I reckon a Stocks and Shares ISA is an excellent investment vehicle to help build wealth. If you’re a regular reader, you might know it’s a bit of a Foolish favourite!

Let me explain why I’m a fan, and describe one stock I’d love to buy to help me make the most of my ISA.

Why this ISA?

There are a few reasons why this particular type of ISA is attractive to me. When it comes to building wealth, dividends are a great way to help me do this.

If I buy shares within the ISA, any dividends I receive aren’t liable for tax, meaning I get to keep them, helping me build a pot of money faster. I could even let them compound for a number of years to get that pot really growing.

Please note that tax treatment depends on the individual circumstances of each client and may be subject to change in future. The content in this article is provided for information purposes only.

Readers are responsible for carrying out their own due diligence and for obtaining professional advice before making any investment decisions.

The other aspect of the ISA which is attractive is the generous allowance I’m able to invest. Over a year, I can invest up to £20,000. I may not have £20k every year, but if I have disposable funds to invest, I could go up to that amount. This gives me great flexibility to really put my money to work to help me build wealth for the future.

Infrastructure building

When I have some funds to invest, I’d buy BBGI Infrastructure (LSE: BBGI) shares for my own ISA.

As the name alludes to, BBGI is an investment company listed on the FTSE 250 that invests in infrastructure projects around the world. It covers territories such as Europe, North America, and Australia. The type of infrastructure includes essential services such as roads, hospitals, and schools.

The shares have meandered up and down in the past 12 months, which is a result of higher interest rates, inflation, and overall economic turbulence. They’re pretty much where they started, from 133p at this time last year, to 132p at present.

This leads me nicely to my bearish view of the business, and issues that could dent earnings and returns. Unfortunately, economic issues and higher interest rates and inflation can lead to a cut in spending, especially on large infrastructure projects. BBGI could find earrings and returns dented by the current malaise we find ourselves in.

Moving to the other side of the coin, BBGI possesses defensive attributes, in my view. This is due to the essential nature of the projects it invests in, plus the fact they’re government-backed. This can add a layer of security to the project overall.

From a fundamental view, a dividend yield of 6.2% is extremely attractive. For context, the FTSE 100 average is 3.6%. However, I do understand that dividends are never guaranteed. Furthermore, the shares are currently trading at a 10% discount to its current net asset value, which is another feather in my investment case’s cap.

Overall, BBGI has a good presence, solid fundamentals, and potentially lucrative business model for years to come. This could help the dividends flowing, and helping me boost my ISA and build wealth.
