Welcome to InHouse Tax Administration

Support for businesses facing HMRC enquiries

About Us

The landscape surrounding tax and in particular certain tax schemes, has changed dramatically over the last decade. Strategies which were once considered to work are now vigorously challenged by tax authorities.

If you have entered such a scheme, we can help with the enquiries you receive from HMRC.

Administration, Support & Resolution:

The strategic and administrative burden of implementing and managing modern tax planning models and dealing with HMRC means that specialist administration and support is often required.

Individuals who entered into arrangements many years ago can find themselves under pressure to provide relevant information and a high level of administrative requirements.

InHouse Tax offers a range of fixed fee and bespoke admin services to users of tax planning strategies in addition to the support provided by their accountant or financial representative.

  • HMRC Enquiry Support
  • Legal Assistance
  • Documentation, Audits & File Reviews
  • Risk Assessment
  • Work closely with your existing accountant
  • Help with Tribunal Preparation & Suppor
  • Negotiation of Penalties
  • Computations*
*If required, we can calculate and assess the correct amount of tax due

Our services

InHouse Tax offers a range of fixed fee and bespoke services to users of tax planning strategies in addition to the support provided by their accountant or financial representative.

Our help reduces the stress, time and emotional pressure of responding to HMRC enquiries.

In many cases, we can facilitate a resolution that works for both parties, so that clients can move on with their lives and replan their future, without fear of going through a tribunal.

HMRC Support

Day to day telephone and email support for taxpayers with or without ongoing HMRC enquiries, includes handling all HMRC formal and informal requests for information.


This includes an overview and basic risk assessment of historic steps taken and client documentation based on current tax legislation and anti-avoidance rules.


HMRC correspondence will be responded to where necessary and a full digital file made available to the taxpayer upon request.

Further Steps

Following our overview of historic planning and a risk assessment, further guidance will be issued detailing any actions required.


This will include gathering and producing any documentation required to enable us to respond back to HMRC.


The objective is to achieve a firm understanding of the nature of the planning and maintain a file of all relevant documentation to support on-going communication with HMRC, so that their enquiries are handled effectively.

Bespoke Consultancy Services

It is not uncommon for requirements to arise which fall outside of the usual day to day administration of frequently used tax arrangements.


For example, a taxpayer may receive an assessment, closure notice, follower notice, APN, be subject to tribunal action or be exposed to new
anti-avoidance legislation which could not be foreseen.


These potential events can force the taxpayer to make some complex decisions and weigh up the pros and cons of all options available.
