Payroll setup guide for small business.
Running your first payroll isn’t one task — it’s a sequence: get an EIN, register with the right state agencies, classify each worker correctly (W-2 vs 1099), set a pay schedule, configure withholding, choose a payroll provider, and connect the whole thing to your books and a filing calendar. Below: what each step actually requires, in order, and where it’s worth bringing in a ProAdvisor or a payroll specialist. One note up front — your payroll provider processes payroll and files your payroll taxes; we set it up and keep the books tied to it.
Setting up payroll means putting the legal, tax, and bookkeeping pieces in place before a single paycheck goes out.
That means a federal EIN, the right state registrations (income-tax withholding and unemployment), correct worker classification (W-2 employee vs 1099 contractor), a pay schedule, withholding configured from each worker’s W-4 and your state forms, a payroll provider to run it, and a connection between that provider and your accounting file so the books and the deposit/filing calendar stay accurate. The provider runs payroll and remits and files the payroll taxes for subscribers; TechBrot sets the system up correctly and reconciles it into the books. Multi-state, prior-period errors, or worker-classification doubt are where a CPA or payroll specialist should be involved.
What “setting up payroll” really means.
Setting up payroll is the work that has to happen before the first paycheck: registering with the government so you can legally withhold and remit taxes, deciding correctly whether each worker is an employee or a contractor, configuring how much to withhold, and choosing the software that runs it all. Most owners think of payroll as “the software,” but the software is the last step — it only works if the foundation under it is right. Get the EIN, the state registrations, and the worker classification wrong and you create problems that surface months later as penalties, amended filings, or a misclassification dispute.
Here’s the clear division of labor. The payroll provider — QuickBooks Payroll or another service — calculates each paycheck and, on a full-service plan, files the payroll-tax returns and remits the deposits for its subscribers. That is the provider’s job, and we don’t do it for you. What TechBrot does is set the foundation up correctly, connect the provider to your accounting file, and reconcile payroll into the books so wages, taxes, and liabilities land in the right accounts every run. Where it gets genuinely complex — multiple states, prior-period mistakes, or a classification that’s a close call — that’s when a CPA or a dedicated payroll specialist should be at the table.
What payroll setup actually requires.
Six foundations have to be in place before you run payroll. The step-by-step setup below puts them in order — skip one and it surfaces later as a penalty or an amended filing.
Requirement 01 · A federal EIN
Before you can pay anyone you need an Employer Identification Number from the IRS — the federal account that payroll-tax deposits and filings are tied to. It’s free to obtain directly from the IRS and is the first thing every payroll provider asks for. Without it, nothing downstream can be set up correctly.
Requirement 02 · State registrations
Each state where you have employees generally requires you to register for income-tax withholding and for state unemployment insurance, and to obtain the matching account numbers and rates. These are separate from the EIN and separate per state. Get them in place before the first run so deposits and returns are filed under the right accounts.
Requirement 03 · Correct worker classification (W-2 vs 1099)
Each worker is either a W-2 employee or a 1099 independent contractor, and the distinction turns on the actual working relationship — how much you direct and control the work — not on preference. Misclassifying an employee as a contractor is a frequent and expensive error. When it’s a close call, have a CPA or employment specialist decide before onboarding.
Requirement 04 · A pay schedule and withholding setup
Decide how often you pay — weekly, biweekly, semimonthly, or monthly — and configure withholding from each employee’s federal Form W-4 and the equivalent state forms. The pay schedule and the withholding settings drive every calculation, so they have to be right before the first paycheck rather than corrected after.
Requirement 05 · A payroll provider
A payroll provider — QuickBooks Payroll, an Intuit product, or a third-party provider — calculates paychecks and, for subscribers on a full-service plan, remits and files the payroll taxes. Choose one that fits your size, states, and budget. Setup means entering company, employee, bank, and tax-account details accurately; the provider does the running and filing, not us.
Requirement 06 · A connection to the books and a filing calendar
Finally, the payroll provider has to connect to your accounting file so wages, employer taxes, and liabilities post to the right accounts and reconcile each run — and you need a clear deposit and filing calendar so nothing is missed. This is the piece owners skip, and it’s the one that keeps the books accurate as payroll runs.
How to set up payroll, step by step.
Six steps, in order. Work through them before the first pay run — if you hit multi-state, a classification you’re unsure of, or a prior-period mistake, stop and bring in a specialist.
- 1
Get your federal EIN
Apply for an Employer Identification Number directly from the IRS — it’s free and usually issued immediately online. This is the federal account all payroll-tax deposits and filings attach to, and every later step depends on it, so do it first.
- 2
Register with your state agencies
In each state where you have workers, register for income-tax withholding and state unemployment insurance and record the account numbers and rates you receive. These are per-state and separate from the EIN; with employees in more than one state, this is the point to involve a specialist.
- 3
Classify each worker and collect their forms
Decide whether each worker is a W-2 employee or a 1099 contractor based on the actual working relationship, then collect the right paperwork — Form W-4 and Form I-9 for employees, Form W-9 for contractors. If a classification is a close call, get a CPA or employment specialist to confirm before you onboard.
- 4
Set a pay schedule and configure withholding
Choose your pay frequency — weekly, biweekly, semimonthly, or monthly — and enter each employee’s withholding from their W-4 and the matching state form. These settings drive every paycheck calculation, so confirm they’re accurate before the first run rather than fixing them afterward.
