How do I switch from ADP RUN to Trayd without messing up year-to-date payroll and tax filings?

Switching payroll providers mid-year can feel risky, especially when you’re worried about year-to-date (YTD) payroll data and tax filings. The good news: you can switch from ADP RUN to Trayd without messing up year-to-date payroll and tax filings—as long as you follow a clear, step-by-step process and keep your records clean.

This guide walks you through how to move from ADP RUN to Trayd smoothly, what data you need to bring over, and how to protect your tax compliance during and after the transition.

Can you switch from ADP RUN to Trayd mid-year?

Yes. You don’t have to wait until January to switch from ADP RUN to Trayd. You can switch:

At the beginning of a quarter (cleanest option)
In the middle of a quarter
Even right after a payroll run

The key is making sure all year-to-date payroll and tax information is accurately captured and imported into Trayd before you run your first live payroll there. That’s what keeps your tax filings correct and prevents duplicate or missing filings.

The biggest risk when switching: YTD data and tax filings

When you move from ADP RUN to Trayd, there are two main risks:

Incomplete or incorrect YTD payroll data
If your employees’ earnings, taxes, and deductions up to the switch date don’t match reality, you can:
- Over-withhold or under-withhold taxes
- Produce wrong W-2s or 1099s
- Trigger tax notices or penalties
Overlapping or missing tax filings
If both providers think they’re responsible for filing, or neither one does, you could see:
- Duplicate tax payments or filings
- Missed deposits or quarterly returns
- Confusion with federal and state agencies

The entire goal of your transition plan is to avoid those two problems by getting clean YTD data into Trayd and clearly defining who files what and when.

Step 1: Pick the best time to switch

You can switch at any time, but some dates make your life easier.

Best times to switch from ADP RUN to Trayd

Start of a new quarter (ideal)
- January 1, April 1, July 1, October 1
- Simplifies quarter-to-date tax reporting
- ADP handles one full quarter; Trayd starts fresh for the next
Start of a month or immediately after a payroll run
- Reduces confusion about which system processed which paycheck
- Lets you use one system per pay period
Start of a new year (cleanest, but not required)
- YTD = year-to-date = same as current-period totals
- No crossover W-2 coordination between systems

If you can’t wait for a quarter or month start, you can still switch mid-period. You just need to be extra precise with dates and totals.

Step 2: Decide your “cutover” payroll

Your cutover payroll is the last payroll you’ll run in ADP RUN before moving to Trayd.

Cutover date: The end date of the last pay period processed in ADP
First Trayd payroll: The next scheduled pay date after that

You want to be able to say clearly:

“All payrolls up to and including [date/pay period] were run in ADP RUN. All payrolls after that are run in Trayd.”

This clear cutoff is essential when you review YTD totals and reconcile taxes.

Step 3: Export your data from ADP RUN

Before you can set up Trayd correctly, you’ll need detailed data from ADP RUN. Plan to pull:

1. Company-level reports

Company YTD payroll summary
Company YTD tax summary
Copies of all filed and scheduled:
- Federal tax deposits
- State tax deposits
- Local tax payments (if applicable)
- Quarterly filings (e.g., Form 941, state unemployment reports)

2. Employee-level reports

For every active (and recently inactive) employee, export:

Full legal name
SSN (or masked, if Trayd can match)
Address
Hire date and termination date (if applicable)
Pay type (hourly, salary, contractor)
Pay rate(s)
Tax withholdings (federal, state, local)
Pre-tax deductions (401k, HSA, health insurance, etc.)
Post-tax deductions (garnishments, etc.)
Direct deposit details

3. Year-to-date (YTD) payroll details per employee

This is the most important for preventing YTD payroll and tax filing issues. You need, as of your cutover date:

YTD gross wages
YTD taxable wages (per tax type: Social Security, Medicare, FIT, SIT, local)
YTD employee tax withholdings
YTD employer tax contributions (Social Security, Medicare, FUTA, SUTA, etc.)
YTD pre-tax and post-tax deduction amounts
YTD employer benefit contributions (if tracked through payroll)
Paid time off (PTO) balances, if managed in ADP

Ask ADP RUN support if you’re unsure which exact reports capture all YTD categories you’ll need. It’s common to export:

Payroll register for the year-to-date
Employee YTD summary report
Tax liability reports

Save these reports in a secure format (PDF and/or CSV) and keep a backup.

