Moving from Calgary to San Antonio: Energy, Military, and the Smallest Rate Drop in Texas
Calgary to San Antonio isn’t the corridor with the biggest tax win, and it’s worth saying that up front instead of burying it. Alberta already charges the lowest provincial rate in the country, so trading it for Texas’s zero produces the smallest combined-rate drop of any Calgary-to-Texas move. What makes the corridor interesting isn’t the rate delta, it’s who’s actually making the move: reservoir engineers and energy analysts landing at Valero’s refining headquarters, finance and insurance people drawn to USAA, and a steady flow tied to Joint Base San Antonio, one of the largest military footprints in the country. The tax mechanics are still worth getting right, especially since two of the big line items, property tax and sales tax, move in the opposite direction from what most people expect on a move to Texas.
Alberta’s combined federal-plus-provincial top rate runs close to 48%, and Texas charges no income tax at all, state or city. That’s still a real drop, but it’s the smallest one in the whole Calgary-to-Texas set, because Alberta’s flat 15% top provincial bracket is already the lightest in Canada. Sales tax runs the other way: San Antonio combines a 6.25% state rate with a 2% city rate for 8.25% total, against Alberta’s GST-only 5%. Bexar County property tax, roughly 1.8% to 2.4% effective, also runs well above Calgary’s 0.6% to 0.8%.
Why is this the smallest tax drop in the Texas set?
Because Alberta was never the province with room to fall the furthest. Ontario and BC movers see their combined top rate drop from the low-to-mid 50s down to Texas’s federal-only 37%, a spread of 15 to 17 points. Alberta’s flat-bracket system tops out at 15% provincially above roughly $355,845 of taxable income, producing a combined top rate near 48%, so the same move to Texas closes a smaller gap. The drop is still real money at high income levels, just not the headline number other provinces get to claim.
What happens on the Alberta side when I leave?
You still trigger the standard departure tax: a deemed disposition of worldwide property, with the usual carve-outs for Canadian real estate and registered accounts, reported on the final T1 for the period ending on your departure date. Alberta’s version of this is genuinely the lightest in Canada to compute. There’s no surtax stacked on top of basic tax the way Ontario runs it, and the bracket structure is flat enough that a departure-year estimate is more predictable than almost anywhere else in the country.
Does San Antonio charge its own income tax?
No. Texas bars cities from levying their own income tax, full stop, so San Antonio funds itself through property tax, sales tax, and franchise fees instead. The one business-side item to know is the Texas franchise tax, a margin tax on gross receipts above roughly $2.47 million, which won’t touch a W-2 employee but matters if the move comes with a consulting practice or a new US entity attached.
Why are Calgary energy workers landing in San Antonio?
Three employers do most of the pulling. Valero Energy, the world’s largest independent petroleum refiner, runs its headquarters here and is a direct match for anyone coming out of Calgary’s oil and gas sector, refining, trading, and downstream operations roles all included. USAA’s headquarters adds close to 35,000 jobs in finance, insurance, and technology, a natural landing spot for Calgary’s energy-finance crossover. Layered on top of both is Joint Base San Antonio, combining Lackland, Fort Sam Houston, and Randolph into roughly 80,000 military and civilian positions, plus a defence-contractor ecosystem that includes SAIC and Booz Allen Hamilton. Rackspace Technology, H-E-B, Southwest Research Institute, and a growing Toyota manufacturing footprint round out the list.
What happens to RRSP and TFSA on this corridor?
The RRSP carries over cleanly under the treaty, and Texas doesn’t add anything to that math the way a state with its own income tax would. There’s no state addback competing for the same foreign tax credit, so the treaty election covered in the RRSP and TFSA guide does the same work here as anywhere else, deferral preserved, withdrawals taxed as ordinary federal income with the 15% treaty withholding rate creditable against the US bill.
The TFSA doesn’t get the same treatment. It isn’t recognized under the treaty, so the IRS treats it as a foreign trust, Form 3520 and 3520-A filings and PFIC exposure on the underlying holdings included. Close it before your departure date rather than carrying it across the border.
What happens to AHCIP when I leave Alberta?
Alberta Health Care Insurance Plan coverage runs through the last day of the month following your departure month, roughly a three-month tail depending on where in the month you actually leave. Leave in early June and coverage can run into September, which still means lining up US coverage well before that window closes. The move itself qualifies as a Special Enrollment Period event on the federal marketplace, giving 60 days from the move date to enroll in an employer plan or through healthcare.gov directly. Details are in the provincial health insurance guide.
How do property and sales tax compare on this move?
Both go up, and property tax goes up by a lot. Calgary’s municipal rate runs roughly 0.6% to 0.8% of assessed value, while Bexar County effective rates land closer to 1.8% to 2.4%, so a $500,000 home carries somewhere around $9,000 to $12,000 a year in San Antonio against $3,000 to $4,000 on the same value in Calgary. Sales tax moves the same direction: Alberta’s 5% GST with no provincial layer against San Antonio’s combined 8.25%, the 6.25% state rate plus the full 2% local add-on. Neither city charges a land transfer tax, so the one-time closing cost stays clean even as the carrying cost diverges hard.
| Calgary (Alberta) | San Antonio (Texas) | |
|---|---|---|
| Provincial/state income tax | 10% to 15% flat-bracket | None |
| City income tax | None | None |
| Combined top marginal rate | About 48% (federal plus Alberta) | About 37% (federal only) |
| Property tax | Roughly 0.6% to 0.8% of assessed value | Bexar County roughly 1.8% to 2.4% |
| Sales tax | 5% GST only | 8.25% combined state and local |
| Land transfer tax | None | None |
| Exit tax on departure | 15% flat provincial share, no surtax | N/A, no state exit tax |
Where do Calgary movers settle in San Antonio?
It splits by employer more than by lifestyle preference. Valero and USAA hires tend to land in the Stone Oak, Alamo Heights, or Dominion areas, closer to the north-side corporate campuses and with stronger school districts. Military-affiliated movers and JBSA-adjacent civilian contractors cluster closer to Lackland and Randolph, in neighborhoods on the west and northeast sides built around base access. Cost of living stays meaningfully below Austin or Dallas throughout, which is part of why the property tax hit still nets out favorably at most income levels.
What should I do before the move?
Get the departure-year deemed disposition estimate run against Alberta’s actual bracket structure early. It’s the most predictable exit calculation of any province, so there’s little excuse for surprises here. Close the TFSA before the departure date, confirm the RRSP treaty election is filed correctly on the first US return, and line up health coverage before the AHCIP tail runs out. Budget for the property and sales tax increase specifically, since assuming Texas is cheaper across the board is the single most common miscalculation on this corridor.
