Well the cutoff is 150K for AGI, not MAGI. Assuming your AGI is 150,013, it would just start phasing out at 150K up to 160K. If it's just you and your spouse, the difference in the stimulus payment would be $4. If you also have 2 children it would be $7. Did you already get a payment or are you still waiting? You can check the status on IRS website.
