Yes, you can apply even if you’ve been self-employed for only a short time, but you're going to find it difficult to prove a sustained self-employment income. If your self-employment is a side gig and you're still employed elsewhere, you should be okay. Otherwise, you may want to consider an alternative payment or financing option – debit cards, prepaid cards, bank loans and BNPL – until you can prove at least two years of self-employment income.
