IRS red flags that trigger audits primarily involve mismatched income, excessive deductions/losses compared to income, claiming large business expenses (like a big home office deduction), and failing to report income from third-party sources (like 1099s).

To afford a $400k mortgage, you generally need an annual income between $100,000 and $125,000, but this varies greatly based on your down payment, credit score, interest rate, property taxes, and other debts, with some lenders suggesting around $90k-$110k if you have a large down payment and low debt, while others might require over $130k with less savings and higher rates. A common guideline is keeping your total monthly housing costs (PITI) under 28% of your gross income and total debt under 36% (28/36 Rule).
How many years back can the IRS come after you?
The IRS generally has 10 years from the tax assessment date to collect back taxes, known as the Collection Statute Expiration Date (CSED).
