Lesotho's tax year runs 1 April to 31 March. This skill covers 2026-27, from 1 April 2026.
Chargeable income is gross income less allowed deductions. Only 50% of otherwise allowable entertainment or meals expenses is deductible (s.35). Company losses carry forward. Losses from concessional manufacturing income carry forward only against later manufacturing income (s.47(3),(4)). Gains on assets go into chargeable income. Transfer pricing: between associates the Commissioner General may reallocate income, deductions and credits, and adjust intangible income (s.113). No separate documentation rule was found in the sections read.
The additional tax rate for late filing and late payment is 22% per twelve-month period as stated by RSL. It also applies to under-estimation and tax not withheld (Income Tax Act Part on additional tax, s.192 onward), where the specified rate is the rate RSL publishes. Poor records: additional tax equal to double the tax involved, as the Act words it.
RSL lists agreements with South Africa, the United Kingdom, Mauritius, Botswana and Eswatini, and information exchange agreements with Guernsey and the Isle of Man. The RSL ruling gives treaty rates of 5%, 10% and 12.5% for dividends, 15% for interest, and 7.5% or 10% for management fees and royalties; the rate depends on the treaty, so open the treaty before applying one.
Example 1: company with M1,000,000 of ordinary income pays 25%, M250,000.
name: Ordinary company M1,000,000
inputs:
profit: 1000000
steps:
- tax: profit * 0.25
expected:

Example 2, a decision: does M1,000,000 of qualifying manufacturing income beat ordinary income? Yes: 10% is M100,000, a saving of M150,000, and a dividend from it carries no non-resident withholding.
name: Manufacturing saving
inputs:
profit: 1000000
steps:
- mfg: profit * 0.10
- std: profit * 0.25
- saving: std - mfg
