Accountants in Clissold

Miss 31 January and the £100 fine is automatic; three months later daily penalties start. If you're behind on a return, the maths almost always favours filing quickly over waiting — penalties grow on a timetable, and HMRC charges interest either way.

Receipts win arguments. HMRC doesn't demand a shoebox of paper any more — photos in an app are fine — but every deduction needs evidence behind it. A ten-minute weekly habit beats a January archaeology dig, every time.

New companies often have a long first accounting period, which can mean two corporation tax returns for one set of accounts. It's normal, but it's exactly the kind of thing that's cheaper to get right first time than to unpick.

Payments on account catch people out because the first year effectively bills you one-and-a-half years of tax at once. Knowing that in advance changes how you save through the year — and if profits fall, we can apply to reduce the July payment rather than lending HMRC money interest-free.

Disposing of crypto — selling, swapping one coin for another, spending it — is a capital gains event, and staking or mining income is usually income. Exchanges share data with HMRC, so the tax position exists whether or not it's been calculated.

Subcontractors under the Construction Industry Scheme have 20% deducted at source — often more than their final tax bill once expenses and the personal allowance are counted. That's why CIS refunds are so common: the average claim is well into four figures, but only if the deduction statements are all gathered.

The best time to switch is after a filing, but it works at any point in the year. What matters is not letting a looming deadline stop you: a new firm can usually pick up an in-flight year faster than you'd think.

Every tax bill is predictable months in advance — which makes tax the most plannable cost a business has. A separate tax savings account, fed a fixed percentage of every sale, converts January from a crisis into a transfer.
