Accountants in Whins of Milton

A limited company juggles two regulators: Companies House wants accounts within nine months of year end, HMRC wants corporation tax paid at nine months and a day. Same starting point, different documents — and late filing penalties at Companies House escalate automatically and are rarely cancelled.

People stay with the wrong accountant for years because switching feels disruptive. In practice the profession has a standard handover process — clearance letters, copies of prior returns and working papers — and the new firm drives it, not you.

If you contract through your own limited company, IR35 asks whether you'd be an employee without it. For medium and large clients, the status decision is theirs; for small clients, it's still yours — and getting it wrong in either direction costs money.

Most HMRC letters are routine — a statement, a code change, a reminder. The rule is simple: never ignore one, and never panic over one. Forwarded to your accountant the day it arrives, almost every letter is a five-minute job.

Most self-employed people under-claim. Use of home, mileage at HMRC's approved rates, phone and broadband apportionment, trade subscriptions, training that updates existing skills — legitimate deductions left on the table add up to real tax overpaid year after year.

Crypto traders rack up hundreds of taxable events without noticing, because every swap counts as a disposal. Specialist software plus the pooling rules turns the mess into a number; guessing does not.

HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.

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.
