Filing 1099 forms correctly is one of the most deadline-sensitive compliance tasks a business owner or bookkeeper faces each year. Miss a deadline, use the wrong form type, or submit an incorrect TIN, and you’re looking at penalties that escalate automatically the longer the issue goes unresolved.
Online filing becomes manageable once you know the steps. This guide covers the full process for the 2026 tax year, filed in early 2027, including two rule changes businesses need to be aware of.
First, if you file 10 or more total information returns in a calendar year (combined across all types, including W-2s, 1099s, and 1098s), you are required to eFile with the IRS. Paper filing is only available below this threshold, which went into effect for the 2023 tax year and beyond. This is still something that small businesses overlook each tax season.
Second, under the One Big Beautiful Bill Act signed on July 4, 2025, the reporting threshold for several popular 1099 forms, including Form 1099-NEC, 1099-MISC, and 1099-K, has changed. These unprecedented threshold updates will impact many filers, with significant increases for forms like the 1099-K, which will see its threshold rise from $600 (with no transaction limit) back to the original $20,000 / 200 transaction limit.
Who Is Required to File a 1099 and Which Threshold Applies
Any business, sole proprietor, partnership, nonprofit, or corporation that makes qualifying payments to non-employees, vendors, or service providers must file a 1099 when payments meet or exceed the reporting threshold for that form type.
You do not file a 1099 for payments to W-2 employees, payments to C-corporations or S-corporations (with limited exceptions such as medical or legal payments), or payments processed via credit card or third-party payment networks, as those are reported on Form 1099-K instead.
| Form | Payment Type | 2027 Threshold |
| 1099-NEC | Non-employee compensation (contractors, freelancers) | $2,000 |
| 1099-MISC | Rent, attorney fees, prizes, medical payments (most boxes)* | Generally $600 (varies by box; some payments may be subject to updated thresholds) |
| 1099-INT | Interest paid (trade/business) | $10 / $600 |
| 1099-DIV | Dividends and distributions | $10 |
| 1099-R | Retirement distributions, pensions, annuities | $10 |
| 1099-K | Third-party payment network transactions | $20,000 / 200 transactions |
*Thresholds for specific 1099-MISC boxes (such as royalties or direct sales) follow separate IRS rules and are not uniform across all payments.
Step 1: Gather What You Need Before You File
Rushing into the filing portal with incomplete data is the most common cause of errors, rejections, and penalty notices. Work through this checklist before you open any filing system.
- Collect a completed W-9 form from every payee. The form provides the payee’s legal name, address, TIN (Social Security Number or EIN), and entity type. Do not proceed without one. If a vendor refuses to provide a TIN, you are required to begin backup withholding at 24% immediately and document the refusal.
- Total all payments per vendor for the calendar year. Count every payment made to that vendor across the year. Partial-year or sporadic payments still count toward the annual threshold.
- Verify every TIN before filing. A mismatched TIN is the single most common trigger for IRS CP2100 notices and potential penalties. Run each TIN through IRS TIN Matching or a provider that includes real-time verification before entering data.
- Know your state filing requirements. Not all states participate in the Combined Federal/State Filing program, so you may still need to file directly with certain states depending on where your payees are located.
Step 2: Choose the Right 1099 Form Type
The form type is determined by what kind of payment was made, not the amount. Filing the wrong form is a filing error and may require a corrected return.
Use 1099-NEC for payments to independent contractors and freelancers for services. Use 1099-MISC for rent, attorney fees, prizes, crop insurance proceeds, and certain medical payments. If you paid a contractor for services and also reimbursed them for expenses, those are treated separately. Service payments may be 1099-NEC reportable; reimbursements generally are not.
If you are unsure which form applies, refer to the IRS Instructions for Forms 1099-MISC and 1099-NEC or the IRS General Instructions for Certain Information Returns.
Step 3: Choose Your eFiling Method
The IRS is transitioning away from the FIRE system and moving filers to the IRIS platform. For the 2027 filing season, plan to file through IRIS or a third-party provider rather than relying on FIRE.
You have two main eFiling paths:
IRS IRIS Taxpayer Portal: The IRIS portal allows online eFiling of 1099 series forms. It is best suited for businesses filing fewer than 10 returns. Limitations include manual data entry only (CSV upload is available for smaller volumes), no built-in state filing support, and no print-and-mail service for recipient copies.
In addition to these constraints, businesses filing through IRIS must also apply for a new Transmitter Control Code (TCC) through the IRS prior to filing.
Third-Party eFiling Provider Platforms like eFileMyForms offer bulk CSV upload, real-time TIN verification, automated recipient copy delivery (print/mail or secure e-delivery), state filing support, and audit-ready records, with pay-as-you-go pricing and no subscription required.
