Rebuilding Books From Bank Statements in Canada: T2125, T2, HST

Missing books do not cancel a filing duty. Rebuild each year from every account statement: sort deposits into customer payments and everything else, add cash never deposited, support expenses from statements and supplier records, and check GST/HST registration. A sole proprietor reports on a T2125; a corporation files a T2, not a T2125.

Do I still have to file every year if I have no books?

A missing set of books does not remove a filing duty. A corporation files a T2 for every tax year, including years with no tax payable (CRA: T2 guide). A sole proprietor may need a T1 (personal) return with a T2125 if tax is owing or a refund is wanted, if the CRA asked for a return, if self-employment earnings are high enough that CPP contributions are due, or for other listed reasons (CRA: do you have to file). A business registered for GST/HST files a return for every reporting period, including periods with no sales (CRA).

The CRA does not wait for a return. It can assess tax without one, leaves out voluntary deductions you may have been eligible for, and estimates business expenses from earlier filings (CRA: unfiled returns; Income Tax Act, section 152). A late return also carries a penalty that grows with the tax unpaid and the months late (Income Tax Act, section 162). For the penalty rules, filing order and relief, see unfiled personal returns and unfiled corporate returns.

A rebuild is not simple when several years are open, a corporation and its owner share accounts, cash never reached a bank, GST/HST applies or a CRA letter has arrived. The last section lists when to get help before filing. Gather first:

  • Every statement for every account the business touched, including personal and card accounts.
  • E-transfer histories, payment-processor or platform reports, and any slips customers issued, such as a T4A.
  • Invoices, contracts, quotes, booking calendars and client messages.
  • Prior returns, CRA notices, the business number and any GST/HST registration details.
  • For a corporation, the incorporation date and year-end.
  • For any statement you no longer have: a copy from each bank, card issuer and payment processor, closed accounts included. Customers can also resend invoices and payment confirmations.

Keep the records for an unfiled year. For income tax records, the retention period runs from the day the return is filed (Income Tax Act, section 230); see how long to keep business records.

What do the CRA's record rules require, and do bank statements count?

A business must keep records that let its tax be worked out, and the CRA says income records must show the date, amount and source of each receipt. It also tells businesses to keep duplicate deposit slips, bank statements and cancelled cheques. These show that money moved, not what it was for (CRA: business records; Income Tax Act, section 230).

Statements need partners. The CRA lists sales invoices, cash register tapes, receipts, bank deposit slips, fee statements and contracts as the documents that support income entries. GST/HST has its own duty to keep records that show the tax owed (Excise Tax Act, section 286). The CRA says not to send records with an income tax return, so keep them for the preparer and for any CRA request (CRA: business records).

Do I bring screenshots of the e-transfers?

Bring the bank's own statements and e-transfer history in electronic form first, and use screenshots only to fill gaps. The CRA's electronic-records bulletin says records that start out electronic must be kept in an electronically readable format (CRA: electronic record keeping). A bank's electronic statement is that original.

The bulletin does not mention screenshots. Its test for an image of a paper original is that the image carries the same information and is legible and readable. A screenshot that cuts off the date, amount or sender would not meet a test like that, and whether a screenshot suffices is not settled on the CRA's pages. Use one for what the statement does not show, such as a client's message, and keep the full statement beside it. For scanned or photographed paper, see scanned receipts for the CRA.

How do I turn bank statements and e-transfers into sales, month by month?

Label every deposit as a customer payment or something else, then total the customer payments by month. Only customer payments are sales.

  1. Put each account's statements in date order and start with the oldest year. Each opening balance should equal the previous closing balance; a mismatch means a missing statement.
  2. Download every account's transactions into one spreadsheet.
  3. Label each deposit using the table below.
  4. Match customer payments to invoices, contracts, messages or the sender's name. List what you cannot match for the owner to confirm.
  5. Total customer payments by month, then by tax year (for a corporation, to its own year-end). The GST/HST registration test is different: it counts by calendar quarter, when each sale became due or was paid if earlier (see the registration section).
  6. Check the sort: customer payments plus everything labelled not a sale must equal the deposits on the statements, month by month. A gap is a missing or mislabelled line.
DepositIs it a sale?
Customer payment by e-transfer, cheque or cardYes, at the gross price, once matched to an invoice or agreement. A processor's payout is net of its fee, so record the fee as an expense. A refundable security deposit is not GST/HST consideration until applied to the price (Excise Tax Act, section 168); see GST/HST on deposits and unpaid invoices and customer prepayments.
Tip from a customerYes. Self-employed people report tips on the T2125 (CRA).
Transfer from your own other accountNo. The money was counted where it first arrived, so every account must be in the set.
Money the owner puts in, or a loanNo. A contribution is not earned and a loan is debt.
Supplier refundNo. It reduces the original expense.
Tax refund or sale of personal propertyNo.
Family or friends sending personal moneyNo.

