One: What Is the Disability Tax Credit – Up to $50,000 Back Explained

What Is the Disability Tax Credit—And what could it mean to add up to fifty thousand back in your pocket? Picture this: You wake up tomorrow with fifty thousand dollars you didn’t earn last week—just because the CRA finally admits your (or that of family member you are caring for) migraines (or ADHD, or bad back) count. That’s the Disability Tax Credit doing its quiet magic. Started in nineteen eighty-five, it refunds up to fifteen thousand per year for marked impairments—like needing crutches to walk, or three hours to dress. Retroactive? Yes—ten full years (if you’ve never claimed before and you qualify). If you earned twenty-five thousand a year, that’s thirty-two thousand back. If you are caring for a family member that qualifies, the refund can be up to fifty thousand dollars. Canadian families have already cashed cheques that size. No lottery ticket required.  The typical claim we are successful with ranges from ten thousand to thirty thousand in tax refunds. Stick around—this guide walks you through every checkbox, doctor fee, and denial trap so you don’t join the seventy percent who botch the application process and become CRA denied. Ready to claim what’s yours? Let’s go.

Two: Who Qualifies for DTC in 2025–2026 – Clear Rules

No Guesswork. If you can’t walk fifty metres without pain, forget your meds three times a week, or take over ninety minutes to shower—even with tools—then yes, you might qualify. CRA calls it a marked restriction in daily stuff: walking, bending, dressing, feeding, hearing, speaking, vision, or mental functions. Doesn’t need to be permanent — just prolonged (fifteen-plus hours weekly of struggle). Twelve real winners: ADHD (planning fails), migraines (bedbound days), chronic fatigue, PTSD, epilepsy, blindness, carpal tunnel (both hands wrecked), fibromyalgia—even hearing loss if you lip-read in crowds. CRA’s handbook spells it out—no IQ cutoff, no MRI, just Part B signed. Grey area? Obesity alone = no. But if it wrecks knees so walking’s torture, your doc says prolonged impairment, boom—you’re in. Retroactive back to ten years if you’ve never filed. Mike skipped it till now—banked eighteen grand. Don’t let vague wording sink you. Next: how to nail the form and process.

Three: Common Qualifying Conditions – Full Breakdown

The CRA doesn’t have an official “approved conditions” list—eligibility depends on how your impairment affects basic activities of daily living (BADL), not the diagnosis alone (except blindness or Type 1 diabetes).

That said, certain conditions commonly lead to approvals when properly documented with the “all or substantially all of the time (at least 90% of the time)” rule.

Below: Eighteen (18) frequent health conditions (2025 data from CRA guidelines and real approvals). For each: linked CRA category, who certifies, key wording that wins, common pitfalls.

Quick Reference Table

Condition Main CRA Category Certifying Practitioner Typical Retro Lump Sum Example Approval Rate Insight
ADHD/ADD Mental Functions Psychologist/Psychiatrist $20,000–$35,000 (10 years) High with cumulative
Anxiety/Depression/PTSD Mental Functions Psychologist/Psychiatrist $15,000–$30,000 Rising in 2025
Autism Spectrum (child/adult) Mental Functions/Speaking Psychologist $25,000+ (incl. child supplement) Very high
Back/Chronic Pain/Arthritis Walking/Dressing MD/OT/Physio $18,000–$28,000 Cumulative common
Blindness/Low Vision Vision Optometrist/MD Auto-qualify Near 100%
Chronic Fatigue/Fibromyalgia Cumulative (multiple) MD $20,000–$40,000 Needs strong examples
Cerebral Palsy Walking/Feeding/Dressing MD/OT/Physio $30,000+ High
Diabetes (Type 1) Life-Sustaining Therapy MD/Nurse Practitioner Auto-qualify Near 100%
Diabetes (Type 2 severe) Life-Sustaining Therapy MD $15,000–$25,000 If 14+ hrs/week
Hearing Loss Hearing Audiologist $12,000–$20,000 Even with aids
Learning Disabilities/Dyslexia Mental Functions Psychologist $10,000–$20,000 Cumulative
Migraines (severe) Mental Functions MD $15,000–$25,000 Bedbound days key
Multiple Sclerosis Walking/Multiple MD/Neurologist $25,000–$45,000 High
Osteoarthritis/Knee Issues Walking MD/Physio $18,000–$30,000 3x longer to walk

Detailed Breakdowns

1. ADHD/ADD Often qualifies under mental functions (adaptive functioning, problem-solving). Winning wording: “Requires substantial prompting/reminders for daily routines 90% of days; forgets medications/tasks despite aids.” Pitfall: Doctors saying “manages with meds”—stress raw impact. Cumulative combo: ADHD + anxiety.

