Will I be charged for applying for an Online Signature PIN for e-filing Form 941?

No, TaxBandits does not charge anything. You can apply for an Online Signature PIN here. A 10-digit signature PIN will be mailed to your address once the IRS accepts your PIN request. Send an acknowledgment receipt to the IRS within ten days from the day you receive it. You will have to activate it before using it for e-signing your Form 941 in TaxBandits. It will take about 45 days to finish the PIN registration process.
