Best time to form a Limited Company

If you’re starting out as a contractor, or perhaps you’re already a freelancer and changing the way you work, you may be wondering “When is the best time to set up a limited company?”

We’re often asked whether forming at certain times of year, i.e. in line with the tax year, would save tax and simplify calculations for accounting purposes. Financially speaking, the short answer is that there is no optimum time of year, but here we answer some commonly asked questions to explore the factors you should consider to ensure the time is right for you, potentially maximising your tax efficiency along the way.

What do I need first: a Contract or a Limited Company?

While this can seem like a chicken and egg situation, your company needs to exist before it can enter into a contract with an end client to provide services. You can, of course, discuss and negotiate a contract before the company has been formed, but the limited company must exist before it can become the contracting party.

For this reason, most people we speak to who have already been in discussions with potential clients need their formation completed as soon as possible, in order to finalise their contract. Providing you have all the necessary details, online company formations are usually processed quickly, so when you’re ready to hit that button it’s all systems go!

If you’ve researched the different ways of working and feel this is the right avenue for you, then there’s no time like the present.

Does my formation date affect my accounting deadlines?

As a director of a limited company there are certain obligations you’ll need to fulfil, including submitting annual company accounts and Corporation Tax returns. Your annual accounts will cover your company’s financial year, which will normally run over a 12-month period after the first year.

The month in which you form your company determines its initial accounting reference date. This will usually be the last day of the month in which the first anniversary of the company’s incorporation falls. As a result, your first set of accounts will usually cover a period slightly longer than 12 months.

Let’s use Bob as our example:

Bob sets up his company on 15th October 2025, so his company year-end is 31st October 2026. Bob’s first annual company accounts will cover the period 15th October 2025 to 31st October 2026 and must be filed by 15th July 2027. Going forwards, subsequent accounting periods would normally run from 1st November to 31st October the following year.

It is worth noting that a Corporation Tax accounting period cannot be longer than 12 months. Where your first company accounts cover more than 12 months, you will therefore normally need to submit two Corporation Tax returns covering that first set of accounts.

Some people prefer their company financial year end to run in line with the April tax year. This is just for their own personal preference and is by no means a necessity. If this is the case for you, there’s no need to wait until April to set up your company. It is possible to change your year end, but to ensure clean and simple reporting and records it is not recommended to keep changing this.

Does the month I form a company affect the level of income tax I pay?

As the level of Income Tax you pay is based upon your income, be it through salary, or a mix of salary and salary and dividends, it’s not your company formation date that influences this, but more so the date on which you start receiving income from your company.

What matters is how much taxable income you have already received during the tax year, which ends on 5th April. Any dividends taken from the company before 5th April will fall into that tax year and, depending on your other income, could fall into a higher tax band. You should discuss the tax implications with your accountant to ensure you’re aware of the most tax-efficient time to draw dividends from the company.

If taking further dividends would push some of your income into a higher tax band, and you do not need the money immediately, one option may be to leave the funds in the company until the new tax year starts, when the relevant tax bands and allowances reset. Whether this is appropriate will depend on your individual circumstances.

I’m working as a sole trader, is there a point I’d be better off with a Limited Company?

Many start-ups initially choose the sole trader route with a view to changing to a limited company further down the line once profits grow. Tax efficiency can be one reason for incorporating, but there is no single profit level at which a limited company automatically becomes more tax-efficient.

The best option will depend on factors including your profits, how much money you need to withdraw from the business, your other income, pension contributions and the additional costs and responsibilities involved in running a limited company.
