In 2018, the IRS introduced changes to how Social Security benefits are taxed. This guide provides a complete 2018 worksheet to help you calculate your taxable Social Security income accurately.
What is Taxable Social Security?
Social Security benefits are generally not taxable, but part of your benefits may be subject to federal income tax if your total income exceeds certain thresholds. The amount of your benefits that is taxable depends on your filing status and modified adjusted gross income (MAGI).
In 2018, the IRS introduced a new rule that requires you to report all your income on your tax return, including Social Security benefits, to determine if any portion is taxable.
2018 Taxable Social Security Worksheet
The 2018 taxable Social Security worksheet is a form provided by the IRS to help you calculate how much of your Social Security benefits are taxable. Here's how to use it:
- Determine your total income for the year, including Social Security benefits.
- Use the worksheet to calculate your taxable Social Security benefits based on your filing status and MAGI.
- Report the taxable portion on your tax return.
Formula: Taxable Social Security = Total Social Security Benefits - (Bracket Amount × 0.50)
Where Bracket Amount is the amount of your MAGI that exceeds the applicable threshold.
How to Calculate Taxable Social Security
To calculate your taxable Social Security benefits, follow these steps:
- Calculate your MAGI by adding all your income and subtracting certain deductions.
- Determine your filing status (single, married filing jointly, etc.).
- Use the 2018 taxable Social Security worksheet to find the applicable threshold for your filing status.
- Subtract the threshold from your MAGI to find the bracket amount.
- Multiply the bracket amount by 0.50 to find the taxable portion of your Social Security benefits.
- Subtract this amount from your total Social Security benefits to find your taxable Social Security income.
| Filing Status | Threshold |
|---|---|
| Single | $25,000 |
| Married Filing Jointly | $32,000 |
| Married Filing Separately | $0 |
| Head of Household | $38,000 |
Example Calculation
Let's say you're single, your total income is $30,000, and your total Social Security benefits are $1,200. Here's how to calculate your taxable Social Security:
- Your MAGI is $30,000.
- Your filing status is single, so the threshold is $25,000.
- The bracket amount is $30,000 - $25,000 = $5,000.
- Multiply the bracket amount by 0.50: $5,000 × 0.50 = $2,500.
- Subtract this from your total Social Security benefits: $1,200 - $2,500 = -$1,300.
In this case, your Social Security benefits are not taxable because the result is negative.
Important Notes
Keep these points in mind when calculating your taxable Social Security:
- Only part of your Social Security benefits may be taxable, depending on your income.
- If your total income is below the threshold, your Social Security benefits are not taxable.
- You must report all your income on your tax return to determine if any portion of your Social Security benefits is taxable.
Consult with a tax professional if you have questions about your specific situation.
