Last Chance for 2025 Tax Savings: Fund Employer Retirement Plans Before Extended Deadlines
August 27, 2026
Share:September and October are critical months for businesses looking to maximize tax savings through retirement plan contributions. Employer-sponsored plans like SEP IRAs, Solo 401(k)s, and profit-sharing plans offer substantial deductions, but only if contributions are made by your business’s tax filing deadline, including extensions.
Deductibility Deadline by Entity Type
To deduct employer contributions for a given tax year, they must be deposited by the due date of the business’s federal tax return, including any extensions.
| Entity Type | Standard Deadline | Extended Deadline |
| C-Corporation (or LLC taxed as C-Corp) | April 15 | October 15 |
| S-Corporation (or LLC taxed as S-Corp) | March 15 | September 15 |
| Partnership (or LLC taxed as Partnership) | March 15 | September 15 |
| Sole Proprietorship (or LLC taxed as Sole Prop) | April 15 | October 15 |
Can Plans Still Be Set Up for 2025?
Yes! Certain retirement plans can still be established in 2026 and funded for 2025 contributions.
Missed the Deadline?
If you missed the cutoff to fund a plan for 2025, now is the perfect time to start planning for 2026. Starting now ensures you won’t miss out on next year’s tax-saving opportunities.
