Question 1

Do I need a contractor accountant based in Reading?

Accepted Answer

No. We serve Reading and Thames Valley contractors entirely remotely, covering Bracknell, Slough, Maidenhead, Wokingham and the M4 corridor. IR35 contract reviews, status determination checks, limited-company accounts and self assessment are handled online with secure document sharing. There is no need for a local office or in-person meetings, and specialist IT-contractor and IR35 expertise matters far more than a Reading postcode.

Question 2

I am an IT contractor for a large Thames Valley tech client. Am I inside IR35?

Accepted Answer

Off-payroll Chapter 10 applies because the client is a large multinational, so they issue the status determination statement and the fee-payer operates PAYE if you are inside. Whether you are genuinely inside or outside depends on the working practices, not the contract wording. Where a client dictates your methodology, hours, sprint priorities and tooling, the control test points inside, and a long embedded engagement filling a permanent-style role raises mutuality of obligation. A genuine, unfettered right of substitution points outside, but only if it is real. We review the contract and the actual working practices before you sign and at each renewal.

Question 3

My large tech client issued a blanket inside determination after April 2021. Can I challenge it?

Accepted Answer

Yes. A status determination statement must be reached with reasonable care for your specific engagement. Many Thames Valley technology clients moved categories of roles inside IR35 after April 2021 without individual assessment, which can be a failure of reasonable care. You have a client-led disagreement process and the client must respond within 45 days, either confirming the determination with reasons or issuing a new one. We review the SDS, your contract and your working practices and support the disagreement where the inside finding does not hold up.

Question 4

Is a limited company still worth it for a Reading IT contractor in 2026/27?

Accepted Answer

For genuinely outside-IR35 work, usually yes. Dividend rates rose to 10.75% and 35.75% on 6 April 2026, narrowing the incorporation advantage, but a limited company still beats umbrella PAYE for most outside engagements once you use the salary and dividend mix and an employer pension contribution. The pension route is National-Insurance-free and corporation-tax-deductible, which is a large lever on Thames Valley day rates. For inside-IR35 work an umbrella is often simpler. We model both with your real figures.

Question 5

What expenses can a Reading contractor claim under IR35?

Accepted Answer

For outside-IR35 work through your limited company the usual business expenses apply: accountancy fees, professional indemnity insurance, equipment and software, an employer pension contribution (the biggest lever), and business travel to a temporary workplace at 55p per mile for the first 10,000 miles from 6 April 2026, subject to the 24-month rule. For inside-IR35 engagements home-to-client travel is generally not deductible and the 5% expenses allowance is abolished under Chapter 10, so the focus shifts to pension contributions. We set the mix correctly for each engagement.
