Most penalties we see during IRD assessments do not come from underpaying income tax. They come from TDS. A business pays rent, a consultant, or a contractor, forgets to withhold tax at source, and then discovers two years later that the IRD has disallowed the entire expense and added it back to taxable income. For accountants running TDS software in Nepal manually through spreadsheets, the exposure is rarely visible until an assessment surfaces it.
Tax deducted at source is not a minor administrative step. It is a legal obligation placed on the payer under the Income Tax Act 2058. The withholding agent - your company - is liable for the tax whether or not it was actually deducted from the vendor. Get the rate wrong, miss the deposit deadline, or fail to issue a certificate, and the cost lands on the business, not the payee.
This piece walks through how TDS applies in Nepal by payment category, when and how to deduct it correctly, the deposit timeline and the penalty for missing it, certificate issuance, and the annual return obligation. The aim is a working reference an accountant can act on.
TDS Applicability in Nepal - Which Payments and at What Rate
The first question on any payment is whether it carries a withholding obligation, and at what rate. The Income Tax Act 2058 sets the framework: Section 87 governs withholding on employment income, Section 88 covers most non-employment payments such as rent, service fees, interest, royalty and commission, and Section 89 deals with payments under contracts. The rate depends on the nature of the payment, not the size of the vendor.
The categories that account for the bulk of routine deductions are house rent, service and management fees, professional and consultancy fees, contractor and supply payments, interest, dividend, and employee salary. Each sits under a different heading with its own rate. The common error in our experience is applying one blanket rate across all vendor payments because that is what the spreadsheet template was set up to do.
Use the table below as a working reference. Rates in Nepal are revised periodically through the annual Finance Act and IRD circulars, so treat these as indicative and confirm the current heading rate with the IRD or your tax advisor before applying it to a live payment.
| Payment Type | Indicative TDS Rate | Governing Provision |
|---|---|---|
| House rent (to a person) | 10% | Section 88 |
| Service fee / management fee | 1.5% | Section 88 |
| Professional / consultancy fee | 15% | Section 88 |
| Contract / supply payment | 1.5% | Section 89 |
| Interest payment | 15% | Section 88 |
| Dividend distribution | 5% | Section 88 |
| Employee salary | Applicable slab rate | Section 87 |
TDS rate is driven by the nature of the payment and its IRD heading, not by vendor size. Applying one default rate to every payment is the single most common cause of assessment adjustments.
Deducting TDS at Source - How and When to Do It Correctly
The obligation to withhold arises at the point of payment or at the point the amount is credited to the payee, whichever comes first. This timing trips up businesses that book an expense on accrual in one month and pay it in the next. If the credit is recorded in Ashwin and paid in Kartik, the deduction obligation generally attaches at the earlier event, and the deposit clock starts from there.
Deduct on the gross amount before the payment leaves the company, not as an afterthought once the vendor has already been paid in full. We have seen this repeatedly with clients: a contractor is paid the full invoice value, and the accountant then tries to recover the TDS portion afterwards. The IRD does not accept that the obligation was satisfied; the withholding agent remains liable for the amount that should have been deducted.
Under the Income Tax Act 2058, failure to deduct TDS can result in the related expense being disallowed during an IRD assessment and added back to taxable income, while the withholding agent remains liable for the tax that should have been withheld plus interest. Confirm current penalty and interest rates with the IRD as they are subject to Finance Act revision.
Maintain the TDS register heading by heading, with the IRD heading code recorded against each deduction. When the deposit is prepared, the figures must reconcile to the ledger and to the per-heading summary the IRD expects. A register that only records a total deducted, without the heading breakdown, will not survive scrutiny and slows every reconciliation at year end.
Withhold at the earlier of payment or credit, on the gross amount, and record each deduction against its IRD heading code. Recovering TDS after paying the vendor in full does not discharge the obligation.
