What Cross-Border Bookkeeping Costs for a Canadian With US Income: Two Currencies, Two Sets of Books, and the Reconciliation Between Them

Cross-border bookkeeping is ordinary bookkeeping with a second currency, a second chart of accounts mapping, and a second set of tax rules to book toward — and each of those multiplies hours. What makes it different: two functional currencies (the Canadian business earning USD from US clients converts every transaction for the Canadian books, with the exchange gains and losses on receivables, payables, and cash balances computed and booked — the FX layer that single-currency businesses never see); two tax systems' requirements (the Canadian books need the foreign tax credit inputs — US tax paid by category, US-source income by type; the US filings need US-basis fixed assets and US depreciation schedules that differ from Canadian CCA; and where a US entity exists, its own books in USD for its own return); two sets of information returns (the T1135 for the Canadian side's foreign property, the FBAR and 8938 where a US person is involved, the T1134 for a US corporation or LLC held by a Canadian — the entity guides); and the reconciliation between the two (the same income and expenses tied out in both currencies so that the foreign tax credit on each return is computed on figures that agree). The pricing model: the standard bookkeeping drivers (transaction volume, accounts, standard of close — the bookkeeping-cost guide) plus the cross-border multipliers — the number of currencies (two, with the FX computations), the number of entities (a Canadian corporation plus a US LLC is two sets of books plus an intercompany reconciliation), the number of tax filings the books must feed (T1 or T2, 1040-NR or 1120, state returns, the information returns), the sales-tax overlay (GST/HST on the Canadian side, US state sales tax where nexus exists — the GST guide), and the payroll overlay (Canadian payroll, US payroll for US employees, or the employer-of-record arrangement the remote-employee guide describes). The tiers, as the market prices them: a Canadian sole proprietor or single-owner corporation with US clients and no US entity — one set of books in CAD with USD transactions converted, FX booked, the foreign tax credit inputs tracked, GST/HST handled (zero-rated exports), modest transaction volume — priced above the standard single-currency tier by the FX and credit-input work, in the middle hundreds to about a thousand per month; a Canadian with a US rental or two — the Canadian books plus a USD property ledger with US depreciation, the net-election inputs for the 1040-NR, the T1135 and the T776 in CAD — priced similarly, scaling with the property count; a Canadian corporation with a US subsidiary or LLC — two sets of books (CAD and USD), intercompany transactions reconciled, transfer pricing documentation supported, the US entity's own return fed, the T1134 inputs maintained, and both countries' sales tax — priced in the low-to-mid four figures monthly, the tier most cross-border business owners are actually in once they have a US entity; a multi-entity operation with employees in both countries — the full tier with two payrolls, two sales-tax regimes, consolidated reporting, and a reviewed close — mid four figures and up. What the fee buys that a single-country bookkeeper's doesn't: correctly booked FX (the gains and losses that Canadian tax treats as income or capital depending on the transaction, and that a bookkeeper unfamiliar with them either omits or books wrong); tax-credit-ready ledgers (US tax paid tracked by type and year, so the T2209 is a lookup rather than a reconstruction); US-basis fixed asset schedules maintained alongside Canadian CCA; information-return inputs (T1135 cost amounts, FBAR maximum values, T1134 surplus accounts) produced from the books rather than reconstructed at year-end; and the reconciliation memo that shows both countries' preparers the same numbers. What drives the fee up: a US LLC (Canada sees a corporation — the mismatch that adds T1134 and FAPI work to the books, the entity guides' recurring warning); multiple US states (each a sales-tax and income-tax filing the books must support); US employees (US payroll or an employer of record); inventory crossing the border (customs, duties, two sales-tax regimes on the same goods); and — the largest driver — books that were kept single-currency for years and need the FX and US-basis layers rebuilt (the cross-border version of catch-up, priced as a project). How to keep it down: one accounting file with multi-currency enabled from the start (rebuilding it later is the expensive version); a chart of accounts designed for both returns (US tax paid, US-source income, and FX gain/loss as their own accounts); a decision about the US entity made with the tax analysis before the LLC is formed (the entity that Canada treats as a corporation is a permanent bookkeeping surcharge); US payroll through an employer of record rather than a US payroll registration where headcount is small; and the same firm preparing both countries' returns, so the reconciliation happens once. Fairlight's cross-border bookkeeping tiers are on the pricing page; the multipliers above are what any firm's cross-border quote is built from.

