Engineering & Professional Services Firms: Integrating Benefits with Payroll (2026)
Benefits integration for engineering firms means every benefit deduction and every employer contribution flows through payroll with the right pre-tax or post-tax treatment, the ACA count runs from payroll hours, and the engineering firm items cited here, IRS About Form 8974 and IRS: Independent contractor (self-employed) or employee?. BEG: $45 per employee per month inside the payroll software you already use, live in 3 to 5 days.
Benefit rules that reach engineering firms
Employers use Form 8974 to determine the qualified small business payroll tax credit for increasing research activities that can be claimed on the employment tax return; related forms listed by the IRS include Forms 941, 943, 944 and 6765.
Firms that engage individual engineers or drafters as contractors must apply the IRS common law rules on behavioral control, financial control and type of relationship; if status is unclear, either the business or the worker can file Form SS-8 for an IRS determination, which may take at least six months.
What integration actually does
Section 125 pre-tax premiums come off before FICA and income tax; 401(k) deferrals come off before income tax only; Roth and most voluntary deductions are post-tax. Employer contributions are recorded per employee for the 401(k) census and Form 5500. Payroll hours feed the ACA full-time and full-time-equivalent count, and at 50 or more the offer of coverage is documented on Form 1095-C from that same data. For engineering firms with prevailing wage for government projects, the benefit base has to be defined per plan document, because the plan decides whether that pay counts as compensation.

Frequently Asked Questions
Benefits and engineering firm payroll: IRS About Form 8974
Employers use Form 8974 to determine the qualified small business payroll tax credit for increasing research activities that can be claimed on the employment tax return; related forms listed by the IRS include Forms 941, 943, 944 and 6765.
Benefits and engineering firm payroll: IRS: Independent contractor (self-employed) or employee?
Firms that engage individual engineers or drafters as contractors must apply the IRS common law rules on behavioral control, financial control and type of relationship; if status is unclear, either the business or the worker can file Form SS-8 for an IRS determination, which may take at least six months.
Does prevailing wage for government projects count as compensation for a 401(k) match?
Only if the plan document says so. Plan compensation definitions vary, and payroll has to apply the definition the plan uses, not the one that seems natural. A mismatch is one of the most common plan failures found on audit.
What does managed payroll cost for an engineering firm?
$45 per employee per month, all-inclusive, inside the payroll software you already use, with no monthly minimum. Prevailing wage for government projects, billable hour payroll allocation and PE license classification are configured at setup, not billed as add-ons.
