Critical regulatory changes across 8 jurisdictions — verified against official government sources. Each change includes an expert Compliance Advisory action plan so your team knows exactly what to do.
Union Budget 2025-26 completely restructured the New Tax Regime slabs. The Section 87A rebate has been raised from ₹12,500 to ₹60,000, making taxable income up to ₹12,00,000 effectively zero-tax. Combined with the Standard Deduction of ₹75,000 available under the New Regime, an employee with gross salary up to ₹12,75,000 pays zero income tax.
Crucially, the New Regime is now the default regime. Employees who wish to continue with the Old Regime must explicitly inform their employer in writing at the beginning of the financial year. If no declaration is made, TDS will be computed under the New Regime.
New Regime Slabs (FY 2025-26): ₹0–4L: 0% · ₹4–8L: 5% · ₹8–12L: 10% · ₹12–16L: 15% · ₹16–20L: 20% · ₹20–24L: 25% · Above ₹24L: 30%
Step 1: Send a declaration form to all employees by April 30 each year asking them to choose their regime. Step 2: Update payroll software to default to New Regime. Step 3: Advise employees earning between ₹10L–₹15L to compare both regimes — the Old Regime may still be better if they have HRA + 80C + NPS deductions exceeding ₹3.5L. Step 4: Recompute TDS for April and May if declarations were delayed.
This is the most significant employer cost increase in the UK in a generation. From April 6, 2025, Employer NIC rises from 13.8% to 15% — an increase of 1.2 percentage points. Simultaneously, the Secondary Threshold (the salary above which employers start paying NIC) was cut from £9,100/year to £5,000/year.
The double impact: employers pay a higher rate on a larger portion of every employee's salary. For a £35,000 salary, employer NIC increases from approximately £3,571 to £4,500 — an extra £929 per employee per year. For a team of 50 employees at this salary level, that's £46,450 additional annual cost.
The Employment Allowance has been raised from £5,000 to £10,500 to partially offset this for smaller employers. This allowance reduces the employer NIC bill — eligible employers should ensure they claim it in their payroll software.
Model the full cost impact immediately if you haven't already. For a 100-person UK workforce averaging £45,000, the increased employer NIC adds approximately £150,000–£180,000 annually. This must be reflected in FY2025-26 budgets. Consider: (1) Employment Allowance eligibility check, (2) salary sacrifice schemes (pension, cycle-to-work) reduce NIable earnings for both employer and employee, (3) contractor vs. employee cost comparison now shifts.
Australia's Superannuation Guarantee (SG) rate has reached its legislated final rate of 12% from July 1, 2025, up from 11.5% in FY 2024-25. This is the completion of the long-running SG escalation schedule that began at 9.5%.
What this means: For an employee earning A$80,000/year, the employer super contribution increases from A$9,200 (11.5%) to A$9,600 (12%) — an increase of A$400/year per employee. Super must be paid quarterly into the employee's nominated complying fund. The Q4 FY2025-26 payment (April–June 2026) is due by July 28, 2026.
Concessional contribution cap for FY 2025-26: A$30,000/year (includes employer SG + employee salary sacrifice). Employees who use carry-forward rules from previous years can contribute above this cap.
The SG rate is calculated on Ordinary Time Earnings (OTE), not total remuneration. Overtime, annual leave loading, and certain allowances may not be OTE — confirm with your payroll system. Missed or late super payments attract the Superannuation Guarantee Charge (SGC) of up to 31.5% on underpaid amounts. This is not tax-deductible. Late payment is effectively a non-deductible penalty — always pay on time.
The Social Security (OASDI) taxable wage base for 2025 is $176,100, up from $168,600 in 2024 — an increase of $7,500. Employees and employers each contribute 6.2% on wages up to this threshold. Employees earning above $176,100 stop paying Social Security tax for the year at that point.
401(k) changes: The employee deferral limit for 2025 is $23,500. Under SECURE 2.0, employees aged 60–63 have an enhanced catch-up limit of $11,250 (vs. the standard $7,500 for 50+). This super catch-up applies for the first time in 2025.
IRA limits: Traditional and Roth IRA contribution limit stays at $7,000 ($8,000 for 50+). Roth IRA income phase-out: $150,000–$165,000 (single), $236,000–$246,000 (MFJ).
