Reasoning
**Clarifying deductions and calculations** I need to clarify if the deduction I'm working with exceeds the cap. R4 states it must not exceed the selected deduction cap or gross minus contribution. It seems there might be an issue with input formatting. Based on the rules, any malformed input is rejected, but I must obey the applicable deduction cap. For my calculation: gross is 9174.15, and after working through the deductions, my final net comes to 7222.52. I need the exact JSON fields to proceed.

Reasoning
**Calculating net contributions** I need to calculate the difference, starting with 353.50 against a cap of 400, and then look at my gross contribution of 9174.15 for July. The rate is .04 with a cap at 4000, leading to a contribution of 160.00. After deductions, my taxable total is 8660.65. The tax-free portion is 900, and I find the middle to upper boundary at 2800, giving me some more figures to work with for totals and net amounts.

Reasoning
**Calculating deductions and tax** I need to calculate deductions, and the current deduction of 353.50 exceeds the selected cap of 400—just checking if that's right. For the second row, the contribution rate is .04, with a cap of 4000, resulting in 160.00. The taxable amount comes to 8660.65 after deductions. The tax segments result in a total tax of 1438.13, leaving me with a net of 7222.52. I also need to check clauses, particularly R4 related to limits.
