What Your CPA Needs From Your Payroll Provider at Year-End

Every year around the same time, the same conversation happens between businesses and their accountants. The CPA sends a list of what they need. The business owner goes to their payroll system. Something doesn’t match, something’s missing, or the report is in a format that requires manual reformatting before it’s useful. Then someone spends a few days cleaning up data that should have been clean already.

This isn’t a CPA problem. It’s a payroll system problem. When your payroll provider doesn’t give your accountant clean, accessible data in a format they can actually use, year-end takes longer, costs more in accounting fees, and creates compliance risk when deadlines get tight.

Here’s exactly what your CPA needs from your payroll provider at year-end — and what to look for in a platform that makes this process run smoothly.

W-2s and W-3 Transmittal

W-2s are the year-end requirement most businesses think of first — and they’re where errors compound fastest. Every W-2 that goes out with incorrect wages, incorrect withholding, or an incorrect address creates a correction filing (W-2c) that adds time and cost on both ends. Your payroll provider should generate W-2s automatically from payroll records, distribute them to employees by the IRS deadline of January 31, and file the W-3 transmittal with the Social Security Administration without requiring manual intervention from your team.

Your CPA needs to verify that W-2 totals reconcile with your quarterly 941 filings. If wages reported on W-2s don’t match deposits reported quarterly, that discrepancy needs to be explained before filing. A payroll system that keeps those records connected and accessible saves your accountant significant reconciliation time.

Quarterly and Annual Payroll Tax Reports

Your CPA needs access to your 940 (annual FUTA) and 941 (quarterly federal) filings, plus state unemployment and withholding returns. These documents confirm that tax deposits were made correctly and on time throughout the year. When a payroll provider handles tax filing on your behalf — as Netchex does — your accountant needs confirmation of what was filed and paid, along with documentation they can match to your tax records.

Gaps in this documentation are a common source of year-end stress. If your payroll provider files taxes but doesn’t give you easy access to the underlying records, your CPA ends up asking for things your payroll team has to hunt down. A platform with an accountant portal or clean export functionality eliminates that hunt entirely.

Payroll Registers and Wage Summaries

A full-year payroll register — showing gross wages, deductions, net pay, and employer taxes by pay period — is essential for your CPA to complete your business tax return accurately. They need to know total compensation expense, employer payroll tax costs, and how wages break down by employee type.

Your CPA also needs a department or cost center breakdown if your business allocates labor costs across multiple locations or divisions. Manual allocation from a payroll register is time-consuming. A payroll system with built-in reporting tools that can run a cost-center wage summary in minutes saves your accountant hours they’d otherwise bill to you.

Benefits and Deduction Records

Your CPA needs documentation of pre-tax deductions — health insurance premiums, FSA and HSA contributions, 401k deferrals — to confirm they’re reflected correctly in taxable wages. If your benefits and payroll run on separate systems, reconciling these numbers is a manual exercise that introduces error risk.

Employer 401k contributions are a specific area where accountants run into problems. The total employer match and any profit-sharing contributions need to reconcile with what your plan administrator reports on the Form 5500. When payroll and benefits live in the same system, that reconciliation is straightforward. When they don’t, it requires pulling data from two sources and hoping they agree.

Workers’ Compensation Payroll Records

Workers’ comp premiums are calculated on payroll. At year-end audit time, your carrier needs payroll data broken out by job classification code. Your CPA needs that same data to reconcile workers’ comp expense on your books. A payroll system that tracks job codes and produces a workers’ comp wage audit report removes manual work from both sides of that process.

How Netchex Makes Year-End Easier for You and Your CPA

Netchex handles W-2 generation, tax filing, and payroll records in one connected platform — which means the data your CPA needs is always in one place, not scattered across multiple systems. The Netchex CPA partner program gives accountants direct access to client payroll data through a dedicated portal, so they’re not waiting on someone to pull and send reports. That saves time on both sides of the relationship.

When benefits administration and payroll run in the same system, pre-tax deduction reconciliation is built in rather than bolted on. Quarterly tax filings are stored and accessible. Year-end reports run in minutes, not days. That’s the experience CPAs cite when they recommend Netchex to clients — and the reason businesses who’ve gone through year-end with a disconnected system don’t go back.
