Lacerte Tax Idea Exchange
Submitted by michaelacpa on 08-28-2025 02:43 PMCA Form 3519 is an extension for individual taxpayers. The amount of the payment that Lacerte populates in this form does not include any ISR or underpayment penalties, so when you generate this extension and you want your client to be paid up for the year, you have to override the field in Screen 9. The software states that it "defaults to amount due". This is incorrect and misleading. The amount due includes ISR penalties and underpayment penalties, but the amount that defaults to Form 3519 is only the tax. This is very misleading to the client and practicioner because a payment is made on extension and then when the return is filed addtional amounts are due.
Please update the software to populate the actual amount due on Form 3519 or update the field name to say "defaults to amount of tax due, penalties are not included".
