Quick Answer
On-call pay is compensation for being available to work outside normal hours. It's taxed as regular wages — if you earn $50/day on-call pay (about $13,000 annually), expect to pay roughly $3,250 in federal taxes (22% bracket) plus $995 in FICA taxes, leaving approximately $8,755 take-home.

Employees who receive on-call or standby pay and need to understand the compensation and tax implications
What is on-call pay?
On-call pay (also called standby pay or availability pay) compensates employees for being available to respond to work emergencies or calls outside their regular schedule. You're typically required to remain reachable and respond within a specified timeframe, but you're not actively working unless called in.
According to the Fair Labor Standards Act (FLSA), on-call time must be compensated when your freedom is significantly restricted. Most employers pay a flat daily or hourly rate for on-call availability, separate from any pay you receive if actually called to work.
How on-call pay is taxed
On-call pay is treated as regular wages for all tax purposes. There's no special tax treatment — it's subject to federal income tax, state income tax, Social Security tax (6.2%), and Medicare tax (1.45%) just like your regular salary.
Example: IT professional with on-call duties
Sarah works in IT earning $75,000 annually and receives $50 per day for weekend on-call coverage (about 52 weekends = $2,600 annually). Here's the tax breakdown:
The on-call pay increases her total tax burden by $771, leaving $1,829 in additional take-home pay.
Different types of on-call arrangements
Standby pay only: You receive compensation just for being available, whether called or not. This is always taxable as regular wages.
Call-in pay: Additional compensation when you're actually called to work during on-call periods. This may be at regular rates, overtime rates, or special call-in rates, all taxed as regular wages.
Restricted on-call: When your activities are severely limited (must stay within 30 minutes of workplace), you may be entitled to minimum wage for all on-call hours under FLSA.
How withholding works for on-call pay
Most employers include on-call pay in your regular paycheck, so withholding follows your normal W-4 settings. If paid separately, employers typically withhold at the 22% supplemental wage rate.
For consistent on-call schedules, some employers adjust your regular withholding to account for the additional income throughout the year.
Key factors affecting your on-call pay taxes
What you should do
Calculate your estimated annual on-call pay and adjust your W-4 if necessary to avoid under-withholding. If you receive significant on-call pay irregularly, consider setting aside 25-30% for taxes.
Key takeaway: On-call pay is taxed exactly like regular wages with no special exemptions. Budget for approximately 25-35% in total taxes depending on your bracket.

Key Takeaway: On-call pay is taxed as regular wages with no special treatment — expect to pay your normal tax rates on all on-call compensation received.

Working parents who take on-call duties for extra income and need to understand the family financial impact
On-call pay considerations for families
Many parents take on-call duties to supplement family income, but it's important to understand both the tax implications and practical considerations for your household budget.
Impact on family tax benefits
On-call pay increases your adjusted gross income, which can affect eligibility for family tax credits:
Example: A family earning $58,000 who adds $4,000 in on-call pay might see their EITC reduced by $200-400, partially offsetting the additional income.
Budgeting with irregular on-call income
Since on-call pay can be unpredictable, consider:
Childcare considerations
Remember that on-call duties may require childcare arrangements, which could offset some of the financial benefit. However, childcare expenses for work-related on-call duties may qualify for the Child and Dependent Care Credit.
Key takeaway: For families, factor in potential reductions to tax credits when calculating the net benefit of on-call pay opportunities.
Key Takeaway: Families should consider how on-call pay affects tax credits and budget for the irregular nature of this additional income when planning finances.

Older workers considering on-call arrangements as they transition toward retirement
On-call pay for pre-retirees and retirees
If you're nearing retirement or already retired, on-call work can provide valuable supplemental income, but there are specific considerations for your age group.
Social Security implications
For workers still contributing to Social Security, on-call pay counts toward your earnings record and future benefit calculations. If you're already at the Social Security wage base ($176,100 in 2026), you won't pay Social Security tax on on-call pay but will still owe Medicare taxes.
For retirees collecting Social Security, on-call earnings count toward the earnings test if you're under full retirement age. In 2026, you can earn up to $22,320 without affecting benefits, but earnings above this reduce your Social Security payments.
Medicare considerations
On-call pay increases your modified adjusted gross income (MAGI), which could trigger Income-Related Monthly Adjustment Amounts (IRMAA) surcharges on Medicare Part B and Part D premiums. These surcharges apply two years later, so 2026 on-call income affects 2028 Medicare premiums.
Retirement account opportunities
If you're still working, on-call pay provides earned income that allows you to contribute to IRAs. Workers 50+ can contribute up to $8,000 to an IRA in 2026, potentially reducing the tax impact of on-call earnings.
Flexible transition strategy
On-call arrangements can be ideal for transitioning to retirement, allowing you to reduce your regular schedule while maintaining some income and benefits. Just ensure you understand how this affects your overall retirement tax planning.
Key takeaway: Pre-retirees should consider how on-call pay affects Social Security benefits, Medicare premiums, and retirement account contribution opportunities.
Key Takeaway: For those near retirement, on-call pay offers flexible income but may impact Social Security benefits and future Medicare premiums based on earnings thresholds.