2. Anxiety/Depression/PTSD Mental functions—decision-making, memory under stress. Key: “Avoids basic activities (dressing, feeding) due to panic 90% of time; requires 15+ hrs/week support.” 2025 trend: More approvals with therapist letters.

3. Autism Spectrum Disorder Speaking, mental functions—social cues, adaptive. Children: Often auto-child supplement. Wording: “Needs constant prompting for basic self-care; restricted in communication all/substantially all time.”

4. Chronic Pain/Arthritis/Fibromyalgia Walking, dressing, feeding. Cumulative goldmine: Pain + fatigue = 15+ hrs extra time. Wording: “Takes 3x longer to dress/walk 50m; in pain 90% of time even with meds/aids.”

5. Blindness or Severe Vision Impairment Vision category—auto marked if legally blind. No “even with glasses” excuse.

6. Chronic Fatigue Syndrome/Myalgic Encephalomyelitis Cumulative—fatigue across multiple BADL. Wording: “Bedbound/recovery needed after basic tasks; equivalent to marked restriction.”

7. Diabetes Type 1 Life-sustaining therapy—auto if insulin-dependent (14+ hrs/week monitoring).

8. Hearing Loss (Profound) Hearing—even with aids/cochlear. Wording: “Cannot hear speech in normal conversation 90% of time.”

9. Migraines (Chronic/Severe) Mental functions—if bedbound multiple days/month. Wording: “Incapacitated 4+ days/month; marked restriction in daily activities 90% of time.”

10. Multiple Sclerosis/Parkinson’s Walking, dressing, feeding. Often multiple categories—strong approvals.

11. Osteoporosis/Severe Joint Issues Walking—cannot walk 50m without severe pain/rest.

Many more qualify (e.g., bipolar, schizophrenia, stroke recovery)—focus on impact, not label.

Four: Provincial Differences & Extra Benefits

The federal Disability Tax Credit (DTC) is the same across Canada (base amount around $9,800–$10,100 in 2025, depending on final indexation). But provinces and territories often add their own supplements, linked programs, or indirect perks—meaning thousands more (or key unlocks) depending on where you live.

Some provinces mirror or top-up the federal credit directly; others have no extra DTC but unlock major programs like income assistance or pharmacare. Here’s the 2025 breakdown.

Provincial/Territorial DTC Supplements & Linked Benefits (2025)

Province/Territory Provincial DTC Top-Up (Approx. Annual Credit) Income Reduction? Child Extra? Key Notes / Linked Benefits
Ontario Up to ~$1,600–$1,700 Yes (family income) Yes Automatic if federal DTC approved; stacks nicely
British Columbia None direct N/A No DTC unlocks Pharmacare, transit discounts, RDSP matching
Alberta None direct N/A No DTC helps qualify for AISH (income support program)
Saskatchewan Up to ~$3,000+ Partial Yes One of the highest provincial top-ups
Manitoba Up to ~$1,200 Yes Yes Additional cost-of-living boosts
Quebec Boost via Solidarity Credit (~$1,000–$2,500 extra) Yes (low-income) Yes Filed via Revenu Québec; often overlooked
New Brunswick Up to ~$1,200 Yes Yes Links to low-income seniors’ benefits
Nova Scotia Up to ~$1,200 Yes Yes Poverty reduction links
Prince Edward Island Up to ~$1,000 Yes Yes Linked to social assistance
Newfoundland & Labrador Up to ~$1,500 Partial Yes Physical Disability Tax Credit
Yukon Mirrors federal (~$1,000 extra) No Yes Pioneer Utility Grant access
Northwest Territories Up to ~$1,200 No Yes Income assistance links
Nunavut Up to ~$1,000 No Yes Cost-of-living adjustments

Key Takeaways

  • Biggest direct winners: Saskatchewan (highest top-up), Quebec low-income families, On
  • No direct provincial DTC: BC and Alberta—but DTC approval unlocks powerful indirect benefits like full pharmacare or AISH eligibility.
  • Child boosts: Most provinces add extra for minors; stacks with the federal Child Disability Benefit (up to ~$3,411/year or $284/month in 2025–2026, income-tested).

