Switching from Paychex to Gusto involves more than moving an employee list. You need to preserve payroll and tax records, transfer accurate year-to-date totals, rebuild deductions and policies, determine which provider will handle each filing, and test the first payroll before ending services.
This seven-step guide focuses primarily on Paychex Flex payroll. Businesses leaving a Paychex professional employer organization (PEO) require additional planning, as ending a co-employment relationship can affect tax reporting, year-end forms, benefits, workers’ compensation, and contract obligations.
Why might a business switch from Paychex to Gusto?
A business might consider Gusto when it wants published plan pricing, month-to-month payroll software, unlimited payroll runs, or a platform oriented toward small and midsize employers.
Paychex and Gusto both offer payroll, payroll tax administration, HR tools, benefits services, time tracking, and employee self-service. Their product structures differ. Paychex offers Flex Select, Pro, and Enterprise payroll packages, HR packages, and PEO services. Depending on the package, customers may combine software with an assigned payroll specialist, expanded HR services, insurance or retirement products, or co-employment.
Gusto publishes Simple, Plus, and Premium payroll plans. Its standard payroll plans are month-to-month and include unlimited payroll runs. The plan and add-ons determine access to multistate payroll, time tracking, advanced HR tools, priority support, or a dedicated service advisor.
Paychex may remain a better fit for an organization that wants a PEO relationship, an assigned-specialist service model, or workforce tools for larger and more complex employers. The question is whether Gusto better fits how your business currently manages payroll and HR.

Before switching, identify which Paychex service you have
Confirm the exact products listed on your Paychex agreement and invoices. “Paychex” can describe several different relationships.
Paychex Flex payroll
A Flex customer may use payroll alone or combine it with time tracking, retirement, insurance, benefits, HR tools, garnishment services, or other products. Connected services may have separate agreements or termination requirements.
Paychex HR Pro
Paychex HR Pro combines payroll and financial support with HR guidance, employee benefits, and workforce services. Replacing payroll does not automatically replace every service your organization uses.
Paychex PEO
A PEO enters a co-employment relationship with the client and covered workers. Depending on the agreement, the PEO may provide payroll, HR support, workers’ compensation, benefits arrangements, and employment-tax reporting.
Before leaving a PEO, determine how you will replace or address benefits, workers’ compensation, retirement services, COBRA administration, HR support, state tax accounts, payroll, and year-end forms.
Paychex’s public PEO terms describe account-specific notice requirements and possible transition or early-termination fees. They also state that Paychex may continue to fulfill obligations already incurred, such as reporting federal employment taxes on wages it issued while the PEO service was active.
Do not apply standard Paychex Flex-to-Gusto W-2 instructions to a PEO exit without written guidance from both providers. A PEO transition can involve a change in the entity reporting wages, and employees may appropriately receive separate Forms W-2 for different portions of the year.
How to switch from Paychex to Gusto in seven steps
Step 1: Choose a target payroll and transition date
Choose the first check date you want Gusto to handle, then work backward. Your transition calendar should include the last Paychex payroll, first Gusto check date, data exports, bank verification, tax setup, employee onboarding, benefits changes, testing, contractual notice, and final Paychex responsibilities.
A January 1 transition avoids transferring payrolls from earlier in the calendar year. A quarter boundary can simplify the tax handoff because the former provider can complete the closed quarter before the new provider assumes the next one.
A mid-quarter or mid-year switch is possible, but it requires accurate prior-payroll data and clear confirmation of which provider will make each tax payment and file each return.
Completion check: You have identified both providers’ check dates, the owner of each task, and the deadline for any required notice.
Step 2: Review your Paychex agreements and connected services
Locate the signed service agreement, order documents, pricing schedules, renewal communications, and agreements for add-ons.
Paychex reports in its corporate filings that client arrangements generally lack specified contract periods and may generally be terminated with 30 days’ notice. Treat that only as company-level context. Your signed agreement, product terms, and PEO documents determine the actual notice requirements, fees, and effective date.
Check for:
Required notice and delivery method
The effective termination date
Separately billed services
Final payroll and tax-filing obligations
Refund, credit, and final-charge terms
Benefits, retirement, insurance, or hardware requirements
Data-export and account-access provisions
PEO transition or early-termination fees
Ask Paychex to confirm in writing which products will end, which will remain active, and which tax deposits, returns, and employee forms it will complete. Do not terminate service until Gusto can meet the intended first payroll date and the connected services have a transition plan.
Completion check: You understand the rules for every Paychex service being replaced.
Step 3: Export employee, payroll, and tax records from Paychex
Download records while Paychex Flex is fully active. Do not assume that administrators or employees will retain access to every report or stored document after termination.
Gusto identifies two Paychex reports for its transfer process.
Download Paychex Employee Profile reports
In Paychex Flex:
Open People List.
