TaxBandits 1099 API — Use Cases

For software platforms that process payments to contractors, vendors, or sellers, 1099 filing is not a once-a-year task — it is an ongoing data integrity challenge. Payment records accumulate across thousands of recipients, thresholds differ by form type, state filing rules vary, and the January 31 deadline leaves almost no margin for error.

The TaxBandits API is built to fit into different platform workflows, whether your system manages the full recipient lifecycle, tracks payments throughout the year, or simply needs to file completed 1099 data at year-end.

You can choose the integration approach that matches your use case:

• Automate end-to-end 1099 cycle: Collect W-9/W-8 information, validate TINs, record transactions, and generate 1099s from the same workflow
• Record transactions & generate 1099s: Record payments as transactions throughout the year and generate forms automatically at year-end
• Create 1099 forms directly: Create and file 1099 forms directly using annual payment totals already calculated in your platform

This flexibility allows your platform to automate 1099 compliance without changing how your existing payment, payroll, accounting, or vendor management system operates.

Gig & Freelance Marketplaces

Gig and freelance platforms can have thousands of contractors completing paid work every day. Payment volumes are unpredictable, contractor counts fluctuate seasonally, and annual totals cannot be known until year-end. Waiting until December to collect and reconcile payment data is a compliance risk—and a manual nightmare.

PAIN POINT	TAXBANDITS SOLUTION
Tracking payment totals for thousands of      contractors across the full year	Each payment is posted as a transaction in real time        — TaxBandits maintains the running ledger
Knowing which contractors crossed the $600 NEC      threshold	Threshold enforcement is automatic — recipients        below the limit are excluded from filing
Year-end data reconciliation consumes weeks of      engineering time	GenerateFromTxns produces all 1099-NEC records        from the transaction ledger in seconds
Contractor TIN errors causing IRS 'Accepted with      Errors' returns	TIN Matching validates every contractor's name and       TIN before a form is filed
Getting corrected forms to contractors quickly after      errors	Corrections are filed via API and delivered digitally        through Online Access the same day

How it works

1. Record each payment as a transaction

   Every time a contractor completes a paid job, post it as a transaction with the payer, recipient, amount, and payment type. TaxBandits maintains a running ledger for each contractor throughout the year.

2. Generate 1099-NEC records at year-end

   In January, trigger generation for all contractors. The API sums transactions per contractor, applies the IRS reporting threshold, and produces 1099-NEC records automatically. Contractors below the threshold are excluded.

3. Review and approve

   Inspect the generated records for accuracy. Approve the batch to make it eligible for transmission.

4. Transmit to the IRS

   File federally with a single Transmit call. Include state filing in the same request if needed.

5. Distribute recipient copies

   Enable Online Access so contractors receive a secure email link to download their 1099-NEC. No printing or mailing required.

Payroll & HR Software

Payroll software holds the most complete view of what was paid to whom and when. But turning that data into IRS-filed, state-compliant 1099 returns across hundreds of client businesses—each with different states, different contractor lists, and different form types—is a significant build if done in-house. The TaxBandits API makes it a configuration problem, not an engineering one.

PAIN POINT	TAXBANDITS SOLUTION
Filing 1099-NEC and 1099-MISC for different types of      payees from the same system	Both form types are supported in a single API —        specify the form type per batch
Managing multi-state filing for employers operating      across multiple states	Set IsFederalFiling and IsStateFiling to TRUE — both        submitted in one Transmit call
State reconciliation forms required on top of 1099s in      some states	Include StateReconData in the Create request —       TaxBandits handles the recon form automatically
Printing and mailing recipient copies across       thousands of contractors at year-end	IsPostal TRUE enables managed USPS mailing with       address validation — zero fulfillment overhead
IRS rejection after transmission requiring re-filing	Rejection payloads include specific error codes. Fix a       corrected return via the corrections endpoint.

How it works

1. Prepare consolidated payment data

   Payroll platforms already hold annual totals per contractor and employee. Export the data in the format your integration expects — no additional aggregation needed.

2. Create 1099 records in batch

   Submit up to 250 records per Create request. Specify the form type per batch (1099-NEC for contractors, 1099-MISC for other payees). Include IsFederalFiling and IsStateFiling flags and attach StateReconData for states that require a reconciliation form.

3. Validate before transmitting

   Call Validate to audit all records against IRS business rules before submission. Resolve any errors that surface.

4. Transmit to IRS and states

   A single Transmit call files federally and with all applicable state agencies simultaneously.

5. Manage recipient copies

   Enable IsPostal to have TaxBandits print and mail recipient copies via USPS with address validation. Enable IsOnlineAccess to deliver digitally, or both.

6. Monitor status and handle rejections

   Use webhooks or the Status endpoint to track acceptance. If the IRS rejects a return, the payload includes specific error codes — file a corrected return via the corrections endpoint.

Affiliate & Creator Networks

Affiliate and creator platforms make frequent, variable payments to large pools of payees—some earning across multiple campaigns or revenue streams. Commissions are not fixed amounts, payee rosters change constantly, and the same payee might receive both commission payments (1099-NEC) and prize awards (1099-MISC). Sorting this out manually at year-end is error-prone at scale.