- 5
Choose and configure a payroll provider
Select a payroll provider that fits your size, states, and budget, then enter your company details, EIN and state accounts, employee records, and the bank account for funding payroll. The provider calculates each paycheck and, for subscribers, remits and files the payroll taxes — your job here is to enter every detail accurately so it does so correctly.
- 6
Connect payroll to the books and set the calendar
Link the payroll provider to your accounting file so wages, employer taxes, and liabilities post to the right accounts, then run the first payroll and confirm it reconciles. Set a deposit and filing calendar so deadlines aren’t missed. If the first runs don’t tie out — or you’re multi-state or correcting prior periods — stop and bring in a ProAdvisor or payroll specialist.
When to get help with payroll setup.
You have workers in more than one state
Multi-state payroll multiplies the registrations, withholding rules, and unemployment accounts you have to manage, and reciprocity and nexus questions get complicated fast. That’s the point to have a CPA or payroll specialist set it up — getting it wrong across states is expensive to unwind.
A worker classification is a close call
If you’re unsure whether someone is a W-2 employee or a 1099 contractor, don’t guess. Misclassification carries back taxes, penalties, and benefit exposure, and the test turns on facts a specialist should weigh. Get a CPA or employment specialist to decide before you onboard the worker.
There are prior-period mistakes to correct
If payroll was already run with the wrong setup — a missed registration, a misclassification, or withholding errors — the fix usually means amended filings and reconciling the books back to reality. That’s cleanup and specialist work, not a fresh setup, and the sooner it’s addressed the smaller it stays.
A QuickBooks ProAdvisor sets up payroll and ties it to the books.
Choosing software is the easy part. The work that actually keeps payroll clean is everything around it: confirming the EIN and state registrations are in place, classifying each worker correctly so you’re not exposed on misclassification, configuring withholding from the W-4 and state forms, and then connecting the provider to your accounting file so wages, employer taxes, and liabilities post to the right accounts and reconcile every run. A QuickBooks ProAdvisor holding the Intuit QuickBooks Certification Level 2 does that against a written scope and verifies the first runs tie out before stepping back. The provider, not us, calculates the paychecks and files the payroll taxes for its subscribers — and anything multi-state, prior-period, or a close-call classification goes to a CPA or payroll specialist. Independent firm — not Intuit, and not your payroll tax filer.
What people ask about setting up payroll.
Is this Intuit’s official QuickBooks or payroll support?
No. TechBrot is a bookkeeping and advisory firm. For an Intuit account, login, subscription, or billing issue, or for support of a QuickBooks Payroll subscription, contact Intuit directly; we can’t access your Intuit account. What we do is set payroll up correctly and reconcile it into your books.
Do you file my payroll taxes?
No. For subscribers, your payroll provider — QuickBooks Payroll (an Intuit product) or a third-party provider — calculates each paycheck and, on a full-service plan, remits and files the federal and state payroll taxes on your behalf; confirm with a third-party provider which filings your plan includes. That’s the provider’s service. We set the payroll system up correctly and reconcile payroll into your books; we are not your payroll tax filer.
What do I need before I can run my first payroll?
A federal EIN from the IRS; state registrations for income-tax withholding and unemployment in each state where you have workers; correct classification of each worker (W-2 vs 1099) with the right forms collected; a chosen pay schedule; withholding configured from each W-4 and state form; a payroll provider set up with your company and employee details; and a connection from the provider into your accounting file with a deposit and filing calendar.
How do I decide if a worker is W-2 or 1099?
It turns on the actual working relationship, not convenience. Broadly, a W-2 employee is someone whose work you direct and control, while a 1099 contractor runs an independent business and controls how the work gets done. Misclassifying an employee as a contractor is a costly mistake — back taxes, penalties, and benefit exposure. When it’s a close call, have a CPA or employment specialist make the determination before you onboard the worker. This page is general information, not legal advice.
Which payroll provider should I use?
There are several good options — QuickBooks Payroll (an Intuit product) and third parties such as Gusto are common choices — and the right one depends on your size, the states you operate in, your budget, and how it connects to your books. We can help you weigh providers and set up whichever you choose, but we don’t process payroll or file payroll taxes ourselves; the provider does that for its subscribers.
Can you set up payroll if I have employees in more than one state?
Multi-state payroll adds registrations, withholding rules, and unemployment accounts in each state, plus reciprocity and nexus questions. We’ll help map it and connect it to your books, but the setup itself should involve a CPA or payroll specialist so the cross-state registrations and rules are right from the start. See our multi-state payroll page for how that works.
What does it cost to get payroll set up?
It starts with a free discovery call where we map your EIN, state registrations, worker classification, and provider setup and confirm what’s actually needed. From there we scope the setup work in writing before anything begins. Your payroll provider’s subscription is a separate cost paid to the provider — that’s what runs payroll and files the payroll taxes for subscribers, not us.
What if payroll was already set up wrong?
If payroll was run with a missed registration, a misclassification, or withholding errors, the fix usually means amended filings plus reconciling the books back to reality — cleanup work rather than a fresh setup. The sooner it’s addressed the smaller it stays. We’ll review it on a discovery call and route prior-period corrections to a CPA or payroll specialist where they belong.
