Tax Bunching for Caregivers: How to Time Medical Expenses to Actually Get the Deduction
A family spends roughly $14,000 a year on a parent’s care — steady, predictable, and just under the line that would make any of it deductible. Spread evenly across two years, none of it clears the 7.5% AGI floor, so the medical deduction is zero in both years. Bunched into one year, the same total spending breaks through the floor and produces a real deduction in the year it lands. That is the entire idea behind bunching: not spending more, but timing deferrable costs so they cross a threshold instead of straddling it. Here is how to do it deliberately.
Why bunching works for caregiving costs
Two thresholds make timing matter. First, unreimbursed medical expenses are deductible only above 7.5% of AGI (per IRS Publication 502). Second, you only benefit from itemizing if your total itemized deductions beat the standard deduction — $16,100 single, $24,150 head of household, $32,200 married filing jointly for 2026, with an age-65 addition of $2,050 (single/HOH) or $1,650 per spouse (MFJ) (per IRS Publication 501). The mechanics of clearing the floor are covered in how the 7.5% AGI floor absorbs your first thousands in medical expenses.
When ongoing care costs sit near but not over those thresholds every year, bunching concentrates the deferrable portion into alternating years — clearing the floor and the standard deduction in the “on” year, and taking the standard deduction in the “off” year.
Step 1 — Calculate your floor and your gap
Take your expected AGI and multiply by 7.5%. That is the floor. Subtract your recurring (non-deferrable) qualified medical expenses from the floor to find your gap — the amount of additional medical spending you would need to bring into the year to start producing a deduction.
AGI $100,000 → floor = 0.075 × $100,000 = $7,500.
Recurring care costs this year: $6,000.
Gap: $7,500 − $6,000 = $1,500. Until you exceed $7,500 in total qualified expenses, the deduction is $0. Bring more than $1,500 of additional deferrable expense into the year and every dollar beyond $7,500 becomes deductible.
Step 2 — Inventory which expenses are deferrable
Bunching only works on costs you control the timing of. Sort your caregiving and household medical expenses into two buckets:
- Deferrable / accelerable: dental work and implants, hearing aids, eyeglasses and exams, elective procedures, planned home modifications made for medical reasons (ramps, grab bars, widened doorways), and prepayable therapy or care packages.
- Fixed: ongoing in-home aide hours, monthly facility charges, recurring prescriptions. These land when they land — you build the plan around them, not with them.
Step 3 — Pick the “on” year and concentrate
Choose the year to bunch into — usually the year with higher fixed care costs, lower expected AGI, or a large one-time medical expense already scheduled. Pull deferrable costs forward into that year (or push them from the prior year). The goal is to make the “on” year clear both the 7.5% floor and the standard deduction, while the “off” year falls back to the standard deduction cleanly.
Step 4 — Confirm the bunched year actually beats the standard deduction
Clearing the floor produces a deductible medical amount; it does not guarantee a benefit. Add the deductible medical amount to your other itemized deductions — state and local taxes (capped at $10,000), mortgage interest, charitable gifts — and compare the total to your standard deduction. If the itemized total wins, the bunching worked. If it still falls short, consider also bunching charitable contributions into the same year. The full breakeven walk-through is in itemize or standard deduction: the math caregiving families get wrong.
AGI $100,000. Bunched-year qualified medical expenses: $18,000.
Floor: $7,500. Deductible medical amount: $18,000 − $7,500 = $10,500.
Add SALT $10,000 + mortgage interest $4,000 = itemized total $24,500.
Single standard deduction 2026: $16,100. Itemizing wins by $8,400; at a 22% rate the bunching year saves roughly 0.22 × $8,400 = $1,848 more than the standard deduction would. The off year takes the $16,100 standard deduction.
Step 5 — Document medical necessity as you go
Whether an expense is deductible at all often turns on medical necessity. Keep the physician’s plan of care, prescriptions, and the chronically-ill certification with your receipts — especially for in-home care and home modifications. The medical-versus-custodial boundary that decides what even enters your bunching total is covered in which nursing home and care costs are tax deductible.
When bunching is not the right tool
If your AGI is high enough that the floor consumes most of any realistic medical spending, or if your state offers a caregiver credit that does not require itemizing, the medical deduction may not be where the benefit is. State caregiver credits in particular often apply regardless of whether you itemize — making them the safety net when the federal medical path closes. Bunching is a timing tool for families who are close to the thresholds, not a way to manufacture a deduction that the numbers do not support.
