When are 1099-NEC and W-2 due for 2026?

For 2025 forms filed in 2026, 1099-NEC and W-2 Copy A to SSA/IRS are due February 2, 2026 (Jan 31 on weekend rule). 1099-MISC is March 2 e-file (March 31 in some references) — confirm current-year IRS calendar and state rules.

What is the e-file threshold?

10 returns aggregate across most information returns — effectively all employers must e-file. Confirm FIRE and SSA BSO requirements and TCC.

What are penalties for late 1099/W-2?

Tiered per-return penalties rising with lateness, plus intentional-disregard penalty per return with no cap, plus state penalties and interest on withholding.

How do you correct errors?

File corrected 1099 with CORRECTED box and 941-X / W-2c as needed, reconcile to GL, and retain reason memo. Fix the master data to prevent repeats.

1099 and W-2 Filing Deadlines 2026: Calendar, Penalties, and Correction Workflow

BATO Editorial Team October 01, 2026 3 min read

Calendar (Confirm Current IRS Publication)

Form	Federal due (2025 forms filed 2026)	Notes
W-2 Copy A to SSA	Feb 2, 2026	BSO/W-2c for corrections
1099-NEC	Feb 2, 2026	Independent contractor comp
1099-MISC	Mar 2, 2026 e-file	Rents, other income
1099-K	Mar 31 / state varies	Confirm threshold + state rules
State 1099/W-2	Jan 31–Mar 31 varies	Many states require direct filing

Dates shift with weekends and IRS updates. Confirm Publication 1220 and SSA specs before filing week.

Pair with 1099 vs W-2, Payroll, Year-End Close, and Year-End Tax Planning.

60-Day Prep Plan

Nov: scrub W-9s, TIN-match, verify addresses, lock vendor 1099 flags — see Bookkeeping. Dec: freeze AP cut-off, true-up bonuses, reconcile payroll to GL — see Multi-State. Jan: e-file, furnish recipient copies, reconcile filings to GL (zero plugs), file state copies.

Enforce roles per QuickBooks vs Xero and retain per Record Retention.

Penalty Tiers (Framework)

Filed ≤30 days late: lower per-return amount.
Filed after 30 days but by Aug 1: mid-tier.
Filed after Aug 1 or not filed: high-tier.
Intentional disregard: flat high amount per return, no cap.

Add state penalties and interest. Small counts still hurt — prevention is cheaper than correction.

Correction Workflow

Identify scope: returns, amounts, TINs.
File corrected federal + state promptly; issue W-2c/1099 corrected.
Amend payroll returns (941-X) if withholding affected.
Fix vendor master and payroll codes; memo root cause for Audit Procedures.

Worked Example: 40 Contractors, 3 Missing W-9s, 1 Wrong Box

December scrub finds: 38 valid W-9s on file, 2 missing, 1 LLC taxed as S-corp incorrectly flagged for 1099-NEC, and $18,000 in rent mis-coded to contractor expense (belongs on 1099-MISC, not NEC). Fixes before filing:

Issue	Fix	Penalty avoided
2 missing W-9s	Backup withholding notice + TIN solicitation log (documents reasonable cause)	$60–$310 per return tier
S-corp LLC flagged	Remove from NEC file; confirm via W-9 entity type	False filing + correction cycle
$18k rent on NEC file	Move to MISC, Box 1	Mismatched-form notice and CP2100 cycle

The TIN solicitation log is the unsung hero: first notice + second notice documented means missing-TIN penalties drop to reasonable-cause relief instead of intentional-disregard territory. Start it in November, not January 30th.

1099-K and State Threshold Chaos (2026 Reality)

Federal 1099-K thresholds moved repeatedly ($20k/200 → $5k → $2k proposals); states never waited. Massachusetts, Vermont, Virginia, and others enforce $600 state thresholds with direct filing — meaning you can owe zero federal K forms and dozens of state ones. Process:

Pull payment-settlement reports by state (Stripe/PayPal state breakdowns exist — use them).
Track monthly against each state’s threshold, not just federal — the same nexus-tracker discipline as SALT and SaaS Nexus.
File state copies directly where required (many states don’t accept FIRE-only; they want portal filing).

Calendar state 1099-K deadlines separately from federal — they cluster in the same Jan 31–Mar 31 window when the team is already at capacity. Assign the state matrix to one owner in the Year-End Close calendar.

TIN Matching That Actually Works

IRS TIN Matching (real-time or bulk) beats eyeballing W-9s: submit name/TIN pairs in November, fix mismatches with vendors while there’s time, and retain the match confirmations. Common failures: DBA vs legal name on line 1 (match line 1 exactly), hyphenated names truncated by AP entry, and single-member LLCs showing the owner’s SSN under the entity EIN. Each corrected mismatch in November is a CP2100 notice avoided in August. Pair with Bookkeeping master-data hygiene and file the match log with the PBC packet.

FAQ

Do we file 1099 for LLCs?

Generally 1099-NEC for individuals, partnerships, and LLCs taxed as such for $600+ services; corporations usually exempt except attorney/medical. Confirm with current instructions and W-9.
