Outside-IR35 Limited Company Accounting: what you need to know
Running a limited company on outside-IR35 contracts is the most tax-efficient way to contract, but only when the numbers are kept current. The dividend rates moved on 6 April 2026 to 10.75% at basic rate, 35.75% at higher rate and 39.35% at additional rate, with the allowance at £500, so any salary-dividend split still built on the old 8.75% and 33.75% rates is leaking money. Corporation tax adds its own layer, with marginal relief tapering between £50,000 and £250,000 of profit.
We run the full compliance cycle for PSCs: statutory accounts and the CT600, director payroll, VAT, the confirmation statement and the director's Self Assessment, all under a fixed monthly fee agreed before engagement. What separates an IR35 specialist from a generalist is what sits around that cycle. Status is treated as a live accounting matter, with board minutes recording reviews, contracts kept on file, and the salary-dividend strategy stress-tested each year against the current rates rather than rolled forward by habit.
Sloppiness in a contractor company tends to surface at the worst moment: a director's loan left outstanding nine months and a day past year end triggers Section 455 tax at 35.75% on loans made on or after 6 April 2026, a missed VAT calculation locks a limited cost trader into the 16.5% flat rate when standard accounting would do better, and thin records make any later status question harder to answer. We quote a fixed monthly fee, set the structure up properly and keep the evidence trail building in the background.
What you get
Rates that are actually current
Your extraction strategy is rebuilt on the 2026/27 dividend and corporation tax figures, including marginal relief, not recycled from a pre-April template.
Status woven into the bookkeeping
Contracts, working-practice confirmations and review minutes are filed as part of routine service, so the outside position is documented continuously rather than reconstructed later.
One fixed fee, full cycle
Accounts, CT600, VAT, payroll, confirmation statement and Self Assessment under a single agreed monthly price, with the scope in writing before you commit.
Mixed contracts handled cleanly
If you run inside and outside engagements through the same company, the deemed-payment income and ordinary trading income are kept strictly separate in the books.
What's covered under outside-ir35 limited company accounting
We handle the full range of work that sits within outside-ir35 limited company accounting, including:
Salary and dividend planning
An extraction strategy built on the post-April 2026 dividend rates and your personal allowance position, reviewed annually rather than set once and forgotten.
Limited company year-end accounts and CT600
Statutory accounts filed at Companies House and the corporation tax return at HMRC, with marginal relief between £50,000 and £250,000 calculated rather than approximated.
Contractor VAT returns and scheme choice
Quarterly returns plus a genuine calculation of flat rate against standard accounting, since most consultancy PSCs are limited cost traders stuck at 16.5% on the flat rate.
Director payroll and pension contributions
A compliant single-director payroll and employer pension contributions paid from the company, one of the few reliefs untouched by the dividend rate rises.
Director's loan account management
Monitoring and clearing loan balances before the nine-months-and-a-day point, where Section 455 tax at 35.75% on loans made on or after 6 April 2026 falls due on whatever remains outstanding.
Mortgage and contractor references
Accountant's certificates and income references prepared from your accounts, in the formats contractor-friendly lenders ask for.
Who this is for
We look after limited company contractors such as:
- A developer leaving an umbrella for a first outside contract who needs incorporation, VAT registration and a payroll scheme set up in the right order.
- A management consultant on day rates that push company profit into the marginal relief band, where the timing of pension contributions and expenses genuinely moves the bill.
- A contractor whose current generalist accountant has never once asked to see a contract and who wants status treated as part of the service.
- A locum running both inside and outside engagements through one PSC whose books have started to blur the two income streams.
- An interim director with an untouched director's loan account approaching the nine-month Section 455 deadline who needs it resolved before the charge lands.
How an engagement works
Outline your company
Day rate, contract mix, VAT position and what your current accountant does or does not do. That is all the quote needs.
Fixed monthly fee quoted in 48 hours
We set out the full scope and a fixed monthly price before you sign anything, including what status support is bundled in.
Switching handled for you
We handle professional clearance from your old accountant and the authorisations with HMRC, so the handover costs you nothing but a signature.
We run your year
Accounts, CT600, VAT, payroll, confirmation statement and Self Assessment, with the salary-dividend strategy reviewed against the current rates each year.
