Labor burden is the cost that rides on top of the wages you pay a crew: payroll taxes, unemployment insurance, and leave programs. State and federal rules set many of those costs, and the rules change. If your crew includes workers in Minnesota or Maryland, or you might claim the federal paid leave credit, a flat burden percentage copied from last year's bid can drift away from what you actually pay.
Key takeaways
- Pull the Minnesota unemployment tax rate for the bid year from your payroll provider, and check it against the statute.
- Put the Minnesota quarterly due date on the calendar. It runs from the calendar quarter, not from the job.
- Count every Maryland employee, including part time, seasonal and temporary workers, and workers under 18.
- Show the federal paid leave credit as a separate item until your tax preparer confirms it applies.
- At job close, reconcile estimated labor against actual wages, and carry the gap into the next bid.
This post covers three payroll rules that affect pricing, then the federal credit, a way to structure the burden line, and a short checklist for your next estimate. Treat it as a starting point, not tax advice. Confirm the details with your accountant or payroll provider, and treat the official pages linked in the text as the source of record.
Minnesota unemployment taxes are due by the end of the month after each quarter
Minnesota's unemployment tax statute sets the timing. It says the taxes "must be paid to the trust fund and must be received by the department on or before the last day of the month following the end of the calendar quarter" ( Minnesota Revisor of Statutes, Sec. 268.051).
The deadline runs from the calendar quarter, not from the job. A quarter that ends in September has its tax due by the end of October. The clock follows the calendar rather than your project schedule, so a job that runs across a quarter-end can create payments in two different months.
Consider a common case. A crew starts a project in late summer and finishes in early fall. Wages for the first weeks fall in one quarter, and the rest fall in the next. If the job-cost report only shows totals by project, you cannot easily see which part of the tax belongs to which quarter. Splitting labor by calendar quarter from the start avoids that problem when it is time to reconcile.
For estimators, the practical issue is cash flow. If your model assumes labor taxes leave the account when the invoice goes out, the Minnesota schedule may put the payment earlier or later than you planned. Put the quarterly due date on the company calendar, and make sure your job-cost reports can total wages by calendar quarter. That way the tax you pay can be checked against what you recorded. For more on how this tax fits into crew costs, see Minnesota unemployment insurance in crew burden.
Minnesota rates depend on your own history and on actual wages
The same statute explains how the rate is built. For each calendar year, the commissioner computes the tax rate of each taxpaying employer that qualifies for an experience rating "by adding the base tax rate to the employer's experience rating along with assigning any appropriate additional assessment under paragraph (c)."
Three things follow for a bid. First, your rate is not one fixed state number. It starts from a base tax rate, adds your own experience rating, and can include an additional assessment where one applies. A percentage copied from a competitor, or from a job two years ago, may not match the rate that applies to your firm in the year you are bidding.
Second, the statute says which wages count: "Actual wages paid must be used in the calculation and estimates may not be used." A bid can use planned payroll, because bids have to look forward. The tax calculation, though, runs on wages actually paid. When a job closes, compare the labor you estimated with the wages actually paid, and record the gap. That is how the next bid starts from real numbers instead of a guess.
Third, the statute limits one kind of reduction. Its paragraph (c) says: "The unemployment tax reduction under this subdivision does not apply to employers that were assigned a tax rate equal to the maximum experience rating plus the applicable base tax rate for the year." If your firm has been assigned that maximum rate for the year, do not price in an unemployment tax reduction the statute says does not apply to you. If you are unsure where your account sits, ask your payroll provider which rate is assigned for the year and check it against the statute before you finalize the burden line.
A short rate note in the bid file helps here. Record the rate for the year, where it came from, and the date you pulled it. When someone asks in six months why the burden line moved, the note answers the question without a search through old email.
Maryland counts every employee toward the leave threshold
Maryland's Healthy Working Families Act includes a sick and safe leave requirement with an employer-size threshold. The state labor department's FAQ on the law explains who counts. It says: "All employees of the employer working in Maryland will be considered in determining the 15 employee threshold, including part time, seasonal and temporary employees" ( Maryland Department of Labor FAQ).
A contractor may count only full-time, year-round staff and assume a seasonal crew sits outside the count. The FAQ says it does not. Count every employee working in Maryland before you decide which obligations apply to the company. Seasonal and temporary hands belong in that headcount just as much as the permanent crew.
A practical way to do this is to pull a list from payroll that covers every person who worked in Maryland during the period, not only the people on the current roster. Include anyone who worked a single shift. Then compare that list with the threshold before the bid goes out, not after the job starts. For how leave costs enter a crew rate, see sick leave accrual rules for labor burden.
Younger workers are counted too. The FAQ says: "Although an employer is not required to provide sick and safe leave for employees under the age of 18, the employer must include them in the threshold determination." For a summer crew with workers under 18, that means they go into the headcount even though the employer is not required to provide them this leave.
The FAQ also covers union contracts. Extensions, options and renewals are not covered. If a crew works under a union contract, check the signing date and the original term rather than assuming the answer either way.
The FAQ also gives the law's history. It says that "as drafted, the bill provided that the law became effective January 1, 2018," and that "when the General Assembly came back into session in January of 2018, it voted to override the Governor's veto." Confirm which effective date applies to a current bid on the official page before you rely on it.
