If you are running a marketing agency, a digital agency, or a creative agency as a sole trader or partnership, you have probably asked yourself whether incorporation makes sense. The question usually comes up around the £50,000 to £80,000 profit mark, when the tax savings on dividends start to outweigh the extra admin.

But the cost to incorporate an agency 2025/26 is not just the Companies House filing fee. There are professional fees, tax implications on transfer, and ongoing compliance costs that catch founders out. This article breaks down every pound you will spend and every week you will wait, so you can decide whether incorporation is worth it now.

Direct Costs of Incorporating an Agency in 2025/26

Let us start with the hard numbers. The fees you will pay to legally create your limited company are small, but the supporting costs are where the budget adds up.

Companies House Registration Fees

You can incorporate a company online for £50 using the standard service. That gets you registered within 24 to 48 hours in most cases. If you need it same-day, the premium service costs £100 and is usually processed within a few hours. For a straightforward agency incorporation, there is no reason to pay more than £50.

Some formation agents charge £100 to £300 for the same service, bundling in a registered address, a company seal, or digital banking introductions. You do not need any of that. Use the Companies House portal directly or ask your accountant to handle it. Most accountants charge a modest admin fee on top of the £50, typically £50 to £150, for filing the incorporation documents and registering for corporation tax at the same time.

Registered Office Address

If you work from home, you may not want your personal address on public record. A registered office address service costs between £30 and £100 per year. Your accountant may offer this as part of your monthly fee. It is a small cost, but one you should budget for annually.

Accountant Setup Fees

This is the biggest variable. If you already have an accountant, they will usually handle the incorporation as part of your onboarding. If you are switching from a sole trader return to a limited company, expect a one-off setup fee of £300 to £750. That covers:

  • Incorporation filing and company registration
  • Registering for corporation tax with HMRC
  • Setting up payroll for your director salary
  • Registering for VAT if your turnover exceeds £90,000
  • Setting up accounting software (Xero, QuickBooks, or FreeAgent)
  • Drafting your first set of shareholder agreements if you have multiple founders

At Agency Founder Finance, we typically charge a fixed setup fee that covers all of the above. We have seen other firms charge up to £1,500 for the same work, so shop around. But do not use the cheapest option if they do not understand agency-specific issues like IR35, retainer billing, or contractor status.

Ongoing Costs After Incorporation

The cost to incorporate an agency 2025/26 does not stop on day one. You need to factor in the recurring costs of running a limited company.

Accountancy Fees

A sole trader accountancy fee for a small agency is typically £100 to £200 per month. For a limited company, expect £250 to £500 per month. That covers your year-end accounts, corporation tax return (CT600), personal tax returns for directors, payroll, and VAT if applicable. Some firms charge a lower monthly fee and a larger year-end fee. We prefer a flat monthly fee so you know where you stand.

Payroll Software

You need RTI-compliant payroll software to pay your director salary. Most accountants include this in their monthly fee. If you run it yourself, software like Xero Payroll or MoneySoft costs £5 to £15 per month.

VAT Compliance

If your agency turnover is above £90,000, you must register for VAT. That adds a quarterly or monthly filing obligation. Most accountants include VAT returns in their monthly fee. If not, expect an extra £30 to £60 per quarter.

Dividend Administration

Paying yourself in dividends requires a dividend voucher for each payment and a board minute if you are following best practice. Your accountant can handle this, but if you do it yourself, the cost is your time. Do not skip the paperwork, HMRC can challenge dividend payments if the records are poor.

Tax Costs of Incorporating

This is where founders get caught out. Transferring your agency from a sole trade to a limited company is not a tax-free event in all cases.

Capital Gains on Asset Transfer

When you incorporate, you are transferring your business assets (goodwill, equipment, client contracts) to the new company in exchange for shares. HMRC treats this as a disposal for capital gains tax purposes. If your agency has significant goodwill value, say you have a strong brand and a retainer book worth £200,000, you could face a capital gains bill on incorporation.

There is relief available. Incorporation relief under Section 162 TCGA 1992 allows you to defer the gain if you receive shares in the new company. But you must claim it correctly on your tax return. If you miss it, you pay CGT at 10% or 20% on the gain now, rather than when you sell the shares later.

Stamp Duty on Property

If your agency owns property (unlikely for most, but possible if you have a studio or office), transferring it to the limited company triggers stamp duty land tax. This can be substantial. Most agency founders leave property outside the company structure for this reason.

VAT on Transfer

Transferring a going concern (TOGC) rules mean you can usually transfer the business without triggering a VAT charge. But you must meet specific conditions. Your accountant should confirm this before you file anything.