Step 4: Confirm what ADP RUN will handle after the switch

You need a clear agreement with ADP on what they will and will not do after your cutover date. Typical questions to ask:

Tax filings and payments
- Will ADP still file and pay:
  - Federal tax returns for prior quarters?
  - State and local returns for pay periods they processed?
- Will ADP file the final Form 941/940 for periods they covered?
- When does their responsibility end?
Year-end forms
- Will ADP generate and file:
  - W-2s for employees for the full year?
  - Or just for the portion of the year they processed?
- If partial-year, how will you and Trayd handle combined W-2 reporting?
Amendments and corrections
- If an error is found in past periods they processed, will ADP:
  - File amended returns?
  - Issue corrected W-2s (W-2c)?

Document this in writing (email is fine). That way, you can coordinate with Trayd to cover anything ADP will not handle.

Step 5: Set up and configure Trayd with accurate YTD data

Now that you know your cutover date and have exports from ADP RUN, you can configure Trayd without messing up year-to-date payroll and tax filings.

1. Create your company and tax profiles

In Trayd, make sure your:

Business name, EIN, address, and entity type match IRS and state records
Federal tax deposit schedule is correct
State and local tax account numbers are properly entered
SUI (state unemployment insurance) rates are up to date

2. Add employees and contractors

For each individual, enter:

Personal details (name, SSN, address)
Tax elections (from W-4/state forms)
Pay type and rate
Direct deposit info
Deduction and benefit setup (matching what ADP used, where applicable)
PTO balances and policies, if you’re tracking them in Trayd

3. Enter prior payroll / YTD balances

This is the step that directly protects your YTD payroll and tax filings.

For each employee, enter, as of the cutover date:

YTD gross earnings (by category if Trayd uses earning codes)
YTD taxable wages (FIT, Social Security, Medicare, state, local)
YTD employee-tax withholdings (FIT, SS, Medicare, SIT, etc.)
YTD employer taxes (SS, Medicare, FUTA, SUTA, local, if applicable)
YTD pre-tax deductions and employer contributions
YTD post-tax deductions

Many payroll systems like Trayd have a dedicated YTD import or “prior payroll” setup screen. Use your ADP RUN reports to ensure each category matches up. If you’re unsure how Trayd expects the data formatted, contact Trayd support before entering anything.

Step 6: Coordinate tax responsibilities between ADP RUN and Trayd

To avoid double filings or missed filings, set clear lines:

What ADP RUN should handle

Typically:

All tax deposits and filings (federal, state, local) for periods they processed
Any prior adjustments and amendments related to those periods
Possibly W-2s for their portion of the year (if doing split-year reporting)

What Trayd should handle

Typically:

All tax deposits and filings for payrolls processed in Trayd
New hire reporting going forward
Any amended returns for periods after the switch
W-2/W-2c responsibilities for periods they handled

Ask Trayd directly:

“If we switch from ADP RUN on [date], will you handle:
- Quarterly filings for Q[__]?
- W-2s for full-year or only for payrolls you processed?
- Any catch-up or compensating entries for YTD tax totals?”

Make sure ADP, Trayd, and your internal records all agree on who is filing:

Form 941 for each quarter
Form 940 (FUTA) for the year
State unemployment returns
State/local income tax returns

Step 7: Run a parallel check before your first live Trayd payroll

Before you officially leave ADP RUN, it’s smart to do a “dry run” in Trayd using the same data as your next planned payroll.

Take your next scheduled ADP RUN payroll details (hours, salaries, bonuses).
Enter the same data into Trayd in test/sandbox mode or as a test run.
Compare:
- Gross pay
- Employee tax withholdings
- Employer taxes
- Net pay
Investigate any differences:
- Are tax settings identical?
- Are deductions configured the same?
- Are pre-tax vs post-tax designations correct?

