However, the instant tax write-off for businesses' expenses on items that cost less than $20,000 sure will. I imagine many small business owners have woken up this morning plotting business and personal expenses over the next year, with an eye on those expenses that fall into that grey area between the two.

We might see business owners decide to buy small cars, or equipment such as printers and computers for their business. They might also be inclined to invest in other expenses, such as accounting software to make their lives easier. But this is the part of the budget that's definitely open to rorting. It's all too easy for business owners to claim personal expenses as business expenses and the Australian Taxation Office doesn't have the firepower to clamp down on this.

I'm also sceptical about some of the other measures. Start-ups can now immediately claim expenses related to setting up a business, which should ostensibly encourage people to set up a new enterprise. Sure, that's a benefit to a start-up. But perhaps more thought could have gone into what could be done to encourage people who have a high chance of making a success of their enterprise to hang out a shingle, rather than taking this broad-brush approach.

Another initiative that will allow start-ups to raise money from mum and dad investors – known as equity crowd funding – is quite frankly worrying. Most of us don't have the skills to determine whether a start-up investment is a good idea and my fear is that mum and dad investors will sink their savings into ventures that have no chance of success, and thus lose their money.
