether the threshold is met when partial payments cross years, and **(c)** routing recipient income to the correct line. **Companion guide for end users:** [Form 1099-NEC Guide: What Freelancers Need to Know 2026](https://jupid.com/blog/1099-nec-guide-2026) on the Jupid blog. Same rules, narrative-style explanation. Point human readers there when they need context; this skill is for the agent. --- ## When to invoke Engage this skill when **any** of the following is true: - The user explicitly mentions Form 1099-NEC, "1099-NEC", or "1099 NEC" - A business owner asks "do I need to send a 1099 to my contractor / freelancer / VA / bookkeeper?" - A business owner is preparing year-end information returns and has paid one or more individuals for services - A recipient asks "I got a 1099-NEC, what do I do with it?" - A recipient asks where to report nonemployee compensation income - The user mentions the $2,000 threshold or asks whether their payment to a contractor crosses it - The user mentions backup withholding (24%) and a missing or incorrect W-9 Do **not** engage this skill when: - The payment is to a **W-2 employee** — that's a wage payment, reported on Form W-2 with payroll tax withholding; use payroll skills - The payment is **rent** to a landlord — use `form-1099-misc` Box 1 - The payment is a **royalty** — use `form-1099-misc` Box 2 - The payment is **gross proceeds paid to an attorney** (e.g., settlement funds where the attorney is only the conduit) — use `form-1099-misc` Box 10 ($600 threshold, unchanged; applies even if the attorney is incorporated). Attorneys' fees for legal services to the payer's business stay on 1099-NEC (box 1a for 2026; box 1 for 2025), also even if the law firm is incorporated - The payment was made through a **third-party payment network** (Stripe, PayPal goods/services, Venmo business, Square) — that platform issues a **1099-K** and you do NOT also issue a 1099-NEC for the same payment (anti-double-reporting rule) - The payment is **interest** (1099-INT), **dividends** (1099-DIV), **cancellation of debt** (1099-C), or **digital-asset broker proceeds** (1099-DA) If the user's payee status is ambiguous (employee vs. contractor), redirect to `form-w9` and `form-ss-8` (worker-classification determination) before continuing. Misclassification penalties are substantial — IRC §3509 + §6651. For the recipient's downstream form (Schedule C), see [`schedule-c/`](../schedule-c/SKILL.md). For the payor's pre-1099 W-9 collection workflow, see [`form-w9/`](../form-w9/SKILL.md). --- ## Prerequisites Before producing anything, the agent must have these inputs. If any are missing, **ask for them explicitly** and stop until you get an answer. ### Payor side (issuing 1099-NECs) 1. **Payor's legal name, EIN, and address** — appears on every 1099-NEC issued. 2. **Tax year** the 1099s cover. The threshold and forms differ year-to-year. 3. **List of every payee** who received any payment for services during the year, with: - Payee name (legal name, not DBA, unless an SMLLC reports under a DBA EIN) - Payee Tax ID (SSN, ITIN, or EIN) — collected via Form W-9 *before* paying - Payee mailing address - Total gross paid in the calendar year (cash + check + ACH + Zelle direct bank-to-bank — NOT third-party-network payments, those go on 1099-K issued by the platform) - Whether the payee is incorporated (C-corp or S-corp = generally exempt; LLC may or may not be — depends on tax election, see W-9 Line 3) - Whether backup withholding applies (24% if W-9 missing or TIN doesn't match) 4. **Filing channel** — IRIS (Information Returns Intake System, free; from filing season 2027 it is the only IRS e-file intake for information returns because FIRE shuts down at the end of 2026 — Pub. 1099 (2026), What's New), paper with Form 1096, or a third-party service (Track1099, Tax1099, QuickBooks). Required: the payor must file electronically if issuing 10+ information returns total in the year (aggregated across all information return types, W-2s included — T.D. 9972). 5. **State filing requirements** — many states receive data through the federal Combined Federal/State Filing Program (CF/SF), which IRIS supports, but some states require separate state filing. Confirm in the CF/SF Program section of Pub. 1099 (2026) and with the state's revenue department. ### Recipient side (received a 1099-NEC) 1. **Filer's legal name and SSN/ITIN** — for Schedule C header or 1040. 