Will incorporating save me tax?

Sometimes, and less often than the general advice suggests for this trade. Losing the mileage and home working flat rates is a real cost, and the main advantage only pays if you can leave profit in the company rather than drawing it all.

Can you just form the company for me?

We can, but we will run the comparison first. Forming a company for someone the numbers say should stay a sole trader is not a service worth selling.

What extra filing comes with a company?

Annual accounts and a confirmation statement at Companies House, a Corporation Tax return, usually payroll filings for the director, and your own self assessment as well.

Are the company's figures public?

Yes. Accounts filed at Companies House are on the public record, which a sole trader's are not.

Limited Company Formation for Trainers

Forming the company is the easy part and it is not the part worth paying for. The work is deciding whether it is right for your numbers, and then running the extra filing afterwards.

The comparison itself is set out on the sole trader or limited company guide. This page is the engagement.

What Formation Involves

Incorporation at Companies House, the share structure, registered office, director and person of significant control filings, registering the company for Corporation Tax, and setting up payroll for the director's salary where that is part of the plan.

Then the ongoing obligations that arrive with it: annual accounts and a confirmation statement at Companies House, a Corporation Tax return, payroll filings, and your own self assessment on top.

Where Incorporating Goes Wrong

The most common error in this trade is incorporating without pricing in the loss of simplified expenses. Limited companies cannot use them, so the 55p mileage flat rate and the monthly home working rate both go. For a trainer covering serious mileage between clients that can swallow the tax saving on its own.

The second is incorporating while taking every pound out to live on. The structural advantage of a company is being able to leave profit in it, and if you cannot, most of the benefit does not arrive.

The third is the admin. It is not difficult, it is relentless, and the deadlines are separate from the ones you are used to.

How the Switch Runs

We run your actual figures both ways first, including the flat rates you would lose and the extra filing cost, and show you the comparison before anything is formed. If it does not pay, that is the answer and there is no charge for reaching it.

If it does, we handle the incorporation, the registrations and the transfer of the trade, and set the payroll and records up so the first company year end is not a scramble.

Fees for Company Formation

A fixed fee for the comparison and the incorporation, and a separate monthly fee for the company's ongoing accounts, Corporation Tax and payroll, both agreed in writing up front.

The comparison is worth buying on its own even if the answer is no. It is a great deal cheaper than incorporating and unwinding it.
