Last Minute Tax Planning Ideas In Light of the New Tax Bill

by | Dec 24, 2017 | Tax

High-income earners can bypass Roth IRA income limits using the backdoor Roth IRA strategy. This allows individuals to contribute to a non-deductible Traditional IRA and then convert those funds to a Roth IRA. This legal method has important tax considerations. 

Understanding the Tax Landscape 

The Pro-Rata Rule: A Key Factor 

It is important to understand the IRS’s pro-rata rule. If you have multiple Traditional IRAs with both pre-tax and after-tax contributions, the IRS requires that any conversion to a Roth IRA includes a proportionate share of both. This means you cannot select only the non-taxable funds for conversion. 

Example: With $10,000 in a Traditional IRA ($6,000 pre-tax and $4,000 non-deductible), converting $4,000 to a Roth IRA makes the taxable portion proportional to the pre-tax amount. (See IRS Publication 590-B for details.) 

Impact on Taxable Income 

The taxable portion of your conversion is added to your gross income for the year, which could potentially place you into a higher tax bracket. While this might increase your short-term tax costs, the long-term benefits of tax-free growth and withdrawals from a Roth IRA often outweigh the upfront cost. 

Tip: Before converting, calculate how the added income will affect your adjusted gross income (AGI) and marginal tax rate. (Refer to IRS Publication 590-A.) 

Filing Requirements: Ensure Proper Documentation 

Form 8606: Your Reporting Companion 

In order to remain compliant, it is necessary to file IRS Form 8606. This form reports non-deductible contributions and determines the taxable and non-taxable portions of your conversion. 

Form 8606 must be attached to your 2025 Form 1040, 1040-SR, or 1040-NR. You can submit Form 8606 independently if you are not required to file a tax return. 

Contribution and Income Limits 

For 2025, the total IRA contribution limit is $7,000 (or $8,000 for individuals aged 50 or older). Direct Roth IRA contributions are phased out at the following income levels: 

  • Married filing jointly: $230,000–$240,000 
  • Single: $146,000–$161,000 

Conversions from Traditional to Roth IRAs are permitted regardless of income level. However, it is important to note that taxes apply to pre-tax portion of the converted amount.  

Strategic Planning Guidelines 

Timing Your Conversion 

Consider converting early in the year to maximize tax-free growth. If you anticipate a lower-income year, that could also be an ideal time to convert and reduce your tax liability. 

Long-Term Advantages 

Despite the upfront tax impact, Roth IRAs offer significant long-term benefits, including tax-free retirement withdrawals and potential estate planning advantages. 

Avoiding Common Pitfalls 

Accurate reporting is critical. Errors on Form 8606 can lead to penalties or IRS scrutiny. Re-verify your calculations and documentation carefully.
