At any point in time, most directors of small limited companies either a) are owed money by their company or b) owe money to their company. The former is obviously a nicer place to be in general.
Money owed by a company to a director can accumulate for lots of reasons, including funds actually lent to the company to get it started, expenses or mileage not yet reimbursed, allowances for working from home and so on. Historically, many directors have been happy to let this Director’s Loan Account build up. If you don’t need the money in your own life right away, you might well be happy to leave it where it is rather than risk frittering it away!
That was all very well when interest rates were next to nothing. It didn’t matter too much whether you had the £30,000 or the company had the £30,000. Nobody was going to earn interest on it, so if its purpose was to be a rainy day fund, it was fine left in the company. Now, however, interest is a real thing! If the director gets her loan repaid to her and puts it in a savings account, she’ll probably earn interest of £100 a month. And some of that’s going to be tax-free, even if it’s not in an ISA.
The company could itself put the money in an interest-paying account of course (and, if the director is going to leave the money where it is, it probably should). But the company will pay corporation tax on all of the interest, and then when the director one day takes that extra money out of the company, she’ll pay tax too!
So, think of making savings work for you, and if you’ve money in your company that you can draw out tax-free, now may well be the time to do it.
