<human>: Hi All,

So I'm currently salaried at $40k, but only half of that is reported for tax purposes. I receive two paychecks each month, both from the company. Basically $1,667 (half of my monthly salary) on one check, and the other check is whatever is left over without taxes. I can't remember the exact number but its around $1,300. In this case, how would I file tax returns? What about financing for large purposes? My mom, sister, and I are planning to buy a large house together next spring. My mom makes about $30k a year and my sister is working a part-time retail job while still in college, so I'm not sure how much she makes per year. What do I say when I go in for financing? If I decide to get my taxes done by a CPA, what do I tell them? Is this tax evasion on my part? On the company's part?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Only half my salary is taxed. What does this mean for me in terms of reporting taxes and financing on large purchases?
