Record Retention Guidelines:

Books and record retention requirements are important to your business because the records are used in determining your tax liabilities. YOU are responsible and bear the burden of proof in a tax audit … even if you hired a bookkeeper to do your books and a tax professional to prepare your return.

Who Must Keep Business Records?

Section 230 of the Income Tax Act requires books and records be kept in a format that allows assessment and payment of taxes. The Excise Tax Act, Employment Insurance and Canada Pension Plan legislation also have this requirement. Who must keep these records

  • any person who carries on a business in Canada;
  • any person or business who is required to pay or collect government taxes which includes GST, PST, and payroll source deductions;
  • any person or business required to file an income tax or GST return;
  • not for profit organizations

What Business Records Must Be Kept?

YOU must keep all records and supporting documents. Following is a general list of what must be kept:

Records generally refer to the organized method of documenting and summarizing accountingand financial information. This would include:

  • financial statements;
  • ledgers and journals – computerized or manual;
  • log and appointment books;
  • spreadsheets and working papers;
  • tax reports and records;
  • your Business Journal; and
  • other documents that support your claims.

When supporting documents are requested, it usually is a reference to source documents. Source documents are the original documents which prove the transaction occurred. Examples of this are:

  • bank statements, cancelled cheques and deposit slips;
  • sales invoices and receipts, cash register tapes, purchase orders;
  • credit card statements and all business purchase receipts;
  • legal and government correspondence;
  • any other documents and correspondence including e-mails.

If you are claiming the GST/HST input tax credits (ITCs), the detailed information required to support your claim is very specific.

How Must Business Records Be Kept?

How must you keep your records? Your records must be kept at your place of business or residence. They may not be kept outside of Canada, even if electronic access is available in Canada … unless you receive CRA permission. They must meet this criteria:

  • be complete and reliable;
  • be in paper format or electronic format (but you must ensure they are accessible and readable even if technology changes);
  • provide correct information to assist in meeting your tax obligations and entitlements
  • be supported by source documents (discussed above); and
  • include other documents (described under records above).

If you have more than one business, you must keep separate records for each business. It is also interesting to note that you must retain computerized or electronic files in a readable format … even if you have printouts of the records.

How Long Must Business Records Be Kept?

The general rule for record retention is records must be kept for six years from the end of the tax year which they are referring … or as long as CRA has informed you (usually by registered letter).

The tax year is the calendar year for taxpayers and unincorporated businesses and the fiscal period for corporations.

Some records and supporting documents that must be kept indefinitely are:

  • acquisition and disposal of property;
  • share registry;
  • historical information that would have an impact on the sale, liquidation, or wind-up of the business;

Some situations have different record retention requirements:

  • corporations – two years from dissolution (mergers and amalgamations are considered to be a continuation of the business);
  • late filed returns must be kept six years from the date the return is filed;
  • notice of objections must be kept until the objection or appeal is over AND the later of the time for filing appeals has passed or the normal six year period.
  • charities and political donation receipts and specified records – generally two years from the end of the calendar year they relate but verify this with CRA.

Early Destruction of Business Records

Records may be destroyed early if permission is received from CRA and any other relevant authority. File T137 Request for Destruction of Records with CRA. Early destruction without permission may lead to prosecution.

Pay attention to these record retention requirements and remember to factor in all the new regulations pertaining to privacy … where keeping too much information and for too long puts you at risk … not to mention the costs related to storing of the records.
