When Is the Best Time to Switch Accountants for Your Law Firm?

Executive Summary & Key Points

The Big Picture

The best time for switching accountants is usually before year-end or before tax season, but law firms can switch accountants at any point during the year. The right timing depends on your books, upcoming tax deadlines, and whether your current accountant is still meeting your firm’s needs.

Year-end or the start of a new year can create a clean transition point. But waiting until January is not always the best choice. If your current accountant is causing delays, missing tax planning opportunities, or giving you little insight into your firm’s finances, it may make sense to switch sooner.

The goal is not to find a perfect date. It is to make the transition with a clear plan.

The Cheat Sheet

• You can switch accountants at any time during the year.
• Late fall or year-end can provide a natural transition point for many law firms.
• Avoid waiting until a major tax deadline if you already know you want to make a change.
• Make sure bookkeeping, payroll, tax records, and trust accounting information are transferred correctly.
• Choose a new accountant based on the support your firm needs going forward, not just what went wrong with the old relationship.

Why Timing Matters When Switching Accountants for Your Law Firm

Running a law firm involves more than sending invoices and paying expenses. Your financial systems may include operating accounts, trust accounts, payroll, owner compensation, estimated taxes, case costs, credit cards, loans, and other moving pieces.

That can make switching accountants feel overwhelming.

Law firm owners may worry that changing accountants will create problems with tax filings, financial reports, or trust account records. As a result, they sometimes stay with an accountant who is no longer a good fit simply because changing feels difficult.

But staying in the wrong accounting relationship can have a cost.

You may be missing proactive tax planning. Your books may not give you a clear picture of cash flow. Reports may arrive too late to help you make decisions. Trust accounting problems may remain unnoticed. You may also spend too much time trying to get basic answers.

The right time to switch is often before those problems become bigger.

A well-planned transition should protect the financial history of your firm while giving your new accountant the information needed to move forward.

Is Year-End the Best Time to Switch Accountants?

Why It Matters

Year-end is one of the first times law firm owners think about switching accountants. It feels natural because one financial year is ending and another is beginning.

For many firms, this can be an excellent time to make the switch.

How It Works

A year-end transition can provide a clean cutoff between your old accountant and your new one. For example:

• Your current accountant may finish bookkeeping within a set month.
• Your new accountant can review the books before the new year begins.
• Payroll and owner compensation can be reviewed.
• Tax planning can be discussed before important decisions are finalized.
• Outstanding bookkeeping issues can be identified.
• The new accounting team can prepare for the upcoming tax season.

However, December 31 is not a magic date.

Waiting until the last few days of December can actually make the transition harder. There may be year-end payroll filings, tax planning decisions, bookkeeping cleanup, and other deadlines happening at the same time.

If you are considering switching accountants around year-end, start the conversation earlier.

CPA Pro Tip

Do not wait until December 30 to tell your new accountant that you want them to take over January 1. Give both teams enough time to transfer records, review the books, identify missing information, and assign responsibilities.

Should You Switch Accountants Before Tax Season?

Why It Matters

Many business owners realize they are unhappy with their accountant during tax season. Unfortunately, that can also be one of the busiest times to make a change.

The better approach is to identify problems before tax season begins.

How It Works

Switching accountants before tax season can give your new accountant time to understand your firm before a return is due.

They may need to review:

• Prior-year tax returns
• Current financial statements
• QuickBooks Online
• Payroll reports
• Estimated tax payments
• Fixed assets
• Owner compensation
• Business entity structure
• Loans and financing
• Retirement contributions
• Prior tax planning recommendations

This review matters because a tax return is based on financial activity that already happened.

Your accountant cannot go back in time and change every decision after December 31.

That is why tax planning should happen throughout the year, not only when your return is being prepared. Our guide to Tax Strategy Planning for Law Firm Owners: How to Reduce Taxes All Year Long explains why proactive planning gives law firm owners more opportunities to make tax decisions before important deadlines pass.

If you already know your current accountant is not providing the level of planning your law firm needs, waiting until tax season may mean losing another year of opportunities.

CPA Pro Tip

Think about tax planning and tax preparation as two different services. Tax preparation reports what already happened. Tax planning looks ahead and helps you make informed decisions before deadlines pass.

Can You Switch Accountants in the Middle of the Year?

Why It Matters

Yes. You do not have to wait until January 1 to switch accountants.

In fact, waiting can sometimes create more problems than switching midyear.

How It Works

A midyear change can work well when responsibilities are clearly divided.

Your new accountant may establish a cutoff date and determine who is responsible for each task before and after that date.

For example, the transition may include:

• Confirming the last month closed by your former accountant
• Reviewing year-to-date financial reports
• Reconciling bank and credit card accounts
• Reviewing payroll records
• Confirming estimated tax payments
• Reviewing accounts receivable and accounts payable
• Checking outstanding loans and liabilities
• Reviewing trust account records when applicable
• Confirming access to QuickBooks Online and other financial systems

The goal is continuity.

You do not want January through June handled one way and July through December handled another way without anyone checking whether the two periods connect correctly.

Your new accountant should understand what happened earlier in the year before advising you about what should happen next.

CPA Pro Tip

A midyear switch can actually be helpful for tax planning. There may still be time to make changes before year-end instead of discovering problems when the tax return is already being prepared.

When Should a Law Firm Switch Accountants Immediately?

Why It Matters

Timing matters, but some problems are more important than timing.

If your financial systems are becoming less reliable, waiting for a convenient date may not be worth it.

