Monitoring tax due dates can be challenging. With so many moving parts, even the most clear-headed accounting professionals can become confused and overwhelmed. On top of that, your firm also needs to plan for every worst-case scenario—say, a client passes away unexpectedly or a member of your firm is unable to work for an extended period of time. That's why it is important to have a due date monitoring software in place.

As an accounting firm, you must have systems in place that notify you of upcoming deadlines—even for other accountants’ work—or you could miss an important filing date and be subject to penalties from the IRS (or even get sued by your client). 

To make your practice run as smoothly and efficiently as possible, it’s essential to invest in a due-date monitoring tool. Below are some of the most common due-date monitoring tools for accountants that can make the job easier. 


Many accounting firms rely on spreadsheet software, such as Microsoft Excel, to manage their due dates and other client data. However, spreadsheets are probably the least useful due date monitoring tool for several reasons. 

First, as returns, bills, and assessments roll in, due dates may change quickly, and the spreadsheet will need to be manually updated to reflect these changes when they arise, which can drain your team’s productivity and rob them of valuable billable hours that could be spent on client-facing work. 

Second, users will have to research and include dates for early payment discounts and installments, meaning they will need to continually verify the “best guess” Excel calendar with actual due dates as they become aware of them. Plus, managing versions, settings, and permissions for shared spreadsheets can be difficult. Even using cloud-based options like Google Sheets or Microsoft 360 can create bottlenecks in your workflow. 

For these reasons, modern accounting firms have largely moved away from spreadsheet due date monitoring in favor of digital methods that include cloud-based project and task management software. 

10 Essential Money Metrics for Accountants

Online Calendars

Online calendars such as Microsoft Outlook are easily shareable and can be accessed from anywhere. However, they do not provide as many benefits as due date monitoring software because users still have to track how much they filed the returns for and the value of each assessment.  

A solution like this really only addresses half the equation and doesn’t provide a full practice management solution. Plus, with any system that requires manual data entry, there is room for error—such as entering a deadline incorrectly or forgetting to add all the relevant parties to a calendar event. 

When you’re handling something as critical as tax deadlines, you want to rule out the possibility of even the simplest mistakes. 

Due date monitoring software 

Due date monitoring software, especially when built in to a practice management software, is by far the best option for accountants, who operate in a deadline-driven field.  

This software updates due dates automatically. That way, all users have to do is enter a search for deadlines in a selected time period for all the jurisdictions that apply.    

Integrated due-date monitoring software is highly beneficial because it’s much more than just a calendar or to-do list. It also helps accounting teams:   

Manage workflows    

A project dashboard can show you all the tasks that need to be done for various clients. You can create project templates to auto-populate for certain types of clients and then fill in pertinent details and due dates so nothing slips through the cracks. 

Send email notifications 

Add and assign tasks to specific team members from your dashboard and stay up to date with their progress with email notifications that are automatically sent whenever there are updates or a project is ready for review. 

Track time  

When you know how long each task takes, you know how much time you need to work on each project per day to make the due date. You’ll understand exactly how many clients you need to remain profitable and whether or not you have time to take on new ones. 

Tracking time with the right tool can also provide valuable insights into employee productivity so you can assess who’s doing well and who’s falling behind and make changes as needed. This process also enables you to see what your most efficient team members are doing and use that knowledge to help your whole team boost productivity.   

Invoice clients  

Stick to critical billing due dates with invoice software that speeds up non-billable tasks for you. Use recurring billing with online payments to charge clients automatically each month and batch invoicing to create invoices for multiple clients. 

Generate comprehensive reports  

When you’re managing several projects at one time, it can be difficult to keep up with all of the moving parts—that’s where comprehensive reporting comes in. With due-date management software, you can generate detailed workload reports for all of your deadlines to ensure you’re making progress and meeting your deadlines.
