about us

AvanTax Filing Services is offered by ELM Computer Systems (the developers of AvanTax eForms) and provides secure and reliable online processing of Canadian tax slips; slip distribution and XML data filing services for organizations of any size.

From multi-national firms with tens of thousands of recipients to shops with two or three, we give each client the best tax filing service available.


Our mission is to provide you with the best Canadian tax slip processing services available. We will prepare your return in a timely manner, at reasonable cost and with a team of experts; each of whom has several decades of experience in Canadian tax slip preparation.


You'll never be just another invoice with us. We know that, no matter its size, the heart and soul of your business are the people who show up each day and contribute to its success. We'll work closely with your people to ensure your returns are filed correctly and quickly.


Our online data filing service is reliable and simple; once you upload your data to our secure client portal you're done! We'll prepare, email or print & mail your recipient slips; we'll submit your XML files to CRA and RQ; and we'll give you copies of all reports for your records.

We also process third-party returns and create individual, custom named slips suitable for download from corporate portals.


We prepare all of the tax slips and returns listed here; and we'll also take special requests!

How does AvanTax Filing Services compare to processing tax slips in-house? Our volume lets us reduce processing, printing and postage costs for our clients and our decades of experience in Canadian tax processing let us do the job right.

Our clients save money and reduce stress when they subcontract their data processing to us. Give yourself a break and let us do the same for you.


A shortened version of the T2200 has been released by Canada Reveue Agency to facilitate reporting expenses incurred while working from home because of COVID-19; AvanTax Filing Services has been updated to include the new T2200S form.

CRA has added four Other Information codes to the T4 to confirm employee Canadian Emergency Relief Benefit (CERB) eligibility. CRA Source.
