Best contractor accountants – 8 things to look out for

contractor accountant

Whether you’re dipping your toes into contracting for the first time or a seasoned pro, a good accountant is essential.

The right contractor accountant will take care of your tax paperwork and help you make sure you don’t pay more than you have to.

More importantly, they’ll advise you on complicated rules like IR35, so you can concentrate on your work without having to worry about dealing with HMRC.

Of course, hiring a contractor accountant is a personal thing. They’re someone you’ll be working with closely and trusting with your money (hopefully for many years to come).

So how do you make sure you choose the best contractor accountant?

When should you hire a contractor accountant?

Before we discuss choosing an accountant, a quick word on when to hire one.

While you might think it’s a big expense — especially if you haven’t made any money from contracting yet — it’s worth hiring one before you even start for two reasons:

  • They’ll make the process of setting up as a contractor much smoother
  • They’ll advise you on your tax obligations

Most clients and recruiters won’t hire you unless you work through an intermediary (i.e. a company).

So you’ll have to choose whether to join an umbrella company or incorporate on your own.

If you decide to go it alone, a good accountant can set up your limited company for you and make sure it meets all the legal requirements.

The accountant will also take care of other requirements such as registering you as an employer (you’ll need to do this to pay your salary).

More importantly, your accountant can advise you on how and when to deduct business expenses, maintain record-keeping, and comply with relevant legislation (like IR35).

That way, you can make sure that all your Is are dotted and your Ts crossed right from the start.

Here is a table of some of the best-known accountants in the industry.

With that out of the way, it’s time to discuss picking the right contractor accountant.

Here are eight things you should consider.

1. What qualifications do they have?

It goes without saying, but you should only work with an accountant if they’re suitably qualified.

They should have an AAT foundation certificate at a minimum. This entry-level qualification gives a good grounding in bookkeeping, costing, and other basic issues of financial administration.

More experienced accountants will typically:

  • Have an accountancy degree, a more advanced AAT qualification, or an ATT, ACCA, or CIMA qualification
  • Be affiliated with a professional body such as:
    • ICAEW (Institute of Chartered Accountants in England and Wales)
    • ICAS (Institute of Chartered Accountants in Scotland)
    • ACCA (the Association of Certified Chartered Accountants)
    • CIMA (the Chartered Institute of Management Accountants)

Professional accountancy bodies have specific training and continuing professional development requirements.

So if your accountant belongs to one, it shows they’re serious about meeting high standards of expertise and professionalism.

It’s worth looking them up on professional bodies’ member directories to confirm their credentials.

In many cases, the firm itself will hold the relevant qualification(s), not necessarily members of staff who do much of the day-to-day paperwork.

In other words, you’ll likely have an ‘account manager’ who handles day-to-day issues and tasks. They might be training for an accounting qualification themselves.

They will need to seek approval from a qualified accountant when finalising your company accounts, as well as certain other duties.

2. Do they specialise in contracting?

As a contractor, you must comply with complex and tricky legislation, such as IR35 and the rules around expenses. If you get these wrong, you can suffer dire financial consequences.

You’ll also want to keep your tax bill as low as possible.

Many contractors do this by paying themselves a small salary and taking the rest of their income as dividends.

But if your salary is so small it puts you under the primary threshold, you may lose out on the benefits of National Insurance contributions. And if you’re not careful when you declare dividends, you may also fall foul of HMRC’s rules.

Not all accountants understand how contractors work and get paid or are up-to-date with the latest tax laws that apply to contractors. Working with someone who’s clued up will help you make sure you don’t run into issues down the line.

3. Individuals vs accountancy firms: who should you go for?

Like other businesses, accountants can vary enormously in size — from one-man bands to large firms with thousands of employees across the country (or even across the globe). Both have pros and cons.

A larger firm with many employees will probably have a wider skill set. They’ll be more likely to have worked with contractors before. They may also be able to offer you valuable additional services such as financial advice and legal support.

The flip side is that you’ll probably be a small and lower-priority client for them. This means you may be assigned to a junior or get shifted from one accountant to another, depending on who is available.

Chances are the service will also be more impersonal. And because larger firms have bigger overheads, you can expect to pay more.

A smaller firm or an individual may be able to offer you a more tailored personal service at a lower cost.

That said, they may not always have the expertise to meet your needs in-house or be able to provide additional services.

They may also be less responsive when things get busy, especially if they have higher-paying clients to deal with.