Treating every deposit as a sale overstates income. Leaving an account out does the opposite, because a transfer nets out only when both accounts are in the set. The CRA's own bank deposit analysis works this way: it removes loans, transfers, tax refunds and sales of personal assets, then asks the taxpayer to explain what is left (CRA audit manual).

Bank deposits show when money arrived, not when it was earned. Which year an unpaid invoice belongs in depends on the accounting method; see cash or accrual accounting. Platform payouts and US-dollar income have their own steps in rebuilding platform and US-dollar income. To match e-transfers to invoices from now on, see tracking e-transfer payments.

What about cash I took and never deposited, or a cash business with no documentation?

Cash from customers is income whether or not it reached a bank, so a rebuild adds an estimate you can explain. The CRA says to include all your income, and its underground-economy page lists contractors paid in cash among those who must report (CRA: business income; CRA: underground economy).

Build the estimate from whatever exists:

  • Cash register tapes, receipt books and daily till counts.
  • Booking calendars or job lists multiplied by the price actually charged.
  • Supplier purchases and the usual selling price of what was bought.
  • The owner's account of typical weeks, with the months it covers.

The CRA pages cited here set no estimating formula. Write down the method, the inputs and who supplied them, and mark each figure as an estimate. Record the cash at its full amount and any expense paid out of it separately, rather than netting the two.

Cash the owner kept needs its own record. For a sole proprietor it is a draw. For a corporation, classify each amount from its supporting facts as pay, a dividend or a loan. A withdrawal with no support can be a taxable shareholder benefit (Income Tax Act, section 15), and a loan entry alone does not make a debt; see corporate income in a personal account and shareholder loans.

How do I rebuild expenses when there are no receipts?

A statement line gives the payee, date and amount; the supplier supplies the rest. Ask each supplier for a duplicate invoice or an account history first. When a seller gives no receipt, the CRA says to write the seller's name and address, the amount, the date and the transaction details in your expense journal (CRA: business records).

A statement does not show what was bought or how much was for the business. Mixed-use costs such as a vehicle or home office need a business-use basis; for a vehicle, see rebuilding a vehicle logbook. Owner draws, transfers to yourself, personal purchases and loan principal are not business expenses. Nor is a payment to a credit card: the purchases are on the card statement, so include the card account in the set and count each purchase once. Equipment and other long-lasting property is generally claimed over several years as capital cost allowance, not all in the year it is bought (CRA: capital cost allowance). For what the CRA accepts without a receipt, see claiming expenses with no receipts.

GST/HST has a stricter test. An input tax credit, the GST/HST paid on business purchases that is taken off the tax you owe, needs sufficient documentary evidence in hand before it is claimed (CRA: input tax credits), so tax cannot be inferred from a card charge. Most registrants must also claim within four years, so credits for the oldest periods may be out of time (Excise Tax Act, section 225). On a T2125, show each expense net of the input tax credit claimed on it, so the same tax is not deducted twice (CRA: T2125 expenses).

Am I registered for GST/HST, and how do I estimate the tax inside my deposits?

A registered business has a GST/HST account number alongside its business number (CRA: register for a GST/HST account). Look for it on CRA letters, filed returns or the business's CRA account rather than going by memory. With none, test your sales: a business must register once its taxable sales, zero-rated sales included, pass $30,000 in one calendar quarter or across four consecutive calendar quarters (CRA: when to register). Count each sale in the quarter it became due, or was paid if earlier. The count is worldwide and includes associates' sales; it leaves out financial services, capital property and goodwill (Excise Tax Act, section 148). Taxi operators and commercial ride-sharing drivers must register from their first taxable fare, whatever their sales (CRA: register). The effective date is in when to register for GST/HST.

Your positionWhat the deposits holdWhat to do
Never registered, no taxi or ride-sharing, and taxable sales (zero-rated included, associates' counted) never passed the limitNo GST/HST, unless customers were charged someIf no invoice showed tax or added it to the price, the deposit is the sale; do not back tax out. Tax you did collect is held in trust for the Crown (Excise Tax Act, section 222); see tax-included prices and GST/HST. Keep the quarterly totals that show you stayed under.
RegisteredTax, where customers paid itBack the tax out of taxable deposits, then file a return for each reporting period.
Passed the limit but never registeredPossibly taxTax applies to taxable sales from the date you stopped being a small supplier (CRA: when to register), charged or not (RC4022). Find that date first.
Sales that are exempt or zero-ratedNo taxKeep the proof of why. See exempt, zero-rated and out-of-scope sales.

