Progressive Tax Made Simple
Our calculator uses a progressive tax system — the more you earn, the higher the rate only on the extra income. You never pay the top rate on your whole salary.
Step 1: Tax-Free Threshold
The first SBD 30,080 of your annual income is tax-free (as per current Solomon Islands IRD rules).
- •Income ≤ SBD 30,080 → 0 tax
- •Anything above → becomes your taxable income
SBD 30,080
No tax on the first portion
Step 2: The Tax Brackets (Used in This Calculator)
Bracket 1
11%
First SBD 15,000 of taxable income
Bracket 2
23%
Next SBD 15,000
Bracket 3
35%
Next SBD 30,000
Bracket 4
40%
Everything above
Note: These are the illustrative brackets implemented in the calculator. Official Solomon Islands PAYE is progressive above the SBD 30,080 threshold — confirm current details with ird.gov.sb.
Example: SBD 70,000 Annual Income
Tax Breakdown:
- SBD 15,000 @ 11% = SBD 1,650
- SBD 15,000 @ 23% = SBD 3,450
- SBD 9,920 @ 35% = SBD 3,472
Total Tax ≈ SBD 8,572
Net Take-Home ≈ SBD 61,428
