Consultancy services

Consultants sell their expertise, often to several clients at once. Anewthing keeps the accounts, tax and VAT in order so that the business side takes as little of your time as possible.

Consultancy businesses range from a single specialist working through their own company to a firm with associates, employees and clients overseas. The accounting needs are similar at every size: clean records, accurate invoicing and VAT, accounts and tax returns filed on time, and advice before decisions are made rather than after.

Anewthing prepares the accounts and tax returns, runs payroll where there are employees, and advises on the questions consultants ask most often: how to pay yourself, whether to register for VAT and which scheme to use, how to treat expenses and home-working costs, and how to deal with clients in other countries.

Where you take on associates or subcontractors, or your clients ask about your employment status, Anewthing reviews the arrangements against the off-payroll working rules and helps you put the right contracts in place.

Common questions

Do I need to register for VAT as a consultant?

Registration is compulsory once your VAT-taxable turnover passes the threshold in a rolling 12-month period, and can be worthwhile earlier if your clients are VAT-registered businesses. Services supplied to business clients outside the UK are often outside the scope of UK VAT, which Anewthing can confirm for your situation.

How is a consultancy different from contracting for tax?

For tax the same rules apply: what matters is the working relationship with each client. Consultants with several clients and genuine business risk are usually clearly in business on their own account, but a long engagement with one client can still fall within the off-payroll working rules.
