Every year, the Internal Revenue Service announces cost-of-living adjustments that affect contribution limits for retirement plans, thresholds for deductions and credits, and standard deduction and personal exemption amounts. Here are a few of the key adjustments for 2018.
Employer retirement plans
- Employees who participate in 401(k), 403(b), and most 457 plans can defer up to $18,500 in compensation in 2018 (up from $18,000 in 2017); employees age 50 and older can defer up to an additional $6,000 in 2018 (the same as in 2017).
- Employees participating in a SIMPLE retirement plan can defer up to $12,500 in 2018 (the same as in 2017), and employees age 50 and older can defer up to an additional $3,000 in 2018 (the same as in 2017).
The limit on annual contributions to an IRA remains unchanged at $5,500 in 2018, with individuals age 50 and older able to contribute an additional $1,000. For individuals who are covered by a workplace retirement plan, the deduction for contributions to a traditional IRA is phased out for the following modified adjusted gross income (AGI) ranges:
The 2018 phaseout range is $189,000 – $199,000 (up from $186,000 – $196,000 in 2017) when the individual making the IRA contribution is not covered by a workplace retirement plan but is filing jointly with a spouse who is covered.
The modified AGI phaseout ranges for individuals to make contributions to a Roth IRA are:
Estate and gift tax
- The annual gift tax exclusion for 2018 is $15,000, up from $14,000 in 2017.
- The gift and estate tax basic exclusion amount for 2018 is $11,200,000, up from $5,490,000 in 2017.
There is no personal exemption amount for 2018; it was $4,050 in 2017. For 2018, there is no phase-out of personal exemptions or overall limit on itemized deductions once AGI exceeds certain thresholds.
For 2017, personal exemptions were phased out and itemized deductions were limited once AGI exceeded $261,500 (single), $287,650 (HOH), $313,800 (MFJ), or $156,900 (MFS).
These amounts have been adjusted as follows:
The additional standard deduction amount for the blind or aged (age 65 or older) in 2018 is $1,600 (up from $1,550 in 2017) for single/HOH or $1,300 (up from $1,250 in 2017) for all other filing statuses. Special rules apply if you can be claimed as a dependent by another taxpayer.
