How it works

Contractor Accountants from New Denham, step by step

  1. Tell us your situation

    A short message or call about what you do and what needs filing. We ask the questions that determine the right package and nothing more.

  2. Fixed fee in writing

    You receive one price for the work, confirmed by email before anything starts. It does not change if the job takes longer than we expected.

  3. Send records, review the draft

    Records come by WhatsApp or email. We prepare the draft, explain the figures in plain English and answer your questions.

  4. We file, you get the receipts

    Once you approve and the fee is settled, we submit electronically and forward the HMRC or Companies House acknowledgement the same day.

Why IGI

Why New Denham businesses file with IGI

No hourly rate and no surprise invoice. New Denham clients know the fee for contractor accountants before they send a single document, and it stays fixed.

We work to the HMRC and Companies House calendar, not an appointment diary. Clients in New Denham get reminders at 60, 30 and 7 days before each date that applies to contractor accountants.

Online only, UK based. There is no office in New Denham to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Continuity matters in contractor accountants: the person who prepared last year's work for your New Denham business prepares this year's, and remembers what was agreed.

Plain English, with the numbers. Every draft for New Denham comes with a short explanation of what the figures mean and what, if anything, you should do about them.

You stay in control of contractor accountants: drafts go to New Denham clients first, with the figures explained, and nothing leaves us until you say so.

Worth knowing

Rules that come up in this work

Confirmation statements and identity verification

Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.

CIS deductions

CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.

The VAT registration threshold

The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.

Corporation Tax rates and marginal relief

Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.

Salary versus dividends

The salary-and-dividend split is the central planning decision for an owner-managed company. Salary costs employer National Insurance above £5,000 but is deductible; dividends are not deductible but attract lower personal rates and no National Insurance. The optimum changes each April with the thresholds and depends on the director's other income, so it should be set deliberately every year.

Director's loan accounts

A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.

The Self Assessment calendar

The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.

Questions

Contractor Accountants questions from New Denham

I am about to leave permanent employment to contract. Where do I start?

With the company formation and the first contract review. Our £99 formation-plus-registrations package sets up the company with Corporation Tax and PAYE registered; the IR35 review of your first engagement decides how the income will be taxed. Join the Essential package from the month you start invoicing.

Do I need business insurance?

Most client contracts require professional indemnity and public liability cover, and employer's liability is a legal requirement if the company employs anyone other than the director. Insurance is not something we sell, but we tell you what your contracts require and the premiums are deductible for Corporation Tax.

Can the company pay into my pension?

Yes, and it is one of the most efficient ways to extract value. Employer pension contributions are deductible for Corporation Tax, free of National Insurance and not taxed on you, up to the £60,000 annual allowance (tapered for very high earners). We include pension planning in the Complete package's annual call.

What happens between contracts?

The company continues and so do the filings, but we can reduce the salary and pause dividends. If you expect a long gap we discuss whether to keep the company trading, make it dormant or close it. The monthly fee continues while the company is active because the compliance does, but we review it with you if circumstances change.

My client has put me inside IR35. Should I still use my company?

It can still be worth it if you have other outside-IR35 work, but for a single inside-IR35 engagement an umbrella company or direct PAYE is often simpler and cheaper. We run the comparison for your specific numbers and tell you honestly, even if the answer is that you do not need us for that contract.

Can I claim travel and subsistence?

For engagements outside IR35, travel to a client site that is a temporary workplace is claimable, subject to the 24-month rule: once you know an engagement will exceed 24 months at the same site, it stops being temporary. Subsistence follows the travel. Inside-IR35 engagements lose these claims. We check each engagement.