The table below sums up the rules from this section and the Minnesota statute in one place.
Illustrative example: counting a seasonal crew
Under the FAQ's rule, the seasonal hands count, so the headcount is 15, and that is the number to compare with the threshold. These figures are illustrative only.
The federal paid leave credit needs its own line
The IRS small business tax guide, Publication 334 for 2025, lists the "Employer credit for paid family and medical leave (Form 8994)" among its topics ( IRS Publication 334). That tells you where to look. Whether your firm qualifies depends on the facts of your leave program and on what your tax preparer confirms.
For pricing, keep the credit off the base crew burden line. A credit reduces the tax you owe. It is not a wage cost, and mixing it into labor burden makes the bid harder to check. Show it as a separate item on the estimate worksheet, marked as pending confirmation. Net it only after your preparer signs off. If the credit does not end up applying, the bid still holds, and nobody has to revise the number after the job starts.
Building the burden line around these rules
A burden line that holds up has layers, and each layer has a source. Start with base wages for each classification on the crew, not an average across the whole company. Add payroll taxes and unemployment insurance by state, using the rate for the year you are bidding and the wage basis described above. For the payroll tax layer, see employer FICA rates to add to labor burden. Then add any leave costs that apply to the crew, based on the headcount rules for each state. Finally, show the federal credit separately, as described in the previous section.
The table below shows where each layer's inputs come from, so the person checking the estimate knows where to look.
Label each layer with the document it came from and the date you pulled it. Rules change, and an estimate that cites its sources and dates is easy to re-check when a bid sits for months or a job is re-priced.
Set review triggers. Re-check the burden line when a crew moves between states, when the Maryland headcount approaches the threshold, when a calendar quarter closes, and when the rate assigned to your account changes. These are the points where the rules above are most likely to change the number.
Explaining the burden line to clients
Clients often see a single burden percentage and ask why it is higher or lower than another bid. A short breakdown answers most of those questions. Show the base wages, then the payroll taxes and unemployment insurance as state-driven items, then leave costs as a separate line. When a figure depends on the calendar or on headcount, say so in plain words, such as "this rate applies for the year of the bid" or "this changes if Maryland headcount changes."
Be careful with the federal credit in client conversations. Describe it as a possible item under review, not as a discount you have already earned. If the client is sensitive to price, you can offer to re-run the estimate once the tax preparer has confirmed the item. That keeps the bid honest and avoids a surprise later.
Clients also tend to trust a bid more when they can see what would change it. Naming the triggers, such as a crew moving states or a quarter closing mid-project, shows that the number is built on rules rather than a padded guess.
Common mistakes to avoid
The first mistake is pricing the burden from last year's bid. The rate for a calendar year is set for that year, so a bid built from an old figure can carry the wrong rate even when the wages are right. Pull the rate for the year you are bidding and note where it came from.
The second mistake is leaving people off a Maryland headcount. The FAQ counts every employee working in the state, so a firm that leaves out seasonal or youth workers may undercount before the bid is written. The count then drives which leave obligations get priced, so an undercount can leave a real cost out of the burden line entirely.
The third mistake is using estimated payroll as the final tax basis. A bid that never gets reconciled to actual wages will keep repeating the same error on the next job.
The fourth mistake is netting the federal paid leave credit into the crew burden before anyone has confirmed it applies. That makes the burden look lower than the firm can support, and it removes the easy fix of showing the item as pending.
The fifth mistake is ignoring the calendar. A quarterly deadline that falls in the middle of a job can strain cash flow even when the bid was correct. Build the due dates into your cash plan from the start.
Checklist for your next crew estimate
- Record which state each worker is based in or works in, and whether any worker is in both.
- For Minnesota, confirm the unemployment tax rate for the year with your payroll provider, and check it against the statute.
- For Minnesota, put the quarterly due date on the calendar, and confirm your job-cost reports can total wages by calendar quarter.
- For Minnesota, do not assume a reduction if your firm is at the maximum rate for the year.
- For Maryland, count every employee working in the state, and include workers under 18 in the headcount even though they are not owed this leave.
- For Maryland union crews, check the signing date and original term of the contract.
- At job close, reconcile estimated labor against actual wages, and feed the gap into the next bid.
Final word
Labor burden is easy to underprice when the rules differ by state and the numbers move through the year. The Minnesota quarterly deadline, the Minnesota rate and wage basis, and Maryland's employee count are a good place to start checking your burden line. Verify each one against the official source, keep the federal credit separate until it is confirmed, and the burden line will be easier to defend when the job closes.
Your next step: before you finalize your next estimate, record the Minnesota rate for the bid year, where it came from, and the date you pulled it.
Frequently asked questions
When is Minnesota unemployment tax due?
Minnesota unemployment taxes must be received by the department on or before the last day of the month following the end of each calendar quarter.
Does a seasonal crew count toward Maryland's threshold?
Yes. The Maryland Department of Labor FAQ says all employees working in Maryland count toward the 15 employee threshold, including part time, seasonal and temporary employees.
Does the federal paid leave credit go in the crew burden line?
No. Keep it off the base crew burden line, and show it as a separate item marked pending until your tax preparer confirms that it applies.