Filter by worker category and status to include applicable employees, contractors, active workers, and terminated workers.
Select a worker and open the Profile tab.
Select Download Profile to save the PDF.
Repeat for each worker, then combine the PDFs into a single upload file.
Include terminated employees who received wages during the year because their records remain relevant to filings and year-end forms.
Download the Paychex Employee Earnings Record
In Paychex Flex:
Go to Analytics & Reports.
Under Quick Reports, select View All Reports.
Under Payroll Top Reports, choose Employee Earnings Record.
Select Create Report and include all employees.
Use a custom date range, select the employee and company views, and choose Show Each Earning.
Run the report and download the PDF.
Do not substitute a simple year-to-date summary. Gusto’s instructions call for the detailed Employee Earnings Record. The automated Paychex payroll history import is in beta and may not be available in every Gusto account.
Also download or request, where available:
Payroll registers and wage histories
Quarter-to-date and year-to-date summaries
Federal, state, and local payroll tax returns
Tax-deposit confirmations and unemployment rates
Prior-year W-2, W-3, and 1099 forms
Withholding forms, deductions, contributions, and garnishments
PTO balances, benefit elections, and retirement contributions
Workers’ compensation classifications
General-ledger mappings and contractor histories
Service agreements and final invoices
Store the files securely because they contain sensitive employee and payroll information.
Completion check: You have the records needed to reproduce payroll, tax, benefits, and accounting settings.
Step 4: Set up the company and employees in Gusto
Create the Gusto account before entering prior payroll history. Setup may require the legal business name and federal employer identification number, addresses, bank account, company signatory, pay schedules, federal and state tax details, unemployment rates, employee and contractor data, deductions, PTO policies, and integrations.
Plan | Published standard price | Selected included features |
Simple | $49 per month plus $6 per person | Single-state payroll, unlimited payroll runs, tax filings and payments, and basic PTO policies |
Plus | $80 per month plus $12 per person | Multistate payroll, next-day pay, and time tracking |
Premium | $180 per month plus $22 per person | Dedicated service advisor, priority support, custom reports, and payroll migration and account setup |
State tax registration, accelerated payroll options, broker integration, workers’ compensation, time tools, HR resources, and other services may add charges or depend on the plan.
After you add their email addresses, employees and contractors must create their own Gusto accounts. Set a deadline to verify personal information, withholding elections, and payment details.
Completion check: Company, bank, tax, pay schedule, worker, and signatory information are entered, and the remaining setup tasks have owners.
Step 5: Import or enter previous payrolls and reconcile taxes
A mid-year migration requires complete payroll information for checks already issued during the calendar year.
When Paychex transfer automation is available, upload the combined Profile file under Import team members and the Employee Earnings Record during the payroll-history step. Review every imported field. When automation is unavailable, use Gusto’s previous-payroll workflow.
Gusto instructs employers to gather quarter-to-date summaries for completed quarters, individual pay stubs for the current quarter, year-to-date reports, documentation of tax payments, information on outstanding payroll tax liabilities, and records for active and terminated employees.
Reconcile Gusto against Paychex, including gross and taxable wages, federal and state withholding, Social Security and Medicare, unemployment wages, deductions, employer contributions, reimbursements, garnishments, and net pay. Do not approve prior payrolls when totals do not match.
For a standard payroll transition under the employer’s tax identification number, Gusto assigns completed-quarter filings to the prior provider. It begins its quarterly filings with the quarter containing the first Gusto check date. Gusto also requests complete prior payroll information to prepare year-end forms.
A Paychex PEO exit requires separate confirmation. Paychex’s PEO terms state that Paychex may report federal employment taxes for wages it issued while the PEO service was active and may issue Forms W-2 after termination. Confirm the correct treatment with Paychex, Gusto, and a qualified payroll or tax professional.
Completion check: Prior-payroll totals match, and both providers have confirmed responsibility for deposits, returns, and year-end forms.
Step 6: Rebuild payroll settings and test the first run
Payroll history does not recreate every operational setting. Rebuild pay rates, job codes, overtime, bonuses, PTO, deductions, benefits, retirement contributions, garnishments, workers’ compensation codes, departments, accounting mappings, integrations, and approval permissions.
Run a Gusto preview using the same inputs you would have used in Paychex. Compare gross and taxable wages, withholding, Social Security and Medicare, deductions, employer taxes, PTO, net pay, and accounting entries.
A parallel test means comparing calculations rather than submitting two live payrolls. Processing the same payroll through both providers could duplicate payments, tax collections, or filings. Resolve every unexplained difference before approving the first live payroll.
Completion check: The test calculation has been reviewed and reconciled.
Step 7: Coordinate the final Paychex payroll and go live in Gusto
Before submitting the first Gusto payroll:
Confirm the final Paychex check date and stop future automatic runs.
