First Payroll Timeline for New LLCs in 2026: Which Accounts Cannot Wait Across States

August 20, 2026

First payroll timeline for new LLCs in 2026 starts with one number that everything else depends on: the Employer Identification Number from the IRS.

A founder forms an LLC in January, hires the first employee in March, and assumes the business checking account is enough to run payroll. The checking account is not enough. The IRS needs an EIN before a payroll tax return can be filed. The state needs a state employer account before unemployment insurance can be remitted. The workers comp carrier needs a policy number before payroll can be processed. Each of these steps has a sequence. The EIN must come before the state employer account. The state employer account must come before the first payroll run. Running payroll without the accounts in place creates tax liability the LLC did not intend and penalties that accumulate from day one of employment.

The EIN first: why the IRS number must come before anything else

The Employer Identification Number is the federal tax ID for the business. It is free, it takes minutes to get online, and it is required for every other employer account. The IRS issues EINs immediately at irs.gov. No phone call, no mail, no appointment. The LLC applies, receives the number, and moves to the next step. Every state employer registration form asks for the EIN. Every workers comp application asks for the EIN. Every payroll software setup asks for the EIN. Treating the EIN as the first task on the first day of hiring is the move that keeps every following step from stalling.

State employer accounts: the next step most new LLCs forget

Each state runs its own employer payroll tax system. The LLC must register with the state’s Department of Labor or Revenue to get a state employer account number. This account is separate from the federal EIN. The state uses this account to track unemployment insurance contributions, state income tax withholding, and in some states disability insurance. Registration is typically online and takes one to five business days. Some states require the employer to register before the first payroll is run. Running payroll and withholding state taxes before registering creates a retroactive liability with interest from the first pay date.

The IRS topic on employer tax responsibilities covers the federal side of employer accounts, including which taxes are owed and when deposits are due.

Unemployment insurance: the account that cannot wait until the first payroll

State unemployment insurance is required in every state. The LLC pays into the state UI fund based on wages. New employers in most states pay a set rate for the first few years before the experience rate kicks in. The UI account must be established with the state before the first payroll is processed. The payroll software cannot withhold UI from employee wages if the employer account does not exist in the state’s system yet. The result is a shortfall in the deposit that the state will notice and assess penalties for, even if the LLC intended to pay everything on time.

Workers compensation insurance: the account that varies by state

Workers compensation insurance is required in almost every state. Some states require it from day one of employment. Others allow a short grace period. A few states let sole proprietors skip it for themselves but require it for employees. The key is checking the requirement in the specific state before the first paycheck is issued. A workers comp policy has to be active before payroll is run in states that require it from day one. The LLC picks a carrier, gets a policy, and gets a policy number before the first hire’s start date. Some states let the LLC use the state’s assigned risk pool if a private carrier declines to write the policy.

The DOL state workers compensation pages have the specific requirements and new employer instructions for each state.

Payroll software and bank account setup

Once the EIN, state employer account, UI account, and workers comp policy are in place, the LLC sets up the actual payroll process. Most new LLCs use payroll software for this. The software asks for the EIN, the state employer account number, the state UI account number, and the workers comp carrier information. The LLC enters this data, runs the first payroll, and the software handles the withholding calculations, direct deposit, and tax deposits going forward. Setting up the software before the hire date means the first paycheck goes out on time. Setting it up after the hire date means the LLC is scrambling to make a same-day payroll run without the account numbers in the system.

A separate business bank account for payroll is not a legal requirement in every state, but it is the cleanest way to keep payroll taxes separate from operating funds. The LLC designates one account for payroll, funds it before each payroll run, and lets the payroll software handle the rest. Mixing payroll funds with operating funds creates accounting complications that compound over time, especially when the LLC grows and the books need to be reviewed for the first tax filing.

The timeline in practice: what happens in what order

Day one: apply for the EIN at irs.gov and receive it immediately. Day two or three: register with the state Department of Labor for a state employer account and a state UI account. Day three to five: apply for workers comp insurance and receive the policy number. Day five to seven: set up payroll software with all account numbers in place. Day seven or whenever the hire date is: run the first payroll with all accounts active. This sequence assumes the LLC is starting from scratch. The timeline can compress if the state allows faster registration or if the workers comp carrier issues a binder quickly. The EIN must always be first.

Multi-state complications: what changes when the LLC is in one state and the employee is in another

The employer accounts above apply to the state where the LLC is formed. When the employee works in a different state, the LLC may also need to register as an employer in that state. This is called foreign employer registration and it works the same way as foreign LLC registration. The LLC registers with the state where the employee works, gets a foreign employer account, and withholds taxes for that state’s system. The LLC ends up with two state employer accounts: one for the home state and one for the remote state. The payroll software handles multiple state withholding if it is set up to do so. The risk is running payroll for a remote employee before the foreign employer account is active in that state.

The multi-state compliance calendars guide covers how to track deadlines and registrations across multiple states, which applies to multi-state payroll compliance as well.

The most common mistake new LLCs make on first payroll

The most common mistake is running payroll before the state employer account exists. The LLC withholds federal and state taxes from the employee’s paycheck, sends the money to the IRS, and then cannot file the state payroll tax return because the state does not have a record of the employer yet. The result is a discrepancy between what was withheld and what the state has on file. The state sends a notice. The LLC pays a penalty for late registration plus interest on the late payments. The fix is simple: register with the state before the first payroll is processed. It takes a few days and it eliminates a compliance problem that otherwise lingers for months.

First payroll timeline for new LLCs in 2026 comes down to this: EIN first, state employer account second, UI and workers comp third, payroll software fourth, first paycheck last. Every step builds on the one before it. Skipping a step does not save time. It creates a penalty that takes more time to resolve than the original task would have taken.
