QuickBooks Payroll · Year-End
Year-end payroll, done right before the deadlines.
Year-end isn’t a single event. It’s a multi-month reconciliation cycle from late November through mid-March — pre-year-end reconciliation, year-end adjustments (bonuses, fringe benefits, group-term life, third-party sick pay), W-2 and 1099-NEC generation, federal and state filings, Q4 Form 941, Form 940 FUTA, and the W-2c amendments that surface in February when employees file their personal returns. Each step carries hard deadlines. We handle the full cycle as a fixed-fee, deadline-driven engagement. Independent firm, not affiliated with Intuit Inc.
Year-end payroll is the multi-month reconciliation cycle — late November through mid-March — that finalizes a year of wages and taxes and produces the W-2s, 1099-NECs, and year-end filings. It is far more than generating forms in January: it spans pre-year-end reconciliation, year-end adjustments (bonuses, fringe benefits, group-term life over $50,000, third-party sick pay, S-corp owner health), the final December payroll, W-2 and 1099-NEC generation and distribution by January 31, federal filing (W-2s to the SSA on Form W-3, 1099-NECs to the IRS), state W-2 transmittals, Q4 Form 941 verification, Form 940 FUTA, and W-2c amendments for prior-year corrections. The most-missed work is the year-end adjustments — they don’t surface in regular cycles and each needs a W-2c if caught late. TechBrot Certified Payroll ProAdvisors deliver year-end fixed-fee and deadline-driven, coordinating with your CPA on the business income-tax return.

Year-end payroll, in five questions.
When are W-2s and 1099-NECs due?
January 31 for both, on two parallel tracks: (1) furnishing forms to employees and contractors; (2) federal filing — W-2s to the Social Security Administration (transmitted on Form W-3), 1099-NECs to the IRS. Most states also require state W-2 filing by January 31. Form 940 FUTA is due January 31, extending to February 10 if all FUTA was deposited on time. Late penalties escalate with delay.
What does year-end actually include?
A multi-month cycle, late November through mid-March: pre-year-end reconciliation; year-end adjustments (bonuses, fringe benefits, group-term life over $50K, third-party sick pay, S-corp owner health); final December payroll; W-2 & 1099-NEC generation; federal filings; state filings; Q4 Form 941 verification; Form 940 FUTA; and W-2c amendments for prior-year corrections.
What goes wrong most often?
Year-end adjustments that don’t surface in regular cycles: missing fringe benefits (vehicle use, housing, awards); group-term life over $50,000 (taxable; W-2 box 12 code C); third-party sick pay not reconciled; S-corp owner health insurance not added to W-2 box 1; bonuses not treated as supplemental wages; and state-specific reconciliation missed. Each needs a W-2c amendment if caught after filing.
What if a W-2 is wrong after filing?
Corrected via Form W-2c (Corrected Wage and Tax Statement), transmitted to SSA on Form W-3c. There is no fixed deadline for W-2c (unlike the original W-2), but it should be filed as soon as the error is identified. Common triggers: a discrepancy found on a personal return, a missed fringe benefit, a wrong Social Security number, or an incorrect wage amount. The employee may need to amend their personal return.
How is it priced?
Fixed-fee, scoped by complexity. Standard (under ~25 employees, minimal adjustments, 1–2 states): $1,500–$3,500. Mid-tier (25–100 employees, significant adjustments, multi-state): $3,500–$7,500. Complex (W-2c amendments, prior-year cleanup, restructuring): $7,500+. Deadline-driven — engage early to clear pre-year-end reconciliation before the January 31 crunch.

Year-end payroll, plainly.