Deposit Timeline and the Penalty for Missing It
Deducting correctly is only half the obligation. The amount withheld must be deposited with the IRD within the prescribed window. For most categories the deposit is due by the 25th of the month following the month of deduction. A deduction made in Mangsir is therefore deposited by the 25th of Poush, against the correct revenue heading and the company PAN.
Late deposit attracts interest and fees, and a pattern of late deposits is a flag the IRD notices. The risk is not only the direct charge. When deposits are chronically late, the underlying TDS records are usually disorganised too, and that is what turns a routine review into a detailed assessment.
TDS deducted in any Nepali month must reach the IRD by the 25th of the following month for most categories. Missing this date triggers interest and fees on the unpaid amount, and the withholding agent stays liable even if the tax was never deducted from the payee. Verify the exact interest and penalty rates with the IRD, as these are revised through the annual Finance Act.
Keep the bank deposit voucher or e-payment confirmation attached to the period's TDS summary. During an assessment the IRD officer reconciles the per-heading register to the actual deposit evidence, and a missing confirmation for even one month forces a wider lookback.
Build the deposit as a fixed monthly close task tied to a date, not a reaction to a reminder. The businesses that never incur TDS interest are the ones that treat the 25th as a hard internal deadline, with the register frozen and reconciled days before the cash actually moves.
The deposit deadline is the 25th of the following month for most headings. Late deposits cost interest and fees and signal disorganised records, which is exactly what escalates a review into an assessment.
Certificates and Annual TDS Return Filing
After depositing, two reporting obligations remain. First, the company must issue a TDS certificate to each payee - vendors and employees - showing the amount paid, the tax withheld, and the heading. Vendors need these certificates to claim the withheld amount against their own tax liability, and a vendor chasing a missing certificate at year end is a recurring friction point in owner-managed businesses.
Second, the withholding agent files periodic TDS returns with the IRD reporting the deductions made, the headings, and the deposits. These returns must reconcile to the deposits already made and to the certificates issued. When the three do not tie out - register, deposits, certificates - the difference is what an IRD officer pulls on first.
The structural problem with a manual process is that each of these three artefacts is produced separately, often by different people, from different spreadsheets. Reconciliation becomes a year-end scramble instead of a by-product of the monthly close. Treat the register as the single source, and certificates and returns should fall out of it without re-keying.
Certificates, deposits, and the periodic return must reconcile to one another. When all three derive from a single heading-wise register, reconciliation stops being a year-end risk.
Frequently Asked Questions
The withholding agent - the company making the payment - remains liable for the tax that should have been withheld, even though it was never deducted from the payee. The related expense can also be disallowed during an IRD assessment and added back to taxable income. The obligation does not transfer to the vendor.
For most categories the amount deducted in a Nepali month must be deposited with the IRD by the 25th of the following month, against the correct revenue heading and the company PAN. Late deposit attracts interest and fees. Confirm current rates with the IRD as they are revised through the annual Finance Act.
No. The rate is determined by the nature of the payment and its IRD heading - rent, service fee, professional fee, contract payment, interest, dividend or salary - not by the vendor's size. Applying one default rate across all payments is a common cause of assessment adjustments.
TDS That Reconciles Itself, Heading by Heading
MISAC carries the TDS structure as a native part of the platform, not a bolt-on. It maintains a TDS per-heading register with IRD heading codes in both Nepali and English, so each deduction is recorded against the correct heading at the point of entry. Dates are stored in both Bikram Sambat and AD, which keeps the deposit-by-the-25th calculation tied to the Nepali month the deduction actually fell in.
Because MISAC is accounting-first, the TDS on a payment voucher posts a complete double-entry journal in the same save. The withholding entry, the payable to the IRD, and the heading-wise register all move together, so the monthly deposit summary, the vendor certificates, and the periodic return are produced from one source instead of three unmatched spreadsheets. The reconciliation an IRD officer asks for is already done.
For accountants who have spent year ends untangling TDS registers by hand, this is the difference between compliance as a monthly by-product and compliance as a recurring risk. MISAC Intelligence Pvt. Ltd. builds this from the working experience of practitioners who have sat through Nepali tax assessments.