2. **Form copy** — Box 1 (gross nonemployee compensation), Box 4 (federal income tax withheld), Boxes 5-7 (state income / state tax / payer state ID). 3. **Underlying activity** — was this a trade or business (regular, continuous, profit-motive — Schedule C) or a one-off gig (Schedule 1 Line 8z, "Activity not for profit" or one-off "Other earned income")? 4. **The recipient's own records** — what services were performed, what was the total billed, and does it match Box 1? Discrepancies are the most common error mode. 5. **Any business expenses** related to earning the income — only relevant if Schedule C path. For a recipient who is also a sole proprietor / SMLLC, the income flows directly to Schedule C Line 1 along with other gross receipts. For a one-off recipient (e.g., paid honorarium for a single speaking engagement), the income flows to Schedule 1 Line 8z and is **not** subject to self-employment tax (because it's not a trade or business). If the recipient classification (business vs. one-off) is ambiguous, ask before routing. The most common mistake: a freelancer with one client who reports on Schedule 1 Line 8 instead of Schedule C, missing the SE tax obligation and the deduction opportunity. --- ## Workflow ### Payor side workflow #### Step 1 — Confirm the payee universe Pull every payment made for services during the calendar year. Exclude: - W-2 wages (those go on W-2) - Reimbursements substantiated under an accountable plan (not reportable) - Payments to corporations, except medical and health care payments (1099-MISC Box 6) and payments for legal services (attorneys' fees on 1099-NEC box 1a; gross proceeds on 1099-MISC Box 10), which are reportable even if the payee is incorporated - Payments made via third-party payment network (Stripe, PayPal goods/services, Square, Venmo business, Cash App for Business) — the platform issues 1099-K - Personal payments (not for the trade or business) Net list: every individual / partnership / SMLLC paid for services in the calendar year. #### Step 2 — Apply the threshold For tax year 2026, issue a 1099-NEC to any non-corporate payee paid **≥ $2,000** in aggregate for services during the calendar year (P.L. 119-21 §70433; Instructions for Forms 1099-MISC and 1099-NEC, Rev. December 2026). From 2027 the amount is inflation-adjusted in $100 steps (IRC §6041(h)); read the current figure at IRS.gov/InflationAdjustment. See [`references/threshold-rules.md`](./references/threshold-rules.md). For tax year 2025 and prior: the threshold is **$600**. If backup withholding was applied, issue a 1099-NEC regardless of amount (any amount of backup withholding requires the form). The same $2,000 line now governs when backup withholding is required on these payments (Pub. 1099 (2026), What's New; IRC §3406(b)(6)). #### Step 3 — Verify W-9 data for each payee crossing the threshold For each payee that crosses the threshold: - Confirm a current Form W-9 is on file - Confirm payee's TIN is present (SSN or EIN) - Confirm the legal-name / TIN combination matches IRS records (use the IRS TIN Matching service via e-Services) - If W-9 is missing: solicit (Form W-9 second-request letter); apply backup withholding (24%) on future payments until received - If the IRS sends a CP2100/CP2100A incorrect-TIN notice: promptly send the payee a "B" notice and request a certified W-9; backup withholding is required on payments made more than 30 business days after you received the IRS notice until a certified TIN arrives (Pub. 1099 (2026), part N; Pub. 1281) See [`references/backup-withholding.md`](./references/backup-withholding.md). #### Step 4 — Populate each box on Form 1099-NEC Per [`references/line-by-line.md`](./references/line-by-line.md): - **Payer** block (top-left): payer's name, address, phone - **Payer's TIN**: payer's EIN - **Recipient's TIN**: payee's SSN or EIN from W-9 - **Recipient's name and address**: from W-9 - **Box 1a** (Box 1 on the Rev. April 2025 form for 2025 payments): total gross paid for services during calendar year (do not net against expenses or refunds) - **Box 1b**: cash tips included in box 1a (new for 2026, P.L. 119-21 §70201) - **Box 1c**: Treasury Tipped Occupation Code(s) (TTOC), up to two - **Box 1d**: qualified overtime compensation included in box 1a (only the premium "half" of time-and-a-half; new for 2026, P.L. 119-21 §70202) - **Box 2**: payer made direct sales totaling ≥ $5,000 of consumer products to recipient for resale (checkbox; rare) - **Box 3**: excess golden parachute payments (rare) - **Box 4**: federal income tax withheld (backup