RRSP vs TFSA in New Brunswick: Which Account Wins at Your Income

New Brunswick sits in the middle of the pack for marginal tax rates, but that middle ground creates a clearer cutoff than most provinces for the RRSP versus TFSA decision.

At $40,000 in New Brunswick, your combined federal and provincial marginal rate is roughly 26.7%. At $60,000, it jumps to 32.7%. At $80,000, you're paying 37.4% on your next dollar. That progression matters because it determines how much tax the RRSP saves you now - and how much you'll pay when you withdraw it later.

Here's how the math works. Put $5,000 into an RRSP at $40k and you get back roughly $1,335 in tax refunds. At $60k, that same contribution gets you $1,635 back. At $80k, it's $1,870. The higher your current rate, the bigger the immediate tax break.

But the RRSP only wins if your tax rate today is higher than it will be in retirement. Most people assume it will be - they're planning to spend less, earn less, have fewer responsibilities. That assumption works for higher earners. It breaks down below $55,000.

Someone earning $40,000 in New Brunswick is already in a relatively low bracket. Their retirement income might not drop much. If they're still paying 26.7% when they withdraw, the RRSP gave them a tax deferral, not savings. Meanwhile, the TFSA grows tax-free and withdraws tax-free. No guessing required.

The break-even point in New Brunswick lands around $55,000. Above that income, the RRSP refund is large enough that even if your retirement tax rate stays the same, the refund invested properly makes up the difference. Below $55,000, the TFSA's tax-free growth usually wins.

There's one catch with New Brunswick specifically: the province has been aggressive about raising tax rates in recent years. If you're betting on lower taxes in retirement, you're betting against that trend. The TFSA hedges that risk completely.

The exception is if you're planning to retire in a different province. Alberta's top marginal rate is about 8 percentage points lower than New Brunswick's. If you're saving RRSP money in New Brunswick today and withdrawing it in Alberta later, the arbitrage works in your favour even at lower income levels.

For most New Brunswickers: RRSP above $55,000, TFSA below that. Max out the 2025 TFSA room first if you're anywhere close to that line.
