🚨 2027 Tax Filing Deadlines
- Jan 31 W-2 & 1099-NEC: Mail to recipients AND file with IRS/SSA (hard deadline)
- Feb 28 1099-MISC (paper): File with IRS (if not e-filing)
- Mar 2 ACA 1095-B/C: Provide to employees (if applicable large employer)
- Mar 31 1099 (e-file): E-file 1099s with IRS (extended deadline vs paper)
- Mar 31 ACA Forms: File 1094/1095 with IRS (if 50+ full-time equivalent employees)
Tax season is when payroll mistakes come home to roost. Miss a deadline? Penalties start at $50 per form and escalate fast. Incorrect W-2? Your employee can't file taxes and blames you. Forget about ACA reporting? The IRS sends you a $310-per-employee penalty letter.
The good news: Modern HR software makes tax compliance automatic. It generates W-2s and 1099s from your payroll data, e-files them directly with government agencies, and gives employees instant digital access to their forms.
Here's how to choose the right platform to survive tax season with your sanity intact.

Common Tax Season Mistakes (And How to Avoid Them)
❌ Mistake #1: Waiting Until January 25th to Start
The January 31 deadline sneaks up fast. If you find errors on January 30th, you're out of time to fix them.
✅ Solution: Generate draft W-2s/1099s by January 10th. Review them for 1-2 weeks before finalizing and filing.
❌ Mistake #2: Name/SSN Mismatches
If an employee's name on your W-2 doesn't match SSA records exactly (maiden names, nicknames, typos), the IRS rejects the filing.
✅ Solution: Verify names against Social Security cards in December. Use SSA's Business Services Online to pre-validate SSNs.
❌ Mistake #3: Forgetting State and Local Tax Forms
W-2s must be filed with the IRS, SSA, AND state tax agencies. Many states have unique filing requirements and deadlines.
✅ Solution: Use payroll software that auto-files state forms (Gusto, ADP, Rippling all handle this). If DIY, check each state's requirements.
❌ Mistake #4: Misclassifying Workers (W-2 vs 1099)
If the IRS determines your 1099 contractor should have been a W-2 employee, you'll owe back payroll taxes, penalties, and interest.
✅ Solution: Use the IRS behavioral control test. If you control how, when, and where they work, they're an employee. When in doubt, consult a CPA.
❌ Mistake #5: Skipping ACA Reporting
If you're an applicable large employer (50+ FTEs) and don't file 1095-C forms, the penalty is $310 per employee. For a 100-person company, that's $31,000.
✅ Solution: Use HR software with ACA tracking built in. It calculates FTE status automatically and generates 1095-C forms.
Tax Season FAQ
Q: Can I e-mail W-2s to employees?
A: Yes, but employees must explicitly consent to electronic delivery. Without consent, you must mail paper W-2s. Most modern payroll software offers an employee portal where W-2s are available for download (which satisfies the electronic delivery requirement).
Q: What's the penalty for filing W-2s late?
A: It depends on how late:
- 1-30 days late: $50 per form
- 31 days to August 1: $110 per form
- After August 1: $290 per form
- Intentional disregard: $580 per form (no cap)
Q: Do I need to send 1099s to incorporated contractors?
A: Generally, no. If a contractor is a C-corp or S-corp, you don't need to send a 1099. However, you DO send 1099s to LLCs (unless the LLC has elected corporate tax status). Check Box 3 on their W-9 to see their tax classification.
Q: What if I make a mistake on a W-2 after filing it?
A: File a W-2c (corrected W-2) as soon as you discover the error. Most payroll software can generate W-2c forms. Don't wait—employees need accurate W-2s to file their taxes, and the IRS won't be happy if discrepancies show up.
Q: Do I need ACA reporting if I have fewer than 50 employees?
A: No. ACA reporting (1095-B/C forms) is only required for "applicable large employers" (ALEs), which means you had 50+ full-time equivalent employees in the prior year. If you're under 50, you're exempt from ACA reporting requirements.
Q: What's the difference between 1099-NEC and 1099-MISC?
A: 1099-NEC is for non-employee compensation (contractors, freelancers). 1099-MISC is for other payments like rent, royalties, prizes, or medical payments. Most small businesses only need 1099-NEC.
Q: Can I e-file my tax forms for free?
A: The IRS e-filing system (FIRE) is free to use, but it's clunky and time-consuming. Most businesses use payroll software that includes e-filing (Gusto, QuickBooks, ADP, etc.). The convenience is worth the cost—you'll save hours of manual data entry.
Q: How long should I keep W-2 and 1099 records?
A: The IRS recommends keeping payroll tax records for at least 4 years. However, many businesses keep them for 7 years to be safe (the IRS can audit up to 6 years back in cases of substantial underreporting).
Final Thoughts: Automate or Suffer
