Managing law firm payroll: Best practices for legal employers

Published By:

When you first started, your firm’s payroll was simple. It might have involved just you and a part-time paralegal with a few predictable expenses. You had no complex bonus structure, no partner draws to split, no multi-state taxes to keep track of — just you working hard and taking home whatever was left.

Key takeaways

  • Proper employee classification is critical which means partners, associates, and contractors have different tax and compliance requirements that must be handled correctly to avoid IRS scrutiny
  • Multi-state operations require specialized payroll management so firms working across jurisdictions need to register in each state and comply with varying tax rates and labor laws.
  • Trust account funds must never be used for payroll meaning mixing client funds with payroll expenses can lead to ethics violations and potential disbarment

But as you built up your reputation, your team began to grow. You hired associates, entered into new jurisdictions, and started offering bonuses tied to billable hours and other compensation models. Your payroll got bigger and more complicated. Now, managing it feels like a full-time job and you’re on the lookout for guidance on keeping it all together.

 

In this primer, we cover what growing law firms need to keep in mind, payroll practices to help you keep up with compliance, and build a system that supports your staff and your continuing growth.

Classifying legal roles correctly: partners, associates, and contractors

Oftentimes, law firms have employees who fill a mix of roles, each with a different compensation model and compliance requirements. So, one of the first steps to take in effective payroll management is accurate classification.

 

Equity and non-equity partners

Equity partners receive a share of your firm’s profits, not a traditional salary. You should handle their compensation through draws or distributions, meaning they shouldn’t be on payroll. In other words, it makes a lot of sense to treat them as self-employed for tax purposes, as the IRS doesn’t treat partners as employees.

 

Even if their title indicates “partner,” non-equity partners receive a salary instead of partner distributions and are classified as W-2 employees.

 

Salaried associates and paralegals

Associates and paralegals are standard W-2 employees, but their overtime eligibility depends on how they are classified under the Fair Labor Standards Act (FLSA). Associates are FLSA-exempt professionals, meaning they aren’t entitled to overtime pay, even when they work long hours. Paralegals are usually non-exempt and are entitled to overtime if they work late to meet a deadline.

 

1099 contract attorneys and consultants

If you bring in contract attorneys or consultants for short-term projects, they may qualify as independent contractors if they control how and when they work and offer similar services to other clients. If not, treat them as employees, since misclassifying contractors can draw scrutiny from auditors and tax authorities.

 

Support staff and administrative roles

Most administrative roles, such as receptionists and bookkeepers, are hourly W-2 employees. Some may qualify as exempt employees if they have supervisory responsibilities or meet exemption criteria, but most don’t. Track hours worked to stay compliant and simplify your payroll processing.

Tracking time and allocating bonuses by billable hours

Once you’ve classified legal roles in your firm, connect time tracking to payroll. Use law firm payroll software that pulls in billable hours automatically to simplify bonus and payroll tax calculations.

 

Set clear, transparent criteria for performance-based bonuses, so team members know exactly how their efforts translate to compensation. Such clarity also helps you determine payroll costs related to incentives.

How to manage multi-state payroll for attorneys working across jurisdictions

If you have expanded your operation across state lines, law firm payroll management gets more complex:

  • Different states have different income tax rates.
  • Labor laws and overtime rules can vary by state.
  • You need to register as an employer in each state.
  • Some cities have unique payroll taxes.

 

Register in every state where your employees work, and track where the work happens so you can apply the right income tax and follow local labor laws. Use payroll solutions for law firms that support multi-state compliance, and stay current with changing state regulations to avoid stumbling into noncompliance.

Compliance tips for managing trust accounts and IOLTA funds

Ethical management of clients’ money is a major responsibility for lawyers — important enough that the penalties for violations can even include disbarment. To safeguard your clients’ interests and avoid disciplinary action you’ll need to carefully manage trust accounts and Interest on Lawyers’ Trust Accounts (IOLTA) funds. However, the process can be challenging because it involves maintaining detailed ledgers and reconciliations.

 

To remain compliant:

  1. Use a separate trust account for client and third-party funds.
  2. Never use a trust account to cover payroll. This can constitute misappropriation.
  3. Set up internal controls, such as dual approval or restricted access, to prevent misallocation.
  4. Review trust accounts regularly to catch any errors early.

Key steps to reporting and audit readiness for law firms

Law firms face strict payroll reporting obligations that require precision and a clear audit trail. To be audit-ready and meet reporting requirements:

 

Issue W-2s and 1099s accurately and on time

Send accurate W-2s to employees and 1099s to contractors before deadlines to avoid penalties.

 

Align payroll records with legal standards

Verify that your payroll records match up with trust accounting practices and bar association expectations. This is especially important when documenting and approving compensation.

 

Stay current on quarterly and state filings

Federal forms, such as the 941, must be filed quarterly, while states may require additional reports for income tax withholding and unemployment insurance contributions.

 

Maintain transparent and consistent documentation

Document every bonus, partner draw, pay adjustment, or other payroll activity to protect your firm during tax audits or professional reviews.

Avoiding payroll compliance risks in legal settings

There are common payroll management errors to avoid and protect your firm from costly fines and ethics violations.

 

Payroll error What can happen Safeguards against FLSA or IRS penalties
Misclassifying roles Trigger IRS and FLSA scrutiny Classify partners and employees by roles, not titles
Inaccurate time and overtime tracking Missed wages, FLSA/state violations Use reliable payroll services for law firms and choose a time-tracking system that can be linked to payroll
Omitting bonuses or fringe benefits Skewed payroll taxes and audit flags Include all compensation types in payroll calculations
Missing tax filing or withholding deadlines IRS/state penalties and interest Automate tax filing where possible
Incomplete or inconsistent payroll records Failed audits open legal risks Maintain organized, up-to-date records for at least 3-4 years, depending on regulations in your region and field

 

These potential pitfalls underscore the importance of payroll precision in legal practice. Between managing 1099 contractors, multi-state compliance, and trust account rules, it can be complex. The good news? With the right systems and processes in place, you can streamline these operations and minimize risk.
