States with a Local Tax estimate should also be tagged with the income types that apply to them.

Social Security is also often not taxed by states.

Right, state taxes for California are significantly incorrect because the state does not tax Social Security income. In my case this makes a large difference in projection numbers and outcomes.

Another use case is that not all contributions to retirement savings are tax-deferred at the state level. For example, in New Jersey, contributions to 401(k) plans do reduce your state taxable income in that year, but contributions to 403(b) plans do NOT! See https://www.nj.gov/treasury/taxation/section403.shtml

Can we generalise this feature?

In the UK national insurance is not paid on pension income but there is no way to express this.

I’ve had to do the workaround of tax consequences at retirement for the period where I’ll be living only on pension.

However, I also have a period where I will be working and also receiving pension income pre-retirement and currently tax analytics is showing national insurance as being paid on that pension income

It would be great if it were possible to choose which income tax types are application on a per income basis

This would also be useful to expats. For instance, US/France treaty means my taxable brokerage account is taxed in the US at 10%, but my husband’s brokerage in France would be 30%

Agree on usefulness for expats. We often have very different tax rates than our spouses (USA global taxation issues…)

I would also like to specify Treasury investments in taxable accounts, so that state tax is not taken out against those.

More flexibility on taxes would be very welcome! Things that I cannot model in my case (Netherlands) - interest on savings is tax free. PL taxes is as income. - the tax brackets change at pension age. It is taxed separately, and when spouses are not the same age PL currently cannot accommodate for different brackets per person - wealth tax have peculiar cash flow result. But is became such a long story I’ll make a separate request 😊

Odds are that might be harder to do as you’ve stated it.

But if you split your actual taxable account into two cards in PL, one holding the “regular” stuff and one holding the treasuries, then you could apply tax-ability at that pseudo-account card level without Kyle having to create a way to do it within the card for a portion of the assets in that card.

In the meantime, you can roughly estimate that with a tax credit that is set to grow in a way that mimics your best guess at the growth of treasuries. I’ve had to do that with the tax credit for my military pension and state’s SS exemption.

“But in theory you could also specify an override on the Income item itself, if you’re using Custom Income for example.”

Being able to tag income with a specific state (tax) would be useful for situations where a user owes tax out-of-state on specific income while the balance of their plan is taxable elsewhere. E.g. For New York, nonresidents are taxable on NY-based source income in many circumstances even if not living there, such as remote work being done elsewhere for an employer based in NY state (https://www.tax.ny.gov/pit/file/nonresidents.htm)