Year-end payroll isn’t generating W-2s in January — it’s a multi-month reconciliation cycle that runs from late November through mid-March. The full scope: pre-year-end reconciliation (verifying year-to-date wage and tax accumulations before final payroll); year-end adjustments — bonus payments with supplemental-withholding decisions, fringe-benefit additions to W-2 income (personal use of a company vehicle, employer-provided housing, taxable awards), group-term life insurance over $50,000 (taxable to the employee; W-2 box 12 code C), third-party sick-pay reconciliation, and S-corporation owner health insurance added to W-2 box 1; final December payroll execution; W-2 generation and distribution to employees by January 31; 1099-NEC generation and distribution to contractors by January 31; federal filings — W-2s with the Social Security Administration (transmitted on Form W-3) and 1099-NECs with the IRS by January 31; state W-2 transmittal filings (most states by January 31); Q4 Form 941 verification; and Form 940 FUTA, the annual federal unemployment return.
The most-missed items are the year-end adjustments — fringe benefits, group-term life, third-party sick pay, S-corp owner health — because they don’t surface during the regular payroll cycle and each requires a W-2c amendment (with a corrected W-3c transmittal to SSA) if missed and discovered later. On pricing, standard year-end for under ~25 employees with minimal adjustments typically scopes $1,500–$3,500; 25–100 employees with significant adjustments scopes $3,500–$7,500; complex year-end including W-2c amendments and prior-year cleanup scopes $7,500+. Services coordinate with your CPA on business income-tax matters and don’t include income-tax filing, IRS representation, audit, or assurance.

Six deadlines that drive year-end work.
Year-end payroll is fundamentally deadline-driven. Each of the six below carries real penalties for missed timing and shapes the engagement schedule.
January 31 · W-2s to employees & SSA
W-2 forms must be furnished to employees AND filed with the Social Security Administration (transmitted on Form W-3) by January 31. The dual requirement matters: mailing employee copies on time is not enough — the SSA transmittal carries the same deadline. Late-filing penalties begin at relatively small per-form amounts and escalate based on how late the filing is.
January 31 · 1099-NECs to contractors & IRS
1099-NEC forms reporting nonemployee compensation (contractor payments of $600 or more in the course of business) must be furnished to contractors AND filed with the IRS by January 31. The 1099-NEC deadline is one date, not split — recipient copies and the IRS filing share the same January 31 deadline.
January 31 · State W-2 transmittal (most states)
Most U.S. states require a state W-2 transmittal (a state-specific form or electronic transmission) by January 31. Specific state deadlines vary — a few states fall in mid-February, and some require annual reconciliation forms that combine the year’s quarterly filings into a single year-end reconciliation.
January 31 (or Feb 10) · Form 940 FUTA
Form 940 (the annual Federal Unemployment Tax return) is due January 31. If you deposited all FUTA tax on time during the year, the deadline extends to February 10. Most small businesses owe minimal FUTA, but the annual filing is still required regardless of the amount due.
January 31 · Q4 Form 941
The Q4 quarterly Form 941 (covering October–December wages) is due January 31. Year-end work includes verifying that Q4 941 reconciles with the cumulative Q1–Q3 941 filings and ties out to the W-2 totals being transmitted to SSA — a mismatch here is the first thing the SSA reconciliation flags.
No deadline · W-2c amendments
W-2c amended forms (transmitted on Form W-3c) carry no fixed deadline — they are filed when an error is identified. Most W-2c work clusters in February–April as employees prepare personal returns and surface discrepancies. Earlier is better: a late W-2c can force an employee to file an amended personal return.
Six categories of work, every engagement.
Year-end work spans more than form generation. The full scope below is what a proper engagement covers — skip any one and you create downstream issues that compound through February and March.
Pre-year-end reconciliation
Before final December payroll: verify year-to-date wage and tax accumulations are accurate. Reconcile the quarterly 941 filings against payroll totals. Identify wage-base issues (the Social Security wage cap, state SUI caps), missing deductions, or reconciliation drift carried from earlier in the year. Catching errors here fixes them before W-2 generation; catching them afterward means W-2c amendments.
Year-end adjustments
The most-missed items. Fringe benefits (personal use of a company vehicle, employer-provided housing, taxable awards) are added to W-2 box 1 with proper tax withholding. Group-term life over $50,000 of coverage is taxable to the employee and reported in W-2 box 12 with code C. Third-party sick pay from a carrier is reconciled against employer records. S-corporation owner health insurance is added to W-2 box 1 (reported in box 14). December bonuses need a supplemental-withholding decision.
