TDS done right, every salary. Section 192. Both regimes. Form 16 in one click.

Why TDS goes wrong in most schools

It is the 7th of June, the year-end TDS deadline has passed, and the principal forwards an email from a teacher: 'Sir, my Form 16 shows ₹84,000 deducted, but Form 26AS on the income tax portal shows only ₹62,000. Please correct.' The accountant opens his Excel file. The TDS he calculated was based on the old regime — but the teacher had elected the new regime in April, mentioned it on a sticky note in February, and the sticky note moved offices when the cabin was repainted. The school's Form 24Q for Q4 was filed using the old regime numbers. Now the teacher cannot file her own ITR. The accountant cannot reconcile. The principal cannot answer.

This is how TDS goes wrong in most Indian schools — not because the rules are too complex, but because the rules live in three different places: the income tax portal, the school's payroll Excel, and the accountant's memory. When any one of them drifts, the school discovers it months later — usually through a teacher's complaint or a TRACES default notice.

The cost is not the calculation error. The cost is the Section 271C penalty, the interest under Section 201(1A), the teacher's lost trust, the reconciliation that takes the next three weekends, and the audit query that arrives in October about the May Form 16. We built TDS the way it should be built — every rule, every regime, every section, in one place that updates every time anything changes.

How Inkwelly computes TDS, every salary

Section 192 of the Income Tax Act 1961 requires the employer to deduct income tax on salary every month, computed against projected annual income. The employer estimates the employee's annual salary, applies the exemptions and deductions she has declared, computes annual tax under her chosen regime, and divides by the remaining months of the FY. The amount deducted in any one month depends on what has already been deducted in past months, what investments the employee has declared, and which regime is currently selected.

Inkwelly does this every payroll run, every month, every employee. When the accountant runs the November payroll, Inkwelly opens each teacher's record — current month's gross, year-to-date earnings, declared regime, declared investments, HRA exemption inputs, home loan interest, education loan interest, donations — applies the FY 2025-26 slabs (or the slabs of whichever FY the period belongs to), computes the projected annual tax, subtracts what has already been deducted in April through October, and produces the November TDS line. The payslip explains the math. The audit log records the inputs.

If the teacher updates her investment declaration in January, the next run automatically recomputes — the new declared investment reduces projected tax, the remaining months' TDS adjusts accordingly. No 'please send me the latest declaration' email chain. No spreadsheet rerun. No drift between what the school deducts and what Form 26AS will eventually reflect.

TDS, end to end inside one module

“Pichhle saal Form 16 mein DA arrears ka calculation galat tha — har teacher ko refund file karna pada. Is saal Inkwelly ne Section 89(1) automatically apply kar diya, sab ka Form 16 first time mein hi correct.”

Five real situations Inkwelly handles automatically

1. Mid-year regime switch. A PGT teacher elects the new regime in April, then changes her mind in October after buying a ₹1.5 lakh ELSS through her broker. She updates her declaration on the employee portal and switches to the old regime. Inkwelly recomputes the remaining months' TDS using the old regime, the year-end Form 16 reflects the old regime, Form 24Q for Q3 onwards shows the revised numbers. No accountant intervention required.

2. Increment in August. A TGT teacher's salary increases from ₹38,000 to ₹44,000 from August. Inkwelly reprojects her annual income, applies the new slab if she crosses one, computes the increased TDS for the remaining months. The August payslip shows both the salary increase and the consequent TDS change, with a clear note explaining why.

3. DA arrears for six months. Cabinet revises DA retrospectively from January, payable in July. Inkwelly recomputes January through June salaries with the revised DA, aggregates the arrears, applies Section 89(1) relief if the teacher elects, and adds the arrears to the July payslip with the relief shown. Form 24Q for Q2 reflects the arrears and the relief.

4. HRA proof submission deadline. A teacher claimed ₹2.4 lakh HRA exemption in her April declaration. Come 25 January, she has not uploaded her rent agreement or rent receipts. Inkwelly auto-reminds her on 20 January, again on 28 January. By 31 January no proof — the HRA exemption is revoked for the year-end true-up, the March payslip recoups the additional TDS, and Form 16 reflects the corrected exemption.

5. Resignation on the 17th. A teacher resigns on the 17th of November. Inkwelly's F&F workflow computes pro-rata salary for 17 days, leave encashment, gratuity if eligible, notice pay or recovery, and runs a final TDS true-up — adjusting for partial-year income, applying the right standard deduction, computing the final tax. The Form 16 issued at year-end (or earlier on request) reflects the F&F.

Limits, safety and the small print

A few things every school accountant should know before going live with Inkwelly TDS.

Slab updates are version-controlled. When the Finance Act of any FY changes slabs, standard deduction, or surcharge thresholds, we publish the updated rules as a slab version effective from 1 April of that FY. Past pay periods continue using the slabs of their FY. There is no retroactive change unless the law itself is retroactive (rare).

Form 26AS reconciliation lives outside Inkwelly. Inkwelly produces Form 24Q and Form 16. Once the school files Form 24Q on TRACES, the deducted TDS appears in each employee's Form 26AS. We do not auto-reconcile against Form 26AS — that is something the employee herself checks before filing her ITR. We can flag mismatches if the school exports YTD figures and a CA cross-checks; we do not access TRACES directly on the school's behalf.

Section 87A rebate. Under both regimes, the rebate is applied automatically if the eligible employee's taxable income is within the threshold (₹5 lakh old / ₹7 lakh new). We do not over-apply: when income marginally crosses the threshold, the marginal-relief rule is applied per Finance Act 2023 amendments.

TDS on non-salary payments (Form 16A). Inkwelly handles TDS on rent paid above ₹2.4 lakh per year (Section 194I), contractor payments above the threshold (Section 194C), professional fees (Section 194J) — but only if these payments flow through the school's payroll module. For payments processed through Tally or another accounting tool, we provide an import flow at quarter-end so Form 16A can still be issued from Inkwelly.

Audit trail. Every TDS computation, every regime switch, every investment declaration update is timestamped, IP-logged, and tied to a user account. When a teacher disputes her Form 16 in October, the audit log answers 'who entered what, when' in seconds. When CBDT asks during an audit, the proof is on file.

TDS that ends every June 14th panic

Inkwelly turns Form 16 issue from a 3-week ordeal into a 30-second click. Section 192, both regimes, Form 24Q quarterly, Section 89(1) on arrears — all in one place that updates every payroll run.
