Sound familiar?
Still not sure what your limited company actually owes?
Contractors running through a limited company face a specific set of pressures that a generalist accountant tends to underestimate. The salary and dividend split needs revisiting each year as allowances change. IR35 status sits in the background, unreviewed. Deadlines for the CT600, confirmation statement, and director’s self assessment arrive at different points in the year, and keeping track of all three while billing clients is a reasonable amount to carry.
- ✕ No clear view of the most tax-efficient salary and dividend split this year
- ✕ IR35 exposure on current contracts unreviewed and undocumented
- ✕ Multiple compliance deadlines managed manually, with no systematic reminders

- ✓ Salary and dividend reviewed annually, with numbers explained before any decisions are made
- ✓ IR35 position assessed across your active contracts, documented and on file

Everything a contractor limited company needs
The full compliance picture for a contractor limited company, handled on a fixed monthly fee with no scope creep and no surprise invoices at year-end.
Year-End Accounts and Corporation Tax
Your statutory accounts and CT600 are prepared and filed on time, with your corporation tax liability confirmed well before the payment deadline. You will know what the company owes before HMRC sends anything your way. The confirmation statement is handled as part of the same package.
Included as standardDirector’s Tax Return and Dividend Planning
Your personal self assessment covers director’s income, dividends, and any other taxable income. Before year-end, the salary and dividend split is reviewed against current allowances so the company is structured as efficiently as possible. The numbers are explained before any decisions are made.
Included as standardIR35 Review and Contractor Compliance
IR35 exposure on your current and recent contracts is assessed and documented. If a contract has characteristics that could attract HMRC scrutiny, you will know about it and understand what, if anything, needs to change. Cloud bookkeeping via Xero or QuickBooks Online keeps your records current throughout the year.
Available as add-onConsistent results across different businesses

Why contractors choose us over a general practice
The difference is not just the services on the list. It is having an accountant who already understands how a contractor limited company works before the first conversation.
No explaining contractor structures from scratch
Dividend and salary optimisation, IR35 considerations, off-payroll working rules, CIS if you work in construction — these are familiar territory. You will not spend the first three calls providing background that any contractor accountant should already know. The conversation starts at the useful part.
Live numbers, not a year-end surprise
Certified in Xero and QuickBooks Online, Supreme Consulting keeps your bookkeeping current throughout the year. Your corporation tax liability is visible before it is due, not revealed after filing. That alone tends to remove the most common source of stress for contractors.
One fixed monthly fee, clearly scoped
The fee is agreed upfront and covers the services specified. No hourly rates that compound during busy periods, no additional invoices for routine correspondence. If scope changes, that conversation happens before any work is done, not after.
Up and running in four steps
The onboarding process is designed to be straightforward. Most contractors are fully set up within two weeks, with no disruption to their current operations.
A no-obligation discovery call
A short conversation to understand your current setup, your contracts, and what you need from an accountant. No preparation required on your part. You will leave the call knowing exactly what would be included and at what cost.
A clear, fixed-fee proposal
You receive a written proposal covering the exact scope of services, the monthly fee, and the timeline. No ambiguous language, no add-ons buried in the small print. If it does not make sense, ask and it gets clarified before you sign anything.
Cloud setup and records migration
Supreme Consulting handles the transition from your previous accountant or bookkeeping system. Records are migrated to Xero or QuickBooks Online, integrations are configured, and your previous accountant is contacted on your behalf for any outstanding files.
Ongoing, with considerably less to think about
Deadlines are tracked. Books are kept current. Tax planning happens before the year closes, not after. You get on with the work that actually generates revenue, and the compliance side of the limited company runs in the background as it should.

Answers to what contractors usually ask
Do you understand how contractor limited companies actually work, including IR35 and dividend planning?
Yes. Contractor limited companies have specific characteristics — the salary and dividend structure, off-payroll working rules, IR35 status across contracts, and the interplay between personal and corporate tax — that differ meaningfully from a standard owner-managed business. Stuart works directly with contractors and reviews these areas as a matter of course, not as an add-on conversation when something goes wrong.
What does a contractor limited company package cost and what is included?
Pricing is fixed and agreed before any work begins. A core limited company package covers year-end statutory accounts, the corporation tax return (CT600), and the confirmation statement. The director’s self assessment and ongoing bookkeeping are typically added as part of a monthly retainer. The exact figure depends on the size and complexity of your company. A free quote outlines the full scope and cost before you commit to anything.
My books are in a bit of a state. Is that a problem when switching?
It is common, and it is manageable. Catch-up bookkeeping is handled as part of the onboarding process, and the cost of bringing records up to date is quoted transparently before work starts. The previous accountant is contacted directly for any outstanding files or handover information, so you do not need to coordinate that yourself.
Am I locked in? What happens if I want to leave?
There is no long-term contract. If it is not working after three months, you leave with clean, up-to-date books and nothing further owed. The professional handover to a new accountant is handled properly, including providing all the records and filing history they will need. The aim is to earn the relationship by doing the work well, not to retain clients through contractual friction.
Can you help if my IR35 status is uncertain across multiple contracts?
IR35 reviews are available as part of the contractor service. Each contract is assessed on its own terms against the relevant status tests, and the outcome is documented. If any contract has characteristics that could draw scrutiny, the position is explained clearly and options are discussed. Having a documented review on file is considerably more useful than relying on a verbal opinion if questions arise later.
How far in advance will I know what corporation tax and personal tax I owe?
With current bookkeeping throughout the year, the corporation tax liability is visible well before the nine-month payment deadline. The director’s personal tax position is reviewed before the year closes, so the salary and dividend split can be adjusted if it is still possible to do so. The objective is that there are no material surprises when the final figures are filed.