Federal Child Disability Benefit (Nationwide Stack)

If your child has DTC approval:

  • Up to $3,411/year (July 2025–June 2026), paid monthly (~$284).
  • Income-tested: full amount under ~$81,000 family net income; phases out higher.
  • Retroactive lump sums possible if approved late.

Home Accessibility Tax Credit (HATC) – Federal

DTC holders (or seniors 65+) can claim up to $20,000 in qualifying renovation expenses (ramps, grab bars, wider doors) for a non-refundable credit of up to $3,000 (15%). 2025 max expense limit: $20,000 per home.

Medical Expenses Claim

DTC opens broader deductions (lines 33099/33199), including:

  • T2201 doctor fees
  • Therapy (OT, psychology)
  • Attendant care
  • Devices (wheelchairs, hearing aids)
  • Retroactive claims via T1-ADJ

Province-Specific Tips

  • Ontario: Automatic via Schedule ON428.
  • Quebec: File TP-752.0.14 for Solidarity boost—easy to miss.
  • BC/Alberta: Prioritize RDSP for grants/bonds.
  • Atlantic Provinces: Check for extra low-income supplements.

Your province can add 20–50%+ extra value (or key program access) to the federal DTC. Many miss these because provinces don’t always auto-apply.

Mark how long each task takes. Dressing might take 90+ mins due to tremor. Feeding may require adaptive utensils, or experience spills. Cross any adapting boxes—only raw time counts.

Page 11 Mental functions for everyday life – It is not enough to fail to remember your meds 3+ times a week. Don’t say sometimes—CRA reads sporadic as denial bait.

Significant impairments – You will notice that all through the document it is asked if the health item represents all or substantially all of the time, at least 90% of the time. If your doctor leaves it blank, it is a denial.

Page 14 Cumulative effects of significant limitations – King section of the form. Used to be referred to as line 13. The cumulative effects of significant limitations should have two or more checkmarks. If not, you must have one highly significant impairment, falling into a specific category.

Six: Choosing the Right Doctor – Fees & Tips

CRA accepts certification from qualified medical practitioners only—and the list is specific (updated for 2025). Your family doctor (MD or GP) is usually the easiest and cheapest option, and they know your history.

Who can certify Part B:

  • Medical doctor (MD) or nurse practitioner: all impairment categories
  • Optometrist: vision only
  • Audiologist: hearing only
  • Occupational therapist (OT): walking, feeding, dressing
  • Physiotherapist: walking, dressing
  • Psychologist: mental functions (great for ADHD, anxiety, PTSD)
  • Speech-language pathologist: speaking

Tip: Start with your family doctor or nurse practitioner—they can handle 95% of claims.

Fees: Doctors set their own (CRA doesn’t pay). Current real-world ranges in 2025:

  • Most family doctors: $100–$200
  • Specialists (psychologists, OTs): $150–$300
  • Surgeons $300+
  • Some clinics waive or reduce for low-income patients—ask!
  • The fee is tax-deductible as a medical expense (claim on line 33099 or 33199)

Script to ask your doctor: “Hi Dr. [Name], I need the T2201 form certified for the Disability Tax Credit—it’s a tax thing, not insurance. Can you fill Part B? How much do you charge, and when can I book?”

If they hesitate or charge high: Try a nurse practitioner (often lower fees) or walk-in clinic. Avoid large fees—they’re unnecessary.

Pro move: Bring the blank form (printed) and this CRA digital tool link for doctors: canada.ca/dtc-digital-application—many use it now for faster completion.

Get this done right, and you’re one step from approval. Next: surviving a denial.

Seven: CRA Denial Fixes – Survival Kit & Appeal Template

Don’t panic—many first-time applications get denied (as many as 70% of applications are denied!), often because the form lacks enough detail or the doctor didn’t fully explain the impact. The CRA bases everything on what’s written in Part B of the T2201. Denials aren’t final; most can be fixed with better info.