How It Works

Consider switching accountants sooner if you regularly experience problems such as:

• Financial reports that are consistently late
• Books that are months behind
• Questions that go unanswered
• Surprise tax bills with little warning
• No proactive tax planning
• Little or no discussion about cash flow
• Unclear financial reports
• Repeated bookkeeping errors
• No regular advisory conversations
• Poor communication between bookkeeping and tax professionals
• Trust accounting concerns
• Lack of understanding of law firm finances

One isolated mistake does not always mean you need a new accountant. Patterns matter.

If you repeatedly have to chase down reports, ask for updates, or discover problems after it is too late to fix them, your accounting relationship may no longer support your firm’s needs.

That becomes especially important as your law firm grows.

The financial support that worked when your firm was smaller may not be enough once you have employees, more clients, larger cases, higher expenses, and more revenue.

CPA Pro Tip

Do not judge an accountant only by whether your tax return was filed on time. Ask whether your financial information is helping you make better decisions throughout the year.

What Should You Transfer When Switching Accountants?

Why It Matters

A successful transition depends on information.

Your new accountant needs enough historical data to understand your firm’s financial position and continue the work without creating gaps.

How It Works

Your transition checklist may include:

• Prior business tax returns
• Prior personal tax returns when relevant to planning
• Year-to-date profit and loss statement
• Balance sheet
• General ledger
• Bank statements
• Credit card statements
• Payroll records
• Estimated tax payment history
• Fixed asset schedules
• Loan documents
• Depreciation schedules
• Prior adjusting journal entries
• QuickBooks Online access
• Clio access when appropriate
• Trust account records
• Prior reconciliation reports
• Client trust ledgers
• Accounts receivable information
• Accounts payable information
• Business formation documents
• IRS and state correspondence

For law firms, trust accounting deserves extra attention.

Changing accountants should not break the history of your trust records. If your firm maintains an IOLTA, COLTAF, or similar trust account, make sure the transition includes the records needed to support reconciliations and individual client balances.

The new accountant should understand where the old accountant stopped and where the new team’s responsibility begins.

CPA Pro Tip

Keep copies of important records even if your former accountant maintains them. Your firm should have access to its own financial history.

How Do You Choose the Right Accountant for Your Law Firm?

Why It Matters

Switching accountants only helps if the new relationship solves the problems that caused you to leave the old one.

Do not focus only on finding someone who can prepare your tax return. Look at the full financial picture.

How It Works

Before choosing a new accountant, ask what your law firm actually needs.

That may include:

• Monthly bookkeeping
• Monthly financial reporting
• Trust accounting support
• Tax preparation
• Proactive tax planning
• Estimated tax calculations
• Payroll coordination
• Cash flow guidance
• Entity planning
• Quarterly advisory meetings
• Financial technology integration
• Support as the firm grows

You should also ask how often you will hear from your accountant.

If your goal is proactive financial management, one meeting during tax season is probably not enough.

Regular reporting and advisory conversations can help you identify problems earlier and make decisions based on current numbers.

The IRS also recommends considering a tax professional’s qualifications and whether that professional will be available throughout the year if questions come up after filing season. You can review the IRS guidance for selecting a tax professional as a small business taxpayer.

Industry experience also matters.

Law firms have financial issues that many other businesses do not have. Trust accounting is one example. Contingency fees, case costs, retainers, uneven revenue, owner compensation, and collections can also affect how a law firm’s finances should be managed.

An accountant who understands those issues can spend less time learning your business and more time helping you improve it.

CPA Pro Tip

Ask a potential accountant what happens after the tax return is filed. Their answer can tell you a lot about whether they provide year-round advisory support or mainly focus on tax compliance.

Commonly Missed Items When Switching Accountants

Switching accountants involves more than transferring QuickBooks and last year’s tax return. Smaller details can create bigger problems later if no one takes responsibility for them.

One commonly missed item is estimated tax payments. Your new accountant should know what you have already paid during the year and what may still be due. Without that information, tax projections can be inaccurate.

Another is payroll and owner compensation. If your law firm operates as an S corporation, compensation decisions may affect both payroll and tax planning. These items should not be reviewed in isolation.

You should also review access permissions. Your former accountant may have access to QuickBooks Online, payroll platforms, banking information, document portals, or other systems. Determine which access should remain and which should be removed after the transition is complete.

For law firms, trust accounting history can be particularly important. Make sure reconciliations, client ledgers, bank statements, and supporting records remain available.

Finally, do not overlook unfinished projects.

Your former accountant may have been working on amended returns, bookkeeping cleanup, notices, payroll corrections, or tax elections. Make a list of open items and clearly establish who will finish each one.

A good transition is not just about moving files. It is about transferring responsibility.

Frequently Asked Questions

The Right Time for Switching Accountants Is Before Financial Problems Hold Back Your Firm

Switching accountants should not be based on guesswork or an arbitrary date on the calendar.

The right time depends on what your firm needs, what deadlines are ahead, and whether your current financial systems are giving you the information and guidance needed to run the business.

Year-end can be a convenient transition point. So can the months before tax season. But if your books are consistently late, tax planning is reactive, communication is poor, or you do not trust your financial reports, waiting another six months simply for a cleaner date may not make sense.

Strong financial systems should give law firm owners clarity throughout the year.

You should know how your firm is performing, understand your cash position, stay ahead of tax obligations, and have reliable financial information available when making growth decisions.

Tax strategy should be part of that system.

As your law firm grows, your accounting needs often become more complex. Better planning can help you understand the tax impact of compensation, hiring, investments, entity structure, and other major decisions before you make them.

The best accounting relationship is not just about closing last year’s books. It should help you plan for what comes next.
