Better idea:
Everyone go to *zero* withholding and pay your tax bill in cash.
That is against US tax law.
Taxes are actually owed on a quarterly basis in the US, as any business owner would know.
Employers are required to withhold from every paycheck.
Technically, if you have a big capital gain in one quarter, you should make a tax payment by the filing date for that quarter.
If you don’t do this in a single year, the IRS will let it slide. If it happens two years in a row, you could be subject to penalties.
Is this right? Hell no, but it’s been the law for many years.
If you do zero withholding then you have to pay estimated taxes quarterly and you must have paid in no less than 90% of what you owe at the end of the year.
