TTI worksheets are standard Microsoft Excel™ documents that can be run on any platform with a modern version of this popular software (many worksheets depend on Macros). TTI worksheets can be used the same way as any other documents – rename them, save them anywhere, and even build your own supporting formulas when needed.

We email you a private link to a Google Drive folder. This will provide the latest TTI package(s) in zip format. Once downloaded, the worksheets can then be extracted to your desktop, server, or other applications according to your needs.

As a new client, you’ll normally receive your TTI files within an hour or two after subscribing.

We release regular updates (every month or two) which include new worksheets, feature enhancements, and rate changes. When there are changes to tax rates from a federal or provincial budget, we aim to release a new set of worksheets within a week. TTI’s Forex worksheets and Investment Bookkeeping worksheets are updated weekly.

When an updated TTI Suite is available for download, you will receive an email notification. This email will describe the current or future updates and provide a download link to the new TTI Suite. Once downloaded, you can delete older versions of the TTI Suite – each package is a standalone collection with the latest version of every worksheet. We provide an “FYI” email for any other users in your office describing the updates.

The TTI Suite is used by professionals across Canada. Our clients include public accountants (sole proprietors through national firms), financial institutions, wealth management offices, lawyers, internal tax groups, and others in need of tax results.

We welcome your skepticism! Our product is built in Canada by professional accountants, and we pride ourselves on the level of quality we consistently deliver. The first thing many tax experts do is put us to the test with a tricky scenario. We invite you to do the same. Please contact us for a demo.

Yes! Quebec tax rates are supported in most TTI solutions including flagship Tax Planning solutions such as Personal Tax Scenario, Corporate Tax Scenario, Salary vs Dividend, Prescribed Loan, and more. Several popular TTI Tax Accounting worksheets such as Safe Income, Investment Bookkeeping, Forex, and many others can be used any client file regardless of provincial residency.

TTI worksheets are licensed according to the number of professional users. Each licensed user can download and use them on any device. We offer annual subscriptions. The anniversary of your subscription date will be used for annual billing.

A professional user is anyone who will be preparing new calculations, or revising existing calculations in any TTI Worksheet. This ordinarily includes staff, managers, partners, and executives involved in a workflow where our worksheets are used. Professional users specifically exclude administrative staff not involved with calculations.

Many practices across Canada purchase licences for everyone in their firm. With a diverse collection of worksheets, every staff member will find two or three worksheets that will assist with routine calculations to complex scenarios. These firms benefit from uniformity, time savings, and the ability to show the value of their recommendations. After 10 users, the marginal annual cost is only $150 per user. Of course, not all offices are the same. You have full flexibility to determine the right number of users for your firm.

TTI worksheets can only be used with an active subscription. However, they may be accessed on a read-only basis, such as for future reference. Please see TTI’s license agreement.

TTI worksheets require Microsoft Excel 2010 or later.

Most worksheets require the use of VBA (macros) to access all features. “Excel for Web” and Excel for Mac are not compatible with these requirements.

We use secure servers hosted in world-class data centres to package the TTI Suite. Your files are packaged and uploaded to a private Google Drive share over a secure channel. Your own connections are also encrypted, ensuring that you receive files from us with security end to end. Once you receive the TTI Suite, every aspect of your usage is under your own control. You store the worksheets on your own computers, servers, or applications. No information will be sent to us, so there are no privacy considerations introduced by using the TTI Suite. You can see our privacy policy here.

We provide you with a Zip file containing Microsoft Excel™ worksheets in binary format (.xlsb), supporting PDFs, and links to support resources. There are no programs to install, and there are no executable files.

The ability to import between TTI worksheets is available for several worksheets in TTI’s Tax Planning collection such as Personal Tax Scenario, Corporate Tax Scenario, and Salary vs Dividend.

In other cases, as Microsoft Excel is among the most widely supported formats available, any programs will allow you to interface with our worksheets. While this is feasible in most circumstances, TTI does not support input or output to third party programs. In ordinary use cases, the complexities and risks introduced with input/output outweigh the benefits. According to your needs, a tech-savvy individual can modify our worksheets to support functionality with other software. Most worksheets provide named cells to streamline programming done manually or by VBA.

Jay Goodis and Andrew Skujins co-founded TTI in 2011. Both Jay and Andrew worked in tax and had a passion for technology. To date, they’ve invested well over 25,000 hours in development to build the TTI Suite. There’s much more to come!

Probably! We design each worksheet to support a broad range of common situations. Even if you have an unusual situation, odds are that we can support it. To get the most out of each sheet, we recommend reviewing our detailed worksheet instructions. Of course, you can always get prompt answers to your questions through our support channels. If you have a great idea that we haven’t implemented, we can include it in a future version – many of our popular features were originally by request.

We are very responsive to client requests. We encourage you to email us with features or worksheets that would support your business. There are numerous features and worksheets that are a direct result of client requests.
