TDS Interest and Penalty Impact Calculator

A single TDS default — short deduction, non-deduction, delayed deposit, delayed return filing, or wrong section code — can cascade into four distinct statutory layers that stack on top of each other and are each recoverable independently by the tax administration. Layer one is Section 201(1A) of the Income-tax Act — mandatory interest at 1 percent per month or part of a month from the date on which the tax was deductible until the date it is actually deducted (for short-deduction or non-deduction), and 1.5 percent per month or part of a month from the date the tax was deducted until the date it is actually paid to the Central Government (for delayed deposit). This is compensatory interest, not a penalty, and is not discretionary. Layer two is Section 234E — a late-filing fee of Rs 200 per day of delay in filing the quarterly TDS return (Form 26Q for non-salary residents, Form 27Q for non-residents, Form 24Q for salary, Form 27EQ for TCS), subject to a cap equal to the TDS quantum for the statement. Section 234E was upheld as constitutional by the Bombay High Court in Rashmikant Kundalia v. Union of India (2015). Layer three is Section 40(a)(ia) of the Income-tax Act — 30 percent of the expenditure on which TDS was deductible but not deducted or, if deducted, not deposited by the due date under Section 139(1) for filing the return of income, is disallowed as a deduction in computing the taxable business income. The effective corporate-tax cost is 30 percent of 30 percent of the grossed-up expenditure at the 30 percent regular corporate rate (or 30 percent of 22 percent at the Section 115BAA concessional rate). Layer four is Section 276B — prosecution for wilful failure to pay TDS after deduction, imprisonment of three months to seven years with fine. This is a criminal provision that is invoked by the Commissioner (TDS) with sanction of the Principal Chief Commissioner or Chief Commissioner, and is not extinguished by subsequent deposit of the TDS. The four layers stack — a company that fails to deduct TDS on a large expenditure faces Section 201(1A) interest, Section 234E fee, Section 40(a)(ia) disallowance and, in extreme cases with wilfulness inference, Section 276B prosecution — all in respect of the same underlying default. This calculator quantifies the three monetary layers and flags the fourth.

Section 201(1A) of the Income-tax Act prescribes two distinct interest rates. For short-deduction or non-deduction cases — where the deductor failed to deduct TDS or deducted it at a rate lower than the statutory rate — the rate is 1 percent per month or part of a month, running from the date on which the tax was deductible until the date it is actually deducted. For delayed-deposit cases — where the deductor correctly deducted TDS but failed to deposit it to the Central Government within the prescribed time — the rate is 1.5 percent per month or part of a month, running from the date on which the tax was deducted until the date it is actually paid. The 'month or part of a month' rule is critical for cash-flow modelling. If TDS is deducted on 5 April but paid on 8 May (34 days late), the interest is calculated for two months (part of April + part of May) at 1.5 percent per month, not for 34 days on a prorated basis. If deducted on 5 April but paid on 7 April (2 days late), the interest is still 1.5 percent for one month. The Central Board of Direct Taxes (CBDT) has held in multiple circulars that the interest is compensatory and mandatory — there is no discretion with the assessing officer to waive or reduce it. Section 220(2A) provides limited scope for waiver but only in exceptional cases (genuine hardship, bona fide reasons, cooperation with tax authorities) and only for interest under Section 220(2), not for Section 201(1A). This tool computes 201(1A) interest per the correct 'month or part of a month' rounding, and shows both the days count and the months count so the finance manager can see the cliff-edge cost of a one-day slip across a month boundary.

Section 40(a)(ia) of the Income-tax Act, as amended by the Finance Act 2014 with effect from Assessment Year 2015-16, disallows 30 percent of any sum payable to a resident on which tax was deductible at source under Chapter XVII-B but on which the tax has either not been deducted or, after deduction, has not been paid on or before the due date specified in Section 139(1) for filing the return of income. The 30 percent portion of the expenditure is added back to the assessee's taxable business income. Two important consequences follow. First, the disallowance is not permanent — the amount disallowed in the year of default can be claimed as a deduction in the subsequent year in which the TDS is finally deducted and deposited (or paid to the government under the Section 201 recovery mechanism). Second, the effective cash cost depends on the applicable corporate-tax rate. At the regular corporate rate of 30 percent (for companies not opting into Section 115BAA), the effective cost is 30 percent of 30 percent = 9 percent of the grossed-up expenditure on which TDS was deductible. At the Section 115BAA concessional rate of 22 percent (for domestic companies foregoing specified deductions and incentives), the effective cost is 30 percent of 22 percent = 6.6 percent. At the Section 115BAB concessional rate of 15 percent (for new manufacturing companies), the effective cost is 30 percent of 15 percent = 4.5 percent. For a small company at 25 percent (turnover up to Rs 400 crore), the effective cost is 30 percent of 25 percent = 7.5 percent. The disallowance is triggered by non-deduction and by non-deposit past the Section 139(1) due date — it is NOT triggered by delayed deposit within the year if the deposit happens before the 139(1) due date. Short-deduction under Section 40(a)(ia) has historically been contested — the CBDT's view in Circular 275/29/2014 and the Karnataka High Court in CIT v. Prakash Iron Store (ITA 337 of 2015) treat short-deduction as outside the 40(a)(ia) net, but the assessee should verify the current jurisdictional position with counsel. This calculator applies the disallowance to non-deduction cases and flags the short-deduction position for consultation.

