End-of-Year Tax Tips
Taxes: There's no getting around them. There are, however, tax-planning strategies that can help minimize your tax burden as we close out 2023. Here are three year-end tax moves to consider.
Maximize Your Retirement Contributions
Contributing pre-tax dollars is one way to lower your tax bill while growing your net worth. The amount you can contribute and the deadlines to make your contribution depend on the type of account you have.
- 401(k). If you have a 401(k) plan at work, you can contribute up to $22,500 in 2023 ($30,000 if you're 50 or older).1 You have until December 31 to make your contribution and have it reduce your taxable income for 2023.
- Traditional IRA.You can contribute up to $6,500 to a traditional IRA ($7,500 if you're 50 or older).2 The deadline to contribute to an IRA is your tax return filing deadline, not including extensions. That means you have until April 15, 2024*, to make contributions for the 2023 tax year.
Self-employed people have several options (in addition to a traditional IRA) when it comes to saving for retirement in a tax-advantaged account. Here are some other ways self-employed people may be able to save for retirement while reducing their tax bill.
- SEP IRA. Self-employed individuals can contribute up to 25% of net earnings, up to $66,000, for 2023.3 You have until the due date of your return (including extensions) to make your contribution. That gives you until October 15, 2024, to contribute for 2023, assuming you filed for an extension on your tax return.
- SIMPLE IRA. If you're self-employed and have 100 or fewer employees, you can contribute up to $15,500 to your own SIMPLE IRA ($19,000 if age 50 or older).4 The deadline to contribute is within 30 days of the end of the tax year.
- Individual 401(k). If you're a self-employed business owner with no full-time employees, you can contribute a maximum of $66,000 to a solo 401(k) in 2023 ($73,500 if you're 50 or older).5 That maximum contribution consists of up to 100% of your compensation from the company (capped at $22,500 in 2023) as your "employee" contribution, plus up to 25% of gross compensation for the "employer" contribution. The deadline to contribute is the filing deadline of your business tax return, not including extensions.
One way to maximize the tax benefits of giving is to bunch two or more years of charitable contributions into one year.
Bunch Your Charitable Giving
To get a tax break for your charitable giving, your total itemized deductions — including mortgage interest, state and local taxes, and charitable contributions — must be greater than the standard deduction available for your filing status.
For 2023, the standard deductions are $13,850 for single taxpayers and $27,700 for joint filers.6 When you couple this higher standard deduction with the $10,000 cap on state and local taxes, many taxpayers who historically itemized deductions now find it advantageous to claim the standard deduction instead.
One way to maximize the tax benefits of giving is to bunch two or more years of charitable contributions into one year. For example, if you usually donate $7,000 per year to your local food bank, you could donate $21,000 one year, itemize deductions that year and take the standard deduction for the next two years.
Donations must be made by midnight on December 31 in your time zone to deduct on this year's tax return. If mailing your donation, your envelope must be postmarked on or before December 317 for your donation to be deductible in the current year.
Make a Qualified Charitable Distribution
Individuals age 72 or older must take annual withdrawals from their tax-advantaged retirement accounts. These withdrawals are known as required minimum distributions (RMD). If you don't need the money to cover living expenses, consider giving it directly to charity — a tax strategy known as a qualified charitable distribution (QCD).
QCDs allow you to exclude your RMD from your taxable income, which can lower your tax burden. They can even potentially lower your Medicare Part B and D premiums, which are calculated based on your income from the prior year.8
The annual QCD limit is $100,000 per account owner,9 and donations must go directly from your IRA to the charity to qualify.

Trump vs. the Fed: Reshaping the Federal Reserve
The Family Office at Synovus Chief Investment Officer Mike Sluder discusses the Fed, influences of the Trump administration and areas of risk and opportunity for investment portfolios. President Trump has made it clear that he wants lower interest rates and believes that the current Fed has been unwilling to move quickly enough. Trump currently has three appointed members of the 12-member voting committee and will be able to appoint a new chair in 2026, along with an additional member in 2027. It is likely that the new composition of the Fed will be more willing to lower rates, even at the expense of higher inflation.
