HMRC Registration UK —
All Your Tax Registrations, Completed Correctly
Complete HMRC registration service for UK businesses — Corporation Tax, PAYE, VAT, Self Assessment and Construction Industry Scheme. We register all applicable taxes correctly, obtain all reference numbers and become your HMRC agent for ongoing correspondence. ACCA qualified. Fixed fee.
HMRC Registration — Every Tax, Every Registration, Correctly
Every UK business has HMRC registration obligations — but which taxes you need to register for, when you must register and the penalties for late registration vary significantly. We assess your specific situation and complete every required registration, obtaining all reference numbers and establishing HMRC agent authority so we can deal with HMRC directly on your behalf from day one.
Corporation Tax — UK limited companies must notify HMRC of chargeability to Corporation Tax within 3 months of starting to trade. HMRC issues a Corporation Tax reference number (UTR) and sets up your CT online account. Companies that fail to notify face a failure-to-notify penalty of up to 30% of unpaid tax — in addition to interest on late payment.
PAYE — employers must register for PAYE with HMRC before making any payment to employees. HMRC issues an Employer Reference Number (ERN/PAYE reference) and Accounts Office Reference. These are needed to file RTI submissions on or before each pay date. We register new employers for PAYE and set up the payroll scheme correctly — including Employment Allowance eligibility assessment from day one.
VAT — compulsory registration when taxable turnover exceeds £90,000 in any rolling 12-month period (within 30 days). Voluntary registration is available below the threshold. Current HMRC processing time for VAT registrations is 30-40 working days — meaning early application is critical for businesses approaching the threshold. We track turnover for all clients and initiate VAT registration at the optimal time.

4 Costly Mistakes — And How We Prevent Them
Many new company directors are unaware of the 3-month CT registration requirement. HMRC may not automatically notify you — the obligation is on the company. Late registration creates a failure-to-notify penalty plus interest on any unpaid CT from the date trading started.
PAYE must be set up before making any payment to an employee or director taking salary. Paying wages before PAYE registration means RTI submissions cannot be filed on time — creating automatic HMRC penalties and a backlog of compliance work.
With HMRC’s current 30-40 working day VAT processing time, businesses that apply for VAT only after exceeding the threshold face a period where they are legally required to charge VAT but don’t have a VAT number. Apply at least 6-8 weeks before you expect to breach the threshold.
Without formal HMRC agent authority, we cannot act as your representative with HMRC — we cannot respond to correspondence, request information or make submissions on your behalf without going through you. Establishing agent authority from day one means HMRC contacts us directly, not you.
HMRC Registration — Your Questions Answered
A new UK limited company must register for: Corporation Tax (within 3 months of starting to trade), PAYE (before making any salary payment to directors or employees), and VAT (when taxable turnover exceeds £90,000 in a rolling 12-month period or voluntarily if beneficial). If the company works in construction, CIS contractor registration is also required. We assess all applicable registrations for every new company.
HMRC currently processes VAT registration applications in 30-40 working days — approximately 6-8 weeks. During this period, the business is legally required to charge VAT on sales above the threshold but doesn’t have a VAT number. We advise clients to apply for VAT registration at least 6-8 weeks before they expect to breach the £90,000 threshold to avoid this problem.
An Employer Reference Number (also called PAYE reference) is the unique identifier HMRC assigns to each employer’s PAYE scheme. It is used on all payroll correspondence with HMRC, on RTI submissions and on employees’ P45s and P60s. The ERN has the format NNN/AAAAAA (3-digit HMRC office code followed by a 6-character alphanumeric). We register new employers for PAYE and obtain the ERN before the first pay date.
Yes — most HMRC registrations can be completed online via HMRC’s Government Gateway. However, many businesses make errors in the registration process — particularly around start dates, accounting periods and scheme types — that create ongoing compliance problems. Having a professional accountant register on your behalf ensures all registrations are correct from the outset and that agent authority is established simultaneously.
HMRC agent authority (granted via a 64-8 form) allows your accountant to deal with HMRC directly on your behalf — accessing your HMRC records, responding to correspondence, making submissions and requesting information. Without agent authority, your accountant must go through you for every HMRC interaction. As your HMRC agent, we receive all HMRC correspondence directly, respond within 24 hours and protect your position without you needing to deal with HMRC directly.