Timeline: From Decision to Trading as a Limited Company

How long does the whole process take? Here is a realistic timeline based on our experience working with digital agencies and creative agencies.

Week 1: Planning and Advice

You meet with your accountant to review your current profit, projected growth, and personal tax position. We run the numbers to confirm incorporation makes financial sense. We also check whether you have any contracts that need re-assigning or client consent before transferring. This takes one to two hours.

Week 2: Incorporation Filing

Your accountant files the incorporation with Companies House. You receive your certificate of incorporation, company number, and memorandum and articles of association. If you use the standard £50 service, this takes 24 to 48 hours. We also register the company for corporation tax with HMRC at the same time.

Week 3: Bank Account and HMRC Registrations

You open a business bank account. This can take one to two weeks depending on the bank. We recommend applying as soon as you have your company number. While you wait, we register for PAYE (employer reference) and VAT if needed. HMRC typically issues the VAT number within 10 working days.

Week 4: Transfer Assets and Start Trading

You sign the incorporation agreement (sometimes called a Section 162 election) to transfer assets to the company. You issue shares to yourself and any co-founders. You set up your director salary at £12,570 per year to stay within the primary NI threshold. You start billing clients from the limited company from this date.

Total time from decision to trading: four to six weeks. If you need it faster, you can compress this to two weeks by using the premium Companies House service and a bank that opens accounts within 48 hours (like Tide, Starling, or Monese).

When Does Incorporation Make Financial Sense?

The cost to incorporate an agency 2025/26 is typically £500 to £2,000 in the first year, including setup fees and the increase in accountancy fees. The ongoing annual cost is roughly £1,500 to £3,000 more than running as a sole trader.

You need to save at least that much in tax to make it worthwhile. For most agency founders, the tipping point is around £50,000 to £60,000 of taxable profit. Below that, the tax savings from dividends versus self-employed income are eaten up by the extra compliance costs. Above that, the savings are real.

Here is a worked example. A web design agency with £120,000 profit. As a sole trader, the owner pays roughly £38,000 in income tax and NI. As a limited company paying a £12,570 salary and the rest in dividends, the total tax bill is around £28,000. That is a saving of £10,000 per year, which more than covers the extra costs.

What About IR35?

If your agency works with contractors, IR35 affects your decision. As a limited company, you become responsible for issuing Status Determination Statements (SDS) to contractors. If you get it wrong, HMRC can pursue you for unpaid tax and NI. This is a real risk for agencies that rely heavily on freelancers.

We cover this in detail on our contractors and IR35 blog. But the short version is: if your agency model depends on contractors, factor in the cost of IR35 compliance (typically £200 to £500 per year for software and advice) before incorporating.

Incorporating with Co-Founders

If you have multiple founders, the cost and timeline increase slightly. You need a shareholder agreement drafted by a solicitor. That costs £500 to £2,000 depending on complexity. You also need to agree on share classes, dividend rights, and exit provisions before incorporation. Do not skip this. We have seen too many agency partnerships break down because the paperwork was vague.

Your accountant can recommend a solicitor who understands agency structures. We work with several who charge fixed fees for straightforward shareholder agreements.

Should You Incorporate Now or Wait?

If your profit is below £50,000, wait. The cost to incorporate an agency 2025/26 is not justified by the tax savings. Focus on growing revenue and margin first.

If your profit is above £60,000 and you plan to reinvest in growth, incorporate now. The corporation tax rate of 19% on profits up to £50,000 (or 25% above £250,000) is lower than your personal income tax rate on sole trader profits. And the ability to retain profits in the company gives you flexibility for hiring, equipment, or acquisitions.

If you are approaching an exit, selling the agency in the next two to three years, incorporation is essential. You need the shares to qualify for Business Asset Disposal Relief (14% CGT on the gain for 2025/26, rising to 18% from April 2026). You cannot claim BADR as a sole trader. Read our growth and exit blog for more on that.

Final Checklist Before You Incorporate

  • Confirm your profit is above £50,000 and likely to stay there
  • Check whether your current contracts allow assignment to a limited company
  • Decide on your director salary (standard: £12,570)
  • Choose your accounting software and accountant before you file
  • Open a business bank account as soon as you have your company number
  • Register for VAT if turnover exceeds £90,000
  • Claim incorporation relief on asset transfers if applicable
  • Draft a shareholder agreement if you have co-founders

If your situation is more complex, for example, you have overseas clients, you are based in the UAE, or you have a property in the business, speak to an accountant before filing. Our team at Agency Founder Finance handles these scenarios regularly. We are ICAEW qualified accountants who work exclusively with agency founders, so we know the specific questions to ask.
