Do I Need to Register as Self-Employed to Be a VA in the UK?

Yes - if you're working as a virtual assistant in the UK and earning money from it, you need to register as self-employed with HMRC. There's no minimum income threshold for registration. Even if you're only earning a few hundred pounds a month alongside other work, you're legally required to register and file a Self Assessment tax return.

This sounds intimidating, but it's genuinely straightforward. Here's everything you need to know.

How to register

You register as self-employed through the HMRC website at gov.uk. The process takes about 10-15 minutes and requires your National Insurance number, your personal details, and a description of your business activity (something like "virtual assistant services" or "remote administrative support").

You should register as soon as you start working - technically, you need to register by 5 October in your business's second tax year, but there's no reason to wait. Register early and you'll have your Unique Taxpayer Reference (UTR) number ready when you need it.

Once registered, you'll need to file a Self Assessment tax return each year. The tax year runs from 6 April to 5 April, and the filing deadline is 31 January (for online returns) following the end of the tax year. So for the tax year ending April 2027, you'd need to file by 31 January 2028.

What tax will you pay?

As a self-employed VA, you'll pay income tax on your profits (your income minus your allowable business expenses). The rates for 2026/27 are 0% on the first £12,570 (your personal allowance), 20% on income from £12,571 to £50,270, and 40% on income above £50,270.

You'll also pay Class 2 National Insurance (a flat weekly rate of a few pounds) and Class 4 National Insurance (a percentage of your profits above a threshold). Your exact liability depends on how much you earn, but a good rule of thumb is to set aside 25-30% of your income for tax and National Insurance. Put this money in a separate savings account each month and you'll never be caught short.

Sole trader vs limited company

Most VAs start as sole traders because it's the simplest and cheapest option. There's no company registration, no annual accounts to file with Companies House, and no separation between your personal and business finances (legally speaking, you and your business are the same entity).

A limited company is a separate legal entity. It offers some advantages - primarily limited liability (your personal assets are protected if the business runs into trouble) and potential tax efficiency at higher income levels (because you can pay yourself a combination of salary and dividends). However, it comes with additional costs and admin: annual accounts, corporation tax returns, and usually an accountant to manage it all.

The general guidance is to stay as a sole trader until your profits consistently exceed £30,000-£40,000 per year, at which point the tax savings of a limited company may outweigh the additional costs and complexity. But this varies depending on your personal circumstances, so speak to an accountant before making the switch.

Do you need to register for VAT?

You only need to register for VAT if your turnover (total income, not profit) exceeds the VAT threshold, which is currently around £90,000 per year. Most VAs won't hit this level, especially in the early years.

If you do cross the threshold, you must register for VAT and start charging VAT on your invoices (currently 20%). You can also reclaim VAT on your business expenses. Some VAs voluntarily register for VAT before hitting the threshold - this can be beneficial if you have significant business expenses, but it adds complexity to your invoicing and bookkeeping.

For most VAs starting out, VAT registration is something to be aware of for the future rather than something you need to worry about now.

Keeping records

HMRC requires you to keep records of all your income and expenses for at least five years after the Self Assessment filing deadline. This means keeping copies of all your invoices, receipts for business expenses, bank statements showing business transactions, and any mileage records if you claim vehicle expenses.

A simple spreadsheet tracking income and expenses each month is enough to start with. As your business grows, consider using accounting software like FreeAgent, Xero, or QuickBooks to automate this and make your tax return painless.

The most important habit is to keep business and personal finances separate. Even though it's not legally required for sole traders, having a dedicated business bank account makes record-keeping dramatically easier and reduces the risk of missing deductible expenses.
