Accountants for contractors
Contracting through a limited company is still the most tax-efficient way to work outside IR35 — and a compliance minefield inside it. A contractor accountant keeps both halves straight: the company run properly (accounts, VAT on the flat rate where it still wins, payroll for your salary), and the IR35 position of each contract understood before you sign, not after HMRC asks.
How we handle it
Fixed monthly fees cover the full company cycle plus your personal return, with take-home modelled per contract: day rate in, real money out, inside vs outside compared honestly. When a client forces inside-IR35 or umbrella working, we re-run the numbers so the decision is informed rather than resigned.

Terms you'll meet along the way
Statutory accounts
The formal year-end accounts every company must file at Companies House — publicly visible, prepared to FRS standards.
FRS 105 / FRS 102 1A
The two accounting standards small UK companies use: FRS 105 for micro-entities (minimal disclosure), FRS 102 1A for small companies (fuller picture).
CT600
The corporation tax return filed with HMRC alongside a tax computation — due 12 months after year end, though the tax is due at 9 months and a day.
Accounting reference date
Your company's official year-end date, set at incorporation (changeable within limits). Accounts are due 9 months after it.
RTI
Real Time Information — the rule that HMRC must receive a payroll submission on or before every payday, not at year end.
Auto-enrolment
The legal duty to enrol eligible staff into a workplace pension and contribute. Applies from your first employee, with The Pensions Regulator watching.
P60 / P45
The annual summary each employee gets after 5 April (P60), and the leaving statement when someone departs (P45).
Making Tax Digital (MTD)
HMRC's regime requiring digital records and software-filed returns — long mandatory for VAT, arriving for Income Tax from April 2026.
Accountants for contractors: your questions answered
What does IR35 actually turn on?
Whether you'd be an employee if the company wasn't in the middle — tested on substitution rights, control over how you work, and mutuality of obligation. Medium and large clients decide the status and issue a determination; you can and should challenge weak ones. We review contracts and working practices before signature, which is when the position is still shapeable.
What take-home should I expect from my day rate?
Outside IR35 through a company: typically 68–75% of contract value after all taxes, depending on rate, pension use and expenses. Inside IR35: broadly comparable to employment, 55–62%. We model your actual numbers rather than quoting the internet's — pension contributions swing the outcome more than most contractors expect.
Is the VAT flat rate scheme still worth it for contractors?
Since the limited-cost-trader rate of 16.5%, mostly no — the old easy win is gone for pure-labour contractors. But not universally: it depends on your recoverable costs. It's a two-minute annual check we run by default, because the wrong answer leaks money quietly.
How does IR35 affect me?
If a contract is 'inside IR35', tax is broadly like employment; outside, you keep the company's flexibility on salary and dividends. Since the off-payroll rules, medium and large clients determine status — but the risk and planning still land on you. We review contracts and working practices so you know where each engagement stands.
What's the most tax-efficient way to pay myself?
Typically a modest salary (keeping NI credits) plus dividends from post-tax profits, reviewed each April as thresholds move. It depends on your other income and pension plans — the review is included in every package.
My company hasn't traded — do I still need to file?
Yes. Even dormant companies must file accounts at Companies House and usually a confirmation statement. Our dormant package (£99) handles it all so you avoid penalties for a company that isn't even trading.
Which accounting standard will my accounts use?
Most small companies file micro-entity accounts under FRS 105 or small-company accounts under FRS 102 Section 1A. We pick the right one for your size and circumstances — it affects what's disclosed publicly at Companies House, and we'll explain the trade-offs.
I'm the only employee of my company — do I need payroll?
If you pay yourself a salary, yes — you need a PAYE scheme and RTI submissions even for one person. Director-only payroll is our most popular package at £25/mo, and we set the salary at the most tax-efficient level for you.
What is auto-enrolment and does it apply to me?
Every employer must assess staff for a workplace pension and enrol eligible employees. Even if your only staff member is you as director, you have duties to declare. We handle assessments, letters and declarations as part of the service.
When do I have to register for VAT?
When your taxable turnover in any rolling 12-month period passes £90,000 — a rolling test, not your accounting year, and the most common way businesses get caught out. We monitor it for bookkeeping clients automatically.
Which VAT scheme is best for me?
It depends on your margins and customers. The flat-rate scheme suits some service businesses; cash accounting helps if customers pay slowly; standard suits most. We'll compare them for your numbers before registering you.
What does the £129 fee include?
Preparation and online filing of your full SA100 return, including the supplementary pages your situation needs. If your return is more complex — rental income, capital gains — the packages above show the fixed price, and we confirm it in writing before starting.
I've missed the deadline — can you still help?
Yes. Late returns are common and fixable: we prepare and file the outstanding return quickly, and where there's a reasonable excuse we help you appeal penalties. The sooner it's filed, the sooner the penalties stop growing.