withholding amount, if any) - **Boxes 5-7**: state-level reporting (state income tax withheld, state name + payer state ID, state income) #### Step 5 — Distribute copies Each 1099-NEC has multiple copies: - **Copy A** — to IRS (paper with Form 1096, or electronic via IRIS) - **Copy B** — to recipient (mail or e-deliver with consent) - **Copy C** — payer's records - **Copy 1** — to state tax department (if state requires) - **Copy 2** — to recipient for state filing **Recipient copy (Copy B): due January 31** following the tax year (postmarked or e-delivered); the next business day if January 31 is a weekend or legal holiday (2025 forms were due February 2, 2026; 2026 forms are due February 1, 2027). **IRS copy (Copy A): due January 31** (same as recipient copy — note 1099-NEC is special; it's earlier than 1099-MISC's IRS deadline; IRC §6071(c)). Paper or electronic — same date. If submitting **10 or more information returns total** across all types in the calendar year, electronic filing is **mandatory** (TFA 2019 authority in IRC §6011(e); T.D. 9972). #### Step 6 — File state copies If the state isn't on the IRS Combined Federal/State Filing program, file separately with the state. Refer to the state's department of revenue. Some require electronic filing through state portals (e.g., Pennsylvania myPATH). #### Step 7 — Hand off to filing.md For browser-driven filing through IRS IRIS, see [`filing.md`](./filing.md). ### Recipient side workflow #### Step R1 — Classify the activity Was the payment from a trade or business activity (regular, continuous, profit-motive)? - **Yes** → Schedule C path - **No** (one-off honorarium, occasional gig) → Schedule 1 Line 8z path If ambiguous, ask the user. The IRS factors for "trade or business" are at IRC §162 and Reg. §1.183-2(b) (nine-factor test). #### Step R2 — Schedule C path The Box 1 amount becomes part of the user's gross receipts on Schedule C Line 1 (alongside other 1099s, 1099-Ks, cash, and other income). Do NOT line-item each 1099-NEC separately on the form — Line 1 is the aggregate. The recipient's own records should match or exceed each Box 1 amount. If records are less than Box 1, investigate (the payor may have included payments that didn't reach the recipient, or there's a year-end timing difference). Then run the [`schedule-c/`](../schedule-c/SKILL.md) skill for the rest of the return. #### Step R3 — Schedule 1 path (one-off gig) If the activity isn't a trade or business: - Box 1 amount → Schedule 1 Line 8 (specific 8z if "Other earned income" applies) - No Schedule SE (not subject to SE tax — IRC §1402(a)) - No Schedule C - Expenses generally **not deductible** (miscellaneous itemized deductions are disallowed by IRC §67; P.L. 119-21 §70110 made the disallowance permanent) #### Step R4 — Box 4 federal withholding If Box 4 > 0 (backup withholding was applied): - The amount goes on Form 1040 Line 25b (Form(s) 1099) — 2025 Form 1040 - The recipient gets credit for the withheld amount against their total federal income tax liability #### Step R5 — Box 5-7 state items State income on Box 7 ties to the state return. Box 5 (state tax withheld) gets credited on the state return. Most state returns mirror the federal flow. #### Step R6 — Validate and produce deliverable See **Validation** below. --- ## Line-by-line guidance For the full reference, load [`references/line-by-line.md`](./references/line-by-line.md). High-level rules below. ### Header (payer/recipient blocks) - **Payer's name, address, phone**: top-left. Must match payer's IRS records. - **Payer's TIN**: EIN preferred; SSN if a sole proprietor with no EIN issuing 1099s (rare). - **Recipient's TIN**: from W-9. Truncate on Copy B (recipient copy) per Reg. §301.6109-4 — show only last 4 digits — but full TIN on Copy A (IRS copy). - **Recipient's name and address**: legal name from W-9 Line 1; DBA (if any) from W-9 Line 2 below the legal name. - **Account number**: optional internal payer reference; required if filing multiple 1099s for the same recipient. ### Box-by-box (the core) | Box | Field | What goes here | What does NOT go here | |-----|-------|----------------|------------------------| | 1a (1 on Rev. April 2025) | Nonemployee compensation | Total gross paid for services in the calendar year, incl. attorneys' fees for legal services | Reimbursements under an accountable plan; payments via card or 1099-K platform; goods (not services) | | 1b | Cash tips | Cash tips included in 1a (2026 form) | | | 1c | TTOC | Treasury