PAIN POINT	TAXBANDITS SOLUTION
Publishers earning across multiple campaigns —       totals scattered across systems	Transaction recording aggregates all payments per        payee automatically throughout the year
Commission vs prize payments requiring different       1099 form types	Post commissions as 1099-NEC transactions and        prizes as 1099-MISC—both supported in the        same API
Hundreds of payees who just missed the $600      threshold clogging filing queues	Threshold enforcement is built in — sub-threshold        payees are automatically excluded
W-9 not collected at onboarding leading to TIN      mismatch errors at filing	Collect W-9 via the TaxBandits W-9 API at       onboarding and validate TIN before the first       commission is paid
Sending corrected 1099s to international publishers       with address complications	Online Access delivers corrected forms digitally—no        postal address required

How it works

1. Collect W-9 at onboarding

   When a publisher or affiliate signs up, request their W-9 via the TaxBandits W-9 API. The form can be embedded directly in your onboarding flow or portal.

2. Validate TINs before the first payment

   Run TIN Matching against the IRS database to confirm the publisher's name and TIN combination is correct. Flag mismatches before any commission is paid.

3. Record each payment as a transaction

   Post every commission, bonus, or revenue share payment as a transaction tied to the correct payer and recipient. Specify the form type — 1099-NEC for commissions, 1099-MISC for prizes and awards.

4. Generate 1099s at year-end

   Trigger generation for each form type. The API aggregates all transactions per publisher, applies the threshold, and produces records for qualifying recipients only.

5. Transmit and distribute

   File with the IRS and deliver recipient copies via Online Access. Publishers receive a secure link by email — no postal address required, which matters for international publishers.

Property Management Software

Property management software sits between landlords, tenants, and vendors—handling rent collection, maintenance payments, and owner distributions. Each of these payment flows has different 1099 obligations: rent distributions to property owners trigger 1099-MISC, and payments to contractors and vendors for services require 1099-NEC. Getting this right across multiple properties, multiple states, and multiple owner entities is a recurring compliance challenge.

PAIN POINT	TAXBANDITS SOLUTION
Monthly owner distributions need 1099-MISC (Box 1,        Rents) at year-end..	Post each monthly distribution as a 1099-MISC        transaction—year-end totals are already aggregated
Vendor payments for maintenance and services need        a 1099-NEC	Post service payments as 1099-NEC transactions—        the correct form is generated automatically
State income tax withheld from owner distributions        varies by state and owner	State withholding details captured at the transaction        level flow directly into year-end records
Many owners are LLCs or S-Corps that don't require a       1099	Entity type is captured in the W-9—TaxBandits        automatically excludes exempt recipient types
Owners in multiple states requiring multi-state filing	Multi-state filing is handled in a single Create +        Transmit request with state data per owner

How it works

1. Post each owner's distribution as a transaction

   Every month, when rent proceeds are distributed to property owners, post the payment as a 1099-MISC transaction.

2. Post vendor and contractor payments as transactions

   When paying a plumber, landscaper, or any service provider, post that payment as a 1099-NEC transaction. The API tracks both form types simultaneously, per recipient.

3. Handle exempt entities automatically

   Entity type captured via W-9 (LLC, S-Corp, C-Corp) is used to exclude recipients who don't require a 1099. No manual filtering needed.

4. Generate 1099-MISC and 1099-NEC records at year-end

   Trigger generation separately for each form type. Totals per owner and per vendor are already correctly aggregated.

5. File and distribute

   Transmit with state filing included where required. Enable postal mailing for owners who prefer a physical copy, or Online Access for digital delivery.

Payment & Marketplace Platforms

Payment processors, online marketplaces, and B2B disbursement platforms face a specific compliance challenge: they move money on behalf of other businesses, which means they carry the 1099-K reporting obligation for payment network transactions. At scale, this means managing reporting for thousands of merchants across multiple payment channels—with a hard threshold, a hard deadline, and state-level variation on top.

PAIN POINT	TAXBANDITS SOLUTION
1099-K required for merchants exceeding $20,000       and 200 transactions (TPSO threshold)	1099-K is fully supported—the API handles threshold        tracking and form generation per merchant
Payment card transactions require a 1099-K with no      dollar threshold	Card vs TPSO logic is handled at the form level—no        threshold applies to card transactions
Multiple business clients, each with their own       merchant list and payer identifier	Each disbursement is posted with the correct        BusinessId—generate separate batches per client at        year-end
State 1099-K thresholds differ from federal; some      states require forms at $600	State filing is independent from federal—set        IsStateFiling to TRUE with state-specific data per        merchant
Merchants disputing 1099-K amounts requiring       corrections after filing	File a 1099-K correction via Form1099KCorrection

How it works

1. Post each merchant disbursement as a transaction

   Every payment processed on behalf of a merchant is posted with the correct BusinessId (payer identity) and recipient. Card transactions and TPSO transactions are tracked separately at the posting level.

2. Track thresholds per merchant

   The API accumulates payment totals and transaction counts per merchant. For TPSOs, generation is triggered only for merchants exceeding $20,000 and 200 transactions. For payment card records, no threshold applies — all merchants are included.

3. Generate 1099-K records per payer

   At year-end, trigger generation per business client. Because payer identity is captured at the transaction level, separate 1099-K batches are produced per client — each with their own merchant list.

4. File federally and with states

   Set IsStateFiling to TRUE for merchants in states with lower reporting thresholds (some states require 1099-K at $600). Federal and state filings are submitted in a single Transmit call.

5. Handle merchant corrections

   If a merchant disputes an amount or a TIN was incorrect, file a corrected 1099-K via the corrections endpoint. TaxBandits re-transmits to the IRS and, if Online Access is enabled, the merchant receives the updated form automatically.