W-2 generation & distribution
After adjustments are applied: W-2 generation for each employee, verification against payroll records, distribution to employees (print-and-mail, or electronic with employee consent), and an employee verification window to catch disputes before the SSA filing locks in. All by January 31.
1099-NEC generation & distribution
For every contractor paid $600 or more during the year: 1099-NEC generation from contractor payment totals, verification against vendor records and W-9 documentation, distribution to contractors, and IRS filing by January 31. Distinct from 1099-MISC — since the 2020 tax year, most small-business 1099 reporting is on 1099-NEC for contractor services.
Federal & state year-end filings
Federal: W-2 transmittal to SSA (Form W-3), 1099-NEC transmittal to IRS, Form 940 FUTA annual return, and Q4 Form 941. State: state W-2 transmittal in every state with employees, state-specific year-end reconciliation forms where required, and state 1099 filings in states with separate requirements. Each has its own format and submission method — we handle the coordination.
W-2c amendments & prior-year cleanup
For errors discovered after initial filing — usually February–April as employees file personal returns. W-2c forms (with the W-3c transmittal to SSA) correct missed fringe benefits, wage discrepancies, incorrect Social Security numbers, and missed adjustments, with coordination on amended personal returns where needed. Often a follow-on engagement to standard year-end.
Six items that don’t surface in regular payroll cycles.
The most consequential year-end mistakes cluster around items that never come up in routine payroll. They surface only at year-end — or worse, only when employees find discrepancies on personal returns in March.
Missed fringe benefits
Personal use of a company vehicle, employer-provided housing, taxable awards, and employer-provided meals beyond IRS exclusion rules are imputed income — they must be added to W-2 box 1 wages with employment taxes calculated. Easy to miss because they don’t flow through normal payroll; they’re tracked separately and require a deliberate year-end addition.
Group-term life over $50K
When employer-paid group-term life insurance exceeds $50,000 of coverage, the cost of the excess coverage is taxable to the employee — calculated from the IRS Uniform Premium (Table I) rates by age band — and reported on W-2 box 12 with code C. Frequently missed entirely on a first attempt because nothing in the regular cycle triggers it.
Third-party sick pay unreconciled
Insurance carriers that paid sick pay during the year report those wages on their own records. The employer must reconcile third-party sick-pay records against payroll so each W-2 reflects the correct combination of regular wages and sick pay. Mismatches surface as employee tax-return discrepancies later.
S-corp owner health insurance missed
For an S-corporation shareholder owning more than 2%, employer-paid health insurance is added to W-2 box 1 wages (and reported in box 14) but is not subject to FICA. The owner then takes the self-employed health-insurance deduction on their personal return. A specific S-corp rule that doesn’t apply to other entity types — and one regular payroll never prompts.
Bonus withholding errors
December bonuses allow two supplemental-withholding methods: the flat-percentage method (the federal supplemental rate) or the aggregate method (combined with regular wages). Using the wrong method — or treating a bonus as regular wages without making the supplemental decision — produces withholding that doesn’t match what the employee expects.
State-specific reconciliation missed
Some states require separate annual reconciliation forms beyond the standard quarterly filings (for example, New York’s annual NYS-45 reconciliation or California’s DE 9). These reconcile the year’s quarterly filings against year-end totals and are often overlooked by businesses running year-end without ProAdvisor support, especially multi-state operations.
Fixed-fee, scoped by complexity.
Year-end pricing scales with employee count, adjustment complexity, and the multi-state factor. Engagement timing matters: booking by mid-December means pre-year-end reconciliation and adjustments are handled before December’s final payroll; booking in January means working against the January 31 deadline with less buffer.
$1,500–$3,500
Fits: a small business under ~25 W-2 employees, minimal year-end adjustments, operations in 1–2 states, standard 1099 volume. Includes: pre-year-end reconciliation against the Q1–Q3 941s, basic year-end adjustments (bonuses, basic fringe), W-2 generation and distribution, 1099-NEC generation, federal filings (W-2, 1099-NEC, 940, Q4 941), state W-2 filing in 1–2 states, and a post-filing employee verification window.