Common CRA Denial Reasons (based on CRA feedback and real cases in 2025):

  • No clear start date for when symptoms began (hurts retroactive claims).
  • The “all or substantially all of the time (at least 90% of the time)” box isn’t checked in the relevant category.
  • Insufficient description of how the impairment markedly restricts daily activities (e.g., takes 3x longer or can’t do it at all, even with aids).
  • Duration not marked as prolonged (expected to last years).
  • Cumulative effects missed (when two milder restrictions add up to 15+ hours/week of extra time/support).
  • Incomplete form—missing signature, dates, or practitioner details.

If denied, you’ll get a Notice of Determination explaining why.

What to do next:

  1. Call CRA at 1-800-959-8281 → discuss and clarify.
  2. Request a review → send more details (updated letter from doctor, examples of daily impact).
  3. Submit a new T2201 → with stronger wording if your situation changed.
  4. File a formal objection → within 90 days of the notice date (use My Account, mail, or Form T400A).

Re: Objection to DTC Denial – Notice of Determination dated [date] – SIN: [your SIN]

Dear Sir/Madam,

I formally object to the denial of my Disability Tax Credit application.

The impairment [describe briefly, e.g., severe anxiety and mobility issues] causes marked restrictions all or substantially all of the time in [categories, e.g., mental functions and walking].

Attached: Updated T2201 certification from [doctor name] with detailed examples of daily impacts (e.g., requires 3x longer to dress, forgets essential tasks 90% of days despite aids).

This meets CRA criteria under section 118.3 of the Income Tax Act. Please approve retroactively from [year symptoms started].

Sincerely, [Your Name] [Phone]

Many denials flip on resubmission with clearer details. Hang in there.

Eight: Hidden DTC Hacks Most Miss

Add Your Heading Text Here

These lesser-known strategies can multiply your DTC benefits—most guides skip them, but they add thousands for approved families.

  1. Transfer to a Supporting Family Member If you have low or no taxable income, transfer the full disability amount to your spouse, parent, child, sibling, or other eligible dependant. They claim it on their return—even if you never paid tax. No extra form needed once approved; just enter it on Schedule 1.
  2. Open a Registered Disability Savings Plan (RDSP) DTC approval unlocks government matches: Contribute $1,500 → get up to $3,500 free grant yearly (300% match for low-income). Plus $1,000 bond no contribution required if family income under ~$55k. Lifetime max $200,000 in grants/bonds. Starts compounding tax-free.
  3. Claim Retroactive Adjustments Up to 10 Years Tick the box on T2201 for CRA to auto-adjust past returns. If missed, file T1-ADJ forms yourself—potentially $20,000–$50,000 lump sum depending on income history.
  4. Stack with Provincial Credits and Other Benefits DTC auto-qualifies you for extras like Child Disability Benefit ($200+/month per child), medical expense deductions, home accessibility renos ($10k+ credit), and in some provinces additional top-ups (e.g., Ontario Disability Support).
  5. Cumulative Effects Rule for “Milder” Conditions No single marked restriction? Combine two significant ones (e.g., moderate anxiety + chronic pain = 15+ hours/week extra time/support). Check the cumulative box on page 15—huge for fibromyalgia, ADHD combos.
  6. Use DTC as Income Proof Approved letter counts as “income” for mortgages, loans, or rentals—banks accept it to boost qualifying amounts.

These hacks often double or triple the real value. Many miss them and leave money on the table.

Nine: Real Case Studies – No Fluff

Real people, real conditions, real money back. These anonymized examples (based on common approved claims we’ve seen) show what’s possible—no hype, just results.

Anna, 48, Chronic Migraines & Anxiety (Ontario) Denied twice on her own because the doctor wrote “occasional migraines.” We helped rephrase to “bedbound 4+ days/month, marked restriction in mental functions all or substantially all of the time.” Approved retroactively 8 years. Lump sum: $28,400. Now transfers unused amount to her husband.

