Payroll Taxes for New Business Owners: A Practical 2026 Guide to Withholding, Deposits, and Filings
If your business has employees, payroll taxes become part of your weekly or monthly operating rhythm almost immediately. The rules are not optional, but they are manageable once you understand what gets withheld, what your company pays, and when the IRS expects deposits and filings.
This guide breaks payroll taxes into plain English so new business owners can set up payroll correctly, avoid costly mistakes, and stay organized from the first paycheck onward.
What payroll taxes are
Payroll taxes are taxes tied to wages. Some are withheld from employee paychecks, some are paid by the employer, and some are shared between both.
In practice, payroll taxes usually include:
- Federal income tax withholding
- Social Security tax
- Medicare tax
- Additional Medicare tax withholding for high earners
- Federal Unemployment Tax Act (FUTA) tax
- State and local payroll taxes, where applicable
If you are self-employed and do not have employees, your tax picture is different. Payroll taxes generally apply when you pay wages to workers as an employer.
Who is responsible for paying payroll taxes?
Payroll tax responsibility is split across three buckets:
- Employee-paid amounts: federal income tax withholding, the employee share of Social Security tax, the employee share of Medicare tax, and, when applicable, Additional Medicare tax
- Employer-paid amounts: the employer share of Social Security tax, the employer share of Medicare tax, and FUTA tax
- State and local amounts: these depend on the location of the business and the worker
Even if you use payroll software or a payroll service, your business remains responsible for accurate withholding, depositing, and filing.
The main federal payroll taxes
Federal income tax withholding
Federal income tax is withheld from employee pay based on the employee’s Form W-4 and the IRS withholding tables in Publication 15-T. There is no single flat federal withholding rate for every employee.
The amount depends on factors such as:
- Filing status
- Other jobs or household income reported on Form W-4
- Dependents and credits claimed
- Extra withholding requested by the employee
For employers, the key point is simple: get a completed W-4 from each new employee and use it consistently in your payroll system.
Social Security tax
For 2026, the Social Security tax rate is 6.2% for the employee and 6.2% for the employer, for a total of 12.4% on taxable wages. The Social Security wage base limit is $184,500 per employee for 2026.
That means you withhold Social Security tax only until an employee’s year-to-date wages reach the wage base limit. After that point, Social Security tax stops for the rest of the year.
Medicare tax
The Medicare tax rate is 1.45% for the employee and 1.45% for the employer, for a total of 2.9%.
Unlike Social Security tax, Medicare tax has no wage base limit. It applies to all covered wages.
Additional Medicare tax
You must withhold an additional 0.9% Medicare tax from an employee’s wages once the employee’s wages paid in the calendar year exceed $200,000.
A few points matter here:
- The employer withholds the tax once wages pass $200,000 for that employee
- The withholding threshold is based on wages paid by your business, not the employee’s final tax liability
- The employee may owe more or less at tax time depending on their overall situation
FUTA tax
FUTA is the federal unemployment tax paid by the employer, not withheld from employee paychecks.
For 2026, the FUTA tax rate is 6.0% on the first $7,000 of each employee’s wages. In many cases, state unemployment taxes reduce the amount a business ultimately owes in federal unemployment tax, but the details depend on the state and the employer’s situation.
State payroll taxes can change the setup
Federal payroll tax rules are only part of the picture. Many states also require one or more of the following:
- State income tax withholding
- State unemployment insurance contributions
- Disability insurance contributions
- Paid family and medical leave contributions
- Local payroll or employment taxes
State rules vary widely, so your payroll setup should always include a review of the state where the employee works, not just where your business is headquartered.
How payroll tax deposits work
The IRS requires employers to deposit withheld employment taxes electronically. In general, those deposits include:
- Federal income tax withheld
- Employee Social Security tax
- Employee Medicare tax
- Employer Social Security tax
- Employer Medicare tax
- Additional Medicare tax withheld
The IRS uses two basic deposit schedules:
- Monthly deposit schedule: deposits are generally due by the 15th day of the following month
- Semiweekly deposit schedule: deposit timing depends on when wages were paid
Your deposit schedule is based on your lookback period, not on how often you run payroll.
There is also a next-day deposit rule. If you accumulate $100,000 or more in employment tax liability on any day, you generally must deposit by the next business day.
Most employers use the Electronic Federal Tax Payment System (EFTPS) or another IRS-approved electronic payment method to make deposits.
The federal forms you need
Form 941
Most employers file Form 941, Employer’s Quarterly Federal Tax Return, to report wages, federal income tax withheld, and Social Security and Medicare taxes.
The due dates are generally:
- April 30 for the first quarter
- July 31 for the second quarter
- October 31 for the third quarter
- January 31 for the fourth quarter
If you made all deposits on time and in full, you may have an additional 10 days to file in some cases.
Form 940
Form 940 is the annual federal unemployment tax return. It reports FUTA tax for the year and is generally due by January 31.
W-2 and W-3
At year-end, you must provide employees with Form W-2 and file Form W-3 with the Social Security Administration. These forms summarize wages and taxes for the calendar year.
A practical first-payroll checklist
Before you issue your first paycheck, make sure these items are in place:
- Obtain an EIN
- Register with the state tax agencies where you have employees
- Collect Form W-4 from every employee
- Complete Form I-9 verification for each worker as required
- Choose payroll software or a payroll provider
- Set up EFTPS or another approved federal payment method
- Determine your deposit schedule
- Confirm your state unemployment account number and filing cadence
- Build a payroll calendar for pay dates, deposit dates, and filing deadlines
- Decide who will review payroll before each run
A clean setup matters more than speed. Payroll errors often become tax errors.
Common payroll tax mistakes to avoid
Using old withholding tables
Federal income tax withholding changes as IRS forms and tables are updated. If you are doing payroll manually, use the current IRS guidance and tables.
Missing the deposit deadline
Depositing late can create penalties even when the tax amount itself is correct. A deposit calendar is not optional.
Confusing employee and employer taxes
Some taxes are withheld from wages, while others are paid by the company. Keep the two categories separate in your accounting system.
Forgetting state obligations
A business can be fully compliant federally and still miss state unemployment, withholding, or paid leave requirements.
Not reconciling payroll records
Your payroll records, Form 941 filings, W-2 totals, and accounting books should agree. Reconcile them regularly, not just at year-end.
When a payroll service is worth it
A payroll service can help if your business has:
- Multiple employees or contractors
- Workers in more than one state
- Recurring overtime, bonuses, or commissions
- Complex withholding questions
- Limited internal accounting staff
A service can reduce administrative burden, but it does not eliminate your responsibility to review the numbers and keep records.
Best practices for staying compliant
A strong payroll process usually includes:
- Running payroll on a fixed schedule
- Reviewing every new hire’s tax forms immediately
- Reconciling payroll each quarter
- Tracking state registrations separately from federal filings
- Keeping copies of deposits, filings, and employee forms in one place
- Reviewing IRS publication updates at the start of each year
The goal is not perfection in one payroll cycle. The goal is a system that is repeatable and easy to audit.
Final thoughts
Payroll taxes are one of the first recurring compliance duties new employers face, and they are also one of the easiest areas to mishandle if you rush setup. The good news is that the rules become much easier to manage once you know which taxes apply, how deposits work, and which forms are due each quarter and each year.
