Most accountants raise tax issues six months after year-end when the window has already closed. Because we're inside your books daily, we flag the decisions that move your bill while there's still time to make them.

WHAT WE HANDLE

One team for thewhole tax picture.
One team for thewhole tax picture.
(CA & US)
Corporate tax return preparation & filing.
T2 for Canada, federal and state returns for the US, or both for cross-border entities. Prepared by senior staff, reviewed before filing.
CROSS-BORDER
Cross-border tax structuring.
Treaty positions, transfer pricing basics, permanent establishment risk, and parent/subsidiary structure for companies operating on both sides of the border.
Sales tax, GST/HST & US state nexus.
Nexus monitored as you hire and sell into new jurisdictions. Registrations, remittances, and filings handled before they become a liability.
(CA & US)
Equity & stock option planning.
Option grants, 83(b) elections, and the tax mechanics of an equity comp plan — structured before grants go out, not untangled after.
Year-round corporate tax strategy.
Capital purchase timing, owner compensation mix, dividend vs. salary, loss utilization, and entity structure — modeled while the decisions are still live.
SR&ED & US R&D tax credits.
We track qualifying activity throughout the year — not reconstructed at filing — so the claim is documented, defensible, and as large as it legitimately can be.
CRA & IRS audit defence.
If an authority comes knocking, we respond. Because the books were right all year and positions were documented, defence is a process — not a panic.
Pre-transaction tax planning.
Fundraise, acquisition, or sale on the horizon? We structure the tax position ahead of the event, when it still moves the outcome.

The more your business is worth and the more it crosses borders, raises capital, or invests in R&D, the more a missed tax decision costs. Proactive tax is the difference between keeping and forfeiting real money, every single year.

01
FOR FOUNDERS
SR&ED documented as you build, equity comp structured before grants, and a tax position that's diligence-ready when you raise.
02
FOR CROSS-BORDER COMPANIES
One team for both sides of the border. No coordinating a Canadian accountant with a US one who never speak to each other.
03
FOR ESTABLISHED OPERATORS
Owner-comp mix, capital timing, and loss utilization optimized every year, not left to a once-a-year filing.
04
FOR R&D-HEAVY BUSINESSES
Tech and agency R&D credits tracked in real time, so the claim is maximal and audit-ready by default.
