The Social Security Administration is urging Americans to watch their mailboxes for two essential tax forms that will start going out on December 26. These documents will play a critical role when filing federal income taxes, especially in light of new legislation that kicks in this year.
The forms, SSA-1099 and SSA-1042S, will detail how much of your Social Security benefits you received in 2025 may be subject to federal taxes. Online access to these forms will begin on December 25, with mailed copies starting December 26 and expected to arrive for most recipients by the end of January.
That timing matters because recent congressional changes affect how Social Security benefits are taxed. The 1099 forms report the total benefits received in 2025 to be reported to the IRS. These updates come amid measures passed earlier in 2025, including the One Big Beautiful Bill Act and the Social Security Fairness Act, both influencing tax liabilities for beneficiaries.
One notable change is a temporary $6,000 deduction for qualifying seniors intended to offset taxes on Social Security benefits. When combined with other tax provisions—such as an expanded standard deduction under the One Big Beautiful Bill Act and additional deductions of $2,000 for single filers or $3,200 for married couples filing jointly—many retirees could see a reduced tax bill. In fact, a single senior taxpayer could deduct up to $23,750 of their first-year income on their 2025 return, potentially eliminating federal taxes on that portion.
Experts emphasize that the largest benefits from these changes will go to middle- and lower-middle-income taxpayers. Still, the overall impact on any individual depends on how much other income they have and whether they receive lump-sum adjustments or changes to benefit amounts.
If you’re planning your retirement finances, consider strategies to supplement Social Security income. The Senior Citizens League recommends early saving and diversified retirement accounts, such as 401(k)s and IRAs.
- 401(k) plans: Employer-sponsored accounts with tax-deferred contributions and often employer matches. Prioritize maximizing contributions to capture matches.
- IRAs: Individual retirement accounts not tied to an employer, offering tax-deductible traditional-IRA contributions and tax-free growth until withdrawal.
- Additional planning: Depending on your overall income, you may see changes to taxable benefits or refunds as new laws take effect.
As always, it’s wise to review your withholdings. If these changes lead to higher Social Security benefits or new lump-sum payments, you may owe more in taxes than you did previously. A financial professional can help tailor your withholding and tax strategy to your circumstances.