Ask Paychex which tax deposits it still holds and which returns it will file.
Confirm who will prepare W-2, W-3, 1099, and other annual forms.
Confirm termination dates for payroll and each add-on.
Preserve cancellation confirmation and written tax instructions.
Review the effective dates of benefits, retirement, and workers’ compensation.
Confirm employee onboarding and the payroll-funding account.
For a standard Paychex Flex payroll switch, Gusto states that it will prepare year-end forms when the previous payroll data is complete. Confirm that Gusto has accepted the data before instructing Paychex not to create overlapping forms.
For a PEO exit, do not use that instruction without account-specific confirmation. Paychex may remain responsible for reporting wages it issued while the PEO relationship was active.
Run the first Gusto payroll and compare the final register with the approved test. After settlement, review the final Paychex invoice and confirm that all intended services have ended. Continue monitoring provider accounts and tax agency correspondence for notices related to earlier periods.
How does a mid-year Paychex-to-Gusto switch work?
A mid-year switch requires complete payroll history for every check already issued and a documented division of tax responsibilities.
Gusto requests completed-quarter summaries and detailed records for the current quarter. For a standard payroll transition, the guidance assigns completed quarters to the previous provider and the quarter containing the first Gusto check date to Gusto. Confirm the arrangement before ending Paychex service.
Also verify whether Paychex holds undeposited taxes. A PEO transition can work differently because the PEO may have reported wages and taxes under a different tax-reporting arrangement. Confirm whether employees should receive one combined W-2 or separate forms for pre- and post-PEO wages.
Employers using payroll service providers generally remain responsible for their federal employment-tax obligations.

What happens to your Paychex data after cancellation?
Public Paychex materials do not establish one universal post-cancellation access period for every payroll customer.
Paychex’s PEO terms state that termination or suspension of a Paychex Flex account may result in the loss of access to stored information and make the customer responsible for retaining its records. Take the same precaution with a standard Flex migration:
Export records before ending access.
Store copies outside Paychex Flex.
Confirm how employees will receive prior pay stubs and tax documents.
Ask whether limited access for administrators or employees will remain.
Obtain written confirmation of outstanding filing responsibilities.
The IRS generally requires employers to retain employment tax records for at least 4 years after filing the fourth-quarter return for that year.
What changes when you move payroll to Gusto?
Gusto publishes its standard payroll prices and describes its payroll plans as month-to-month. Standard plans include unlimited payroll runs, while HR, time, support, benefits, and accelerated payment features vary by plan or add-on.
The transition may also require employees to self-onboard, payroll to be entered or imported before the transition, and PTO, deductions, time, benefits, and accounting settings to be recreated. Contracts, employee documents, historical reports, custom fields, retirement services, and some benefit arrangements will not necessarily transfer automatically.
Reconcile payroll registers, tax debits, benefit invoices, retirement contributions, and general-ledger entries during the first several payroll cycles.

Frequently asked questions
How long does it take to switch from Paychex to Gusto?
There is no universal timeline. Gusto markets a switch in fewer than seven days, but that is not a guarantee of planning. Contract notice, bank verification, tax accounts, incomplete records, employee onboarding, benefits, and PEO requirements can extend the process.
Can I switch from Paychex to Gusto mid-year?
Yes. Import or enter every payroll issued earlier in the year, reconcile year-to-date wages and taxes, and confirm which provider will handle the transition quarter and annual forms. A PEO exit may require separate tax reporting and W-2s.
How do I export payroll history from Paychex Flex?
Go to Analytics & Reports, open View All Reports, and select Employee Earnings Record under Payroll Top Reports. Include all employees, use a custom date range, show each earning, and download the report as a PDF.
Will I lose access to Paychex Flex after canceling?
Paychex does not publish one access period for every payroll product. Its PEO terms state that access to stored information may be terminated upon account termination or suspension. Download records before terminating service.
Does Paychex charge an early termination fee?
It depends on the service and agreement. Paychex reports that its general client arrangements usually lack fixed terms and may be ended with 30 days’ notice, but the customer’s contract controls. PEO terms allow account-specific transition and early-termination fees.
Is Gusto cheaper than Paychex?
A reliable comparison requires a current Paychex quote and an equivalent Gusto configuration. Include payroll, per-person charges, tax services, HR, time tracking, support, benefits, retirement, workers’ compensation, implementation, and add-ons.
Who prepares W-2s after a mid-year switch?
For standard payroll, Gusto says it will prepare year-end forms when complete prior provider history is provided. A Paychex PEO exit may require Paychex to issue a W-2 for PEO-paid wages and another provider to issue one for later wages.
Should I run payroll through both providers as a test?
Do not submit duplicate live payrolls. Create a Gusto preview and compare wages, taxes, deductions, employer contributions, PTO, and net pay with the expected Paychex calculation.
