Why Hire an Accountant for Your Practice And When Outsourcing Makes More Sense

Hiring a full-time accountant on a £32,000 salary really costs £42,000–£48,000 in year one once employer NI, pension, recruitment fees and onboarding are included. UK practices should hire in-house for long-term client ownership, or outsource to a specialist partner for compliant, scalable capacity — often at 30–40% lower cost, with no recruitment delay.

Most practice owners we speak to aren’t asking whether they need more accounting resources. They already know they do. The question is how to get it, and whether hire an accountant is actually the right move.

Maybe you’ve been meaning to post that job ad for six weeks. Maybe your best bookkeeper just handed in notice. Or maybe January came and went, and you promised yourself you’d sort the capacity problem before the next peak.

This guide is for UK accounting practices working through exactly that. We’ll cover what to look for when you hire an accountant, the real costs involved in 2026, and why a growing number of practices are finding that outsourcing solves the problem faster — and cheaper — than a traditional hire. For larger, multi-partner practices in particular, the maths changes fast: recruiting one qualified hire at a time doesn’t scale against rising client volumes, which is where a blended in-house-plus-outsourced model tends to win.

Key Takeaways

• 67% of UK accounting firms struggle to recruit qualified staff — and 60% face retention challenges (ICAEW, 2025).
• Hiring a full-time accountant costs more than the salary alone. Employer NI, pension, and recruitment fees push the real cost of a £32k hire to £42,000+.
• HMRC’s tax gap hit £46.8 billion in 2023–24, 60% from small businesses. Your clients are under more scrutiny than ever.
• Outsourcing to a specialist UK partner like Corient can cut back-office costs by up to 40%, with no recruitment delays.
• There were 2.73 million VAT- and PAYE-registered businesses in the UK as of March 2025 (ONS, 2025) — a growing compliance base that larger, multi-partner practices are best placed to capture with the right resourcing.

What Accountants Really Do

Accountants really do three things — keep clients compliant with HMRC and Companies House, catch errors before they become penalties, and give proactive advice that helps clients make better financial decisions.

Tax compliance in the UK has never been more complex — or more closely watched. HMRC’s tax gap reached £46.8 billion in 2023–24, with 60% of that gap attributed to small businesses. That’s not a coincidence. It’s a reflection of the volume of errors, omissions, and late filings that happen when businesses try to handle accounting themselves — or when their practice doesn’t have the right resource to catch the problems in time.

That’s exactly why good accountants matter. They don’t just file returns — they keep your clients compliant, flag risk before it becomes a penalty, and give you the confidence to take on more work.

Accounting practices have two options when it comes to getting that resource: hire in-house, or outsource to a specialist partner. Both work. The right choice depends on what your practice actually needs. Outsourced accounting means contracting a specialist external team to deliver bookkeeping, payroll, tax, or year-end work under your practice’s brand and software, rather than employing that capacity directly.

5 Reasons Accounting Practices Prioritise Hiring a Qualified Accountant

Practices prioritise hiring qualified accountants because it protects compliance accuracy, unlocks advisory revenue, keeps payroll and bookkeeping error-free, and ensures HMRC and Companies House obligations are met on time.

When accounting firms hire a good accountant, they add value to their accounting services and ensure your processes are compliant with HMRC regulations. Your clients will also make important financial decisions based on the information and reports provided by your accountants. Furthermore, there are multiple other benefits when you hire an accountant, which we examine in detail.

Complex Compliance Work Gets Done Accurately and on Time

VAT returns, corporation tax submissions, Self Assessment — these are high-stakes tasks where errors don’t just cause embarrassment, they trigger HMRC investigations and automatic penalties. A qualified accountant knows exactly where the risk sits: in that large VAT payment your client keeps miscalculating, or in the R&D claim that hasn’t been properly substantiated.

53% of small companies had errors in their tax returns in 2021–22 (HMRC Random Enquiry Programme). Your job is to make sure your clients aren’t in that group. Corient’s VAT outsourcing and year-end accounts teams are built specifically to close that gap.

Your Clients Get Genuine Financial Advice, Not Just Compliance

Qualified accountants aren’t just compliance processors — they’re advisors. The best ones are watching tax rule changes, spotting planning opportunities, and helping your clients make better business decisions before year-end arrives.

That advisory value is increasingly what clients are paying for. Practices that can offer proactive tax planning and financial guidance alongside standard compliance work retain clients longer and command higher fees.

