Whether BPD Qualifies for the Disability Tax Credit

Borderline Personality Disorder (BPD) can may have access to for the Disability Tax Credit (DTC), but only if it causes severe and prolonged impairment in basic activities of daily living. The Canada Revenue Agency (CRA) does not have a list of conditions that automatically may have access to or disqualify. Instead, they assess whether your condition — in this case, BPD — limits you markedly in at least one of the basic activities: walking, dressing, eating, continence, mental functions needed for everyday life, or communicating.

The key word is markedly. This means you need support from another person, or you take significantly longer than a person without the condition, or the activity is impossible for you. For BPD, the impairment usually centers on mental functions — specifically, the ability to perceive, think, and remember; manage behavior and emotions; or sustain attention and concentrate.

Many people with BPD do not meet the DTC threshold because their symptoms are manageable with treatment, or the impairment does not affect basic daily activities in a way the CRA recognizes. Others do may have access to because BPD causes severe emotional dysregulation, impulsive behavior, or difficulty with self-care that genuinely prevents them from functioning independently.

Key Takeaways

  • The CRA assesses BPD for the DTC based on whether it causes marked impairment in basic activities of daily living, not on diagnosis alone.
  • Mental function impairment — difficulty managing emotions, controlling behavior, or concentrating — is the most common basis for DTC approval with BPD.
  • You need medical documentation from a doctor or psychologist describing how BPD limits your daily functioning, not just a diagnosis.
  • The DTC process requires Form T2201 signed by a medical practitioner, and the CRA often requests additional detail about how your condition affects specific activities.
  • If the CRA denies your process, you can request reconsideration or file a Notice of Objection within one year of the decision.

What the CRA Means by "Marked Impairment"

The CRA uses a specific legal test for marked impairment. You must be unable to perform a basic activity of daily living, or you must require an inordinate amount of time to perform it, or you must require extensive support from another person to perform it. For someone with BPD, this usually means one of three things: you cannot manage your emotions or behavior without constant supervision or intervention; you cannot perform self-care tasks like bathing, dressing, or eating because emotional dysregulation interferes; or you cannot concentrate or remember instructions well enough to carry out routine tasks.

The CRA does not count occasional difficulty or the need for occasional help. If you have a bad week and cannot get out of bed, that is not enough. If you have bad weeks regularly and cannot function without support during those periods, and this pattern is ongoing, that moves closer to marked impairment. The condition must be severe and prolonged — lasting or expected to last at least 12 months.

Many people with BPD experience severe symptoms but manage them through therapy, medication, or both. If treatment allows you to function independently most of the time, the CRA may conclude that your impairment is not marked, even though you have the diagnosis. This is a common reason for denial.

Medical Evidence the CRA Requires

The CRA will not approve the DTC based on a diagnosis alone. You need a medical practitioner — a doctor, psychiatrist, or psychologist — to complete Form T2201 and describe specifically how BPD limits your daily functioning. The form asks the practitioner to check boxes for which basic activities are affected and to provide details about the nature and frequency of the impairment.

For BPD, the most persuasive evidence includes: a description of how emotional dysregulation or impulsive behavior prevents you from performing self-care or household tasks; documentation of how your condition affects your ability to manage your own behavior in social or work settings; notes about concentration or memory problems that interfere with following instructions or completing tasks; and a timeline showing that this impairment has been present for at least 12 months or is expected to continue for that long.

The practitioner does not need to write a lengthy letter. The T2201 form itself is the official document. However, if the CRA requests additional information — which they often do for mental health conditions — a supporting letter from your doctor or therapist explaining the functional limitations can strengthen your case. This letter should focus on what you cannot do, not on symptoms or diagnosis.

how the process works for the Disability Tax Credit with BPD

Start by asking your doctor, psychiatrist, or psychologist whether they believe your BPD causes marked impairment in a basic activity of daily living. If they say yes, ask them to complete Form T2201. You can read the form from the CRA website or request it by mail. The practitioner must sign the form; an unsigned form will be rejected.

Once the form is completed and signed, mail it to the CRA along with your tax return for the year you are claiming the credit. You can also submit it separately if you are not filing a return that year. Include your Social Insurance Number (SIN) on the form so the CRA can match it to your account. Keep a copy for your records.

The CRA will review the form and either approve or deny your claim. If they approve, the DTC becomes available for the year you applied and retroactively for up to 10 prior years if you meet the criteria for those years as well. If they deny it, you will receive a letter explaining why. You then have one year from the date of the decision to request reconsideration or file a Notice of Objection.