For employees earning above $168,600, both employer and employee will continue paying SS tax until they hit the new $176,100 ceiling. This adds up to $465.20 in additional SS tax per employee (employer cost: additional $465.20 in employer FICA). State payroll tax rates are separate — California SDI at 1.2% with no wage cap is notable for high-earning California employees.
From January 1, 2025, the CPF Ordinary Wage (OW) ceiling increased from S$6,800 to S$7,400 per month, as part of the phased enhancement roadmap to improve retirement adequacy. This is the second of three planned increases (the ceiling was S$6,000 before Sept 2023).
Impact: For employees earning S$7,400/month or above, the maximum employee CPF contribution is now S$1,480/month (20%) and employer contribution is S$1,258/month (17%) for employees aged 55 and below. This represents S$81,120 in additional annual CPF contributions for the highest earners compared to the S$6,000 ceiling.
The Annual Wage Supplement (AWS or 13th month bonus) and variable bonuses are Additional Wage (AW) — subject to a separate CPF cap. The AW ceiling for CPF contributions = $102,000 minus total OW for the year. If an employee earns S$7,400/month × 12 = S$88,800 OW, then AW cap = S$102,000 − S$88,800 = S$13,200. Bonuses above S$13,200 do not attract CPF.
Three significant changes for Canadian payroll in 2025. CPP2 (second-tier Canada Pension Plan): employees earning between C$73,200 and C$81,900 now pay an additional 4% CPP contribution on that band. CPP1 maximum pensionable earnings are C$71,300 at 5.95% (with C$3,500 exemption).
EI Rate reduction: The Employment Insurance premium rate for employees decreased to 1.64% (from 1.66% in 2024) on insurable earnings up to C$65,700. Employer rate is 1.4× employee rate = 2.296%.
Federal Minimum Wage: Raised to C$17.75/hour from April 1, 2025. This applies to federally regulated industries (banking, airlines, telecom). Provincial minimums are often higher and take precedence where applicable.
CPP2 contributions are reported in Box 16A on the T4 slip — separate from CPP1 in Box 16. Ensure your payroll system generates both boxes correctly. CPP2 is fully deductible as a tax credit (15% federal). Employees reaching the CPP2 ceiling stop contributing to CPP2 for the rest of the year — system must track this threshold correctly.
Three critical India income tax milestones in June–July 2026 require employer action. Form 16 issuance: Employers must issue Form 16 (Part A + Part B) to all employees for FY 2025-26 by June 15, 2026. Form 16 is generated from the TDS certificate downloaded from TRACES portal.
Advance Tax Q1 — FY 2026-27: The first installment of Advance Tax (15% of estimated annual liability) is due June 15, 2026. Applicable for individuals with income from business, capital gains, house property, or other sources where employer TDS is insufficient. Salary-only employees are generally covered by employer TDS.
ITR Filing — AY 2026-27: Non-audit individuals and HUF must file their Income Tax Return for FY 2025-26 by July 31, 2026. E-verify within 30 days of filing. New regime filers cannot carry forward losses except business losses.
Employers: (1) Download Form 16 Part A from TRACES by June 1 — don't wait until the last day. Part B (salary breakup) must be prepared internally. (2) Employees who switched regimes mid-year may have mismatched TDS — reconcile before issuing Form 16. (3) Advise employees with freelance income, house property, or capital gains to check if their Advance Tax deposit is required by June 15.
UAE Corporate Tax at 9% on net taxable income above AED 375,000 is now in its second full financial year for most businesses. The tax return is due 9 months after the end of the taxable period. For companies with a December 31, 2025 year-end, the CT return is due September 30, 2026.
Small Business Relief is available for businesses with revenue ≤ AED 3,000,000 — they can elect to be treated as having no taxable income. This election must be made when filing the CT return. Qualifying Free Zone Persons may benefit from 0% CT if conditions are met (ring-fencing rules apply).
The UAE CT law includes transfer pricing provisions aligned with OECD guidelines. Related party transactions must be at arm's length. Maintain a Master File and Local File if group revenue exceeds AED 3.15 billion (globally). Failure to maintain documentation attracts penalties of AED 100,000–500,000. Start documentation now if not already in place.
