Accountants for IR35 contractors

Limited company contractors working inside or outside the off-payroll rules.

• Who decides status: the end client for public sector and medium or large private sector engagements, the company itself for small private clients

• Status Determination Statements, the client-led disagreement process and keeping the evidence for each engagement

• Deemed payments and tax already deducted at source, so the same income is not taxed twice in the company

• The 5% allowance and expense position, which differ between inside and outside engagements

• Salary and dividend planning when only part of the year's income is inside the rules

Whatever the sector, the company must file accounts with Companies House nine months after the accounting reference date, file a CT600 within twelve months of the period end, pay corporation tax nine months and one day after the period end, and file a confirmation statement each year.

Once taxable turnover passes £90,000 in a rolling 12 months, VAT registration and Making Tax Digital filing follow. Employing anyone, including a director on a salary, brings PAYE, RTI reporting and auto-enrolment pensions.

Thresholds, rates and deadlines quoted here reflect the 2026/27 UK position. Check current GOV.UK guidance, or ask us, before you rely on them for your own company.

We agree the scope and monthly fee before starting, set up bookkeeping that fits how you invoice and buy, and send reminders ahead of every filing date.

You get plain answers to sector questions in normal language, and we say clearly when something needs specialist advice rather than guessing.
