If I bought the 8 standard returns, how can I use it for next year? do i need to download 2018 software or just use the 2017 software?
I'm not sure what you're asking.
If you're looking for our download software editions for tax year 2017 and you haven't purchased software for 2017 yet, you can find them here: https://turbotax.intuit.ca/personal-tax-software/download-tax-software.jsp
If you purchased a CD for tax year 2017 and decided you'd like to install from a download instead, you can. You'll need the Installation Key Code you got with your CD purchase to install: https://turbotax.community.intuit.ca/replies/3001486
If you'd like to try one of our online editions, there's nothing to download or install, because they run in your web browser. Check them out here: https://turbotax.intuit.ca/personal-tax-software/online-tax-software.jsp
Your purchase only covers the tax year in question. When it's time to prepare your tax return for tax year 2018, you'll need to purchase tax software for tax year 2018.
So that means the remaining 7 returns are useless now? I can't use them next year??
Yes, that's right. If you only need one or two returns this year, consider purchasing just the returns you need and then give us a call for a refund on your 8-return purchase.
