This field will appear if this is your first time filing a 1701Q (Q2 onwards) in Taxumo. Otherwise, this field is not asked for by Taxumo - instead Taxumo will automatically get it from your previous filings.
To fill out this field, get your previous quarter's 1701Q and check the following section:
Get the SUM of Rows 57 and 58.
You enter this SUM in the "Tax Withheld for Previous Quarters" field.
If it's a negative number, enter it as a negative number.
If this is the first 1701Q you're required to file (i.e. you just registered), enter a ZERO in this field.
If you missed your previous 1701Q filings, you will have to add up all your Form 2307's that you've received for the taxable year up to the previous quarter. You also have the option of filing these late filings via Taxumo (inc penalties computed) - simply send us a note and we'll help you with the process.
