How to Build an HR Budget: Seven Line Items for a Small Employer

An HR budget for a small employer has seven line items: payroll taxes and fees, benefits administration, recruiting, training and development, compliance and legal, HR technology, and outside HR support. Start from the hires you plan, add the fixed tax rates, then size each remaining line from last year’s actual spend. Review it quarterly against the headcount plan.

I am Mac Malbrough. I hold a J.D. and an MS-HRM, I am not an attorney, and I help small employers plan the cost of people. The company in the worked example is a hypothetical I made up to show the arithmetic. It is not a client or a benchmark.

Why do small employers rarely have an HR budget?

HR costs are scattered. Payroll taxes sit in one report, the health plan in another, a job board charge on a credit card, a training course in the owner’s expenses. Nobody adds them up, so nobody can answer the owner’s simple question: what does it cost us to employ people, and what are we getting for it?

That gap matters when a budget decision arrives. Should we hire two people or one? Replace a tool? Pay for a compliance review? Without a number, each decision is made by instinct. A one-page HR budget gives you a baseline and a way to show leadership what a hiring plan will cost before it is approved.

What are the seven line items?

1. Payroll taxes and fees: employer taxes, payroll provider charges, workers’ compensation premiums
2. Benefits: the employer share of health coverage, retirement match and any other benefits, plus administration charges
3. Recruiting: job board fees, recruiter fees, background checks, interview time and referral bonuses
4. Training and development: courses, certifications, conferences, required compliance training and paid learning time
5. Compliance and legal: audits, required postings and notices, legal review of policies and counsel for hard issues
6. HR technology: HR information system, applicant tracking, learning tools, e-signature and any AI tools
7. Outside HR support: fractional HR, consultants and any PEO or broker fees

What tax rates should you use for payroll?

Two groups of employer taxes apply to almost every small employer. Federal first: the IRS states that the Social Security rate is 6.2 percent for the employer and 6.2 percent for the employee, and the Medicare rate is 1.45 percent for each. The Social Security wage base for 2026 is $184,500, so most small company employees are below it and the employer share is 7.65 percent of wages.

California adds its own. The Employment Development Department lists the new employer unemployment insurance rate for 2027 at 3.4 percent, applied for two to three years until the employer’s own rate is calculated, plus an Employment Training Tax of 0.1 percent. Both apply to the first $7,000 of each employee’s wages in a year. A new-employer rate is a starting point. Your account’s notice from EDD controls, so use the rate on your notice.

Also include workers’ compensation premiums. They depend on your classification codes and payroll, so take the figure from your policy, not from a guess.

What does a worked example look like?

Here is a hypothetical. A California company has 15 employees and wages of $1,200,000 a year, all below the Social Security wage base.

• Federal employer payroll tax at 7.65 percent: $91,800
• California unemployment at 3.4 percent of the first $7,000 per employee: $3,570
• California Employment Training Tax at 0.1 percent of the same wages: $105

Those three lines total $95,475, which is about 8 percent of wages before workers’ compensation and any fees. The amount is not surprising. It is something nobody at the company had written down. Add the health plan invoices, a retirement match if you have one and the payroll provider’s fees, and the first line is complete.

For the people plan, add the hires. The Headcount and Hiring Forecast estimates plan-year cost for each hire including federal payroll tax and gives you a budget check, and the Salary Band and Pay Range Builder Workbook for California Employers sets the pay ranges the forecast should use.

How do you size recruiting and training?

Use your own history. For recruiting, add up last year’s costs per hire: job board fees, agency fees, background checks and the hours managers spent interviewing. If you do not know your cost per hire, calculate it with the formula in how to calculate HR metrics correctly. Then multiply by the hires in your plan and add the cost of replacing the people you expect to lose.

For training, start with required items: in California, supervisor and employee harassment prevention training is required for employers with five or more employees, so budget for it. Then add the development you want. Rather than a flat percentage of payroll, base the amount on needs. The training needs analysis workbook helps you decide which skills matter most and what each gap costs to close. To judge whether training changes behavior, the Training Evaluation Kit measures learning and application, not just completion.

What goes under compliance, technology and outside support?

Compliance is the line most likely to be underfunded until something goes wrong. Include a planned review each year: a wage and hour check, handbook updates and posting updates. The California Wage and Hour Self-Audit Workbook covers breaks, overtime, regular rate and final pay, which are the areas where mistakes are most expensive. My HR compliance check-up is a defined engagement if you want an outside review.

For technology, list every tool, the seats you pay for and the seats in use. The HR Tech Stack Audit finds overlap, gaps and unused seats before a renewal. My article on HR software cost for small business shows typical pricing structures.

For outside support, compare the options by what you get. Fractional HR cost in the Bay Area covers my own pricing logic. Include any broker or PEO fees, because they are often bundled into other charges.

How should you present and review the budget?

Present one page with the seven lines, last year’s actual spend, this year’s plan and a note explaining each change. Put the headcount plan next to it, because the biggest swings come from hiring. Review it quarterly: compare actual to plan, note which lines moved and why, and adjust the next quarter. Put the federal and state deadlines on a calendar so cash is available when payments are due, and the Federal Employer Deadline Calendar 2027 helps with the federal side.

One caution: this is a planning method, not tax or accounting advice. Confirm rates and rules with your payroll provider and your CPA.

How do you handle a mid-year change?

Plans break. A key person resigns, a contract ends or the company wins work that needs two more hires. Build a small contingency into the recruiting and outside support lines, and keep a note on the budget page of the assumptions behind each line, such as “two hires in the second quarter.” When an assumption changes, update the note and the number in the same sitting, and record the date. At the quarterly review, show the original plan, the revised plan and the reason. This keeps the owner’s trust, because the budget is a living document with a visible history and not a set of numbers that quietly drift.

Keep one more habit: record every HR purchase with its line number at the time you pay it. A tag on the invoice or a column in the expense report is enough. Reconstructing categories at year end is slow and error-prone, while tagging as you go makes the quarterly review a ten-minute task and leaves a clear trail for your accountant.

What should you do this week?

Open last year’s payroll report and your last three months of statements and list every cost that touches the seven lines. Total each line. You will find costs that were never classified as HR, and one or two lines you cannot fill from your records. Those blanks are your first tasks.

Then build the next year’s hiring plan in the Headcount and Hiring Forecast and carry the totals to the budget page. If you want help sizing the lines or deciding what to outsource, book a free consult through my HR services for small businesses.