For a registered business, or a period when registration was required:

  1. Total taxable sales by calendar quarter, each counted when it became due or was paid if earlier, to find the date you stopped being a small supplier.
  2. Set aside sales that carry no tax.
  3. For taxable deposits where tax was shown on the invoice or added to the price, take the tax out with the tax fraction for the rate: the rate divided by one plus the rate. The CRA lists the fractions in RC4022, and its reverse calculator splits a tax-included total. Use the fraction only on a total of price plus GST/HST. If PST is also in the deposit, separate it first, because GST is worked out on the price without the PST (CRA: which rate).
  4. Count each invoice's tax once, in the period when payment was received or came due, whichever was first. A registrant is liable on that earlier day, and the CRA usually treats payment as due on the invoice date (RC4022; Excise Tax Act, section 225). Add the tax on invoices that came due in the period but are unpaid, and take out of step 3 any deposit that pays an invoice already counted in an earlier period. Keep one invoice list across all periods.
  5. If tax was never mentioned to the customer, how the price splits is a separate question; see tax-included prices and GST/HST.

A registrant required to charge GST/HST who did not is still liable and includes the tax in the return for the period it should have been charged (RC4022); see registered but did not charge GST/HST. Missing returns, due dates and estimated assessments are covered in unfiled GST/HST returns and estimated assessments.

Which rate applies in my province, and what changes in Quebec or where PST applies?

The rate follows where the sale is made, not where the business sits (CRA: place of supply). For delivered goods that is the delivery province. For services, the CRA's general rules start from the Canadian address the supplier has obtained for the customer. With customers in more than one province, see charging GST/HST, PST and QST by province.

Where the sale is madeGST or HSTSeparate provincial tax
Alberta, Northwest Territories, Nunavut, Yukon5% GSTNone
British Columbia5% GSTPST 7%

Quebec5% GSTQST 9.975%
Ontario13% HSTNone
Nova Scotia14% HSTNone
New Brunswick15% HSTNone
Newfoundland and Labrador15% HSTNone
Prince Edward Island15% HSTNone

These are today's rates from the CRA's rate table, which also lists earlier date ranges. Use the rate in force when each sale was made, subject to the CRA's transition rules. Nova Scotia's HST rate was 15% from April 1, 2013 to March 31, 2025.

British Columbia, Saskatchewan and Manitoba run their own sales taxes, which apply to certain goods and services only and are administered by the province, outside the GST/HST return (British Columbia; Saskatchewan; Manitoba). See provincial sales tax.

Quebec changes the filing, not only the rate. In Quebec, Revenu Québec generally administers the GST/HST (RC4022), a corporation located in Quebec or Alberta files a separate provincial corporate return (CRA: T2), and Quebec residents may need a separate provincial return (CRA: Quebec package). This page covers CRA-administered tax only.

Which forms do I file for each year: T2125 for a sole proprietor, T2 for a corporation?

Each tax year needs the return of whoever earned the income: a T2125 with the owner's T1 for a sole proprietor, a T2 for a corporation. Income a corporation earned is reported on its T2, not on its owner's T2125.

Who earned the incomeFiled for each yearNotes
Sole proprietorT1 with Form T2125Tax is due April 30; a self-employed filer's return is generally due June 15. The CRA lists the T2125 for earlier years.
PartnershipNo income tax return of its ownEach partner reports a share on their own return. Some partnerships also file a T5013, for example when a partner is a corporation or a trust. For GST/HST, each partner other than a limited partner is jointly liable for the partnership's tax (Excise Tax Act, section 272.1).
CorporationT2 with its financial statement informationReturn due six months after each year-end; most balances are due 2 months after it, or 3 months for an eligible Canadian-controlled private corporation.
Any GST/HST registrantA GST/HST return for each reporting periodSeparate from the income tax return.

A sole proprietor has no legal status apart from the business and reports on a T1 with Form T2125 (CRA: sole proprietorship; Form T2125). A partnership does not pay income tax or file an income tax return itself (CRA: partnership). A corporation is a separate legal entity with its own T2 (CRA: corporation), and corporations, insurance corporations aside, should prepare their financial statement information with GIFI codes, the CRA's standard list for financial statement lines, and file it with the T2 (CRA: GIFI). So a corporation's rebuild covers more than sales: year-end bank balances from the statements, what the owner put in or took out, GST/HST owing, equipment bought and what is owed to and by the business.

When a sole proprietorship and a corporation share accounts, each deposit belongs to one of them. Which one depends on the facts, usually whose contract and invoice it was. Corporate income deposited personally is still corporate income; see corporate income in a personal account.

