With Microsoft Dynamics GP set to reach end of support in 2029, many businesses are debating if they should stay on GP or migrate to the cloud. While your Dynamics GP system might continue to function after 2029, there are many risks of delaying migration. For many businesses, especially those in regulated industries, running an unsupported system is not simply a technical challenge – it’s also a tax compliance and security liability.
In this blog post, we go over the compliance risks of staying on Dynamics GP post the December 2029 end-of-support deadline.
What does Dynamics GP end-of-support really mean?
Once Dynamics GP support ends in December 2029, Microsoft will stop providing product enhancements, tax updates, and technical support. Security updates/patches, if needed, will be made available until April 30, 2031.
Many users ask if they can continue to run Dynamics GP after 2029. The answer is yes – your system may still work in the short term. But if you need a bug fix—or a security vulnerability pops up—you’ll be on your own.
For many businesses, Dynamics GP also plays a key role in managing tax filings and regulatory reporting.
Once support ends, GP will no longer:
- Reflect updated IRS rules, tax codes, or payroll tax rates
- Generate compatible reports for electronic filing systems
- Support secure audit trails or documentation required during a tax audit
Maybe none of this sounds like a big deal today. But fast-forward a few years, and suddenly you might find yourself dealing with auditors asking why your business is using unpatched software or facing penalties from the IRS for incorrect filings.
Compliance risks of staying on Dynamics GP after end of support in 2029
Tax compliance risks
Once Dynamics GP reaches end of support in 2029, Microsoft will no longer release year-end updates in December. These updates are essential because they introduce changes to ACA reporting, form 1095-C, W-2, and more, to align Dynamics GP’s U.S. payroll module with filing requirements. Without these year-end updates, your Dynamics GP system may not reflect current IRS rules, tax codes, or required reporting formats—leading to inaccurate filings, rejected submissions, or penalties.
Further, as your Dynamics GP system gets outdated, it might become incompatible with modern e-filing systems. This can lead to filing errors if you have to rely on manual data entry, or delays in filing if your system generates reports in the incorrect format.
Security compliance risks
Without security patches for your Dynamics GP system, your business risks falling out of compliance with regulatory standards like PCI-DSS, NIST, GLBA, ISO-27001, and HIPAA.
These data privacy laws, standards, and regulations require that applicable businesses implement reasonable policies and procedures to safeguard confidential customer data or personally identifiable information (PII). Running unsupported software makes it challenging to demonstrate that appropriate measures are in place to protect sensitive data.
Since unsupported software does not receive vendor-backed security patches for known vulnerabilities, they are a prime target for cyberattacks like ransomware, data theft, and more. If your business uses outdated software like Dynamics GP and your confidential customer or patient data is exposed in a breach, regulators will likely cite this as a negligence. This can open the door to fines, penalties, and reputational damage.
