Should You Switch to a Limited Company
Just to Avoid MTD?
Every year, thousands of UK sole traders ask their accountant the same question when a new tax rule arrives: "should I just go limited?" With MTD, the question has a genuine, factual answer, incorporating does take you out of MTD ITSA scope. But whether it's worth it is a completely different question, and the honest answer is: usually not, if MTD avoidance is your only reason.
Does Incorporating Actually Avoid MTD?
Yes — factually, this works. Here's exactly why:
- MTD for Income Tax Self Assessment applies to self-employment income and personal UK property rental income held by an individual
- If you incorporate, your trading income becomes the limited company's income, not yours personally — you instead receive salary and/or dividends from the company
- Salary and dividends are both excluded from MTD qualifying income. Confirmed in our dedicated guide on dividends
- HMRC has confirmed it does not intend to introduce MTD for Corporation Tax (Transformation Roadmap, July 2025) — limited companies will continue filing standard Corporation Tax returns (CT600), with no MTD-style quarterly reporting requirement
So in pure technical terms: incorporate, and your trading income is no longer subject to MTD ITSA. This is accurate. The problem is what people overlook next.
The Real Cost of Incorporating — Beyond MTD
MTD software costs roughly £150–£300 per year for most sole traders (see our full software comparison — and Zoho Books offers a genuinely free tier for income under £35,000). Compare that to the ongoing costs of running a limited company properly:
| Cost | Typical Annual Range |
|---|---|
| Annual accounts + Corporation Tax return (accountant fee) | £500–£1,200 |
| Payroll administration (if taking a salary) | £150–£350 |
| Companies House confirmation statement | £34 (filing fee) |
| Dividend voucher / shareholder paperwork | Often included in accountant fee |
| Increased general accountancy complexity | £200–£600 extra vs sole trader accounts |
| Typical total additional cost vs sole trader | £900–£2,200+ per year |

When Incorporation Genuinely Makes Sense
Incorporating is a legitimate and often smart decision — but the reasons should stand on their own, independent of MTD:
- Profit level — once profits regularly exceed roughly £40,000–£50,000, the combination of Corporation Tax and dividend tax can become more efficient than Income Tax and National Insurance as a sole trader (this threshold shifts with tax rate changes, get current advice)
- Limited liability — if your business carries genuine risk of being sued or incurring large debts, the legal separation between you and the company matters regardless of tax
- Client requirements — some larger clients or contracts require working with a limited company rather than a sole trader, particularly in certain industries
- Profit retention — if you want to leave profit in the business to reinvest rather than draw it all out, a company structure allows this more efficiently than sole trader accounts
- Multiple owners — if you are bringing in a business partner with shared ownership, a company structure with shares is often cleaner than a partnership (note: partnerships currently have no confirmed MTD date either)

Can You Switch Back?
Yes, but it is not simple. Closing a limited company involves formally striking it off at Companies House or going through a Members' Voluntary Liquidation if there are significant retained funds, and can trigger Capital Gains Tax on value extracted from the company. This is not something to do casually as a temporary MTD workaround — once incorporated, reversing the decision has real cost and complexity.
Incorporating Is Not an MTD Exemption — It's a Structural Change
It is worth being precise about language here. Incorporating does not give you an "MTD exemption" — exemptions are a specific category covered in our MTD exemptions guide, for disability, age, religious belief, and similar grounds, granted by HMRC application. Incorporating is a different thing entirely: it restructures your business so that the income in question is no longer personally yours, and therefore simply falls outside MTD ITSA's scope by definition, not by exemption.
Get Proper Advice Before Deciding
This is one of the genuinely high-stakes decisions in small business tax planning. The right call depends on your specific profit level, your industry, your plans for the business, your personal financial situation, and current tax rates, all of which change. A qualified accountant who knows your full picture can run the actual numbers for your situation. This guide gives you the framework to ask the right questions — it is not a substitute for that conversation.
Frequently Asked Questions
Does incorporating as a limited company avoid Making Tax Digital?
Yes, in the sense that MTD for Income Tax applies only to individuals with self-employment or personal rental income, not to limited companies. A limited company files Corporation Tax returns instead, and HMRC has confirmed it does not intend to introduce MTD for Corporation Tax (Transformation Roadmap, July 2025). So incorporating does remove you from MTD ITSA scope for that income.
Is it worth incorporating just to avoid MTD?
Usually not, if avoiding MTD is the only reason. MTD compliance costs roughly £150–£300 per year for software. Incorporating costs significantly more in accountancy fees, Corporation Tax compliance, payroll administration, and potential loss of certain reliefs — often £1,000–£2,000+ per year in additional costs. Incorporation should be driven by genuine tax efficiency or business reasons, not solely MTD avoidance.
What does incorporating actually cost compared to staying a sole trader?
Typical additional costs of running a limited company versus a sole trade include £500–£1,200 per year for annual accounts and Corporation Tax return preparation, £150–£350 for payroll if you take a salary, Companies House filing requirements, and potentially higher accountancy fees overall. Many small business owners find these costs exceed any savings unless their profit level is high enough to benefit from the tax efficiency of dividends.
At what income level does incorporating become tax efficient?
As a general guide, many accountants suggest incorporation becomes worth considering once profits regularly exceed roughly £40,000–£50,000 per year, where the combination of Corporation Tax and dividend tax can be lower than Income Tax and National Insurance as a sole trader. This varies significantly based on individual circumstances and changes to tax rates, so professional advice is essential before deciding.
Can I switch back from a limited company to sole trader later?
Yes, but it involves formally closing the company (through striking off or members' voluntary liquidation), which has its own costs and tax implications, including potential Capital Gains Tax on any value extracted. It is not a simple reversal, so the decision to incorporate should not be made lightly or purely as a temporary MTD workaround.
