What Is Goodwill Stripping in a Dental Practice Context?
Goodwill stripping is the process of extracting value from a dental practice before a sale, so that the proceeds are taxed as income or dividends rather than as a capital gain. The goal is to reduce the overall tax bill, because income tax rates (up to 45%) can be lower than CGT rates (up to 24%) in certain circumstances, or because the extracted value benefits from lower corporate tax rates before distribution.
For a dental practice owner, this typically means paying yourself or your family members a bonus, dividend, or pension contribution in the year or two before the sale, funded by the practice's retained profits. The effect is to reduce the company's net asset value and, critically, the value of goodwill that would otherwise be taxed as a capital gain on disposal.
HMRC scrutinises goodwill stripping closely. If the extraction is linked to the sale (for example, a large dividend paid six months before exchange), it can be recharacterised as part of the sale proceeds and taxed as a capital gain. The key is timing and commercial justification.
How Does Goodwill Stripping Work in Practice?
Consider a dental practice company with the following simplified balance sheet:
- Net assets (excluding goodwill): £200,000 (cash, equipment, debtors less creditors)
- Goodwill: £600,000
- Total net assets: £800,000
If you sell the company for £800,000, your capital gain is roughly £800,000 less your base cost (say £100,000 for shares originally subscribed). At 24% CGT (higher rate, 2025/26), that's £168,000 tax. At 14% BADR, it's £98,000.
Now suppose in the year before sale, you extract £200,000 as a dividend. The company's net assets drop to £600,000. The sale price falls to £600,000 (assuming the buyer values the business on net assets plus goodwill). Your capital gain is now £500,000. At 24% CGT, that's £120,000 tax. The dividend is taxed at 33.75% (higher rate) = £67,500. Total tax: £187,500. That is higher than the original £168,000.
But if you extract the £200,000 as a pension contribution (tax-free in the company, tax-free for you up to the annual allowance), the company saves corporation tax at 19-25% on the contribution. The gain reduces by £200,000, saving £48,000 CGT. The pension contribution itself costs the company nothing net after corporation tax relief. Total tax saved: roughly £48,000.
The arithmetic depends entirely on the extraction method, your personal tax position, and the timing relative to the sale.
What HMRC Looks For: The Anti-Avoidance Risks
HMRC has several tools to attack goodwill stripping:
- Transaction in securities (TAAR) under ITA 2007 Part 13. If you extract value from a company in a way that gives you a tax advantage (e.g., dividend instead of capital gain), and the extraction is connected with a sale, HMRC can recharacterise the dividend as a capital distribution.
- GAAR (General Anti-Abuse Rule) applies if the arrangement is "abusive" and the main purpose is tax avoidance.
- Transfer pricing rules if you extract value to a connected party (e.g., a spouse) at non-commercial rates.
- Value shifting provisions in TCGA 1992 s.29-34 can reallocate gains if value is shifted out of shares before disposal.
HMRC's guidance in the Business Income Manual (BIM) makes clear that pre-sale dividend stripping is a known avoidance area. They will look at the timing, the amount, and whether the extraction was planned before the sale was contemplated.
When Goodwill Stripping Makes Sense for a Dental Practice
Goodwill stripping is most defensible when:
- The extraction is part of a genuine ongoing profit extraction strategy, not a one-off pre-sale event. If you have historically paid yourself regular dividends or pension contributions, a larger one in the final year is easier to justify.
- The extraction is funded by trading profits, not by borrowing or by selling assets. HMRC is more suspicious if the company takes out a loan to pay a dividend just before sale.
- The extraction is commercially justified. For example, you need to fund a pension because you are retiring, or you have a genuine need for cash (e.g., school fees, house purchase).
- The timing gap between extraction and sale is at least 12-24 months. The longer the gap, the harder it is for HMRC to argue the extraction was part of the sale arrangement.
A common approach for dental practice owners is to maximise pension contributions in the 2-3 years before sale. The annual allowance is £60,000 (2025/26), and unused allowances from the previous three years can be carried forward. A principal aged 55+ could potentially contribute £200,000+ into a pension over two years, extracting that value from the company tax-efficiently while reducing the goodwill gain.
Pre-Sale Value Engineering vs Goodwill Stripping
Pre-sale value engineering is a broader concept than goodwill stripping. It includes:
- Reviewing the practice's cost base to maximise EBITDA, which increases the sale multiple.
- Ensuring all capital allowances have been claimed correctly (e.g., on dental chairs, X-ray equipment, compressors).
- Cleaning up the balance sheet: paying off director loans, settling inter-company balances, and removing personal assets.
