If you are an American citizen with gainful employment, the Internal Revenue Service (IRS) expects you to pay taxes. An effective way to prepare taxes is by using tax software. While there's numerous tax software on the market, UltraTax CS, a product of Thomson Reuters, stands out.

What is Ultratax CS Professional Tax Software?

UltraTax CS is one of the tax and asset management products in Thomson Reuters's CS professional suite. It is designed for large firms that handle up to 250 tax returns each year.

The software is highly automated and has time-saving tools to make you more productive. You can access a complete list of forms for filing local, federal, and state returns, including 1040, 1120, 1065, and 1041. UltraTax CS can serve as a stand-alone program or be used alongside other programs in the CS professional suite such as eSignature and planner CS.

You can also integrate UltraTax CS professional tax software with Onvio, cloud-based software for managing your firm remotely. Onvio helps you to customize your workflow, collaborate with clients and team members, share data over a secure platform, and go paperless.

Types of Ultratax CS Professional Tax Software

Features of Ultratax CS Professional Tax Software

UltraTax CS Professional tax software has powerful features for managing clients and preparing and filing tax returns. Let's discuss these features in detail.

Multiple-MonitorsMultiple Monitors

Tax preparers work with a lot of data from different taxpayers. However, toggling between screens to review documents from a single taxpayer is hectic. UltraTax CS takes care of this by allowing you to view forms, inputs, and more on up to four different monitors at the same time.

Instant-Prep-ChecklistInstant Prep Checklist

UltraTax CS has a checklist that instantly gathers the data you want to extract from your client's previous year's tax return. This helps you to start the new Tax Year on the right foot. Imagine that you're repeating this task manually for each client. It will become too monotonous and boring.

Easy Data SharingEasy Data Sharing

Linking 1120S, 1041, or 1065 returns manually t0 the 1040 return takes time. Therefore, UltraTax CS's new method of sharing data automatically links returns using their ID numbers.


UltraTax CS supports electronic filing as well as other tools that monitor the process. You can see the status of the return and whether it is accurate or not. This way, you won't make mistakes when filing returns for clients.

Multi-State ProcessingMulti-State Processing

If your clients are from the same state, filing their tax returns may not pose many problems. But when they are from different states, the process becomes complex.

UltraTax CS eliminates this complexity by providing an Apportionment grid for filing business returns and another grid for Schedule K-1 or C income from different states. With this feature, you can accept clients from different states and boost your revenue.

UltraTax-FeaturesUltraTax CS 2020 Features

The new features of UltraTax CS include the following:

Connect Background Services: With this feature, you can automatically download and update UltraTax CS Data Entry and Bar Code Scan utilities.

If your e-filed return was rejected, you can now get help from the Help & How-to Center to troubleshoot the problem.

UltraTax CS no longer offers the Recall Transmitted Returns feature starting from 2019. This is because the IRS has a new pattern of accepting e-filed tax returns. Although the feature still appears on the CS Connect dialog of 2018 and older software, it is disabled.

UltraTax-FeaturesUltraTax CS 2021 Features

The 2021 version of UltraTax CS comes with the following:

  • Idea Incubation for posting suggestions for product improvement and upvoting the ideas of other users.
  • UltraTax CS now integrates with SafeSend, a third-party tool for sending electronic copies of tax returns.
  • The B&D screen has new fields for virtual currency transaction statements.
  • You can import cryptocurrency statements from LukkaTax and Ledgible by Verady.
  • New forms have been added: 461, 7203, 8915F, and 9000
  • E-signature is now available for 1040X returns.

Benefits of Ultratax CS Tax Software

Here's why you should use UltraTax CS tax software:

No-More-Repetitive-TasksNo More Repetitive Tasks

Processing tax documents for clients involves a lot of redundant tasks. You have to create and duplicate data entries, making the work more difficult and time-consuming.

With UltraTax CS, you can easily get rid of all repetitive tasks through automated data entry. The software integrates with Onvio Firm Management, document management, and Workpapers CS to eliminate manual data entry processes. This way, you will complete returns faster and accurately.

Save-More-Do-MoreSave More & Do More

Generally, businesses that use on-premise software spend money on purchasing and maintaining IT infrastructure. However, UltraTax CS is cloud-based, which means you won't need to spend money on all of that stuff. You also won't bother about setting up an IT team to take care of the office server and other work tools. Since the aim of every business is to maximize profits while reducing operational costs, UltraTax CS can help you save more money.

Real-Time-CollaborationReal-Time Collaboration

A typical tax firm has various CPAs reviewing the documents of clients here and there. But the office server does not encourage collaboration. Your team can't see the changes you're making on documents, so you have to explain things to them over and over again, which is stressful. And not everyone grabs instructions at a go. So the back and forth should be expected even if you resort to sending emails.

UltraTax CS bridges this communication gap by encouraging collaboration both in and out of the office. You can share and receive files in real-time as well as work on projects with your team from any location.

It's post-pandemic and everyone is trying to figure out how to become more efficient in a virtual work environment. Therefore, with UltraTax CS tax software, you can comfortably work from home and still remain productive.
