Dad’s short answer
Switching payroll with a first payday in January is the cleanest move you can make. Your current provider closes out 2026, Gusto starts 2027 fresh, and there’s almost nothing to re-type.
- Your first Gusto check date in Q1 means Gusto asks only for that quarter’s pay stubs, and there are none if Gusto runs your first January payday.1
- One provider files each quarter, so your current provider handles Q4 2026 and the 2026 W-2s.2
- November and December give you room to set things up at an easy pace.
Why year end is such a natural time to switch
Payroll runs on quarters and calendar years. When you change providers in the middle of one, the new provider has to pick up the year-to-date numbers so the W-2s come out right. When you change at the turn of the year, the old year stays whole with the old provider and the new year starts whole with the new one.
- Fewer numbers to move. The check date, the day people actually get paid, decides which quarter a payroll counts in.1 A first Gusto check date in January keeps the whole of 2026 with your current provider.
- One W-2 per person. After a mid-year switch Gusto files the full year’s W-2s, so it needs everything from earlier in the year.2 At year end, each provider files its own year.
- Fresh state rates. New state unemployment rate notices usually arrive between November and March, so a January start means entering next year’s rate once.3
- A good habit, ready for growth. Starting a new year on a payroll setup you like is one of those small wins that pays off every payday after.
Gusto is the payroll product we use and recommend. The same calendar logic works for any switch, though.

The switch, step by step
- Pick your first Gusto check date. The first payday of January is the classic choice. Work backward from it with the planner.
- Download your year from your current provider. Registers, YTD totals, filed returns, tax payments, employee details. Keep the PDFs in one folder.
- Open Gusto through our referral link. Tell Gusto who you pay, add your company, federal and state tax details and your bank.4
- Set your pay schedule. Choose how often you pay and your first check date. Paying hourly folks? Gusto suggests leaving at least 4 business days between the end of a pay period and payday.4
- Invite your team. People add their own bank details and W-4. Direct deposit info doesn’t carry over from your old provider.9
- Run your last 2026 payroll on your current provider. Then confirm in writing who files what.
- Run your first Gusto payroll in January. Then cancel the old service once its 2026 filings are done and saved.

FAQ
Do I have to switch before January 1?
No. You can switch any time. January is simply the tidiest start, because Gusto only needs the current quarter’s pay stubs when your first Gusto check date is in Q1, and there are none if Gusto runs your first January payday.
Who files my 2026 W-2s if Gusto starts in January?
Your current provider files 2026, including the Q4 941 and the 2026 W-2s. Gusto starts with 2027. Get that in writing from your current provider before you cancel anything.
Is it too late in November or December?
Not at all. Gusto doesn’t file any returns, even $0 ones, until it runs a payroll with a check date in that quarter, so opening your account now and finishing setup at your own pace is fine.
Is this tax advice?
No. It’s how payroll switches work, with sources. Every business is a little different, so check with your CPA for your situation. Good CPAs love a clean switch, and they’re on your team.
