Canadian organizations that issue tax slips need more than print production. They need accurate data processing, secure document composition, controlled printing, proper matching, mailing, and delivery support before CRA and recipient deadlines.
Tax slips often contain sensitive personal, employment, investment, pension, trust, or non-resident income information. That means the process must be secure, accurate, timely, and auditable.
AIIM helps organizations manage tax slip composition, printing, mailing, and customer communication workflows across Canada.
What are tax slips?
Tax slips are information slips issued by employers, financial institutions, trustees, payers, administrators, government bodies, and other organizations to report income, deductions, benefits, investment income, pension income, trust allocations, or other tax-related information.
Common Canadian tax slips include:
- T4, Statement of Remuneration Paid
- T4A, Statement of Pension, Retirement, Annuity, and Other Income
- T4A-NR, Payments to Non-Residents for Services Provided in Canada
- T4RSP, Statement of RRSP Income
- T4RIF, Statement of Income from a Registered Retirement Income Fund
- T5, Statement of Investment Income
- T3, Statement of Trust Income Allocations and Designations
- T5008, Statement of Securities Transactions
- T5013, Statement of Partnership Income
- NR4, Statement of Amounts Paid or Credited to Non-Residents of Canada
- T5007, Statement of Benefits
- T2202, Tuition and Enrolment Certificate
- T4FHSA, First Home Savings Account Statement
Different organizations issue different slips depending on the income, account type, recipient, and reporting requirement.
Why tax slip production is complex
Tax slip production is complex because it combines sensitive data, regulatory deadlines, multiple slip types, recipient delivery, and CRA reporting requirements.
A tax slip program may include:
- Secure data intake
- Data cleansing and validation
- Slip composition
- Variable data printing
- Recipient copy production
- Insert matching
- Envelope inserting
- Canada Post preparation
- Reprints and amended slips
- Reporting and reconciliation
- Audit history
The risk is not just whether a slip prints correctly. The risk is whether the right slip reaches the right recipient, with the right data, by the right deadline.
What are the main CRA deadlines for tax slips?
Many common slips, including T4, T4A, T5, T5008, T4RSP, T4RIF, T5007, T2202, and T4FHSA information returns, are generally due by the last day of February following the calendar year to which the slips apply. CRA guidance also states that if the due date falls on a weekend or recognized public holiday, the return is generally considered on time if received or postmarked by the next business day.
T3 trust returns and related T3 slips are generally due no later than 90 days after the trust’s tax year-end. For most trusts with a December 31 year-end, this usually means a March 31 deadline.
NR4 slips and NR4 information returns are generally due on or before the last day of March after the calendar year to which the information return applies, or no later than 90 days after the end of the estate’s or trust’s tax year.
Organizations should always confirm current filing requirements directly with CRA or their tax advisor.
Do tax slips have to be filed electronically?
For many CRA information returns, electronic filing is required when filing more than five slips for a calendar year. CRA guidance notes that for returns filed after December 31, 2023, information returns must be filed electronically if more than five slips are filed.
This matters because tax slip programs are no longer only about printing and mailing. They often need to support both recipient delivery and CRA electronic filing workflows.
Which tax slips can AIIM help produce and mail?
AIIM can support tax slip composition, printing, and mailing workflows for many common Canadian slip programs, including:
T4 slips
T4 slips report employment remuneration paid by an employer to an employee during a calendar year. CRA describes the T4 as the Statement of Remuneration Paid.
AIIM can help employers and service providers produce and mail T4 recipient copies securely and accurately.
T4A slips
T4A slips are commonly used for pension, retirement, annuity, scholarship, RESP, and other income reporting. T4A slips and summaries are generally due by the last day of February following the calendar year to which the slips apply.
AIIM can support T4A composition, printing, inserting, and mailing for administrators and payers.
T5 slips
T5 slips report investment income such as interest and dividends. T5 information returns are generally due by the last day of February following the calendar year.
AIIM can support financial institutions, investment firms, credit unions, and other issuers with T5 recipient mailings.
T3 slips
T3 slips report trust income allocations and designations to beneficiaries. CRA states that trusts use the T3 slip to identify beneficiaries and report amounts such as income and credits designated to them.
AIIM can support T3 recipient slip production and mailing for trust companies, fund companies, administrators, and related organizations.
T5008 slips
T5008 slips report securities transactions. CRA guidance states that T5008 information returns and recipient slips are generally due by the last day of February following the calendar year.
AIIM can support T5008 composition, printing, and mailing where organizations need controlled, high-volume recipient delivery.
NR4 slips
NR4 slips report amounts paid or credited to non-residents of Canada. NR4 recipient slips are generally due by the last day of March following the calendar year, with special timing for estates or trusts.
AIIM can support secure NR4 print and mail workflows for organizations with non-resident recipient communications.
T5013 slips
T5013 slips report partnership income to partners. CRA’s T5013 guide covers the partnership information return and related T5013 slips and summary.
AIIM can support partnership slip production and mailing where recipient documents need to be composed, printed, inserted, and mailed accurately.
Why security matters for tax slip printing and mailing
Tax slips contain personal and financial information.
That may include names, addresses, social insurance numbers, account information, employment income, investment income, pension income, tax withheld, taxable benefits, trust allocations, or non-resident payments.
A secure tax slip workflow helps reduce the risk of:
- Wrong-recipient mailings
- Exposed personal information
- Duplicate slips
- Missing slips
- Data formatting errors
- Late recipient delivery
- Poor audit visibility
- Reprint confusion
- Customer service escalations
For tax slip programs, accuracy and confidentiality are not optional. They are central to trust.
What should organizations look for in a tax slip printing partner?
Organizations should look for a partner that can manage the full workflow, not just the printed output.
A strong tax slip partner should understand:
- Secure file transfer
- Data processing and validation
- Document composition
- CRA slip formats and recipient copy requirements
- Variable data printing
- Print and insert matching
- Canada Post preparation
- Reprints, amendments, and exception handling
