What you get
What professional payroll services cover
A modern payroll provider runs payroll, files every tax, issues year-end forms, and stays current on compliance — so you don't have to.
Multi-state W-2 payroll
Run payroll across every state where employees work, with state registrations and SUI rates handled.
1099 contractor pay
Pay contractors on-demand, classify them correctly, and file 1099-NECs at year-end.
Tax filings & deposits
Federal 941/940, state withholding, SUI, and local tax deposits filed on time, every period.
Benefits & HR integration
Health, 401(k), HSA/FSA, paid leave, and PTO accruals integrated with each payroll run.
Bundle
Payroll + bookkeeping bundle
When your payroll provider also keeps your books, your wage and tax data flows straight to the general ledger — no manual journal entries, no end-of-year scramble.
- Payroll entries auto-posted to QuickBooks Online, Xero, or Sage with proper wage/tax/benefit splits
- Workers comp audit data pulled directly from payroll classes — no separate reconciliation
- 401(k) contribution and match accruals tracked monthly, not just at year-end
- Cash flow forecasts driven by actual pay-period and tax-deposit dates
- One vendor relationship, one bill, one team that knows your books and your payroll
- Year-end W-2 / 1099 / 1095-C production reconciled to the GL before filing
Compliance
Payroll compliance checklist
The compliance surface area for payroll is huge — federal, state, local, and industry layers all stack. A professional provider runs this checklist every pay period.
- Federal Form 941 quarterly; Form 940 annual FUTA reconciliation
- State withholding and SUI registration in every state where W-2 employees work
- Local taxes (city wage tax, school district, occupational license, transit tax) collected and remitted
- I-9 employment eligibility verification on file for every employee (and E-Verify where required)
- New hire reporting to the state directory within the statutory window (typically 20 days)
- Workers' compensation policy verified and class codes matched to actual job duties
- Affordable Care Act 1094-C / 1095-C reporting for Applicable Large Employers
- Year-end W-2, W-3, 1099-NEC, and 1096 filing by January 31
State payroll tax
State payroll tax handled
Every state where you have a W-2 employee triggers state withholding, SUI registration, and sometimes paid leave or disability programs. Your provider tracks the full footprint.
- State income tax withholding registered, calculated, and deposited on each state's schedule
- State Unemployment Insurance (SUI) experience rate applied — re-checked at each annual rate notice
- Paid family / medical leave premiums (CA, NY, MA, WA, OR, CO, CT, NJ, RI, DC and growing) collected and remitted
- State disability programs (CA SDI, NY DBL, NJ TDB, RI TDI) tracked at the state-specific wage base
- Reciprocity agreements honored where neighboring states allow withholding to a single state of residence
- Local taxes (PA EIT/LST, OH RITA/CCA, NY NYC, MD county, KY occupational) calculated correctly
New hires
New hire reporting
Every state requires employers to report new hires within a short window (usually 20 days). Late or missing filings trigger state penalties and break child-support enforcement.
- Reports filed with the state new-hire directory the same week the employee starts
- Rehired employees re-reported when they return after 60+ days off payroll
- Independent contractor reporting where the state requires it (CA DE 542, others)
- Federal data shared with the Office of Child Support Enforcement automatically
- Multi-state employers file with a single chosen state under the federal multistate election
Classification
Contractor vs. employee compliance
Misclassifying a worker as a 1099 contractor when they should be a W-2 employee is the single most expensive payroll mistake — back wages, back taxes, penalties, and state audits.
- IRS three-prong test (behavioral, financial, relationship of the parties) documented
- State ABC tests (California AB5, Massachusetts, New Jersey) applied where stricter than federal
- Section 530 safe harbor relied on only with a defensible reasonable-basis position
- Form SS-8 strategy considered before voluntary worker reclassification
- VCSP (Voluntary Classification Settlement Program) used to limit back tax exposure on reclassifications
- 1099-NEC issued by January 31 for every contractor paid $600+ during the year
Year-end
W-2 and 1099 support
Year-end is the single highest-stakes window in payroll. A professional provider produces, distributes, and files every form correctly the first time.
- Form W-2 for every employee; Form W-3 transmittal to the SSA
- Form 1099-NEC for every contractor paid $600+; Form 1096 transmittal to the IRS
- Box-by-box reconciliation of W-2 wages to 941 wages, 940 wages, and the GL
- Health insurance reporting in Box 12 (Code DD); 401(k) in Box 12 (Code D)
- Corrected W-2c and 1099 issued when errors are caught after the filing deadline
- State copies filed with every state that requires them — federal CF/SF program used where eligible

Compare your options
CPA payroll vs. payroll company vs. PEO
Three real paths for outsourcing payroll. The right one depends on headcount, benefits ambition, and how tightly payroll needs to integrate with your books and tax return.
