End of financial year (EOFY) is a great time for Australian small businesses to purchase or have a solar power system.  In May last year, then-Treasurer Joe Hockey announced a significant boost to the value of items that can be written off immediately instead of over several years – from $1,000 to $20,000. “Small business can claim an immediate tax deduction for each and every item they purchase up to $20,000 … anything under $20,000 is immediately 100 per cent tax deductible from tonight,” said Mr. Hockey.
