Here is the deal, until you've made it through your first quarterly tax check with Collective we can't tell you how much to set aside for tax payments. Likewise, if there is tax deadline before your first quarterly tax check, we can't tell you what to pay or file. Either follow previous guidance you may have received or skip the deadline and we will address it with you during your first quarterly tax check.
An extremely general rule of thumb to follow that will most likely (but not always) have you saving more than enough is to save 30% of your income. Once you are through your first quarterly tax check you can ask our tax accountants a more specific amount to save that is tailored to your unique situation.