David, 35, ADHD & Depression (British Columbia) Never thought he qualified—”I work part-time.” Cumulative effects rule kicked in: memory issues + fatigue = 15+ hours/week extra support. Psychologist certified mental functions category. Approved indefinitely. Retro 10 years: $32,000 back, plus opened RDSP with grants.

Sarah & Daughter Lily, 7, Autism Spectrum (Alberta) Mom applied for child DTC. Marked restrictions in speaking + mental functions (90% of time needs prompts for basic tasks). Approved from age 3. Retro lump sum: $22,000 (mostly to mom as supporting parent) + monthly Child Disability Benefit started.

Mike, 62, Hearing Loss & Arthritis (Nova Scotia) Hard of hearing even with aids + can’t walk 50m without pain. Audiologist + GP certified hearing + walking. Approved after initial denial (missed 90% box). Appeal won in 60 days. Retro: $18,500.

Rachel, 29, Type 1 Diabetes (Quebec) Life-sustaining therapy (insulin 14+ hours/week monitoring). Auto-qualifier once worded right. Approved indefinitely. Retro 6 years: $15,200 + provincial top-up.

These aren’t rare wins—strong wording + right checkboxes make the difference. Many DIY folks leave thousands behind.

Twelve: Retroactive Calculator & Real Refund Examples

Wondering exactly how much you could get back? The Disability Tax Credit (DTC) is a non-refundable tax credit, meaning it reduces your federal (15%) and provincial tax bill. If it reduces tax to zero, you get a refund of overpaid tax—often a large lump sum retroactively.  If you are caring for a family member, you may be able to transfer this to you.

2025 Federal Amounts (Indexed for Inflation)

  • Base amount (adults 18+) — approximately $9,872 (federal credit ~$1,481 at 15%).
  • Supplement for children under 18 — up to $5,758–$5,914 extra (federal credit ~$864–$887).
  • Provincial — adds 5–10% more depending on province (see Provincial Differences section).

Simple Retro Calculator Table (Estimate Your Lump Sum Refund)

Assumes average tax bracket where full credit becomes refundable (common for many claimants). Actual depends on your past income/tax owed—higher income = bigger refund.

Number of Retro Years Adult (No Child Supplement) With Child Supplement High Provincial Top-Up (e.g., SK, ON) First-Time 10-Year Max Example
1 year (current) $1,500–$2,000 $2,200–$2,800 $2,000–$3,000 –
6 years $9,000–$12,000 $13,000–$17,000 $12,000–$18,000 –
8 years $12,000–$16,000 $17,000–$22,000 $16,000–$24,000 –
10 years (first claim) $15,000–$20,000 $22,000–$28,000 $20,000–$30,000 $30,000–$50,000+
How the Math Works (Step-by-Step)
  • Federal credit = 15% × (base $9,872 + child supplement if applicable).
  • Provincial credit = province rate × same amounts.
  • Total yearly credit = federal + provincial.
  • Retro lump = total yearly × eligible years (up to 10 if never claimed).
  • Actual refund = amount of past tax overpaid (often close to full credit for moderate incomes).

Real Examples (2025 Estimates, Anonymized Cases)

Example 1: Single Adult, Moderate Income, Ontario (6 Years Retro)

  • Federal: ~$1,481/year
  • Ontario top-up: ~$500–$600/year
  • Total/year: ~$2,000
  • Lump sum: ~$12,000
Example 2: Parent Claiming for Child Under 18, Quebec Low-Income (8 Years)
  • Federal base + supplement: ~$2,300/year
  • Quebec solidarity boost: extra $1,000+
  • Child Disability Benefit retro: ~$20,000+ monthly backpay
  • Total lump: ~$30,000+
Example 3: Married High-Earner, BC (10-Year First Claim)
  • Federal only (no provincial DTC): ~$1,481/year
  • Higher tax bracket = full credit refundable
  • Lump: ~$15,000 (plus RDSP grants unlocked)
Example 4: Low-Income Adult, Saskatchewan (6 Years)
  • Federal: ~$1,481
  • SK high top-up: ~$800+
  • Total/year: ~$2,300
  • Lump: ~$14,000
Example 5: Denied Then Approved on Appeal, Alberta (Retro from Symptom Start)
  • Added 4 extra years with better wording
  • From $10,000 → $22,000 lump

These are conservative—many get $20,000–$50,000+ when combining retro, provincial, and linked benefits. These amounts do not include the scenario where you are claiming a family member.