Common Reasons the CRA Denies BPD Claims

The most frequent reason for denial is that the medical evidence does not clearly describe marked impairment in a basic activity. The practitioner may have written only that the person has BPD and struggles with emotions, without explaining how this prevents them from dressing, eating, managing hygiene, or performing other daily tasks. The CRA needs concrete functional limitations, not diagnostic labels.

A second common reason is that the impairment is not deemed severe enough. If the person is working full-time, managing a household, or functioning independently most of the time, the CRA may conclude that the condition, while real, does not meet the marked impairment threshold. This is especially true if the person's symptoms are well-controlled with medication or therapy.

A third reason is that the form is incomplete or unsigned. If the practitioner did not answer all the relevant questions or did not sign the form, the CRA will return it and ask for corrections. This delays the decision but does not prevent approval if the evidence supports it.

What Happens If the CRA Denies Your Claim

If the CRA denies your DTC process, you will receive a letter dated with the decision. You have one year from that date to request reconsideration or file a Notice of Objection. Requesting reconsideration is simpler: you write to the CRA, explain why you believe the decision was wrong, and include any new or additional medical evidence. This is not a formal appeal; it is a request for the CRA to review the file again.

If reconsideration does not work, or if you prefer a more formal process, you can file a Notice of Objection. This is a legal document that starts the objection process. You must file it within one year of the CRA's decision date. The CRA will then assign the file to a different reviewer, who will examine the evidence again. If you disagree with the objection decision, you can appeal to the Tax Court of Canada, but this requires legal representation and is rare for DTC cases.

Before you object, consider whether new medical evidence would help. If your condition has worsened since the original process, or if you have new documentation from a practitioner describing functional limitations more clearly, submit that with your objection. The CRA often reverses denials when the second submission includes better evidence of marked impairment.

How the Disability Tax Credit Works Once Approved

Once the CRA approves your DTC, you become may be able to access for the Disability Tax Credit itself and for the Registered Disability Savings Plan (RDSP). The DTC is a non-refundable tax credit, which means it reduces the tax you owe but does not result in a refund if you have no tax owing. However, if you have little or no income, you can transfer the credit to a spouse, common-law partner, or parent who can use it against their tax.

The RDSP is more valuable for many people. It is a registered savings account that allows you or a family member to contribute up to $2,500 per year (with a lifetime limit of $50,000). The government matches contributions through the Canada Disability Savings Grant and may add money through the Canada Disability Savings Bond. Money in the RDSP grows tax-free and can be withdrawn later without affecting most government benefits.

The DTC approval is usually valid for 10 years from the date of approval, after which you may need to reapply. The CRA will notify you before the approval expires. If your condition improves significantly, you can also notify the CRA to end the approval early.

Frequently Asked Questions

Can I explore for the DTC if I am working or in school?

Yes. The CRA does not require you to be unemployed or unable to work. What matters is whether BPD causes marked impairment in a basic activity of daily living. Some people work despite marked impairment in other areas — for example, you might work part-time but be unable to manage self-care without support. The key is the functional limitation, not your employment status.

What if my doctor says I have BPD but is unsure whether it qualifies for the DTC?

Ask your doctor to focus on the functional impact rather than the diagnosis. Provide them with a copy of Form T2201 and highlight the questions about basic activities. Explain specifically how BPD affects your daily life — for example, "I cannot manage my emotions without my therapist's support" or "I cannot concentrate on tasks for more than 15 minutes." This helps the practitioner understand what the CRA is looking for.

If I was denied once, can I explore again?

Yes, but only if your condition has worsened or if you have new medical evidence. Submitting the same form and evidence a second time will likely result in the same denial. If you reapply, include updated documentation from your practitioner describing how your functional limitations have changed or become more severe since the first process.

Does the DTC affect other benefits I receive?

The DTC itself does not affect most government benefits. However, money you withdraw from an RDSP may affect means-tested benefits like Supplemental Income Support or housing information in some provinces. Check with your provincial social services office before opening an RDSP if you receive income-tested benefits.

How long does the CRA take to decide on a DTC process?

The CRA typically takes 4 to 6 months to review a DTC process, though this varies. If the form is incomplete or the CRA needs more information, the timeline extends. You can call the CRA to check the status of your process after 4 months if you have not heard back.
