The Ultimate Year-End Payroll & HR Checklist for 2025: What Chattanooga Businesses Must Do Before 2026
The Ultimate Year-End Payroll & HR Checklist for 2025
What Chattanooga Businesses Must Do Before 2026
Year-end payroll is where small mistakes become expensive problems.
For Chattanooga and Tennessee employers, December isn’t just about final pay runs — it’s about tax compliance, reporting accuracy, benefits updates, and HR documentation cleanup before January 1.
If year-end feels rushed, corrections spill into the new year. If it’s structured, January starts clean.
This checklist walks Chattanooga business owners through exactly what must be reviewed before closing out 2025.
Who This Guide Is For
• Chattanooga small and mid-sized businesses • Tennessee employers issuing W-2s or 1099s • Companies paying bonuses or commissions • Businesses with multi-location or tipped employees • Employers wanting a smooth start to 2026
If payroll felt reactive this year, this checklist will help you close it correctly.
1️⃣ Verify Employee Information Before W-2 Processing
Incorrect employee data is the #1 cause of W-2 corrections.
Before your final payroll of 2025, verify:
✔ Legal name (matches Social Security) ✔ Current mailing address ✔ Social Security number ✔ Tax withholding elections (W-4 updates) ✔ Direct deposit information ✔ Benefit deduction totals
Correcting data in December prevents amended W-2s in January.

2️⃣ Reconcile All Wage Categories
Before year-end reporting, confirm totals for:
• Regular wages • Overtime • PTO payouts • Holiday pay • Bonuses • Gift cards (taxable compensation) • Commissions • Tips (hospitality industry) • Mileage reimbursements
Misclassified compensation results in inaccurate W-2 reporting.

3️⃣ Process Bonuses Strategically
Bonuses must be:
✔ Properly taxed ✔ Correctly categorized ✔ Processed before final payroll deadlines
Decide whether bonuses will run:
• As a separate payroll • With regular payroll • Under supplemental tax rates
Communicate clearly with your payroll provider before processing.
4️⃣ Confirm Federal & Tennessee Tax Compliance
As a Tennessee employer, verify:
✔ Federal payroll tax deposits ✔ Tennessee unemployment filings ✔ FUTA credit adjustments ✔ Deposit frequencies ✔ Electronic filing requirements
IRS late payment penalties range from 2%–15% depending on timing.

5️⃣ Review Benefits Before January 1
Most benefit plans renew January 1.
Confirm:
✔ Health insurance rate changes ✔ 401(k) contribution limits ✔ HSA/FSA limits ✔ Employer matching adjustments ✔ Eligibility changes
Incorrect deduction amounts create employee frustration and payroll corrections in Q1.
