ISP-1640 CPP Child Rearing Provision: Fill Online

What is ISP-1640 CPP child rearing provision?

Years with no or low earnings normally lower a Canada Pension Plan (CPP) benefit. The Child Rearing Provision (CRP) helps you keep your level of earnings for the time you stopped working or had lower earnings while caring for a child under seven, which can help you qualify for a benefit or raise its amount. Form ISP-1640 is how you ask for it.

The form's information sheet says to complete it if you have applied for or are receiving a CPP retirement pension or disability benefit and meet the criteria: you or your current or former spouse or common-law partner received the Family Allowance or were eligible for the Canada Child Benefit, and you had no or low earnings while you were the primary caregiver of a child under 7 born after December 31, 1958. For a CPP death or survivor benefit, the estate or the person handling the deceased's affairs can complete it for them.

FileIt walks you through the children table, the Family Allowance and Canada Child Benefit questions and the optional parts (a spouse's waiver, completing it for someone who has died, a witness), then prints everything into Service Canada's own PDF, with your SIN at the top of each form page. The form asks for a pen signature, so you print it, sign it and mail it or drop it off yourself. FileIt never submits anything.

Who fills it: Parents who have applied for or receive a CPP retirement pension or disability benefit, or the estate of a deceased parent

How to fill out ISP-1640 CPP child rearing provision, step by step

1 Section A — Information about you

Your SIN, optional salutation, name, address on one line, telephone number and optional email address. If you are requesting the provision for a person who has died, put their SIN and name here instead of yours.

2 Section B — The children

List every child regardless of their current age or if they have died: full name, SIN, date of birth and, if born outside Canada, the date they entered Canada. The form has four rows; attach a sheet for more. Without a SIN, Service Canada may ask for a copy of the birth certificate.

3 Section C — Family Allowance and Canada Child Benefit

C1 asks whether you or your current or former spouse or partner received the Family Allowance, and whether either of you received or was eligible for the Canada Child Benefit, and who. C2 lists periods without those benefits, C3 asks whether you were the primary caregiver while the children were under 7, and C4 lists periods when you were not. Annex A at the end of the form shows what to complete in each situation.

4 Section D — Waiver of rights

Only if you were the primary caregiver but your current or former spouse or partner received the Family Allowance. They complete and sign D1 to give up their right to the provision for those children and periods, and the form warns the waiver cannot be reversed. If you apply for yourself without a waiver, or for a deceased person, D1 is not signed.

5 Section E — Declaration and signature

Sign and date in pen. If you complete the form for someone who has died, add your own name, telephone number and address. If you sign with a mark, a witness completes E2.

Common mistakes to avoid

Leaving out children who are now adults or have died. The form asks for all of them.
Forgetting the SIN at the top of each page and on every sheet you add.
Signing with anything other than a pen, or not signing at all.
Having your spouse sign the D1 waiver when you are requesting the provision for yourself without one, or for a deceased person.
Sending original documents. The form asks for readable copies of every page, with your SIN on them.
Listing a child born before 1959: the provision covers children born after December 31, 1958.

After you fill it out

Print the PDF, sign and date section E in pen, and have your spouse or partner sign D1 if a waiver applies. Go through the checklist in Annex B.

Mail it to the Service Canada office for your province or territory, listed on the last page of the form (from outside Canada, the office for the province where you last lived), or drop it off at a Service Canada Centre. Include copies of any supporting documents.

The form says Service Canada will ask for more information or documents if needed, and will tell you whether you qualify once it has everything. Keep the filled copy in your FileIt vault.

ISP-1640 CPP child rearing provision: frequently asked questions

What does the CPP Child Rearing Provision do?

It helps you keep your level of earnings for the periods you stopped working or earned less while caring for a child under seven, so those years don't lower your CPP benefit. It can help you qualify for a benefit or receive a higher amount.

Who qualifies?

The form says you or your current or former spouse or common-law partner must have received the Family Allowance or been eligible for the Canada Child Benefit, and you must have had no or low earnings while you were the primary caregiver of a child under 7 born after December 31, 1958.

I never got the Canada Child Benefit because our income was too high. Can I still apply?

Yes. The form says that if you did not receive the Canada Child Benefit only because your family income was too high, you are considered to have been eligible.

Can both parents get the provision for the same child?

No. Only one person can be the primary caregiver at any time, so the provision applies to one account for the same period and child. If your spouse or partner received the Family Allowance but you were the caregiver, they can waive their rights in section D1.

Can I apply online instead?

Yes. Canada.ca says you can request the provision through My Service Canada Account or by mailing form ISP-1640. The fillable PDF can be saved but not submitted electronically.

Can I request it for a parent who has died?

Yes. For a CPP death or survivor benefit, the estate or the person handling the deceased's affairs completes the form, puts the deceased's SIN and name in Section A, and adds their own details in Section E.

Can I fill out ISP-1640 online with FileIt?

Yes. FileIt prints your answers, including names with accents, into Service Canada's official PDF and saves it in your vault. You sign it in pen and send it yourself.
