Each service detail page covers what it includes, who it suits, typical cost, and the technical references your accountant will work from.

— Choose by situation

Where you are tells you which service to start with.

Most Harrow contractors don't need all six services on day one. The right starting bundle depends on your IR35 position, your turnover relative to the VAT threshold, and whether you are negotiating a new engagement or running steady-state. These three scenarios cover the majority of new matches we make — pick the closest fit, then add adjacent services as your situation changes.

01

You're inside IR35 on a major client

Determined inside IR35 by a Canary Wharf bank, NHS trust, or other end client under the off-payroll rules? PAYE is being deducted at source — but a contract review can confirm whether the SDS is correct, and IR35 compliance work covers the formal disagreement process if working practices actually support outside-IR35 status.

02

You're outside IR35 and extracting profit

Limited company, outside IR35, day rate generating six-figure turnover? The single highest-leverage decision is the salary/dividend/pension extraction mix — modelled annually, not at company setup. Add limited company accounts to keep statutory filings clean and Corporation Tax optimised.

03

You've crossed (or are about to cross) the VAT threshold

Hit £90,000 turnover or seeing a clear path to it within 12 months? VAT registration is mandatory once the threshold is breached. Quarterly returns under MTD plus a scheme-selection conversation (Flat Rate vs Standard) are the immediate priorities — alongside expense-claim hygiene that protects every legitimate Section 338 travel deduction.

— What you actually pay

Six services, one fee table.

Typical UK contractor accountancy fee ranges, last reviewed 2026. Fixed-fee monthly packages available. Covers IR35 compliance, limited company accounts, VAT returns, and self assessment. Transparent pricing with no hidden charges. Bundles usually price below the sum of standalone fees.

Per assessment
Status determination, contract review, supporting documentation
Annual service
Accounts preparation, Corporation Tax return, Companies House filing
Annual review
Salary-dividend optimisation, tax projections, extraction strategy
Annual service
Expense categorisation, receipt management, HMRC compliance
Per quarter
VAT return preparation, submission, payment calculations
Per contract
IR35 assessment, risk analysis, amendment recommendations

Final fees are confirmed by your matched accountant after a short scoping conversation — turnover, IR35 position, and any structural complexity (multiple companies, overseas income) move you up or down the range.

— Off-payroll working rules

All six services assume the post-April 2021 IR35 reform.

For contractors engaged by medium and large clients in the private sector, IR35 status is determined by the end client (not the contractor or intermediary) via a Status Determination Statement. Inside-IR35 SDSs trigger PAYE deductions at source. Every accountant in the network handles SDS review, the Regulation 22A client-led disagreement process, and the limited company tax planning that follows from either status — both inside and outside.

  • SDS review for inside-IR35 determinations
  • Reg 22A disagreement process (SI 2003/2682)
  • Section 338 ITEPA temporary-workplace travel rules
  • Salary/dividend/pension modelling for outside-IR35 contractors
  • Status protection through working-practice documentation

Common questions

Common questions about choosing the right service

Generalists handle most of what a contractor needs technically — but contractor specialists save you money in places generalists routinely miss. The off-payroll working rules (Chapter 10, ITEPA 2003), the Section 338 travel-expense logic for temporary workplaces, the salary/dividend/pension extraction modelling, and the timing of dividend declarations across tax years are all places where contractor-specific experience pays for itself many times over the price difference.

Frequently asked questions about contractor accountancy in Harrow

Harrow contractor accountants use comprehensive assessment tools to evaluate your working arrangements against HMRC's off-payroll working rules. They consider factors like control, substitution rights, and mutuality of obligation specific to your contracts. Many Harrow contractors work with City firms, so local accountants understand both the contracting landscape and HMRC's recent focus on these arrangements.
