Thank you so much! This breakdown is super helpful. Quick follow-up though - for the actual amount of withholding, should I be using what was initially withheld ($78k) or the net amount after they already got that partial refund through the T2062 process?

You should use the net amount after the partial refund. So if $78k was initially withheld but $22k was already refunded based on the T2062 adjustment, you'd report $56k on line 43700 as the withholding tax amount. The CRA system should already have a record of both the initial withholding and the T2062 adjustment, but I always recommend including a brief note with the return explaining these amounts to avoid any confusion during processing.

For non-residents, you don't need to file a separate provincial tax return. The federal T1-NR handles both federal and provincial taxation. Non-residents pay a flat 25% federal tax on taxable Canadian property, with no separate provincial component. Just make sure you're correctly identifying the property's location on the return since this affects CRA's internal processing, but you won't need to complete any provincial-specific forms for a non-resident property sale.

Thanks so much for this reassurance! I'm still a bit nervous about taking the deduction without photos. For the documentation you mentioned - would a detailed written description with measurements and a hand-drawn floor plan be sufficient? Or should I try to find other proof like emails sent from that workspace?

A detailed written description with measurements and a hand-drawn floor plan is absolutely sufficient documentation. Date it and keep it with your tax records. Including details about the built-in desk, the three walls forming the alcove, and how you used the space for specific business activities strengthens your case. Adding some supporting evidence like business emails, client invoices you created there, or phone records showing client calls would be helpful supplementary documentation, but not strictly necessary. The IRS understands that people move and may not have photographs of previous spaces. Your contemporaneous written records are considered valid documentation, especially when they're detailed and consistent with your business activities.

TurboTax Self-Employed version handles home office deductions pretty well. It walks you through all the questions and helps calculate both the regular and simplified methods. I've used it for the past 3 years with no problems. Just make sure you get the Self-Employed version, not the regular one.

Thanks so much for breaking down those method codes! That makes much more sense now. So if I understand correctly, my desk and MacBook were essentially "fully depreciated" for federal purposes in the first year because of the 100% bonus, but for California they're still on their regular depreciation schedules? When I enter these as existing assets in FreeTaxUSA, do I need to enter different prior depreciation amounts for federal vs state? Or does the software handle that difference automatically?

Yes, you've got it exactly right! For federal purposes, your desk and MacBook were fully depreciated in the first year thanks to 100% bonus depreciation available in 2022. But for California, they're following their normal depreciation schedules over 7 and 5 years respectively. FreeTaxUSA should handle the federal vs state difference automatically once you input the correct information. You'll want to enter the assets with their original acquisition dates, costs, and depreciation methods. For "prior depreciation," enter the cumulative federal depreciation taken to date (which would be the full amount for the desk and MacBook, and the partial amount for the iPhone). The software will then apply the correct state adjustments automatically. If you want to double-check the calculations, the state return should include a specific form showing the depreciation differences between federal and California.

This is super important! I messed up my taxes last year because I didn't realize the rates change throughout the depreciation period. Is there an easy calculator anywhere that shows what the percentage should be for each year?

3 Wait, is that really true even if you're claimed as a dependent? I thought dependents couldn't open retirement accounts.

9 Yes, it's absolutely true! Being claimed as a dependent doesn't affect your ability to contribute to a Roth IRA. The only requirements are that you have earned income and don't exceed the contribution limits (either your total earned income or $6,500 for 2023, whichever is lower). Many parents miss this opportunity for their working teens. It's a fantastic way to start building tax-free retirement savings early, and the compound interest over decades is incredible. I opened mine at Vanguard with help from my parents when I was still in high school.

11 Good point! Does anyone know if you need to file state taxes if you're under 18? I'm in California and making about $8,000 this year through my parent's Venmo.

I tried Wealthsimple Tax last year for my non-resident return. It works okay for simple situations, but I found it struggled with properly applying tax treaty benefits. I ended up switching to a professional preparer because I wasn't confident it was handling everything correctly.

Actually, if you have Canadian self-employment income, the deadline is June 15, even for non-residents! But any balance owing is still due by April 30 to avoid interest charges.

You're absolutely right about the June 15 extension for self-employment income. Thanks for that correction! Always good to remember that even with the extended filing deadline, paying after April 30 will result in interest charges, even if you're not charged a late-filing penalty.
