Complete this form to calculate your British Columbia clean buildings tax credit.
You can claim this refundable tax credit if you paid or incurred expenditures for qualifying retrofits, as certified by the British Columbia Ministry of Finance, to improve the energy efficiency of eligible commercial and residential buildings in British Columbia that have 4 or more units.
The BC clean buildings tax credit is 5% of your qualifying expenditures (excluding assistance) for the qualifying retrofit.
You must be a resident of British Columbia or have income allocated to British Columbia at the end of the year that you are claiming the credit for.
If you are a member of a partnership, calculate your appropriate portion of the partnership's tax credit using the information provided to you by your partnership.
Claim the credit on your return for the year following the tax year that the retrofit is completed. Claim your credit no later than 18 months after the end of the tax year that follows the tax year that the retrofit was completed in.
The retrofit must be completed before April 1, 2026, and be certified by the British Columbia Ministry of Finance to qualify.
The application for certification must be filed before April 1, 2027.
The amounts shown on your certificate for the retrofit from the British Columbia Ministry of Finance are estimates only.
See page 3 for information about qualifying and non-qualifying expenditures.
For expenses that were not incurred by a partnership, complete part 1 and part 2. For credit amounts you may be entitled to as a member of a partnership, complete part 3 and part 4 if the partnership provided you with the total qualifying expenses incurred by the partnership. If the partnership provided you with your allocated credit amount, do not complete part 3 and part 4. Instead, enter your credit amount directly on the last line of Part 4.
Use a separate Form T1356 for each qualifying retrofit you are claiming for the year. Enter the total of these on your Form BC479, British Columbia Credits
If you are filing a paper return, attach this form to your return. Do not include your receipts but keep them in case you are asked to provide them later.