Thirteen: What Happens After Approval – Next Steps

Congratulations—you’ve been approved for the Disability Tax Credit! This is the part most guides skip, but it’s where the real financial benefits start flowing. Here’s exactly what happens next, step by step, in 2025–2026.
1. You Receive the Notice of Determination
  • CRA mails (or posts to My Account) an official Notice of Determination letter.
  • It states: Approved from [start year] indefinitely (or until reassessment).
  • Retroactive years listed + exact credit amount per year.
  • Timeline: 8–16 weeks after mailing T2201 (faster if digital pilot in your region).
2. Retroactive Lump Sum Payment
  • CRA automatically reassesses past returns (up to 10 years if first claim).
  • Cheque or direct deposit arrives 4–12 weeks after notice.
  • Average: $20,000–$40,000 (depends on income, years, province).
  • Taxable? No—the credit is non-refundable, but any refund is tax-free cash.
  • Provincial top-up? Usually separate cheque or added to federal.
3. Claiming on Future Tax Returns
  • Once approved, claim yearly on line 31600 (yourself) or line 31800 (dependant) of T1 return.
  • Amount: ~$9,000–$9,500 federal base (2025 indexed) + provincial.
  • Software (TurboTax, Wealthsimple) auto-pulls if you link My Account.

No re-application needed unless condition changes significantly.

4. Open a Registered Disability Savings Plan (RDSP) – The Big Multiplier
  • DTC approval is the key to unlock government grants/bonds.
  • Steps:
  1. Choose a bank (RBC, TD, BMO all offer—compare fees).
  2. Open RDSP account (bring DTC notice + SIN).
  3. Contribute (even $1 triggers bond).
5. If Your Condition Worsens – Reassessment
  • Impairment more severe? Request reassessment for earlier start date or new categories.
  • Submit new T2201 (no fee) + doctor letter.
  • Common: Add cumulative effects later → bigger retro.
6. Transfer to Family Member
  • Low income? Transfer unused credit to spouse/parent/child (line 32600).
  • No extra form—claim directly on their return.
7. Protecting Your Approval
  • CRA may review randomly (audit)—keep doctor records 6+ years.
  • Report major improvements (rarely reduces credit).
  • Move provinces? Credit follows—notify CRA for provincial switch.
8. Stack with Other Benefits
  • Child Disability Benefit: Monthly payments start auto (~$277/month).
  • Medical expenses: Claim attendant care, devices retroactively.
  • HATC: Up to $3,000 cash for home renos.

Real timeline example: Approved March 2026 → retro cheque May → RDSP open June → first grant October.

Many stop at “approved”—then miss RDSP grants worth more than the DTC itself over time.

Fourteen: How DTC Stacks with EI, CPP & More (Bonus)

Good news: These programs are designed to work together—you can often receive multiple at once without one cancelling the other. Here’s the straightforward breakdown for 2025:

Disability Tax Credit (DTC) + CPP Disability (CPP-D)
  • Completely independent programs (DTC = CRA tax credit; CPP-D = Service Canada monthly pension).
  • You can get both simultaneously—no offset or reduction.
  • Many people on CPP-D also claim DTC (and vice versa)—DTC approval can even help strengthen a CPP-D application by proving severe impairment.
  • Stack benefit: DTC reduces your tax on CPP-D payments + unlocks RDSP grants.
Disability Tax Credit (DTC) + EI Sickness Benefits
  • Yes, you can receive EI sickness (up to 26 weeks temporary support) while approved for DTC.
  • DTC is a permanent tax credit; EI sickness is short-term income replacement.
  • No direct interaction—EI sickness payments are taxable, and DTC can reduce tax owed on them.
  • Note: If your condition becomes prolonged, transition to CPP-D or other long-term options.
All Three Together?
  • Possible in overlap periods (e.g., waiting for CPP-D approval while on EI sickness and claiming DTC retroactively).
  • Real example: Someone off work sick → EI sickness pays weekly → gets DTC approved → reduces tax on EI + opens RDSP → later switches to CPP-D seamlessly.

