Introduction: VAT and the UK Law Firm

VAT is a significant cost for most UK law firms. Legal services, including conveyancing, litigation, and commercial advice, are standard-rated for VAT at 20%. If your firm is VAT-registered, you must charge VAT on your fees and account for it to HMRC. The standard method requires you to reclaim input VAT on your business purchases and pay over the net difference to HMRC.

For many solicitors, the Flat Rate Scheme (FRS) offers an alternative. Instead of reclaiming input VAT on each purchase, you apply a fixed percentage to your VAT-inclusive turnover and pay that amount to HMRC. The difference between the VAT you charge clients and the flat rate payment is your profit. But is FRS right for your law firm? The answer depends on your cost base, the type of work you do, and whether you qualify as a "low cost trader."

This guide explains the FRS rules, how they apply to solicitors, and when standard VAT accounting may be more beneficial. We also cover the low cost trader test, which can change your flat rate percentage significantly.

How the Flat Rate Scheme Works for Solicitors

The Flat Rate Scheme is a simplified VAT accounting method. Instead of recording every input VAT amount and reclaiming it, you apply a single flat rate percentage to your gross turnover (including VAT). You pay that amount to HMRC and keep the rest. For example, if your flat rate is 12% and you bill a client £1,200 including VAT, you pay HMRC £144 and keep £56 of the VAT you collected.

The standard flat rate for a law firm is 14.5% of gross turnover. This rate applies to most legal activities, including solicitors, barristers, and other legal professionals. However, there are important exceptions and adjustments.

Flat Rate Percentage for Solicitors

HMRC publishes a list of trade sectors with corresponding flat rates. The sector "Legal services" has a flat rate of 14.5%. This covers solicitors, barristers, and other legal professionals. If your firm provides a mix of services, you use the rate for your main business activity.

There is a key exception: if your firm qualifies as a "low cost trader," the flat rate drops to 12%. This can make a significant difference to your VAT profit. We explain the low cost trader test in detail below.

What You Cannot Reclaim Under FRS

Under the Flat Rate Scheme, you cannot reclaim input VAT on most business purchases. This includes office supplies, rent, utilities, and professional fees. The flat rate already accounts for a typical level of input VAT recovery. However, there are two important exceptions:

  • Capital assets over £2,000 including VAT: You can reclaim input VAT on individual capital assets costing more than £2,000 (including VAT). This includes computers, office furniture, and certain equipment.
  • VAT on goods bought for resale: If you buy goods specifically for resale (not services), you can reclaim the input VAT. This is rare for solicitors, as most firms sell services, not goods.

For most law firms, the inability to reclaim input VAT on everyday expenses is the main drawback of FRS. If your firm has high input VAT costs, standard VAT accounting may be better.

The Low Cost Trader Test: What It Means for Your Law Firm

The low cost trader test determines whether you can use the lower flat rate of 12% instead of the standard 14.5%. This test applies to all businesses using FRS, including solicitors.

You are a low cost trader if your VAT-inclusive expenditure on goods (not services) is less than 2% of your VAT-inclusive turnover, or less than £1,000 per year if the 2% test gives a figure above £1,000. "Goods" means physical items you buy and use in your business, such as stationery, computer hardware, and office furniture. It does not include services like rent, utilities, professional fees, or subcontractor costs.

For a typical law firm, most expenditure is on services (rent, utilities, professional indemnity insurance, software subscriptions, and staff salaries). Staff salaries are outside the scope of VAT entirely. This means many solicitors may pass the low cost trader test and qualify for the 12% rate. However, you must check carefully. If your firm spends heavily on physical goods, such as a large library of legal textbooks or significant IT hardware, you may fail the test.

The low cost trader test is applied annually. If you qualify in one year but not the next, you must switch to the 14.5% rate from the start of the next VAT period. HMRC provides detailed guidance on what counts as goods versus services, and we recommend you review this with your accountant.

FRS vs Standard VAT Accounting: A Comparison for Solicitors

To decide which method suits your law firm, compare the net VAT position under each approach. Here is a worked example for a typical small law firm.

Example: Small Conveyancing Firm

Consider a sole practitioner solicitor with annual VAT-inclusive turnover of £120,000. The firm's VAT-exclusive turnover is £100,000, and it charges 20% VAT on all fees. The firm's VAT-inclusive expenditure on goods and services is £30,000, of which £20,000 is on services (rent, utilities, insurance) and £10,000 on goods (stationery, IT equipment, legal texts).

