Freelancing around full-time employment

Whether you’re hoping to build a new business or just earn some extra income, freelancing around full-time employment can be a great option. It means you can test your ideas, or supplement your wages, without the risk of going all-in on self-employment. But there are some pitfalls to watch out for.

Freelancing around a full-time job or starting a side business can let you save for a more permanent switch in the future. You can work on your sales and marketing to build up a list of regular clients or customers, invest in start-up costs, and begin building a future without having to cover all of your personal costs straight away. Which can be hugely reassuring if you have family to support or significant financial commitments in place.

But you need to be aware of the legal, financial and personal implications. Otherwise, it could cause some serious issues for you, your family, and your career.

Financial responsibilities of freelancing on the side

Even if you’re only working for yourself part-time around your main job, you’ll be responsible for any additional tax and National Insurance payments required. 

Income tax rates are calculated on total earnings, so any self-employment profits will need to be declared alongside earnings from your employer. This will be done as part of your Self Assessment tax return each year.

In addition to tracking your income, expenses and profits, you’ll need to save some of your self-employed income to cover the additional tax cost. And you should also check whether any additional amounts will fall into a higher rate of Income Tax. If you’re already earning close to the basic rate limit for Income Tax, which is £37,700 at the time of writing, any taxable income above that will incur the higher rate of 40%. 

Anyone self-employed will usually pay Class 2 National Insurance if your profits are more than £11,908 per year, which is currently rated at £3.15 per week, and Class 4 National Insurance on profits above that figure (9.73% on profits between £11,909 and £50,270, then 2.73% on profits over £50,720 at the time of writing). This also applies if you’re the director of a limited company, but you may decide to take a larger amount of your income through dividends rather than a salary.

Managing the personal implications of more work

If you’re already working a full-time job and then taking on more work in your spare time, it can quickly have a negative impact on your personal and social life.

It’s tempting to try and use every available hour you have, especially when you’re excited to get started, or need to bring in extra income to cover your bills. But this carries a huge risk of burnout, especially if you don’t take into account the extra time needed for admin and other responsibilities when you work for yourself.

Setting boundaries for yourself is important. And communicating these to clients and customers will help ensure you’re not overpromising unrealistic expectations, and then under delivering. Taking client phone calls during your employed hours can quickly cause issues with your current employer, while ignoring them may lead to frustrated clients if you don’t explain you’re unavailable during specific hours.

Sometimes working flat out is unavoidable during emergencies, but it’s only sustainable in the extremely short term. Otherwise, you’ll soon feel the impact on your mental health, social life and personal relationships. If you want to build a sustainable freelancing business, it’s important to schedule time away from working, and learn how to manage stress to avoid it impacting on you, and those around you.

One big benefit of becoming self-employed alongside an existing job is that it can prove to partners, family and friends that you’re able to work for yourself, and that your business can be successful, before you decide to go all-in.

Having clear boundaries on your part-time career also makes it simpler to prioritise your full-time employment, which is likely to be the source of the majority of your income and benefits, especially in the early days.