4. Are they comfortable with technology?

How will you submit your records and financial information to your contractor accountant?

Will you pack up your shoebox of receipts and mail it to them, after which they’ll mail back physical copies of your accounts and tax paperwork for you to sign? Or is everything paperless and online?

These days, almost all accountants will ask you to upload to an online portal, have their own bespoke digital platform, or use third-party accounting software such as Xero, the excellent FreeAgent, or Quickbooks.

HMRC doesn’t specify what format your financial records should be in, as long as they’re complete, accurate, and readable.

So whether you go with a paper-based accountant (as unlikely as this seems) or someone who’s hip to the latest technology is largely a matter of personal preference.

Based on our experience, we strongly recommend hiring a FreeAgent accountant. We’ve used the software since 2010 ourselves – it is tailor-made for contractors, and accountants also love it. It makes keeping on top of your accounts a breeze.

5. How much do they charge?

The amount accountants charge varies wildly. Expect to pay as little as £50 a month or £150 a month or more.

Be aware that most accountants quote their rates exclusive of VAT. This means you need to add 20% to their fees. So if an accountant says they charge £100 a month, that’s actually £120 a month.

This isn’t an issue if you’re VAT registered, as your business can reclaim the VAT element.

You should also check what’s included in the fee. As a minimum, you should expect it to include:

  • Preparation of your annual company accounts
  • Company tax returns and VAT filings
  • Handling of correspondence from HMRC and Companies House
  • A certain amount of contact hours so you can ask questions and get advice and support with your tax affairs

The old adage goes that you get what you pay for. But this isn’t necessarily the case with accounting.

While you should check what’s included in the fees and shop around, don’t make it all — or even mostly — about price.

What’s more important is that you partner with someone you’re comfortable with, is efficient and responsive, and who gives you good advice.

6. What’s NOT included in the accountant’s fees?

Just as important as what’s included in the fee quote is what’s not included. Services you may want to enquire about (but may not be included in the fee) are:

  • Incorporating your limited company.
  • Companies House filings — you must file your accounts and a confirmation statement every year, and you’ll have to pay late filing penalties if you miss the deadlines
  • Your personal tax calculation and self-assessment tax return (this is a personal, not a business expense).
  • Payroll. If you use accounting software such as Xero or FreeAgent, running this yourself is fairly straightforward. But you may want to offload the responsibility. Most contractors do.
  • References. For example, if you’re applying for a mortgage
  • Providing a third party address for your company (and service address for directors).

Most reputable accountants will ask you to sign an engagement letter. This will specify what’s included and what’s not included in their fee, as well as their terms and conditions. But if you’re still unclear, it doesn’t hurt to ask.

7. What’s their reputation like?

Your accountant may have a shiny logo, a slick website and affiliations with professional bodies. But that doesn’t necessarily mean they have a good reputation with your fellow contractors.

In fact, some of the best contractor accountants have pretty basic websites.

Do they live up to the hype? Or are they infamous for their shoddy service?

Google reviews and comparison websites can be a good starting point for checking this out. That said, it’s not always possible to tell genuine reviews from fake ones. Some reviews may be paid for. And some may be written by people with an axe to grind.

With this in mind, you should take reviews with a pinch of salt.

Once you make a shortlist of possible contractor accountants you could work with, the best approach is to ask people you know and trust for their thoughts.

Speak to fellow contractors or ask in professional groups such as LinkedIn. You’ll be more likely to get an unbiased opinion and trustworthy recommendations.

8. How responsive are they?

How efficient is your accountant? Do they quickly respond to your queries? Or do you have to chase them for days to get a simple yes or no reply?

At best, an accountant who is often unavailable or unreachable is frustrating to deal with. At worst, it may mean you’re not a priority for them, leading to missed deadlines, incorrect advice, and trouble with HMRC.

Of course, you won’t know what someone’s like before you start working with them.

That said, it’s worth calling or emailing accountants you’re interested in working with.

If someone isn’t open and helpful when trying to win your business, chances are they’ll be hard to deal with when they sign you up, too.

And if your relationship with your accountant sours, don’t be afraid to switch.

While finding someone new and getting them up to speed may seem like a hassle, the peace of mind that your tax affairs are in order and taken care of is well worth it.

The best contractor accountants are worth their weight in gold

Hiring an accountant may feel like a big expense, especially if you’re just starting out as a contractor.

But if you choose wisely, you’ll make the fees back in tax savings and by staying on the right side of HMRC.
