2024 Year-End Tax Planning

It’s that time of year again. The air is cool and the Election is in the rear-view mirror. That can only mean one thing when it comes to personal finance: time to start thinking about year-end tax planning.

I’ll provide some commentary about year-end tax planning to consider, with headings corresponding to the timeframe required to execute. 

As always, none of this is advice for your particular situation but rather it is educational information. 

Urgent

By urgent, I mean those items that (i) need to happen before year-end and (ii) may not happen if taxpayers delay and try to accomplish them late in the year. 

Donor Advised Fund Contributions

The donor advised fund is a great way to contribute to charity and accelerate a tax deduction. My favorite way to use the donor advised fund is to contribute appreciated stock directly to the donor advised fund. This gets the donor three tax benefits: 1) a potential upfront itemized tax deduction, 2) removing the unrealized capital gain from future income tax, and 3) removing the income produced by the assets inside the donor advised fund from the donor’s tax return. 

In order to get the first benefit in 2024, the appreciated stock must be received by the donor advised fund prior to January 1, 2025. This deadline is no different than the normal charitable contribution deadline.

However, due to much year end interest in donor advised fund contributions and processing time, different financial institutions will have different deadlines on when transfers must be initiated in order to count for 2024. Donor advised fund planning should be attended to sooner rather than later. 

Taxable Roth Conversions

For a Roth conversion to count as being for 2024, it must be done before January 1, 2025. That means New Year’s Eve is the deadline. However, taxable Roth conversions should be done well before New Year’s Eve because 

  1. It requires analysis to determine if a taxable Roth conversion is advantageous, 
  2. If advantageous, the proper amount to convert must be estimated, and 
  3. The financial institution needs time to execute the Roth conversion so it counts as having occurred in 2024. 

Remember, generally speaking it is not good to have federal and/or state income taxes withheld when doing Roth conversions!

Gotta Happen Before 2026!!!

Before the Election, many commentators said “you’ve gotta get your Roth conversions done before tax rates go up in 2026!” If this were X (the artist formerly known as Twitter), the assertion would likely be accompanied by a hair-on-fire GIF. 😉

I have disagreed with the assertion. As I have stated before, there’s nothing more permanent than a temporary tax cut! Now with a second Trump presidency and a (likely) Republican Congress, it is likely that the higher standard deduction and rate cuts of the Tax Cuts and Jobs Act will be extended. 

Regardless of the particulars of 2025 tax changes, I recommend that you make your own personal taxable Roth conversion decisions based on your own personal situation and analysis of the landscape and not a fear of future tax hikes.

Adjust Withholding

This varies, but it is a good idea to look at how much tax you owed last year. If you are on pace to get 100% (110% if 2023 AGI is $150K or greater) or slightly more of that amount paid into Uncle Sam by the end of the year (take a look at your most recent pay stub), there’s likely no need for action. But what if you are likely to have much more or much less than 100%/110%? It may be that you want to reduce or increase your workplace withholdings for the rest of 2024. If you do, don’t forget to reassess your workplace withholdings for 2024 early in the year.

One great way to make up for underwithholding is through an IRA withdrawal mostly directed to the IRS and/or a state taxing agency. Just note that for those under age 59 ½, this tactic may require special planning.  

Backdoor Roth IRA Diligence

The deadline for the Backdoor Roth IRA for 2024 is not December 31st, as I will discuss below. But if you have already completed a Backdoor Roth IRA for 2023, the deadline to get to a zero balance in all traditional IRAs, SEP IRAs, and SIMPLE IRAs is December 31, 2024

Solo 401(k) Planning

There’s plenty of planning that needs to be done for solopreneurs in terms of retirement account contributions. 

The Solo 401(k) can get complicated. That’s why I wrote a book about them and post an annual update on Solo 401(k)s here on the blog. 

Year-End Deadline

These items can wait till close to year-end, though you don’t want to find yourself doing them on New Year’s Eve.

Tax Gain Harvesting

For those finding themselves in the 12% or lower federal marginal income tax bracket and with an asset in a taxable account with a built-in gain, tax gain harvesting prior to December 31, 2024 may be a good tax tactic to increase basis without incurring additional federal income tax. Remember, though, the gain itself increases one’s taxable income, making it harder to stay within the 12% or lower marginal income tax bracket. 

I’m also quite fond of tax gain harvesting that reallocates one’s portfolio in a tax efficient manner. 

Tax Loss Harvesting

The deadline for tax loss harvesting for 2024 is December 31, 2024. Just remember to navigate the wash sale rule

RMDs from Your Own Retirement Account

The deadline to take any required minimum distributions from one’s own retirement account is December 31, 2024. Remember, the rules can get a bit confusing. Generally, IRAs can be aggregated for RMD purposes, but 401(k)s cannot. 

RMDs from Inherited Accounts

The deadline to take any RMDs from inherited retirement accounts is December 31st. For some beneficiaries of retirement accounts inherited during 2020, 2021, 2022, and 2023, the IRS has waived 2024 RMDs. That said, all beneficiaries of inherited retirement accounts may want to consider affirmatively taking distributions (in addition to RMDs, if any) before the end of 2024 to put the income into a lower tax year, if 2024 happens to be a lower taxable income year vis-a-vis future tax years. 

Can Wait Till Next Year

Traditional IRA and Roth IRA Contribution Deadline

The deadline for funding either or both a traditional IRA and a Roth IRA for 2024 is April 15, 2025. 

Backdoor Roth IRA Deadline

There’s no law saying “the deadline for the Backdoor Roth IRA is DATE X.” However, the deadline to make a nondeductible traditional IRA contribution for the 2024 tax year is April 15, 2025. Those doing the Backdoor Roth IRA for 2024 and doing the Roth conversion step in 2025 may want to consider the unique tax filing when that happens (what I refer to as a “Split-Year Backdoor Roth IRA”). 

HSA Funding Deadline

The deadline to fund an HSA for 2024 is April 15, 2025. Those who have not maximized their HSA through payroll deductions during the year may want to look into establishing payroll withholding for their HSA so as to take advantage of the payroll tax break available when HSAs are funded through payroll. 

The deadline for those age 55 and older to fund a Baby HSA for 2024 is April 15, 2025. 

2025 Tax Planning at the End of 2024

HDHP and HSA Open Enrollment

It’s open enrollment season. Now is a great time to assess whether a high deductible health plan (a HDHP) is a good medical insurance plan for you. One of the benefits of the HDHP is the health savings account (an HSA).

For those who already have a HDHP, now is a good time to review payroll withholding into the HSA. Many HSA owners will want to max this out through payroll deductions so as to qualify to reduce both income taxes and payroll taxes.

Self-Employment Tax Planning

Year-end is a great time for solopreneurs, particularly newer solopreneurs, to assess their business structure and retirement plans. Perhaps 2024 is the year to open a Solo 401(k). Often this type of analysis benefits from professional consultations.
