Running payroll for exactly one person sounds like it should be trivial - and the software is the easy part. The real reason solo operators need payroll software is usually tax compliance: an S-corporation owner who has to pay themselves a 'reasonable salary,' a single-member business with one W-2 employee, or a founder who just hired their first teammate. In all of these cases the hard work isn't cutting the check, it's withholding, filing, and remitting payroll taxes correctly every quarter. Good software does that automatically.

Who actually needs one-employee payroll

S-corp owners: the IRS requires owner-employees to take a reasonable W-2 salary before distributions, which means real payroll with withholding and quarterly filings.
Single-employee businesses: you hired one person and now owe federal, state, and sometimes local payroll taxes plus year-end W-2s.
Household and solo employers: you want direct deposit and automatic tax filing without a bookkeeper.

If you are a true solo business owner taxed as a sole proprietor or single-member LLC (not an S-corp), you generally do not run payroll on yourself at all - you take owner draws and pay estimated taxes. Payroll software matters the moment a W-2 is involved.

What to look for

Automatic tax filing: federal, state, and local withholding, deposits, and quarterly/annual returns handled for you.
Flat, predictable pricing: at one employee, the monthly base fee dominates, so transparency matters more than the per-employee rate.
Year-end forms included: W-2 and 1099 processing with no surprise fee.
S-corp friendliness: easy owner-salary setup and the ability to add benefits or a solo 401(k) later.
Room to grow: the same tool should handle employee number two without a migration.

Best overall payroll software for one employee

Gusto

Visit Gusto →

For a one-employee business - especially an S-corp owner paying themselves - Gusto is our top pick. It runs full-service payroll with automatic federal, state, and local tax filing on every plan, includes W-2 and 1099 processing, and makes owner-salary setup genuinely simple. Pricing is published as a base fee plus a per-employee rate, so you know the all-in cost up front, and it scales cleanly the day you add a second person. For solo operators who want payroll handled correctly without hiring a bookkeeper, it's the easiest to run.

Pros

✓ Automatic tax filing on every plan, including year-end W-2s
✓ Simple S-corp owner-salary setup
✓ Transparent, published base + per-employee pricing
✓ Scales from one employee to a growing team with no migration

Cons

✕ US-only
✕ At one employee the base fee makes the per-person cost feel high relative to a big team

A lower-cost alternative

If budget is the single biggest constraint and you want the leanest possible full-service payroll for one person, there are bare-bones providers built specifically for one-to-a-handful of employees. They can be cheaper than a mainstream all-in-one plan, but you typically trade away benefits administration, HR tools, and polish. For most S-corp owners the small premium for an all-in-one like Gusto pays for itself in time saved and room to add benefits later.

How to choose

Confirm automatic tax filing is included - this is the whole point of paying for payroll at one employee.
If you're an S-corp owner, make sure owner-salary and distributions are easy to set up.
Budget on the base fee plus one per-employee seat, and check what a second hire would add.
For most one-employee US businesses, start by pricing Gusto, then compare a budget provider only if cost is the deciding factor.

The bottom line: at one employee you're buying tax compliance and peace of mind, not fancy features. A transparent, full-service tool that files your payroll taxes automatically is worth far more than the few dollars a month you'd save going bare-bones - and it won't slow you down when you hire person number two.
