Worth knowing

Rules that come up in this work

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.

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.

Corporation Tax rates and marginal relief

Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.

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.

Director's loan accounts

Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.

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.

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.

Questions

Freelancer Accountants questions from Mortlake and Barnes Common

How do you handle irregular and overseas income?

Irregular income is normal for freelancers and the monthly summary shows the year-to-date position so lean months are planned for. Overseas clients are invoiced without UK VAT in most cases, and any foreign tax withheld can usually be credited against your UK liability. Both are handled within the package.

Do I need to register for VAT?

Only when your taxable turnover in any rolling 12 months exceeds £90,000, or voluntarily before that. Many freelancers with business clients register voluntarily to reclaim VAT on equipment; those with consumer clients usually wait. We monitor your rolling turnover and advise before the threshold is reached.

What is the annual-only option?

For £229 a year we prepare your year-end accounts and Self Assessment from the records you keep yourself, whether in software or a spreadsheet. It suits freelancers with modest transaction volumes who are organised. If the records arrive as a shoebox, the sole trader accounts shoebox fee applies instead.

Should I be a sole trader or a limited company?

At profits under roughly £30,000 to £40,000 a sole trader is simpler and the tax saving from a company is small after the extra compliance cost. Above that, or where clients prefer to contract with a company or liability is a concern, incorporation can make sense. Our free comparison tool gives a first view and the starter session a definitive one.

What does the £79 company package include?

Monthly bookkeeping, director payroll with RTI submissions, dividend paperwork, the annual statutory accounts and CT600 filed with Companies House and HMRC, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. Your personal Self Assessment is added at the published £129 if needed.

What does the £45 sole trader package include?

Monthly bookkeeping from your bank feed with receipts captured by phone, a monthly summary showing profit and the tax accruing, your Self Assessment with the self-employment pages prepared and filed, payments on account calculated, and deadline tracking. Software is in your name and billed to you separately.
