Do the estimate on the IRS website.


The penalty is tiny though. We used to owe huge amounts 20-50k and the penalty was a joke. Now our employer lets us pick how much extra to withhold over the supplemental rate so we do that.

You should either elect for extra withholding, remove and exemptions, or worst case you could do estimated taxes to avoid the small penalty.

The supplemental rate jumps up to 37% once you make more than 1M for the year too, which limits the amount of error for W2 employees making variable income and large bonuses.

I upped my 401k withdrawal by a bit and that helped me owe a bit less. But you also might just need to adjust your withholdings all year long to account for this. There should be a calculator on the IRS site.

Same. The new SALT saved our butts this year. Went from $50K owed down to $20K due to SALT. Mostly due to 1099 income that we didn’t prepay taxes on and RSUs being under-withheld.

We have to pay estimated taxes quarterly because we have a lot of investment income.

I have this problem due to a lot of RSU compensation and vesting. I have just learned to set aside the extra cash.

We owed $11k last year because dh retired from the military and didn’t properly set up his withholding on his retirement pay. We also have investments that generate income that create tax liability. I just increased the withholding on my own pay and I think we’ll be okay this year.

You can ask your hr people if you can increase withholding on bonuses. Theoretically that should be easy enough for them to do.

We also have this problem. I just keep increasing our additional withholding. I’ve also changed what assets I hold in my brokerage account so they don’t spin off as much interest.

Doing the taxes this weekend and it's looking like we're going to owe an additional $8k. We've been having this problem each year and it keeps getting worse. I already have an extra $1500 per paycheck withheld, but it's still not enough. I think it's because an increasing amount of our income is coming from bonuses that are withheld at 22% and investment income that doesn't have any withholding, while our marginal rate is 35%. Is there a way to get your employer to withhold bonuses at a higher rate? Or is the only thing to do to increase our regular withholding even more?