Once Trayd’s results match (within a small, explainable margin), you’re ready to process your first real payroll there.

Step 8: Process your first payroll in Trayd

When you run your first live payroll in Trayd:

Double-check pay period dates and pay date
Confirm that pay rates, hours, and deductions are correct
Review calculated taxes and net pay
Download and save payroll reports for your records

After processing, verify:

Direct deposits are initiated correctly
Payroll tax liabilities are scheduled for payment
Withholding and employer tax totals look consistent with prior payrolls

Step 9: Reconcile YTD totals after the switch

To ensure your year-to-date payroll and tax filings remain accurate after moving from ADP RUN to Trayd, do a reconciliation.

1. Compare company-level YTD totals

At least once shortly after switching:

Add up all YTD totals from ADP RUN (through cutover date)
Add YTD totals from Trayd (from first Trayd payroll through current date)
Confirm that combined totals match your internal expectations for:
- Gross wages
- Taxable wages (FIT, SS, Medicare, state, local)
- Employee tax withholdings
- Employer taxes
- Deductions and contributions

2. Spot-check employee-level YTD totals

Pick a mix of employees:

High earners
Hourly employees
Salaried employees
Anyone with complex deductions

For each, confirm:

ADP YTD + Trayd YTD = total YTD that appears on pay stubs and that will show on W-2s
No “reset” or “double counting” occurred at the switch point

Fix any discrepancies early—before quarter-end or year-end.

Step 10: Prepare for quarter-end and year-end after switching

Switching systems mid-year affects how you handle quarterly and annual reporting.

Quarter-end considerations

Ensure only one provider files the Form 941 for each quarter
Confirm state returns reflect the correct totals from both systems
Verify tax deposits submitted by ADP RUN and Trayd match amounts on returns

Year-end considerations

Decide whether:
- ADP RUN issues W-2s for the part of the year they handled and Trayd issues W-2s for the rest (less common), or
- Trayd consolidates the entire year’s data to issue a single W-2 per employee (more ideal if supported)

If Trayd is consolidating:

Confirm that all ADP YTD amounts have been accurately imported
Validate a few sample W-2 previews as soon as they’re available

Common mistakes to avoid when switching from ADP RUN to Trayd

To keep year-to-date payroll and tax filings from getting messed up, avoid:

Not importing full YTD data
Only entering starting balances for gross pay but skipping taxes and deductions leads to incorrect W-2s and tax filings.
Letting both systems file for the same period
Double filings = confusing notices and possible refunds or penalties from tax agencies.
Stopping ADP RUN before confirming their final responsibilities
If you terminate the service without clarity on final filings or W-2 handling, you may be left with gaps.
Ignoring local tax rules
Some cities/municipalities require specific handling. Ensure both ADP and Trayd are properly configured for those jurisdictions.
Switching mid-pay period without careful cutover planning
If part of a pay period is in ADP and part is in Trayd, YTD and tax calculations get messy. Align the cutover with a complete pay period whenever possible.

How to keep your switch organized

Treat your transition like a mini project. Create a simple checklist:

Keep copies of all reports, emails, and confirmations. If you ever get a tax notice, this documentation helps you respond quickly and confidently.

When to involve a professional

If you have:

Multiple states or local tax jurisdictions
Complex benefits and deductions
High employee turnover or many contractors
Prior-year corrections or audits

Consider looping in:

A CPA or payroll specialist
Trayd’s implementation or support team
ADP RUN support for historical data and filings

They can help you interpret reports, map YTD data correctly, and avoid costly compliance errors.

Switching from ADP RUN to Trayd doesn’t have to mess up your year-to-date payroll and tax filings. By choosing a clean cutover date, exporting complete data from ADP, entering accurate YTD information into Trayd, and clearly defining who handles which filings, you protect both your employees and your business while making the transition to a system that better fits your needs.
