Unlike traditional 401(k) contributions, Roth amounts are not excluded from taxable wages.<\/li>\n<\/ul>\n\n\n\n<p><strong>Box 12: Elective Deferrals<\/strong><\/p>\n\n\n\n<p>Box 12 is where you use specific codes to identify non-taxable (at the time of contribution) deferrals.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Code D:<\/strong> This is commonly used to report elective deferrals to a <strong>section 401(k) plan<\/strong>.<\/li>\n\n\n\n<li><strong>What to Include:<\/strong> This section records the portion of the salary the employee did not receive immediately because it was deferred. This includes the standard deferral, any &#8220;catch-up&#8221; amounts for employees age 50 or older, and Roth contributions.<\/li>\n\n\n\n<li><strong>Consolidated Reporting:<\/strong> For employees 50+, standard elective deferrals and catch-up contributions are reported as a single sum in Box 12 using the appropriate code.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Understanding Contribution Limits<\/strong><\/p>\n\n\n\n<p>As an employer, it is vital to advise employees of their maximum annual contribution limits. For 2026, the overall limit on annual additions (including elective deferrals and employer matching) is generally the lesser of:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>100%<\/strong> of the participant&#8217;s compensation.<\/li>\n\n\n\n<li><strong>$72,000<\/strong> (or up to <strong>$83,250<\/strong> for those age 60 to 63), subject to cost-of-living adjustments.<\/li>\n<\/ol>\n\n\n\n<p><strong>Maximum Warning:<\/strong> Employers face a deduction limit for their contributions to defined contribution plans. This deduction cannot exceed <strong>25%<\/strong> of the compensation paid or accrued during the year to eligible employees.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Accounting for 401(k) Contributions<\/strong><\/p>\n\n\n\n<p>To keep your company&#8217;s books accurate throughout the year, follow this simplified recording process:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>Action<\/strong><\/th><th><strong>Recording in Company Books<\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Employee Elects Contribution<\/strong><\/td><td>Record the election in the HR account with the employee&#8217;s signature.<\/td><\/tr><tr><td><strong>Employer Pays Employee<\/strong><\/td><td>Record the <strong>entire gross amount<\/strong> (including plan contributions) as a <strong>Payroll Expense<\/strong>.&nbsp;<\/td><\/tr><tr><td><strong>Recording the Payment to the Employee<\/strong><\/td><td>Debit the Payroll Expense for the full amount (including the deferred amount); credit Cash and the 401(k) Liability accounts.<\/td><\/tr><tr><td><strong>Paying the 401(k) Plan<\/strong><br>(Employee Contributions)<\/td><td>When the company pays the plan, record the transaction by crediting Cash and debiting the  401(k) Liability account. <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Example Scenario (Tax Year 2026)<\/strong><\/p>\n\n\n\n<p>Consider an employee in Florida who earned <strong>$19,000<\/strong> in gross payroll.