CPA-led payroll
CPA payroll service
- •Payroll runs in software owned by your accounting firm
- •Tax filings tied directly to your year-end return
- •Single point of contact for payroll, books, and tax
- •Compliance advice built into the relationship, not billed by the hour
- •Best when your CPA handles your books and return already
Best for
1–50 employee businesses that already work with a CPA firm
Outsourced payroll company
Full-service payroll company
- •Provider runs payroll and files every federal, state, and local tax
- •Self-service portals for employees and contractors
- •Tax-penalty guarantee on the provider's filings
- •Strong benefits administration add-ons (health, 401(k), HSA)
- •Year-end W-2 and 1099 production included
Best for
1–200 employee businesses that want payroll fully off their plate
PEO co-employment
Professional Employer Organization
- •Provider becomes co-employer of record on your W-2s
- •Fortune-500-grade health insurance, 401(k), and workers comp at small-employer prices
- •Multi-state compliance handled across every jurisdiction
- •Higher cost — typically $150–$200 per employee per month
- •Tradeoff: less control and harder to switch providers later
Best for
10–75 employee growth companies competing for talent on benefits
Software
Payroll software comparison
Most CPA and outsourced payroll providers run on one of these platforms. Knowing the platform helps you compare apples to apples.
| Platform | Best for | Pricing (typical) | Notes |
|---|---|---|---|
| Gusto | 1–50 employee small businesses, modern UX, embedded benefits | $40 base + $6–$12/ee/mo | Easy onboarding, contractor-only plan, strong multi-state support |
| ADP RUN / Workforce Now | SMB through mid-market, deep HR add-ons | Quote-based, ~$59 base + $4–$8/ee | Industry default at scale; complex pricing, requires negotiation |
| Paychex Flex | Small to mid-market, strong PEO option (Paychex PEO) | Quote-based, ~$39 base + $5/ee | Strong workers comp integration; PEO is competitive vs. TriNet/Insperity |
| QuickBooks Payroll | Existing QBO bookkeeping clients | $50 – $130 base + $6–$11/ee/mo | Tightest integration with QBO ledger; native to most CPA firms |
| Rippling | Tech-forward SMBs combining payroll, HR, and IT | $8+/ee/mo for payroll, modular add-ons | Strong global EOR and contractor coverage; can sprawl in pricing |
| OnPay | Restaurants, agriculture, nonprofits, 1–100 employees | $40 base + $6/ee/mo | Single flat plan; strong industry support including tipped wages and clergy |

Common questions
Payroll services FAQs
How much do professional payroll services cost?+
Most outsourced payroll providers charge a monthly base ($40–$180) plus a per-employee fee ($6–$25). PEOs charge $150–$200 per employee per month but bundle Fortune-500 benefits. A payroll + bookkeeping bundle for a 1–25 employee small business typically lands between $300–$1,500/month. See the pricing table above for the full breakdown.
What's the difference between a CPA payroll service and a payroll company?+
A CPA payroll service runs payroll inside your accounting firm — same team that does your books and return. A payroll company (Gusto, ADP, Paychex) is a dedicated payroll vendor. CPA-led wins on integration; full-service payroll companies win on self-service tooling and benefits admin. PEOs sit on top of either with co-employment.
Do I have to use the payroll provider my CPA uses?+
No. Most CPAs work with whichever provider you already have. That said, if your CPA runs payroll natively in QuickBooks Online or Gusto, switching to their stack often simplifies the year-end close and eliminates manual GL entries.
What happens if my payroll provider files taxes late?+
Reputable full-service providers (Gusto, ADP, Paychex, QuickBooks Payroll, OnPay) offer a tax-penalty guarantee — if the provider files late or wrong, they pay the penalties and interest. Always confirm this is in writing before signing.
Do I need to issue 1099s if I use a payroll provider for contractors?+
If you pay contractors through your payroll provider, the provider issues 1099-NEC at year-end. If you pay contractors outside payroll (Venmo, check, ACH), you're responsible — and most CPAs and bookkeepers will issue them for you.
Can payroll providers handle multi-state employees?+
Yes. Modern providers (Gusto, ADP, Rippling, QuickBooks Payroll) handle multi-state payroll natively — registering you in each state, applying the right SUI rate, and filing in each jurisdiction. Some charge an add-on per additional state; others bundle.
Should I move to a PEO?+
PEOs make sense for 10–75 employee growth companies that need Fortune-500 benefits to compete for talent. Below 10 employees the per-head cost rarely justifies the benefit. Above 75–100 you're usually better off going direct on benefits and using a standalone payroll provider.
Who reports new hires — me or the payroll provider?+
Full-service payroll providers file new-hire reports with the correct state directory within the statutory window. If you run payroll in-house or DIY, the responsibility is yours — and the state penalties for missed reports are surprisingly steep.
