Yes, you'll have access to your data, Yevanis. I'll provide details about what will happen to your data after you cancel your QuickBooks Online (QBO) subscription.
QuickBooks holds onto your data for a year when you cancel your subscription. Thus, you can utilize data inside it for tax purposes at the end of the year. However, please be aware that you'll only have read-only access to those files and won't be able to modify them once canceled. Visit this article for more information: Cancel your QuickBooks Online subscription or trial.
Furthermore, here's an article to help you secure a copy of your data from QBO: Export data out of QuickBooks Online.
Our team can offer additional support if you have other questions about data inside QuickBooks or need assistance handling your subscription. Feel free to visit us anytime or leave a comment below so we can respond as soon as possible.
