Data security for tax and accounting firmsProtect your clients and your practice

Taking action to help you keep your clients safe

Cybercriminals are specifically targeting tax and accounting firms at increasing rates — and it's not just the big firms being targeted, but firms of all sizes.

In May of 2015, criminals used information obtained from social media and stole around 724,000 taxpayers' return data from the IRS's Get Transcript system. This is just one case — as cybercriminals become more advanced in their methods (from phishing scams to illegally accessing firm software and filing fraudulent tax forms), all tax and accounting firms must stay vigilant against threats and take action to keep their businesses and clients safe.

At Thomson Reuters, the security of your data and your clients' data is a top priority — and we're continuing to take steps to strengthen data security, help you protect your practice and comply with IRS security requirements. Working together, we can put safeguards in place to help you protect your clients and your firm.

Check out our fact sheet for important information about data security, and keep reading for actions you can take to help you stay safe against security threats.

Security requirements

License PIN update required

As part of our ongoing efforts to improve security for your data and your clients' data, every firm is issued a License PIN (Personal Identification Number), which you must enter when downloading your software licenses. By default, your License PIN is your firm's ZIP code.

You are required to update your License PIN so it does not match your ZIP code before you can download your software licenses. This helps prevent anyone who might have knowledge of the PIN (for example, a former employee, or any unauthorized person who knows your ZIP code) from downloading your software licenses without permission. Entering an invalid PIN — including your firm's ZIP code — will result in an error message that prevents you from downloading your licenses.

If you have not done so already, as the licensee for your CS Professional Suite programs, you must update your PIN. For full details, including the steps required to complete this process, see Managing your license PIN in our Help & How-To Center.

Your new License PIN takes effect immediately. You will now use this new PIN when you're ready to download your software licenses. Share your new License PIN only with staff members or IT professionals who need to download your software licenses via CS Connect.

As the Licensee for your firm, you must have your own CS Web account. For help creating your account, see New Licensee account in our Help & How-To Center.

IRS requirements for tax software

Beginning with tax year 2016, the IRS — working in partnership with tax software vendors and practitioners in the profession — put security requirements in place for all tax-related software for professionals. At Thomson Reuters, we believe that all data is important, so these changes were applied to all our software.

Here is a summary of the IRS requirements:

  1. Login requirements: Tax-related software for professionals needs to be protected by a login with certain password requirements.
  2. Password strength: As defined by the IRS, a strong password contains a minimum of eight characters with at least one uppercase letter, one lowercase letter, one number and one special character. The IRS also requires that preparers reset their passwords every 90 days.
  3. Timeout period: Applications must time out after 30 minutes of user inactivity and requires users to log back in using their credentials. However, while your access is suspended, the operation of the software is not, so the processes within the software will continue during the timeout.

For full details, see the CS Professional Suite application security overview topic in the Help & How-To Center.

Multi-factor authentication

As a leader in data security, Thomson Reuters can offer even more advanced security options for any firm that wants multi-factor authentication (additional identity verification for extra security) for CS Professional Suite (desktop), Virtual Office CS® and Software as a Service (SaaS).

We're pleased to introduce Thomson Reuters Authenticator, our new multi-factor mobile app, which provides industry standard authentication factors. We strongly advise that you enable multi-factor authentication to strengthen the security of both your firm and your clients' data. For details about implementing multi-factor authentication for your firm, see the Multi-factor authentication overview in our Help & How-To Center.
