Accountants in Battlefield Lane

Inside-IR35 and outside-IR35 engagements need different setups — sometimes umbrella, sometimes the company, sometimes both across a year. Contractors who plan this per-engagement keep more and worry less.

The capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.

Selling online, freelancing on the side, renting out equipment — each can be a "trade" in HMRC's eyes once it's done with a profit motive. The good news: registering is straightforward, expenses become claimable, and done early it's a non-event.

Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most Battlefield Lane clients who come to us in January still file on time; the records just need to arrive before the last week.

The businesses that struggle with tax bills rarely have a tax problem; they have a timing problem. Knowing the bill in September instead of January — which filing early gives you for free — is the difference between planning and scrambling.

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.

The best salary-dividend mix moves with each year's thresholds and your other income. Setting it once in April — rather than guessing through the year — is one of the simplest pieces of planning a director can do.

The businesses that find January easy are the ones whose bookkeeping happened all year — automatically. Modern software matches bank transactions, files receipts photographed on a phone, and leaves nothing to reconstruct from memory in the new year.