What can the CRA require or do if my records are inadequate?

The CRA can order specified records going forward and test income by indirect methods such as bank deposit analysis. Both the Income Tax Act and the Excise Tax Act let the CRA require a person who failed to keep adequate records to keep the records it specifies (Income Tax Act, section 230; Excise Tax Act, section 286).

If auditors cannot determine income or net tax from incomplete records, the CRA says they use other methods (CRA: records to keep). Its audit manual names inadequate or unreliable books as a reason for indirect verification, and bank deposit analysis is part of that testing (CRA audit manual). Records prone to error and business and personal accounts used interchangeably are among the triggers, and an audit can ask for the owner's personal bank statements (CRA: business audits). Labelling deposits yourself first means you can answer when the CRA asks what each one was.

A business must make its records and supporting documents available to the CRA when it asks (CRA: your responsibilities). For a missing deposit slip, the CRA's audit manual has auditors request a bank authorization to get a copy from the bank (CRA audit manual). A false statement or omission in a return, made knowingly or through gross negligence, carries a penalty of 50% of the understated tax and certain related amounts, never less than $100 (Income Tax Act, section 163).

When should a rebuild go to a professional before anything is filed?

Professional help is worth considering before anything is filed when any of these applies. They decide which entity reports each deposit, which year is filed first and how GST/HST is estimated, and a wrong call carries into every later year.

  • More than one year is unfiled, or a CRA letter, demand or estimated assessment has arrived.
  • A corporation is involved, or a sole proprietorship and a corporation share accounts.
  • Cash that never reached a bank is a large share of sales, or no record of it exists.
  • Taxable sales passed $30,000 and the business never registered, or it registered and did not charge tax.
  • Deposits will not reconcile, or accounts are missing.
  • Quebec, or more than one province, is involved.
  • Income arrives in a foreign currency or an account outside Canada, or a corporation's owner lives abroad.
  • A return already filed left out income.

Some exposure is personal. A corporation's directors can be liable for GST/HST it did not remit, with interest and penalties, unless they took the care a reasonably prudent person would; the CRA must assess within two years after someone last ceased to be a director (Excise Tax Act, section 323). The Voluntary Disclosures Program can cover a return at least one year late, but only if the application comes before an audit or investigation begins (CRA: VDP eligibility); see unfiled personal returns.

The work grows with the number of years, accounts, the share of cash and the number of entities. Gather the statements first, then talk the entity, year order and GST/HST questions through with bookkeeping help.

Example

Illustrative amounts in Canadian dollars.

Alberta hairstylist, first year in business

She deposited C$55,000. C$8,000 was personal transfers, leaving C$47,000: C$44,000 of fees and C$3,000 of tips. Tips are income, so they stay in her gross income, tracked apart from her fees.

Her fees by calendar quarter, counted when due, were C$10,000, C$11,000, C$12,000 and C$11,000. This counts fees only toward the GST/HST limit; whether tips count depends on the facts. After the third quarter her fees so far total C$33,000, over the limit. She stops being a small supplier at the end of October, the month after that quarter, and must charge GST from her first supply after that. Alberta has GST only. If her fees for November and December were C$7,500 and clients paid prices that already included tax, the GST inside is C$7,500 × 5/105 = about C$357. Fees through October carry no GST.

Ontario corporation, cash business

Three years of deposits total C$300,000, with no record of cash sales.

YearDepositsNot salesCash estimateGross receipts
1C$80,000C$5,000C$15,000C$90,000
2C$100,000C$0C$18,000C$118,000
3C$120,000C$10,000C$20,000C$130,000

"Not sales" is an owner loan in year 1 and a transfer from the owner's other account in year 3. The cash estimate comes from the owner and the booking records, with the method written down. If customers paid prices that included 13% HST, year 1 holds C$90,000 × 13/113 = about C$10,354 of tax, and sales before tax are about C$79,646. At C$90,000 of taxable sales the corporation is past the small-supplier limit, so HST was owed from the date it passed, whether or not customers were charged; if prices never mentioned tax, see tax-included prices and GST/HST. The corporation files one T2 for each of the three years. It traces the C$53,000 of cash into business spending, cash on hand and owner withdrawals, then classifies each withdrawal from its supporting facts.

Sole proprietor in British Columbia

She received C$40,000 of e-transfers in each of two years. She matches each by sender, message and invoice. In year 1, C$6,000 was family money, leaving C$34,000 of business receipts. In year 2, C$4,000 was family money, leaving C$36,000. She files one T2125 per year, each on that year's form. If her receipts are taxable sales, each year's total is above the small-supplier limit, so she checks whether GST registration was required and whether BC PST applies to what she sells.
