The future of accounting firms between now and 2030 is already visible in published rules and official data. Demand for accountants keeps growing slowly, the route to a CPA license is changing state by state, tax filing is moving onto newer electronic channels, e-invoicing mandates are arriving abroad, and the IRS has told practitioners how AI use fits within Circular 230.
Apart from the BLS employment projection, each of these changes is already published with a date attached. This guide sets out what each shift means for the future of accounting firms, how a firm might phase its operating model to 2030, and what has to be in place for that model to hold up.
Most writing about the accounting firm of 2030 relies on vendor surveys and predictions. The table below uses only official sources, so a partner group can plan against dated, checkable facts.
| Change | Source | Date or horizon | What it affects |
|---|---|---|---|
| Steady demand, openings driven by replacement | BLS Occupational Outlook Handbook | Projection period 2025 to 2035 | Hiring plans and capacity |
| An additional CPA licensure pathway | AICPA and NASBA model legislation | Approved 14 May 2025; state adoption ongoing | Entry-level pipeline and review capacity |
| FIRE retired; information returns move to IRIS | IRS news release IR-2026-99 | FIRE closes 19 November 2026 | Information return workflows |
| Mandatory e-invoicing for UK VAT invoices | UK government consultation response | From 2029 | Firms with UK clients or subsidiaries |
| Responsible AI guidance for tax practice | IRS OPR Issue Number 2026-19 | Published 24 June 2026 | Review, fees, vendor vetting |
The sections that follow take each change in turn. For the short-term view of what these shifts mean for outsourcing scopes this filing season, see our companion guide to outsourced accounting trends for 2026.
The BLS Occupational Outlook Handbook projects that employment of accountants and auditors will grow 5 percent from 2025 to 2035. It expects about 115,300 openings each year on average over the decade, against about 1.6 million jobs held in 2025. The median annual wage was $83,680 in May 2025.
Multiplying the BLS annual average by ten years gives roughly 1.15 million openings across the projection period. BLS says many of those openings come from the need to replace workers who move to other occupations or leave the labor force. For a firm, that means the hiring problem of the next five years is mostly a refill problem. Each retirement or resignation opens a seat that has to be filled while client work continues.
That pattern favors firms that plan capacity as a standing structure. A firm that already has documented workflows and a trained outsourced team can absorb an empty seat without a busy-season scramble. Firms that rely entirely on local hiring will keep competing for the same candidates at the same time of year.
On 14 May 2025, the AICPA and NASBA boards approved model legislation for an additional licensure pathway. It requires a baccalaureate degree with an accounting concentration, two years of experience and passage of the Uniform CPA Examination. The same package moves mobility from a state-based model to an individual-based practice privilege, so a CPA can practice across state lines with one license.
States must enact legislation or adopt rules before candidates can use the new route. The AICPA release reported 14 states at that date, and NASBA keeps a jurisdiction list that it updates as more states act. Firms should check the rules in each state where their staff will seek licensure.
Take a student who finishes a 120-credit accounting degree in May 2026 and passes the CPA Exam during the period shown. The table compares the earliest licensure date on each route, assuming continuous full-time study and work.
| Step | Existing route (150 credits + 1 year) | New route (degree + 2 years) |
|---|---|---|
| Bachelor's degree complete | May 2026 | May 2026 |
| Extra 30 credits (two semesters) | May 2027 | Not required |
| Required experience | 1 year, to May 2028 | 2 years, to May 2028 |
| Earliest licensure | About May 2028 | About May 2028 |
Both routes reach a license at about the same point, 24 months after graduation. The difference is how the second year is spent. On the new route the candidate works and earns during that year, and the firm gets a second year of supervised production from the person. On the existing route that year goes to coursework.
The practical result for the future of accounting firms is that the license supply does not jump in the next few years. Firms that hire under the new route in 2026 will see those hires licensed around 2028, and only in states that have adopted the change. Review and sign-off capacity, which rests with licensed staff, stays the tightest resource until then. Firms trying to win early-career candidates can use the new route as a recruiting point, as our guide to attracting Gen Z accountants explains.
Two IRS rules already shape how firms file. Under the e-file requirement for specified tax return preparers, a preparer who reasonably expects to file 11 or more covered returns in a calendar year must file those returns electronically. Covered returns are income tax returns of individuals, trusts and estates. Firms count returns together for this threshold, so most firms that prepare individual or fiduciary returns fall under it.
The second change is the move from FIRE to IRIS for information returns. In IR-2026-99, dated 24 August 2026, the IRS set 19 November 2026 at 3 p.m. ET as the last day to file information returns through FIRE. Current FIRE users must move to IRIS to file tax year 2026 information returns during the 2027 filing season. IRIS offers a free web-based Taxpayer Portal for up to 100 returns at a time and an Application to Application channel for larger volumes filed through software.