$3,500–$7,500
Fits: growing businesses of 25–100 employees, significant year-end adjustments (fringe benefits, group-term life over $50K, third-party sick pay, S-corp owner health), multi-state operations, and larger 1099 volume. Adds: complex year-end adjustments, W-2 generation for 25–100 employees, higher 1099-NEC volume, multi-state W-2 transmittal, state-specific annual reconciliation forms, and an extended post-filing dispute window.
$7,500+
Fits: 100+ employees, multi-entity payroll, W-2c amendments for prior-year corrections, post-year-end employee disputes, or restructuring botched prior-year filings. Adds: W-2c amendments, prior-year cleanup of missed adjustments, multi-entity year-end coordination, 100+ employee processing, and extended dispute resolution. Pricing is always written before any work begins.
The honest scope boundaries.
Year-end payroll sits adjacent to business income-tax work but doesn’t overlap it. Three boundaries we maintain cleanly:
We don’t file business income tax returns
Year-end payroll coordinates with but doesn’t overlap business income-tax filing. Form 1120 (C-corp), 1120-S (S-corp), 1065 (partnership), and Schedule C (sole prop) are filed by your CPA or EA. Our engagement ensures the payroll-side data flowing to those returns is correct — W-2 totals tying to 941 totals, employee compensation reconciled, owner W-2 box 1 wages right for S-corp analysis — but we don’t prepare or file the business returns.
We don’t prepare employees’ personal tax returns
When a W-2c amendment requires an employee to file an amended personal return, we coordinate with the employee and their personal preparer on the implications and timing — but we don’t prepare the employee’s personal return. That work belongs to each employee’s own CPA, EA, or tax software.
We don’t handle IRS/state controversies
If a year-end filing triggers an IRS or state notice, penalty assessment, or controversy, we can help diagnose what happened operationally and provide the underlying records — but the representation work (responding to the IRS, negotiating outcomes, defending positions) belongs to your CPA or EA. We coordinate; they represent.
When work happens, across the cycle.
Year-end isn’t one phase. The work splits across roughly four phases between late November and mid-March. Earlier engagement means cleaner outcomes; later engagement means working under tighter deadlines.
Phase 1 · Late November – mid-December
Pre-year-end reconciliation. Verify YTD wage and tax accumulations, reconcile against the quarterly 941 filings, and identify and queue the year-end adjustments to be processed in December (bonuses, fringe benefits, GTL calculations, third-party sick-pay coordination). The phase where mistakes are cheapest to fix.
Phase 2 · December
Year-end adjustments applied. Bonus payments with supplemental-withholding decisions, fringe benefits added to W-2 income with proper tax handling, group-term life over $50K processed, and S-corp owner health insurance reconciled. The final December payroll runs with every year-end adjustment incorporated.
Phase 3 · January (especially Jan 1–31)
The deadline crunch. W-2 generation, verification, and distribution; 1099-NEC generation, verification, and distribution; federal filings (W-2 to SSA, 1099-NEC to IRS, Form 940, Q4 941); and state filings (W-2 transmittal, state-specific reconciliations). Most engagement time concentrates here.
Phase 4 · February – mid-March
W-2c amendments and prior-year cleanup. As employees file personal returns, discrepancies surface — missed fringe benefits, SSN errors, wage disputes. W-2c work clusters February–April. The phase that pays the bill for anything not caught in Phase 1.
When to engage
Ideal: November/early December — full pre-year-end reconciliation before final payroll. Workable: mid-December–early January — tighter, but still functional. Crunch: late January — working against the deadline with less time to catch issues. Cleanup: February+ — the W-2c and prior-year work that follows.
Ongoing vs annual
Year-end is typically an annual, one-time engagement rather than a monthly retainer. Some businesses pair it with ongoing multi-state monthly compliance as a single annual-plus-monthly arrangement; others book year-end standalone each November/December for that year’s cycle.