Key takeaways

• The multipliers: two currencies (FX gains and losses booked), two tax systems' requirements (credit inputs, US-basis assets vs CCA), two information-return sets (T1135, FBAR/8938, T1134), and the reconciliation between them.
• Tiers: a Canadian with US clients and no US entity (middle hundreds to about a thousand monthly); a Canadian with US rentals (similar, scaling with properties); a Canadian corporation with a US entity (low-to-mid four figures — two sets of books, intercompany, both sales-tax regimes); multi-entity with employees in both countries (mid four figures and up).
• What the fee buys: correctly characterized FX, credit-ready ledgers, parallel fixed-asset schedules, information-return inputs from the books, and one reconciliation both preparers use.
• The fee drivers: a US LLC (Canada's corporation treatment adds T1134 and FAPI work), multiple US states, US employees, cross-border inventory, and single-currency books that need the cross-border layers rebuilt.
• Keep it down: multi-currency from day one, a chart of accounts built for both returns, the entity decision made before formation, an employer of record for small US headcount, and one firm for both countries' returns.
• The rebuild is the catch-up of cross-border bookkeeping: years of single-currency books re-layered with FX and US basis is a project priced by the year.

Scoping cross-border bookkeeping

Entities (Canadian, US, both?) and their classifications in each country. Currencies and where FX arises (receivables, payables, cash balances). Tax filings the books must feed (T1/T2, 1040-NR/1120, states, T1135, FBAR/8938, T1134). Sales tax regimes (GST/HST, US states). Payroll (which country, how many). Transaction volume and accounts. Current books' condition (multi-currency? US basis tracked?). The answers place the engagement in a tier and reveal the rebuild, if any, before the monthly fee is quoted.

Worked example

Three Canadians with US income. One: a Montreal graphic designer billing US$120,000 a year to US clients from a Canadian sole proprietorship, no US entity, paid in USD to a USD account — one set of books with USD transactions converted, FX gains and losses on the USD balance booked, GST/HST zero-rated exports tracked, US tax paid (none — no US presence, the treaty's business-profits protection) nothing to credit but the income sourced for the T1; the fee sits above a single-currency designer's by the FX layer, in the middle hundreds monthly. Two: a Toronto couple with two Florida rentals held personally — the Canadian books plus a USD ledger per property with US depreciation for the 1040-NR net election, Canadian CCA computed separately for the T776, the T1135 at cost, and the credit inputs from the US returns; the fee scales with the two properties and sits near the top of the middle tier. Three: a Vancouver software company with a Delaware C corporation subsidiary, US$2 million of US revenue, six US employees on an employer of record, and sales-tax nexus in four states — two sets of books (CAD parent, USD subsidiary), monthly intercompany reconciliation supporting the transfer-pricing documentation, the subsidiary's Form 1120 and four state returns fed from its books, the parent's T2 with the T1134 surplus accounts maintained, GST/HST and four states' sales tax, and a reviewed close for the parent's lender; the fee is in the low-to-mid four figures monthly — and the company's decision, taken with the tax analysis before formation, to use a C corporation rather than an LLC is the reason the T1134 work is a maintenance item rather than a FAPI computation every year. Three businesses, one currency each at home, and a monthly fee that tracked the number of tax systems the books had to satisfy.

Practitioner note

Cross-border bookkeeping costs more because the books serve two tax systems, and the multipliers are structural — FX, parallel asset schedules, information-return inputs, and the reconciliation both preparers rely on. Our tiers are set by entities, currencies, and the filings the books must feed; our largest single fee driver is a US LLC Canada treats as a corporation, decided before formation or paid for annually; and our strongest recommendation is multi-currency from day one, because the rebuild of single-currency books is the cross-border version of catch-up.