- Structuring the sale to qualify for BADR (14% in 2025/26, rising to 18% from April 2026).
- Considering whether to sell shares or assets, and the tax implications for both seller and buyer.
Goodwill stripping is one element of pre-sale value engineering, but it must be integrated into a wider plan. A standalone stripping exercise without proper commercial rationale is a red flag for HMRC.

Worked Example: Goodwill Stripping for a Single-Principal Practice
Scenario: Dr Patel owns a single-handed NHS/private mixed practice through a limited company. She plans to sell in 2027. The practice has:
- Annual EBITDA: £180,000
- Goodwill valued at 1.0x EBITDA = £180,000
- Net assets (excluding goodwill): £120,000
- Share base cost: £10,000
Option A: No stripping. Sale price £300,000. Gain £290,000. BADR at 14% = £40,600 tax. Net proceeds £259,400.
Option B: Pension stripping. In 2025/26 and 2026/27, Dr Patel contributes £60,000 each year into her pension (total £120,000). The company saves corporation tax at 19% on each contribution (£11,400 per year). The sale price drops to £180,000 (goodwill £60,000 + net assets £120,000). Gain £170,000. BADR at 14% = £23,800. Total tax saved on sale: £16,800. Plus corporation tax saved on pension contributions: £22,800. Total benefit: £39,600.
Option C: Dividend stripping (risky). Dr Patel pays a £100,000 dividend in 2025/26, then sells in 2026/27. Sale price drops to £200,000. Gain £190,000. Dividend taxed at 33.75% = £33,750. CGT at 14% = £26,600. Total tax: £60,350. Worse than Option A (£40,600). HMRC may also challenge the dividend under TAAR.
Option B (pension stripping) is the most tax-efficient and the most defensible, provided the pension contributions are within the annual allowance and are commercially justified by Dr Patel's retirement plans.
What About Goodwill on a Practice Purchase?
Goodwill stripping is a pre-sale technique. But if you are buying a dental practice, you need to understand how goodwill is treated for tax in your company. Acquired goodwill (post-1 April 2019) qualifies for tax relief at 6.5% per year under the Finance Act 2019 rules. This relief is valuable and should be factored into your acquisition structure.
For more on this, see our guide on practice purchase financial due diligence.
Common Mistakes and How to Avoid Them
- Stripping too close to the sale. HMRC will assume the extraction was part of the sale arrangement. Aim for at least 12 months gap, ideally 24+ months.
- Using dividends instead of pensions. Dividends are taxed at 33.75% (higher rate) and trigger TAAR risk. Pensions are tax-free in the company and for the individual, and are harder for HMRC to challenge if they are part of a genuine retirement plan.
- Ignoring BADR eligibility. BADR gives a 14% CGT rate (2025/26) on the first £1m of qualifying gains. If you strip too much value, you may waste BADR headroom. The optimal strategy is to extract value up to the point where the remaining gain fits within the BADR limit.
- Not documenting the commercial rationale. HMRC will ask why you extracted the value. If you cannot show a genuine business or personal reason (e.g., retirement funding, debt repayment, school fees), the arrangement looks like avoidance.
- Stripping from a company that has no retained profits. A dividend paid from capital (not distributable reserves) is unlawful under company law and may be treated as a capital distribution by HMRC.
Is Goodwill Stripping Right for Your Dental Practice?
Goodwill stripping is not a one-size-fits-all technique. It works best for principals who:
- Have a clear retirement timeline (2-5 years out).
- Have unused pension annual allowance headroom.
- Are selling a company (not a sole trade or partnership).
- Have a practice with significant retained profits that can be extracted without borrowing.
It is less suitable for:
- Principals selling within 12 months (too little time to create a defensible gap).
- Practices with low retained profits (nothing to extract).
- Principals who have already used their BADR lifetime limit.
- Sole traders or partnerships (goodwill stripping works through a company structure).
If you are considering a sale, start planning at least 2-3 years in advance. A well-timed pension contribution strategy, combined with proper documentation of commercial rationale, is the most robust approach.
For a detailed analysis of your specific situation, speak to a dental-specialist accountant who understands both the tax rules and the dental practice market.
Next Steps: Pre-Sale Planning Checklist
- Confirm your sale timeline (target date).
- Review your company's retained profits and distributable reserves.
- Check your pension annual allowance and carry-forward position.
- Assess BADR eligibility and headroom.
- Document your commercial rationale for any pre-sale extraction.
- Engage a dental-specialist accountant at least 2 years before the planned sale.
