briskmason37 said:Could someone please clarify something for me: is the income tax and local surtax that a sole proprietor pays based on their assessment from the IRS considered a business expense? Or should I be recording it in my books by entering the amount with a minus sign in front of it? Alternatively, do I skip the bookkeeping entirely and just include it as part of a breakdown of bank account activity when I file my tax return, essentially treating it as something that wasn't included in the business expenses?
Income tax isn't really a business expense, so you don't book it as one; rather, it's essentially a portion of your total earnings that gets diverted.
At the end of the fiscal year, you file your tax return, and on the penultimate page, you report your total income alongside the various estimated tax payments you made throughout the year—you can just keep your receipts to tally them up or check your digital payment history—which allows you to calculate your final liability for the year.
There's no need to attach extra documentation detailing your bank transactions, since the IRS already has access to your accounts and can see all your income tax and surtax payments on their own records.
