How to bridge the experience gap in accounting firms

Accounting firms are running into a math problem that has nothing to do with tax code. Accountants are leaving the profession faster than new ones are coming in, even as client demand keeps climbing. Research from the Thomson Reuters Institute and the AICPA/NASBA Trends Report points to the same cause: the pipeline of accounting graduates has shrunk for over a decade, while the workload on remaining staff keeps growing. 

That imbalance creates a real experience gap:  

• Senior staff hold the institutional knowledge but don’t have the hours to transfer it 
• New hires are capable but can’t access that knowledge fast enough on their own 

Firms that figure out how to bridge the experience gap in accounting firms (without overworking the people responsible for training) are the ones that will keep their client base intact.

Why the experience gap is getting worse 

There are a few key data points that explain why this problem has become urgent: 

• Senior accountant, staff accountant, and tax accountant roles rank among the hardest positions to fill, according to a 2026 survey of finance and accounting leaders reported by Accounting Today. 
• The average number of open accounting and finance roles per company jumped to 17 in 2026, up from just two in 2024. 
• Unemployment among accounting professionals has hovered between 1% and 2%, according to Robert Half, meaning nearly everyone qualified is already working somewhere. 
• 20% of mid-sized firms name the talent shortage as the single biggest obstacle to hitting their goals, per the Thomson Reuters Institute’s State of Tax Professionals report.

The retirement timeline doesn’t help 

Many firms lack the budget and recruiting power to hire their way out of this. A large share of the accounting workforce is approaching retirement, and every senior accountant who leaves takes years of client history and judgment with them. Replacing that knowledge takes structured, repeatable training that doesn’t depend entirely on one partner’s calendar. 

How to train your junior staff without slowing down the rest of the firm 

Most firms already know they need better onboarding. The roadblock? How to train their junior staff when the people qualified to teach them are already working at capacity. Three shifts tend to make the biggest difference: 

• Give new hires a way to self-serve research: Junior staff shouldn’t have to interrupt a senior accountant every time they hit an unfamiliar filing requirement. A searchable, authoritative research platform lets them find and verify the answer on their own. 
• Standardize how work gets reviewed: When each senior accountant reviews work differently, junior staff spend more time guessing at preferences than learning the material. 
• Make institutional knowledge visible, not just verbal: If a firm’s know-how lives only in senior accountants’ heads, it disappears when they leave. Capturing it in a shared format means it survives staff turnover. 

Firms that build these habits early on are poised for better retention rates. New hires feel equipped tend to stay longer, and senior staff spend less time repeating the same explanations. 

Where CoCounsel Tax and CoCounsel Audit & Accounting fit in 

Here’s the layer where the right technology can make all the difference. Thomson Reuters CoCounsel Tax and CoCounsel Audit & Accounting provide the knowledge base and authority to close the distance between what junior staff know and what senior staff need them to know. 

What CoCounsel Tax does for research and training 

With CoCounsel Tax, access to federal, state, and cross-border tax content, IRS guidance, and internal firm documentation is just a search away, consolidated into one workspace for your entire tax team. 

• Answers are citation-backed, so staff members can verify the reasoning instead of taking it on faith. 
• Guided workflows walk less experienced preparers through multistep tasks the same way every time, keeping quality consistent across the team. 
• Research that used to take hours can be completed in minutes, freeing senior staff for review and advisory engagements instead of repeat lookups. 

What CoCounsel Audit & Accounting does for engagement teams 

CoCounsel Audit & Accounting applies the same approach to audit work, drawing on FASB, GASB, AICPA, and IFRS content alongside a firm’s own engagement files. 

• Get precise, cited answers to technical accounting questions instead of waiting on a manager’s availability. 
• Summarize client documents and flag key terms in agreements like leases and revenue contracts. 
• Produce documentation that holds up to review the first time, reducing the back-and-forth that usually falls on senior staff.

How bridging the experience gap impacts client service 

When junior staff can find trustworthy answers on their own, senior accountants field fewer interruptions and get their focus back. Clients feel the difference too: research that used to take days can turn around the same day, regardless of which staff member is available. 

Firms that treat this as a training and retention strategy, not just a productivity upgrade, see the clearest results. Junior staff who can move quickly and confidently are more likely to stay through the years it takes to become senior staff themselves, which is ultimately how firms close the experience gap for good. 

How to create cohesion between your junior and senior tax staff 

If your firm is asking how to bridge the experience gap in accounting firms and how to train your junior staff more efficiently at the same time, the starting point is the same: give every team member access to the same authoritative research and a consistent way to apply it.