Section 276B of the Income-tax Act provides that if a person fails to pay to the credit of the Central Government the tax deducted at source by him as required by Chapter XVII-B or the tax payable by him as required under the second proviso to sub-section (1) of Section 194B, he shall be punishable with rigorous imprisonment for a term which shall not be less than three months but which may extend to seven years, together with fine. The essential ingredients for Section 276B prosecution are three. First, TDS must have been actually deducted from the deductee's payment — Section 276B does not apply to non-deduction cases (which are covered by the recovery machinery of Section 201 and the disallowance under 40(a)(ia)). Second, the deductor must have failed to pay the deducted TDS to the Central Government within the prescribed time. Third, the failure must be wilful — mens rea is a constitutional requirement for criminal offences and has been upheld by the Supreme Court in Madhumilan Syntex Ltd v. Union of India (2007) 290 ITR 199, which held that Section 278AA provides a defence where the assessee proves that the failure was due to reasonable cause. In practice, prosecution is initiated by the Commissioner (TDS) with sanction under Section 279 of the Principal Chief Commissioner or Chief Commissioner (in the case of a body corporate, the directors/principal officers are impleaded under Section 278B). The CBDT's Instruction No. 5051 of 1991 and subsequent guidelines direct that prosecution should be initiated in cases involving TDS default of Rs 25 lakh or more or where the default period exceeds one year, and where the assessing officer records satisfaction of wilfulness. Prosecution can be compounded under Section 279(2) on payment of the compounding fee prescribed by CBDT (typically 3 percent of the TDS defaulted, subject to minimum thresholds), but compounding is a matter of discretion and is generally not granted if the assessee is a repeat offender or if the default is egregious. Recent enforcement trend: the CBDT's 2018-2019 push on TDS prosecution saw ~2,000 cases initiated per year, with the Directorate of TDS focusing on non-deposit of large TDS deductions by contractors, real-estate developers, and financial-services firms. This tool flags Section 276B exposure when the default type is 'delayed deposit' and the delay period exceeds a threshold — the finance manager must consult tax counsel on the fact-specific likelihood of prosecution.

Section 234E of the Income-tax Act is a fee, not a penalty — this legal characterisation is important. The Bombay High Court in Rashmikant Kundalia v. Union of India (2015) 373 ITR 268 upheld the constitutional validity of Section 234E and characterised it as a compensatory fee for the administrative burden imposed on the tax administration by delayed TDS statements. As a fee, Section 234E is not subject to the waiver mechanisms that apply to penalties under Section 273A or 273B. The fee is Rs 200 per day of delay in filing the quarterly TDS statement (Form 26Q, 27Q, 24Q, or 27EQ), subject to a cap equal to the amount of TDS/TCS liable to be paid or collected for the quarter. The cap is a hard ceiling — the fee cannot exceed the TDS quantum. Payment of the Section 234E fee must be made before filing the TDS statement (via Challan 281 with the appropriate section code), otherwise the statement will be rejected by the TIN-FC. Section 234E interacts with Section 271H, which is a separate penalty provision for failure to furnish TDS/TCS statements or for furnishing incorrect information. Section 271H penalty ranges from Rs 10,000 to Rs 1,00,000 and is imposable by the assessing officer at his discretion. However, Section 271H(3) provides an exception — no penalty under 271H shall be imposed if the TDS statement is furnished within one year from the due date, provided the Section 234E fee has been paid and the TDS along with interest has been deposited. This 'one-year window' is the practical safety valve — a delayed TDS statement filed within one year of the due date, with the 234E fee paid and the TDS + 201(1A) interest deposited, attracts only the 234E fee and not the 271H penalty. Beyond one year, both 234E fee (capped at TDS quantum) and 271H penalty (Rs 10,000 to Rs 1,00,000) are levied. This calculator quantifies Section 234E only — Section 271H is discretionary and is flagged as a separate exposure requiring assessing-officer engagement. Illustrative — actual quantum depends on assessing officer discretion, jurisdictional practice, and Section 273A remission possibilities.
