The IRS does not automatically send every 1099 to every state. The Combined Federal/State Filing Program forwards eligible returns only to states that participate, and even then, state agencies set their own rules on top of it. Before you rely on forwarding, confirm each state’s requirement directly, because several states mandate their own direct filing regardless of what the IRS transmits.
TL;DR:
- Many states require direct filing of 1099s regardless of the IRS forwarding through CF/SF, especially if they have lower thresholds or specific mandates.
- Rhode Island’s 2026 rules mandate 1099 filings for payments over $100, which is significantly below federal reporting thresholds.
- Filers should verify each state’s current filing requirements and thresholds annually, as rules change more frequently at the state level than federally.
- Using the IRS IRIS portal or high-volume A2A systems depends on filer size and participation in CF/SF, with state-specific registration often necessary.
- State filing platforms vary in acceptance formats and procedures, requiring careful preparation, testing, and correct mapping of payee and state codes.
The IRS runs two main filing channels for information returns, and a separate forwarding program that connects to states. Confusing these three creates most of the compliance gaps filers run into.
The IRIS Taxpayer Portal lets filers key in data manually or upload a CSV file at no cost. Starting in January 2026, the CSV upload limit increased to 250 forms per file, which helps small and mid-size filers avoid splitting batches. IRIS Application-to-Application, known as A2A, is built for high-volume filers who submit bulk XML data. It requires a Transmitter Control Code and a testing period before live submissions go through.
Then there’s the Combined Federal/State Filing Program, which forwards eligible returns to states that participate. The IRS acts only as a forwarding agent here; for more on these obligations, see FATCA Reporting Obligations for U.S. Taxpayers in Bulgaria. It does not decide whether a state accepts the data as sufficient, and it does not exempt you from a state’s own filing mandate.
TaxFormHero is an IRS-authorized e-filing platform, so you can e-file Form 1099-NEC online without paper or a subscription.
States don’t all follow the CF/SF program the same way. Some accept forwarded data as complete. Others require direct filing regardless, and some set thresholds that trigger reporting even when the IRS wouldn’t require it federally.
Common triggers for direct state filing include a state-specific e-filing mandate, a dollar threshold lower than the federal minimum, or state tax withholding reported on the 1099. Massachusetts requires many filers to submit directly through its MassTaxConnect portal, separate from any federal forwarding. Rhode Island went further in 2026.
Rhode Island’s 2026 advisory requires informational 1099 filings for payments over $100 for certain forms, a threshold far below what most filers expect from federal rules.
State rules shift more often than federal ones, so treat any threshold you’ve memorized as temporary and check the state’s current guidance before you file.
Choosing the right channel depends on your volume, your systems, and whether the state you’re filing for participates in CF/SF at all.
Pro Tip: Run a small test file before switching systems. A single bad state code in a large batch can force you to correct hundreds of records instead of one.
Confirm every item here before you submit, especially if you’re filing across multiple states.
Small business owners filing across three or four states often lose more time to mismatched formats than to the filing itself. A short internal checklist like this one, reviewed before you file 1099-NEC forms each season, catches most of the recurring errors.
Even filers who’ve handled 1099s for years assume CF/SF covers more than it does.
Pro Tip: States can request CF/SF participation, but changes can take up to a year to appear in actual distributions, according to the IRS CF/SF coordinator FAQs. If a state recently joined, don’t assume this year’s filing is already covered.

CF/SF gets marketed, informally, as a one-stop filing solution. It isn’t one. It’s a forwarding mechanism with a state-by-state opt-in list, and the states that don’t participate, or that layer their own thresholds on top, are exactly the ones that catch filers off guard.
The bigger problem isn’t ignorance of CF/SF. It’s overconfidence in it. Filers check the box, assume the IRS handled the rest, and move on. The states with the strictest rules, like Rhode Island’s low-dollar threshold, are rarely the ones filers think to double-check, because the assumption is that a small 1099 amount won’t trigger anything. Read state guidance for the specific states where your payees live, every filing season, rather than relying on last year’s notes.

There are IRS-authorized platforms built for the workflow this checklist describes that support 1099-NEC, 1099-MISC, W-2, ACA forms, and other IRS information returns, with built-in TIN matching that catches mismatched taxpayer ID numbers before they cause a rejected filing.

State filing is available as an add-on for 35+ states, which removes the step of registering separately with each state portal for filers who qualify. Pricing runs pay-per-form with no subscription or signup fee: 1099-NEC filing starts at $1.99 per form, and state filing adds $0.99 per form through the pricing page. The platform holds a SOC 2 Type I attestation.
If you’re running through the checklist above and want fewer manual steps, file your 1099-NEC forms online and compare the state filing add-on against your current state-by-state process.

Check the IRIS 101 guide and Topic No. 804 for federal rules, and your target state’s tax agency for current thresholds, since state guidance changes independently of federal updates.
Only if the IRS forwards it through the Combined Federal/State Filing Program and your state participates in that program. Even then, some states still require a separate direct filing, so check your specific state’s rule rather than assuming forwarding covers it.
The IRIS Taxpayer Portal raised its CSV upload limit to 250 forms per file starting January 2026, which affects how filers batch their submissions. Some states, like Rhode Island, also updated their own thresholds in 2026, so check both federal and state guidance for your filing year.
Federal rules generally set a threshold for many 1099 forms, but some states set their own, lower thresholds. Rhode Island’s 2026 advisory requires filing for certain payments over just $100, so a payment under that federal threshold can still trigger a state filing obligation.
Check whether your state participates in the Combined Federal/State Filing Program and review that state’s own tax agency guidance, since participation doesn’t always eliminate a separate state filing requirement. States like Massachusetts require direct portal filing for many filers regardless of federal forwarding.
