Contract dates and quarter ends change what a switch costs you. Answer five questions to see whether to move now or hold for a clean break.

This is a planning guide, not tax, legal, or accounting advice. Filing deadlines and contract terms vary, so confirm your notice period in writing and ask any provider to commit to an onboarding date before you cancel anything.
Behind the answer
Two payroll switches with identical providers can cost very different amounts of money and admin, purely because of the date they land on.
Payroll tax returns are filed by quarter. If you move on the first day of a quarter, your old provider closes out the last one and your new provider starts from zero. Move mid-quarter and two providers touch the same return, which is where duplicate filings and mismatched deposits come from.
A move at the start of the year means one provider handles the whole year and each employee gets a single W-2. Any other date means your new provider has to load year-to-date wages and taxes accurately, or your people get two forms and more questions than you want to answer.
Most agreements have a notice window, often 30 to 90 days, and many renew automatically if you miss it. The quiz treats your contract as the earliest realistic exit, then adds the lead time a provider needs to load, validate, and parallel-run your data before the first live payroll.
The quiz weighs how much your current setup is costing you against how much stands in your way, then puts the answer on a calendar. Every date it gives you is a target, not a deadline. Confirm the onboarding window with the provider you pick.
Compare vetted payroll providers side by side and ask each one to commit to your go-live window. It is free, and there is no obligation to switch.
