I simply get too small profit to reinvest and grow
My understanding is that only profit is taxible.
If you take your income and invest it in your business, than it is a business expense that lessens the profit.
How to make investments in your business and what to buy to lessen your tax burden was discussed here quite often. A search for tax would probably come up with some good ideas.