Bottom line: These aren’t “either/or”—stacking them maximizes support. Many leave money behind by not claiming all they’re entitled to.

Fifteen: Key CRA Terms Glossary

Navigating the Disability Tax Credit means understanding CRA-specific language. Here’s a plain-English glossary of the most important terms (with direct CRA definitions from the 2025 T2201 and Income Tax Act section 118.3).

Auto-qualifier if you need at least 14 hours/week (averaged over months) on therapy to sustain life (e.g., insulin management for Type 1 diabetes, dialysis, chest physiotherapy for cystic fibrosis). Includes prep, monitoring, recovery.

Cannot do the activity at all, OR
Takes three times longer than average person of similar age, OR
Requires exceptional daily help/adaptation. Even with aids/medication—must be 90% of the time.

Official CRA letter confirming approval/denial. States start date, categories, and retro years. Keep forever—needed for RDSP, provincial claims.

Must have lasted (or expected to last) at least 12 continuous months. “Expected to last” allows approvals for progressive conditions.

CRA reassessing past tax returns (up to 10 years) to apply DTC. Results in lump-sum refund cheque.

Less severe than marked—used only for cumulative claims. Takes considerably longer or requires help, but not 3x or 90%.

The official form—Part A (taxpayer) + Part B (medical practitioner certification). Only current version accepted.

Approved person with low/no income can transfer unused credit to supporting spouse, parent, child, grandparent, sibling, etc. (line 32600 or dependant lines).

Understanding these terms is 80% of winning approval. Misuse one (like checking “sometimes” instead of 90%), and it’s denial city.

Sixteen: Frequently Asked Questions (FAQ)

Our zero-risk free assessment reviews your details confidentially—no obligation.

The DTC is a non-refundable federal tax credit that reduces income tax for people with severe and prolonged impairments (or their supporting family members). It can result in retroactive refunds up to $50,000+ and unlocks other benefits like RDSP grants.

Yes—many approved people work full-time or part-time. Eligibility depends on your impairment’s impact on daily activities (marked restriction 90% of the time), not employment status.

No—the DTC is independent and doesn’t reduce CPP-D, EI sickness, or provincial supports (except rare cases like Alberta AISH offsets). It often complements them.

Find another qualified practitioner (nurse practitioner, psychologist, OT, etc.—list in Picking the Right Medical Pro section). Bring examples of winning wording; many switch doctors successfully.

Up to 10 years if this is your first approval (back to 2016 for 2026 claims). CRA auto-adjusts if you check the box on T2201.

Yes—for any age if they meet criteria. Under 18 adds supplement (~$5,900 federal). Over 18: transfer unused credit to parents if low income.

No—refunds and credits are tax-free cash.

8–16 weeks average (longer during peaks). Check status via My Account or call 1-800-959-8281.

Yes—new evidence, updated condition, or better wording often wins on reapplication or appeal.

Yes—if aged 18–64 and income-tested, DTC approval is the gateway for the $200/month CDB (starting July 2025).

Yes—unused amount transfers to supporting spouse/common-law, parents, children, siblings, etc.

Doctor fees for T2201, attendant care, devices, therapy—retroactively.

No—low/no income families transfer to supporters or get provincial top-ups.

Quebec has solidarity tax credit boost instead of provincial DTC—often bigger for low-income.

Yes—ADHD, anxiety, depression, PTSD commonly approve under mental functions (memory, adaptive, problem-solving).

Type 2: if severe insulin management (14+ hrs/week). Chronic pain: often cumulative effects.

Take DTC notice to any bank—unlocks up to $3,500/year grants + $1,000 bond.

Yes—unlocks Home Accessibility Tax Credit (up to $3,000 cash back).

Yes—no age limit, though some linked benefits change.

Rarely affects past approvals; report major changes to CRA.

Yes—claim on medical expenses (line 33099/33199).

Yes—via My Account “Submit Documents” (faster processing).

Usually vague wording—missing “90% of time” or cumulative details.

No reduction—stacks freely.

Yes—if Canadian tax resident with SIN.

Still apply—DTC can trigger refunds even with zero income.

Near-automatic with proper certification.

Two+ significant restrictions = 15+ hrs/week extra time/support.

Yes—CRA reassesses unfiled returns.
