Do not mix your personal finances with the business: this mistake costs more than it looks

You stop knowing whether the business works

This is the expensive one, and the one nobody counts. If the same account pays the supplier and the family shop, the result at the end of the month is not the result of the business: it is the result of your life. A good month and a quiet month at home look the same as a bad month and an expensive one.

You cannot price, you cannot decide whether to hire, and you cannot tell whether a line of work is worth keeping, because you have never seen its real numbers on their own.

You cannot prove which expenses are the company's

An expense is deductible when it belongs to the business and you can show it. Paid from a personal account, mixed in among groceries and petrol, it is on you to prove the link afterwards — and “it was for work” is not proof.

In practice what happens is simpler and worse: the expense is left out so as not to open the discussion. You end up paying more tax than you owe for a reason that has nothing to do with tax.

The day somebody else has to look at it

A bank studying a loan. A buyer looking at the company. A new partner. An auditor. All of them ask the same thing: let me see the business on its own.

If it has never existed on its own, the answer is months of untangling, and whoever is on the other side draws their own conclusion about how the company is run while they wait. That conclusion costs more than the untangling.

And the one worth asking your lawyer about

Setting up a company puts a line between the company's assets and yours. Paying the company's things from your account, and yours from the company's, blurs that line in writing, month after month, in the only record that will be read if it is ever questioned.

We are not lawyers and this is not legal advice. It is worth knowing that the accounting record is what gets looked at, and that it is built one transfer at a time.

Separating it is cheaper than it sounds

1. One bank account for the business and one for you. Nothing else changes. This single step solves most of it.
2. Pay yourself. A fixed amount, on a fixed date, from the company account to yours. What you take out stops being an untraceable withdrawal and becomes a decision with a figure.
3. One card each. Not for control: so that nobody has to remember, months later, what that charge was.

What to do with what you take out

Money you take for yourself is not a company expense, however it leaves the account. It is a withdrawal against what the company owes you or against its profit, and it has its own place in the accounts.

Treating it as an expense is what quietly turns a profitable year into a mediocre one on paper, and it is one of the most common things we find when we pick up a set of books.

And the mess that is already there?

Do not try to rebuild four years backwards. It costs a fortune, it is never finished, and almost nobody needs it.

Draw a line on a date: from here on, separated. What came before gets tidied only as far as it has to be — the open periods, what is still being reviewed, what someone is going to ask about. The rest stays as it is, and that is a legitimate decision as long as it is a decision and not a postponement.

Three questions

1. Does the business have a bank account that only the business uses?
2. Do you take a fixed amount on a fixed date, or whatever is there when you need it?
3. If someone asked you today what the business earned last month, could you answer without taking your own expenses out by hand?

Separating the accounts takes a morning at the bank. Living with them mixed costs a little every month, which is why it never looks urgent.

If you want to look at where the line should be drawn and what is worth tidying backwards, that is the conversation we have most often. Write to us and we will take a look.
