Client Hub

The ultimate practice organiser.

Take a Trial

Introducing our award-winning
Client Hub software

TaxCalc Hub is a suite of powerful, complementary practice management tools that are designed to ensure you get the very best out of your TaxCalc software.

It is built around four core functions: clients, tasks, mail merge and reports. Each has been designed with SimpleStep® workflows, to guide you and your staff through comprehensive processes, quickly and efficiently.

There is no additional charge for TaxCalc Client Hub. We believe that it is fundamental to the smooth running of a practice and every TaxCalc customer should benefit from this type of software.


The heart of your practice

TaxCalc Client Hub acts primarily as a single source of client information, capturing as much as possible and then sharing this with the other applications in the TaxCalc suite.

The data entered is used to pre-populate sets of accounts, tax returns and VAT returns. Data all comes back from these sources, being made use of within mail merges and reports.

Click on the picture, left, to see how TaxCalc Client Hub integrates with other TaxCalc software.

Client communications

Send your clients letters, emails and tax questionnaires by using our powerful Mail Merge and Questionnaire functions.

Clients can be selected specifically or using a Data Mine, which interrogrates the database to find clients that meet specific criteria.

Manage and control

TaxCalc Client Hub features task and deadline management, so you can assign work to staff, track their progress and ensure client deadlines are met.

The software also features a dashboard of tax return production progress and a powerful reporting function, with pre-built reports to track progress in detail.

A scalable solution

All of TaxCalc's software products are built on a single platform. Installation is straightforward, with easy deployment and online licensing.

A no-cost server option is available, providing many benefits of centralised data storage such as shared access and a single backup.

Help is always on hand

We aim to make our software as easy to use as possible but for those times when you need us, you can be sure we're there. Our support is unlimited and provided at no extra charge.

And in January, when our customers need us the most, we extend our support capacity and hours more than anyone else. Our established team have both academic and practical accountancy experience, so you know that whatever your problem, we can find a solution.

Fully comprehensive, yet easy to use software

We believe that Practice Management software shouldn't be an expensive optional extra for your practice – it's fundamental to getting the best out of your TaxCalc software. That's why TaxCalc Client Hub comes free, as standard, with every TaxCalc software product.

Create and manage client records

As well as capturing name and contact information, TaxCalc Client Hub can be used to keep records on services charged, engagement status, AML events, notes and much more. And if you can't find a desired field, you can easily add your own.

Tasks, reminders and work tracking

Take control of the activity in your practice by creating and scheduling tasks for automatic assignment to staff, with deadline, reminders and completion progress. Accounts, tax and VAT work can be tracked according to any of a series of customisable task types and work statuses.

Mail Merge and Tax Questionnaire

Send bulk letters and emails via Microsoft Word. TaxCalc Client Hub comes complete with a library of standard engagement letters, written to the latest CCAB standards. Select and send clients a tax questionnaire to collect tax information in advance of starting their tax returns.


TaxCalc Client Hub features a wizard driven report engine, helping you to build reports based upon clients, tasks and work status.

The system comes with a number of pre-built reports to get you going quickly.

Data Mine

As more data is captured by your TaxCalc software, you'll want to do more with it. Data Mine can be found in Mail Merge, Tax Questionnaire and Report functions and helps target clients that fit specific criteria.

Data Mine can also be used to check and validate client data. For example, finding all clients without a UTR.

Client Dashboards

TaxCalc Client Hub features a tax return dashboard, with a customisable client list table, helping you to see at a glance how many tax returns you have outstanding and the progress of work through your practice.

Client records themselves feature a customisable and printable 'at a glance' view of your client's core information.

Integration by default

As the core of the TaxCalc suite of products, TaxCalc Client Hub integrates tightly and shares the data you entered with the other applications in the range.

TaxCalc Client Hub ties together related processes. For example, marking a client as being new to your firm can automatically create a 64-8 and engagement letter.

Other useful HMRC forms

TaxCalc Client Hub features a small library of additional HMRC forms:

  • Both online and offline 64-8
  • SA1 
  • FBI 2
  • SA303
  • CWF1
  • CT41G

Scalable server version at no extra cost

Gain the benefits of storing your data centrally with our no-cost server option.

Installation is incredibly straightforward, with easy deployment, online licensing and automatic configuration.

TaxCalc for all firms

We recognise that practices in the UK come in all shapes and sizes.
That's why we offer a wide range of Unlimited and smaller pre-built packages to suit your client base.

Whether you opt for your TaxCalc software to be supplied in standalone or server versions,
they both cost the same and come with free, unlimited support.


Suitable for startups and those working on their own:

  • TaxCalc's server software is designed to run over modest, lightweight hardware. You don't even need a dedicated server. In simple setups, you just need to bless one computer on your network with the database and TaxCalc takes care of the rest.
  • TaxCalc's software is optimised to run over a VPN, allowing you to connect from remote locations. Our CloudConnect service also allows you to connect from any location, providing superb performance and removes the need to run your own server or backups.

TaxCalc in action

We believe that Practice Management software shouldn't be an expensive optional extra for your practice -
it's fundamental to getting the best out of your TaxCalc software. That's why TaxCalc Client Hub comes free,
as standard, with every TaxCalc software product.

Your clients are accessed from the main Client screen.

You can customise the client table, showing columns of information (such as work status). Use the tax dashboard to keep track of tax return progress.

Whenever you open a client in TaxCalc Client Hub, you will see a summary of key information about them.

This screen can be customised on a per client basis and printed for your paper records.

Setting up tasks is easy with TaxCalc's wizard.

Tasks can also be scheduled from within the client's record and referenced with key dates, such as the accounting year end.

TaxCalc Client Hub is provided with a range of template letters, neatly organised by type.

You can easily add to the range of templates provided, each written to CCAB standards.

Help your clients to organise their records prior to starting their tax return by sending them a questionnaire.

New clients can be sent a blank questionnaire whilst existing clients can be based upon last year's return.

As well as using the Clients screen to keep on top of work progress, TaxCalc Client Hub features a comprehensive reporting function to create a variety of reports.
