Contractor accountants
Contracting through a limited company is a particular way of working with its own accounting rhythm. The company invoices one or a few clients at a time, often through an agency, and the contractor extracts income as a mix of salary and dividends. Each year the company files statutory accounts and a Corporation Tax return; each month it runs payroll for the director and reports it to HMRC; each quarter, if VAT registered, it files a VAT return; and each January the director files a personal return showing the salary and dividends. The pieces have to agree, and the salary-and-dividend split has to be set deliberately and documented properly, because HMRC looks at contractor companies closely.

In detail
How contractor accountants works
Our packages reflect that rhythm. Essential at £75 a month covers the compliance every contractor company has: accounts, CT600, monthly director payroll with RTI, dividend vouchers and minutes, the confirmation statement and deadline tracking. Plus at £105 adds quarterly VAT returns and monthly bookkeeping from the bank feed, so the records are maintained rather than reconstructed. Complete at £125 adds the director's Self Assessment and an annual planning call covering salary level, dividend timing, pension contributions and the year ahead. The fees are fixed and published; there is no charge for questions during the year and no separate year-end bill.
IR35 is the question that sits over every engagement. The rules ask whether the contractor would be an employee of the client if the company did not exist, judged on control, substitution, mutuality of obligation and the overall picture of the working relationship. Since April 2021, medium and large private-sector clients and all public bodies make the determination themselves and, where inside, deduct tax and National Insurance before paying the company; for small clients the contractor remains responsible. An inside-IR35 determination changes the economics completely, and for a single such engagement an umbrella or direct PAYE arrangement is often better than running a company. Our £99 review looks at the contract and the actual working practices and gives a written opinion you can rely on and show to the client.
Taking money out of the company efficiently is the other recurring task. A salary around the National Insurance thresholds keeps the year qualifying for State Pension and is deductible for Corporation Tax; dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% depending on your band and can only be paid from distributable profits after tax, with a board minute and voucher each time. Employer pension contributions are deductible, free of National Insurance and untaxed on the director up to the annual allowance, which makes them the most efficient extraction route for contractors who do not need all the cash. We set the salary each April, check reserves before every dividend, produce the paperwork and keep it on file, because undocumented dividends are the first thing HMRC reclassifies in an enquiry.
Everything is handled online. Bank feeds supply the transactions, invoices and expense receipts come by WhatsApp or email, payslips and dividend paperwork are sent electronically, and accounts and returns go to you for approval before filing. Expenses are reviewed against the rules that matter for contractors, including the 24-month rule on temporary workplaces, the treatment of home office costs, equipment and software, and the lost claims where an engagement is inside IR35. Between contracts the salary can be reduced and dividends paused, and if a long gap is expected we discuss dormancy or closure honestly. For employees about to start contracting, the company formation with registrations and the first contract review are the two things to do before the first invoice.

From first message to filed
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.
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.
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.
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.
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
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
Late filing penalties
Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
Payments on account
If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.
Salary versus dividends
Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.
Questions
Contractor Accountants: your questions answered
What is in the £75 Essential package?
Annual statutory accounts and CT600 filed with Companies House and HMRC, monthly director payroll with RTI submissions, dividend vouchers and minutes, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. It suits contractors outside VAT or who prefer to do their own VAT and bookkeeping.
What do Plus and Complete add?
Plus at £105 adds quarterly VAT returns and monthly bookkeeping from your bank feed, so the records are kept for you. Complete at £125 adds the director's Self Assessment return and an annual tax planning call covering salary, dividends, pension and the year ahead. Most contractors inside VAT choose Plus or Complete.
How should I pay myself from the company?
The usual approach is a salary around the National Insurance thresholds, which keeps your State Pension record intact and is deductible for Corporation Tax, with the rest as dividends taxed at the dividend rates after the £500 allowance. The exact split depends on your other income and the company's profit, and we set it at the start of each tax year.
What is IR35 and does it affect me?
IR35 asks whether, but for the company, you would be an employee of your client. If a contract is inside IR35 the income is taxed like employment. Since 2021 medium and large private-sector clients make the determination and deduct tax at source; for small clients the contractor decides. We review contracts and working practices and give a written opinion for £99.
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.
How are dividends documented?
Each dividend needs a board minute approving it and a dividend voucher recording the date, amount and shareholder. The company must have sufficient distributable profits after tax at the time. We check the reserves before each dividend, produce the paperwork and keep it on file, because undocumented dividends are reclassified by HMRC as salary or loans.
What is the flat rate VAT scheme and should I use it?
For most contractors with low costs the limited-cost-trader rate of 16.5% removes any advantage of the flat rate scheme, and the standard scheme reclaiming input VAT on equipment and software is better. Contractors with significant qualifying costs may differ. We calculate both at registration and review annually.
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.
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.
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.
