FAQs on contractor accountants

Do I need a specialist contractor accountant?

You don’t have to use one, but contracting has its own rules, from IR35 to the way you take money out of your company. A specialist who works with contractors every day will keep you compliant and make sure you’re not paying more tax than you need to.

What is IR35 and how do you help?

IR35 decides whether HMRC treats you as genuinely self-employed or as an employee for tax. We review your contracts and working practices, explain where you stand, and document the reasoning, so an inside or outside determination doesn’t come as a surprise.

Should I use a limited company or an umbrella?

It depends on your contracts and how long you plan to keep contracting. A limited company is usually more tax-efficient for outside-IR35 work; an umbrella can be simpler for short or inside-IR35 roles. We’ll talk you through the take-home difference for your situation.

Do you use AI for contractor accounting?

Yes, for the routine work: categorising transactions, matching receipts and flagging anything unusual. A qualified UK accountant reviews and approves every figure before it’s filed. The automation adds speed; the responsibility for your numbers stays with a real person.

Will I get a dedicated contractor accountant?

Yes. You get a named contractor accountant who knows your company and your contracts. You deal with them directly rather than a general support queue, so you’re not starting from scratch on every call.

Can I switch to Sleek mid-contract?

Yes, at any time. We request professional clearance from your current accountant, move your records across and update HMRC. You carry on contracting while we handle the handover in the background.

How much does a contractor accountant cost?

From £75 a month, with a fixed quote before you commit and no hourly billing. What you pay depends on whether you’re VAT registered, run payroll and how much bookkeeping is involved.
