Tax Basics for Independent Consultants
A plain UK guide to consultant taxes: when to register for Self Assessment, what counts as income, expenses you can claim, and how to keep records that hold up.
In this article7 sections
Consultant taxes are simpler than most people fear, but only if you set things up properly from the start. If you earn money from consulting in the UK, including paid sessions on a platform, you are trading, and HMRC expects you to report that income once it passes a small allowance. This guide covers the basics for independent consultants: registering, what counts as income, what you can claim, and how to keep records. If you are just starting to earn money giving advice online, read this before your first payout, not after.
One note before we start. This is general guidance for UK-based consultants, not advice on your own situation. Rules change, and an accountant who knows your numbers will save you more than they cost.
When you need to tell HMRC
The UK has a trading allowance that lets you earn a modest amount from self-employment each tax year without reporting it. Once your gross trading income (before expenses) goes over that allowance, you must register for Self Assessment and file a tax return.
Two practical points:
- The allowance applies to gross income, not profit. If you earn more than the allowance and then spend half of it on software and training, you still need to register.
- It covers all your trading income together. Consulting sessions, a bit of freelance writing and a few paid workshops are added up as one figure.
The tax year runs from 6 April to 5 April. You register for Self Assessment after the end of the tax year in which you started trading, and the online return and payment are normally due by 31 January the following year. The current deadlines and thresholds are on GOV.UK's tax pages; check them rather than relying on a figure you half remember.
What counts as income
For a consultant, income is the money you earned for the work, not the money that happened to land in your bank account.
A worked example. In March you deliver eight paid sessions at £60 each. The platform credits £480 to your wallet, and you request a payout in April. Most sole traders using the default cash basis would record the income when the money is received, but if you are using traditional accounting you would record it when it was earned. Pick one method, apply it consistently, and tell your accountant which one you use.
Platform fees matter too. If a platform takes a fee before crediting your wallet, you have two options: record the gross amount as income and the fee as an expense, or record the net amount. Either is acceptable as long as your records show the full picture and you are consistent. The booking and payout history on the platform is your evidence, so download it regularly.
Expenses you can usually claim
You can deduct costs that are wholly and exclusively for the business. For an online consultant that commonly includes:
| Expense | Typical examples |
|---|---|
| Software and subscriptions | Scheduling, note-taking, accounting apps |
| Equipment | Webcam, microphone, headset, a share of a laptop |
| Working from home | A fixed simplified rate or a proportion of bills |
| Professional costs | Memberships, insurance, CPD courses related to your field |
| Platform and payment fees | Marketplace commission, card processing fees |
| Marketing | Website hosting, a domain, paid ads |
Costs with a personal element, such as a laptop you also use for Netflix, can be claimed in proportion to business use. Keep a short note of how you worked out the split. Training that teaches you a new trade is usually not deductible, while training that updates skills you already sell is.
Keeping records that survive a question
HMRC can ask to see your records, and you must keep them for several years after the filing deadline. You do not need fancy software, but you do need a system you will actually use.
A workable minimum:
- A separate bank account for consulting income and expenses, even if it is just a second current account.
- A monthly export of your platform earnings and payouts, saved as a PDF or CSV.
- A folder for receipts, photographed the day you get them.
- A simple spreadsheet with date, description, amount and category.
Reconcile the spreadsheet against the bank account once a month. Fifteen minutes a month beats fifteen hours in January.
Pricing with tax in mind
Consultant taxes also shape your pricing. New consultants often set a rate, then feel shocked when a chunk of it disappears to tax and National Insurance. The fix is to price knowing that the headline rate is not what you keep.
If you charge £80 for an hour, and you expect to pay roughly a quarter to a third of your profit in tax and National Insurance once you pass the personal allowance, then around £55 to £60 of that hour is yours. Build that into your rates from day one rather than discovering it later. Our guide to setting your consulting rates walks through the arithmetic, and if you plan to turn sessions into a proper business, starting a consulting business covers structure and registration in more depth.
Also set money aside as you go. A common habit is to move 25 to 30 per cent of every payout into a separate savings pot the day it arrives, so the January bill is already funded.
Sole trader or limited company?
Most independent consultants start as sole traders. It is quick to set up, Self Assessment is manageable, and you can change later. A limited company adds admin, filing duties and costs, and it only tends to make sense once profits are consistently high or a client requires it. Do not form a company because a forum told you to; get an accountant to run the numbers for your actual income.
When to get help
You should talk to an accountant if any of these apply: you earn consulting income alongside PAYE employment and want to understand how the two interact, you work with clients overseas, you are approaching the VAT registration threshold, or you are considering a company. HMRC's own guidance is the authoritative source, and an accountant can translate it into decisions.
Consultant taxes are not a reason to put off starting. Register when you need to, keep clean records, price with tax built in and book an accountant for the parts that depend on your numbers. Then you can concentrate on the part you are good at, which is helping people and getting paid to earn money giving advice online. If you have not already, create your free consultant profile and start building the earnings those records will track.
Frequently asked questions
Do I need to register with HMRC for a few consulting sessions a year?
Not necessarily. The UK trading allowance lets you earn a small amount of gross self-employed income each tax year without filing a return. Once your total trading income passes it, you must register for Self Assessment. Check the current figure on GOV.UK.
Can I claim the fee a consultation platform takes from my earnings?
Yes. Platform commission and payment processing fees are normal business costs. Either record your gross earnings as income and the fee as an expense, or record the net amount you received, and apply the same method every time.
Should I set up a limited company for consulting?
Most consultants start as sole traders because it is simpler and cheaper. A company only tends to pay off once profits are consistently high or a client insists on it. Ask an accountant to compare both options using your real figures.
