Armed Forces Reservist Pay and Tax UK 2026/27
Reservist training pay and mobilisation pay are both taxable, but a reservist's civilian employer receives compensation for their absence, and specific NI rules apply during mobilisation. Here is how reservist pay and tax work in 2026/27.
Two types of reservist pay, both taxable
Armed Forces reservists can receive pay in two main contexts: training pay (for the annual training commitment most reservists undertake, commonly around 27 days a year plus additional training) and mobilisation pay (received if called up for full-time regular service, such as an operational deployment). Both are taxable employment income, assessed using the same Personal Allowance and income tax bands as any other UK earnings.

Priya works full-time in a civilian job earning £34,000 and also serves as an Army Reservist, receiving £2,200 in training pay across the year for her annual training commitment.
| Income source | Amount | Tax treatment |
|---|---|---|
| Civilian salary | £34,000 | Taxed via employer's PAYE (main job) |
| Reservist training pay | £2,200 | Taxed via MOD payroll, likely at BR (basic rate, no allowance) since her civilian job already uses her Personal Allowance |
| Combined taxable income | £36,200 | Assessed for total tax due |
If both payers deduct tax correctly relative to Priya's overall position, no further tax is owed at year end; if not, any small discrepancy is typically resolved through HMRC's end-of-year reconciliation.
Worked example 2: mobilised reservist, employer tops up pay
Tom, a reservist, is mobilised for a 6-month operational deployment. His forces pay for the deployment is £16,000 for the period, and his civilian employer agrees to top up the difference between his forces pay and his usual civilian salary.
| Income source | Amount (6 months) | Tax treatment |
|---|---|---|
| MOD mobilisation pay | £16,000 | Taxed via MOD payroll |
| Employer top-up payment | £2,500 | Taxed via civilian employer's payroll |
| Combined taxable income (period) | £18,500 | Assessed across both payers |
Tom's civilian employer may separately claim compensation from the MOD for costs associated with covering Tom's absence — this is a business-to-MOD transaction and does not change Tom's own personal tax position.

Aisha's civilian employer does not continue any salary during her mobilisation, so her only income for the 4-month deployment period is her MOD mobilisation pay of £11,000.
| Income source | Amount (4 months) |
|---|---|
| MOD mobilisation pay | £11,000 |
| Civilian salary | £0 (not paid during mobilisation) |
Aisha's tax position for this period is based solely on her MOD pay, taxed via MOD payroll using her normal tax code, since she has no concurrent civilian income to complicate the allocation of her Personal Allowance during the mobilisation period.
Civilian employer compensation
Employers of mobilised reservists can apply to the Ministry of Defence for compensation covering certain costs incurred because of a reservist employee's absence — for example, recruitment or training costs for temporary cover. This scheme exists specifically to reduce any financial disincentive for employers to support staff members who are also reservists, and is entirely separate from, and does not affect, how the reservist's own personal pay is taxed.

Frequently asked questions
Is Reserve Forces training pay taxable?
Yes. Pay received for annual training commitments (typically around 27 days a year for most reservists, plus additional training days) is taxable income, assessed alongside any civilian employment income for the tax year, using the standard Personal Allowance and income tax bands.
How is pay taxed if I am mobilised for full-time service?
Mobilisation pay (received when a reservist is called up for full-time regular service, for example on an operational deployment) is also taxable, generally at rates aligned with the equivalent regular forces pay for the role and rank. It is taxed through the Ministry of Defence's own payroll system using the standard PAYE rules, in the same way as any other employment income.
Do reservists pay National Insurance on their reserve pay?
Yes, Class 1 National Insurance is generally due on reservist pay in the same way as on any other employment income, whether that is training pay or mobilisation pay, subject to the same £12,570 Primary Threshold and 8%/2% rate structure that applies to civilian employment.
What happens to my civilian salary and NI while I'm mobilised?
This depends entirely on your civilian employer's own policy — some employers continue to pay full or partial salary during mobilisation (sometimes topping up the difference between civilian and forces pay), while others do not pay salary at all during the period of mobilised service, in which case your income during that period is solely your forces pay, taxed separately through MOD payroll.
Can my civilian employer claim compensation for my absence during mobilisation?
Yes. Employers of mobilised reservists can claim compensation from the Ministry of Defence for certain costs associated with a reservist's absence, such as the cost of hiring and training a temporary replacement, intended to reduce the financial disincentive for employers to support staff who are also reservists. This compensation is separate from, and does not affect, the reservist's own personal tax position.
Does having two sources of pay in one tax year (civilian plus reservist) create tax complications?
It can, in the same way that any two-job PAYE situation can create tax code allocation issues (one employer/payer given your Personal Allowance, the other taxed at a flat rate). If your combined tax deducted across your civilian job and your MOD reservist pay does not match your true combined liability, this typically self-corrects via an end-of-year reconciliation, or can be proactively addressed by contacting HMRC about your tax code allocation across the two payers.
Is there a tax-free bounty or lump sum for reservists?
Some reserve forces schemes have historically included a tax-free annual bounty or similar payment for meeting minimum training and attendance commitments, though the exact structure, eligibility and tax treatment can change between reserve force schemes and years — check current Ministry of Defence and reserve forces guidance for the specific position applicable to your service and rank.
Does reservist pay affect student loan repayments?
Yes — reservist pay counts as income for student loan repayment purposes in the same way as any other employment income, so if your combined civilian and reservist income in a tax year exceeds your student loan repayment threshold, repayments are due on the excess, whether the income came from one source or was split across both.
Do reservists get any specific pension benefit for their service?
Many reserve forces have their own pension scheme (broadly parallel in principle to the regular forces pension scheme, though with rules reflecting reserve rather than full-time service patterns), separate from any civilian workplace pension a reservist may also be contributing to through their main employment.