Tipped Occupation Code(s), up to two (2026 form) | | | 1d | Overtime compensation | Qualified overtime premium included in 1a (2026 form) | | | 2 | Direct sales of consumer products ≥$5,000 | Check box if applicable (rare) | Dollar amount | | 3 | Excess golden parachute payments | Amount over the base amount (Reg. §1.280G-1) | | | 4 | Federal income tax withheld | Backup withholding amount (24%), if any | Voluntary withholding (no such thing on 1099-NEC) | | 5 | State tax withheld | State income tax withheld, if any | Federal withholding (Box 4) | | 6 | State / Payer's state no. | State 2-letter abbreviation + payer's state ID number | | | 7 | State income | Amount of Box 1 attributable to that state | | ### Handling multi-state payees If the payer paid the recipient who works across multiple states, complete one 1099-NEC with multi-row state breakdown in Boxes 5-7 (the form supports two state rows; for more, the payer attaches a continuation). --- ## Validation Before declaring the form ready, run these checks. Surface anything that fails — don't silently fix. ### Math checks (payor side) - [ ] Sum of all 1099-NECs Box 1 issued = total payments to payees ≥ threshold (with no backup withholding) + total payments to payees with any backup withholding - [ ] Sum of all 1099-NECs Box 4 = total backup withholding remitted to IRS via Form 945 - [ ] Number of 1099-NECs filed reported on Form 1096 (paper) matches actual count ### Sanity checks (payor side) - [ ] Any payee paid ≥ $2,000 (2026) without a W-9 on file → triggers backup withholding obligation - [ ] Any payee with an EIN → confirm not a corporation (corporations are exempt for services unless legal services or medical payments); use [`references/payee-classification.md`](./references/payee-classification.md) - [ ] Any payee paid by credit/debit card or via Stripe / PayPal / Venmo business / Square → exclude (reportable on Form 1099-K by the payment settlement entity, not on 1099-NEC) - [ ] Any reimbursement included in Box 1 → confirm the reimbursement is NOT under an accountable plan (if accountable, exclude) - [ ] Total information returns (1099-NEC + 1099-MISC + 1099-K + 1099-INT + 1099-DIV + W-2) ≥ 10 → e-filing mandatory ### Math checks (recipient side) - [ ] Schedule C Line 1 ≥ sum of all 1099s received (NEC + K + MISC + others reporting receipts) - [ ] If Box 4 > 0, Form 1040 Line 25b reflects it - [ ] Schedule 1 Line 8 (one-off path) = Box 1 amount ### Sanity checks (recipient side) - [ ] Recipient's records match Box 1 within ~$200 → if not, investigate timing or missing income - [ ] Recipient's classification (business vs. one-off) confirmed → SE tax treatment depends on it - [ ] No double-reporting: if same income also on a 1099-K (rare but happens with Stripe + direct check from same client), only count once --- ## Output format ### Payor-side deliverable: 1099-NEC issuance plan ```markdown # Form 1099-NEC — Issuance Plan for tax year YYYY Payer: (EIN: XX-XXXXXXX) ## Payees requiring 1099-NEC | Payee Name | TIN (last 4) | Address | Box 1 Total | Box 4 Withhold | State Boxes | |------------|--------------|---------|-------------|----------------|-------------| | ... | XXX-XX-1234 | ... | $X,XXX | $0 | ... | Total 1099-NECs to issue: N Total Box 1: $X,XXX Total Box 4 (to remit on Form 945): $X,XXX ## Excluded (with reason) | Payee Name | Reason for exclusion | |------------|----------------------| | Acme Inc. | C-corp (services, non-medical, non-legal) — exempt | | ... | Paid via Stripe — covered by 1099-K | ## Filing checklist - [ ] Recipient copies (Copy B) postmarked or e-delivered by January 31 - [ ] IRS copies (Copy A) filed by January 31 (electronic via IRIS or paper with Form 1096) - [ ] State copies filed (if state not in CF/SF program) - [ ] Form 945 filed if any backup withholding remitted - [ ] Records retained for 4 years (IRC §6501(a) statute of limitations + buffer) ## Sources cited - IRS Form 1099-NEC, Rev. - IRS Instructions for Forms 1099-MISC and 1099-NEC, Rev. - IRC §6041, §6041A, §3406 (backup withholding) - P.L. 119-21 §70433 (threshold $2,000 for payments after 2025;

It is not tax advice. It does not establish a CPA-client relationship. The agent invoking this skill should remind the user, when producing a draft, that the output is a starting point and that complex situations (worker misclassification disputes, multi-state allocation, payments to attorneys with split plaintiff/attorney portions) warrant a licensed tax professional's review.
