# Common Conditions Across the Presumptive Sections
These clarifications apply across Sections 44AD, 44ADA and 44AE.
## Deductions deemed allowed
- All deductions u/s 30 to 38 (including depreciation) are deemed to have already been allowed. No further claim is possible.
- No set-off of current or unabsorbed depreciation separately.
- However, business losses u/s 72, 73 and 73A can be set off against presumptive income.
## Depreciation and WDV
- The closing WDV of the block of assets is deemed to have been adjusted by notional depreciation — i.e. the WDV is reduced as if depreciation had actually been claimed during the presumptive years. This matters when the assessee later exits the scheme and computes actual depreciation/capital gains.
## Partner's interest and remuneration
| Section | Interest/remuneration to partners |
|---|---|
| 44AD | Not deductible |
| 44ADA | Not deductible |
| 44AE | Allowed, subject to limits in Section 40(b) |
## Books and audit
- If income is declared on a presumptive basis, no books need be maintained and tax audit does not apply.
- Under 44ADA and 44AE, if a lower income than presumptive is declared, books and audit become mandatory where total income exceeds the basic exemption limit.
## Payment of advance tax
| Section | Advance tax |
|---|---|
| 44AD & 44ADA | Single instalment — 100% by 15th March of the financial year |
