Worth knowing
Rules that come up in this work
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
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
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.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
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 questions from Brentford Lock
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.
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 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.
