Go Limited - Tax Essentials for Limited Companies: What You Need to Know to Stay Compliant
Once you’ve decided to set up a limited company for contracting, you’ll likely want to jump straight into things. You’ll want to start being your own boss and begin reaping the rewards, including making the most of tax benefits, as well as flexibility. As a limited company contractor, tax works in a slightly different way than you were employed, and to make sure that you stay compliant, you need to do your research and understand how to make the most of your contracting status.
This is where we come in. At Go Limited, we know all there is to know about staying compliant and we’re here to help. Read on this article to learn how to stay compliant and tax-efficient as a contractor.
Everything You Need to know About Limited Company Tax
Whether you’re transitioning from PAYE employment for the very first time or you’re a sole trader who’s setting up a limited company, you need to understand how limited company tax really works. It's different to how PAYE and sole trader tax works, and staying compliant relies on you knowing as much as possible about the process. If you’re a sole trader, you pay income tax and National Insurance contributions (NICs) based on your profits, and you do this via Self Assessment. If you’re an employee and you’re paid via the PAYE system, you have tax and NICs automatically deducted from your salary. It’s a relatively simple process, but it’s not always the most tax-efficient way of handling things.
As a limited company contractor, you pay corporation tax on limited company profits, and then you pay income tax and NICs on any salary and dividends that you take. This structure allows greater control over how profits are used and how tax is paid. You benefit from tax-efficiency - especially if you opt to pay yourself as a combination of salary and dividends - and limited liability, which means your personal assets are protected. Of course, these benefits only happen if you stay compliant, which is non-negotiable.
The Importance of Staying Tax Compliant as a Contractor
If you’ve decided to set up a limited company because you want the freedom of being your own boss, you’re in luck, as that’s exactly what happens. There’s no one to answer to, and you have complete control over how your business is run. However, there’s also a legal responsibility for you to manage your business correctly, including meeting all of your tax obligations.
If you don’t, you could be faced with financial penalties and stressful audits. Unsurprisingly, HMRC imposes fines for late filings, inaccurate returns or unpaid taxes. In fact, even minor delays can incur daily interest charges on anything that’s overdue.
There’s also a risk of investigations and audits if you’re not compliant. HMRC may conduct an inquiry into your financial records, which can be intrusive, time-consuming and expensive to resolve. Though many of HMRC’s investigations are random, you don’t want to give them a reason to deep dive into your finances.
Staying Compliant: Your Responsibilities as a Limited Company Contractor
As a limited company contractor, staying compliant means filing annual accounts and a confirmation statement with Companies House, submitting tax returns and paying your bill on time, and keeping accurate financial records. Being organised and proactive when it comes to limited company tax is key to avoiding compliance issues that can drain your time, profits and professional image. You have a responsibility to be compliant, and failing to do so isn’t an option.
Don’t Forget About Limited Company Tax Deductions
As a limited company director, you’re bound to have expenses. This is the case regardless of the work you do, the clients you work with or the professional services you provide. A number of your business expenses are likely to be tax deductible, which is one of the biggest tax advantages of running a limited company. You can claim business-related expenses that reduce your taxable profit, keeping more money in your pocket, without compromising compliance.
What Are Limited Company Tax Deductions?
Tax deductions, otherwise known as allowable expenses, are costs your business incurs as part of the day-to-day running of things. As long as they are exclusively used for business purposes, they’re likely to be tax deductible. These costs can be subtracted from your income before calculating how much tax you owe. By reducing your net profit, you reduce your tax liability, whilst staying compliant.
Reducing Tax Using Allowable Expenses for a Limited Company
To stay compliant with limited company tax, it's essential to claim only legitimate, justifiable limited company expenses. What you can claim will depend on the work you do, and what you spend, but some of the most commonly claimed expenses include:
- Home Office Costs - If you work from home, you can claim a portion of your home running costs. This includes electricity, heating and rent. HMRC also offers a simplified flat rate method, giving you a set amount to claim based on how many hours you work per month.
- Travel and Subsistence - If you travel for business, you might be able to claim some of your travel and subsistence costs. You can claim for business-related travel - including fuel, train fares parking - but not your regular commute. Meals while working away from your usual base may also be allowable.
- Professional Services - A lot of limited company contractors use professional services, and these are often allowable expenses. Fees for accountants, solicitors and consultants who support your business are included.
- Training and Development - Courses and certifications that are directly related to your current business can be claimed, but training for a new trade or profession usually can't.
- Equipment and Software - Most contractors rely heavily on equipment and software, and you can use these to reduce your tax liability. Computers, printers and licensed software used exclusively for work can be included.
How to Stay Compliant When Claiming Tax Deductible Expenses
If you plan to claim expenses as a limited company contractor, you need to make sure you do so in a tax compliant way. You don’t want to find yourself running into trouble further down the line, with HMRC asking for proof of what you’ve claimed, and you having no idea what you spent, when or why.
To stay compliant when you’re reducing your tax bill with allowable expenses, you need to maintain detailed records and invoices. It’s also a good idea to use separate business bank accounts for better tracking. Otherwise, it’s hard to know what’s been spent for business use, and what’s been spent on personal items. You need to avoid personal use of claimed items - or proportion costs accordingly if an expense falls into both the personal and business category - and be able to showcase how you calculate what you’re claiming. Retain receipts and proof of purpose for at least six years, in case HMRC investigate.
Making Your Limited Company Wages More Tax-Efficient
One of the biggest perks of running a limited company is the flexibility in how you pay yourself. You’re not limited by a solo salary; most directors adopt a pay strategy that uses salary and dividends for maximum tax-efficiency.

A Tax-Efficient Way to Pay Yourself
A salary is subject to income Tax and NICs, in line with the rates set for PAYE. But, dividends are distributions of post-tax profit, and these are taxed at lower rates. This means that by paying yourself a combination of salary and dividends, you reduce how much tax you need to pay.
By paying yourself a salary just above the NIC threshold - at the moment, that stands at £12,570 - you can maximise your personal tax-free allowance, make qualifying contributions to state pension, and minimise NICs. Then, you can draw dividends from your remaining profits, which will be taxed at a much lower rate. Remember, misuse of dividends - such as drawing money when your company isn’t profitable - can lead to compliance issues and HMRC penalties, so make sure everything is above board.
Staying Compliant Using Accountancy Services for a Limited Company
Though it’s possible to manage your own books and tax compliance, the complexity of limited company tax means most contractors benefit hugely from using professional accountants. They understand the rules, thresholds and tax-efficiency opportunities that are open to you, giving you the confidence that your records are complete, legal and ready to be audited. Working with a limited company accountant also helps you to avoid costly errors in tax calculations or late filings. You can focus on running your business, whilst they handle tax compliance. Even the most experienced business owners can benefit from having a professional eye on their finances, especially during year-end or tax return season.
Tax compliance is not just about avoiding fines, it’s about running your business responsibly and making the most of the tax advantages available to you as a limited company contractor. At Go Limited, we believe that by understanding how tax works - something we can help you with - claiming legitimate expenses and using a smart payment structure, you can strike the perfect balance between being compliant, organised and tax-efficient.
