How we think about Tecogen Inc/Waltham Ma at Evermore
Tecogen Inc/Waltham Ma (TGEN) operates in the Building sector and trades on OTC MARKETS. A single company — no matter how strong — carries concentration risk that a diversified portfolio does not. We generally frame any individual stock as one holding within a broader plan, sized so that a bad quarter for one company can't derail your goals.
How Tecogen Inc/Waltham Ma is taxed for Canadian investors
For a Canadian holding a US-listed stock like TGEN, two taxes matter. Capital gains on a sale are 50% taxable in Canada (see capital gains tax). Dividends paid by a US company face a 15% US withholding tax under the Canada–US tax treaty (with a valid W-8BEN on file). Prices here are quoted in USD, so currency movements between the USD and the Canadian dollar also affect your real return.
Can you hold Tecogen Inc/Waltham Ma in a TFSA or RRSP?
Yes — US-listed stocks are qualified investments for both. But the accounts are not equal for US dividends: inside an RRSP, US dividend withholding tax is waived under the treaty, while inside a TFSA the 15% withholding still applies and can't be recovered. For US dividend-payers, the RRSP is usually the more tax-efficient home.