These shifts reward firms that run filing as a documented process with clear system access, transmitter roles and reconciliations. They also make filing work easier to split between onshore and outsourced staff, since the steps are the same wherever the preparer sits. Our FIRE to IRIS checklist for CPA firms covers the transition steps in detail.
US firms with UK clients, UK subsidiaries of US clients or UK operations of their own should note a mandate outside the US. In its consultation response on electronic invoicing, updated 26 November 2025, the UK government states that it "will introduce mandatory e-invoicing for all VAT invoices from 2029." VAT invoices are typically issued for business-to-business and business-to-government transactions.
As of October 2026, the technical standard has not been fixed. The government has said it will develop e-invoicing standards and publish an implementation roadmap at Budget 2026, so details may change. Firms serving UK entities should plan for invoice data that arrives in structured form, which changes how bookkeeping teams capture and match transactions. Our guide to MTD for VAT digital links and the 2029 e-invoicing mandate covers the UK rules.
On 24 June 2026, the IRS Office of Professional Responsibility published Issue Number 2026-19, Introductory Guidelines for Responsible AI Use in Federal Tax Practice. It applies existing Circular 230 duties to AI and shapes how firms will run tax work through 2030 in four ways.
Review stays human. The guidance says practitioners "must thoroughly review all AI-created documents" before delivery to a client or the IRS, and that they "cannot rely solely on AI." Firms that adopt AI still need trained reviewers, which keeps review capacity central to the future firm model.
Fees must reflect AI efficiency. Under section 10.27, the guidance says cost savings "should be passed on openly" and that billing for time not actually spent or double billing for AI-assisted tasks may violate the rule, depending on the facts. This pushes firms toward pricing based on scope and value, which our guide to CPA firm pricing strategy and value-based fees covers.
Competence includes the technology. Under section 10.35, practitioners "must understand both the law and the technology used in their representation of clients before the IRS." Training budgets will need to cover AI tools alongside tax law updates.
Provider tools must be vetted. Under section 10.36, the guidance says "Outsourced or third-party AI tools should be vetted," with the steps documented. It also says client data should be handled "using only secure, enterprise-approved AI." Any outsourcing contract signed between now and 2030 should cover which AI tools the provider's staff use on firm files.
How to choose and roll out AI tools is a separate subject. Our guides to implementing AI in your accounting department and outsourcing vs automation in accounting cover tool selection and the split of tasks between software and people.
Taken together, these changes point to one operating model. Licensed staff onshore concentrate on review, sign-off, client relationships and advisory work. Preparation, reconciliation and data work move into documented workflows run by a mix of software and an outsourced or offshore team. The firm's technology and operations role becomes a permanent seat, since filing channels and AI governance both need an owner.
The exact headcount mix depends on the firm's size, service lines and client base, and no official source sets a standard ratio. A firm can model its own costs at different team sizes with our offshore vs onshore accounting team cost model.
A transition of this kind is usually staged over several years. A typical sequence looks like this.
Leadership agreement. Partners need a shared view of the target model and the time to manage the change. Treating it as a cost exercise alone tends to stall at the first quality issue.
A capable outsourcing partner. Production work depends on the provider's work quality and data security. Our guide to vendor risk assessment for accounting firms lists what to check before signing.
Advisory skills that are built on purpose. Freed capacity only adds value if staff are trained and the firm has services to sell. Tax planning grows naturally from tax compliance, and CFO-style reporting grows from bookkeeping and financial statement work.
Active technology management. AI tools and filing systems need ongoing configuration under written policies, which is why the operations role matters.
Clear client communication. Clients should understand who does their work, how their data is kept secure and what consents apply. Firms that explain the model early tend to face fewer objections later.
What is the future of accounting firms by 2030? Based on official data, firms will face steady demand with hiring driven mostly by replacement, a slow increase in licensed CPAs as states adopt the new pathway, more electronic filing through systems such as IRIS, and IRS expectations for human review of AI output. Most firms will respond by keeping review and advisory work onshore and moving preparation work into documented workflows supported by software and outsourced teams.
Will the new CPA pathway solve the staffing shortage? Not quickly. Candidates on the degree-plus-two-years route still need two years of experience, so 2026 graduates reach licensure around 2028 at the earliest, and only in states that have adopted the change. Review capacity is likely to stay tight in the meantime.
Does the IRS allow tax firms to use AI? Yes. IRS OPR Issue Number 2026-19 does not prohibit AI. It says practitioners must review AI-created documents before delivery, understand the technology they use, pass on cost savings openly and vet outsourced or third-party AI tools.
Will clients accept work done by an outsourced team? Clients generally focus on accuracy, turnaround and access to their CPA. Firms that explain the model, obtain any required consents before sharing client data and keep review onshore are in the best position to keep client confidence.
Does UK e-invoicing affect US accounting firms? It affects US firms that serve UK clients or UK subsidiaries of US groups. The UK plans mandatory e-invoicing for all VAT invoices from 2029, with an implementation roadmap promised at Budget 2026.