Here’s a closer look:
| Feature | IRIS Portal | eFileMyForms |
| Bulk CSV upload | Limited—IRIS requires A2A API when filing over 200 forms | Yes |
| TIN verification | No | Yes |
| Recipient copy delivery | No | Yes (print) |
| State filing support | Limited via Combined Federal State Filing Program | Yes |
| Best for | Under 10 returns | 10+ returns or multi-state |
| TCC required | No | Yes |
If you file more than 10 returns, need CSV upload, require recipient mailing, or have state filing obligations, a third-party provider is the more practical choice.
Step 4: Enter, Validate, and Submit
The steps don’t change much, whether you’re using IRIS or a third-party provider:
- Enter or upload payee data: Include name, address, TIN, payment amounts by box, form type, and tax year
- Run validation checks: Most platforms flag missing TINs, formatting errors, zero-amount entries, and duplicate submissions before filing
- Review the filing summary: Confirm total form count, dollar amounts, form types, and any state filing selections
- Submit to the IRS: Your provider transmits the forms and issues a confirmation. Keep this as your filing record
- Track acceptance and fix issues: Most platforms show IRS acceptance within 24 to 48 hours. If anything is rejected, correct and resubmit promptly
Step 5: Deliver Copies to Recipients
Filing with the IRS is only half of your obligation. You must also furnish a copy to each payee by the recipient deadline, either by paper or electronic delivery.
Paper copies must be postmarked by the recipient deadline.
2026 Tax Year Filing Deadlines and Penalties
| Form | Recipient Copy Due | IRS eFile Due |
| 1099-NEC | January 31, 2027 (Likely February 1, 2027 since January 31 is a Sunday) | January 31, 2027 (adjusted if weekend rule applies) |
| 1099-MISC (Boxes 8 or 10) | February 15, 2027 | March 31, 2027 |
| 1099-MISC (all other boxes) | January 31, 2027 (adjusted if weekend rule applies) | March 31, 2027 |
| 1099-INT | January 31, 2027 (adjusted if weekend rule applies) | March 31, 2027 |
| 1099-DIV | January 31, 2027 (adjusted if weekend rule applies) | March 31, 2027 |
| 1099-R | January 31, 2027 (adjusted if weekend rule applies) | March 31, 2027 |
Note: If a filing deadline falls on a weekend or federal holiday, the IRS moves it to the next business day.
Penalties for missing the IRS eFile deadline escalate in tiers. Forms corrected within 30 days incur a $60 fee per form. Forms corrected between 31 days and August 1 incur a $130 fee per form. Forms filed after August 1 or never filed incur a $340-per-form fee. Intentional disregard carries a penalty of $680 per form with no cap.
Start Filing Before the Deadline Catches Up With You
1099 filing for the 2026 tax year involves more moving parts than previous years: new 1099 reporting threshold, mandatory eFiling for 10 or more returns, and the full transition from FIRE to IRIS. The businesses that get through it without penalties are the ones that start early.
Begin collecting W-9s in Q4, verify TINs before January, and choose a filing method that handles IRIS submissions, recipient copy delivery, and state filing without requiring you to manage the technical details yourself.
eFileMyForms, powered by Sovos, the largest private filer of information returns, lets you upload your data, run validation checks, send recipient copies, and submit forms to the IRS from one place without needing a subscription.

FAQs
Do I need to file a 1099 for every contractor I paid in 2026?
Only if payments meet the applicable threshold. For 2026 payments, the 1099-NEC threshold is expected to be $2,000, while most 1099-MISC thresholds remain at $600 unless specified otherwise.
What if a contractor will not give me their TIN?
If a payee refuses to provide a Taxpayer Identification Number, you are required to begin backup withholding immediately at a rate of 24% and document the refusal. You should still file the 1099 for any reportable payments made, using the information you have available.
What happens if I miss the filing deadline?
Penalties start at $60 per form if you correct within 30 days of the deadline and increase the longer the issue remains unresolved. Filing even a few weeks late is significantly cheaper than waiting until after August 1 or not filing at all. Late filing is always better than non-filing.
Can I still use the IRS FIRE system to file my 2027 tax year returns?
The IRS is phasing out the FIRE system and transitioning to IRIS for information return filing. For the 2027 filing season, most filers should plan to use IRIS or a third-party eFile provider instead of FIRE.
Do I need to file with my state as well as the IRS?
It depends. Some states participate in the IRS Combined Federal/State Filing program, which allows certain returns to be transmitted to participating states through IRIS. Others require direct state filing. Check your state’s requirements before assuming your federal filing covers both obligations.
