- What Books and Records Must be Kept by an Individual or a Business?
Every business needs to keep reliable, accurate bookkeeping records in order to
Books and records must be kept by every:
The records that must be kept include books of accounts and records which provide the ability to calculate taxes payable. Books and records must be supported by "source documents" which substantiate the amounts in the books of account. Canada Revenue Agency (CRA) indicates that supporting documents for the income tax return of an individual should be kept for six years, in case they select your return for review. They may request more documentation than official receipts as proof of deductions or credits claimed, including cancelled cheques or bank statements. For instance, for a tax return filed in April 2009 regarding the 2008 income tax return of an individual, the source documents must be kept until at least January 2015. However, it would be better to retain the documents until six years after the date on the notice of assessment or notice of reassessment.
Source documents include (but are not limited to) invoices for purchases and sales, deposit slips, cheques, contracts, and trade confirmations for investment purchases and sales. These books and records are used to prepare financial statements of the business, which previously had to be prepared according to generally accepted accounting principles (GAAP). Changes in accounting standards mean that now financial statements must be prepared according to International Financial Reporting Standards (IFRS) or Accounting Standards for Private Enterprises (ASPE).
For purposes of income tax, most books of accounts, records, and source documents have to be retained for a minimum of six years after the end of the last tax year to which they relate. In the case of records regarding capital purchases, including investment purchases, the last tax year to which they relate would be much later than the acquisition date. It would be the tax year in which a disposal of the capital property occurred, because the purchase records would be required to calculate the gain or loss on disposal. Thus, records regarding capital property should normally be kept until six years after the end of the tax year in which the capital property was sold.
Some books and records of the business of a person (other than a corporation) must be retained until six years after the tax year in which the business ceased. These books and records include, according to Income Tax Regulation 5800:
Some corporate records must be kept until two years after the day the corporation is dissolved. These records include:
The books and records may only be destroyed earlier than this with the permission of the Minister. This can be requested by filing CRA's form T137, Request for Destruction of Books and Records.