Payroll Is Handled Properly — Every Pay Period

Payroll sounds straightforward until something goes wrong — a wrong tax code, a missed RTI submission, a pension auto-enrolment error. Experienced accountants set up and run payroll correctly, handle PAYE calculations, and ensure your clients’ pension obligations are met with the Pensions Regulator.

If your in-house team doesn’t have the bandwidth, this is one of the easiest areas to outsource. Corient’s team works across payroll software like Sage, Brightpay, Xero, Moneysoft, Earnie, and Star Payroll — whichever your clients use.

Bookkeeping Stays Clean — Which Means Everything Else Runs Faster

Good bookkeeping isn’t glamorous, but it’s the foundation everything else sits on. When the books are clean — reconciliations done, transactions categorised correctly, VAT tracked properly — your accounts prep is faster, your advisory work is more accurate, and your year-end isn’t a scramble.

The problem is that bookkeeping is time-consuming. If your senior accountants are spending hours on bank recs instead of client-facing work, that’s a capacity problem. It’s also one of the most common reasons practices start looking at outsourcing.

HMRC and Companies House Dealings Are Handled Properly

A qualified accountant keeps your clients’ financial records in order, ensures payments to HMRC are forecast and made on time, and prepares annual accounts for Companies House submission where required. They also conduct regular reviews to catch systemic errors before they become compliance issues.

With HMRC recruiting 5,500 new compliance officers and 2,400 debt management staff (Spending Review 2025), the days of errors slipping through unnoticed are over. Your clients need someone who stays ahead of that — not someone who reacts to enquiry letters.

What Is the Cost of Hiring an Accountant?

The real first-year cost of hiring a £32,000-salaried accountant is £42,000–£48,000 once employer National Insurance, pension auto-enrolment, recruitment fees and onboarding time are added — 30–40% more than the headline salary.

Yes, hiring an experienced accountant costs money. But most practices underestimate the true figure.

A £32,000 salary is just the start. Add employer National Insurance (13.8% above the secondary threshold), pension auto-enrolment, recruitment agency fees (typically 15–20% of first-year salary), onboarding time, and software licences — and the real first-year cost of that hire is closer to £42,000–£48,000. That assumes the hire works out.

For context, here’s what your clients typically pay when they hire an accountant for their business:

Service	Typical 2025 Cost
Self Assessment (sole trader)	£150 – £400 per return
Monthly bookkeeping	£100 – £500/month
Ltd company year-end + CT600	£750 – £2,000/year
VAT returns (quarterly)	£100 – £300/quarter
Full monthly package	£60 – £450/month
Specialist advisory	£125 – £250/hour

Compare that to outsourcing. Corient’s pricing is transparent, fixed, and scales with your workload. Practices that make the switch typically save 30–40% on equivalent in-house costs — with no recruitment risk.

When Should Your Clients Hire an Accountant — and What Should You Tell Them?

Clients should hire their own in-house accountant once they outgrow basic compliance needs — typically when they take on staff, run payroll, or face complex VAT or R&D work. Before that stage, a good accounting practice covers everything they need.

When your clients ask whether they should hire their own accountant, the answer depends on where they are in their growth.

Early-stage sole traders and micro businesses usually don’t need a full-time accountant. What they need is a good accounting practice — one that handles their Self Assessment, VAT, and compliance accurately and efficiently. That’s where you add the most value.

As a client grows — taking on staff, managing payroll, dealing with complex VAT or R&D credits — the volume and complexity of work increases. At that point, you might recommend they appoint a Finance Director or in-house accountant for day-to-day financial management, while continuing to use your practice for compliance and advisory work.

For practices, the key is not losing clients to competitors when they scale. The way you do that is by expanding your service offering — either by hiring more qualified accountants or by outsourcing to a partner who can handle the additional volume under your brand.

Any accountant you hire — or outsourcing partner you work with — needs to be certified and actively working in MTD-compatible software: Xero, QuickBooks, Sage, IRIS, or TaxCalc.

The Bottom Line: Hire, Outsource, or Both?

The bottom line: hire in-house for embedded, long-term client ownership; outsource for fast, lower-cost, compliant capacity; most competitive UK practices now do both.

The honest answer is: it depends on what you actually need.

If you need someone embedded in the team — a trusted senior who owns client relationships and grows with the practice — hire in-house. Take the time to get the qualifications, experience, and fit right.

If you need reliable, qualified accounting output delivered on deadline — and you need it now, without a 12-week recruitment process — outsourcing is worth a serious look.

A lot of practices end up doing both: a small, senior in-house team focused on client relationships and advisory work, with a specialist outsourcing partner handling the volume behind the scenes. That combination is increasingly how UK practices stay competitive without constantly fighting the hiring market.