Standard VAT accounting:

  • Output VAT charged to clients: £20,000 (£100,000 x 20%)
  • Input VAT recoverable: £5,000 (£30,000 x 20% / 120% x 20%, simplified: £30,000 / 6 = £5,000)
  • Net VAT payable to HMRC: £15,000

Flat Rate Scheme (14.5%):

  • Flat rate payment: £17,400 (£120,000 x 14.5%)
  • VAT retained by firm: £2,600 (£20,000 - £17,400)
  • Net VAT cost: £17,400 paid to HMRC, but you keep £2,600 of the VAT you collected

Under standard accounting, you pay £15,000. Under FRS at 14.5%, you pay £17,400. Standard accounting saves you £2,400 per year.

Now check the low cost trader test:

Goods expenditure is £10,000. VAT-inclusive turnover is £120,000. 2% of turnover is £2,400. Since £10,000 exceeds £2,400, the firm does NOT qualify as a low cost trader. The 14.5% rate applies.

If the firm's goods expenditure were only £1,500, it would pass the test and use 12%:

  • Flat rate payment: £14,400 (£120,000 x 12%)
  • VAT retained by firm: £5,600
  • Net VAT cost: £14,400 paid to HMRC

Now FRS at 12% saves £600 compared to standard accounting (£15,000 vs £14,400). The low cost trader test makes FRS attractive for firms with minimal goods expenditure.

When Should a Solicitor Choose the Flat Rate Scheme?

FRS works best for law firms with low input VAT costs. If your firm spends little on goods and services that carry VAT, you may benefit from the simplified accounting and the VAT profit you retain. Typical candidates include:

  • Sole practitioners working from home with minimal office expenses
  • Firms with low rent and utility costs (e.g., shared offices where the landlord charges no VAT)
  • Firms that subcontract little work and buy few physical goods

FRS also reduces administrative burden. You do not need to track every input VAT receipt. This can save time for the COFA or the person managing VAT returns.

However, FRS is rarely the best choice for larger law firms or those with significant VAT-bearing costs. If your firm spends heavily on professional fees, IT systems, or office fit-outs, standard VAT accounting allows you to reclaim that input VAT. The 14.5% flat rate is punitive for firms with high costs.

When Standard VAT Accounting Is Better

Standard VAT accounting is almost always better for law firms that:

  • Have high rent or property costs (commercial property rent is standard-rated for VAT)
  • Spend heavily on IT hardware and software
  • Use subcontractors who charge VAT
  • Incur significant professional fees (accountants, barristers, expert witnesses)
  • Have a high proportion of input VAT relative to output VAT

For example, a mid-sized litigation firm with annual turnover of £500,000 and input VAT costs of £60,000 would pay £72,500 under FRS at 14.5% but only £40,000 under standard accounting (output VAT £100,000 minus input VAT £60,000). Standard accounting saves £32,500 per year.

If your firm is considering FRS, run the numbers with your accountant first. The simplified accounting may not compensate for the lost input VAT recovery.

Practical Steps for Switching to FRS

If you decide FRS is right for your law firm, follow these steps:

  1. Check eligibility: Your VAT-exclusive turnover must be £150,000 or less to join FRS. Once registered, you can stay on FRS until your turnover exceeds £230,000 (including VAT).
  2. Apply to HMRC: You can apply online through your HMRC business tax account. The application is straightforward.
  3. Determine your flat rate: Use the 14.5% rate for legal services, unless you qualify as a low cost trader (then 12%).
  4. Adjust your accounting: From the start date, calculate VAT on a gross turnover basis. You cannot reclaim input VAT on most purchases from that point.
  5. Notify HMRC of changes: If your circumstances change (e.g., you fail the low cost trader test), tell HMRC promptly.

You can leave FRS at any time. If you leave, you must use standard VAT accounting from the start of your next VAT period.

Common Pitfalls for Solicitors on FRS

Several issues trip up solicitors using the Flat Rate Scheme:

  • Incorrect sector classification: Some solicitors mistakenly use a lower rate for a different sector. HMRC can assess backdated VAT if you use the wrong rate.
  • Failing the low cost trader test: If you use 12% but do not qualify, HMRC will charge the difference plus interest and penalties.
  • Forgetting the capital asset rule: You can reclaim input VAT on capital assets over £2,000. Many firms miss this and lose money.
  • Not reviewing annually: The low cost trader test and your turnover must be reviewed each year. If your circumstances change, your rate may change.

We recommend you work with a solicitor accountant who understands VAT rules for law firms. They can help you decide whether FRS is right and ensure you comply with HMRC requirements.

Conclusion: FRS Is Not a One-Size-Fits-All Solution

The Flat Rate Scheme can simplify VAT accounting for some law firms, particularly sole practitioners and small firms with low input VAT costs. The low cost trader test makes FRS more attractive for firms that spend little on physical goods. However, for most law firms with typical overheads, standard VAT accounting results in a lower net VAT bill.

Before switching, calculate your net VAT position under both methods. Consider your current and expected expenditure on goods and services. If you are unsure, speak to a legal-sector-specialist accountant. They can model the numbers for your specific firm and help you avoid costly mistakes.
